The purpose of this study was to correlate the bone block graft position, its dimension, its reabsorption and its integration with clinical outcome in patients operated on for recurrent anterior shoulder instability.
Twenty-four patients affected by recurrent anterior shoulder dislocation and operated on using the Latarjet procedure were enrolled in this study. At 6 and 24 months, patients were evaluated with the following scales: ROWE, WOSI, Oxford instability score, UCLA, DASH and Constant score. Patients underwent two postoperative CT scans: immediately after surgery (T0) and at 24 months post-op (T1).
At 24 months, none of the 24 patients reported further episodes of dislocation. Clinically at the final follow-up, we found excellent results in all the evaluation scales. Mean reduction in bone graft from T0 to T1 was 42% of the overall volume; similarly reduction in the overall surface was 29.3%; decrease in length, width and depth was, respectively, 3.4, 2.2 and 1.0 mm; all these parameters decreased significantly (p < 0.05). No correlations were found between radiological parameters and clinical and functional outcomes.
The results confirm that a lack of integration or a significant reabsorption of the graft is present in the Latarjet procedure, but they do not significantly affect the clinical and functional results.
本研究的目的是将复发性前肩不稳患者手术中骨块移植的位置、尺寸、再吸收情况及其整合与临床结果相关联。
本研究纳入了24例因复发性前肩脱位接受Latarjet手术的患者。在术后6个月和24个月时，使用以下量表对患者进行评估：ROWE、WOSI、牛津不稳评分、UCLA、DASH和Constant评分。患者术后接受两次CT扫描：术后即刻（T0）和术后24个月（T1）。
在24个月时，24例患者均未报告再有脱位发作。在最终随访时的临床评估中，我们在所有评估量表上均发现了优异的结果。从T0到T1，骨移植的总体积平均减少了42%；同样，总表面积减少了29.3%；长度、宽度和深度分别减少了3.4、2.2和1.0毫米；所有这些参数均显著下降（p<0.05）。未发现放射学参数与临床和功能结果之间存在相关性。
结果证实，Latarjet手术中存在移植骨整合不良或明显再吸收的情况，但它们并未显著影响临床和功能结果。
