Two children with spastic quadriplegia who developed excessive lumbar lordosis after selective dorsal rhizotomy are described. The rhizotomy did not change the ambulatory status of either child (one nonambulator, one household ambulator). Preservation of unopposed hip flexion in the presence of multiple laminectomies may lead to the development of a lordotic deformity in children who sit most of the time. Excessive lumbar lordosis may cause pain and difficulty in sitting. Surgical correction of this deformity is complex because of the removal of posterior elements during the rhizotomy.
本文描述了两名痉挛性四肢瘫痪儿童，他们在选择性脊神经后根切断术后出现了过度腰椎前凸。脊神经后根切断术并未改变两名儿童的行走状态（一名不能行走，一名在家中能行走）。在进行多次椎板切除术后，保留无对抗的髋关节屈曲可能会导致大部分时间坐着的儿童出现脊柱前凸畸形。过度的腰椎前凸可能会引起疼痛和坐位困难。由于在脊神经后根切断术中切除了后部结构，这种畸形的手术矫正很复杂。
