Idiopathic avascular necrosis of first metatarsophalangeal head in child is unique condition not described in literature in past exlude one case. It seems to be part of avascular bone necrosis syndromes, like Freiberg disease, Sever disease etc. and the same principles of treatment are appropriate in AVN of 1st MTT head. We describe the case of bilateral AVN of 1st MTT head treated conservative...

The ostrich is highly specialized in terrestrial locomotion and is the only extant bird that is both didactyl and exhibits a permanently elevated metatarsophalangeal joint. This extreme degree of digitigrady provides an excellent opportunity for the study of phalangeal adaptation towards fast, sustained bipedal locomotion. Data were gathered in a semi-natural setting with hand-raised, cooperati...

The two main movements occurring between the forefoot and rearfoot segment of a human foot are flexion at the metatarsophalangeal joints and torsion in the midfoot. The location of the torsion axis within the foot is currently unknown. The purpose of this study was to develop a method based on Cardan angles and the finite helical axis approach to calculate the torsion axis without the effect of...

Foot pathologies can negatively influence foot function, consequently impairing gait during daily activity, and severely impacting an individual's quality of life. These pathologies are often painful and correspond with high or abnormal plantar pressure, which can result in asymmetry in the pressure distribution between the two feet. There is currently no general consensus on the presence of as...

Radiological progression of rheumatoid arthritis (RA) was evaluated retrospectively in eight patients with amyloidosis secondary to classical or definite RA and successful renal transplantation. Wrist joints, metacarpophalangeal, proximal interphalangeal, and metatarsophalangeal joints were graded on a scale from 0 to 5. The annual progression rate was calculated separately for the time before ...

Extraskeletal chondroma is a rare benign tumor with symptoms that could mimic other common musculoskeletal pathological entities. We present a rare case of an extraskeletal para-articular chondroma of the first metatarsophalangeal joint which was initially misinterpreted as joint synovitis, based on magnetic resonance imaging findings. Histology revealed benign chondroma of the foot, which was ...
