INTRODUCTION: In total hip arthroplasty (THA), local adverse reaction to metal debris (ARMD) may be caused by abnormal metal ion release from a metal-on-metal (MoM) bearing, or by wear and corrosion of the implant's modular junction. The aim of this study was to compare ion levels and rate of ARMD between patients sharing the same MoM bearing but 1 group having monoblock stems versus another having modular stems. MATERIALS AND METHODS: Whole blood cobalt (Co) and chromium (Cr) ion concentrations, ARMD rate, revision rate, and function measured by UCLA and WOMAC scores were compared between groups...

BACKGROUND: Untreated developmental hip dysplasia may result in pain, loss of function and is a common cause of osteoarthritis (OA). The periacetabular osteotomy (PAO) was developed to relieve symptoms and postpone further degeneration of the hip. We aimed to assess preoperative clinical and radiographic prognostic factors and evaluate survivorship of PAO after medium-term follow-up of 7.4 (2-15) years. METHODS: 59 patients (69 hips) operated with a PAO through an anterior intrapelvic approach from 1999 to 2011 were retrospectively identified...

INTRODUCTION: Patients presenting with hip diseases often have coexisting spine disorders, a condition that is termed "hip-spine syndrome." However, few reports have evaluated total spinal alignments in patients with coxalgia. In this study, we retrospectively examined the relationship between several clinical and x-ray parameters of the hip joints and spinal alignment in patients with coxalgia. METHODS: 100 patients with coxalgia (24 men, 76 women; average age, 60...

INTRODUCTION: Periprosthetic hip fractures (PPFX) are serious complications that result in increased morbidity, mortality and healthcare costs. Decreasing hospital readmissions has been a recent healthcare focus, but little is known about the overall costs associated with PPFX or the risk factors associated with readmissions. We investigated patient demographics, treatment types, 30- and 90-day readmission rates, direct costs, and patient risk factors associated with PPFX readmission...

PURPOSE: The management of severe acetabular bone deficiency and a stable femoral stem can be a challenging problem in revision hip surgery. Replacement of both the acetabular and femoral component in elderly patients can increase perioperative risks without the certainty of a better functional outcome. We report the long-term outcome of reinforcement rings in isolated acetabular revision to determine whether this procedure allows hip function restoration and implant longevity. METHODS: A retrospective study was conducted to evaluate the long-term results of isolated acetabular revision in thirty patients with a mean age of 70...

BACKGROUND: Free radicals formed in the cross-linking process may over time alter the mechanical properties of highly cross-linked polyethylene. Vitamin E-infused highly cross-linked polyethylene was therefore developed to achieve low wear-rate and good mechanical properties in the long term. AIM: To present 6-year results from the initial randomised controlled trial. PATIENTS AND METHODS: We measured wear and periacetabular bone remodelling in cementless total hip arthroplasty; 32- or 36-mm Biolox Delta heads and vitamin E-infused highly cross-linked polyethylene (E-Poly) were used...

INTRODUCTION: Dislocation of large-diameter head (LDH) metal-on-metal (MoM) total hip arthroplasty (THA) or hip resurfacing arthroplasty (HRA) is a rare complication. This study aimed to determine the incidence and risk factors for dislocation of LDH MoM THAs and HRAs. METHODS: This retrospective analysis considered 4038 cementless LDH MoM THAs and HRAs, 3207 THAs in 2912 patients and 831 HRAs in 757 patients. The end of follow-up was revision due to dislocation...

INTRODUCTION: Sexual activity is often an important component of life. To date, no studies have examined sexual activity before and after total hip arthroplasty (THA) in male patients with ankylosing spondylitis (AS). The purpose of the current study was to evaluate the effect of THA on sexual activity and to explore the most commonly reported and comfortable coital position for male AS patients with hip involvement. METHODS: Data from 31 male AS patients who underwent THA for hip involvement were retrospectively reviewed...

INTRODUCTION: This matched cohort study aims to determine whether the presence of a spinal arthrodesis (SA) compromises outcome of total hip arthroplasty (THA) and whether the outcome is better if THA is performed before- (THA-1st ) or after- SA (THA-2nd ). METHODS: This is a single centre, multi-surgeon, review of prospective data. Thirty-seven patients (47 hips) that had SA and 1° THA(s), formed the cases (26 THA-1st ; 21 THA-2nd ). Most cases had 1-level SA ( n  =  24)...

INTRODUCTION: Radiological inclination (RI) is determined in part by operative inclination (OI), which is defined as the angle between the cup axis or handle and the sagittal plane. In lateral decubitus the theatre floor becomes a surrogate for the pelvic sagittal plane. Critically at the time of cup insertion if the pelvic sagittal plane is not parallel to the floor either because the upper hemi pelvis is internally rotated or adducted, RI can be much greater than expected. We have developed a simple Pelvic Orientation Device (POD) to help achieve a horizontal pelvic sagittal plane...

INTRODUCTION: Previous studies indicate a familial predisposition for developmental dysplasia of the hip (DDH), especially among first-degree relatives. This study investigated the association between unilateral or bilateral periacetabular osteotomy (PAO), family history of DDH and the degree of relationship with relatives with DDH. MATERIAL AND METHODS: This cross-sectional study consisted of 815 consecutive patients undergoing PAO from 1998 to 2016. Information regarding unilateral or bilateral PAO, gender and age at the time of surgery was obtained from the clinical PAO database at Aarhus University Hospital, Denmark...

BACKGROUND: During total hip replacement (THR), subchondral acetabular bone cysts are either left alone or treated by filling with autologous bone graft. We hypothesized that subchondral cysts would consolidate spontaneously over time without compromising the midterm survival of the implant. METHODS: We retrospectively screened the anteroposterior hip radiographs of 731 consecutive patients who underwent primary THR between January 2006 and April 2009. Patients were included in the current study if they had acetabular subchondral bone cysts visible radiographically that had been left alone during THR...

BACKGROUND: According to previous gait analyses, insertion of a total hip arthroplasty (THA) will improve the range of hip flexion-extension but not to normal. Use of short stems could have a potential to improve the motion by preservation of more bone and muscular attachments. We evaluated whether a short femoral stem resulted in improved hip motion compared to a conventional stem in patients who underwent 1-stage bilateral THA. The most painful hip was randomised to either design and the 2nd hip was operated with the design not used on the 1st side...

BACKGROUND: Cadaveric and clinical studies suggest surgical release of the short external rotators is sometimes necessary to improve exposure during total hip arthroplasty (THA) using an anterior approach. The purpose of this study was to determine the impact of those surgical releases on gait following THA. METHODS: 15 patients undergoing THA using an anterior approach, anterior approach with surgical releases, or posterior approach underwent 3-D gait analysis preoperatively, and at 6 and 12 weeks postoperatively...
