Objective: To analyze morphological abnormalities of the talus in patients with clubfoot after surgical treatment using the McKay technique. Method: Lateral standing-position radiographs of the feet of 14 patients with unilateral clubfoot who underwent treatment by means of the doubleincision McKay technique were retrospectively analyzed. All the patients were operated by the same surgeon, with an average of 6.53 years between surgery and the radiograph. We compared the radiographic characteristics of the talus between the operated and the contralateral foot. We assessed the presence of deformity of the talar dome and head (sphericity evaluation); the talar length and height; the percentage and degree of navicular subluxation; abnormalities of the Gissane angle; and the trabecular bone pattern. Results: Abnormalities of the talar head occurred in 92.8% of the patients; of the talar dome in 92.8%; and of the trabecular pattern in 100%. The talar length ratio between the operated and the contralateral foot ranged from 0.61 to 0.88 (mean 0.79; SD = 0.09), while the height ratio ranged from 0.57 to 0.98 (mean 0.82; SD = 0.12). The Gissane angle was greater in all of the operated feet, and all of them also showed navicular subluxation, at a rate ranging from 6.43 to 59.75% (mean 26.34%; SD = 16.66%). Conclusion: Talar abnormalities occurred in 100% of the feet treated using the McKay technique. It was shown that establishing radiographic parameters to describe and quantify these deformities was feasible, through simple and easy-to-perform techniques.

The authors report four unrelated girls presenting mild mental deficiency and a distinct malformation syndrome, mainly consisting of short stature, macrocranium, peculiar facies with prominent forehead, hypertelorism and exophthalmos, cardiac anomalies and cutis laxa with characteristic wrinkled palms and soles, typical ribs, small vertebral bodies and slender long bones. All were sporadic cases of non‐consanguineous parents of advanced age at their births, suggesting a de novo autosomal dominant mutation.

Objective: The aim of this study was to evaluate the approaches and procedures used by Brazilian orthopedic surgeons for treating osteoarthrosis by means of unicompartmental knee arthroplasty and high tibial osteotomy of the knee. Methods: A questionnaire with 14 closed questions was developed and applied to Brazilian knee surgeons during the three days of the 43rd Brazilian Congress of Orthopedics and Traumatology. Results: A total of 113 surgeons filled out the questionnaire completely and became part of the sample analyzed. In this study, the majority of the surgeons performed fewer than five unicompartmental knee arthroplasty procedures/year (61.1%) and between 5 and 15 high tibial osteotomy procedures/year (37.2%). Use of computerized navigation systems during surgery remains uncommon in our environment, since only 0.9% of the specialists were using it. 65.5% of the surgeons reported that they had chosen to use total knee arthroplasty rather than partial arthroplasty due to lack of familiarity with the surgical technique. When asked about the possibility that the number of unicompartmental prostheses used in Brazil would grow as surgeons in this country become increasingly familiar with the technique, 80.5% of the respondents believed in this hypothesis. In this sample, we found that the greater the surgeon's experience was, the greater the numbers of unicompartmental prostheses and tibial osteotomies performed annually were (r = 0.550 and r = 0.465, respectively; p < 0.05). Conclusions: There is a clear evolutional trend towards treatment of unicompartmental osteoarthritis using partial knee arthroplasty in Brazil. However, further prospective controlled studies are needed in order to evaluate the clinical and scientific benefits of these trends.

RESUMOObjetivo: Analisar as alterações morfológicas do tálus após o tratamento cirúrgico do pé torto congênito pela técnica de McKay. Mé-todos: Foram analisadas, retrospectivamente, radiografias em perfil com carga dos pés de 14 pacientes com pé torto congênito unilateral submetidos ao tratamento pela técnica de McKay por dupla incisão. Todos os pacientes foram operados pelo mesmo cirurgião, com média de 6,53 anos entre a cirurgia e a radiografia. Comparamos as características do tálus dos pés operados com os parâmetros radiográfi-cos dos pés contralaterais. Avaliamos a presença de deformidade do dômus e da cabeça do tálus (avaliação da esfericidade), a altura e o comprimento do tálus, a presença e grau de subluxação do navicular, a alteração do ângulo de Gissane e o padrão do trabeculado ósseo. Resultados: Alterações da cabeça do tálus ocorreram em 92,8% dos casos; do dômus, em 92,8%; e do trabeculado, em 100%. A relação entre o comprimento do tálus do pé operado sobre o contralateral variou de 0,61 a 0,88 (média de 0,79; DP = 0,09), e da altura de 0,57 a 0,98 (média de 0,82; DP = 0,12). O ângulo de Gissane aumentou em todos os pés operados, e todos apresentaram subluxação do navicular, com índice variando de 6,43 a 59,75% (média de 26,34%; DP = 16,66%). Conclusões: Alterações talares ocorreram em 100% dos pés tratados pela técnica de McKay. Estabelecer parâmetros radiográficos para descrever e quantificar essas deformidades mostrou-se viável através de técnicas simples e de fácil execução. descritores -
