BACKGROUND: Despite literature to support the use of various cerclage techniques to address intraoperative femoral fractures in total hip arthroplasty, there are limited data to support prophylactic cerclage wiring of the femur during cementless implant placement. This study aims to evaluate the effect of prophylactic calcar cerclage wires on the biomechanical parameters required to produce periprosthetic femoral fractures and on the morphology of these fracture patterns in stable cementless femoral implants...

Morphology and design of ultra-high molecular weight polyethylene (UHMWPE or simply PE) acetabular components used in total hip arthroplasty (THA) have been evolving for more than half a century. Since the late-1990s, there were two major technological innovations in PE emerged from necessity to overcome the wear-induced periprosthetic osteolysis, i.e., the development of highly crosslinked PEs (HXLPEs). There are many literature reporting that radiation crosslinked and remelted/annealed (first-generation) HXLPEs markedly reduced the incidence of osteolysis and aseptic loosening...

Bilateral Neck of Femur (NOF) fractures is relatively rare. Surgery, either osteosynthesis or hemireplacement arthroplasty, is the mainstay of treatment. Significant complications are known to occur in such cases. In this case report, we present the functional outcome of a conservatively treated bilateral NOF fracture at one year, in a 93-year-old man. Our patient, a 93-year-old gentleman, sustained right side NOF fracture in May 2014 and left side NOF fracture in May 2015, both after trivial fall. He did not give consent for surgery considering high operative risk...

OBJECTIVE: The use of metal-on-metal and modular total hip arthroplasty is associated with potentially serious local and systemic complications. The primary aim of this study was to identify the prevalence of a pseudotumor in asymptomatic patients with a particular metal-on-metal hip prosthesis after a minimum follow-up of 5 years using ultrasound evaluation. A secondary purpose was to identify associations between the presence of pseudotumor and serum metal ion levels following implantation...

BACKGROUND: Acetabular impaction bone grafting aims to restore anatomy in hip revision surgery. This is an effective but expensive and time-consuming technique. Usually, the articular cartilage is removed from the femoral head allograft. We aimed to reproduce the same results retaining the cartilage of the allograft. METHODS: Eighty acetabular revisions using impacted morselized bone graft retaining the articular cartilage and a cemented cup were studied retrospectively...

BACKGROUND: Sarcopenia, osteoporosis and osteoarthritis are the most frequent musculoskeletal disorders affecting older people. The main aim of this study was to test the hypothesis that the balance between BMPs and myostatin pathways regulates the age-related muscle degeneration in OP and OA patients. To this end, we investigated the relationship among the expression of BMP-2/4-7, myostatin and phosphorylated Smads1-5-8 and the muscle quality, evaluated in term of fibers atrophy and satellite cells activity...

INTRODUCTION: Rotational acetabular osteotomy (RAO), a joint-conserving surgery in which the femoral head coverage by autologous cartilage is improved to achieve joint stability, is one of the most common joint-conserving surgeries for acetabular dysplasia of the hip in adult patients. Favorable outcome of RAO for pre- and initial coxarthrosis has been reported with middle- to long-term observation; however, surgery should be selected for advanced coxarthrosis. The objective of this study was to investigate the long-term clinical outcomes and radiological arthritis changes in patients who were treated with RAO and could be followed for 15 years or longer, and to investigate the joint conservation rate by preoperative arthritis stage...

INTRODUCTION: The dual-mobility cup (DMC) was introduced in 1979. Due to lack of referenced publications, this interesting and innovating concept was ignored during close to 20 years. However, 180 studies (level III or IV) have now been published. Evidence-based medicine is based on level I studies. Over the past three decades, the role of national registries developed with the intention of surveying orthopaedic implants. In 2012, we developed, registered, and implemented a specific database for contemporary DMC...

An ageing population, increased physical activity and obesity are identified as lifestyle changes that are contributing to the ongoing growth in the use of in-vivo prosthetics for total hip and knee arthroplasty. Cobalt-chromium-molybdenum (Co-Cr-Mo) alloys, due to their mechanical properties and excellent biocompatibility, qualify as a class of materials that meet the stringent functional requirements of these devices. To cost effectively assure the required dimensional and geometric tolerances, manufacturers rely on high-precision machining...

Total knee arthroplasty and total hip arthroplasty are 2 of the most commonly performed elective orthopaedic procedures. They are remarkably successful in relieving pain and improving function in individuals with advanced, symptomatic arthritis. Since, in addition to providing benefits, these procedures pose risks, it is important to provide clinicians with guidance in determining which patients should undergo total joint replacement surgery. The development of the RAND approach in 1986 and its application to total hip and knee replacement have enabled clinicians, payers, and others to assess the appropriateness of past and current procedures for particular patients...

INTRODUCTION: Little information is available regarding the rate of prosthetic joint infections (PJIs) in patients undergoing carpal tunnel release (CTR) without antibiotic prophylaxis. Hand surgeons should be aware of patients' history of arthroplasty. METHODS: All patients who underwent CTR at our institution between 2012 and 2014 were identified and their charts were reviewed to identify those who had a history of total hip, knee, and/or shoulder arthroplasty...

Intraoperative cell salvage, whereby shed surgical blood is recovered for autologous reinfusion, is frequently used during hip arthroplasty because of the potential for significant blood loss. The following cases describe 2 instances in which chromium and cobalt particles from patients' metal-on-metal hip implants were identified within the blood recovery system. Results of heavy metal testing during the second case suggest that the use of a leukocyte reduction filter effectively reduces metal concentrations to below normal circulating levels...

Background. Interest in arthroplasty techniques for periarticular or intra-articular fractures in the elderly/osteoporotic patient continues to rise, including for geriatric acetabular fractures. In line with this, many acetabular fracture surgeons are now undertaking acute total hip arthroplasty in elderly/osteoporotic patients. Little is known however of the outcomes of this procedure, beyond the first year after surgery. Questions/Purposes. We determined the clinical outcomes of a series of elderly osteoporotic patients (mean age at surgery 77...

BACKGROUND: The recent experiences with adverse local tissue reactions have highlighted the need to establish what are normal serum levels of cobalt (Co), chromium (Cr), and titanium (Ti) after hip arthroplasty. METHODS: Serum Co, Cr, and Ti levels were measured in 80 nonconsecutive patients with well-functioning unilateral total hip arthroplasty and compared among 4 bearing surfaces: ceramic-on-ceramic (CoC); ceramic-on-polyethylene (CoP); metal-on-polyethylene (MoP), and dual mobility (DM)...
