The purposes of this study were to determine the long-term correction achieved by excision of lumbar hemivertebrae and the risk attendant. Seven patients had a follow-up of 41.14 months for lumbar hemivertebral excisions. Six had two-stage anterior vertebral body excision and, 7-8 days later, posterior lamina and pedicle excision with fusion. One patient had a single-stage correction. After surgery, the patients were in pantaloon casts or braces for a minimum of 6 months (supine, first 6-12 weeks). Hemivertebrae were at L2 (N = 1), L3 (N = 1), L4-L5 (N = 1), and L5-S1 (N = 4). Preoperative curves or hemivertebral angles averaged 36.6 degrees (range, 30-52 degrees). Average age was 7.5 years (range, 22 months to 12.5 years). Mean follow-up was 41.14 months. Surgical correction of the seven cases averaged 28.0 degrees. Two-stage procedures yielded 29.7 degrees correction with no complications; single-stage yielded 18 degrees correction, and the only complication was an L5 nerve root paresis.
本研究的目的是确定腰椎半椎体切除所实现的长期矫正效果及伴随风险。7例患者接受了腰椎半椎体切除术后随访41.14个月。6例患者接受了两阶段前路椎体切除，7 - 8天后进行后路椎板和椎弓根切除并融合。1例患者接受了单阶段矫正。术后，患者佩戴连身石膏或支具至少6个月（最初6 - 12周仰卧）。半椎体位于L2（n = 1）、L3（n = 1）、L4 - L5（n = 1）和L5 - S1（n = 4）。术前侧弯或半椎体角度平均为36.6度（范围为30 - 52度）。平均年龄为7.5岁（范围为22个月至12.5岁）。平均随访时间为41.14个月。7例病例的手术矫正平均为28.0度。两阶段手术矫正29.7度，无并发症；单阶段手术矫正18度，唯一的并发症是L5神经根麻痹。
