To analyse the risk factors of heterotopic ossification after spinal cord injury.
Of 104 patients with spinal cord injury, 47 (45.2%) were complicated by heterotopic ossification of the hip. These patients with heterotopic ossification were compared with 57 patients without heterotopic ossification.
Statistical analysis showed that complete paraplegia, spasticity and pressure sore were significantly (P < 0.05) or highly significantly (P < 0.01) related to heterotopic ossification formation. The coexistence of two or three of these factors in the paraplegic patients was found to significantly (P < 0.01) enhance the risk of heterotopic ossification formation.
When the spinal cord injured patients have single or multiple risk factors, they should be predicted for susceptibility of heterotopic ossification.
分析脊髓损伤后异位骨化的危险因素。
104例脊髓损伤患者中，47例（45.2%）并发髋关节异位骨化。将这些发生异位骨化的患者与57例未发生异位骨化的患者进行比较。
统计分析表明，完全性截瘫、痉挛和压疮与异位骨化形成显著相关（P<0.05）或高度显著相关（P<0.01）。发现截瘫患者中存在两种或三种这些因素会显著（P<0.01）增加异位骨化形成的风险。
脊髓损伤患者存在单一或多个危险因素时，应预测其发生异位骨化的易感性。
