The first metatarsal bone under loading conditions: a finite element analysis

K-H Kristen et al. Foot Ankle Clin. 2005 Mar.

Abstract

An individual-based, three-dimensional finite element model of the first metatarsal (MT I) bone was created with fine CT. The three-dimensional model of the bone was fixed proximally at the metatarsocuneiform joint and load was applied on the metatarsal head. Loading conditions were simulated, including muscular forces as described for a normal metatarsophalangeal (MTP) joint during three typical phases of gait as the combination of the load in the contact areas of the sesamoid bones and the base of the proximal phalanx. The resultant strain and stress distributions within the loaded MT I were calculated and visualized with the MTP in different positions.
