[RESEARCH DEVELOPMENT OF REVERSE TOTAL SHOULDER ARTHROPLASTY]

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Reconstructive Surgery

Background:

• Reverse total shoulder arthroplasty (RTSA) is an evolving surgical technique.
• Its application addresses complex shoulder pathologies, particularly those involving irreparable rotator cuff tears.

Purpose of the Study:

• To review the development and clinical applications of RTSA.
• To analyze current literature on RTSA outcomes and complications.

Main Methods:

• Comprehensive literature review and analysis of publications on RTSA.
• Evaluation of clinical outcomes and identified complications.

Main Results:

• RTSA is indicated for pseudoparalysis due to irreparable rotator cuff tears with humeral head migration and deltoid function.
• Short-term results are generally satisfactory, but complications like scapular notching, instability, and limited rotation exist.
• Surgical considerations include approach selection, prosthetic rotation center, and bone grafting for defects.

Conclusions:

• The clinical use of RTSA is relatively recent, necessitating long-term outcome observation.
• Computer-assisted techniques hold potential for improving RTSA results.
