Abstract
Aims: The purpose of this prospective study is to evaluate the outcome of 15 subtrochanteric femoral fractures treated by MIPO condylar screw (DCS) in 8 cases. Methods: The fractures were classified according to Seinsheimer (10 type IV and 5 type V). In order to limit the amount of both medial and lateral dissection, the plates were carefully inserted through isolated proximal incision only, behind the vastus lateralis; while the CBP was initially inserted with the blade pointing towards the surgeon, the MIPO technique was simplified by the technique, using a condylar blade plate (CBP) in 7 cases or a dynamic use of the two-part and two-plane alignment achieved by DCS. Results: All fractures healed, with a mean time of 12 weeks (range 8–16 weeks). There were no infections or implant failure. At follow-up, there were 3 varus deformities above 5°, 2 leg length discrepancies over 15 mm and 1 malrotation of 20°. The functional outcome (according to the Neer scale) was excellent in 10 cases and satisfactory in 5 cases. Conclusions: This demanding technique has the advantages of a faster rate of union, with no need for bone grafting. Care should be taken to ensure adequate axial and rotational alignment.
