metatarsal shaft torsion

metatarsal shaft torsion

developmental metatarsal valgus torsion, i.e. lateral (3, 4, 5) metatarsals undergo a greater degree of valgus torsion than those of medial column (1, 2); thus metatarsal bases maintain midfoot arched configuration, yet their heads contact the ground surface during weight-bearing and the foot retains an arched construction in both sagittal and transverse planes
