107 patients with separation of the head of the femoral epiphysis were treated surgically at the Marburg Orthopaedic University Hospital during the 1955--1975 period. Followup examinations were performed in 69 patients. 34 of these had been subjected to subcapital linear osteotomy. On the average the operation had been performed 7.64 years ago. Early results were good. In most cases it was possible to correct the malposition caused by the slipping. Necroses of the femoral head were not seen more frequently than with most other methods. Necrosis of the femoral head occurred four times after 35 linear osteotomies in 34 patients. Definite roentgenological signs of arthrosis were seen about 2--3 years after the opration. These changes increased with increasing interval between operation and examination. Subcapital linear osteotomy cannot prevent the development of early arthrosis in cases where separation of the head of the femoral epiphysis exceeds 30 degrees. Despite this limitation, the patients examined during the followup study revealed a clinically favourable picture with good functioning and very considerable freedom from symptoms; it must be borne in mind in this connection that all patients were still under 35 years of age.
1955年至1975年间，马尔堡大学骨科医院对107例股骨头骨骺分离患者进行了手术治疗。对其中69例患者进行了随访检查。其中34例接受了股骨颈线性截骨术。平均手术时间为7.64年前。早期效果良好。在大多数情况下，可以纠正由滑脱引起的畸形。股骨头坏死的发生率并不比大多数其他方法更高。34例患者行35次线性截骨术后，有4例发生股骨头坏死。术后约2至3年可见明确的关节病X线征象。这些变化随着手术与检查间隔时间的增加而加重。当股骨头骨骺分离超过30度时，股骨颈线性截骨术无法预防早期关节病的发生。尽管有此局限性，但随访研究中的患者在临床上呈现出功能良好、症状显著减轻的有利情况；在此必须牢记，所有患者年龄均未满35岁。
