OBJECTIVES: The annual incidence of hip fracture is 620 000 in the European Union. The cost of this clinical problem has been estimated at 1.75 million disability-adjusted life years lost, equating to 1.4% of the total healthcare burden in established market economies. Recent guidance from The National Institute for Health and Clinical Excellence (NICE) states that research into the clinical and cost effectiveness of total hip arthroplasty (THA) as a treatment for hip fracture is a priority...

Fungal prosthetic joint infection (PJI) is a rare but severe complication of artroplasty. We report a case of PJI due to azole-resistant Candida albicans successfully treated with combination of prolonged administration of anidulafungin and two-stage joint exchange with insertion of a mega-prosthesis.

OBJECTIVES: To study the correlation between quantitative ultrasound (QUS) expressed as stiffness index (SI) and the risk of aseptic loosening of knee arthroplasty.  METHODS: An observational retrospective controlled study was performed on 85 female patients (mean age: 73.3 years) divided into 2 groups from January 2007 to March 2015 and carried out at the Orthopedic Rehabilitation Unit, Casa di Cura Eremo, Arco, Trento, Italy. Group A included 42 patients who had undergone a revision of knee prosthesis for aseptic-loosening, and group B included 43 age-matched patients who underwent primary replacement of the knee without following aseptic loosening...

Partial knee arthroplasty (PKA), either medial or lateral unicompartmental knee artroplasty (UKA) or patellofemoral arthroplasty (PFA) are a good option in suitable patients and have the advantages of reduced operative trauma, preservation of both cruciate ligaments and bone stock, and restoration of normal kinematics within the knee joint. However, questions remain concerning long-term survival. The goal of this review article was to present the long-term results of medial and lateral UKA, PFA and combined compartmental arthroplasty for multicompartmental disease...

INTRODUCTION: Some studies have proved that Tranexamic acid infusion is associated with a decrease in blood loss during and after surgery. Due to the availability of an oral form of the drug, the rapid and complete absorption of it and ease of administration without need for specific instruments, we evaluated the effectiveness of the oral form in decreasing blood loss after total knee arthroplasty. MATERIALS AND METHODS: In this double-blind, randomized, parallel clinical trial study, we evaluated 53 patients undergoing knee arthroplasty admitted to Ghaem hospital, Mashhad in 2012...

Metal implants corrode and release metal ions, cobalt and chromium, which, in turn, may cause systemic toxicity, mostly in the first few months from implantation of metal-on-metal hip arthroplasty. At the time of delivery, the placenta reduces the passage of cobalt and chromium ions released from metal-on-metal prosthesis. From a biomechanical view point, hip replacement should not be considered a contraindication for pregnancy or for spontaneous delivery, and does not seem to have any negative effects in terms of risk of dislocation, loosening, fracture, or revision surgery, neither negative effects on clinical and functional outcomes...

The posterior instability of the shoulder only represents 4% of the shoulder instabilities. For the diagnosis, the antero-posterior, transtoracic and axilar radiographic projections are recommended. The inverted Hill-Sachs lesion is a fracture caused by compression of the antero-medial part of the humeral head during the posterior dislocation. Its treatment results, at least, controverted. Choosing the treatment of these lesions one of the main factors is the size of the defect in the humeral head. When it is smaller than 20%, the simple reduction usually is enough...

PURPOSE OF THE STUDY: A failure of total hip or knee artroplasty is associated with an increased production of joint fluid. This contains wear particles and host cells and proteins, and is assumed to be involved in the pathogenesis of aseptic loosening and periprosthetic osteolysis. This study investigated the effect of synovial fluid from patients with aseptically failed joint prostheses on osteoblast cultures. MATERIAL AND METHODS: Synovial fluid samples were obtained from patients with failed total joint prostheses (TJP; n=36) and from control patient groups (n = 16) involving cases without TJP and osteoarthritis, without TJP but with osteoarthritis, and with stable TJP...

BACKGROUND AND OBJECTIVES: Vertebral artroplasty with bone cement has its particularities and complications. Most often the procedure is performed under local anesthetic and sedation, but sometimes it is done under subarachnoid or epidural block with morphine to achieve postoperative analgesia. The objective of this report is to discuss the possible complications of vertebroplasties. CASE REPORT: Male patient, 76 years old, presenting pathologic fracture in T12 was admitted for vertebral artroplasty and bone biopsy...

BACKGROUND: Total hip arthroplasty is a successful surgery, that fails at a rate of approximately 10% at ten years from surgery. Causes for failure are mainly aseptic loosening of one or both components partially due to wear of articular surfaces and partially to design. The present analysis aimed to identify risk factors and quantify their effects on aseptic failure. METHODS: Multivariate survival analysis was applied to 4,750 primary total hip arthroplasties performed between 1995 and 2000...

Using ceramic materials it is possible to obtain a number of beneficial mechanical properties such as considerable hardness, good chemical resistance, high tensile strength, and a good fracture toughness. The use of ceramic-on-ceramic as bearing surfaces for hip joint prostheses has been reported to produce a lower wear rate than other combinations (i.e. metal-on-polyethylene and ceramic-on-polyethylene) in total hip artroplasty. These advantages may increase the life expectancy of hip implants and improve the life of patients...
