Wedge orthotics are commonly prescribed for patients with hyperpronation and/or low back pain to improve lower limb alignment and to reduce pain. The purpose of this study was to examine the kinetic effects of medial and lateral wedge orthotics during walking and stair negotiation. Twenty-two healthy young adults participated in the study. Each participant wore no wedge (W0) as a baseline and l...

PURPOSE To evaluate the correlation of kyphosis and wedge angles with pain relief and functional outcome after percutaneous vertebroplasty (PV). METHODS 15 men and 19 women aged 41 to 85 (mean, 62) years who presented with osteoporotic wedge compression fractures of the dorsolumbar spine below T5 and had failed conservative treatment were included. Patients were assessed before and one year a...

Abstract We consider Prandtl’s boundary layer problem for incompressible laminar flow past a three dimensional yawed wedge. When the Reynolds number is large the solution of this problem has a parabolic boundary layer. We construct a direct numerical method for computing approximations to the solution of this problem using a compound piecewise-uniform mesh appropriately fitted to the parabolic ...

We have investigated the benefits of patient specific instrument guides, applied to osteotomies around the knee. Single, dual and triple planar osteotomies were performed on tibias or femurs in 14 subjects. In all patients, a detailed pre-operative plan was prepared based upon full leg standing radiographic and CT scan information. The planned level of the osteotomy and open wedge resection was...

BACKGROUND Patellar instability can cause significant disability in both pediatric and adult patients, and it is associated with several factors including genu valgum. In this study, we describe the role of a lateral opening wedge distal femoral osteotomy (DFO) combined with lateral retinacular release in addressing genu valgum with associated patellar instability. The rationale for this approa...

Background: posttraumatic cubitus varus is a common complication after elbow fractures. There are different types of osteotomy and fixation methods used in correction of cubitus varus. Each has its advantages and disadvantages. Patients and method: Ten cases of cubitus varus in young adult treated with lateral closing wedge osteotomy and fixation with posterior Y plate. Preoperative X-ray was t...

High tibial osteotomy (HTO) is a surgical procedure to re-align varus or valgus mal-alignment of the knee. Medial opening wedge HTO is a surgical treatment of choice for knee varus mal-alignment with many advantages over lateral closing wedge HTO. However, the opening of the medial wedge alters the plane of the lateral tibial plateau, especially when the correction angle is large, which may be ...

BACKGROUND Opening wedge osteotomy of the medial cuneiform has become an established intervention for correction of forefoot varus in relation to a flatfoot deformity. The purpose of this study was to use a newly described radiographic measurement to determine the effectiveness and durability of the medial column correction with a plantarflexion opening wedge osteotomy of the medial cuneiform w...

BACKGROUND Orthotic devices are used to help children progressively acquire a more physiologic walking pattern. METHODS To determine the effect of an orthotic device with an out-toeing wedge along with a physiologic shoe as treatment for in-toed gait, angle of gait was measured in 48 children aged 3 to 14 years with in-toed gait. The following comparisons were made: angle of gait in children ...
