両側に発生した先天性下腿彎曲症の1例 (いわゆる先天性脛骨偽関節)

抄録

So-called pseudarthrosis of the tibia is one of rare diseases. Only 26 cases were seen in our clinic during 50 years (1926-1976), and they were all uni-lateral cases.
The following case is reported because it demonstrates both congenital bowing of the bilateral legs.
A Case Report
A boy aged 14 months was admitted with remarkable bending of the bilatelal tibiae and skin pigmentation. These findings were recognized immediately after the birth.
Operation
Left; Extirpation of the thickened periosteum
Right; Extirpation of the thickened periosteum and by-pass bone graft (tibia of his father) Findings at the openation
Periosteum was remarkably thickened. This is found in all of our uni-lareral cases, to which might relate the etiology of congenital pseudarthroses of the tibia.
