The data from 35 consecutive patients with hallux valgus undergoing triplane arthrodesis at the first tarsal metatarsal joint were studied to determine the amount of first metatarsal frontal plane rotation (supination) needed to anatomically align the first metatarsal phalangeal joint on an anterior posterior radiograph without soft tissue balancing at the first metatarsal phalangeal joint. Rad...

HYPOTHESIS Does metatarsal pronation exist and, if so, what is its impact? INTRODUCTION Hallux valgus is a deformity associating angulation and a rotational component. The present study sought to investigate the nature and origin of the coronal plane displacement. MATERIALS AND METHODS A prospective single-center radiological and anatomic study was conducted on 100 feet operated on for hall...

Introduction Metatarsal fractures, especially of the 5th metatarsal are an increasingly common orthopedic problem among athletes [1]. Sports with a substantial amount of sprint and cutting movements appear to be at greater risk for both stress and acute fractures of the fifth metatarsal. One mechanism of injury is proposed to be the cumulative effect of the many bending moments applied to the f...

the silver carp (hypophthalmicthys molitrix) compnses about 50% to 85% of the composition offish species in the polyculture system of warm water species in iran. however, the difficulty in preparation of this species and the presence of pin bones are among the main reasons to restrict the demand of this species in the domestic markets, particularly in non­ coastal provinces. the objective of th...

Most orthopaedic surgeons must be familiar with the type of foot shown in Figure 1. There are hard, painful callosities under the first and fifth metatarsal heads, but there is no deformity of the toes. The patient with this condition has usually attended the chiropodist but has gained only transient relief after the callosities have been pared away. The wearing of metatarsal insoles or metatar...

Bones elongate through endochondral ossification in cartilaginous growth plates located at ends of primary long bones. Linear growth ensues from a cascade of biochemical signals initiated by actions of systemic and local regulators on growth plate chondrocytes. Although cellular processes are well defined, there is a fundamental gap in understanding how growth regulators are physically transpor...

PURPOSE The "bean-shaped foot" exhibits forefoot adduction and midfoot supination, which interfere with function because of poor foot placement. The purpose of the study is a retrospective evaluation of patients who underwent a combined double tarsal wedge osteotomy and transcuneiform osteotomy to correct such a deformity. METHODS Twenty-seven children with 35 idiopathic clubfeet were treated...

BACKGROUND Custom molded insoles with metatarsal supports are used to redistribute excessive loading under the metatarsal heads in patients with metatarsalgia. However, these pressure reductions are usually insufficient for the rheumatoid foot with painful deformed metatarsal heads. We developed an effective insole made by sequential foam padding under successive walking impression. METHODS S...
