METHODS: This retrospective study was conducted from April 2018 to May 2022. Twenty-two patients with chronic scapholunate dissociation were treated using the IB augmentation technique, of whom 17 were followed-up for at least 1 year. Radiological results, including scapholunate distance, scapholunate angle, and radioscaphoid angle, were collected. Furthermore, clinical parameters, such as the visual analog scale (preoperative and at final follow-up), the Disabilities of the Arm, Shoulder, and Hand scores (preoperatively and at 3, 6, and 12 months postoperatively), and Mayo wrist scores (preoperative and at final follow-up), were measured.
RESULTS: The scapholunate distance increased significantly in the affected wrist compared to the unaffected wrist, which improved after reconstruction in all wrist positions ( P < 0.05). Compared to the unaffected wrist, the scapholunate angle increased significantly in all positions ( P < 0.05) except for extension ( P = 0.535) and improved after reconstruction in all wrist positions. The radioscaphoid angle significantly increased compared to the angle of the unaffected wrist in all positions ( P < 0.05) except for extension ( P = 0.602) and clenched fist ( P = 0.556). This angle improved after reconstruction in all wrist positions except for extension ( P = 0.900). The visual analog scale score (7-2, preoperatively and at final follow-up) and Mayo wrist score (53-82, preoperatively and at final follow-up) improved after surgery. The Disabilities of the Arm, Shoulder, and Hand scores also improved after surgery (68, 53, 30, 7, preoperatively and at 3, 6, and 12 months postoperatively).
CONCLUSIONS: This study revealed that scapholunate ligament reconstruction using an autologous tendon and suture tape is a good reconstruction technique that can improve clinical symptoms and radiographic parameters with a shorter operation time and fewer complications than other reconstruction methods.
方法:这项回顾性研究于2018年4月至2022年5月进行。使用IB增强技术治疗了22例慢性肩胛骨游离的患者,其中17人随访至少1年。放射学结果,包括肩胛骨距离,肩胛骨角,和辐射计角度,被收集。此外,临床参数,如视觉模拟量表(术前和最终随访时),手臂的残疾,肩膀,和手部评分(术前和术后3、6和12个月),和Mayo腕部评分(术前和最终随访时),被测量。
结果:与未受影响的手腕相比,受影响的手腕中的肩胛骨距离显着增加,在所有腕部位置重建后改善(P<0.05)。与未受影响的手腕相比,除伸张外(P=0.535),所有位置的肩胛骨角都显着增加(P<0.05),并且在所有腕部位置重建后都有所改善。除伸展(P=0.602)和握紧拳头(P=0.556)外,所有位置的放射性舟骨角度均显着增加(P<0.05)。除了伸展外,在所有手腕位置重建后,该角度都得到了改善(P=0.900)。术后视觉模拟量表评分(7-2,术前和最终随访)和Mayo腕部评分(53-82,术前和最终随访)改善。手臂的残疾,肩膀,手术后Hand评分也有所改善(68,53,30,7,术前和术后3,6和12个月).
结论:这项研究表明,使用自体肌腱和缝合带重建肩胛骨韧带是一种良好的重建技术,可以改善临床症状和影像学参数,与其他重建方法相比,手术时间短,并发症少。
