BACKGROUND: Little is known about the causes and mechanisms underlying periprosthetic fractures around femoral components particularly in relation to the stem design. In an in vitro study 20 pairs of fresh cadaveric femora were loaded to fracture axially and transversally. FINDINGS: When proximal femoral strain was measured at the time of impaction of cementless stems the load transfer was determined by the underlying anatomy rather than by the shape of the stem, so that the so-called "load transfer" properties - proximal or distal - ascribed to stem designs are a myth...

INTRODUCTION: In our environment, it is increasingly necessary to perform an activity based on scientific evidence and the field of prosthetic surgery should be governed by the same principles. The national arthroplasty registries allow us to obtain a large amount of data in order to evaluate this technique. The aim of our study is to analyse the scientific evidence that supports the primary total knee arthroplasties implanted in Catalonian public hospitals, based on the Arthoplasty Registry of Catalonia (RACat) MATERIAL AND METHODS: A review of the literature was carried out on knee prostheses (cruciate retaining, posterior stabilized, constricted and rotational) recorded in RACat between the period 2005-2013 in the following databases: Orthopedic Data Evaluation Panel, PubMed, TripDatabase and Google Scholar...

With an aging population, distal humerus fractures are becoming an emerging problem. Whereas open reduction and internal fixation has been the treatment of choice, results have not been as conclusive in elderly patients. Over two thirds of the cases in this population present with a highly comminuted articular fracture and poor bone stock, jeopardizing the quality and stability of the construct. Total elbow arthroplasty has gained popularity in the treatment of such fractures, and has shown higher results in terms of pain, function, and patient satisfaction...

Rheumatoid arthritis is a polyarthropathy affecting approximately 1% of the population worldwide. Wrist involvement is observed around 75% of patients, resulting in substantial disability and morbidity. A multidisciplinary approach to management of such patients is undertaken to prevent disease progression, many go on to develop debilitating disease requiring surgical intervention. Total wrist arthroplasty and arthrodesis are the main options available for those with end-stage disease, with arthroplasty preferred due to its ability to preserve a good degree of wrist function...

INTRODUCTION: To improve surgical safety, health systems must identify preventable adverse outcomes and measure changes in these outcomes in response to quality improvement initiatives. This requires understanding of the scope and limitations of available population-level data. To derive literature-based summary estimates of benchmarks of care, we will systematically review and meta-analyse rates of postoperative complications associated with several common and/or high-risk operations performed in five high-income countries (HICs)...

INTRODUCTION: Revision total knee arthoplasty often requires modular implants to treat bone defects of varying severity. In some cases, it may not be clear which module size and implant combination (e.g. sleeve and stem) should be chosen for a specific defect. When balancing implant stability and osseointegration against stress-shielding, it is important to choose an appropriate implant combination in order to match the given level of bone loss. Therefore, the necessity of stems in less extensive tibial defects and the advantage of different stems (lengths and stiffnesses) in combination with large metaphyseal sleeves on implant fixation and bone flexibility using a modular tibial revision knee system, were analyzed...

INTRODUCTION: Replacement of the metacarpo-phalangeal joints (MCPJ) with silastic Swanson's implants can help decrease pain, stiffness and allow for improved function in rheumatoid arthritis (RA). There is a lack of patient reported outcome measure (PROM) studies assessing the efficacy of this procedure in RA. The aim of this study was to report any change in function, pain, stiffness and satisfaction following the Swanson MCPJ replacement using patient reported outcomes in a rheumatoid population...

BACKGROUND: Total hip arthroplasty (THA) is a common surgical treatment for several conditions of the hip. While the majority of patients obtain satisfactory results, many develop chronic post-arthroplasty hip pain that can be difficult to treat. OBJECTIVE: We evaluate the effectiveness of cooled (60°C) radiofrequency lesioning of the articular branches of the femoral nerve (ABFN) as a minimally invasive treatment for patients suffering from chronic post-arthroplasty hip pain...

OBJECTIVE: Scapular motion is essential for full, functional mobility of the arm. Many shoulder pathologies are associated with alterations of scapular kinematics which have been only little studied in total shoulder arthroplasties. The aim of this study was to compare the 3D scapula kinematics in two groups of patients with total shoulder anatomic (aTSA) or reverse (rTSA) arthoplasties to asymptomatic controls of comparable age during two arm elevation tasks (abduction and flexion) and two simulations of activity of daily living ("hair combing" and "back washing")...

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...

BACKGROUND: Postural stability is of great importance because imbalances and muscle weakness are significant risk factors for falls experienced by the elderly. Hip arthrosis, which causes pain and gait disorders that affect balance control, is common in the ageing population. AIM: The aim of this study was to assess postural stability in patients with unilateral hip arthrosis before total hip arthroplasty. METHODS: The study population consisted of 52 patients with hip arthrosis (study group) and 47 subjects with no history of clinical symptoms of hip pain...

Most of the destructive joint disease necessitating arthoplasty is the result of an insidious and protracted process that occurs over the course of many years. However, there are a variety of diseases that may result in a rapid progressive deterioration of a joint. We describe both the common and less common etiologies of rapidly destructive arthropathy that one should consider, with imaging examples, and present discriminative factors when present.
