Total hip replacements (THRs) are performed by surgeons at various stages in their training, with varying levels of senior supervision. There is a balance between protecting training opportunities for the next generation of surgeons, while limiting the exposure of patients to unnecessary risk during the training process. The aim of this study was to examine the association between surgeon grade, the senior supervision of trainees, and the risk of revision following THR.

We included 603 474 primary THRs recorded in the National Joint Registry for England, Wales, Northern Ireland, and the Isle of Man (NJR) between 2003 and 2016 for an indication of osteoarthritis. Exposures were the grade of the surgeon (consultant or trainee), and whether trainees were supervised by a scrubbed consultant or not. Outcomes were all-cause revision, the indication for revision, and the temporal variation in risk of revision (all up to 10 years). Net failure was calculated using Kaplan-Meier analysis and adjusted analyses used Cox regression and flexible parametric survival analysis (adjusted for patient, operative, and unit level factors).

There was no association between surgeon grade and all-cause revision up to 10 years (crude hazard ratio (HR) 0·999, 95% confidence interval (CI) 0.936–1.065; p=0.966); a finding which persisted with adjusted analysis. Adjusted analysis demonstrated an association between trainees operating without supervision by a scrubbed consultant and an increase in all-cause revision (HR 1.100, 95% CI 1.002–1.207; p=0.045). There was an association between the trainee-performed THRs and revision due to instability (crude HR 1.143, 95% CI, 1.007–1.298; p=0.039). However, this was not observed in fully adjusted models, or when trainees were supervised by a scrubbed consultant.

Within the current training system in the United Kingdom, trainees achieve comparable outcomes to consultant surgeons when supervised by a scrubbed consultant. Revision rates are higher when trainees are not supervised by a scrubbed consultant but remain within internationally recognised acceptable limits.

Aims

The aim of this study was to conduct evidence synthesis on the available published literature of the impact of the training status of the operating surgeon (trainee vs. consultant) on the survival and revision rate of primary hip and knee replacements.

Patients and Methods

We conducted a systematic review according to Cochrane guidelines. Separate searches were performed for hip and knee replacements, with meta-analysis and presentation of results in parallel. We searched MEDLINE and Embase databases from inception to 17 September 2019 and included controlled trials and cohort studies reporting implant survival estimates, or revision rates of hip and knee replacements according to the grade of the operating surgeon. This study was registered with PROSPERO (CRD42019150494).

Background

Polytrauma patients are at high risk of systematic inflammatory response syndrome (SIRS) due to an exaggerated unbalanced immune response that can lead to multiple organ failure and increased mortality. This response is often heightened following acute surgical management as a result, damage-control orthopaedics (DCO) was born. This allows the patient to be stabilised using external fixation allowing physiology to improve. This systematic review aims to compare DCO against early total care (ETC) (<24hrs intramedullary nailing) in polytraumatised patients with femoral shaft fractures using a diagnosis of acute lung injury (ALI) as the primary outcome measure.

Method

A systematic review of MEDLINE, EMBASE, CENTRAL and AMED was carried out to identify all English language studies comparing ETC versus DCO using ALI as the primary outcome measure. Two authors independently screened the studies and performed data extraction. Risk of bias was assessed using the Cochrane risk of bias tool and the Risk-of-Bias Assessment Tool for Non-randomised Studies.

Background

Clavicle development occurs before the age of 9 in females and 12 in males. Children below the age of 10 with displaced midshaft clavicle fractures recover well with conservative management. However adolescents are more demanding of function and satisfaction following clavicle fractures and may benefit from operative management. Study aims: 1) Perform a systematic review of the current evidence supporting intramedullary fixation of adolescent clavicle fractures. 2) Review current management in a major trauma center (MTC) with a view to assess feasibility for a randomised controlled trial (RCT).

Methods

The MEDLINE, EMBASE and AMED databases were searched in October 2014 to identify all English language studies evaluating intramedullary fixation in children aged 10–18 years using MeSH terms. Data was extracted using a standardised data collection sheet and studies were critically appraised by aid of the PRISMA checklist. All patients aged 9–15 attending an MTC receiving clavicle radiographs in 2014 were retrospectively reviewed for type of fracture, management and outcome.

Background

Hip fracture care has evolved, largely due to standardisation of practice, measurement of outcomes and the introduction of the Best Practice Tariff, leading to the sustained improvements documented by the National Hip Fracture Database (NHFD). The treatment of distal femoral fractures in this population has not had the same emphasis. This study defines the epidemiology, current practice and outcomes of distal femoral fractures in four English centres.

Methods

105 patients aged 50 years or greater with a distal femoral fracture, presenting to four UK major trauma centres between October 2010 and September 2011 were identified. Data was collected using an adapted NHFD data collection tool via retrospective case note and radiograph review. Local ethics approval was obtained.

Objectives

The Sliding Hip Screw (SHS) is commonly used to treat trochanteric hip fractures. Fixation failure is a devastating complication requiring complex revision surgery. One mode of fixation failure is lag screw cut-out which is greatest in unstable fracture patterns and when the tip-apex distance of the lag screw is > 25 mm. The X-Bolt Dynamic Hip Plating System (X-Bolt Orthopaedics, Dublin, Ireland) is a new device which aims to reduce this risk of cut-out. However, some surgeons have reported difficulty minimising the tip-apex distance with subsequent concerns that this may lead to an increased risk of cut-out.

Patients and Methods

We measured the tip-apex distance from the intra-operative radiographs of 93 unstable trochanteric hip fractures enrolled in a randomised controlled trial (Warwick Hip Trauma Evaluation, WHiTE One trial). Participants were treated with either the sliding hip screw or the X-Bolt dynamic hip plating system. We also recorded the incidence of cut-out in both groups, at a median follow-up time of 17 months.

Summary

A single 3D accelerometer is accurate in measuring upper-extremity activity durations, rest periods and intensities, suggesting its feasibility for daily life measurements with patients. Further enhancements are feasible to reduce residual false classifications of intensity from certain activities.

Introduction

Physical activity is an important outcome measure in orthopaedics as it reflects how surgically restored functional capacity is used in daily life. Accelerometer-based activity monitors (AM) are objective, reliable and valid to determine lower extremity activity in orthopaedic patients. However the suitability of a single AM to monitor upper-extremity activity, in terms of quantity and intensity, has not been investigated. This study investigates the suitability and validity of a single AM to measure quantity and intensity of upper-extremity activity.
