Abstract:Objective To investigate the clinical feasibility of infraspinatus tendon fixation in the treatment of anterior instability of shoulder joint with kissing injury. Methods The clinical data of 80 patients with anterior instability of shoulder joint with kissing injury in our hospital from January 2013 to January 2017 were retrospectively analyzed. These patients were divided into two groups including a labral repair combined with infraspinatus tendon fixation under arthroscope group (combined surgery group, n = 40) and a simple glenoidal labrum repair under arthroscope group (single surgery group, n = 40) according to the treatment methods. The ranges of external rotation and internal rotation of the shoulder joint at neutral position, OSIS scores, ROWE scores and clinical efficacy of the two groups were statistically analyzed. Results The OSIS score of the patients in the combined surgery group was lower than that in the single surgery group (P < 0.05), while the ROWE score was higher than that in the single surgery group (P < 0.05). The excellent rate of treatment in the combined surgery group was higher than that in the single surgery group (P < 0.05). Conclusions Infraspinatus tendon fixation is highly feasible in the treatment of anterior instability of shoulder joint with kissing injury, so is worthy of promotion and use in the clinic.
