International trends in shoulder replacement: a meta-analysis from 11 public joint registers.

BACKGROUND AND PURPOSE: International variation exists in the types of shoulder replacement used for treatment of specific diseases. Implant choice continues to evolve without high-quality evidence. Our aim was to evaluate trends in incidence rates of shoulder replacement and assess any recent changes in practice between countries by using registry data. METHODS: Patient characteristics, indication and year of surgery, type of replacement, and collection methods of patient-reported outcomes (PROMs) was extracted from 11 public joint registries. Meta-analyses examined use of reverse total shoulder replacement (RTSR) for osteoarthritis, cuff tear arthropathy, and acute fracture; use of anatomical total shoulder replacement (TSR) for osteoarthritis; and use of humeral hemiarthroplasty for fracture. RESULTS: The annual growth rate of shoulder replacements performed is 6-15% (2011-2019). The use of RTSR has almost doubled (93%). RTSR is now universally performed for cuff tear arthropathy (97.3%, 95% confidence interval [CI] 96.0-98.1). Its use for avascular necrosis, trauma, and inflammatory arthropathy is increasing. The use of RTSR was similar (43.1%, CI 30.0-57.2) versus TSR (44.7%, CI 31.1-59.1) for osteoarthritis. The types of PROMs used, collection time points, and response rates lack standardization. COVID-19 had a varying inter-registry impact on incidence rates. CONCLUSION: The incidence of shoulder replacements has grown. Use of RTSR has increased for all disease indications despite limited high-quality evidence driving this change in indications outside of cuff arthropathy. Consequently, less variation is observed in international practice. Existing differences now relate to use of newer implant types and methodology of PROMs collection, which prevents international comparison and outcome analysis.

A quantitative cross-sectional study assessing the surgical trainee perception of the operating room educational environment.

BACKGROUND: Limited hours and service provision are diminishing training opportunities, whilst increasing standards of surgical proficiency is being sought. It is imperative to maximise the value of each educational event. An objective measure of higher surgical trainee perception of the operating room environment in England has not been performed before and this can steer future change in optimising educational events in theatre. The Operating Room Educational Environment Measure (OREEM) evaluates each component of the learning environment to enable optimisation of these educational events. However, the OREEM has not yet been assessed for reliability in higher surgical trainees in England. The aim of the current study was to explore areas of strength and weakness in the educational environment in the operating room as perceived by surgical trainees' in one English region. The secondary aim was to assess the reliability of the OREEM. METHODS: Using a quantitative approach, data was collected over one month from surgical trainees in England using the OREEM. RESULTS: Fifty-four surgical trainees completed the questionnaire. The OREEM had good internal consistency (α = 0.906, variables = 40). The mean OREEM score was 79.16%. Areas for improvement included better learning opportunities (average subscale score = 72.9%) and conducting pre- and post-operative teaching (average score = 70.4%). Trainees were most satisfied with the level of supervision and workload (average subscale score = 82.87%). The learning environment favoured senior trainees (p = 0.017). There was a strong correlation between OREEM and the global satisfaction score (p < 0.001). CONCLUSIONS: The OREEM was shown to be a reliable measure of the educational environment. It can be used to identify areas of improvement and as an audit tool. The current perception of the education environment is satisfactory, however, areas of improvement include reducing service provision, empowering trainees to plan lists, improving teamwork and using tools to optimise the educational value of each operation. There is a favourable attitude regarding the use of improvement tools, especially for dissatisfied trainees.

Spontaneous Healing of a Pediatric Scaphoid Proximal Pole Fracture Nonunion.

Background Scaphoid fractures in the pediatric population are rare. The majority of nondisplaced fractures tend to unite; however, there is an increased risk of nonunion in proximal pole fractures. Limited evidence exists in their outcomes, owing to the scarcity of the fracture pattern. Case Description A 13-year-old boy who presented late after developing a traumatic proximal pole scaphoid fracture developed nonunion. He was treated conservatively owing to it being asymptomatic and developed union at 18 months. Literature Review No previous case of proximal pole pediatric scaphoid fractures with established nonunion that has developed union with conservative management has been described. Clinical Relevance The authors highlight a unique case of an established proximal pole scaphoid nonunion in a child progressing to union with nonoperative intervention. Owing to its rarity and difficulty in obtaining research, we recommend consideration of nonoperative management of asymptomatic nondisplaced proximal pole fractures in children.

Managing acromio-clavicular joint pain: a scoping review.

BACKGROUND: Shoulder pain secondary to acromioclavicular joint pain is a common presentation in primary and secondary care but is often poorly managed as a result of uncertainty about optimal treatment strategies. Osteoarthritis is the commonest cause. Although acromioclavicular pain can be treated non-operatively and operatively, there appears to be no consensus on the best practice pathway of care for these patients, with variations in treatment being common place. The present study comprises a scoping review of the current published evidence for the management of isolated acromioclavicular pain (excluding acromioclavicular joint dislocation). METHODS: A comprehensive search strategy was utilized in multiple medical databases to identify level 1 and 2 randomised controlled trials, nonrandomised controlled trials and systematic reviews for appraisal. RESULTS: Four systematic reviews and two randomised controlled trials were identified. No direct studies have compared the benefits or risks of conservative versus surgical management in a controlled environment. CONCLUSIONS: High-level studies on treatment modalities for acromioclavicular joint pain are limited. As such, there remains little evidence to support one intervention or treatment over another, making it difficult to develop any evidenced-based patient pathways of care for this condition.Level of evidence: 2A.
