[Early and late results of 200 DHS osteosyntheses in the reconstruction of pertrochanteric femoral fractures].

We have treated more than 600 cases of trochanteric fractures by internal fixation with the dynamic hip screw. Between 1986 and 1988 we treated exactly 200 patients in this way, who were subsequently observed over follow-up times averaging 24 months. In 1% of this group we performed early revision osteosynthesis because of incorrect positioning of the lag screw; deep infections occurred in 2.5%; and in 6% revision interventions were necessary because of local hematomas. Late complications were necrosis of the femoral head (1%) and pseudarthrosis after head necrosis (0.5%). No reinterventions were necessary because of implant failure.
