title: [Interlocking intramedullary nailing of the femur: is the advantage of early mobilization gained by risking a malposition?].
abstract: We report a follow-up of 57 consecutive femoral fractures treated by internal fixation with the AO Universal Interlocking Nall. All fractures (91% follow-up) had healed within a mean of 22 months (range 9-50) after operation. Full weight-bearing was possible after an average of 9 weeks (range 2-20). The only infection occurred after a secondary open lengthening osteotomy. In 5 cases a rotational malposition or length discrepancy had to be corrected shortly after initial surgery. Rotational malposition in excess of 10 degrees occurred in 26% of cases (mostly external rotation) and length discrepancy exceeding 1 cm in 13% (mostly shortening). The frequency of malposition is explained by the absence of rotational or length control during operation. We recommend that malposition be correlated without delay by reoperation.
