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...

Correction of valgus deformity of the hindfoot using a medial approach for a triple fusion has only recently been described for patients with tight lateral soft tissues which would be compromised using the traditional lateral approach. We present a series of eight patients with fixed valgus deformity of the hindfoot who had correction by hindfoot fusion using this approach. In addition, we furt...

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 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 ...

BACKGROUND Hallux valgus deformity is a common chronic problem with a reported prevalence of 28.4% and its chief complaint is pain. Thus far, different surgical procedures with their proposed indications have been introduced. This study compared three current procedures, namely the chevron and scarf osteotomies and the McBride procedure. METHODS This retrospective cohort was conducted at the ...

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...

PURPOSE To report long-term results of total knee arthroplasty (TKA) for valgus knees. METHODS 34 women and 19 men aged 39 to 84 (mean, 74) years with valgus knees underwent primary TKA by a senior surgeon. Of the 78 knees, 43, 29, and 6 had type-I, type-II, and type-III valgus deformities, respectively. A preliminary lateral soft-tissue release was performed, and the tibia and femur were pre...

Blount's disease is an uncommon disorder of postero-medial proximal tibial physis. Blount described infantile and adolescent types. This study aims to describe using femur, tibia and fibula osteotomies to treat infantile Blount's disease. From May 1992 to May 2005, 7 patients of Blount's disease (3 males, 4 females) were included, whose age was range from 17 to 62 months. Femorotibial angle (FT...
