目的:探讨早期后路半椎体切除治疗小儿非对称性半椎体畸形的效果。方法:采用后路半椎体切除治疗小儿非对称性半椎体畸形33例,随诊术后脊柱的生长发育、功能活动及X线摄片情况。结果:1例半椎体切除不全者残存的椎体继续生长,导致脊柱侧凸畸形加重48°,其余32例脊柱畸形有不同程度的减轻,脊柱的生长发育和功能活动正常。结论:早期后路半椎体切除是治疗小儿非对称性半椎体畸形的有效方法。
Objective: To investigate the effect of early posterior hemivertebra resection on asymmetric hemivertebra deformity in children. Methods: Thirty-three cases of hemivertebrae malformations were treated by posterior hemivertebra resection. The spine growth, function and radiography were followed up. Results: The remaining vertebral body continued to grow in one case with partial hemi-vertebral body excision. The scoliosis deformity was increased by 48 °. The remaining 32 cases suffered from spinal deformity were relieved to varying degrees. The spine growth and function were normal. Conclusion: Early posterior hemivertebra resection is an effective method to treat asymmetric hemivertebra deformity in children.
