Congenital Bowing and Pseudarthrosis of the Lower Part of the Leg.
—Pseudarthrosis following fracture or osteoclasis during childhood in cases of congenital bowing of the lower part of the leg has been observed frequently, but its association with von Recklinghausen's neurofibromatosis has not been reported in the English literature. Barber1 reports 5 cases, in 4 of which there was definite bending of the lower part of the leg present at birth. In 1 case, fracture and operative intervention were avoided, with the result that no functional handicap now exists. In fact, some improvement in the degree of angulation took place with growth. Osteotomy, osteoclasis and fracture were each followed by pseudarthrosis in 3 cases. In 1 case, in which no history of bending could be obtained, pseudarthrosis followed fracture. In all of these cases typical lesions of von Recklinghausen's disease were present.
