Arthroscopic-assisted latissimus dorsi transfer for massive rotator cuff tear: a systematic review.

Abstract

This systematic review provides a comprehensive description of different surgical techniques for massive rotator cuff tears (MRCTs) using arthroscopic-assisted latissimus dorsi transfer (A-LDT), reporting clinical outcomes and complications. We searched the literature on Medline (PubMed), Web of Science and Scopus databases using the combined keywords 'latissimus dorsi', 'tendon', 'transfer', 'rotator cuff tears', 'shoulder' and 'arthroscopy' to identify articles published in English, Spanish, French and Italian. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was followed for the manuscript selection. Ten studies (five retrospective and five prospective investigations), all published between 2014 and 2018, fulfilled our inclusion criteria, dealing with 348 (55.7% male) patients, with a mean age of 61.6 years (range 31-83). A-LDT is a technical demanding procedure. When compared with the open technique, it does not seem to provide significant subjective and objective clinical outcome improvements. A-LDT seems to yield lesser surgical complications and post-operative stiffness. Sparing the deltoid muscle belly could result in a more effective shoulder post-surgery function. Further comparative randomized controlled trials with longer follow-up are needed to clarify the potentially promising superiority of A-LDT.
