Comparing outcomes of the anterosuperior and deltopectoral approaches in reverse total shoulder arthroplasty for degenerative glenohumeral arthritis: a systematic review.

PURPOSE

Reverse total shoulder replacement (rTSR) improves pain and function in patients with a wide range of shoulder pathology. Anterosuperior (AS) and deltopectoral (DP) approaches are widely used to gain access to the glenohumeral joint in arthroplasty. Our aim was to systematically review the literature comparing outcomes of these two approaches when performing rTSR for degenerative glenohumeral arthritis.

METHODS

Systematic review was performed with an electronic multi-database search (Pubmed, Medline & Embase) according to PRISMA guidelines on 18th September 2022. Data from published studies of any study design that met the inclusion criteria were extracted, reviewed and synthesized.

RESULTS

A total of 38 studies were identified for full text review, of which four were included. No significant difference in pain and range of motion were observed between approaches. Scapular notching was more common in the anterosuperior approach. Low rates of instability and intra-operative fracture were observed in both.

CONCLUSION

Both approaches demonstrate similar clinical outcomes with reference to pain, range of motion and complications when performing rTSR indicated for degenerative joint disease. However, further well-designed studies are required.
