Lesser Tuberosity Osteotomy in Anatomic Total Shoulder Arthroplasty

Effect of lesser tuberosity osteotomy size and repair construct during total shoulder arthroplasty.

BACKGROUND Lesser tuberosity osteotomy has been shown to decrease postoperative subscapularis dysfunction. The purpose of this study was to determine the effect of osteotomy thickness and suture configuration on repair integrity. MATERIALS AND METHODS One side of 12 matched-pair cadaveric shoulders was randomly assigned to either a thick osteotomy (100% of lesser tuberosity height) or a thin ...

Failure of Anatomic Total Shoulder Arthroplasty with Revision to Another Anatomic Total Shoulder Arthroplasty

Background: While outcomes of primary anatomic total shoulder arthroplasty (aTSA) are generally favorable, resultsafter revision procedures are less reliable. This study examines the functional outcomes, complications, and implantsurvival in patients who underwent revision of aTSA to aTSA.Methods: Patients who underwent revision aTSA were identified from 2008-2015. Demographic, clinical, surgic...

Repair Technique in Total Shoulder Arthroplasty Biomechanical and Clinical Evaluation of a Novel Lesser Tuberosity

Bilateral anatomic total shoulder arthroplasty versus reverse shoulder arthroplasty.

The results of anatomic total shoulder arthroplasty and reverse shoulder arthroplasty have previously been reported separately. Although the indications differ, scenarios exist in which a patient may have a total shoulder arthroplasty on 1 shoulder and a reverse shoulder arthroplasty on the contralateral shoulder.Between 1992 and 2009, twelve patients underwent bilateral sequential primary shou...

Analysis of subscapularis integrity and function after lesser tuberosity osteotomy versus subscapularis tenotomy in total shoulder arthroplasty using ultrasound and validated clinical outcome measures.

BACKGROUND The optimal method-subscapularis peel (SP) or lesser tuberosity osteotomy (LTO)-for takedown of the subscapularis during total shoulder arthroplasty (TSA) is controversial. This study compares the functional outcomes in a 2-surgeon cohort using the 2 techniques. METHODS Patients who underwent TSA with a minimum 1 year of follow-up were evaluated. Physical and ultrasound examination...
