Aims. The COVID-19 pandemic has disrupted the provision of arthroplasty services in England, Wales, and Northern Ireland. This study aimed to quantify the backlog, analyze national trends, and predict time to recovery. Methods. We performed an analysis of the mandatory prospective national registry of all independent and publicly funded hip, knee,

The aim of this study was to longitudinally compare the clinical and radiological outcomes of anatomical total shoulder arthroplasty (aTSA) up to long-term follow-up, when using cemented keel, cemented peg, and hybrid cage peg glenoid components and the same humeral system.

Aims. The aim of this study was to compare the clinical and radiological outcomes of reverse shoulder arthroplasty (RSA) using small and standard baseplates in Asian patients, and to investigate the impact of a mismatch in the sizes of the glenoid and the baseplate on the outcomes. Methods. This was retrospective analysis of 50 and 33 RSAs using a standard (33.8 mm, ST group) and a small (29.5 mm, SM group) baseplate of the Equinoxe reverse
Aims. Corticosteroid injections are often used to manage glenohumeral arthritis in patients who may be candidates for future total shoulder arthroplasty (TSA) or reverse shoulder arthroplasty (rTSA). In the conservative management of these patients, corticosteroid injections are often provided for symptomatic relief. The purpose of this study was to determine if the timing of corticosteroid injections prior to TSA or rTSA is associated with changes in rates of revision and periprosthetic joint infection (PJI) following these procedures. Methods. Data were collected from a national insurance database from January 2006 to December 2017. Patients who underwent

Aims. Open reduction and plate fixation (ORPF) for displaced proximal humerus fractures can achieve reliably good long-term outcomes. However, a minority of patients have persistent pain and stiffness after surgery and may benefit from open arthrolysis, subacromial decompression, and removal of metalwork (ADROM). The long-term results of ADROM remain unknown; we aimed to assess outcomes of patients undergoing this procedure for stiffness following ORPF, and assess predictors of poor outcome. Methods. Between 1998 and 2018, 424 consecutive patients were treated with primary ORPF for proximal humerus fracture. ADROM was offered to symptomatic patients with a healed fracture at six months postoperatively. Patients were followed up retrospectively with demographic data, fracture characteristics, and complications recorded. Active range of motion (aROM), Oxford
The natural history of primary anterior dislocation
of the glenohumeral joint in adolescent patients remains unclear and
there is no consensus for management of these patients. The objectives of this study were to report the natural history
of primary anterior dislocation of the glenohumeral joint in adolescent
patients and to identify the risk factors for recurrent dislocation. We reviewed prospectively-collected clinical and radiological
data on 133 adolescent patients diagnosed with a primary anterior
dislocation of the glenohumeral joint who had been managed non-operatively
at our hospital between 1996 and 2008. There were 115 male (86.5%)
and 18 female patients (13.5%) with a mean age of 16.3 years (13
to 18) and a mean follow-up of 95.2 months (1 to 215). During follow-up, 102 (absolute incidence of 76.7%) patients
had a recurrent dislocation. The median interval between primary

Mean time to revision surgery of Copeland implants was 37 months
(standard deviation (. sd. ) 23; 14 to 72) and Epoca RH 38
months (. sd. 28; 12 to 84). The mean age of patients investigated
was 66 years (. sd. 4; 59 to 71) and 58 years (. sd. 17;
31 to 73) in the Copeland and Epoca RH groups respectively. None
of these implants were revised for loosening. . Results. Increased osteointegration was measured under the cup in the
Copeland implant group with limited bone seen in direct contact
with the central stem. Bone adjacent to the Epoca RH implants was
more uniform. . Conclusion. This difference in the distribution of bone-implant contact and
bone formation was attributed to the Epoca implant’s conical crown,
which is positioned in more dense peripheral bone. The use of a
central stem may not be necessary provided there is adequate peripheral
fixation within good quality humeral bone. Take home message: Poor osteointegration of cementless surface

We carried out a prospective, randomised controlled trial on two groups of 40 patients with painful calcific tendonitis and a mean age of 48.4 years (32.5 to 67.3). All were to undergo arthroscopic removal of the calcific deposit within six months after randomisation. The 40 patients in group I received ultrasound-guided needling followed by high-energy shock-wave therapy and the 40 in group II had shock-wave therapy alone. In both groups one treatment consisting of 2500 impulses of shock waves with an energy flux density of 0.36 mJ/mm. 2. was applied.
