目的：探讨青少年特发性脊柱侧凸（AIS）手术患者胸廓成形术后肋骨再生情况，比较男女性患者间肋骨再生差异。方法：1999年至2004年我院共行脊柱矫形内固定融合术及胸廓成形术治疗66例AIS患者，其中女性患者43例。平均年龄15．62岁，平均Cobb角58．86°；男性患者23例，平均年龄16．83岁，平均Cobb角60．87°。术后3个月、6个月、1年、2年摄全脊柱正侧位片复诊时应用Philips等提出的肋骨再生分级标准对患者肋骨再生情况进行评估。结果：术后3个月复诊60例患者，225根部分切除的肋骨中31．6％处于再生4级，52．9％处于5级：术后6个月复诊29例患者，107根部分切除的肋骨中79.4％处于再生5-6级；术后1年复诊32例患者，121根部分切除的肋骨中90．1％处于再生5-6级；术后1年内未见肋骨再生达到7级；术后2年复诊22例患者，79根部分切除的肋骨中98．7％处于再生5～7级，其中有4根肋骨（5．1％）达到7级。男女患者间肋骨再生分级未见明显差异。结论：AIS患者胸廓成形术后肋骨再生可分为2期，即肋骨形成期和塑形改建期．肋骨形成期在术后6个月基本完成，塑形改建期则持续时间较长；肋骨再生没有性别差异。

英文摘要：

Objective：To evaluate the rib regeneration in patients with adolescent idiopathic seoliosis （AIS） after thoraeoplasty and compare the results associated with sex.Method：66 patients with AIS and rib hump underwent instrumentation and thoraeoplasty from 1999 to 201M.Of these eases,there were 43 girls with the mean age of 15.62 years old and mean Cobb＇s angle of 58.86~ and 23 boys with the mean age of 16.83 years old and the mean Cobb＇s angle of 60.87~.The standing long-eaasette anteroposterior and lateral radiographs of spine were taken at 3th months,6th months,lth year and 2th years respectively after surgery.Rib regeneration classification established by Philips was used to analyze the rib formation of each patient.Result： Among 225 ribs from 60 patients,31.6% rib regeneration reached grade 4 and 52.9% reached grade 5 at 3th months follow-up.Among 107 ribs from 29 patients,79.4% ribs regeneration reached grade 5 or 6 at 6th months follow-up.Among 121 ribs from 32 patients,90.1% ribs regeneration reached grade 5 or 6 at lth year follow-up.Among 107 ribs from 22 patients,98.7% ribs regeneration reached grade 5 or 6 at 2th year followup.No fib regeneration reached grade 7 within 1 year and 4 ribs regenerated to grade 7 at 2th year followup.There was no difference between male and female patients.Conclusion： Rib regeneration can be divided into 2 phases,rib formation phase and rib reconstruction phase.Rib formation phase complete within 6 months while rib reconstruction phase may take much more time.
