PURPOSE: To determine the expression and distribution of bone morphogenetic protein (BMP)-7 and related molecules during peripheral nerve regeneration and to assess whether administration of parathyroid hormone (PTH) drug (1-34) potentiates the intrinsic upregulation of BMP-7/Smad signaling. METHODS: The rat sciatic nerves were crushed with an aneurysm clip resulting in axonal degeneration. In the normal nerve, and at 1, 2, 4, and 8 weeks after injury, BMP-7, BMP receptors, p-Smad 1/5/8, and Noggin, the endogenous BMP antagonist, were evaluated...

Current guidelines on the management of hip and knee osteoarthritis (OA) do not compare safety of treatment modalities. We therefore systematically reviewed 20 studies investigating mortality and serious complications of both medical and surgical treatments for hip and knee OA using PubMed, Scopus, Web of Knowledge and Google Scholar. Mortality was the highest for naproxen (hazard ratio (HR) = 3 (1.9, 4.6)) and lowest for total hip replacement (relative risk (RR) = 0.7 (0.7, 0.7)). Highest gastrointestinal complications were reported for diclofenac (odds ratio (OR) = 4...

Polyethylene (PE) remains the gold standard for the articulating surface in hip and knee arthroplasty. To increase arthroplasty longevity and improve wear resistance, newer versions of PE have been designed with resultantly different wear properties. Highly cross-linked polyethylene (HXLPE) is used in total hip arthroplasty with excellent outcomes; however, its use in total knee arthroplasty (TKA) remains conflicting. This review summarizes biomechanical and wear properties, clinical outcomes, and cost of polyethylene inserts in TKA...

PURPOSE: Cup setting with only an alignment guide has been reported to be inaccurate in the lateral decubitus position in total hip arthroplasty (THA). We assessed the accuracy of cup positioning using only the alignment guide technique via a modified Watson Jones approach in the lateral decubitus position. METHODS: Two hundred hips of 189 patients underwent THA from October 2014 to September 2016 via a modified Watson Jones approach. In the final sample, 181 hips of 171 patients (35 males, 136 females) were included in this investigation...

PURPOSE: Modern hip stem design includes a prosthesis that has a predictable outcome in all total hip arthroplasty (THA) patients, regardless of approach, surgeon or patient characteristics. Introduction without a learning curve and, in cases of problems, the possibility for a simple revision are other prerequisites. The purpose of this study is to evaluate whether the Accolade TMZF stem (Stryker Orthopedics, Mahwah, New Jersey, USA) is suitable to fulfil these demands. We report our mid-term survival of the Accolade TMZF hip stem in all patients from the first implantation at our institute...

PURPOSE: To evaluate a newly developed system for dynamic analysis of gait kinematics and muscle activity. METHODS: We recruited 10 healthy men into this study. Analyses of three-dimensional motion and wireless surface electromyogram (EMG) were integrated to achieve synchronous measurement. The participants walked continuously for 10 min under two conditions: comfortable and quick pace. Outcome measures were joint angles of the lower limbs determined from reflective markers and myoelectric activity of trunk and lower limbs determined from EMG sensors, comparing comfortable and quick gait pace...

PURPOSE: Allograft infection remains the greatest challenge in orthopaedic reconstructive surgery especially methicillin-resistant Staphylococcus aureus (MRSA). This risk can be minimized with the use of antibiotic laden allograft (ALA) via iontophoresis. Ceftaroline fosamil (CF) is an advanced-generation cephalosporin, an alternative treatment for MRSA infections. Its antibacterial activity and safety profile are better than vancomycin. CF iontophoresed bone has not been used before...

Slow recovery after hip fracture has been associated with negative consequences. Thus, there is medical need to improve healing and functional recovery after intertrochanteric fracture. The aim of this study was to measure whether short-term teriparatide would improve healing in intertrochanteric fractures after internal fixation as measured by (1) clinical scores, (2) radiographic fracture healing, and (3) complication rates. We retrospectively reviewed 96 patients (average age, 82 years) who underwent closed reduction and internal fixation with proximal femoral nail (PFN) for unstable intertrochanteric fractures between 2014 and 2016...

This study compared the treatment of total contact casting (TCC) with traditional dressing treatment (TD) in the management of neuropathic diabetic plantar ulcers. Thirty-one patients with plantar ulcers without any gross infection, osteomyelitis or gangrene were randomly assigned to the TCC group (n = 15) or TD group (n = 16). In the experimental group, TCC was applied on the initial visit and subjects were instructed to limit ambulation to one-third of their usual activity. Subjects in the control group (TD) were prescribed dressing changes and were advised against bearing weight on the involved extremity...

PURPOSE: Medial opening-wedge high tibial osteotomy (OWHTO) induces a lower patellar position, and the subsequent degree of patellar movement may not be predicted preoperatively. The purpose of this study was to clarify the relationship between preoperative and postoperative patellar height based on the correction angle of OWHTO and to create a formula to predict the appearance of patella baja following OWHTO. MATERIALS AND METHODS: Seventy-five knees with varus knee osteoarthritis treated with OWHTO were included in this study...

The majority of hip fractures in elderly patients are managed surgically with superior outcomes. However, for patients who refuse surgery or are deemed medically unfit, traction used to be the mainstay of nonsurgical treatment, which is associated with prolonged hospitalization and inpatient complications from immobility. This study, therefore, aims to evaluate the outcomes of an early wheelchair mobilization protocol as an alternative nonsurgical treatment option. This is a retrospective study of 87 elderly patients who were managed nonsurgically for their hip fractures over a 1-year period...
