Brachymetatarsia
Brachymetatarsia or hypoplastic metatarsal is a condition in which there is one or more abnormally short metatarsals.[1] This condition may result due to a congenital defect or it may be an acquired condition.[1] It most frequently involves the fourth metatarsal. If it involves the first metatarsal, the condition is known as Morton's syndrome.[1] Treatment is via a number of differing surgical procedures.[1]
Differential diagnosis
Congenital causes include: Aarskog syndrome and Apert syndrome among many other well acquired causes includes trauma.[1]
Epidemiology
Brachymetatarsia is found to occur more frequently in women than men.[1]
Treatment
Depending on the severity of your condition you can treat the discomfort by wearing wide shoes and using something to cushion the toe. Another option is surgery to lengthen the bone.
