Hallux valgus deformity combined with dorsal dislocation of the second metatarsophalangeal joint is frequently observed in rheumatoid arthritis cases. However, hallux valgus deformity without lesser toe dislocation is also seen in rheumatoid cases. Dislocated second toe cause the loss of the lateral support on the hallux, suggesting the importance to confirm the state of lesser toe MTP joint wh...

BACKGROUND Plantar ulcers produced by diabetic foot disease are devastating and costly. Better understanding of the ulcer-producing process is important to improve detection of feet that are at risk and to improve intervention. We identified and quantified soft-tissue and osseous structural changes in the forefoot of diabetic patients with a prior plantar ulcer. METHODS Thirty-two individuals...

OBJECTIVES To determine the relationship between osteoarthritis in the plantar region of the first metatarsophalangeal joint of the foot and patient pain after hallux valgus surgery. MATERIAL AND METHODS A total of 28 patients undergoing hallux valgus surgery were examined. The patients were examined for pain in the plantar region of the metatarsophalangeal joint (sesamoid bones area), by loo...

The first metatarsophalangeal joint of the human foot may best be classified as an anatomically condyloid synovial juncture. This joint is primarily formed by the rounded head of the first metatarsal bone, in sequence with the shallow concavity of the base of the first proximal phalanx. Whilst there is no dorsal ligament supporting or stabilizing the first metatarsophalangeal joint, the structu...

Hallux Abductus Valgus (HAV) is a pathology that affects the first metatarsophalangeal joint, in which there medial displacement of metatarsal and lateral deviation hallux, causing joint dysfunction disability patient.

PURPOSE OF THE STUDY The aim of this retrospective study was to assess functional and radiographic results of the first metatarsophalangeal joint replacement with use of unconstrained, modular, three components, porous titanium and hydroxyapatite coated, press-fit METIS® prosthesis. According to author's knowledge, results of that type of prosthesis have never been published before. MATERIAL ...

A 35 year old man presented to our emergency department after a traffic injury. Radiographic evaluation showed plantar dislocation of the second metatarsophalangeal joint and dorsal dislocation at the second tarsometatarsal joint. Under general anesthesia, closed reduction of the metatarsophalangeal joint was performed, followed by percutaneous fixation with a Kirschner-wire, and immobilization...

Degenerative plantar plate failure is an under-recognized cause of lesser metatarsalgia. We performed magnetic resonance imaging (MRI) with a small receiver coil in 13 patients in whom plantar plate ruptures of the second or third metatarsophalangeal joint were clinically suspected. In eight patients, MRI showed focal hyperintensity in the plantar plate that was interpreted as a rupture of the ...

A retrospective study of 50 chevron osteotomies evaluated subjective and objective functional and cosmetic results, which were in keeping with other reported studies--i.e. satisfactory subjective cosmesis in 98%; excellent or good pain relief in 84%; and satisfactory objective cosmesis in 84%. The correction of the 1st intermetatarsal angle averaged 3.3 degrees, and that of the metatarsophalang...
