Non-uniform displacement within the Achilles tendon during passive ankle joint motion.

Purpose: An initial step in the understanding of Achilles tendon dynamics is to investigate the effects of passive motion, thereby minimising muscle activation and reducing internal joint forces. Internal tendon dynamics during passive ankle joint motion have direct implications for clinical rehabilitation protocols after Achilles tendon surgery. The aim of this study was to test the hypothesis that tendon tissue displacement is different in different layers of the Achilles tendon during controlled passive ankle joint movements.

Surgical treatment of hallux valgus and forefoot deformities in Sweden: a population-based study.

Background: Although surgical correction for hallux valgus and other toe deformities is one of the most common procedures in foot surgery, its incidence in the general population is not well-known.

Materials And Methods: The study population comprised patients living in Sweden of a varied age group and both sexes who underwent forefoot surgery. We identified all inpatient cases from 1997 to 2000 and all ambulatory cases in 2000 registered in the National Swedish Patient Register (NSPR).
