Aims Shoulder arthroplasty using short humeral components is becoming increasingly popular. Some such components have been associated with relatively high rates of adverse radiological findings. The aim of this retrospective review was to evaluate the radiological humeral bone changes and mechanical failure rates with implantation of a short cementless humeral component in anatomical (TSA) and reverse shoulder arthroplasty (RSA). Patients and Methods A total of 100 shoulder arthroplasties (35 TSA and 65 RSA) were evaluated at a mean of 3.8 years (3 to 8.3). The mean age at the time of surgery was 68 years (31 to 90). The mean body mass index was 32.7 kg/m2 (17.3 to 66.4). Results Greater tuberosity stress shielding was noted in 14 shoulders (two TSA and 12 RSA) and was graded as mild in nine, moderate in two, and severe in three. Medial calcar resorption was noted in 23 shoulders (seven TSA and 16 RSA), and was graded as mild in 21 and moderate in two. No humeral components were revised for loosening or considered to be loose radiologically. Nine shoulders underwent reoperation for infection (n = 3), fracture of the humeral tray (n = 2), aseptic glenoid loosening (n = 1), and instability (n = 3). No periprosthetic fractures occurred. Conclusion Implantation of this particular short cementless humeral component at the time of TSA or RSA was associated with a low rate of adverse radiological findings on the humeral side at mid-term follow-up. Our data do not raise any concerns regarding the use of a short stem in TSA or RSA. Cite this article: Bone Joint J 2019;101-B:610–614.

External rotation of the Achillon decreased the rate of sural nerve violation. This may optimize its use in Achilles tendon repairs.

These findings demonstrate the need for careful patient selection. In patients with the most complicated scaphoid nonunions (avascular necrosis, carpal collapse, and previous surgeries), the MFC group had the highest union rate and fastest time to union. Patients with risk factors for failure should be counseled on the outcomes and possible need for salvage fusion surgery.

Background: It is unknown whether subscapularis management technique has an influence on the outcomes and complications of stemless total shoulder arthroplasty. The purpose of this study, therefore, was to compare outcomes and complications between subscapularis tenotomy, peel, and lesser tuberosity osteotomy used during stemless shoulder arthroplasty. Methods: We reviewed 188 stemless anatomic total shoulder arthroplasties and compared clinical and functional outcomes between those performed through a subscapularis tenotomy (n ¼ 68), subscapularis peel (n ¼ 65), or lesser tuberosity osteotomy (n ¼ 55). Patients were followed up clinically and radiographically at 6 months, 1 year, and 2 years postoperatively. Results: At 2 years postoperatively, no statistically significant differences in visual analog scale pain scores, American Shoulder and Elbow Surgeons scores, or patient-reported instability (P .19) were found between groups. Active external rotation was greater in the peel group (P ¼ .006) than in the tenotomy group but was not different compared with the lesser tuberosity osteotomy group (P ¼ .07). No statistically significant difference in clinical subscapularis failures was noted between groups (P ¼ .11); however, 2 patients in the peel group sustained a subscapularis failure requiring reoperation. Discussion: The results of this multicenter comparative analysis show that all 3 subscapularis management techniques are effective and safe in the short term when used with stemless anatomic total shoulder arthroplasty.
