Moiré topography in the care of foot deformities.

Podoscopic images and moiré images combined are useful for comparing the foot under weight-bearing and non-weight-bearing conditions. This makes it possible to evaluate the effect of weightbearing on the bone structures of the foot and is valuable in the treatment of foot deformities.

Tarsometatarsal amputation and tibialis anterior tendon transposition to cuneiform I.

Tarsometatarsal amputation often results in dropfoot followed by pressure points problems and making prosthetic fitting difficult. To avoid the dropfoot deformity and retain mobility of the ankle, the amputation was modified by transposing the tibialis anterior from metatarsal I to cuneiform I.

A new operation for hallux valgus.

A distal oblique osteotomy on the first metatarsal, with lateral displacement of the metatarsophalangeal joint and internal fixation with a compression screw, was performed. No splint or plaster was used. The operation is relatively simple and effective.
