To identify factors influencing clinicians’ decisions to undertake a nonoperative hip fracture management approach among older people, and to determine whether there is global heterogeneity regarding these factors between clinicians from high-income countries (HIC) and low- and middle-income countries (LMIC). A SurveyMonkey questionnaire was electronically distributed to clinicians around the world through the Fragility Fracture Network (FFN)’s Perioperative Special Interest Group and clinicians’ personal networks between 24 May and 25 July 2021. Analyses were performed using Excel and STATA v16.0. Between-group differences were determined using independent-samples Aims
Methods
To report our experience with trunnion corrosion following metal-on-polyethylene
total hip arthroplasty, in particular to report the spectrum of
presentation and determine the mean time to presentation. We report the presenting symptoms and signs, intraoperative findings,
and early results and complications of operative treatment in nine
patients with a mean age of 74 years (60 to 86). The onset of symptoms
was at a mean of seven years (3 to 18) after index surgery.Aims
Patients and Methods
The aim of this study was to assess the efficacy of non-selective
and selective non-steroidal anti-inflammatory drugs (NSAIDs) in
preventing heterotopic ossification (HO) after total hip arthroplasty
(THA). A thorough and systematic literature search was conducted and
29 studies were found that met inclusion criteria. Data were extracted
and statistical analysis was carried out generating forest plots.Aims
Methods
The National Hip Fracture Database (NHFD) publishes hospital-level risk-adjusted mortality rates following hip fracture surgery in England, Wales and Northern Ireland. The performance of the risk model used by the NHFD was compared with the widely-used Nottingham Hip Fracture Score. Data from 94 hospitals on patients aged 60 to 110 who had hip fracture surgery between May 2013 and July 2013 were analysed. Data were linked to the Office for National Statistics (ONS) death register to calculate the 30-day mortality rate. Risk of death was predicted for each patient using the NHFD and Nottingham models in a development dataset using logistic regression to define the models’ coefficients. This was followed by testing the performance of these refined models in a second validation dataset.Objectives
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:
We examined the one-year risk of symptomatic
venous thromboembolism (VTE) following primary total hip replacement
(THR) among Danish patients and a comparison cohort from the general
population. From the Danish Hip Arthroplasty Registry we identified
all primary THRs performed in Denmark between 1995 and 2010 (n =
85 965). In all, 97% of patients undergoing THR received low-molecular-weight
heparin products during hospitalisation. Through the Danish Civil
Registration System we sampled a comparison cohort who had not undergone
THR from the general population (n = 257 895). Among the patients
undergoing THR, the risk of symptomatic VTE was 0.79% between 0
and 90 days after surgery and 0.29% between 91 and 365 days after
surgery. In the comparison cohort the corresponding risks were 0.05%
and 0.12%, respectively. The adjusted relative risks of symptomatic
VTE among patients undergoing THR were 15.84 (95% confidence interval
(CI) 13.12 to 19.12) during the first 90 days after surgery and
2.41 (95% CI 2.04 to 2.85) during 91 to 365 days after surgery,
compared with the comparison cohort. The relative risk of VTE was
elevated irrespective of the gender, age and level of comorbidity
at the time of THR. We concluded that THR was associated with an increased risk of
symptomatic VTE up to one year after surgery compared with the general
population, although the absolute risk is small.
Femoroacetabular impingement is a cause of hip pain in adults and is potentially a precursor of osteoarthritis. Our aim in this study was to determine the prevalence of bilateral deformity in patients with symptomatic cam-type femoroacetabular impingement as well as the presence of associated acetabular abnormalities and hip pain. We included all patients aged 55 years or less seen by the senior author for hip pain, with at least one anteroposterior and lateral pelvic radiograph available. All patients with dysplasia and/or arthritis were excluded. A total of 113 patients with a symptomatic cam-impingement deformity of at least one hip was evaluated. There were 82 men and 31 women with a mean age of 37.9 years (16 to 55). Bilateral cam-type deformity was present in 88 patients (77.8%) while only 23 of those (26.1%) had bilateral hip pain. Painful hips had a statistically significant higher mean alpha angle than asymptomatic hips (69.9° vs 63.1°, p <
0.001). Hips with an alpha angle of more than 60° had an odds ratio of being painful of 2.59 (95% confidence interval 1.32 to 5.08, p = 0.006) compared with those with an alpha angle of less than 60°. Of the 201 hips with a cam-impingement deformity 42% (84) also had a pincer deformity. Most patients with cam-type femoroacetabular impingement had bilateral deformities and there was an associated acetabular deformity in 84 of 201 patients (42%). This information is important in order to define the natural history of these deformities, and to determine treatment.
Little is known about the efficacy of graduated compression stockings in preventing venous thromboembolism after hip surgery. We conducted a prospective, randomised single-blind study to determine whether the addition of compression stockings to fondaparinux conferred any additional benefit. The study included 874 patients, of whom 795 could be evaluated (400 in the fondaparinux group and 395 in the fondaparinux plus compression stocking group). Fondaparinux was given post-operatively for five to nine days, either alone or combined with wearing stockings, which were worn for a mean 42 days (35 to 49). The study outcomes were venous thromboembolism, or sudden death before day 42. Duplex ultrasonography was scheduled within a week of day 42. Safety outcomes were bleeding and death from venous thromboembolism. The prevalence of deep-vein thrombosis was similar in the two groups 5.5% (22 of 400) in the fondaparinux group and 4.8 (19 of 395) in the fondaparinux plus stocking group (odds ratio 0.88, 95% confidence interval 0.46 to 1.65, p = 0.69). Major bleeding occurred in only one patient. The addition of graduated compression stockings to fondaparinux appears to offer no additional benefit over the use of fondaparinux alone.
We report a retrospective review of the incidence of venous thromboembolism in 463 consecutive patients who underwent primary total hip arthroplasty (487 procedures). Treatment included both total hip replacement and hip resurfacing, and the patients were managed without anticoagulants. The thromboprophylaxis regimen included an antiplatelet agent, generally aspirin, hypotensive epidural anaesthesia, elastic compression stockings and early mobilisation. In 258 of these procedures (244 patients) performed in 2005 (cohort A) mechanical compression devices were not used, whereas in 229 (219 patients) performed during 2006 (cohort B) bilateral intermittent pneumatic calf compression was used. All operations were performed through a posterior mini-incision approach. Patients who required anticoagulation for pre-existing medical problems and those undergoing revision arthroplasty were excluded. Doppler ultrasonographic screening for deep-vein thrombosis was performed in all patients between the fourth and sixth post-operative days. All patients were reviewed at a follow-up clinic six to ten weeks after the operation. In addition, reponse to a questionnaire was obtained at the end of 12 weeks post-operatively. No symptomatic calf or above-knee deep-vein thrombosis or pulmonary embolism occurred. In 25 patients in cohort A (10.2%) and in ten patients in cohort B (4.6%) asymptomatic calf deep-vein thromboses were detected ultrasonographically. This difference was statistically significant (p = 0.03). The regimen followed by cohort B offers the prospect of a low incidence of venous thromboembolism without subjecting patients to the higher risk of bleeding associated with anticoagulant use.
