It is essential that the complex biological processes related to bone immunogenicity are understood, since this may allow the development of safer and more successful ways of controlling the outcome of bone allografting.

BACKGROUND: Different methods have been developed and employed with variable degrees of success in pre-operative templating for total hip arthroplasty. Preoperative templating, especially digital templating, has been claimed to have increased the effectiveness of total hip arthroplasty by improving the precision of prediction of prosthetic implant size. AIMS: The overall aim of this systematic review is to identify whether the use of pre-operative templating in total hip arthroplasty procedures has resulted in increased accuracy, reliability and precision of the procedure. Various methods of templating, like traditional acetate overlay and digital method of templating that includes a single radiographic marker and double radiographic marker methods, have been compared to establish the most reliable method of templating. METHODS: We searched the PubMed, Google Scholar Cochrane Central Register of Controlled Trials (CENTRAL), and MEDLINE (1966 to present), EMBASE (1980 to present), CINAHL (1982 to present), Psych INFO (1967 to present) and Clinical Trials Gov. CONCLUSION: The results of this systemic review suggest that preoperative templating is resulting in an enormous increase in the accuracy of total hip arthroplasty and among various methods, King Mark is the most reliable method.

BackgroundThe aim of our study was to determine the rate and preoperative predictors of intraoperative fracture (IOF) during hip hemiarthroplasty (HA) in patients who have sustained a fragility hip fracture injury.MethodsWe reviewed 626 patients who underwent HA at our institution using the National Hip Fracture Database. Various patient- and surgery-related data including demographic information, cement usage, surgeon grade, time to surgery, and operative duration were collected. The metaphyseal diaphyseal index and modified canal bone ratio were measured on preoperative radiographs. We compared patients with and without IOF with respect to all variables collected. Multivariate regression modeling was used to identify significant preoperative risk factors for IOF.ResultsThere was a 7% incidence of IOF in our cohort exclusively comprising of Vancouver A fractures. The majority of these complications were treated nonoperatively (52%). There was no statistically significant difference with respect to cement usage, surgeon grade, operative duration, time to surgery, and radiographic parameters collected. Increasing age was found to be the most significant preoperative risk factor for predicting IOF (p = 0.024, overall relative risk = 1.06).ConclusionsOur identified predictor of increasing age is nonmodifiable and illustrates the importance of meticulous surgical technique in older patients. Furthermore, its independence from fixation methods or prosthesis design as a predictor of IOF may support using an uncemented prosthesis in patients at risk from cement implantation.

ObjectiveThis article assesses the efficacy of modern technology in improving education using neurovascular examination (NVE). To determine whether revision of NVE is facilitated with online video services. MethodsThis prospective study assessed medical students (n=260) and junior doctors (n=238) upper and lower limb NVE knowledge with an exam. A course utilising online videos was delivered. NVE knowledge was tested after the course. After one month, participants (n=100) were invited to watch the videos online and re sit the test. ResultsMean score of participants before the course was 2.76/8 for UL and 2.67/10 for LL. After delivery of the course there was a significant improvement in scores to 7.83/8 for UL and 9.33/10 for LL (p=<0.005). Statistical analysis revealed no significant difference in scores from just after the course to one month after (p=0.765 UL, p=0.779 LL). ConclusionsIntegrating online video tutorials with traditional teaching methods demonstrated a significant rise in performance. Revision is facilitated due to its availability and ease of use. This helps with performing an adequate and complete NVE. We recommend academic institutions adapt such educational technologies to advance learning improve patient care. Educational theories should be utilised to optimise their delivery.

Aim It is not uncommon to find rota gaps at junior doctors’ level across many NHS Trusts within United Kingdom – especially in district general hospitals. In the trauma and orthopaedic department at Huddersfield Royal Infirmary, there were significant rota gaps that frequently relied on locum doctors to provide adequate service coverage. The aim of the audit was to determine whether rota gaps had any impact on safe staffing levels, training of core surgical trainees (CSTs) and costs to the department. Method Retrospective audit - assess daily staffing levels as per rota for three weeks before and after implementation of recommended better utilisation of the department’s Advanced Clinical Practitioners (ACPs) to cover trauma wards. The audit took place over October 2018 – December 2018. Results There were safe staffing levels daily in both audits. Audit 1 demonstrated locum doctors were required to cover 36.6% of ward duties and 42.9% of oncall shifts – costing the department £25, 190. Following implementation of recommendation, where ACPs were rostered to cover trauma, audit 2 reduced the requirements of locum doctors for coverage of ward duties and oncalls to 23.7% and 33.3%, respectively. Protected theatre allocation of CSTs remained less than 1 day/week. The cost of locum doctors in audit 2 was reduced to £17, 050. Conclusions Through better utilisation of the department’s ACPs to cover trauma wards, we managed to significantly reduce cost of locum doctors by £8, 140 over a three-week period. We believe CST theatre allocation will also improve from this intervention.
