BACKGROUND: In total hip arthroplasty with computer navigation assistance, cup orientation is generally determined according to the coordinate system relative to the functional pelvic plane (FPP). However, there is a large difference in the cup anteversion between a posterior pelvic tilt relative to the computed tomography (CT) table in the sagittal plane and anterior pelvic tilt, even when the cup is set at the same orientation angle according to each FPP. The present study analysed this difference from the viewpoint of 3-dimensional (3D) coverage of the acetabular component (3D coverage) to determine how the 3D acetabular coverage is altered with changes in pelvic sagittal tilt...

BACKGROUND: The need for revision surgery after hip resurfacing arthroplasty (HRA) is more prevalent for women than for men. However, there is a paucity of information to explain this observation. We aimed (1) to determine sex-specific risk factors leading to revision surgery; and (2) to correlate these risk factors to the dominant modes of failure of HRA. METHODS: 1101 patients (1375 consecutive hips) including 292 women (355 hips) and 809 men (1020 hips) with a mean age of 51...

BACKGROUND: Dual-modular femoral components with exchangeable cobalt-chrome neck segments have had higher than expected failure rates due to corrosion and adverse local tissue reaction (ALTR). Complications, survival rates and early clinical outcomes of revision surgery for the treatment of corrosion and ALTR as a result of these implants are underreported. METHODS: We identified 44 cases of revision THA for corrosion and ALTR resulting from the same dual modular stem...

INTRODUCTION: Intraoperative radiographic evaluation during total hip arthroplasty (THA) has shown to improve the accuracy of acetabular component placement, however, differences in interpretation based on radiographic technique has not been established. This study aims to determine if differences exist in the interpretation of acetabular component abduction and anteversion between different radiographic projections. METHODS: 55 consecutive direct anterior THAs in 49 patients were prospectively enrolled...

INTRODUCTION: In situ fixation (ISF) is currently still the 'gold standard' treatment for slipped capital femoral epiphysis (SCFE) and has shown acceptable results at mid-term follow-up. This study aims to evaluate functional, clinical and radiographic long-term outcomes after this procedure. METHODS: We reviewed 64 SCFE patients (76 SCFE hips) treated with ISF between 1983 and 1998. 82.9% were stable hips and 17.1% unstable according to Loder's definition. Initial radiographs demonstrated a mild slip in 50%, moderate in 41...

INTRODUCTION: Metal-on-metal (MoM) total hip arthroplasties (THAs) have been linked with increased incidence of pseudotumours and revision rate. magnetic resonance imaging (MRI) is useful in diagnosing adverse reaction to metal debris (ARMD) disease but it is not known if MRI findings correlate with cup position. PATIENTS AND METHODS: From a cohort of 79 MoM THA, 34 MRI studies were available. MRI was classified according to Anderson classification. Mean follow-up was 7...

BACKGROUND: Periprosthetic bone remodelling may increase fracture risk and deplete bone stock around hip implants. These changes are in part caused by implant design, advocating an early evaluation of bone remodelling properties of new implants. This can be done by repeated dual-energy x-ray absorptiometry (DXA) measurements. We know that radiopaque cement falsely elevates bone mineral density (BMD) in single measurements, however, its impact on repeated measurements, i.e. BMD changes is unexplored...

INTRODUCTION: To maximise limb-length discrepancy (LLD) resolution during total hip arthroplasty (THA) for untreated developmental hip dysplasia or septic hip sequelae, THA following limb lengthening was introduced using different methods. We aimed to evaluate 2-stage THA results following limb lengthening via skeletal traction after extensive soft tissue release. METHOD: In total, 24 hips with severe LLD in 10 men and 14 women (mean age, 49.6 ± 15.2 years) underwent 2-stage THA and were followed thereafter (mean 6...

INTRODUCTION: Mental health and patient expectation have been identified as key predictors of recovery following THA; however, there is limited literature examining the effects of social support and marital status on patient-reported outcomes (PROs). METHODS: Data were prospectively collected and retrospectively reviewed for patients who underwent THA between July 2008 and January 2016. Patients were included if they underwent primary THA during this period and if they had documented preoperative marital status of married, divorced, or never married...

INTRODUCTION: Noise in ceramic-on-ceramic (CoC) total hip arthroplasty (THA) is a potential symptom of abnormal bearing wear. Squeaking and other prosthetic hip noises are multi-factorial phenomena that can be analysed and may provide prognostic information. METHODS: 46 patients with noisy CoC bearings were investigated using X-ray, computed tomography and joint fluid analysis, and classified into either high or low risk of ceramic liner fracture groups according to previously published guidelines...

BACKGROUND: Non-oncologic total femoral replacement (TFR) is utilised as a limb-salvage option in the setting of massive bone loss during revision total hip arthroplasty (THA) and total knee arthroplasty (TKA). However, complication rates, including infection and reoperation, remain a concern. METHODS: In this study, 16 consecutive TFRs from a single institution with an average clinical follow-up of 4 years were retrospectively reviewed. Indications for TFR, previous surgeries, implants used, complications, reoperations, and ambulatory status at final follow-up were recorded...

AIM: Intertrochanteric fractures account for almost 50% of hip fractures.Nonunion and malunion of these fractures are relatively uncommon. This study reviews the outcome of 31 cases of intertrochanteric fracture failures. An algorithm for the management of these injuries is also proposed. METHODS: 19 patients with intertrochanteric malunion and 12 patients with non-union were included in this study. Treatment of these injuries was initiated according to the algorithm proposed in this study...

INTRODUCTION: This study sought to determine the effect that malnutrition, defined as hypoalbuminemia, has on hip fracture patients treated with total hip arthroplasty (THA). Specifically, we evaluated: (1) demographics and perioperative data; (2) postoperative complications; and (3) re-operation rates. METHODS: The National Surgical Quality Improvement Program database was utilised to identify hip fracture patients who underwent THA from 2008 to 2015. Propensity scores were calculated for the likelihood of having a preoperative albumin measurement...

INTRODUCTION: Trunnion geometry is known to vary between hip systems. Trunnionosis and the impact of trunnion design on total hip arthroplasty (THA) survival, has gained attention as a failure mechanism. We sought to report the differences in patient-reported outcome measures (PROMs) between the most commonly utilised modern THA trunnions. METHODS: We reviewed primary unilateral THA patients from May 2007 to October 2011. The most frequently used stems were included...

PURPOSE: To determine if boney morphology influences the anatomic location of hip fractures in elderly patients. METHODS: All patients with hip fractures between 2008 and 2012 who had hip radiographs taken prior to the fracture were reviewed. Fractures were classified as intracapsular or extracapsular and hip morphology was measured on the pre-fracture x-rays. Hip morphology was determined by alpha angle, lateral central edge angle, acetabular index, neck-shaft angle, hip axis length, femoral neck diameter, Tönnis classification for hip osteoarthritis (OA) and the presence of a crossover sign...

OBJECTIVES: The posterior approach in total hip arthroplasty (THA) often requires dissection of the short external rotators (SERs), which could increase the postoperative dislocation rate. The reattachment of the dissected SERs has been reported to reduce the dislocation rate, while such repair generally causes progression of muscle atrophy. 1 of the suggested causes of atrophy is reduced blood flow to the repaired SERs. The present study aimed to measure the blood flow of the SERs before dissection (pre-tenotomy) and after reattachment (post-reattachment) during the posterior approach in THA...

BACKGROUND: Surgeons are increasingly using larger femoral head sizes in total hip arthroplasty (THA) to improve stability and reduce the rate of dislocation, 1 of the leading causes of revision surgery. Large ceramic head sizes up to 48 mm can now be used with monoblock acetabular components. National registries have shown promising results at short-term with large diameter ceramic-on-ceramic THA, with very low revision rates. This study reports on the average 3-year follow up of a press-fit monoblock large diameter acetabular shell with a pre-assembled ceramic liner, with emphasis on the radiographic outcome, complications related to the implantation of the cup, and the patient's clinical outcome...
