Biomechanics Analysis of Latissimus Dorsi Transfer in Reverse Shoulder Arthroplasty
نویسندگان
چکیده
Reverse total shoulder arthoplasty (RTSA) is commonly used in patients with cuff tear arthropathy (CTA) to relief pain and to restore active humeral elevation ROM [1]. The reverse prosthetic designs medialise the humeral centre of rotation increasing the Deltoid moment arm and its performance [2]. However, clinical studies have shown that patients with RTSA usually show poor humeral internal/external ROM [1]. Especially in the case of atrophy or fatty infiltration of the posterosuperior part of the RC, involving both infraspinatus and teres minor (TM), the RTSA fails to restore active external rotation [3]. Latissimus dorsi (LD) tendon transfer has been proposed as a solution to restore active external rotation in patients with massive and irreparable rotator cuff (RC) tears [4].

Combined latissimus dorsi and teres major tendon transfers for external rotation deficiency in reverse shoulder arthroplasty.
Treatment of rotator cuff deficient shoulders continues to evolve. Reverse total shoulder arthroplasty has proven effective for restoring forward elevation and abduction in patients who suffer from pseudoparalysis secondary to rotator cuff insufficiency. Unfortunately, reverse total shoulder arthroplasty is less effective at restoring lost external rotation function in patients with deficient p...
متن کاملTendon transfers for irreparable rotator cuff tears: An update
Shoulder dysfunction in the setting of irreparable rotator cuff tears (RCTs) can be treated successfully with different types of tendon transfer: Latissimus dorsi transfer for irreparable posterosuperior RCTs works best for young, active patients with an intact subscapularis, no pseudoparalysis or previous surgery, and a functioning teres minor.A more anatomical transfer for irreparable postero...
متن کاملReverse shoulder arthroplasty for deltoid-deficient shoulder following latissimus dorsi flap transfer. Case report
INTRODUCTION The usual indication for reverse shoulder arthroplasty is glenohumeral arthritis with inadequate rotator cuff and intact deltoid muscle. We report here a case of reverse shoulder arthroplasty using a lattisimus dorsi flap in a patient with deltoid-deficient shoulder following a gunshot injury. PRESENTATION OF THE CASE The patient was an otherwise healthy 51-year-old male with a h...
متن کاملRotator Cuff Reconstruction and Humeral Head Replacement Using Smaller Humeral Prostheses in Cuff Tear Arthropathy Patients under 70 Years of Age
Background: Most reverse shoulder arthroplasty (RSA) studies have shown good improvement in arm elevation without improvements in external rotation (ER). In addition, high rates of complications after long-term RSA have been reported, suggesting that RSA should be limited to elderly patients, especially those who are older than 70 years old. Since 2001, we have developed a strategy of rotator c...
متن کاملLong-term follow-up after latissimus dorsi transfer for irreparable posterosuperior rotator cuff tears.
BACKGROUND Irreparable posterosuperior rotator cuff tears are treated in several ways. Transfer of the latissimus dorsi is an alternative with acceptable mid-term results, but long-term results have rarely been published. METHODS The cases of 108 consecutive patients with 115 shoulders treated with latissimus dorsi transfer between 2000 and 2005 were reviewed clinically and radiographically. ...
