Thirty-two biplane osteotomies in thirty patients were performed for the treatment of chronic slipped capital femoral epiphysis during a fourteen-year period at the Jersey City Medical Center. Twenty-seven patients (twenty-nine hips) were followed for two and a half to fourteen years. The correction obtained at surgery was maintained in all of the patients. Although two patients had had narrowing of the hip joint preoperatively and one had narrowing postoperatively, this had resolved at an average of three years postoperatively. Improvement in the range of motion was noted. In twenty patients the limb lengths were equal, in three the involved limb was longer, and in four patients the limb was shorter postoperatively. One patient had a slight subluxation of the femoral head due to an excessive valgus correction at the time of surgery, and one patient had delayed union of the osteotomy site which went on to satisfactory healing. No patients had avascular necrosis of the femoral head or symptoms of degenerative arthritis at follow-up. Preoperative joint-space narrowing did not appear to be a contraindication to this procedure.
在泽西城医疗中心的十四年期间，对30例患者实施了32例双平面截骨术，用于治疗慢性股骨头骨骺滑脱。27例患者（29髋）随访了2.5至14年。所有患者手术时获得的矫正得以维持。尽管有2例患者术前髋关节间隙变窄，1例术后变窄，但平均在术后3年时已缓解。观察到活动范围有所改善。20例患者肢体长度相等，3例患侧肢体变长，4例患者术后肢体变短。1例患者因手术时外翻矫正过度导致股骨头轻度半脱位，1例患者截骨部位延迟愈合，但最终愈合良好。随访时无患者发生股骨头缺血性坏死或退行性关节炎症状。术前关节间隙变窄似乎并非该手术的禁忌证。
