In 4 patients with meningomyelocele and extension contracture of the knee (7 knees), a surgical operation is described to release the extension contracture and provide better sitting position with the knees flexed. This decreases the chance of fracture by reducing the lever arm of the lower extremity.
在4例患有脊髓脊膜膨出和膝关节伸直挛缩（7个膝关节）的患者中，描述了一种手术操作，以松解伸直挛缩并使膝关节屈曲从而提供更好的坐姿。通过缩短下肢的力臂，这降低了骨折的几率。
