Purpose This study aimed to verify if the navigation system used in high tibial osteotomy (HTO) adds precision to the procedure regarding mechanical axis correction and prevention of tibial slope increases. Methods In this historically controlled study, patients with medial osteoarthrosis and genuvarum underwent HTO between 2004 and 2012; the first 20 were operated with the conventional technique, using pre-planning correction by the Dugdale method and 18 further patients were operated with the navigation system introduced in our hospital. Results The two groups were similar for pre-operative mechanical axis (mean 8.10±3.14 for the control and 6.60± 2.50 for the navigated group), pre-operative tibial slope (mean 8.95±3.47 versus 8.17±3.11, respectively) and Lyshom score (40.85±15.46 and 44.83±16.86). After surgery, the control group presented mean mechanical axis of 3.35±3.27, tibial slope of 13.75±3.75 and Lyshom score of 87.60±11.12. The navigated group showed a postoperative mechanical axis mean of 3.06±1.70, tibial slope of 10.11±0.18 and Lyshom score of 91.94±11.61. Conclusions The navigation system allowed a significantly better control of tibial slope. Patients operated with the navigation system had significantly better Lysholm scores.
Purpose To evaluate the safety and period of hospitalization of the treatment of femoral shaft fractures with titanium elastic nails (TEN) in the age range 5 to 14 years. The hypothesis was that TEN might be a low-cost treatment, with good clinical results and short length of hospitalization. Methods Thirty children with femur fractures were surgically treated with TEN. Results The patients spent an average of 9.4 days in hospital. The average period for the healing process was 7.7 weeks. Partial weight bearing was permitted 3.3 weeks after surgery. The incidence of overgrowth was 60%, with an average of 0.40 cm. Conclusions The surgical method brings few complications and results in good limb alignment, with a short period of hospitalization and early return to daily activities and school.
CONTEXT AND OBJECTIVE: Femoral fractures are common in children between 2 and 12 years of age, and 75% of the lesions affect the femoral shaft. Traction followed by a plaster cast is universally accepted as conservative treatment. However, in some situations, a surgical approach is recommended. The objective here was to compare treatments for femoral shaft fractures using intramedullary nails (titanium elastic nails, TEN) versus traction and plaster casts in children. The hypothesis was that TEN might provide better treatment, with good clinical results in comparison with plaster casts. DESIGN AND SETTING: This retrospective comparative study was conducted in a public university hospital. METHODS: Sixty children with femoral fractures were evaluated; 30 of them underwent surgical treatment with TEN and 30 were treated conservatively using plaster casts. The patients' ages ranged from 5 to 13 years (mean of 9 years).
RESULTS:The mean duration of hospitalization was nine days for the surgical group and 20 days for the conservative group. The incidence of overgrowth in the patients treated with TEN was 60.0% and, for those treated conservatively, 13.3%. Partial weight-bearing was allowed after 3.5 weeks in the surgical group and after 9.6 weeks in the conservative group. New hospitalization was required for 90.0% in the surgical group and 16.7% in the conservative group. Patients treated with plaster casts presented higher incidence of complications, such as loss of reduction. CONCLUSIONS: The surgical method presented better results for children.
RESUMO
CONTEXTO E OBJETIVO:Fraturas femorais são comuns em crianças entre 2 e 12 anos de idade, e 75% das lesões acometem a diáfise. Tração seguida de aparelho gessado ("gesso") é universalmente aceita como tratamento conservador. Entretanto, em algumas situações o tratamento cirúrgico é recomendado. O objetivo foi comparar o tratamento de fraturas diafisárias do fêmur com hastes intramedulares (titanium elastic nails, TEN) com tração e gesso em crianças. A hipótese era de que TEN pode ser melhor tratamento, com bons resultados clínicos em comparação com o gesso. TIPO DE ESTUDO E LOCAL: Este estudo retrospectivo e comparativo foi conduzido num hospital público universitário. MÉTODOS: Sessenta crianças com fraturas de fêmur foram avaliadas, 30 delas foram submetidas a tratamento cirúrgico com TEN e 30 foram tratadas de forma conservadora usando gesso. A idade dos pacientes variou de 5 a 13 anos (média de 9 anos). RESULTADOS: O tempo médio de internação foi de 9 dias para o grupo cirúrgico e 20 dias para o grupo conservador. A incidência de crescimento excessivo nos pacientes tratados com TEN foi de 60,0% e, para aqueles tratados de forma conservadora, 13,3%. Sustentação parcial de peso foi permitida após 3,5 semanas no grupo cirúrgico e após 9,6 semanas no grupo conservador. Houve 90,0% de novas internações no grupo cirúrgico e 16,7% no grupo conservador. Pacientes tratados com gesso apresentaram maior incidência de complicações, tais como perda de redução. CONCLUS...
Westin's tenodesis, with or without other associated procedures, can correct or improve the calcaneus and valgus ankle deformity in patients with myelomeningocele sequelae. There was no association of the surgical result with age at the time of surgery. There was no inversion of the deformity in equinus during the follow-up time.
