Elbow arthrodesis is a salvage operation designed to relieve pain and enable weight bearing in young patients with painful arthritic joints who have failed all other treatment modalities. Unfortunately, elbow arthrodesis is poorly tolerated by many patients because there is no fusion position that accommodates all activities of daily living. As indications for elbow arthroplasty expand and implant design improves, patients living with elbow arthrodesis may seek conversion to arthroplasty to regain a functional range of motion. Only one case of elbow arthrodesis to elbow arthroplasty conversion has been reported in the English literature to date. We present the case of a 58 year old male, five years status post elbow arthrodesis, unable to perform his ADLs adequately, who was successfully converted to a total elbow arthroplasty. Indications, contraindications, and technical pearls are discussed.

Introduction: Complex fractures of the proximal humerus with splitting-head component and metaphyseal propagation are very rare injuries that are difficult to treat. Preservation of the humeral head is always considered except in cases with severe comminution and compromised vascularity where shoulder hemiarthroplasty is an alternative option.

Case report: We present two male patients, 57- and 62-years-old who sustained such a complex proximal humeral fracture after a high-energy injury. They both managed with long-stemmed shoulder hemiarthroplasty and cerclage wiring of the metaphyseal area. They both demonstrated good clinical and radiological outcome at 32- and 24-months postoperatively.

Conclusion: We report the functional and radiological outcomes of two cases of a rare proximal humeral fracture's pattern - combination of splitting-head and metaphyseal comminution - that were managed with long-stemmed hemiarthroplasty and cerclage wire and demonstrated good midterm clinical outcome.

Background: Reverse shoulder arthroplasty (RSA) is commonly used in the treatment of rotator cuff arthropathy. Indications for RSA have expanded to include complex proximal humerus fractures. Studies directly comparing outcomes between traumatic and traditional elective indications are limited. The purpose of this study was to compare early active range of motion (aROM) within the first two years postoperatively between traumatic and non-traumatic primary RSA, as well as compare ASES scores, and patient satisfaction at final follow-up.

Methods: A retrospective analysis was conducted of all RSA performed by a single surgeon between January 2000 and December 2018. Patients were grouped by indication into traumatic and non-traumatic elective groups. Demographics, surgical data, and routine aROM data were collected. aROM was compared at 3, 6, 12, and 24 months. American Shoulder and Elbow Surgeons (ASES) score and patient satisfaction were determined at the time of this investigation.

Results: 367 RSA procedures were performed by the senior author during the study period, 88 for fracture (24%), and 279 for non-traumatic elective indications (76%). Forward elevation and external rotation were inferior in the fracture group at all time points in the first two years. Internal rotation was equivalent throughout the first two years. Final ASES scores were 77.6 versus 83.5 in the fracture and non-fracture groups, respectively (p = .33).

Conclusion: Patients undergoing RSA for fracture had statistically significant inferior aROM in forward elevation and external rotation throughout the first two years. Despite having inferior aROM, ASES scores and patient satisfaction at final follow-up were statistically equivalent.

Level of evidence: Level III; Retrospective Cohort Comparision; Prognosis Study.

Background: The COVID-19 Pandemic has affected the way health care systems function across the globe. Apart from eliminating the risk of being in a vulnerable environment during the pandemic such as a hospital setting, virtual arthroplasty follow-up reduces the demand on funding and resources on the National Health Services (NHS).

Methods: We retrospectively reviewed our shoulder arthroplasty patients (55) operated between October 2018 to November 2020 at both our hospital sites. For remote follow-up, patients were contacted on a scheduled appointment date via telephone by an orthopaedic surgeon to enquire about their wound, pain and function. Patients were questioned as per questionnaire from the Oxford Shoulder Score (OSS) and American Shoulder and Elbow Surgeons (ASES) Standardised Assessment form.

Results: 50 patients were included in the final data set after excluding those who had died (5 patients). All patients had had final x-rays with full Covid-19 precautions at the time of final follow-up. No patient had wound problems except one who had concerns of wound appearance. There were no cases of notching, impingement, deep infection, dislocation or nerve injury. Of the 50 patients, 40 (80%) patients were satisfied to have a remote follow-up. 36 (72%) patients said they wouldn't mind a remote follow-up appointment.

Conclusion: Remote follow-up via audio consultation may be an effective alternative to in person visits after shoulder arthroplasty. Patients in this series demonstrated a high level of satisfaction with virtual visits and post-operative complications were effectively identified.

The indication for total elbow arthroplasty (TEA) for primary and posttraumatic elbow arthritis has increased, however, its indication after infection remains elusive. Wound closure about the elbow increases the challenge of treating a previously infected elbow, often necessitating soft tissue coverage with local or regional flaps. We present a 75-year-old male patient with an elbow infection following a failed complex intraarticular fracture open reduction and internal fixation of the distal humerus. Initially, he presented with severe functional impairment and pain, also with an active fistula with serous exudate, whose culture was positive for Cutinebacterium acnes. Septic hardware loosening, and septic nonunion with intraarticular involvement of the left elbow was diagnosed. The patient underwent hardware removal, fistulectomy, serial irrigation and debridement and a pedicled antegrade posterior interosseous artery (PIA) flap on staged surgical treatment. Finally, after ruling out infection persistence, a TEA was performed. We aim to report the outcome of a patient treated with a TEA in the context of a previously infected elbow with soft tissue coverage with an antegrade PIA flap. Comprehensive treatment must be done in an appropriate manner, to obtain an expedited and desirable outcome.

Total shoulder arthroplasty is an increasingly popular option for the treatment of glenohumeral arthritis. Historically, the effectiveness of the procedure has largely been determined by the long-term stability of the glenoid component. Glenoid component loosening can lead to clinically concerning complications including pain with movement, loss of function, and accumulation of debris which may require surgery to revise. In response, there has been a push to optimize the design of the glenoid prosthesis. Traditional contemporary glenoid components use pegs for fixation and are made entirely of polyethylene. Variations on the standard implant include keeled, metal-backed, hybrid, augmented, and inlay designs. There is a wealth of biomechanical and clinical studies that report on the effectiveness of these different designs. The purpose of this review is to summarize existing literature regarding glenoid component design and identify key areas for future research. Knowledge of the rationale underlying glenoid design will help surgeons select the best component for their patients and optimize outcomes following TSA.
