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...

High tibial osteotomy (HTO) has been widely used for clinical treatment of osteoarthritis of the medial compartment of the knee, and both opening-wedge and closing-wedge HTO are the most commonly used methods. However, it remains unclear which technique has better clinical and radiological outcomes in practice. To systematically evaluate this issue, we conducted a comprehensive meta-analysis by...

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 ...

Dysplasia of the hip is characterized by malpositioning of the proximal femur in a shallow acetabulum, providing deficient femoral head coverage. This abnormal relationship leads to altered biomechanics of the hip joint, as predicted by measurement of kinematic parameters such as increased load over reduced acetabular weight-bearing area, leading to increased joint contact stresses, which subse...

BACKGROUND AND AIMS The aim of this study is to evaluate the effect of proximal tibia osteotomy on hip biomechanics. METHODS This cohort study was conducted on 50 knees of 37 patients divided into two groups of unilateral and bilateral surgeries during 2015-2016. Patients underwent medial open-wedge osteotomy of proximal tibia. Axial alignment of lower limb radiography was carried out for the...

BACKGROUND Codman's paradox reveals a misunderstanding of geometry in orthopedic practice. Physicians often encounter situations that cannot be understood intuitively during orthopedic interventions such as corrective osteotomy. Occasionally, unexpected angular or rotational deformity occurs during surgery.This study aimed to draw the attention of orthopedic surgeons toward the concepts of orie...

To assess migration of the tibial component we used roentgen stereophotogrammetric analysis in 40 patients who had had a total knee arthroplasty after failure of a closing wedge osteotomy and compared them with 40 matched patients after primary total knee arthroplasty. We found no difference in migration over time or in the tendency for continuous migration between the two groups. There were no...

INTRODUCTION The end of medial opening oblique wedge high tibial osteotomy (HTO) points into a narrow area between the articular cartilage of the posterolateral proximal tibia and proximal tibiofibular joint (PTFJ) at the tibial site, which is an anatomical safe zone (ASZ) for osteotomy. We studied the ASZ and its relation to the fibular tip, including the level of posterior cruciate ligament (...

Degenerative changes of the first carpometacarpal joint commonly cause pain, weakness and adduction deformity. Many patients respond to conservative treatment, but in resistant cases an abduction wedge osteotomy of the base of the first metacarpal has been found to relieve symptoms with less complications than other operations. Twenty-one patients with 23 osteotomies have been reviewed, with a ...

We report the treatment in 17 patients of 27 angular deformities of the long bones by progressive opening-wedge osteotomy. The technique consists of percutaneous osteotomy and progressive angular correction using a modified Wagner distractor. Ten patients (20 bone segments) had adolescent bilateral idiopathic tibia vara with a mean angular deformity of 12 degrees varus (10 to 16). Seven other a...
