METHODS: The sample consisted of 52 individuals with ages ranging from 18 to 28 years old. The procedures related to radiographic image collection were carried out in collaboration with a diagnostic imaging center of a hospital in Curitiba, PR, Brazil. The angles of the lumbosacral concavity were evaluated by the following methods: Centroid, Cobb1L1-S1, Cobb2L1-L5, Cobb3L2-S1 Cobb4T12-S1, Posterior Tangent and Trall. RESULTS: High correlation coefficients (r ranging from 0.77 to 0.89) were found among variations of the Cobb method. Additionally, we propose a categorical classification of angle values obtained by each method. We also analyzed the influence of the level of the inflection point between the lumbar lordosis and thoracic kyphosis in determining the evaluation method to be used. The inflection point had a higher incidence in the region between the twelfth thoracic vertebra and the first lumbar vertebra (63.5%). CONCLUSION: The correlation and agreement between methods vary considerably. Moreover, the thoracolumbar inflection point should be considered when choosing the method of assessing patients.

An anatomical study]]> http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1413-78522015000200072&lng=es&nrm=iso&tlng=es OBJECTIVE: The relationship of Gantzer muscle to the median and anterior interosseous nerve is debated. METHODS: Ìn an anatomical study with 80 limbs from 40 cadavers the incidence, origin, insertion, nerve supply and relations of Gantzer muscle have been documented. RESULTS: The muscle was found in 54 forearms (68% of limbs) and was supplied by the anterior interosseous nerve. It arose from the deep surface of the flexor digitorum superficialis muscle, (42 limbs), coronoid process (eight limbs) and medial epicondyle (seven limbs). Its insertion was to the ulnar part of flexor pollicis longus muscle. The Gantzer muscle always lay posterior to both the median and anterior interosseous nerve. CONCLUSION: The Gantzer muscle may contribute to the median nerve and anterior interosseous nerve compression. The muscle was found in 68% of limbs and should be considered a normal anatomical pattern rather than an anatomical variation.

METHODS: Between February 2011 and June 2013, 100 wrists of 88 patients were included in the study. All patients were subjected to corticoid injections in the carpal tunnel and evaluated before and after infiltration and surgery. The following parameters were evaluated: visual analog scale (VAS) for pain, Boston questionnaire, sensitivity and strength. RESULTS: Only 28 out of 100 wrists subjected to injection were symptom-free after six months follow up. Sixty out of the 72 patients who did not present relief or relapse symptoms were treated surgically. Surgical results were better regarding VAS, Boston questionnaire and sensitivity in a specific group of patients, which had a longer relief of symptoms after the corticoid injection, with statistical significance. CONCLUSION: Longer relief of symptoms after corticoid injection correlated with better results of surgical treatment.

METHODS: Two instruments (WHOQOL-BREF and DASH) were applied to evaluate the quality of life and functional capacity of patients with adhesive capsulitis. Inclusion criteria were age between 35 and 75 years old and achievement of shoulder imaging. Each domain of the WHOQOL-BREF was correlated with DASH. Pearson's correlation coefficient was used for parametric variables and Spearman's correlation coefficient was used when at least one variable had a non-normal distribution. The level of significance was p &lt;0.05. RESULTS: Forty three patients with mean age of 54.7 years old were evaluated. The mean values found in the physical, psychological, social and environmental domains of the WHOQOL-BREF and DASH were 45.3, 63.9, 68.2, 60.2 and 61.6, respectively. A moderate negative correlation was found between DASH and the physical domain of WHOQOL-BREF (r= - 0.583, p&lt;0.001). CONCLUSION: The only domain where WHOQOL-BREF correlates with DASH is the physical domain, suggesting that measures to promote the improvement of functional capacity may lead to better quality of life of patients with adhesive capsulitis.

METHODS: From August 2002 to December 2004, ten patients underwent arthroscopic capsular release for adhesive capsulitis refractory to conservative treatment. An interscalene catheter was used for postoperative analgesia, before the procedure. All were in stage II, with a minimum follow up of six years. The mean age was of 52.9 years old (range, 39 to 66), with female predominance (90%) and six left shoulders. The time between the onset of symptoms and surgery varied from six to 20 months. There were four patients in the primary form (40%) and six in the secondary (60%). RESULTS: In the preoperative evaluation, the mean active anterior elevation was 92°, 10.5° of external rotation, and internal rotation level L5. Postoperatively, the mean active elevation was 149°, 40° of external rotation and internal level T12, respectively. Thus, the average gains were 57° in forward active elevation, 29.5° in external rotation and six spinous processes, these values being statistically significant (p &lt;0.001). According to the Constant functional score (arc of movements), the value increased from 13.8 (preoperative mean) to 32 points (postoperative mean). CONCLUSION: Arthroscopic treatment of adhesive capsulitis of the shoulder refractory to conservative treatment allows effective gain of range of motion of this joint.

METHODS: Forty knees from adult rabbits were impacted thrice with a 1 kg block released through a 1 meter tall cylinder (29.4 Joules). Subsequently, 2 mL of HA was injected in one knee and 2 mL saline in the contra-lateral knee. Medication were administered twice a week for 30 days, when animals were sacrificed. Specimens were prepared for optical microscopy exam and terminal deoxynucleotidyl transferase end labeling assay (TUNEL). RESULTS: The apoptosis rate in the contusion model was 68.01% (± 19.73%), a higher rate than previously described. HA significantly reduced the rate of apoptosis to 53.52% (± 18.09) (p &lt;0.001). CONCLUSION: Intra-articular HA administration started immediately after trauma reduces impact-induced chondrocyte apoptosis rates in rabbits.

METHODS: Prospective study with 169 participants, divided into two groups. Group A: 99 patients who were born and raised at altitude and group B: 70 patients who were born and raised at low altitude. All patients underwent panoramic radiographs of the pelvis, where we marked three measure and checked the thickness of the cortical and the lateral and medial cortical, as well as the thickness of the femoral canal. RESULTS: We noticed that the first measure showed no significant difference in both groups, but the second measure, the lateral cortex, is thicker in group A, and the femoral canal is smaller in comparison to group B. CONCLUSION: We concluded that patients who were born and raised at altitude have a smaller femoral canal. This may help in proper planning of future surgical procedures, especially in total hip arthroplasty cases.

METHODS: We analyzed the trabecular part of the femur of 13 female patients, aged over 60 years old, by the bone histomorphometry method. Seven of these patients had femoral neck fracture. All of them were subjected to hip arthroplasty. RESULTS: Bone densitometry showed no significant difference. There was no significant difference on the average thickness of the trabecular bone (124.38µm versus 147.09µm). The number of bone trabeculae was lower (1.52, versus 1.88) and the separation between them was larger (541,19µm versus 391,14µm) in the fracture group. CONCLUSION: A difference in histomorphometric parameters of cancellous bone of the femur neck was observed among patients who had fractures as compared to patients who had not.

METHODS: Biopsy of the iliac crest was made in seventeen patients between 55 and 90 years old who were admitted to the emergency room with fractures of the proximal end of the femur. After a small fragment was removed, we made a histomorphometric analysis of it. RESULTS: There was no significant difference between patients with femoral neck fracture and trochanteric fracture in structural parameters, formation and resorption. Comparing age groups we also did not find any significant change between the groups in the parameters volume and trabecular separation. CONCLUSION: There are no difference in the morphometric parameters analyzed between the different types of fracture and age is not a significant factor in the alteration of these parameters.

METHODS: This was a descriptive, exploratory and cross-sectional study with quantitative approach. Twenty seven patients were interviewed. The instruments have rated the sociodemographic, clinical and economic profile (semistructured interview) and the Quality of Life (generic Quality of Life questionnaire SF-12) and emotional factors (HAD scale) of the interviewed patients. RESULTS: It was identified that the most frequent amputations occur in males aged 18-38 years and are related to occupational accidents. The Quality of Life was compromised in both components of physical and mental health. Furthermore, anxiety levels were more prevalent in the range from aged 18 to 38 years old, while the levels of depression were most prevalent among the elderly (60 to 80 years old). CONCLUSION: The impairment of Quality of Life and change in the perception of body image has a major impact on adherence to the rehabilitation program and the functional prognosis. Therapeutic orientation is, therefore, critical after this type of surgery. Level of Evidence II, Descriptive and Exploratory Study.
