BACKGROUND: To study whether thyroid function was associated with risk of hip or knee replacement due to primary osteoarthritis. METHODS: In a prospective cohort study, data from the second and third survey of the Nord-Trøndelag Health Study were linked to the Norwegian Arthroplasty Register in order to identify total hip or knee replacement as a result of primary osteoarthritis. RESULTS: Among 37 891 participants without previously known thyroid disease we recorded 978 total hip replacements (THRs) and 538 total knee replacements (TKRs) during a median follow-up time of 15...

Osteolysis around joint replacements may develop due to migration of wear particles from the joint space into gaps between the interface bone and the implant where they can accumulate in high concentrations to cause tissue damage. Osteolysis may appear in various postoperative times and morphological shapes which can be generalized into linear and focal. However, there are no clear explanations on the causes of such variations. Patients' degree of sensitivity to polyethylene particles (osteolysis thresholds), the local particle concentration and the access route provided by the interface gaps have been described as determining factors...

INTRODUCTION: Primary synovial osteochondromatosis of the hip is a benign disorder, which is not frequently seen clinically. The characteristic of this disease is proliferation of synovium and formation of loose bodies inside the joint. It is known that only the loose bodies derived from synovium were called synovial osteochondromatosis. Although it can take place in any joint, the knee is most commonly affected, involvement of the hip joint is relatively rare. We report a young man who has multiple synovial osteochondromatosis in his left hip...

BACKGROUND: Aseptic loosening due to bone remodelling processes after total hip replacement is one common cause for revision surgery. In human medicine, dual-energy X-ray absorptiometry (DEXA) is the gold standard for quantitative evaluation of bone mineral density, whereas in veterinary medicine conventional radiography is used for follow-up studies. Recently, a method has been described using digital X-ray images for quantitative assessment of grey scale values of bone contrast. Therefore, the aim of the present study was to evaluate the correlation of bone mineral density (BMD) measured by DEXA with grey scale values (GV) measured in digital X-ray images (RX50, RX66) ex vivo...

INTRODUCTION: In younger patients, ceramic-on-ceramic (CoC) bearing surfaces are usually recommended for total hip replacement (THR) because of their low wear rate and longer expected functional life. Although technical advancements have reduced the risk of ceramic bearings fracture, this complication remains a major concern. CASE DESCRIPTION: We present the case of a 56-year-old patient undergoing 3 revision hip arthroplasties of the right hip due to ceramic liner fractures...

In the United States, long standing deep infections of joint arthroplasty, such as total knee and total hip replacements, are treated with two-stage exchange. This requires the removal of the prior implant, placement of an antibiotic eluting spacer block made of polymethylmethacrylate (PMMA), followed by re-implantation of a new implant after treatment with intravenous antibiotics for six to eight weeks. Unfortunately, the use of PMMA as a spacer material has limitations in terms of mechanical and drug-eluting properties...

BACKGROUND: The strength of the modular fixation between head and stem taper of total hip replacement implants should be sufficient to minimise relative motion and prevent corrosion at the interface. Intraoperatively the components are assembled by impaction with a hammer. It is unclear whether the effective compliance of the patient's body modifies the strength of the taper interface under impaction assembly. The purpose of this study was to assess the influence of the compliance of the patient's body on the taper fixation strength...

Paget's disease of the bone may predispose the development of malignant bone tumors such as osteosarcoma. Giant cell tumor (GCT) as a consequence of Paget's disease is rare. Bone GCT is characterized by rapid growth, the destruction of bone, extension to the surrounding soft tissue and abnormal bone turnover caused by an abnormality of the receptor activator of nuclear factor-κB (RANK)-RANK ligand (RANKL) pathway. Denosumab is a RANK-RANKL inhibitor, which is used to treat osteoporosis and bone GCT. In the current study, a 60-year-old male presented with severe pain located between the right thigh and the knee...

REVIEW
David Hummel
Total hip replacement (THR) is the gold standard treatment of intractable pain from hip dysplasia. THR procedures are divided into 2 main categories: cemented and cementless, with hybrid a combination. The Zurich Cementless THR system uses a combination of press-fit (acetabular component) and locking screw (femoral component) fixation designed to address the main challenge facing cemented systems (aseptic loosening) while providing the benefit of immediate stability with its novel locking screw implantation system for the femoral stem...

Spinal anaesthesia is the most preffered anesthesia technique for total hip replacement, and its complications range from low entity (insignificant) to life threatening. The incidence of neurologic complications after neuraxial anaesthesia is not perfectly clear, although there are several described cases of spinal cord ischaemia. We present a case of unilateral T8-T11 spinal cord ischaemia following L2-L3 spinal anaesthesia for total hip replacement. Magnetic resonance imaging showed a hyperintense T8-T11 signal alteration on the leftside of paramedian spinal cord...

BACKGROUND: Orthopaedics and traumatology departments are dominated by patients with proximal femoral fractures, who represent 20-30% of all patients treated there. The aim of this study was identification and evaluation of factors influencing treatment of proximal femoral fractures. MATERIAL AND METHODS: Between 2008 and 2015, we treated 424 femoral neck fractures and 442 trochanteric fractures in patients over 40 y/o. The impact of fracture location (femoral neck/trochanteric), character (non-displaced/displaced) and the patient's general condition (metrical/biological age, health condition) on qualification and treatment used (fixations/hip pro-sthesis/non-operative) was analyzed...
