Aims

Several different designs of hemiarthroplasty are used to treat intracapsular fractures of the proximal femur, with large variations in costs. No clinical benefit of modular over monoblock designs has been reported in the literature. Long-term data are lacking. The aim of this study was to report the ten-year implant survival of commonly used designs of hemiarthroplasty.

Methods

Patients recorded by the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) between 1 September 1999 and 31 December 2020 who underwent hemiarthroplasty for the treatment of a hip fracture with the following implants were included: a cemented monoblock Exeter Trauma Stem (ETS), cemented Exeter V40 with a bipolar head, a monoblock Thompsons prosthesis (Cobalt/Chromium or Titanium), and an Exeter V40 with a Unitrax head. Overall and age-defined cumulative revision rates were compared over the ten years following surgery.

Aims

Despite multiple trials and case series on hip hemiarthroplasty designs, guidance is still lacking on which implant to use. One particularly deficient area is long-term outcomes. We present over 1,000 consecutive cemented Thompson’s hemiarthroplasties over a ten-year period, recording all accessible patient and implant outcomes.

Methods

Patient identifiers for a consecutive cohort treated between 1 January 2003 and 31 December 2011 were linked to radiographs, surgical notes, clinic letters, and mortality data from a national dataset. This allowed charting of their postoperative course, complications, readmissions, returns to theatre, revisions, and deaths. We also identified all postoperative attendances at the Emergency and Outpatient Departments, and recorded any subsequent skeletal injuries.

Introduction and Objective

Evidence in literature is contradicting regarding outcomes of total knee arthroplasty (TKA) in post-traumatic osteoarthritis (PTOA) and whether they are inferior to TKA in primary osteoarthritis (OA). The aim of this review was to find out if any difference exists in the results of TKA between the two indications.

Materials and Methods

The electronic databases MEDLINE, EMBASE, The Cochrane Collaboration, and PubMed were searched and screened in duplicate for relevant studies. The selected studies were further subjected to quality assessment using the modified Coleman method. The primary outcome measure was patient reported outcome, and secondary outcome measures were infection, revision, stiffness, and patella tendon rupture.

Hip fractures in elderly patients are managed at both major trauma centers (MTC) and trauma units (TU). Previous evidence has demonstrated the importance of early surgery to reduce the morbidity and mortality related to the injury. The aim of this study is to compare the ‘time to theatre' and ‘30 day mortality' in TUs versus MTC in UK.

A retrospective review of prospectively collected data on NHFD was performed. The average ‘time to theatre' in hours and ‘30 day mortality' of all hospitals were analysed between January and December 2018. Further subgroup analysis was done to check for any regional variations; in each instance a Shapiro-Wilk test was used to check for normal distribution, followed by a one-way ANOVA with a Tukey's post hoc test.

Data from 158 hospitals in England (ENG), Wales (WAL) and Northern Ireland (NI) were used; 18 of which were MTC. There were 57,936 operative cases in TUs and 8606 in MTC's. The mean time (hours) to surgery from presentation was 32.51 and 32.64 for TUs and MTC respectively (p=0.513).

There was no significant difference in ‘30 day mortality' (p=0.635) between TUs (6%) and 5.7% MTC's (5.7%), MTC's and TUs in ENG, WAL and NI (p=0.555), and MTC and WAL, NI and the different regions of ENG (p=0.209).

A significant difference was observed, between the regional practice for TUs versus MTC's in ENG, WAL and NI (p=0.001) and between MTC's and TUs in WAL, NI and the different regions of ENG (p=0.001), with patients waiting significantly longer in NI for their procedure (mean=60.25 hours, p=0.001)

There was no significant difference in time to surgery or 30 day mortality between TUs and MTC's, demonstrating comparable hip fracture care, despite MTCs need to prioritise more serious injuries.

Aim

This study aimed to identify risk factors for development of deep periprosthetic joint infection (PJI) in patients following surgical treatment of neck of femur fracture.

Method

This study identified a consecutive series of 2,822 (2,052 female, 73%) patients who underwent either hemiarthroplasty (n=1,825, 65%) or fixation (DHS) (n=997, 35%) for fractured neck of femur performed between January 2009 and June 2015 at our institution. Full patient demographics, co-morbidity and peri-operative complication data were determined. The majority of patients were either ASA 2 (n=663, 23%) or ASA 3 (n=1,521, 54%), mean age = 81.3 years (SD 10.3). All patients were followed up post-operatively by a dedicated surgical site infection (SSI) monitoring team in order to identify patients who developed a PJI within 1 year. A stepwise multivariable logistic regression model was used to identify patient and surgical factors associated with increased risk of infection. Predictors with a p-value of <0.20 in the univariate analysis were included in the multivariate analysis.

Aim

The incidence of fractured neck of femur (FNOF) is increasing yearly. Many of these patients undergo hip hemiarthroplasty. High dose dual-antibiotic cement (HDDAC) has been shown to reduce rates of deep surgical site infection (SSI) when compared to the current standard low dose single-antibiotic cement (LDSAC) in a quasi-randomised controlled trial. Some concerns exist regarding the use of HDDAC and the development of resistance. We reviewed cases of infection in LDSAC and HDDAC bone cement with regard to causative organism and resistance profile.

Method

A retrospective analysis was undertaken of all hemiarthroplasties within our trust from April 2008 to December 2014. We identified all patients in this time period who acquired a deep SSI from the trust SSI surveillance database. The infecting organisms and susceptibility patterns were collated for each cement.
