Dual mobility (DM) is most often used by surgeons to reduce instability in high risk patients. NJR data on DM has not demonstrated a reduction in all cause revision and has reported an increase in revision for peri-prosthetic fracture (PPF). The aim of our study was:. Report outcome of DM used in high-risk patients including non-revision re-operations (dislocation & PPF). Comparison with conventional bearing THA (cTHA) with local, national and NJR benchmarking data. Retrospective cohort assessment of falls risk for patients receiving DM. Prospective F/U of a DM implant since 2016 and enrolled into Beyond Compliance (BC). Primary outcome measure all-cause revision with secondary outcome including any re-operation and Oxford Hip Score (OHS). All patients were risk stratified and considered high risk for instability. Complications were identified via hospital records, clinical coding linkage, NJR and BC. Benchmarking data for comparison was obtained from same data sources we also considered all B type PPF that occurred with cemented polished taper stem (PTS). 159 implants in 154 patients with a mean age 74.0 years and a maximum F/U of 6.7 years. Survivorship for all-cause revision 99.4% (95% CI 96.2–99.8). One femoral only revision. Mean gain in OHS 27.4. Dislocation rate 0.6% with a single event. Patients with a PTS rate of Type B PPF 2.1% requiring revision/fixation. Compared to cTHA this cohort was significantly older (74.0 vs 68.3 years), more co-morbidity (ASA 3 46.5% vs 14.4%) and more non-OA indications (32.4% vs 8.5%). Relative risks for dislocation 0.57 (95%CI 0.08–4.1) and PPF 1.75 (95%CI 0.54–5.72). Every patient had at least one risk factor for falling and >50% of cohort had 4 or more risk factors using NICE tool. The selective use of DM in high-risk patients can reduce the burden of instability. These individuals are very different to the “average” THA patient. A “perfect storm” is created using a high-risk implant combination (DM & PTS) in high-risk falls risk population. This re-enforces the need to consider all patient and implant factors when deciding bearing selection

Aims. The coronavirus disease (COVID)-19 pandemic forced an unprecedented period of challenge to the NHS in the UK where hip fractures in the elderly population are a major public health concern. There are approximately 76,000 hip fractures in the UK each year which make up a substantial proportion of the trauma workload of an average orthopaedic unit. This study aims to assess the impact of the COVID-19 pandemic on hip fracture care service and the emerging lessons to withstand any future outbreaks. Methods. Data were collected retrospectively on 157 hip fractures admitted from March to May 2019 and 2020. The 2020 group was further subdivided into COVID-positive and COVID-negative. Data including the four-hour target, timing to imaging, hours to operation, anaesthetic and operative details, intraoperative complications, postoperative reviews, COVID status, Key Performance Indicators (KPIs), length of stay, postoperative complications, and the 30-day mortality were compiled from computer records and our local National Hip Fracture Database (NHFD) export data. Results. Hip fractures and inpatient falls significantly increased by 61.7% and 7.2% respectively in the 2020 group. A significant difference was found among the three groups regarding anaesthetic preparation time, anaesthetic time, and recovery time. The mortality rate in the 2020 COVID-positive group (36.8%) was significantly higher than both the 2020 COVID-negative and 2019 groups (11.5% and 11.7% respectively). The hospital stay was significantly higher in the COVID-positive group (mean of 24.21 days (SD 19.29)). Conclusion. COVID-19 has had notable effects on the hip fracture care service: hip fracture rates increased significantly. There were inefficiencies in theatre processes for which we have recommended the use of alternate theatres. COVID-19 infection increased the 30-day mortality and hospital stay in hip fractures. More research needs to be done to reduce this risk. Cite this article: Bone Joint Open 2020;1-9:530–540

The purpose of this study is to understand the lived experience of mature patients who undergo a periacetabular osteotomy (PAO), a major surgical procedure that treats symptomatic hip dysplasia by realigning the acetabulum. Our aim was to better understand how the PAO impacted the lives of the patients and their families, with a long-term goal of improving the experience. We utilized a phenomenological approach with in-depth, semi-structured interviews to investigate the experience of seven women, ages 25–40, who underwent a PAO. A modified intensity sampling method coupled with criterion sampling was used. Inclusion criteria included raising at least one child and being in a committed relationship with a partner. Analysis of interview transcripts revealed eight themes, each of which falls into one of three chronological periods. From the start of dysplasia symptoms until meeting the PAO surgeon: (1) frustration with symptoms disrupting daily activities, (2) discouragement from misdiagnoses and lack of explanation for symptoms, and (3) fear of the PAO operation. During the PAO decision-making process: (1) the importance of education regarding the PAO procedure and full understanding of its purpose, and (2) the utility of social media to learn from past PAO patients in order to feel more confident about the decision to undergo PAO. Post-operation through recovery: (1) feelings of helplessness, isolation and difficulty asking for help, (2) relying heavily on family and/or close friends for assistance, and (3) desire for more support and communication from the healthcare team. Our findings suggest that the psychosocial burden of PAO surgery is great, with major impact on the patient and family. Many important issues lie outside the scope of what healthcare teams currently address

Aim. Left sided hip fractures are more common but no obvious cause has been identified. Left handedness has previously been associated with an increased risk of fracture for a number of sites but to the best of our knowledge no association between handedness and hip fracture has previously been reported. Methods. 2 separate 6-month prospective reviews of hip fracture patients aged over 65 years-of-age were conducted at 2 different hospitals. Handedness was dete2rmined at the time of admission. The second review focused on the use of walking aids. Patients with a previous cerebrovascular accident, neurological condition or contralateral hip prosthesis were excluded due to increased balance problems and falls risk. Results. Hand dominance was recorded for 339 patients; 304 right and 35 left. 91 patients were excluded. Of the remaining 248 patients more than twice as many (2.06 times) fractured their hip on the side of their non-dominant hand. For left handed individuals this increased to 4.6 times. Walking aid use was recorded for 102 patients. For patients using no walking aids, a Zimmer frame or 2 walking sticks; equal numbers of patients sustained right and left hip fractures. While 97.7% of patients using 1 walking stick did so in their dominant hand, sustaining 84% contralateral hip fractures. Conclusions. The direction in which people fall and the causes of hip fractures are clearly multi-factorial. However there is a clear association between hand dominance and the side of hip fracture, particularly in left handed individuals. Walking aids also play a role with 97.7% of patients using a walking stick in their dominant hand resulting in 84% contralateral hip fractures. By being aware of this association it may be possible to target both patient education and physiotherapy potentially reducing the number of patient falls and associated hip fractures

Aims

The Exeter V40 femoral stem is the most implanted stem in the National Joint Registry (NJR) for primary total hip arthroplasty (THA). In 2004, the 44/00/125 stem was released for use in ‘cement-in-cement’ revision cases. It has, however, been used ‘off-label’ as a primary stem when patient anatomy requires a smaller stem with a 44 mm offset. We aimed to investigate survival of this implant in comparison to others in the range when used in primary THAs recorded in the NJR.

Aims

To describe the epidemiology of acetabular fractures including patient characteristics, injury mechanisms, fracture patterns, treatment, and mortality.

Aims

This study reports the results of 38 total hip arthroplasties (THAs) in 33 patients aged less than 50 years, using the JRI Furlong hydroxyapatite ceramic (HAC)-coated femoral component.

Aims

Cementing in arthroplasty for hip fracture is associated with improved postoperative function, but may have an increased risk of early mortality compared to uncemented fixation. Quantifying this mortality risk is important in providing safe patient care. This study investigated the association between cement use in arthroplasty and mortality at 30 days and one year in patients aged 50 years and over with hip fracture.

Aims

A revision for periprosthetic joint infection (PJI) in total hip arthroplasty (THA) has a major effect on the patient’s quality of life, including walking capacity. The objective of this case control study was to investigate the histological and ultrastructural changes to the gluteus medius tendon (GMED) in patients revised due to a PJI, and to compare it with revision THAs without infection performed using the same lateral approach.

Aims

The number of revision arthroplasties being performed in the elderly is expected to rise, including revision for infection. The primary aim of this study was to measure the treatment success rate for octogenarians undergoing revision total hip arthroplasty (THA) for periprosthetic joint infection (PJI) compared to a younger cohort. Secondary outcomes were complications and mortality.

Aims

The aim of this study was to determine both the incidence of, and the reoperation rate for, postoperative periprosthetic femoral fracture (POPFF) after total hip arthroplasty (THA) with either a collared cementless (CC) femoral component or a cemented polished taper-slip (PTS) femoral component.

Aims

This study aimed to determine clinical outcomes; relationships between postoperative anterior, lateral, and posterior acetabular coverage and joint survival; and prognostic factors for joint survival after transposition osteotomy of the acetabulum (TOA).

Aims

This work aimed at answering the following research questions: 1) What is the rate of mechanical complications, nonunion and infection for head/neck femoral fractures, intertrochanteric fractures, and subtrochanteric fractures in the elderly USA population? and 2) Which factors influence adverse outcomes?

Aims

The aim of this study was to explore the functional results in a fitter subgroup of participants in the Hip Fracture Evaluation with Alternatives of Total Hip Arthroplasty versus Hemiarthroplasty (HEALTH) trial to determine whether there was an advantage of total hip arthroplasty (THA) versus hemiarthroplasty (HA) in this population.

Introduction. In recent years the relationship between hyponatraemia and bone metabolism, falls and fractures has become more established. In this study hyponatraemia was an independent risk factor for increased post-operative mortality on multivariate analysis. Patients/Materials & Methods. This study retrospectively evaluates the prevalence of hyponatraemia (plasma sodium <135 mmol/l) in 3897 patients undergoing operative treatment for hip fracture and the relationship between hyponatraemia and mortality in these patients. Results. Median age at admission was 83 years. Hyponatraemia was present in 19.1% of patients with hip fracture on admission, 29.5% of patients within the first 24 hours post-operatively and 20% of patients at discharge. There was a significant association between hyponatraemia and time from admission to surgery indicating that patients admitted with hyponatraemia waited longer. Median follow-up time was 863 (range 0 – 4352) days. There were 2460 deaths (63.1% of the original 3897 patients) prior to the censor date. A total of 1144 patients (29.4% of the original 3897 patients) died within 12 months following discharge. Median survival following surgery was 39 weeks. Median time to death for patients with and without hyponatraemia on admission was 34 months (SE 1.7months) and 41 months (SE 2.5 months) respectively (p = 0.003). Median time to death for patients with and without hyponatraemia within 24 hours post-operatively was 35 months (SE 2.5 months) and 42 months (SE 1.7 months) respectively (p = 0.004). Following elimination of other independent variables associated with increased mortality, hyponatraemia on admission was associated with an increased risk of death (adjusted HR 1.15, p = 0.005). Post-operative hyponatraemia was also associated with an increased risk of death (adjusted HR 1.15, p = 0.006). Conclusion. Hyponatraemia is common in elderly patients with hip fractures both at initial presentation and during admission and is a potentially reversible cause of increased post-operative mortality

Aims

This study aims to assess the feasibility of conducting a pragmatic, multicentre randomized controlled trial (RCT) to test the clinical and cost-effectiveness of an informal caregiver training programme to support the recovery of people following hip fracture surgery.

Aims

The aim of this study was to determine whether national standards of best practice are associated with improved health-related quality of life (HRQoL) outcomes in hip fracture patients.

Aims

To determine if primary cemented acetabular component geometry (long posterior wall (LPW), hooded, or offset reorientating) influences the risk of revision total hip arthroplasty (THA) for instability or loosening.

Aims

Type 2 diabetes mellitus (T2DM) impairs bone strength and is a significant risk factor for hip fracture, yet currently there is no reliable tool to assess this risk. Most risk stratification methods rely on bone mineral density, which is not impaired by diabetes, rendering current tests ineffective. CT-based finite element analysis (CTFEA) calculates the mechanical response of bone to load and uses the yield strain, which is reduced in T2DM patients, to measure bone strength. The purpose of this feasibility study was to examine whether CTFEA could be used to assess the hip fracture risk for T2DM patients.

Aims

Surgical treatment of young femoral neck fractures often requires an open approach to achieve an anatomical reduction. The application of a calcar plate has recently been described to aid in femoral neck fracture reduction and to augment fixation. However, application of a plate may potentially compromise the regional vascularity of the femoral head and neck. The purpose of this study was to investigate the effect of calcar femoral neck plating on the vascularity of the femoral head and neck.
