RESUMO Objetivo: Analisar os casos de epifisiólise do fêmur proximal operados pelo serviço de Ortopedia Pediátrica do Hospital Risoleta Tolentino Neves (HRTN), Belo Horizonte/MG, entre os anos de 2016 e 2019. Métodos: Foram analisados retrospectivamente os pacientes submetidos a tratamento cirúrgico de epifisiólise no Hospital Risoleta Tolentino Neves entre janeiro/2016 a janeiro/2019. Os dados coletados para análise foram: sexo, idade, lado acometido, cirurgia realizada, complicações pós-operatórias. Resultados: De janeiro de 2016 a janeiro de 2019, foram tratados 21 pacientes no HRTN. Houve predomínio do sexo feminino (57%), com média de idade de 12 anos. Cerca de 80% dos pacientes apresentaram quadro de epifisiólise crônica/ crônica-agudizada no primodiagnóstico. O lado esquerdo foi ligeiramente mais acometido em relação ao direito (6:5), com bilateralidade de 47%. A necrose avascular foi a complicação mais frequente, em 33% dos casos. Conclusão: Trata-se de quadro de alta morbidade associada, devendo haver um diagnóstico precoce, investigação de distúrbios endócrinos e tratamento cirúrgico adequado, visando uma melhora do prognóstico clínico e funcional do paciente. Nível de Evidência II, Estudo retrospectivo.

ABSTRACT Objective: To analyze the cases of slipped capital femoral epiphysis (SCFE) submitted to surgery at the Pediatric Orthopedics Surgery service of the Hospital Risoleta Tolentino Neves (HRTN), Belo Horizonte/MG, between 2016 and 2019. Methods: Patients treated for SCFE at the HRTN between January/2016 and January/2019 participated in this study. The following data were collected: gender, age, affected side, procedure performed, and postoperative complications. Results: Twenty-one patients were treated at HRTN during the specified period. Among these, most were female (57%) with mean age of 12 years. At the initial diagnosis, about 80% of the patients presented with chronic/acute-on-chronic epiphysis. The left hip was slightly more affected than the right (6:5), with a bilateral rate of 47%, and avascular necrosis was the most frequent complication, occurring in 33% of cases. Conclusion: Slipped femoral capital epiphysis is associated with high morbidity; thus, early diagnosis, endocrine disorder investigation, and appropriate surgical treatment are key for improving these patients’ clinical and functional outcome. Level of Evidence II, Retrospective study.

OBJECTIVES: This study aimed to correlate a higher Pelvic-Trochanteric Index (PTI) with an increased varus of the femoral neck with greater trochanteric pain syndrome (GTPS). The secondary objective was to check whether the pelvic width changes with age. METHODS: A prospective study was conducted to compare female patients diagnosed with GTPS (case group) with asymptomatic female participants (control group) from March 2011 to June 2017. On an anteroposterior pelvic radiograph, lines were drawn by two radiologists, and the PTI (ratio of the distance between the greater trochanters and distance between the iliac crests) was defined and the femoral neck-shaft angle was measured. RESULTS: Data collected based on radiographs of 182 female patients (cases) and 150 female participants (controls) showed that the mean PTI was 1.09 (SD=0.01) in the case group and 1.07 (SD=0.01) in the control group (p<0.05), regardless of age. The distance between iliac crests increased with age (p<0.05) in symptomatic and asymptomatic individuals. It was also found that the mean femoral neck-shaft angle was 130.6° (SD=0.59) and progression of the varus angulation occurred with age in both groups, with a significance level of 5%. CONCLUSIONS: The PTI was higher in patients with GTPS. The femoral neck-shaft angle does not differ between individuals with and without GTPS; however, it does decrease with age. The pelvic width tends to increase with aging in symptomatic or asymptomatic individuals; therefore, the increase in the pelvic width and decrease in the femoral neck-shaft angle can be interpreted as normal in aging women, which could alter the biomechanics of the hips and pelvis.

Resumo Objetivo Investigar a incidência de infecção em pacientes com fraturas por arma de fogo, e correlacionar esse achado com a ocorrência de desbridamento cirúrgico na sala de emergência. Métodos Estudo retrospectivo, observacional e descritivo, que incluiu todos os casos de fraturas causadas por armas de fogo entre janeiro de 2010 e dezembro de 2014; foram incluídas 245 fraturas em 223 pacientes. Resultados Houve infecção do local cirúrgico em 8,5% das fraturas, e a média de desbridamentos necessários para controlar o processo infeccioso foi de 1,273 ± 0,608. Foi identificada correlação entre o tratamento cirúrgico escolhido e o segmento corporal afetado (p< 0,001). O tratamento cirúrgico na sala de emergência teve correlação com a ocorrência de infecção (p< 0,001; teste do qui-quadrado). Conclusão Pacientes com ferimentos à bala tratados de forma não operatória apresentaram lesões menos graves e estáveis; portanto, a incidência de complicações nesse grupo foi menor. Por outro lado, os pacientes com lesões complexas foram aqueles submetidos a desbridamento e fixação externa. Portanto, como esperado, foi encontrado um maior número de complicações infecciosas em pacientes submetidos à fixação externa.

Abstract Objective To investigate the incidence of infection in patients with gunshot-related fractures, and to correlate this finding with the occurrence of surgical debridement in the emergency room. Methods A retrospective, observational, descriptive study that included all cases of fractures caused by firearms between January 2010 and December 2014; 245 fractures in 223 patients were included. Results There was surgical-site infection in 8.5% of the fractures, and the mean number of debridements required to control the infectious process was of 1.273 ± 0.608. A correlation was identified between the surgical treatment chosen and the affected body segment (p< 0.001). The surgical treatment in the emergency room had a correlation with the occurrence of infection (p< 0.001; Chi-squared test). Conclusion Patients with gunshot injuries treated non-operatively presented less severe and stable lesions; thus, the incidence of complications in this group was found to be lower. On the other hand, those patients with complex lesions underwent debridement and external fixation. Therefore, a greater number of infectious complications in patients submitted to external fixation was found, as expected.

Abstract Objective To evaluate the inter- and intraobserver reliability of the Outerbridge, Beck, and Haddad classifications for acetabular joint cartilage lesions through the arthroscopic procedure. Methods A total of 60 hip arthroscopy videos were evaluated twice by 4 surgeons at 2 different times to assess the inter- and intraobserver reproducibility of the classifications, and the data was analyzed by means of the weighted Cohen Kappa index. Results The mean weighted Kappa values in the interobserver assessment of the Outerbridge, Beck, and Haddad classifications were, respectively, 0.72, 0.78, and 0.68. The three classifications were considered as presenting good interobserver agreement. Regarding the intraobserver assessment of the Outerbridge, Beck, and Haddad classifications, the weighted Kappa values were, respectively, 0.9, 0.9, and 0.93. The three classifications were considered as presenting excellent intraobserver agreement. Conclusion In the present series, the Outerbridge, Beck, and Haddad classifications presented good interobserver reproducibility and excellent intraobserver reproducibility when evaluating acetabular chondral lesions by the arthroscopic approach.

RESUMO A fratura-avulsão da tuberosidade anterior da tíbia é uma lesão incomum que ocorre no jovem atleta, resultado de uma contração excêntrica do mecanismo extensor do joelho com o membro inferior fixo ao solo. Lesões concomitantes ao tendão patelar são muito raras, com poucos casos relatados na literatura. Os autores apresentam o caso de um atleta de basquete de 15 anos que sofreu uma fratura-avulsão da tuberosidade anterior da tíbia associada à ruptura completa distal do tendão patelar durante movimento de arremesso no treino esportivo. O paciente foi tratado com redução aberta da fratura e reparo do tendão patelar com miniâncoras e parafuso poste com reforço tendinoso com enxerto autólogo de semitendíneo. O paciente apresentou ótimos resultados e retornou ao esporte após 12 meses de acompanhamento.

ABSTRACT Avulsion of the tibial tubercle is an uncommon injury that occurs in the young athlete, resulting from an eccentric contraction of the extensor mechanism with the leg fixed to the ground. Concomitant injuries to the patellar tendon are very rare, with few cases reported in the literature. The authors present a case of a 15-year-old basketball player who suffered an avulsion of the tibial tubercle associated with complete distal rupture of the patellar tendon while training. It was treated with open reduction of the tibial fragment and reconstruction of the patellar tendon with mini-anchors and cannulated screws, as well as hamstring autograft tendon reinforcement. The patient showed excellent results and returned to sports after 12 months of follow-up.

Abstract Purpose: To compare the influence of two metallic implants in the diagnosis of periprosthetic infection using 99m technetium-labeled ceftizoxime. Methods: Twenty rats were randomly divided into four groups, which received sterile and contaminated titanium and stainless steel implants. After 3 weeks, scintilographic images were obtained using a gamma chamber. Radioactivity counts were obtained for the region of interest (ROI) on the operated and non-operated paws. Results: Groups A, B, and C showed homogenous distribution of the radiopharmaceutical. Hyper uptake was observed in the operated paw from group D. The ROI target count was higher in the two groups with stainless steel implants. Among the control groups, the count was higher in the stainless steel group. Furthermore, among the contaminated groups, the uptake was higher in the stainless steel group, with a significant difference. The target: non-target ratio was significantly lower in the control and contaminated groups with both titanium and stainless steel, but the comparison between control groups and contaminated groups was only significant in the former. The cpm/g observed after a decay of 48h showed statistically significant differences between groups. Conclusion: Different biomaterials used in implants have an influence on the results of scintigraphy with 99mTc-CFT.

ABSTRACT Objective: To evaluate the rate of local recurrence of extra-abdominal desmoid tumor and compare the outcomes of surgical treatment and conservative treatment. Methods: Twenty one patients (14 women and seven men), mean age 33.0±8.7 years old, with a diagnosis of desmoid tumor were evaluated. The mean follow-up period was 58.5±29.0 months. Fourteen cases involved the lower limbs, four cases involved the upper limbs, and three cases involved the trunk. The average tumor size was 12.7±7.5 cm. Of the 21 patients, 14 did not undergo previous treatment and seven patients relapsed before the initial evaluation. Surgical treatment was performed in 16 patients and conservative treatment was performed in five patients. Results: Recurrence occurred in seven patients (33%) and six of them relapsed within the first 18 months. No significant difference was observed between conservative and surgical treatment. However, a significant difference was observed among patients undergoing wide resection and who experienced improved local control. Conclusion: The recurrence rate of desmoid tumor was 33.3%. There was no difference in recurrence between conservative and surgical treatment. In surgical treatment, wide margins showed better results for recurrence control. Level of Evidence III. Retrospective Observational Study.

ABSTRACTOBJECTIVE: To investigate the influence of patients' age on the delay between diagnosis and surgical treatment of proximal femoral fracturesMETHODS: This is a retrospective study, con-ducted at a tertiary university hospital, including all patients admitted with proximal femoral fractures between March 2013 and March 2014. The participants were categorized into four groups according to age levels. The groups were compared according to demographics, comorbidities, fracture type, trau-ma circumstances, and time between diagnosis and surgical procedureRESULTS: One hundred and sixty one patients were included, 37 adults and 124 elderly. Among adults, the mean delay between diagnosis and surgical procedure was 6.4±5.3 days; among elderly the delay was 9.5±7.6 days. There was a progressive increase in the delay from the young-adults group through the elderly individuals (Kruskal-Wallis: 13.7; p=0.003)CONCLUSION: In spite of being the patients most susceptible to complications due to surgical delay, the elderly individuals pre-sented the longest delays from admission to surgical treatment. Level of Evidence III, Retrospective Study.

Objetivo:Avaliar o impacto de um ambulatório de pé diabético na redução da morbidade da doença, com ênfase nas lesões dos membros inferiores.Métodos:Estudo prospectivo, observacional, com população alvo de 30 casos do total de 77 pacientes do ambulatório de pé diabético. O critério de inclusão foi que todos os pacientes tivessem exames laboratoriais, exame clínico, testes neuropático e vascular e índice tornozelo-braço repetidos após 18 meses de acompanhamento, o que permitiu analisar sua evolução. A análise estatística foi feita com o teste qui-quadrado de MacNemar para amostras dependentes.Resultados:A média de idade dos pacientes foi de 61 anos, todos portadores de diabetes mellitus (DM) tipo 2, iniciada em média havia 14,5 anos, e 20% eram neuropatas. Após 18 meses, não houve mudança na frequência de lesão em órgão alvo da diabetes (p = 1,000) e no índice de neuropatía (p = 1,000). Obteve-se, no entanto, melhoria significativa dos sintomas neuro-páticos de 70% para 36,7% (p = 0,035), bem como da doenca arterial periférica de 73,3% para 46,7% (p = 0,021). Foi observada ainda diminuição de 13,3% para 10% das úlceras (p = 1,000).Conclusões:A criação de ambulatórios especializados em prevenção do pé diabético é investimento viável, de baixo custo quando comparado aos altos custos gerados pelas complicates dessa doenca. Essa abordagem melhora sensivelmente a qualidade de vida do paciente, com a redução da morbidade.

Objective:To assess the impact of a diabetic foot outpatient clinic on reducing the morbidity of this disease, with emphasis on lower-limb lesions.Methods:This was a prospective observational study with a target population of 30 cases out of a total of 77 patients in the diabetic foot outpatient clinic. The inclusion criterion was that data relating to laboratory tests, clinical examinations, neuropathic and vascular tests and the elbow-arm index needed to be available from all the patients, with repetition after 18 months of follow-up, so as to analyze their evolution. The statistical analysis was done using the McNemar chi-square test for dependent samples.Results:The patients' mean age was 61 years. All of them had type 2 diabetes mellitus (DM), which had started 14.5 years previously, on average, and 20% had neuropathies. After 18 months, there was no change in the frequency of lesions in diabetes target organs (p = 1.000) or in the neuropathy rate (p = 1.000). However, there were significant improvements in neuropathic symptoms, from 70% to 36.7% (p = 0.035), and in peripheral arterial disease, from 73.3% to 46.7% (p = 0.021). There was also a decrease in ulcers from 13.3% to 10% (p = 1.000).Conclusions:Creation of specialized outpatient clinics for prevention of diabetic foot is a viable investment, which has low cost compared with the high costs generated through the complications from this disease. This approach noticeably improves the patients' quality of life, with reduction of morbidity.

Objetivo:Testar a hipótese nula de que os pacientes com a tríade terrível do cotovelo (luxação associada a fraturas da cabeça do rádio e do processo coronoide) tratados com redução aberta e fixação interna da cabeça do rádio têm resultado final comparável aos pacientes tratados com artroplastia ou ressecção parcial da cabeça do rádio.Métodos:Foram avaliados, em média aos 23 meses (16 a 36) após a cirurgia, 26 pacientes com a tríade terrível do cotovelo operados por um único cirurgião. Eram 17 homens e nove mulheres, com média de idade de 41 anos (± 13,4). As fraturas da cabeça do rádio foram tratadas com osteossíntese (12 pacientes), ou artroplastia (nove), ou ressecção de um fragmento pequeno ou nenhum tratamento (cinco). Fixação do processo coronoide/cápsula anterior foi feita em 21 pacientes. O complexo ligamentar lateral (LCL) foi reparado em todos os pacientes, enquanto que o complexo ligamentar medial (LCM) foi reparado em três pacientes cujos cotovelos persistiam instáveis após o tratamento da cabeça do rádio e do LCL, mas sem fixação do processo coronoide.Resultados:O arco final médio de flexão e extensão foi de 112°. A pronação média foi de 70° e a supinação, de 6°. O escore Dash (Disabilities of Arm, Shoulder & Hand) médio foi de 12 e o Mepi (Mayo Elbow Performance Index) médio foi de 87. De acordo com o Mepi, 21 pacientes (80%) tiveram bons e excelentes resultados. Não houve diferença estatisticamente significativa entre os resultados dos pacientes submetidos a fixação da cabeça do rádio e aqueles submetidos a artroplastia ou ressecção de um fragmento pequeno.Conclusão:Não há diferença entre os pacientes tratados com a artroplastia da cabeça do rádio daqueles tratados com outras técnicas.

Objective:To test the null hypothesis that patients with the terrible triad of the elbow (dislocation together with fractures of the radial head and coronoid process) who are treated with open reduction and internal fixation of the radial head have final results that are comparable with those of patients treated with arthroplasty or partial resection of the radial head.Methods:Twenty-six patients with the terrible triad of the elbow who were operated by a single surgeon were evaluated on average 23 months after the surgery (range: 16–36 months). There were 17 men and nine women of mean age 41 ± 13.4 years. The fractures of the radial head were treated by means of osteosynthesis (12 patients), arthroplasty (nine) or resection of a small fragment or no treatment (five). Fixation of the coronoid process/anterior capsule was performed in 21 patients. The lateral ligament complex (LLC) was repaired in all the patients, while the medial ligament complex (MLC) was repaired in three patients whose elbows remained unstable after treatment for the radial head and LLC, but without fixation of the coronoid process.Results:The mean final range of flexion and extension was 112°. The mean pronation was 70° and supination, 6°. The mean DASH score (Disabilities of the Arm, Shoulder & Hand) was 12 and mean MEPI (Mayo Elbow Performance Index) was 87. According to the MEPI scores, 21 patients (80%) had good and excellent results. There was no statistically significant difference in the results between the patients who underwent fixation of the radial head and those who underwent arthroplasty or resection of a small fragment.Conclusion:There was no difference between the patients treated with arthroplasty of the radial head and those treated with other techniques.

OBJETIVO: Avaliar os resultados do tratamento da lombalgia crônica discogênica com a técnica IDET (Intradiscal Electrothermal Therapy) em um acompanhamento maior que dois anos de pós-operatório (PO). MÉTODOS: Estudo prospectivo, avaliando 23 pacientes consecutivos com diagnóstico de lombalgia crônica discogênica tratados com IDET entre fevereiro de 2003 e fevereiro de 2006. A dor foi considerada discogênica em caso de discografia positiva ou imagem compatível com a ressonância magnética, segundo os critérios de Horton e Daftari. Os parâmetros clínicos (EVA e Oswestry) foram avaliados no pré-operatório, no retorno com 6, 12, 18, 24 e mais de 48 meses de pós-operatório. RESULTADOS: A média de idade dos pacientes foi de 42,09 (variação de 26 a 51 anos). A média do período do acompanhamento foi de 32,55 meses (variação de 6 a 68 meses). A média do índice de dor (EVA) foi de 7,07 ± 1,90, reduzindo-se para 2,47 ±1,876 em 6 meses, 2,69 ±1,82 em 12 meses, 3,63 ±1,75 em 18 meses e 5,73 ±2,12 em 24 meses. A média do índice Oswestry foi de 39,26 ± 11,96 no pré-operatório, reduzindo-se para 19,44±15,72 em 6 meses, 19,8 8 ±15,45 em 12 meses, 26,62 ±13,84 em 18 meses e 31,87 ±14,94 em 24 meses. Os resultados não se mantiveram no acompanhamento de 48 meses. CONCLUSÃO: O IDET mostrou resultados satisfatórios como alternativa paliativa no controle da dor e da incapacidade funcional num período de 24 meses. Os bons resultados deterioraram-se com 48 meses e houve uma tendência de retorno à sintomatologia inicial.

OBJECTIVES: Evaluate the results of treatment of patients with chronic discogenic low back pain who have been submitted to IDET (Intradiscal Electrothermal Therapy). Minimum post operatory follow up was two years. METHODS: Prospective study of 23 patients diagnosed with chronic discogenic low back pain who received treatment between February 2003 and February 2006. The disk was considered the source of the pain in case of a positive discography or a nuclear magnetic resonance image compatible with Horton and Daftari criteria. Clinical parameters (VAS and Oswestry) were evaluated during pre-operatory and at 6, 12, 18, 24 and 48 months after surgery. RESULTS: The average age of patients was 42,09 years (26 to 51 years). The mean follow up time was 32,55 months (6 to 68 months). The mean visual analog scale (VAS) was 7,07 ± 1,90, and was reduced to 2,47 ±1,876 at 6 months, 2,69 ±1,82 at 12 months, 3,63 ±1,75 at 18 months and 5,73 ± 2,12 at 24 months. Oswestry index average was 39,26 ± 11,96 before surgery. It was reduced to 19,44±15,72 6 months after surgery, 19,8 8 ±15,45 12 months, 26,62 ±13,84 18 months and 31,87 ±14,94 24 months after the procedure. Favorable results were not seen after a 48-month follow up. CONCLUSION: IDET technique has proved to be a good alternative in the palliative control of pain and functional incapacity during a 24-month period. Good results have deteriorated after 48 months, with a tendency to return of symptoms as they were prior to treatment.

OBJETIVO: Descrever e comparar clínica e radiograficamente pacientes submetidos a artroplastia total do joelho (ATJ) com implantes tibiais tipo all-polyethylene (ALP) e metal-backed (MTB). MÉTODOS: Pacientes submetidos a ATJ realizadas entre janeiro de 1998 e dezembro de 2004 foram agrupados de acordo com o tipo de implante recebido: all-polyethylene ou metal-backed. Sessenta pacientes compareceram para a avaliação, totalizando 82 joelhos operados. Destes, 22 pacientes haviam sido submetidos a ATJ apenas com ALP (12 unilaterais e 10 bilaterais), 33 pacientes apenas com MTB (26 unilaterais e sete bilaterais) e cinco pacientes foram submetidos a ATJ com ALP em um joelho e MTB em outro joelho, assim divididos: Grupo 1-37 joelhos com ALP e Grupo 2 - 45 joelhos com MTB. RESULTADOS: Não houve diferença na avaliação clínica e funcional entre os grupos. A média de radioluscência no fêmur foi de 0,838mm para os pacientes do grupo 1 e 0,356mm para os pacientes do grupo 2 (p = 0,049). Para a tíbia, na incidência AP, houve um valor médio de 2,703mm para o grupo 1 e de 0,733mm para o grupo 2 (p = 0,000). Na incidência em perfil, o valor médio de osteólise foi de 0,405mm para o grupo 1 e de 0,200mm para o grupo 2 (p = 0,074). CONCLUSÕES: Não houve diferença entre os grupos na avaliação clínica e funcional. Houve aumento da radioluscência nas artroplastias com ALP, tanto no fêmur na incidência em perfil quanto na tíbia na incidência em AP. Nível de evidência IV - Estudo tipo série de caso.

OBJECTIVE: To evaluate and clinically and roentgenographically compare two populations who had undergone total knee arthroplasty (TKA) with all-polyethylene (ALP) and metal-backed (MTB) tibial components. METHODS: Two groups of 40 patients underwent TKA between January 1988 and December 2004. Sixty patients showed up for evaluation, totaling 82 operated knees. From these, 22 patients had undergone TKA with only ALP (12 unilateral and 10 bilateral), 33 patients with only MTB (26 unilateral and 7 bilateral) and 5 patients had undergone both implants. The 82 operated knees were divided into two groups according to the type of tibial implant: Group 1 - 37 knees with ALP and Group 2 - 45 knees with MTB. RESULTS: There was no clinical or functional difference in outcome between the studied groups. The measurement of radioluscent line in the femoral component averaged 0.838 mm in Group 1 and 0.356 mm in Group 2 (p=0.049). For the tibial component, in the AP view radioluscent line measurement averaged 2.703 mm in Group 1 and 0.733 mm in Group 2 (p=0.000); and in the lateral view, the average values were 0.405 mm in Group 1 and 0.200 mm in Group 2 (p=0.074). CONCLUSIONS: There was no difference in the functional or clinical outcomes between the groups. However, radioluscent line was observed more frequently in the ALP arthroplasty group, in the lateral view in the femoral component as well as the AP view of the tibial component. Level of evidence IV - case series study.

OBJETIVO: O objetivo deste trabalho é avaliar prospectivamente o padrão de evolução e complicações pós-operatórias relacionadas ao uso de drenos de sucção quando comparado à não utilização destes dispositivos na ATJ. MÉTODOS: Foram incluídos 42 pacientes de um serviço de referência em cirurgia do joelho. Quinze pacientes não receberam e 27 receberam dreno de sucção no pós-operatório. Os parâmetros avaliados foram: amplitude de movimento (ADM), índices hematimétricos, circunferência do joelho e taxa de complicações. O período de observação estendeu-se até o sexto mês de pós-operatório. RESULTADOS: Não foi observada diferença estatisticamente significativa entre os grupos quanto à circunferência do joelho, hemoglobina, hematócrito, taxa de transfusão e índice de infecção. Com relação à amplitude de movimentos, não houve diferença estatística entre os grupos com e sem dreno no pré-operatório (p = 0,126), primeiro DPO (p = 0,583), quinto ao sétimo DPO (p = 0,076) e seis meses de pós-operatório (p = 0,848). Foi identificada diferença estatisticamente significante entre os grupos na avaliação entre o 14º e 28º DPO (p = 0,025). CONCLUSÃO: Este estudo conclui que não existe benefício no uso de dreno de sucção fechado na ATJ além de seis meses de pós-operatório. No entanto, a ADM ao final do primeiro mês é melhor no grupo que utilizou o dreno de sucção.

OBJECTIVE: Our aim is to prospectively evaluate the standard evolution and post-operative complications related to the use of suction drainage devices when compared to not using these devices in TKA. METHODS: Forty-two patients from a clinic referred to knee surgery were included. Fifteen patients did not receive suction drainage postoperatively and 27 received suction drainage. The parameters evaluated were the range of movement, hematometric indices, knee circumference, and complications for each group. Patients were observed for six months after the surgical procedure. RESULTS: There were no statistically significant differences in knee circumference, hemoglobin, hematocrit, transfusion rate, and infection index. The analysis of the range of movement did not reveal statistically significant differences between the groups preoperatively (p=0.126), during the first postoperative day (p=0.583), fifth to seventh postoperative day (p=0.076) and at six months follow-up (p=0.848). There was a statistically significant difference between groups in the comparison during the 14th and 28th postoperative days (p=0.025). CONCLUSION: In conclusion, there is no benefit to using closed suction drains beyond six months after TKA. However, the range of movement at the end of the first month is superior in patients that received suction drainage.

OBJETIVO: Demonstrar por meio de ensaios biomecânicos comparativos entre a placa-lâmina de 95º e o parafuso condilar dinâmico (Dynamic Condylar Screw - DCS), qual apresenta maior resistência às cargas compressivas e de flexão, bem como tentar correlacionar o tipo de falha apresentada durante os testes com cada um dos tipos de placa. MÉTODOS: Sessenta e cinco fêmures suínos foram submetidos a osteotomia em cunha de subtração medial de um centímetro (cm), na região metafisária distal do fêmur, com o objetivo de simular fratura supracondiliana instável. Foi realizada osteossíntese dessas peças, sendo 35 fixadas com placa-lâmina 95º e 30 com placas com DCS, submetendo-as a cargas em compressão axial e flexão. Outra variável estudada foi o tipo de falha apresentada em cada grupo com a tentativa de correlacioná-la com o tipo de placa. RESULTADOS: Os resultados não mostraram diferença estatisticamente significante na resistência biomecânica entre os dois tipos de placas ou entre o tipo de falha e a placa utilizada na osteossíntese. CONCLUSÃO: Os dois tipos de placas se comportam de maneira semelhante, embora haja um indicativo de que a placa-lâmina seja, no ensaio de flexão, superior à placa DCS. Não foi observada diferença entre o tipo de falha e o tipo de placa utilizada.

OBJECTIVE: to determine, by means of comparative biomechanical tests between the 95o angled blade plate and the dynamic condylar screw (DCS), the one that presents greater compressive load resistance and flexion, and to correlate the failure type presented during the tests with each type of plate. METHODS: Sixty-five porcine femurs were submitted to a 1 cm medial wedge osteotomy, in the metaphysic, to simulate an unstable supracondylar femoral fracture. Osteosynthesis of these pieces was performed: 35 were fixated with a 90o lateral blade plate, and 30 with DCS plates. Another variable studied was the failure type presented in each group, attempting to correlate this with the type of plate. RESULTS: The results showed no statistically significant differences in biomechanical resistance between the two types of plates, or between the failure type and the plate type used in the osteosynthesis. CONCLUSION: THE TWO TYpes of plate behaved in a similar fashion. However, the angled blade plate proved to be superior to the DCS in the flexion test. No statistical difference was observed in failure type or type of plate used.
