INTRODUCTION: Cultures of deep synovial biopsies remain an important tool in diagnosing periprosthetic joint infection, a devastating complication following total hip arthroplasty (THA). Recent reports of unexpected positive intraoperative cultures in aseptic revision arthroplasty, however, challenge the validity and interpretation of these cultures. The aim of this study was to evaluate the contamination risk of synovial biopsy cultures collected intraoperatively during primary THA of healthy subjects...

INTRODUCTION: The purpose of this study was to compare acetabular cup position for 2 cohorts of total hip arthroplasty (THA) patients who had a direct anterior approach. METHODS: 100 THA cases were performed with an anterior approach using intraoperative fluoroscopy (IF) to aid in cup positioning. Another group of 100 cases underwent THA with an anterior approach without the use of any fluoroscopy. Postoperative abduction and anteversion angles were measured using Martell's hip analysis software...

INTRODUCTION: Total hip arthroplasty (THA) is a very successful procedure. Revision THA is becoming increasingly common. Recent developments to improve outcomes include the development of large trabecular metal (TM) acetabular cups and augments. There is a paucity of data on the benefit of these new techniques. METHODS: A single-centre retrospective review consisting of a radiological review of post-op revision THA anteroposterior pelvis. Data collection was performed using the Irish National Orthopaedic Register (INOR) and from a previous project...

INTRODUCTION: Trabecular Titanium is an advanced cellular solid structure, composed of regular multiplanar hexagonal interconnected cells that mimic the morphology of the trabecular bone. This biomaterial demonstrated improved mechanical properties and enhanced osteoinduction and osteoconduction in several in vitro and in vivo studies. The aim of this study was to assess Trabecular Titanium osseointegration by measuring periacetabular changes in bone mineral density (BMD) with dual-emission X-ray absorptiometry (DEXA)...

INTRODUCTION: Acetabular liner dissociation is a complication exclusive to modular designs. We present a single surgeon series of 8 polyethylene liner dissociations with the Pinnacle Acetabular System (DePuy Orthopaedics) from over 4,750 cases. We also present a review of the literature and data from the UK National Joint Registry (NJR) on dissociation in total hip arthroplasty (THA). METHODS: The Pinnacle Acetabular System has been used exclusively by the senior author since April 2003, and to date 5,882 have been implanted (837 ceramic liners, 4,751 polyethylene liners (1,606 Enduron/3,145 Marathon) and 294 metal liners)...

BACKGROUND: The 2009 NHS Blood and Transplant national comparative audit on blood use following primary total hip arthroplasty (THR) highlighted that preoperative anaemia was common and undertreated. They recommended that hospitals have a written policy for treating anaemia preoperatively. In our centre, we found that preoperative optimisation of anaemia, significantly reduced blood transfusion rate to <5%. The 2015 national audit showed that even though 48% of patients received tranexamic acid, 85% of patients required transfusion...

OBJECTIVE: To evaluate the viability and integrity of fresh frozen bulk femoral head allografts obtained from the institutional bone bank that were used to reconstruct severe acetabular defects and to validate the SPECT/CT method which gives both anatomical and functional data for this purpose. METHODS: We retrospectively reviewed 9 patients (6 female, 3 male; mean age 63.6 years). Preoperative and postoperative leg lengths, existence of the Trendelenburg sign, range of motion of the hip, visual analogue score (VAS), Harris Hip Score (HHS) and any complication were assesed at each follow-up...

BACKGROUND: Patient satisfaction, as measured by Press Ganey (PG) surveys, partially determines reimbursement rates. Knowing what influences these scores can lead to higher reimbursement for total hip arthroplasty (THA) surgeons. Currently, it is unknown whether gender biases exist in satisfaction surveys post-THA. Therefore, we asked: (i) which PG survey factors most influence hospital ratings among men and women after THA; and (ii) is there a difference in survey element responses and overall hospital ratings between men and women post-THA? METHODS: We queried the PG database for patients who underwent THA from November 2009 to January 2015, which yielded 692 patients (277 men, 415 women)...

BACKGROUND: Current studies demonstrate controversy regarding the relationship between cigarette smoking and osteonecrosis of the femoral head (ONFH). METHODS: We conducted a meta-analysis to evaluate the association between smoking and ONFH. Relevant articles published before September 2016 were identified by a systematic search of EMBASE and MEDLINE via Ovid. Summary odds ratios (OR) were calculated using random effects models, and study quality was assessed using a modified Newcastle-Ottawa scale...

Impingement syndromes are increasingly recognised as significant causes of hip pain and dysfunction. A broad spectrum of intraarticular and extraarticular conditions has been implicated in their pathophysiology. Physical examination is often inconclusive as clinical findings may be unclear or misleading, often simulating other disorders. With current improvements in imaging techniques and better understanding of hip impingement related pathomechanisms, these entities can be accurately diagnosed. In addition, preoperative imaging has allowed for targeted treatment planning...

BACKGROUND: Periprosthetic femoral shaft fractures are a significant complication after total hip arthroplasty (THA). Plate osteosynthesis has been the mainstay of treatment around well-fixed stems. Nonunions are a rare and challenging complication of this fixation method. We report the outcomes of a novel orthogonal plating surgical technique for Vancouver B1 and C-type periprosthetic fractures that previously failed open reduction internal fixation (ORIF). METHODS: A retrospective review identified all patients with Vancouver B1/C THA periprosthetic femoral nonunions from 2010 to 2015...

INTRODUCTION: Total hip arthroplasty (THA) in the young is challenging. The purpose of this study was to retrospectively determine the clinical, radiographic, and polyethylene wear rate of relatively young patients. METHODS: We evaluated the outcome of consecutive patients receiving primary THA who were under 40 years of age with a minimum 10-year follow-up. Indications for THA in these patients were osteoarthritis due to developmental dysplasia of the hip joint (9 hips), osteonecrosis of the femoral head (7 hips), juvenile idiopathic arthritis (2 hips), and osteoarthritis due to Perthes disease (1 hip)...
