BACKGROUND The hallux valgus interphalangeus (HVI) deformity is described as rare, but improved outcomes in hallux valgus (HV) surgery is associated with its surgical correction via an Akin osteotomy. The hypothesis of this study is that HVI is common and makes a significant contribution to the total valgus deformity of the hallux (TVDH). METHODS 285 pre-operative foot radiographs (193 with H...

BACKGROUND Routinely, we use a midline skin incision and lateral parapatellar approach of the knee to perform valgus knee TKA (total knee arthroplasty). It is generally very difficult to close the lateral capsular defect after valgus knee TKA, especially for severe valgus and flexion knee deformity. METHODS We describe a new surgical technique to close the lateral capsular defect with a deep ...

Total knee arthroplasty following valgus deformity is a challenging procedure due to the unique set of problems that must be addressed. The aim of this study is to determine, with a finite element analysis, the load distribution for an inclined valgus prosthetic balanced knee and to compare these results with those of a prosthetic balanced knee with an uninclined interline. Computational simula...

INTRODUCTION The aetiology of hallux valgus is almost certainly multifactoral. The biomechanics of the first ray is a common factor to most. There is very little literature examining the anatomy of the proximal metatarsal articular surface and its relationship to hallux valgus deformity. METHODS We examined 42 feet from 23 specimens in this anatomical dissection study. RESULTS This analysis...

551 Hallux abducto valgus is one of the most common deformities encountered in podiatric medical practice. Hallux abducto valgus, commonly referred to as a bunion, may have two components: a rigid or structural component and a dynamic or flexible one. One component usually predominates over the other. The dynamic or flexible component is reducible clinically or after lateral soft-tissue release...

BACKGROUND Knee valgus and varus morbidity is at the second top place in children lower limb deformity diseases. It may cause abnormal stress distribution. The magnitude and location of contact forces on tibia plateau during gait cycle have been indicated as markers for risk of osteoarthritis. So far, few studies reported the contact stress and force distribution on tibial plateau of valgus kne...

Many surgical procedures have been described in the literature for the correction of hallux valgus,6 but a special knowledge of the etiologic factors, pathomechanics, and patient factors is needed to achieve a permanent solution for this deformity. There are two categories of recurrence: operative factors and patient factors. The main cause of recurrence associated with operative factors is imp...
