Aims. The
The Oxford Shoulder Score (OSS) is a 12-item measure commonly used for the assessment of shoulder surgeries. This study explores whether computerized adaptive testing (CAT) provides a shortened, individually tailored questionnaire while maintaining test accuracy. A total of 16,238 preoperative OSS were available in the National Joint Registry (NJR) for England, Wales, Northern Ireland, the Isle of Man, and the States of Guernsey dataset (April 2012 to April 2022). Prior to CAT, the foundational item response theory (IRT) assumptions of unidimensionality, monotonicity, and local independence were established. CAT compared sequential item selection with stopping criteria set at standard error (SE) < 0.32 and SE < 0.45 (equivalent to reliability coefficients of 0.90 and 0.80) to full-length patient-reported outcome measure (PROM) precision.Aims
Methods
A pragmatic multicentre randomized controlled trial, UK FROzen Shoulder Trial (UK FROST), was conducted in the UK NHS comparing the cost-effectiveness of commonly used treatments for adults with primary frozen shoulder in secondary care. A cost utility analysis from the NHS perspective was performed. Differences between manipulation under anaesthesia (MUA), arthroscopic capsular release (ACR), and early structured physiotherapy plus steroid injection (ESP) in costs (2018 GBP price base) and quality adjusted life years (QALYs) at one year were used to estimate the cost-effectiveness of the treatments using regression methods.Aims
Methods
The goal of this study is to investigate the relation between indicators of osteoporosis (i.e., bone mineral density (BMD), and Cortical Index (CI)) and the complexity of a fracture of the proximal humerus as a result of a low-energy trauma. A retrospective chart review of 168 patients (mean age 67.2 years, range 51 to 88.7) with a fracture of the proximal humerus between 2007 and 2011, whose BMD was assessed at the Fracture Liaison Service with Dual Energy X-ray Absorptiometry (DXA) measurements of the hip, femoral neck (FN) and/or lumbar spine (LS), and whose CI and complexity of fracture were assessed on plain anteroposterior radiographs of the proximal humerus.Objectives
Methods
This pilot study reports the clinical outcomes
of a combination of partial subscapularis tendon transfer and small-head
hemiarthroplasty in patients with rotatator cuff arthropathy. A
total of 30 patients (30 shoulders; eight men and 22 women) with
a mean age of 74 years (55 to 84) were assessed at a mean follow-up
of 31 months (24 to 60). The inclusion criteria were painful cuff
tear arthropathy with normal deltoid function and a non-degenerative subscapularis
muscle and tendon and a preserved teres minor. Outcome was assessed using the University of California Los Angeles
score, the Japanese Orthopaedic Association score, and the Oxford
Shoulder Score. Radiographic measurements included the centre of
rotation distance and the length of the deltoid. All clinical scores were significantly improved post-operatively.
The active flexion and external rotation improved significantly
at the most recent follow-up (p <
0.035). Although the mean centre
of rotation distance changed significantly (p <
0.001), the mean
length of the deltoid did not change significantly from the pre-operative
value (p = 0.29). The change in the length of the deltoid with <
100° flexion was significantly less than that with >
100° (p <
0.001). Progressive erosion of the glenoid was seen in four patients.
No patient required revision or further surgery. A combination of partial subscapularis tendon transfer and small-head
hemiarthroplasty effectively restored function and relieved pain
in patients with rotator cuff arthropathy. Cite this article: 2015;97-B:1090–5.
