Aims. Global literature suggests that female surgical trainees have lower rates of independent operating (operative autonomy) than their male counterparts. The objective of this study was to identify any association between gender and lead/independent operating in speciality orthopaedic trainees within the UK national training programme. Methods. This was a retrospective case-control study using electronic surgical logbook data from 2009 to 2021 for 274 UK orthopaedic trainees. Total operative numbers and level of supervision were compared between male and female trainees, with correction for less than full-time training (LTFT), prior experience, and time out during training (OOP). The primary outcome was the percentage of cases undertaken as
Mortality following hip arthroplasty is affected by a large number of confounding variables each of which must be considered to enable valid interpretation. The aim of this study was to establish whether it is possible to determine a true cause-and-effect relationship between the risk of mortality and data that are routinely collected by the NJR and to establish the degree to which variation in the mortality rate could be explained by each variable. Relevant variables available from the 2011 NJR data setwere included in a Cox model. We carried out two analyses:. Firstly, we conducted an analysis of data collected from the NJR data set used in preparation of the NJR's 8th Annual Report (2011) looking for an association between the variables collected and the risk of mortality. Secondly, as social deprivation is also known to influence mortalityrates but is not routinely collected as part of the NJR data set, a further analysis was performed which included social deprivation data derived from partial postcodes. Mortality rates in hip arthroplasty patients were lower than in the age matched population across all hip types. Age at surgery, ASA grade, diagnosis, gender, provider type, hip type and
The purpose of this study was to examine the utility of the acetabular component introducer as a tool to intra-operatively predict implant inclination in total hip arthroplasty. This study investigated (1) the correlation between intra-operative photographic assessment of cup inclination using the acetabular introducer and that measured on post-operative radiograph; and (2) the accuracy of intra-operative prediction of abduction angle. For this study, we prospectively recruited 56 patients scheduled to receive primary hip arthroplasty from one of two senior surgeons. During the procedure, the
Introduction. Accurate prosthetic cup placement is very important in total hip arthroplasty (THA). When the surgeon is impacting the acetabular cup, it is assumed that the patient's pelvis is perpendicular to the operating table. In reality the pelvis may not be truly lateral, and error in patient positioning may influence the resultant cup orientation. Objectives. The primary aim of this study was to examine the accuracy of patient positioning prior to THA. A secondary aim was to see if patient BMI influenced the accuracy of positioning. Method. A consecutive series of 36 patients undergoing total hip arthroplasty were investigated. Once the
