Pigmented villonodular synovitis (PVNS) as well as tenosynovial giant cell tumor (TGCT) are both diagnosed and described in two forms, namely a localized and diffuse type. They form a diverse group of proliferative lesions in articular synovium and tendon sheaths. The inconsistent terminology impedes communication between patients, orthopedic surgeons, radiologists and pathologists, leading to misunderstandings and delaying treatment. In this paper, we present three cases of PVNS/TGCT (involving the fourth toe extensor tendon sheath, hip joint after resurfacing and flexor hallucis longus tendon sheath) together with suggestions regarding the unification of the terminology as well as diagnosis and treatment...

BACKGROUND: Resurfacing of the glenohumeral joint for patients with glenohumeral arthritis has gained popularity since the first introduction. We report the mid-term results of the Global C.A.P. uncemented resurfacing shoulder prosthesis (DePuy Synthes). METHODS: From January 2007 to December 2009, 48 humeral cementless resurfacing prostheses in 46 patients were performed. All patients were diagnosed with primary glenohumeral osteoarthritis. Patients were contacted for review; the Constant Score, visual analog pain scale, Dutch Simple Shoulder Test, SF-12 scores and physical examination were assessed both preoperatively and yearly postoperatively...

BACKGROUND: The cross-sectional morphology of the prosthetic knee is crucial to understanding patellar motion and quadriceps strength after total knee arthroplasty. However, few comparative evaluations of the cross-sectional morphology of the femoral trochlea have been performed in the native knee and currently available femoral implants, and the relationship between the trochlear anatomy of prosthetic components and post-operative patellofemoral complications remains unclear. We aimed to investigate the differences in cross-sectional morphology of the femoral trochlea between native knees and prosthetic femoral components...

BACKGROUND: Recent studies indicate that females demonstrate an increased risk of experiencing adverse local tissue reactions, aseptic loosening, and revision after primary metal-on-metal hip resurfacing arthroplasty compared with males; the underlying biological mechanisms responsible for sex discrepancies in implant failure remain unclear. In addition to anatomical and biomechanical sex differences, there may be inherent immunological disparities that predispose females to more aggressive adaptive immune reactivity to implant debris, i...

The effect of previous conservative surgeries on the outcome of metal-on-metal hip resurfacing arthroplasty (HRA) has not been studied. This study compared postoperative clinical scores and survivorship results of hips with and without previous osteotomies in a population of patients who underwent HRA. A total of 1101 patients (1375 hips) with a mean age of 51.3 years at the time of surgery underwent HRA at a single center. Sixty-nine patients had undergone prior surgery on the operated hip including 14 osteotomies (1 pelvic, 6 femoral, and 7 combined pelvic and femoral osteotomies)...

Introduction Superior semicircular canal dehiscence syndrome was described by Minor et al in 1998. It is a troublesome syndrome that results in vertigo and oscillopsia induced by loud sounds or changes in the pressure of the external auditory canal or middle ear. Patients may present with autophony, hyperacusis, pulsatile tinnitus and hearing loss. When symptoms are mild, they are usually managed conservatively, but surgical intervention may be needed for patients with debilitating symptoms. Objective The aim of this manuscript is to review the different surgical techniques used to repair the superior semicircular canal dehiscence...

OBJECTIVE: The most commonly used dermal fillers are hyaluronic acids (HAs), and in general, are well tolerated with mild to moderate risk of adverse events. The most frequently reported side effects are injection site erythema and bruising. We present the first case of a patient who developed a severe granulomatous foreign body reaction to the HA filler, Belotero Balance. In our review of the literature, a granulomatous reaction has never before been reported as a side effect of this particular HA filler (1)...

Femoral bone fracture is one of the main causes for the failure of hip arthroplasties (HA). Being subjected to abrupt and high impact forces in daily activities may lead to complex loading configuration such as bending and sideway falls. The objective of this study is to predict the risk of femoral bone fractures in total hip arthroplasty (THA) and resurfacing hip arthroplasty (RHA). A computed tomography (CT) based on finite element analysis was conducted to demonstrate damage formation in a three dimensional model of HAs...

BACKGROUND: Surgery is used to treat persistent pain and dysfunction at the base of the thumb when conservative management, such as splinting, or medical management, such as oral analgesics, is no longer adequate in reducing disability and pain. This is an update of a Cochrane Review first published in 2005. OBJECTIVES: To assess the effects of different surgical techniques for trapeziometacarpal (thumb) osteoarthritis. SEARCH METHODS: We searched the following sources up to 08 August 2013: CENTRAL (The Cochrane Library 2013, Issue 8), MEDLINE (1950 to August 2013), EMBASE (1974 to August 2013), CINAHL (1982 to August 2013), Clinicaltrials...

AIMS: Our first aim was to determine whether there are significant changes in the level of metal ions in the blood at mid-term follow-up, in patients with an Articular Surface Replacement (ASR) arthroplasty. Secondly, we sought to identify risk factors for any increases. PATIENTS AND METHODS: The study involved 435 patients who underwent unilateral, metal-on-metal (MoM) hip resurfacing (HRA) or total hip arthroplasty (THA). These patients all had one measurement of the level of metal ions in the blood before seven years had passed post-operatively (early evaluation) and one after seven years had passed post-operatively (mid-term evaluation)...

Background The anterolateral thigh (ALT) flap remains a workhorse for soft tissue reconstruction. However, the traditional ALT flap is often too bulky for resurfacing shallow, distal extremity defects, prohibiting adequate function, or well-fitted orthotics. This study evaluates extremity reconstruction using ALT flaps elevated in the suprafascial or super-thin plane. Methods Retrospective review of ALT free flap reconstruction from October 2014 to July 2016 was performed. Suprafascial and super-thin flaps were those elevated just above the crural fascia and within the superficial scarpal plane, respectively...

BACKGROUND: Metal-on-metal hip resurfacing (MoMHR) has been proposed as an effective surgical treatment for young and active patients with symptomatic hip disease. Recently, good clinical and radiographic outcomes have been reported by the designer surgeons at a 15.3 years follow-up; however, results at long follow-up by non-designer surgeons are less satisfactory. The aim of the study was to investigate if MoMHR can produce satisfactory clinical and radiographic results and if survival rate can be high even if the procedure is performed by non-designer surgeons...

Metal-on-metal hip resurfacing has gained popularity as a feasible treatment option for young and active patients with hip osteoarthritis and high functional expectations. This procedure should only be performed by surgeons who have trained specifically in this technique. Preoperative planning is essential for hip resurfacing in order to execute a successful operation and preview any technical problems. The authors present a case of a man who underwent a resurfacing arthroplasty for osteoarthritis of the left hip that was complicated by mismatched implant components that were revised three days afterwards for severe pain and leg length discrepancy...

PURPOSE OF REVIEW: As the number of patients taking more than one medication concurrently continues to increase, predicting and preventing drug-drug interactions (DDIs) is now more important than ever. Administration of one drug can cause changes in the expression and activity of drug metabolizing enzymes (DMEs) and alter the efficacy or toxicity of other medications that are substrates for these enzymes, resulting in a DDI. In today's medical practice, potential DDIs are evaluated based on the current medications a patient is taking with little regard to drugs the patient has been exposed to in the past...
