A prospective investigation of the effects on the medial and lateral neurovascular structures of the rearfoot after percutaneous posterior calcaneal displacement osteotomy was performed using 20 below the knee fresh frozen cadaver specimens. This anatomic study aimed to examine the medial and lateral neurovascular structures to determine whether they were jeopardized during execution of the ost...

The orthopaedic surgeon who performs opening-wedge high tibial osteotomy (HTO) has to be aware of the behavior slope depending on variations in location hinge and inclination osteotomy. most important point is that changing both rotation axis cut affects slope. There a natural trend unintentionally increase when performing an HTO. However, increased been established as risk factor for primary r...

An opening-wedge osteotomy is well recognised for the management of limb deformity and requires an understanding of the principles of geometry. Translation at the osteotomy is needed when the osteotomy is performed away from the centre of rotation of angulation (CORA), but the amount of translation varies with the distance from the CORA. This translation enables proximal and distal axes on eith...

The use of standing radiographs to determine correction angles for high tibial osteotomy is not appropriate because the relative angle of the articular surfaces (condylar-plateau angle) in the weight-bearing knee changes after the osteotomy. This may give unpredictable results postoperatively. We found that the condylar-plateau angle in postoperative standing films is very similar to that seen ...

BACKGROUND High tibial osteotomy (HTO) is used to treat medial compartment osteoarthritis of the knee in active patients with varus alignment. In this study we review the clinical and radiographic outcomes associated with the Taylor Spatial Frame (Smith & Nephew), and its use in HTOs, and we include an illustrative case report. METHODS In 7 patients with medial compartment osteoarthritis of t...

PURPOSE To review outcomes of open wedge osteotomy of the proximal medial tibia for malunited tibial plateau fractures. METHODS Seven men (mean age, 36 years) underwent open wedge osteotomy of the proximal medial tibia for instability secondary to malunited tibial plateau fractures of Schatzker types IV (n=3), V (n=1), and VI (n=3). Five patients had been treated conservatively and 2 surgical...

background: this is a case series of 76 knees of 62 patients who underwent upper tibial valgus osteotomy for treatment of medial compartment osteoarthritis during a 20-year period and who were followed for a mean of 7.6 years.   methods: the patients were evaluated by validated outcome assessment systems of general health status short form (sf-36), the western ontario mcmaster osteoarthritis in...

BACKGROUND The authors report the long-term effect of acquired pseudoarthrosis of the fibula on ankle development in children during skeletal growth, and the results of a long-term follow-up of Langenskiold's supramalleolar synostosis to correct an ankle deformity induced by an acquired fibular segmental defect in children. METHODS Since 1980, 19 children with acquired pseudoarthrosis of the ...

Purpose: high tibial osteotomy (HTO) is a recommended treatment for medial compartment knee osteoarthritis. Newer cartilage regenerative procedures may add benefits to the result of HTO. In this prospective study we investigate safety and also results of HTO associated with bone marrow derived cells (BMDC) transplantation in relatively young and middle aged active individuals with early osteoar...
