Two Double Sliding Rows: A New Technique for Stable Fixation of Lesser Tuberosity Osteotomy After Shoulder Resurfacing Arthroplasty, 2-Year Follow-up

The aim of the work is to describe a new technique, Two Double Sliding Rows (TDSR), for lesser tuberosity osteotomy fixation in shoulder resurfacing or stemless arthroplasties. Thirty shoulders were treated with TDSR. Lesser tuberosity osteotomy fixation was performed with 4 Corkscrew double-loaded suture anchors, implanted 2 medially and 2 laterally to the osteotomy. Assessment at 2-year follow-up included Constant and Murley score, Simple Shoulder Test, and physical examination focused on the subscapularis. Imaging included conventional radiography, computed tomography and ultrasound to assess healing of the osteotomy site, and changes in the subscapularis. The osteotomy healed in an anatomic position. No oversize of the humeral prosthetic component was found. Two subscapularis failures were detected clinically and confirmed by ultrasound. Subscapularis fatty infiltration increased in 14 cases by maximum 1 Goutallier stages; the increase was correlated with the preoperative rigidity level. TDSR allowed an immediate mobilization without preventing bone healing when resurfacing or stemless prostheses were implanted.
