Pre-operative planning for reverse shoulder arthroplasty in low-resource centres: A modified Delphi study in South Africa.

Background: Pre-operative planning for reverse shoulder arthroplasty (RSA) poses challenges, particularly when dealing with glenoid bone loss. This modified Delphi study aimed to assess expert consensus on RSA planning processes and rationale, specifically targeting low-resourced institutions. Our objective was to offer pre-operative decision-making algorithms tailored for surgeons practising in resource-constrained hospitals with limited access to computed tomography (CT) scans.

Moment arms of the coracobrachialis and short head of biceps following a Latarjet procedure: a modeling study.

Background: The Latarjet procedure transfers the coracoid process to the anterior glenoid. This prevents recurrent anterior humeral dislocation but alters the origins of the coracobrachialis (CBR) and short head of the biceps (SHB). The impact of this alteration on the moment arms of these muscles has not been examined.

A narrative review of treatment strategies for major glenoid defects during primary reverse shoulder arthroplasty, with a focus on the use of structural bone graft.

Structural glenoid defects are common during primary reverse shoulder arthroplasty (RSA) and are often associated with poor outcomes. The lack of pre-operative imaging protocols for determining the depth and degree of glenoid wear hinders our ability to accurately plan and correct these defects. Although bone grafting has been reported to be effective in reducing glenoid wear during RSA, there is limited information on when to utilise it and how to prepare the graft.

Surgical management of distal humerus gunshot fractures: descriptive case series.

Purpose: The purpose of this study was to report our 5 years surgical experience and the rate of neurovascular injury following gunshot fractures of the distal humerus in a in level-1 Trauma Centre in South Africa.

Methods: A retrospective case series of 25 consecutive adult gunshot injuries to the distal humerus. Demographic and injury data were extracted from clinical case notes and electronic operative records.

Characterizing moment arms of the coracobrachialis and short head of biceps in native shoulders and after reverse total shoulder arthroplasty during elevation and rotation: a modeling study.

Background: Reverse total shoulder arthroplasty (RTSA) alters the line of action of muscles around the glenohumeral joint. The effects of these changes have been well characterized for the deltoid, but there is limited information regarding the biomechanical changes to the coracobrachialis (CBR) and short head of biceps (SHB). In this biomechanical study, we investigated the changes to the moment arms of the CBR and SHB due to RTSA using a computational model of the shoulder.

Assessment and management of shoulder pain at primary care level.

Most patients with shoulder pain will initially visit their community health centre, private general practitioner or family physician, with various levels of experience in the assessment and management of shoulder conditions. Shoulder conditions will range from early, simple ailments that can be treated in the primary care setting, to post-traumatic injuries and complex pathologies requiring the expertise of an orthopaedic surgeon or a fellowship-trained shoulder surgeon. Correct assessment of the patient's shoulder condition at the index consultation is a prerequisite for appropriate management.

A gender-based comparison of coracoid and glenoid anatomy: CT analysis and discussion of potential impact on the Latarjet procedure.

Background: The success of the modified Latarjet procedure depends on proper sizing of the coracoid graft. There is no information available regarding the morphometric relationship between the glenoid cavity and the coracoid process for the South African population. This study aims at measuring the relationship between the glenoid and coracoid morphometries and investigates their gender-related differences.

The modified Latarjet procedure in female patients: clinical outcomes and complications.

Background: The aim of this study was to assess the short- and medium-term complications and clinical outcomes of female patients after a modified Latarjet procedure. A review of the literature was also conducted for outcomes of the modified Latarjet procedure in female patients and differences reported between male and female patients.

Method: We retrospectively reviewed the clinical notes of all female patients who had modified Latarjet procedures from 2001 with at least 1 year of follow-up.

Outcomes After Ulnar Nerve In Situ Release During Total Elbow Arthroplasty.

Purpose: Ulnar nerve (UN) lesions are a significant complication after total elbow arthroplasty (TEA), with potentially debilitating consequences. Outcomes from a center, which routinely performs an in situ release of the nerve without transposition, were investigated.

Methods: Eighty-three primary TEAs were retrospectively reviewed for the intraoperative management of the UN and presence of postoperative UN symptoms.

Total elbow arthroplasty: outcomes after triceps-detaching and triceps-sparing approaches.

Background: Total elbow arthroplasty (TEA) is associated with high complication rates compared with other large-joint arthroplasties. The frequency and type of complication may differ, depending on the surgical approach. A comparison of outcomes with triceps-off and triceps-on approaches was investigated.

Angular stable fixation of displaced distal-third clavicle fractures with superior precontoured locking plates.

Hypothesis: We reviewed the outcome of angular stable plates in addressing displaced lateral-third clavicle fractures. We investigated union, shoulder function, request for implant removal, and return to sport. Our hypothesis was that these implants provide predictable union and return to sports without the negative consequence of leaving plates in situ, reducing the requirement for a second surgery.

Pediatric atlanto-occipital dissociation: radiographic findings and clinical outcome.

Study Design:  Retrospective diagnostic feasibility study and clinical review.

Objectives:  To evaluate the feasibility of making an initial atlanto-occipital dissociation (AOD) diagnosis from four radiological measurements of the craniocervical relationship on lateral cervical spine x-rays and to assess the AOD patients' clinical outcomes relative to their magnetic resonance imaging (MRI) findings.

Methods:  The Powers ratio, Wackenheim line, basion-dens distance (BDD), and the C1/2:C2/3 interspinous ratio were measured in 58 pediatric controls and ten MRI-confirmed patients with AOD.
