Abstract
Objective
This scoping review aims to summarize the current evidence related to SSS diagnosis and treatment to aid clinicians in managing the condition more effectively. Data Sources: PubMed, Medline, and Embase databases searched for studies related to SSS's etiology, diagnosis, or treatment. Study Selection: Databases were searched for available studies related to the etiology, diagnosis or treatment of SSS.
Study Design: A scoping review study design was selected to explore the breadth of knowledge in the literature regarding SSS diagnosis and treatment.
Data Extraction: Primary outcomes abstraction included accuracy of diagnostic tests, functional outcomes and pain relief associated with various non-operative and operative
treatment options for SSS.
Main Results: 1442 references were screened and 40 met inclusion criteria. Studies commonly reported SSS as a clinical diagnosis and relied heavily on a focused history and physical examination. The most common signs reported were medial scapular border tenderness, crepitus, and audible snapping. 3-Dimensional Computed Tomography (3D-CT) had high inter-rater reliability (IRR) of 0.972,1 with a 100% success rate in identifying symptomatic incongruity of the scapular articular surface. 38 Initial non-operative treatment was reported to be successful in most symptomatic patients, with an improved Visual Analogue Scale scores (7.7 ± 0.5 pre-treatment, to 2.4 ± 0.6 ). Persistently symptomatic patients underwent surgical intervention most commonly involving bursectomy, superomedial angle resection, or partial scapulectomy. High satisfaction rates of surgery were reported in VAS (6.9 ± 0.7 to 1.9 ± 0.9), ASES scores ( 50.3 ± 12.2 to 80.6 ± 14.9) and mean SST scores ( 5.6 ± 1.0 to 10.2 ± 1.1).
Conclusion
Focused history and physical examination is the most crucial initial step in the diagnostic process, with supplemental imaging used to assess for structural etiologies when non-operative management fails. Non-operative management is as effective as surgical management in pain relief and is advised for 3-6 months before operative treatment.
