Recurrent instability after revision anterior shoulder stabilization surgery

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Reconstructive Surgery

Background:

• Anterior shoulder instability often requires revision surgery when primary treatments fail.
• Various surgical techniques exist for revision anterior shoulder stabilization.
• The impact of bone defects on revision surgery outcomes is not well-defined.

Purpose of the Study:

• To systematically review and compare outcomes of different revision anterior stabilization techniques.
• To evaluate the influence of bone defects on the success of revision shoulder stabilization surgery.

Main Methods:

• Systematic review of PubMed, Cochrane, and Scopus databases (July 2012, March 2013).
• Analysis of 17 studies (Level I-IV Evidence) including 388 shoulders, adhering to PRISMA guidelines.
• Procedures categorized: arthroscopic Bankart repair, open Bankart repair, Bristow-Latarjet, and other open procedures. Recurrent instability defined as redislocation/resubluxation or positive apprehension post-revision.

Main Results:

• Open Bankart repair demonstrated the lowest recurrent instability rate (5.5%).
• Arthroscopic Bankart repair (14.7%) and Bristow-Latarjet (14.3%) showed similar, higher rates.
• "Other open procedures" exhibited the highest recurrent instability (42.7%).
• Inconsistent data on bone defects prevented definitive conclusions.

Conclusions:

• Significant variability exists in recurrent instability rates across different revision anterior shoulder stabilization procedures.
• Open Bankart repair appears most effective in reducing recurrent instability based on current evidence.
• Further research is needed to clarify the role of bone defects in revision surgery outcomes.
