ABSTRACT
BACKGROUND:
Management of persistent symptomatic scapulothoracic abnormal motion (STAM) in the absence of periscapular muscle paralysis may be challenging. This study reports the outcomes of arthroscopic pectoralis minor release and scapulopexy for the management of symptomatic STAM secondary to pectoralis minor hyperactivity and serratus anterior hypoactivity in the absence of periscapular paralysis.METHODS:
This was a retrospective cohort study with prospectively collected data of patients with symptomatic STAM secondary to pectoralis minor hyperactivity and serratus anterior hypoactivity. Surgery was indicated if patients failed 6 months of conservative management. Patient outcomes were assessed with shoulder range of motion (ROM) measurements, numerical pain scale, shoulder subjective value (SSV), and Constant score. Data were analyzed with Fischer's exact test for categorical variables and Student's t-test of unequal variance for continuous and categorical variables.RESULTS:
Thirty-one consecutive patients were included in the study period between 2017 and 2020. Average age at the time of surgery was 24 years (range, 14-44 years), 80% of patients were female, and average follow-up after surgery was 23 months (range, 15-39 months). Thirteen patients also had a diagnosis of recurrent posterior instability. At final follow-up, 81% reported significant improvements in their STAM, as demonstrated by improved mean pain scale, ROM, SSV, and Constant scores. Pain improved from 6 (range, 4-10) to 2 (range, 1-4), SSV from 30% (range, 10%-40%) to 75% (range, 60%-100%), and Constant score from 49 (range, 43-61) preoperatively to 79 (range, 51-100) postoperatively (P < .01). All 13 patients with recurrent associated posterior instability had resolution of their instability. Flexion ROM improved from average 100° (range, 60°-150°) to 140° (range, 120°-160°). One patient had traumatic rupture of her scapulopexy 7 weeks postoperatively and underwent revision scapulopexy. Thirteen percent had minimal improvement after surgery and experienced recurrence 3 months postoperatively.CONCLUSION:
In patients with symptomatic STAM secondary to pectoralis minor hyperactivity and serratus anterior hypoactivity, arthroscopic pectoralis minor release and scapulopexy is an effective surgical option.Palavras-chave
