Objective(s): The effect of silica nanoparticles (SNPs) in sport shoes outsoles on the  parameters related to anterior cruciate ligament (ACL) Injury has not been investigated. The aim of this study was to investigate the effect of shoes outsole containing a composite of thermoplastic elastomer based on styrene-butadiene and silica nanoparticles (TPEN shoe) on Knee Valgus Angle (KVA) as a risk ...

Moderate to severe hallux valgus is conventionally treated by proximal metatarsal osteotomy. Several recent studies have shown that the indications for distal metatarsal osteotomy with a distal soft-tissue procedure could be extended to include moderate to severe hallux valgus. The purpose of this prospective randomised controlled trial was to compare the outcome of proximal and distal Chevron ...

We performed basal chevron metatarsal osteotomy on 32 feet (31 patients) for painful hallux valgus associated with an increased intermetatarsal 1/2 angle (> 12 degrees). Pedobarographic and radiological examinations were done preoperatively and at a minimum of six months postoperatively. The average hallux valgus angle was improved from 40.9 degrees to 19.2 degrees and the intermetatarsal 1/2 a...

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...

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)...

BACKGROUND The high frequency of hallux valgus deformities in females is well known and has been widely reported in the literature. This finding tends to obscure the importance and the characteristic details of hallux valgus deformities in males. The severity of the deformity, its onset at an earlier age, and its inheritability seem to be more frequent in males, but there are no reports in the ...

BACKGROUND Fibular shortening is one of the most common causes of ankle valgus deformity in children, and is frequently observed in patients with hereditary multiple exostoses (HME). It has been observed that the lateral distal tibial angle (LDTA) measured on the teleoradiograph differs from that on the ankle anteroposterior (AP) radiograph. The effect of the beam projection angle in the measur...

Background In total knee arthroplasty (TKA) for valgus knees, the decision to use a constrained implant is often made intraoperatively depending on the extent of soft tissue releases performed and residual soft tissue imbalance. The purpose of this study is to determine if preoperative radiographic criteria of valgus knees can predict the extent of soft tissue releases required and the level of...

BACKGROUND Distal osteotomy of the first metatarsal is indicated for the surgical treatment of mild-to-moderate hallux valgus deformity. The aim of this study was to evaluate the results of a subcapital distal osteotomy of the first metatarsal with use of a percutaneous technique. METHODS From 1996 to 2001, 118 consecutive percutaneous distal osteotomies of the first metatarsal were performed...

Objective: Hallux valgus is one of the most common foot deformities. It is considered that hallux valgus is associated with foot arch height, footwear, sex and so on. Toe grip strength (TGS) is important for developing foot posture because it attributes to foot arch height. The relationship between hallux valgus and TGS in children is unknown, although childhood is a key period for developing f...
