Introduction

Training the next generation of surgeon's forms part of routine Consultant practice. Stress causes activation of the Autonomic Nervous System and this can be directly measured using heart rate (HR). Training time is limited with pressures from EWTD and management and efficiency targets. The aim of this study was to assess whether being an orthopaedic trainer is more stressful than performing the surgery.

Methodology

This was a prospective multicentre study. Consultant orthopaedic surgeon HR was monitored intra-operatively using a ‘Wahoo Fitness’ chest strap and the data recorded by the proprietary Android app. Data was collected prior to surgery to obtain a resting heart rate, and at set points during total hip arthroplasty (THA) and total knee arthroplasty (TKA).

The peak and mean HR for each stage of the operation were recorded and compared to cases where the consultant surgeon was performing the case or assisting a trainee. Data was compared with a 2-way ANOVA with repeated measures.

Despite a lack of long-term follow-up, there is an increasing trend towards using femoral heads of large diameter in total hip replacement (THR), partly because of the perceived advantage of lower rates of dislocation. However, increasing the size of the femoral head is not the only way to reduce the rate of dislocation; optimal alignment of the components and repair of the posterior capsule could achieve a similar effect.

In this prospective study of 512 cemented unilateral THRs (Male:Female 230:282) performed between 2004 and 2011, we aimed to determine the rate of dislocation in patients who received a 22 mm head on a 9/10 Morse taper through a posterior approach with capsular repair and using the transverse acetabular ligament (TAL) as a guide for the alignment of the acetabular component. The mean age of the patients at operation was 67 years (35 to 89). The mean follow-up was 2.8 years (0.5 to 6.6). Pre- and post-operative assessment included Oxford hip, Short Form-12 and modified University of California Los Angeles and Merle D’Aubigne scores. The angles of inclination and anteversion of the acetabular components were measured using radiological software. There were four dislocations (0.78%), all of which were anterior.

In conclusion, THR with a 22 mm diameter head performed through a posterior approach with capsular repair and using the TAL as a guide for the alignment of the acetabular component was associated with a low rate of dislocation.
