中文摘要: |
【摘要】 目的:探讨不同上端融合椎对术前双肩水平的Lenke 1型青少年特发性脊柱侧凸(adolescent idiopath?鄄ic scoliosis,AIS)患者术后双肩平衡的影响。方法:选取2006年6月~2009年6月在我院行后路主胸弯融合术并有2年以上完整影像学随访资料的32例Lenke 1型AIS患者。所有患者术前均表现为双肩水平,其中男6例,女26例,手术时年龄13~19岁,平均14.9岁,上胸弯Cobb角平均为23.7°±8.0°(10°~36°),主胸弯Cobb角平均47.5°±6.9°(40°~62°)。按照上端融合椎不同将AIS患者分为两组:A组,上端融合椎为T3,19例;B组,上端融合椎为T4,13例。A组患者的手术时年龄、Risser征、上胸弯及主胸弯柔韧度与B组比较均无统计学差异(P>0.05)。采用方差分析比较两组患者术前、术后1年和末次随访时的上胸弯及主胸弯Cobb角、顶椎及躯干偏移距离、影像学肩关节高度差(radiographic shoulder height, RSH)、喙突高度差(CPH)和锁骨角(CA)。结果:A组随访时间2~4.5年,平均3.6±1.3年;B组随访时间2~4.8年,平均3.1±2.1年,两组比较无统计学差异(P>0.05)。术前、术后1年和末次随访时,A组患者的上胸弯Cobb角、主胸弯Cobb角、顶椎及躯干偏移距离、RSH、CPH及CA与B组比较均无统计学差异(P>0.05)。A、B两组患者术后1年和末次随访时的上胸弯Cobb角、主胸弯Cobb角、顶椎及躯干偏移距离、RSH、CPH、CA分别与术前比较均有显著性改善(P<0.05);末次随访时,两组患者的上胸弯Cobb角及RSH、CPH、CA较术后1年均显著减小(P<0.05),均获得较满意的双肩平衡。结论:对于术前双肩水平的Lenke 1型AIS患者,上端融合椎为T3或T4对重建术后双肩平衡的疗效无明显差别;对此类患者上端融合至T4即可获得良好的矫形效果和满意的双肩平衡。 |

【Abstract】 Objectives: To analyze the influence of upper fused vertebra on postoperative shoulder balance in Lenke type 1 adolescent idiopathic scoliosis(AIS) patients with preoperative leveled shoulders. Methods: A total of 32 Lenke type 1 AIS patients with preoperative leveled shoulders was included in the study. There were 6 boys and 26 girls with an average age of 14.9 years old(range, 13-19 years). The average preoperative proximal thoracic curve was 23.7°±8.0°(range 10°-36°), and the average preoperative main thoracic curve was 47.5°±6.9°(range 40°-62°). Thirty-two patients undergoing posterior thoracic fusion were divided into two groups: group A(n=19) included those who had a proximal fusion to T3; group 2(n=13) included those who had a proximal fusion to T4. There was no significant difference in demographics or baseline characteristics between group A and B including age at operation, Risser stage, flexibility of proximal and main thoracic (PT and MT) curves(P>0.05). Based on analysis of variance, radiographic parameters were compared among preoperation, 1 year follow-up and the final follow-up including PT and MT curve Cobb angle, apical vertebral translation(AVT), trunk shift, radiographic shoulder height(RSH), coracoids process height(CPH) and clavicle angle(CA). Results: In group A, the follow-up time ranged from 2 to 4.5 years with an average time of 3.6±1.3 years; while in group B, the follow-up time ranged from 2 to 4.8 years with a mean time of 3.1±2.1 years, which showed no difference between two groups(P>0.05). At preoperation, 1 year follow-up and the final follow-up, there were no significant differences in radiographic outcomes between group A and B including PT and MT curve Cobb angle, AVT, trunk shift, RSH, CPH and CA(P>0.05). For all patients, PT and MT curve Cobb angle, AVT, trunk shift, RSH, CPH and CA at 1 year follow-up and the final follow-up were both better than those before surgery(all P<0.05); while the values of RSH, CPH and CA at final follow-up were lower than those at 1 year follow-up(P<0.05). All patients obtained the balanced shoulders after surgery. Conclusion: For the Lenke type 1 AIS patient with leveled shoulder, proximal fusion to T4 can produce equivalent correction of scoliosis and shoulder balance. |
