To evaluate the results from surgical treatment of hip dislocation through the anteromedial approach, in patients with arthrogryposis multiplex congenita (AMC). Methods: The medical files and radiographs of seven children with AMC who presented hip dislocation (total of 10 dislocated hips) were retrospectively reviewed. Pre and postoperative joint mobility was evaluated by summing the joint range of motion in flexion and abduction. The acetabular angle and height of the femoral neck before the operation, and the continuity of the Shenton arc, Sharp angle and center-edge (CE) angle after the operation, were evaluated radiographically. When avascular necrosis was identified, it was classified in accordance with Ogden and Bucholz. Results: The mean age of the children at the time of the surgery was 5.5 months (range: 3 to 11 months). The mean duration of follow-up for the patients was 9.5 years (range: 2 to 13 years). The mean amplitude of the sum of the joint range of motion in flexion and abduction in the preoperative examination was 108° (range: 70° to 155°) and postoperatively, it was 125° (range: 75° to 175°). In the last evaluation, eight hips were found to be centered and two were subluxated. Two hips had been subjected to Salter iliac osteotomy. Two hips (20%) had presented significant signs of Ogden type IV avascular necrosis. Eight hips had good results while two were fair. Conclusion: We consider that the anteromedial approach is a good option for treating hip dislocation in very young patients with arthrogryposis multiplex congenita.
Objective: To present the deformities and evaluate the results of their treatment. Methods: Retrospective study of patients with deformity following surgical access to the spinal canal. Fifteen patients who met the inclusion criteria were included. Patients without complete data in medical records were excluded. Results: Fourteen patients underwent surgical treatment and one patient received conservative treatment with vest type TLSO. The average angle of kyphosis correction was 87° preoperatively to 38° postoperatively, while the associated scoliosis correction was 69° preoperatively to 23° postoperatively. Conclusions: The prevention of deformity should be emphasized to avoid laminectomy alone, while laminoplasty should be the procedure of choice for canal access in surgeries where there is no need for resection of the posterior elements.
OBJETIVO: Avaliar os resultados clínicos e radiográficos do tratamento cirúrgico da escoliose paralítica na mielomeningocele. MÉTODOS: Estudo retrospectivo mediante revisão de prontuários e radiografias dos pacientes portadores de mielomeningocele, tratados cirurgicamente entre os anos de 1999 e 2009. RESULTADOS: Foram analisados os prontuários e radiografias de 29 pacientes. A média de idade no momento da cirurgia foi de 12,2 anos, com um acompanhamento médio de 3,8 anos. O ângulo pré-operatório médio da escoliose de 77º foi inicialmente corrigido para 29º e, no final do seguimento deteriorou para 34º. A média da obliquidade pélvica foi de 16º, corrigida no pós-operatório imediato para 10º e, no pós-operatório tardio para 13º. A descompensação média do tronco foi de 117mm, inicialmente corrigida para 67mm e, no final do seguimento, deteriorou para 98 mm. CONCLUSÕES: Os pacientes no qual a instrumentação estendeu-se até a pelve, obtiveram melhores resultados em todas as mudanças relativas ao longo do tempo, quais sejam, escoliose, obliquidade pélvica e descompensação do tronco, com exceção da perda de correção da escoliose, que foi menor nos pacientes que não tiveram fixação da pelve.
