Objective : To assess intra- and interobserver reproducibility of Sanders Classification System of calcaneal fractures among experienced and less experienced observers. Methods : Forty-six CT scans of intra-articular calcaneal fractures were reviewed. Four observers, two with ten years of experience in foot and ankle surgery and two third-year residents in Orthopedics and Traumatology classified the fractures on two separate occasions three weeks apart from each other. The intra and inter-observer reliability was analyzed using the Kappa index. Results : There was good intraobserver reliability for the two experienced observers and one less experienced observer (Kappa values 0.640, 0.632 and 0.629, respectively). The interobserver reliability was fair between the experienced observers (Kappa = 0.289) and moderate among the less experienced observers (Kappa = 0.527). Conclusions : The Sanders Classification System showed good intraobserver reliability, but interobserver reproducibility below the ideal level, both among experienced and less experienced observers.

OBJETIVO: Análise retrospectiva da etiopatogenia, diagnóstico e opções de tratamento nos casos de tendinopatias do compartimento anterior do tornozelo (TCAT). MÉTODO: No período de setembro de 1998 a fevereiro de 2009, 13 pacientes foram operados por tendinopatia do compartimento anterior do tornozelo. A casuística constou de 10 pacientes do sexo masculino e três do feminino. O lado direito foi acometido em 12 pés e um do esquerdo. A média de idade foi de 35 anos (15-67). A etiologia foi traumática em oito pacientes e em cinco, degenerativa (atraumática). O tempo médio do diagnóstico ao tratamento foi de 19 meses (1-60) e o seguimento foi de 34 meses (4-127). O diagnóstico foi feito através da história e exame clínico. A ressonância magnética foi realizada em nove pacientes para estadiamento e planejamento. O tratamento cirúrgico foi personalizado para cada caso (sinovectomia, ressecção de ventre muscular, solidarização com o tendão adjacente e enxerto livre de tendão semitendíneo). Para a avaliação dos resultados foram utilizadas as escalas: 1) graduação subjetiva de satisfação, 2) AOFAS e 3) Maryland. RESULTADO: Em relação à escala de graduação subjetiva de satisfação, 12 pacientes satisfeitos e um paciente insatisfeito. A média da escala AOFAS foi de 80 pontos, a média da escala Maryland foi de 86 pontos. CONCLUSÃO: O tratamento cirúrgico é eficaz para recuperação funcional. As técnicas cirúrgicas devem ser personalizadas. A opção do enxerto livre de tendão semitendíneo é eficiente nas falhas maiores que cinco centímetros.

OBJECTIVE: To carry out a retrospective analysis of the etiopathogeny, diagnosis and therapeutic options in cases of tendinopathies of the anterior compartment of the ankle. METHOD: 13 patients underwent surgery between September 1998 and February 2009; ten men and three women. The right side was involved in twelve patients and the left in one. The averaging age was 35 years of age (15-67). The etiology was traumatic in eight patients and degenerative (non-traumatic) in five. The average time to diagnosis was 19 months (1 - 60) and the average follow-up time was 34 months (4 - 127). The diagnosis was made by anamnesis and clinical findings. Magnetic resonance imaging was performed in nine patients, for staging and planning. The surgical treatment was personalized in each case (debridement, resection of the muscle, grafting with the adjacent tendon, and free graft of the semitendinosus tendon). The following scales were used for the evaluation: 1) subjunctive satisfaction scale, 2) AOFAS and 3) Maryland. RESULTS: In relation to the subjective satisfaction scale, 12 patients were satisfied and one was dissatisfied. The average AOFAS scale was 80 points, and the average Maryland scale was 86 points. CONCLUSION: Surgical treatment is effective for restoring function. The surgical techniques must also be personalized. The free graft of the semitendinosus tendon option is effective for gaps larger than five centimeters.
