[Percutaneous rotational osteoclasis in management of congenital radio-ulnar synostosis].
OBJECTIVE
Congenital radio-ulnar synostosis blocks the wrist in a position of more or less pronounced pronation. The degree of pronation and possible bilateral involvement can compromise upper limb function. We propose percutaneous osteoclasis of the antebrachial skeleton to remedy this situation


METHODS
We performed 12 percutaneous rotation osteoclasis procedures. The objective was to weaken the metaphysodiaphyseal cortical periosteum of one or both of the forearm bones by intermittent perforations. This enabled derotation of the wrist which was maintained for six to eight weeks in a brachiopalmar cast.


RESULTS
Mean correction of pronation was 51 degrees. There were no cases of vascular or nervous complications and healing was uneventful. The esthetic outcome was very satisfactory.


CONCLUSIONS
Surgery is not indicated for all cases of synostosis. We retain for surgery patients presenting pronation at 60 degrees or more. At this degree of pronation, function is greatly compromised in adolescence, particularly if there is a bilateral involvement. Compared with other techniques, percutaneous osteoclasis is a simple safe and reliable technique. Reoperation is not required to remove material. The procedure is easier in young children, preferably at the age of 3 to 7 years, before the development of a functional handicap.
