Osteotomy to improve selective Objective To investigate the articular surface of the metatarsal head metatarsophalangeal joint flexion direction of the second toe transplantation and recycling method of the thumb and fingers . Method 1: adult stem bone specimens 30 , measured on the the phalanges head articular surface morphology ; 2: 20 cases of adult foot specimens , the dorsal artery of the first metatarsal detailed anatomy ; 3 : Clinical six cases carrying the second toe metatarsophalangeal joint transplantation and recycling practical applications and long-term follow-up study of cases of thumb and finger . Results : adult stem bone measurement results : metatarsophalangeal joint collateral ligament attachment to the center of rotation , increasing as large by the back of the to plantar bottom of rotation radius of 3.0 ± 1.06mm, selective osteotomy bone articular surface . 2: the first dorsal metatarsal artery typing in line with the the GU sub- type , and at a distance of 5.0mm at the metatarsophalangeal joint surface into the metatarsal . The 3:6 clinical cases recycling metacarpophalangeal joint extension to flexion passive range of maximum 85 ° , minimum 65 ° , average 75 ° , active range of maximum 80 °, minimum 45 ° , average 65 ° , X - ray examination , bone healing , joint retirement behavior change performance . Osteotomy to improve the metatarsophalangeal joint flexion direction conclusion metatarsal head articular surface selective second toe transplantation and recycling thumb finger anatomically feasible , is a good way to improve the thumb and finger reconstruction function .
