Abstract:
Objective To study the preliminary effect of sartorius iliac flap in repair of acetabulum defect for developmental dysplasia of the hip (DDH) in elder children.Methods We retrospectively studied 17 elder children with acetabulum defect in DDH at the age＞6 years old who received acetabular repair with sartorius bone flap in this hospital from 2014 to 2016.All patients with acetabulum defect in DDH were treated with open reduction in general anesthesia.Three-dimensional osteotomy under the femur rotor was conducted to correct the femoral anteversion and neck-shaft angle.According to the height of femoral head dislocation lines,femur tuberosity was shorten and fixied with steel plates,joint capsule was reconstructed,The iliac sartorius musculocutaneous flap was took to the upper edge of the acetabular to repair the acetabular defect.The lower extremities were treated with plaster for 6 to 8 weeks after surgery.The hip joint function was trained and the function was evaluated with Mckay's criteria.The hip joint morphological evaluation was performed with reference to Severin's X-ray standard.Results Seventeen patients were followed up for 6 to 29 months.Postoperative reduction of the femoral head was good,the head mortar inclusive was satisfactory;there were no wound infection and femoral head necrosis.According to Mckay's criteria,2 patients got excellent,13 good,and 2 fair,with the fineness ratio at 88.2％;According to Severin's critera:11 patients excellent.Conclusion The overturned sartorius iliac flap can repair acetabulum defect,promote bone healing,and effectively improve acetabulum to cover head of femur.
