We aimed to use data from a randomized controlled trial (RCT) comparing the sliding hip screw vs. intramedullary nailing (IMN) for trochanteric fractures to examine complication rates between those managed with a short vs. long IMN. This is a secondary analysis using one arm of an RCT of patients ≥18 years with trochanteric fractures. We examined differences in fracture-related (femoral shaft fracture, implant failure,

This trial aims to assess the effectiveness of quality improvement collaboratives as a technique to introduce large-scale change and improve outcomes for patients undergoing primary elective total hip or total knee arthroplasty. 41 NHS Trusts that did not have; a preoperative anaemia screening and optimisation pathways, or a methicillin sensitive Staphylococcus Aureus (MSSA) decolonisation pathway, in place were randomised to one of two parallel collaboratives in a two arm, cluster randomised controlled trial. Each collaborative focussed on implementing one of these two preoperative pathways. Collaboratives took place from May 2018 to November 2019. 27 Trusts completed the trial. Outcome data were collected for procedures between November 2018 and November 2019. Co-primary outcomes were perioperative blood transfusion (within 7 days of surgery) and deep

Introduction. Wound complications following revision total hip arthroplasty (THA) are associated with an increased risk of superficial and deep infections. Closed incision negative-pressure therapy (ciNPT) has been reported to decrease this risk. This study's purpose was to assess if ciNPT decreases the rate of wound complications following revision THA versus a conventional, silver-impregnated dressing. Methods. This was a single center, randomized controlled trial of patients undergoing both septic and aseptic revision THA. Patients received either ciNPT or a silver-impregnated dressing (control) for 7 days. Wound complications within 90 days of the procedure were recorded, including:
Aims. Intravenous dexamethasone has been shown to reduce immediate postoperative pain after total hip arthroplasty (THA), though the effects are short-lived. We aimed to assess whether two equivalent perioperative split doses were more effective than a single preoperative dose. Methods. A total of 165 patients were randomly assigned into three groups: two perioperative saline injections (Group A, placebo), a single preoperative dose of 20 mg dexamethasone and a postoperative saline injection (Group B), and two perioperative doses of 10 mg dexamethasone (Group C). Patients, surgeons, and staff collecting outcome data were blinded to allocation. The primary outcome was postoperative pain level reported on a ten-point Numerical Rating Scale (NRS) at rest and during activity. The use of analgesic and antiemetic rescue, incidence of postoperative nausea and vomiting (PONV), CRP and interleukin-6 (IL-6) levels, range of motion (ROM), length of stay (LOS), patient satisfaction, and the incidence of

Introduction. The obesity epidemic is a growing problem and must be considered with the projected increased demand for total hip arthroplasty (THA). Previous studies have reported increased complication rates after THA in the obese population, which has led to hesitation in offering surgery to this population. Moreover, some insurers are denying coverage for morbidly obese patients. While many consider obesity a “modifiable” risk factor, very few patients with advanced osteoarthritis have successfully lost substantial weight. The experience of centers that utilize systematic preoperative risk stratification tools and standardized postoperative total joint pathways may be underrepresented in prior studies. The aim of this study is to describe one surgeon's experience performing THA in morbidly and super-obese patient populations using an institutional preoperative Risk Stratification Tool (RST) and total joints pathway. Methods. We conducted a retrospective review of patients undergoing primary THA between May 2014 and December 2017 performed by a single surgeon at a tertiary care referral center. All patients were assessed preoperatively using an institutional RST and had a minimum of 90-day postoperative follow up. Patients were stratified by body mass index (BMI, kg/m. 2. ): non-obese (BMI < 30), obese (30–34), severely obese (35–39), morbidly obese (40–44), and super-obese (≥ 45). Primary outcomes were inpatient and 90-day complications. Continuous and binary parameters were analyzed by Kruskal-Wallis and Fisher exact tests. Logistic regression was additionally utilized to evaluate outcomes by BMI cohort. Results. A consecutive series of 368 patients met inclusion criteria across all BMI cohorts. There was significant variation with respect to age (P=0.001), BMI (P<0.001), diabetes (P=0.008), ASA class (P<0.001), and anesthesia type (P=0.003) (Table 1). Variation among BMI cohorts was also identified for several operative and postoperative parameters, including longer operative and in-room time and greater length of stay (P<0.001) (Table 2). Compared to non-obese patients, super-obese patients had 20.1 greater odds of return to OR within 90 days for superficial
Introduction.
The aim of this study was to compare the early postoperative mortality and morbidity in older patients with a fracture of the femoral neck, between those who underwent total hip arthroplasty (THA) and those who underwent hemiarthroplasty. This nationwide, retrospective cohort study used data from the Japanese Diagnosis Procedure Combination database. We included older patients (aged ≥ 60 years) who underwent THA or hemiarthroplasty after a femoral neck fracture, between July 2010 and March 2022. A total of 165,123 patients were included. The THA group was younger (mean age 72.6 (SD 8.0) vs 80.7 years (SD 8.1)) and had fewer comorbidities than the hemiarthroplasty group. Patients with dementia or malignancy were excluded because they seldom undergo THA. The primary outcome measures were mortality and complications while in hospital, and secondary outcomes were readmission and reoperation within one and two years after discharge, and the costs of hospitalization. We conducted an instrumental variable analysis (IVA) using differential distance as a variable.Aims
Methods
Total hip arthroplasty (THA) using the direct anterior approach (DAA) is undertaken with the patient in the supine position, creating an opportunity to replace both hips under one anaesthetic. Few studies have reported simultaneous bilateral DAA-THA. The aim of this study was to characterize a cohort of patients selected for this technique by a single, high-volume arthroplasty surgeon and to investigate their early postoperative clinical outcomes. Using an institutional database, we reviewed 643 patients who underwent bilateral DAA-THA by a single surgeon between 1 January 2010 and 31 December 2018. The demographic characteristics of the 256 patients (39.8%) who underwent simultaneous bilateral DAA-THA were compared with the 387 patients (60.2%) who underwent staged THA during the same period of time. We then reviewed the length of stay, rate of discharge home, 90-day complications, and readmissions for the simultaneous bilateral group.Aims

The World Health Organization (WHO) and the Centre
for Disease Control and Prevention (CDC) recently published guidelines
for the prevention of surgical site infection. The WHO guidelines,
if implemented worldwide, could have an immense impact on our practices
and those of the CDC have implications for healthcare policy in
the United States. Our aim was to review the strategies for prevention of periprosthetic
joint infection in light of these and other recent guidelines. Cite this article:
Louis Pasteur once said that: “Fortune favours
the prepared mind.” As one of the great scientists who contributed
to the fight against infection, he emphasised the importance of
being prepared at all times to recognise infection and deal with
it. Despite the many scientific discoveries and technological advances,
such as the advent of antibiotics and the use of sterile techniques,
infection continues to be a problem that haunts orthopaedic surgeons
and inflicts suffering on patients. The medical community has implemented many practices with the
intention of preventing infection and treating it effectively when
it occurs. Although high-level evidence may support some of these
practices, many are based on little to no scientific foundation.
Thus, around the world, there is great variation in practices for
the prevention and management of periprosthetic joint infection. This paper summaries the instigation, conduct and findings of
a recent International Consensus Meeting on Surgical Site and Periprosthetic
Joint Infection. Cite this article:
Periprosthetic joint infection (PJI) is a devastating
complication which can follow a total joint arthroplasty (TJA).
Although rare, this ongoing threat undermines the success of TJA,
a historically reputable procedure. It has haunted the orthopedic
community for decades and several ongoing studies have provided
insights and new approaches to effectively battle this multilayered
problem.
