Metatarsal Parabola Problems
Failure of transfer of weight flow from Bosjen Moller (1979) oblique (low gear) axis to the transverse (high gear) axis will be interfered with by variations in the accepted normal metatarsal parabola.
Length of metatarsal increased or decreased weightbearing on metatarsal head symptoms (overload, capsulitis; bursitis; stress fracture; hyperkeratosis lesions)
Uncommon. Usually due to premature closure of epiphysis in metatarsal.
Adjacent metatarsal heads are overloaded; toe ‘floats’ – adjacent toes migrate into gap left by short toe.
