ABSTRACT

Background: Many orthopaedic surgeons use a 'standard' stem offset length, typically 37.5 mm and 44 mm for females and males respectively, in total hip arthroplasty. With increasingly personalized surgery, 'standard' one-size-fits-all stem lengths may be outdated. This study aims to test whether pre-operative templating affects stem length choice and whether 'standard' stem sizes are therefore outdated. Methods: We performed a retrospective chart review of all total hip arthroplasty patients using Stryker's Exeter cemented femoral hip system in our centre between 2016 and 2020. Demographic and surgical data were collected. Data from surgeons who templated pre-operatively were compared to data from those who did not. Results: 780 patients were included (309 male, 471 female), average age 71.4 years (range 23-96). We found a significant difference between male and female offset lengths; more males had an offset length of 44 mm and more females had an offset length of 37.5 mm (p = 0.004). Among surgeons who did not template pre-operatively, 20.6% of female patients and 10.3% of male patients had other 'non-standard' offset lengths. Among surgeons who did template pre-operatively, the proportion of both female and male patients who had other 'non-standard' offset lengths was significantly higher (43.1% and 23.4%, respectively p < 0.05). Conclusions: The difference between templating and non-templating surgeons' stem choice revealed significant individual variability between males and females. 'Standard' offset lengths for males and females were still used in the majority of our cohort. However, with the emergence of mainstream robotic arthroplasty, we feel that pre-operative templating has become a minimum standard.

ABSTRACT

Anterior dislocations of the native hip are rare injuries, and normally a result of high energy trauma such as road traffic accidents. Delays in reduction of over 12 hours have been shown to increase the risk of avascular necrosis to the head of the femur significantly. We report the case of an elderly man who sustained an anterior dislocation of his native hip following a fall. The case highlights that prompt appropriate management can lead to excellent clinical outcomes.

ABSTRACT

We describe the case of a young 27-year-old Caucasian female who presented in the third trimester of her first pregnancy with sudden and severe suprapubic and left-sided hip pain without history of trauma. She was eventually diagnosed with two insufficiency fractures of the pelvis. The underlying diagnosis was pregnancy-related osteoporosis. Her baby was delivered successfully at term, with an elective caesarean section. The diagnosis was eventually made using a magnetic resonance imaging scan. Pregnancy-related osteoporosis is relatively rare, and cases of patients presenting with insufficiency fractures of this condition are rarer still. Our case raises the importance of considering this diagnosis in females in the later stages of pregnancy, with severe sudden hip or pelvis pain. The patient gave informed written consent for the publication of this case.

ABSTRACT

BACKGROUND: Rehabilitation after surgery of the injured anterior cruciate ligament (ACL) is crucial for satisfactory outcomes. Many trials have investigated this process after ACL reconstruction. The treatment of acute ACL ruptures with a repair technique has recently regained interest, although very little information is available about appropriate rehabilitation for such patients. The objective of this review was to evaluate studies on rehabilitation following ACL repair. METHODS: A systematic review of the literature following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted for patients undergoing a rehabilitation programme after ACL repair. The review has been registered on the International Prospective Register of Systematic Reviews (PROSPERO, Registration number: CRD42020173450). Elements of rehabilitation care we included in our strategy are postoperative bracing, home-based rehabilitation, strengthening exercises, proprioception and neuromuscular training. We searched PubMed, CINAHL, EMBASE, and the Cochrane Library for randomised trials of any form investigating rehabilitation protocols after repair of the injured ACL. Two reviewers independently assessed eligibility of trials. RESULTS: No trials were included. Available literature of lower evidence was included for discussion. CONCLUSIONS: No information is available from randomised trials to indicate whether there is any difference between rehabilitation protocols for patients who have undergone primary ACL repair.

ABSTRACT

The coronavirus disease 2019 (COVID-19) pandemic has had significant implications for society, with the introduction of restrictive social measures. Antibody tests provide a way of identifying patients who have been previously exposed to the virus and thus may have a degree of immunity. This is important in the development of public health policy, as local and national bodies seek to relax social restrictions in an attempt to mitigate the socioeconomic impact of the pandemic. This article explores the essential statistical concepts used to interpret the findings of diagnostic investigations, with examples illustrated using COVID-19 antibody tests.

ABSTRACT

INTRODUCTION: Neck of femur fractures are common in the comorbid, often anticoagulated, elderly. Non-vitamin K antagonist oral anticoagulants (NOACs) may affect patient outcomes. We aimed to evaluate whether hip fracture patients admitted on warfarin or NOAC therapy were at risk of operative delay, prolonged length of stay, or increased mortality. METHODS: We collected data for 845 patients admitted to our centre between October 2014 and December 2016. Multivariable linear regression analysis was performed to test the association between warfarin and NOAC therapy on time to surgery and length of stay. Variables in the regression model were age, sex, admission AMTS, pre-fracture mobility, ASA score, fracture type, and operation type. Fisher's exact test was used to evaluate whether warfarin or NOAC therapy delayed surgery beyond 36 or 48 hours, or decreased 30-day, 6-month, or 12-month survival. RESULTS: Time to surgery was delayed in anticoagulated patients (p = 0.028). NOAC therapy was independently associated with increased time to surgery beyond 36 hours (p = 0.001), although not beyond 48 hours (p = 0.355), whereas warfarin therapy was not associated with either. Anticoagulation did not increase length of stay (p = 0.331). Warfarin therapy significantly reduced 30-day survival (p = 0.007), but NOAC therapy did not (p = 0.244). Neither warfarin nor NOAC therapy affected further survival. CONCLUSIONS: NOAC therapy delays time to surgery beyond the NHS England 'Best Practice Tariff' in hip fracture patients. We aim to prospectively investigate long-term outcomes. Without a NOAC antidote, policy must change to ensure time-appropriate surgery for patients on NOACs. Preoperative involvement of the haematology team is essential.
