Etiology
• Idiopathic ‐ early closure of epiphyseal plate, most common
• Associated with other conditions such as Albright’s Syndrome , Down’s Syndrome , parathyroid alterations

Physiologyy gy
• Brachymetatarsia interrupts normal weight distribution on mid and forefoot
• Adjacent rays loaded excessively – pain and plantar callosities develop
h d d f d f• Short toes tends to drift upward, causing footwear problems
• Hallux valgus may develop

ResultsResults
• During 2 years follow up union was achieved in all lengthened metatarsi.
• In the 1st metatarsi injection of bone marrow was necessary to expedite a delay in union in one side.
• Due to insufficient length, shortening of the 2nd and 3rsd toes was added. 3 sd oes as added
• There were no major complications.• At last follow up patient had a normal pain free• At last follow up, patient had a normal, pain free gait.
