研究了影响肋骨切除引起的脊柱侧凸严重程度的因素。 70只鸡根据治疗肋骨数量和手术年龄分为肋骨横断组和肋骨切除组共7个亚组，并进行放射学检查直至术后20周。肋骨横断组鸡在横断部位显示融合，并且没有明显的脊柱侧弯。在肋骨切除组中，切除的肋骨越多、手术年龄越小，脊柱侧凸就越严重。切除部位的骨再生使脊柱侧凸的进展变得更加温和。这些发现表明，肋骨切除时的年龄、手术肋骨的数量以及切除部位的骨不连在肋骨切除引起的脊柱侧弯的进展中起着重要作用。
Factors which affected the severity of scoliosis induced by rib resection were examined. Seventy chickens were divided into a rib transection group and a rib resection group with seven subgroups, according to the number of ribs treated and the age at surgery, and examined radiographically until 20 weeks postoperatively. Rib transection group chickens showed fusion at the transected site and no marked scoliosis. In the rib resection group, the more ribs resected and the younger the age at operation, the more severely the scoliosis developed. Bone regeneration at the resection site made the progression of scoliosis milder. These findings indicate that the age at rib resection, the number of ribs that are operated on, and nonunion of the resected sites play important roles in the progression of scoliosis induced by rib resection.
