This study assessed the impact of COVID-19 on hip and distal femur fracture patient outcomes across three successive UK lockdown periods over one year. A single-centre retrospective cohort study was performed at an acute NHS Trust. Hip and distal femur fracture patients admitted within the first month from each of the three starting dates of each national lockdown were included and compared to a control group in March 2019. Data were collected as per the best practice tariff outcomes including additional outcomes as required. Data collection included COVID-19 status, time to theatre, 30-day mortality, presence of acute kidney injury (AKI) and pneumonia, and do not attempt cardiopulmonary resuscitation (DNACPR) status. Data were analyzed using an independent-samples Aims
Methods
We studied the safety and efficacy of multimodal thromboprophylaxis in patients with a history of venous thromboembolism (VTE) who undergo total hip arthroplasty (THA) within the first 120 postoperative days, and the mortality during the first year. Multimodal prophylaxis includes discontinuation of procoagulant medications, VTE risk stratification, regional anaesthesia, an intravenous bolus of unfractionated heparin prior to femoral preparation, rapid mobilization, the use of pneumatic compression devices, and chemoprophylaxis tailored to the patient’s risk of VTE. Between 2004 to 2018, 257 patients with a proven history of VTE underwent 277 primary elective THA procedures by two surgeons at a single institution. The patients had a history of deep vein thrombosis (DVT) (186, 67%), pulmonary embolism (PE) (43, 15.5%), or both (48, 17.5%). Chemoprophylaxis included aspirin (38 patients), anticoagulation (215 patients), or a combination of aspirin and anticoagulation (24 patients). A total of 50 patients (18%) had a vena cava filter in situ at the time of surgery. Patients were followed for 120 days to record complications, and for one year to record mortality.Aims
Methods
Failure of irrigation and debridement (I&D) for prosthetic joint infection (PJI) is influenced by numerous host, surgical, and pathogen-related factors. We aimed to develop and validate a practical, easy-to-use tool based on machine learning that may accurately predict outcome following I&D surgery taking into account the influence of numerous factors. This was an international, multicentre retrospective study of 1,174 revision total hip (THA) and knee arthroplasties (TKA) undergoing I&D for PJI between January 2005 and December 2017. PJI was defined using the Musculoskeletal Infection Society (MSIS) criteria. A total of 52 variables including demographics, comorbidities, and clinical and laboratory findings were evaluated using random forest machine learning analysis. The algorithm was then verified through cross-validation.Aims
Methods
To analyse the effectiveness of debridement and implant retention
(DAIR) in patients with hip periprosthetic joint infection (PJI)
and the relationship to patient characteristics. The outcome was
evaluated in hips with confirmed PJI and a follow-up of not less
than two years. Patients in whom DAIR was performed were identified from our
hip arthroplasty register (between 2004 and 2013). Adherence to
criteria for DAIR was assessed according to a previously published
algorithm.Aims
Patients and Methods
There is currently limited information available
on the benefits and risks of extended thromboprophylaxis after hip fracture
surgery. SAVE-HIP3 was a randomised, double-blind study conducted
to evaluate the efficacy and safety of extended thromboprophylaxis
with the ultra-low molecular-weight heparin semuloparin compared
with placebo in patients undergoing hip fracture surgery. After
a seven- to ten-day open-label run-in phase with semuloparin (20
mg once daily subcutaneously, initiated post-operatively), patients
were randomised to once-daily semuloparin (20 mg subcutaneously)
or placebo for 19 to 23 additional days. The primary efficacy endpoint
was a composite of any venous thromboembolism (VTE; any deep-vein
thrombosis and non-fatal pulmonary embolism) or all-cause death until
day 24 of the double-blind period. Safety parameters included major
and clinically relevant non-major bleeding, laboratory data, and
treatment-emergent adverse events (TEAEs). Extended thromboprophylaxis
with semuloparin demonstrated a relative risk reduction of 79% in
the rate of any VTE or all-cause death compared with placebo (3.9% Cite this article:
