Outcomes after arthroscopic scapulothoracic bursectomy for the treatment of symptomatic snapping scapula syndrome

BACKGROUND: The purpose of our study was to examine the clinical outcomes after arthroscopic scapulothoracic bursectomy for the treatment of scapulothoracic bursitis at a minimum of 2-year follow-up. METHODS: Twenty patients who underwent arthroscopic scapulothoracic bursectomy for the treatment of symptomatic snapping scapula syndrome were identified from a single surgeon’s database. Patients were indicated for surgery if their symptoms persisted for more than 6 months and if they failed nonoperative treatment. Acquired data included patient demographics, shoulder range of motion, American Shoulder and Elbow Surgeon score, visual analog scale scores for pain, and the following Patient-Reported Outcomes Measurement Information System scores: Upper Extremity Computer Adaptive Test Version 2.0, pain intensity, and pain interference scores. Patient satisfaction and subjective shoulder value were also recorded out of 100. Fisher's test and unpaired t tests were performed for statistical analysis, and P values <.05 were considered significant. RESULTS: A total of 20 patients (24 scapulae) were included in our study, with an average follow-up period of 44 (range: 27-91) months. The mean postoperative Patient-Reported Outcomes Measurement Information System scores for Upper Extremity Computer Adaptive Test Version 2.0, pain interference, and pain intensity were 44.2 ± 10.7, 50.9 ± 9.5, and 42.1 ± 9.5, respectively. The mean postoperative American Shoulder and Elbow Surgeon score was 79.0 ± 21.5, and the mean subjective shoulder value was 82.7 ± 12.9. Visual analog scale pain levels showed a significant decrease from 4.95 ± 2.26 preoperatively to 2.27 ± 2.7 (P < .05) postoperatively. There was no significant difference in shoulder range of motion after surgery. The mean patient satisfaction was 72.9, with 65% (13/20) of patients reporting satisfaction levels ≥ 80%. Two patients did not report the resolution of their symptoms and required revision surgery. CONCLUSION: Arthroscopic treatment of scapulothoracic bursitis is a safe, reliable technique that is effective in providing symptomatic relief with a low rate of recurrence, with most patients reporting a significant reduction in periscapular pain.
