Varus instability of the hallux interphalangeal joint in a taekwondo athlete.
ABSTRACT The hallux interphalangeal joint is stable in the transverse plane and there have been only a few reports of varus instability of this joint. A case is described of varus subluxation of the hallux interphalangeal joint in a taekwondo athlete and the surgical outcome after reconstruction of the collateral ligament. Taekwondo athletes, who require fast powerful kicks, should be warned about this type of forefoot injury.

- "Sports-related epiphyseal injury in childhood has recently become more prevalent  . Children involved in sports that are performed without protective footwear often suffer from injuries to the big toe   ; however, epiphyseal fractures of the phalanges are uncommon. Although several studies have focussed extensively on the management of long-bone fracture  , there are scarce resources that address the presentation and management of epiphyseal fractures of foot phalanges in athletes   . "
ABSTRACT: The purpose of this study was to describe four exceptional cases of Salter-Harris type III and IV fractures of the proximal phalanx of the hallux in young high-level gymnasts. All gymnasts underwent the same mechanism of injury of hyperadduction, which indicates a role of the abductor hallucis muscle in the genesis and displacement of these fractures. An open reduction and internal fixation was performed to achieve an anatomical reduction and avoid chronic disability. At 1-year follow-up, all patients had an excellent American Orthopaedic Foot and Ankle Society (AOFAS) score (100 points), and there was no shortening or angulation of the first ray and no evidence of degenerative joint disease on X-ray. Moreover, all the gymnasts had returned to pre-injury levels of sporting activity. To our knowledge, there are no previous studies that address these types of injuries and how they are handled in gymnasts. Copyright © 2014 Elsevier Ltd. All rights reserved.Injury 10/2014; 45.

- "Shin et al. (2008) reported 7 cases of an open lateral collateral ligament injury of the 1st interphalangeal joint during Taekwondo in adolescents. Gong et al. (2007) also reported a case of varus instability of the hallux interphalangeal joint in a taekwondo athlete. The aim of this study was to evaluate any changes in the EHL tendon using ultrasound imaging in taekwando athletes compared to a control group. "
ABSTRACT: Extensor hallucis longus (EHL) tendon injuries can occur in taekwondo athletes when performing hyperplantarflexed barefoot kicking exercises. A state of full excursion of the extensor tendon is used to strike opponents in which the metatarsal bone and the proximal phalanx area is in contact with the opponent. The purpose of this study is to examine the incidence of extensor hallucis longus tendon injury in taekwondo athletes. Case-control study. 50 Athletes from the Korean taekwondo national team and a control group of 50 healthy subjects. History of sports participation, the American Orthopaedic Foot and Ankle Society (AOFAS) score and ultrasound imaging of the EHL. Difference in the AOFAS scores were noted with the control group at 92.95+/-9.18, and the experimental group score at 88.45+/-10.93 (p<0.01). Only one person (one tendon) from the control group demonstrated changes on sonography (2%), whilst 10 subjects from the taekwondo group displayed changes in 16 tendons (20%). EHL thickness of the experimental group (1.52+/-0.16 mm) was greater and the control group (1.46+/-0.11 mm) (p<0.01). Taekwondo athletes have a higher incidence of changes on sonographic imaging of the EHL compared to non-taekwando participating healthy subjects.Physical therapy in sport: official journal of the Association of Chartered Physiotherapists in Sports Medicine 09/2009; 10(3):101-4.

ABSTRACT: The authors use methods of stochastic approximation to convert iterative algorithms for maximizing the Kullback-Liebler information measure (1959) into sequential algorithms. Special attention is given to the case of incomplete data, and a variety of algorithms are presented to deal with situations of that kind. The authors consider the application of these algorithms to the identification of finite-impulse-response (FIR) systemsAcoustics, Speech, and Signal Processing, 1988.
