Anterior posterior inverted-'U' osteotomy for tibia vara: technique and early results.
BACKGROUND
Blount disease often requires operative treatment including osteotomy. This study evaluated the safety and outcome of the inverted-U osteotomy in Blount disease.


METHODS
We performed an anteroposterior inverted-U osteotomy without a jig or image intensifier in the treatment of a series of 31 children with the intention of achieving anterior-posterior stability at the osteotomy site without risk of major neurological and vascular injuries.


RESULTS
We found no vascular or common peroneal nerve injury. There was stability at the osteotomy site without the need for internal fixation. Thirty knees in 20 patients had good outcome, while 17 knees (11 patients) had fair outcome.


CONCLUSIONS
Our results suggest that this technique is safe, effective and gives satisfactory outcome in the operative correction of Blount's disease.
