| Abstract |
PURPOSE
Our goal of this study was to compare the mechanism of injury and the clinical outcomes between the non-traumatic and traumatic type II SLAP lesions.
MATERIALS AND METHODS: From January 2007 to May 2009, the sunjects of this study were 27 patients who had undergone operations for isolated type II SLAP lesions. The lesions were classified according to Burkhart's method. The lesions that were located on the anterior-superior labrum were classified as type I, those lesions located on the posterior-superior labrum were classified as type II and those lesions located on the anterior-posterior labrum were classified as type III. The clinical outcomes were evaluated by the UCLA score and the KSS score preoperatively and postoperatively.
RESULTS
Of the 27 cases, 16 cases were traumatic and eleven cases were non-traumatic. In the traumatic group, there were 12, 2 and 2 cases of type I, type II and type III, respectively (p=0.013). In non-traumatic group, there were 2, 6 and 3 cases of type I, type II and type III (p=0.026). Anterior lesions were more frequent in the traumatic group and posterior lesions were more frequent in the non-traumatic group. For the clinical outcomes, the mean preoperative UCLA score and KSS score were 18 (range: 14~23) and 48 (range: 32~76), respectively, and the postoperative UCLA score and KSS score were 32 (range: 28~33) and 86 (range: 71~92), respectively, in the traumatic group, and the preoperative UCLA score and KSS score were 21 (18~25) and 58 (41~68), respectively, and the postoperative UCLA score and KSS score were 29 (26~31) and 81 (68~89), respectively in the non-traumatic group. There was no significant statistical difference of clinical outcomes between the two groups (p=0.317, 0.405).
CONCLUSION
In this study, the anatomical feature of type II SLAP lesion was associated with a trauma mechanism. Therefore, a trauma mechanism must be considered when planning the surgical treatment for type II SLAP lesions. |
