BACKGROUND: The purpose of this observational study was to evaluate serum levels of 25-OH-D in patients scheduled to undergo elective hip or knee arthroplasty. We hypothesised that 25-OH-D level is an independent risk factor for length of stay in orthopaedic patients after elective hip or knee arthoplasty. MATERIALS AND METHODS: 25-OH-D levels were measured in 1083 patients admitted to an orthopaedic surgery department to undergo elective hip or knee arthroplasty...

OBJECTIVE: The severe pain and disability associated with osteoarthritis often motivate individuals to undergo arthroplastic surgery. However, a significant number of surgical patients continue to experience pain following surgery. Prior research has implicated both the hypothalamic-pituitary-adrenal (HPA) axis and sympathetic nervous system (SNS) in the sensitization of pain receptors and chronic pain conditions. This study uses a prospective, observational, cohort design to examine whether physiological stress responses before and after surgery could predict post-operative pain severity...

INTRODUCTION: In cases of temporomandibular joint (TMJ) ankylosis, interposition arthroplasty allows return of functional jaw movements. In order to improve the facial appearance, distraction osteogenesis is the treatment of choice, and may be timed either as a pre-arthroplastic, simultaneous or post-arthroplastic procedure. This study was planned to compare the treatment outcomes of pre-arthroplastic distraction (PAD) and simultaneous arthroplastic distraction (SAD) to establish the better treatment modality in terms of improvement in function and aesthetics...

Venous thromboembolism (VTE) is one of the severe complications of total hip arthroplasty (THA) and total knee arthroplasty (TKA). The incidence of VTE could be reduced if preventive antithrombotic medicines are used; however, the incidence of bleeding may increase. Rivaroxaban is a factor Xa inhibitor that prevents VTE after THA or TKA. This study is designed to confirm the efficacy and safety of rivaroxaban in Taiwan. This is a retrospective database study based on the data of 6996 patients provided by the Taiwan National Health Insurance Research Database from 2008 to 2012...

PURPOSE: The purpose of this study was to identify the frequency and type of intra-operative periprosthetic fractures and to describe risk factors in a single tertiary, public hospital, so that these events could be prevented, even among less experienced surgeons. METHODS: This is a cross-sectional study, based on medical records and imaging exams from the archives of a public, tertiary hospital, from April 1998 to October 2013. All consecutive patients submitted to total hip arthroplasty (THA) in the study period were evaluated, excluding unipolar or bipolar arthroplasty, surgery for the osteosynthesis of periprosthetic fractures, surgical procedure to clean infection site without component substitution and not arthroplastic surgery...

Hip arthrosis, primary or secondary, is an osteoarthritic degenerative process that affects the hip joint. Primary hip arthrosis has an unknown etiology, and secondary hip arthrosis has well defined causes; of these causes, some are known to lead to arthrosis of the hip in the young age patient. The surgical treatment aims either to preserve the patient’s hip joint, or to replace the joint. The most commonly used procedure at this time is the total hip arthroplasty. The femoral component may have a short or a long stem...

Osteonecrosis of the second metatarsal head is often attributed to Freiberg's disease. We describe the case of a 27-year-old Taiwanese male soldier with persistent painful disability of the right forefoot of 9 months' duration, but no history of trauma. A series of radiographs suggested the diagnosis of late-stage Freiberg's disease. The lesion was treated with interpositional arthroplasty using a palmaris longus tendon graft, in a modification of the traditional interpositional arthroplastic technique for treating Freiberg's disease...

PURPOSE: Periprosthetic infection after total hip arthroplasty is a devastating complication. A two-stage protocol with the temporary insertion of an antibiotic-laden cement spacer is the gold standard treatment for chronic infections (Clinics (Sao Paulo) 62:99-108, 2007; Clin Orthop Relat Res 427:37-46, 2004; J Arthroplast 14:175-181, 1999; Clin Orthop Relat Res 467:1848-1858, 2009; J Arthroplast 20:874-879, 2005; J Arthroplast 24: 607-613, 2009; Clin Orthop Relat Res 469:1009-1015, 2011; Hip Int 20:26-33, 2010; J Arthroplast 24:1051-1060, 2009; J Bone Joint Surg Br 91:44-51, 2009)...

UNLABELLED: Research concerning the impact of trauma history on individuals' ability to cope with subsequent events is mixed. While many studies find that trauma history increases vulnerability for conditions such as post-traumatic stress disorder and chronic pain, others reveal that there are benefits associated with moderate levels of stress (e.g. development of coping skills). OBJECTIVE: The present study investigated whether the experience of prior traumatic stressors would serve as a risk or resilience factor based on physical and emotional outcomes among patients recovering from total knee replacement surgery (TKR)...

INTRODUCTION: One in eight of all total hip replacements requires revision within 10 years, 60% because of wear-related complications. The bearing surfaces may be made of cobalt/chromium, stainless steel, ceramic, or polyethylene. Friction between bearing surfaces and corrosion of non-moving parts can result in increased local and systemic metal concentrations. OBJECTIVES: To identify and systematically review published reports of systemic toxicity attributed to metal released from hip implants and to propose criteria for the assessment of these patients...

In this review we have evaluated the state of the art of CNT/UHMWPE and graphene/UHMWPE composites from four different points of view: mechanical properties, chemical stability, wear resistance and biocompatibility. The performance of these new carbonaceous composites allows us to conclude that these materials have overcome a first step on the way to developing into an alternative to the current HXLPEs used in orthopedic applications.

ABSTRACTPatients undergoing arthroplastic surgery of the lower limbs and those with multiple injuries have a high risk of thromboembolism. Enoxaparin is a highly effective antithrombotic drug that is well tolerated and without the need for monitoring. Numerous controlled trials in these patient groups have demonstrated enoxaparin to be at least as effective as heparin in reducing the occurrence of deep vein thrombosis while showing a tendency towards lower risk of bleeding complications; therefore, enoxaparin is recommended as thromboprophylaxis in patients undergoing major hip or knee surgery or suffering from multiple trauma...

BACKGROUND CONTEXT: Proximal congenital radial-ulnar synostosis (PCRUS) is defined by the development before birth of a bony bridge between the radius and ulna, usually at the proximal level, which blocks forearm rotation. This anomaly is rarely reported in the medical literature, because of its low prevalence, and treatment usually yields unsatisfactory results. The most commonly used surgical interventions are: forearm repositioning osteotomies with derotation of the radius and ulna, segmental resections of the middle third of the radius with muscular interposition, resection of the synostosis with the interposition of fatty tissue, tendons or fascia lata and resection of the proximal radius along with the transfer of the distal extensor carpi ulnaris tendon on the lateral edge of the radius...
