Purpose: We report here on a solution for the case of a 71 year old lady with cartilage destruction in the left shoulder and the loss of the rotator cuff secondary to post-septic arthritic sequelae. Materials and methods: After thorough laboratory, clinical and radiological investigation of the patient to rule out any foci of active infection, we contemplated performing reverse total shoulder arthroplasty as a primary procedure. Results: At 22 months follow up, the patient had an excellent result according to the UCLA and ASES scales. Conclusion: Reverse total shoulder arthroplasty seems to be an efficient procedure to improve pain and function in the post-septic shoulder accompanying severe rotator cuff injury.

Reverse total shoulder arthroplasty (RTSA) is a surgical method that has recently been conducted in widely irrepairable rotator cuff tears with pseudoparalysis, cuff tear arthropathy, and osteoarthritis of the shoulder joint. Several topics can be described, but this review article provides an opinion on the criteria for the choice of implant in RTSA.

Historically, the decision to perform a hemiarthroplasty (HHR) versus a total shoulder arthroplasty (TSA) is based on the status of the glenoid and the status of the soft tissues (rotator cuff). In disease processes where the glenoid articular cartilage is relatively well preserved such as avascular necrosis and complex proximal humerus fractures, most orthopaedists recommend performing a HHR while preserving the native glenoid articular surface. At the other end of the spectrum, if the glenoid has excessive bone loss or is unreconstructible, a HHR is the preferred procedure. In patients who have deficient so(t-tissues (rotator cuff) such as rotator cuff tear arthropathy and, occasionally, rheumatoid arthritis, a HHR is the procedure of choice. The indications for HHR in osteoarthritis remain somewhat controversial. There is mounting evidence that performing a HHR for osteoarthritis is inferior to TSA. Recent developments, or 'third generation techniques and materials', in shoulder arthroplasty are expected to improve the longevity of TSA, particularly the glenoid component. In addition, newer designs of reverse-ball prostheses are entering the market with promising early results in patients with deficient rotator cuff mechanisms.

Total elbow arthroplasty is a relatively rare procedure compared with total knee or total hip arthroplasty. Total elbow arthroplasty for bony ankylosis is even rarer, and the results are often unsatisfactory. We report a patient who gained good mobility of the elbow after total elbow arthroplasty for the treatment of fractured arthrodesis site with which the patient had lived with for 12 years.

Background: Advancements in airport screening measures in response to 9/11 have resulted in increased false alarm rates for patients with orthopedic and metal implants. With the implementation of millimeter-wave scanning technology, it is important to assess the changes in airport screening experiences of patients who underwent total shoulder arthroplasty (TSA). Methods: Here, 197 patients with prior anatomic and reverse TSA completed between 2013 and 2020 responded to a questionnaire regarding their experiences with airport travel screening after their operation. Of these patients, 86 (44%) stated that they had traveled by plane, while 111 (56%) had not. The questionnaire addressed several measures including the number of domestic and international flights following the operation, number of false alarm screenings by the millimeter-wave scanner, patient body habitus, and presence of additional metal implants. Results: A total of 53 patients (62%) responded "yes" to false screening alarms due to shoulder arthroplasty. The odds of a false screening alarm for patients with other metal implants was 5.87 times that of a false screening alarm for patients with no other metal implants (P<0.1). Of a reported 662 flights, 303 (45.8%) resulted in false screening alarms. Greater body mass index was not significantly lower in patients who experienced false screening alarms (P=0.30). Conclusions: Patients with anatomic and reverse TSA trigger false alarms with millimeter-wave scanners during airport screening at rates consistent with prior reports following 9/11. Patient education on the possibility of false alarms during airport screening is important until improvements in implant identification are made. Level of evidence: IV.

Background: The purpose of this study is to evaluate the functional outcomes of reverse total shoulder arthroplasty (RTSA) and to assess factors affecting the patients' subjective satisfaction after RTSA. Methods: Forty-three patients (mean age, $75.0{\pm}5.2years$) who underwent RTSA for cuff tear arthropathy or irreparable cuff tears with preoperative magnetic resonance imaging and pre- and postoperative radiographs at 1 year, and whose various functional outcomes including pain visual analogue scale (VAS), simple shoulder test, Constant score, American Shoulder and Elbow Surgeons score, and active range of motion were evaluated preoperatively and at the last follow-up (>12 months) were enrolled. The outcome parameter was set as a satisfaction scale. Various clinical and radiographic factors were analyzed, and their correlations with postoperative satisfaction were evaluated. Results: All functional scores, VAS pain score, and active forward flexion showed significant improvement after surgery (all p<0.001). Twenty-nine patients were satisfied with the results and 14 were dissatisfied. The presence of pseudoparalysis (p=0.028) and worse preoperative function (all p<0.05) were related with higher satisfaction. Any radiologic parameters did not affect patients' postoperative satisfaction. Conclusions: All patients showed a good functional outcome after RTSA, however the patients' subjective postoperative satisfaction was affected by preoperative functional status (higher satisfaction in poor preoperative function), not by radiological findings.

Humeral head chondrolysis has been widely reported as a devastating complication after arthroscopic shoulder surgery; however little is known about post-arthroscopic humeral head osteonecrosis. We experienced a 66-year-old female patient with rapidly progressive osteonecrosis of the humeral head only seven months after arthroscopic Bankart and rotator cuff repair. The patient had no systemic risk factors for osteonecrosis. A satisfactory result was achieved with reverse total shoulder arthroplasty for severe humeral head destruction and an irreparable massive rotator cuff tear. Shoulder surgeons should be aware of such severe complication, perform routine radiographs, and pay close attention to the presence of constant pain or loss of motion after arthroscopic shoulder surgery.
