High incidence of complications associated with shoulder girdle reconstruction utilizing a Stryker proximal humerus cap endoprosthesis following Tikhoff-Linberg resections

Abstract: Introduction The Tikhoff-Linberg procedure is a limb salvage technique for tumours of the shoulder girdle which preserves function of the hand and elbow; however, shoulder function is limited. A humeral cap endoprosthesis (Stryker Orthopedics, Mahwah, NJ, USA) was developed within the Modular Replacement System (MRS) to act as a functional spacer for these defects; however, the outcomes of this implant have not been described. Methods Thirty-three (17 male, 16 female) patients underwent a Tikhoff-Linberg proce… Show more

“…The lateral elevation and forward flexion ranges in the prosthetic replacement group were lower than those in the shoulder arthrodesis group. No more than 30 • abduction and 45 • forward flexion could be achieved in prosthesis cases in the present study and in most published studies [15][16][17].…”

“…Moreover, the engineered porosity (if substantial) reduces device’s elastic modulus, which has been suggested to result in enhanced osteogenesis and reduced stress shielding of the periprosthetic bone ( Huiskes et al, 1992 ; Sumner and Galante, 1992 ; Nouri and Hodgson, 2010 ; Moghaddam et al, 2016 ; Caffrey et al, 2018 ). Stress shielding is a common complication of endoprosthetic reconstruction surgery and is significant not only because of associated surgical failure, but also due to the resulting periprosthetic osteopenia, which significantly limits future treatment options ( Nagels et al, 2003 ; Tagliero et al, 2020 ; Braig et al, 2021 ; Cho et al, 2021 ; Bendich et al, 2022 ). Selecting an appropriate prosthesis modulus is crucial to achieving the best possible functional and long-term outcomes for patients with medical implants because it ensures that the mechanical properties of the artificial implant closely match those of the surrounding natural tissues and bones, preventing issues like stress shielding and subsequent implant loosening, or implant failure that may arise if the prosthesis is too rigid or too flexible compared to the natural tissue.…”

“…This is a historical series in a reference center for bone and soft tissue cancers, including exclusively scapulectomies, which explains the small number of patients. On the other hand, this is a homogeneous monocentric study using a single method, namely scapulectomy without reconstruction by prosthesis 20 , 26 , 28 , 29 or by allograft 32 of the scapula. This approach was justified by the fact that each of the patients included in this series required extensive soft tissue resection, most often involving the rotator cuff muscles, deltoid, trapezius, latissimus dorsi, and rhomboids muscle.…”
