BACKGROUND Hallux abducto valgus and hallux limitus are two commonly encountered foot deformities causing altered structure and function of the first metatarsophalangeal joint and subsequent compensatory mechanisms. This study was undertaken to determine the relationships between these two deformities and transverse plane position of the foot, or angle of gait, and several radiographic angular ...

PURPOSE To report outcome of Scarf osteotomy with or without proximal phalangeal osteotomy for correction of severe hallux valgus deformity. METHODS Records of 48 women and 4 men aged 28 to 68 (mean, 52) years who underwent 57 Scarf osteotomies with or without proximal phalangeal osteotomy for severe hallux valgus by a single surgeon were reviewed. The patients had a hallux valgus angle (HVA)...

Methods of designing equipment to improve quality have been developed by Taguchi. A key feature of these methods is the development of loss function, which quantifies the financial cost (loss) resulting from deviations from target dimensions. Total knee arthroplasties can fail due to prosthetic component malalignment. A Taguchi loss function for varus/valgus alignment of the prosthesis and revi...

This study determines the biomechanical advantage and the optimal configuration of a high tibial osteotomy (HTO) and meniscus transplantation performed concurrently. Six cadaver knees were placed in a spatial frame, and an HTO was completed. Loading points between a mechanical 6 degrees of varus and 8 degrees ofvalgus were loaded to 800 N for medial meniscal intact, meniscectomized, and transpl...

OBJECTIVE To determine the ideal angle for making the distal femoral cut in total knee arthroplasty in a Brazilian population. METHODS Panoramic radiographs of the lower limbs bearing weight from 79 patients (57 women and 22 men) were studied, totaling 107 knees with an indication for total knee arthroplasty. The femoral anatomical axis, femoral mechanical axis and cervical-diaphyseal angle w...

Purpose: One of the most significant contributors to lower extremity degeneration alterations and its effects on balance and sports performance is dynamic knee valgus faulty movement pattern. Different exercise interventions have been conducted to improve dynamic knee valgus. The extensive research and meta-objective analysis aimed to assess how exercise interventions affected people with dynam...

BACKGROUND Although a change in tibial slope may occur during a medial opening wedge osteotomy, calculations have not been defined to address this problem. The authors investigated geometric factors important to correct axial alignment and tibial slope during osteotomy. PURPOSE To calculate, through 3-dimensional analysis of the proximal tibia, how the angle of the opening wedge along the ant...

BACKGROUND Foot problems are prevalent in older women and are thought to be associated with footwear. This study examined women's shoe wearing patterns over time and evaluated associations between footwear characteristics and foot pain and hallux valgus. METHODS Women aged 50-89 years (n = 2,627) completed a survey that included drawings of four toe-box shapes and four heel heights. For each ...

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...
