STUDY DESIGN
Retrospective chart and radiographic reviews were conducted.
OBJECTIVE
To identify the incidence of and any possible risk factors for the crankshaft phenomenon after posterior spinal arthrodesis for congenital scoliosis.
SUMMARY OF BACKGROUND DATA
Studies have shown the crankshaft problem to be common after posterior arthrodesis for infantile and juvenile idiopathic scoliosis, but the few reports available show it to be much less common for congenital scoliosis.
METHODS
This study chose children fused before the pubertal growth spurt, all classified as Risser 0 and with open triradiate cartilages. These children were followed to the end of their growth (mean follow-up period 12 years). Several measurement parameters were used for evaluation.
RESULTS
The crankshaft problem, measured as a Cobb angle increase of more than 10 degrees, was seen in 15% of the 54 patients. There was a positive correlation with earlier surgery and larger (>50 degrees) curves. No other positive correlations could be identified.
CONCLUSIONS
Crankshafting was observed in 15% of the patients, more often with larger curves and earlier fusions.
研究设计
进行回顾性图表和影像学评估。
目的
确定先天性脊柱侧弯后路脊柱融合术后曲轴现象的发生率及任何可能的危险因素。
背景资料总结
研究表明，在婴儿型和青少年特发性脊柱侧弯后路融合术后曲轴问题很常见，但现有少数报告显示其在先天性脊柱侧弯中不太常见。
方法
本研究选取青春期生长突增前接受融合手术的儿童，均为Risser 0级且三骺软骨开放。对这些儿童进行随访直至生长结束（平均随访期12年）。使用多个测量参数进行评估。
结果
在54例患者中，15%出现曲轴问题，以Cobb角增加超过10度为衡量标准。与手术时间早和侧弯度数大（>50度）呈正相关。未发现其他正相关因素。
结论
15%的患者出现曲轴现象，更多见于侧弯度数大及融合时间早的情况。
