Haemangiomas developing in the hand in relation to tendon and the tenosynovium (tendon sheath) are very rare. To our knowledge only three cases have been described arising in relation to the tenosynovium of the tendons of the hand, only one of which showed infiltration of the underlying tendon. We report the case of a 16-year-old right hand dominant student who presented to her family doctor wi...

INTRODUCTION "On-top" and "side-to-side" plasties are techniques used for treating thumb duplications in which one thumb is adequate proximally and the other thumb contains a better pulp and nail distally. The detailed functional results of these techniques have not been reported in the literature. We report on two cases. PRESENTATION OF CASES The first case had Wassel type VI duplication. Th...

OBJECTIVE We report a case in which an avulsion-amputation of the thumb proximal to the lunula was repaired by reattaching the amputated segment as a composite graft. The graft demonstrated complete survival with only a minimal sacrifice in length. METHODS A 23-year-old man presented 4 hours after an avulsion injury of the thumb with associated distal and proximal phalanx fractures. The amput...

BACKGROUND Sports-related open lateral collateral ligament injury of the interphalangeal joint of the great toe has not been previously described in the English literature. HYPOTHESIS This injury can occur in adolescents while performing barefooted high-kicking or fast-running exercises involving rapid, 180 degrees turns on a dry, rough, wooden floor in a Taekwondo gymnasium. Injury occurs wh...

Reports that describe abnormalities of the muscles and tendons of the leg and foot are important with regard to understanding the function of the lower limb and correlating these abnormalities with the clinical aspects. Variations in the insertion of the extensor hallucis longus muscle were studied in 60 adult human cadavers. Three different patterns of insertion were noticed. Pattern I (65%): ...

In this paper, the optimal position control of an underactuated robotic finger is presented. Two trajectories, one for proximal and other medial phalanx, are proposed in order to emulate finger’s flexion/extension movements. A Mandani fuzzy due lack a precise dynamical model system. obtain parameters, optimization strategy based on membership functions applied. Genetic algorithms (GA) commonly ...

Introduction The term clawed hallux refers to a specific deformity of the great toe. It is clinically defined as the extension of the first metatarsophalangeal joint (MTPJ) combined with flexion of the interphalangeal joint (IPJ). This imbalance is presumed to be a result of a functional “overpull” (a disproportionate load) of one or more of the three extrinsic muscles of the first ray: the per...

Flexor tendon pulley ruptures are the most common injury in rock climbers. Therapeutic standards usually include a prolonged use of taping applied as a replacement for the lost pulley in a circular fashion at the base of the proximal phalanx. Our biomechanical considerations, however, suggest a new taping method, the H-tape. The purpose of the study is to evaluate whether this new taping method...

This study was performed to investigate the anatomy and variations of the human extensor tendons of the fingers and their intertendinous connections. Ninetyfive upper limbs of adult cadavers were dissected. The variations in the extensor tendons of the fingers, both proximal and distal to the extensor retinaculum, and their mode of insertion were observed. Also, the intertendinous connections w...
