The purpose of this study is to evaluate the magnetic resonance imaging (MRI) following Putti-Platt procedure for recurrent anterior dislocation of the shoulder. Six shoulders of six patients who had received Putti-Platt procedure were evaluated by the MRI before and after operation. After the Putti-Platt procedure the subscapularis tendon was thickened and an increased signal area on T2-weighted images were observed in four patients. The area of subscapularis tendons after operation was increased maximally 3.46-fold and the volume was increased on average 1.51-fold. The course of subscapularis muscle fiber before operation was described as a mild arc, but changed to a straight line after the procedure in five patients. The findings in this study suggest that the Putti-Platt procedure leads to a remarkable increase in strength of subscapularis tendon and an improvement of laxity of subscapularis muscle. In conclusion, there is a good possibility that this procedure will increase the stability of the glenohumeral joint and be a successful treatment for recurrent anterior dislocation of the shoulder.
本研究的目的是评估普蒂-普拉特手术治疗复发性肩关节前脱位后的磁共振成像（MRI）表现。对6例接受普蒂-普拉特手术的患者的6个肩关节进行了术前和术后的MRI评估。普蒂-普拉特手术后，4例患者的肩胛下肌腱增厚，T2加权图像上出现信号增强区域。术后肩胛下肌腱面积最大增加3.46倍，体积平均增加1.51倍。5例患者术前肩胛下肌纤维走行呈轻度弧形，术后变为直线。本研究结果表明，普蒂-普拉特手术可显著增强肩胛下肌腱的强度，改善肩胛下肌的松弛度。总之，该手术很有可能增加盂肱关节的稳定性，成为治疗复发性肩关节前脱位的成功方法。
