In 15 patients with cerebral palsy who underwent selective posterior rhizotomy (SPR) and subsequent proximal femoral varus derotation osteotomy (VDO), heterotopic ossification (HO) around the hip after VDO was noted in four of eight patients with spastic quadriplegia (seven of 26 hips, 27%). HO was not noted in the seven patients with spastic diplegia. A radiographic review of 118 hips with a femoral VDO in the 69 patients with cerebral palsy who did not undergo SPR during the same period showed no HO. Frequent evaluation of postrhizotomy patients with cerebral palsy quadriplegia after a femoral VDO is necessary to recognize HO as a possible etiology for late-onset pain and limited hip range of motion (ROM).
在15例接受选择性后根切断术（SPR）及随后近端股骨内翻旋转截骨术（VDO）的脑瘫患者中，8例痉挛性四肢瘫患者中有4例（26个髋关节中的7个，27%）在VDO术后出现髋关节周围异位骨化（HO）。7例痉挛性双瘫患者未出现HO。对同期69例未接受SPR的脑瘫患者中118例接受股骨VDO的髋关节进行影像学检查，未发现HO。对接受VDO的脑瘫四肢瘫患者进行后根切断术后频繁评估，对于将HO识别为迟发性疼痛和髋关节活动范围（ROM）受限的可能病因很有必要。
