INTRODUCTION: The distance between the pubic symphysis and sacrococcygeal joint has been noted as an important parameter in evaluating pelvic tilt in an anteroposterior (AP) radiograph. Similarly, pelvic incidence measures the sagittal balance of the pelvis and is influenced by pelvic rotation. The relationship between these 2 parameters is unknown and could affect interpretation of pelvic AP radiographs. METHODS: We reconstructed 248 cadaveric pelvises. Pelvic incidence was measured using a previously validated method...

BACKGROUND: Intraoperative femoral fractures (IFF) during primary total hip arthroplasty (THA) pose a major clinical challenge, and data on mid-term implant performance, functional outcome and patient satisfaction is limited. METHODS: 50 patients who sustained IFFs during primary THA were retrospectively reviewed. A control group of patients who received a primary THA without complications was matched according to gender, age, body mass index and indication for THA...

BACKGROUND: Optimal implant alignment is important for total hip replacement (THR) longevity. Femoral stem anteversion is influenced by the native femoral anteversion. Knowing a patient's femoral morphology is therefore important when planning optimal THR alignment. We investigated variation in femoral anteversion across a patient population requiring THR. METHODS: Preoperatively, native femoral neck anteversion was measured from 3-dimensional CT reconstructions in 1215 patients...

PURPOSE: Early femoral component migration is a useful indicator for identifying implants at risk of failure due to aseptic loosening. The goal of this retrospective study was to identify if anterior approach (AA) treated hips are at a higher risk of failure due to aseptic loosening caused by early migration compared to hips operated on using the traditional posterior approach (PA). METHODS: A total of 388 hips were included in this study, 139 AA and 249 PA treated hips...

INTRODUCTION: The high dislocation rate following revision total hip arthroplasty (THA) has been shown to be significantly reduced by closing the posterior capsule and by the use of large diameter femoral heads. The relative importance of each of these strategies on the rate of dislocation remains unknown. We undertook a study to determine if increasing femoral head diameter, in addition to posterior capsular closure would influence the dislocation rate following revision THA. METHODS: We retrospectively reviewed 144 patients who underwent a revision THA...

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...

BACKGROUND: Although reported results on short stems sound very promising, the occurrence of distal femoral cortical hypertrophy is often observed. The aim of the present study was to report 5-year survival data of a commercially available trochanter sparing short stem and investigate the clinical impact of distal femoral cortical hypertrophy on the outcome. METHODS: 123 total hip arthroplasties were performed on 120 patients from April 2008 to May 2010 (mean age 62, range 29-89 years; 71 hips from male patients, 58%)...

BACKGROUND: While there is an enormous amount of data on various surgical aspects of total hip arthroplasty (THA), there is only limited literature on the health hazards incurred by the surgical team. Since THA surgery produces noise, exposure over a long period of time may lead to gradual hearing loss which is known as noise-induced hearing loss. METHODS: We investigated the noise levels during THA and compared it with the maximum allowed limits at the workplace in the United Kingdom...

INTRODUCTION: Direct Superior Approach (DSA) is a muscle sparing approach for total hip arthroplasty (THA) implemented using special instrumentation. There is a lack of information in the literature concerning DSA with standard instrumentation. MATERIALS AND METHODS: 238 patients were recruited for primary THA by a single surgeon from January 2016 until May 2017. 209 patients underwent THA through DSA approach with non-offset acetabular reamers and femoral broaches...

Hip preservation is one of the fastest growing fields in orthopaedics and indications of intra-articular procedures are well established. In the last decade, extra-articular procedures have gained momentum and arthroscopic solutions to peri-articular hip pathologies have been offered. It should be noted that many of these pathologies are well-treated conservatively and only those who fail conservative management should be treated operatively. These indications can be divided into 5 categories: greater trochanteric pain syndrome; internal hip snapping; anterior inferior iliac spine/sub-spine impingement; sciatic nerve entrapment; and proximal hamstring injuries...

BACKGROUND: Leg-length discrepancy (LLD) is a frequent and recurring issue after total hip arthroplasty (THA). It can lead to discomfort and litigation due to the patient's perception of this inequality. PURPOSE: The aim of this study was to evaluate the functional impact of postoperative LLD and length correction in patients after primary THA. We hypothesised that clinical outcomes are inversely correlated to length correction and residual discrepancy. METHODS: In a prospective cohort, we included 121 patients undergoing unilateral primary THA...

INTRODUCTION: In contrast to cemented hip prostheses, the effect of washing the bone bed with jet-lavage prior to insertion of cementless stem components in primary hip arthroplasty (THA) is unclear. Jet-lavage potentially decreases the risk of fat embolisation during rasping and stem insertion and might help in avoiding bacterial contamination. An earlier animal study has shown less debris and better-organised trabecular structure of new bone when jet-lavage was used. We hypothesised that the primary stability of cementless femoral stems implanted after jet-lavage of the femoral canal prior to stem insertion would improve with earlier stabilisation, as measured with Radiostereometry (RSA), compared with insertion without prior jet-lavage...

INTRODUCTION: Debate over the ideal agent for venous thromboembolism (VTE) prophylaxis after total hip arthroplasty (THA) has led to changes in prescribing trends of commonly used agents. We investigate variation in utilisation and the differences in VTE incidence and bleeding risk in primary THA after administration of aspirin, warfarin, enoxaparin, or factor Xa inhibitors. METHODS: 8829 patients were age/sex matched from a large database of primary THAs performed between 2007 and 2016...

INTRODUCTION: Heterotopic ossification may develop after major hip surgeries, thus preventive strategies including radiation therapy and non steroid anti-inflammatory drugs are commonly employed. There are certain concerns regarding the effects of radiation therapy on implant loosening and carcinogenesis. Our study aims to evaluate whether radiation therapy results in implant loosening or radiation-induced tumours in the long term. PATIENTS AND METHODS: This was a prospective study including 97 high-risk patients for heterotopic ossification who underwent total hip arthroplasty...

OBJECTIVES: Traction force widens the joint space during hip arthroscopy. It is unclear how much the traction force varies and if it is related to the joint space widening. Main goal of our study was to measure the amount of force needed to widen the hip joint. Second goal was to study the relation between this force and the amount of joint space widening. METHODS: Traction force was measured in 27 patients (of whom 24 female, mean age 41) during arthroscopy. Measurements were performed before the procedure, after vacuum seal release and after capsulotomy...

BACKGROUND: This paper presents a parametric investigation into the effect of femoroacetabular impingement (FAI) and developmental dysplasia of the hip (DDH) on the sphericity of the femoral supra-equatorial region and acetabulum. METHODS: Radiographic parameters from x-rays, sphericity calculations and visualisation and joint contact area and pressure from FE models of 10 DDH, FAI and normal hips were analysed and compared both within and between hip groups. RESULTS: The sphericity of the acetabulum and femoral head of both the DDH and FAI groups was found to be less than that for normal hips but the variation in sphericity was greater (range 2...

INTRODUCTION: In arthroplasty surgery, positioning of the components must be accurate and reproducible to avoid complications. Conventional guides are often used to align a component, but they require surgical skill and experience, and are prone to error. To this end, a single-use, size-specific, nylon guide (single-use nylon guide) has been developed for the purpose of increasing the accuracy without adding extra cost to the operation. The effectiveness of this type of guide was evaluated in using a synthetic bone study...

INTRODUCTION: The purpose of this study was to examine the ability of a surgeon to predict survival of a total hip replacement (THR) based on the patient's diagnosis, demographics, postoperative activity level and the surgical technique. METHODS: 4 experienced hip surgeons were asked to predict the longevity of 131 Charnley THRs, performed by the senior author (GH) 22-35 years ago, by providing them with pre- and postoperative radiographs, and data concerning patient's diagnosis, demographics, postoperative activity level and the surgical technique...

BACKGROUND: Psychological distress is presumed to be an important factor that can adversely impact the outcome of orthopaedic procedures. The Distress and Risk Assessment Method (DRAM) is an evaluation tool which assesses psychological distress in patients with low back pain. The purpose of this prospective study was to assess the influence of preoperative psychological distress, as determined by the DRAM score, on the functional outcomes of total joint arthroplasty (TJA). MATERIALS AND METHODS: A prospective study of 61 TJAs was performed at a single institution...
