We reviewed the early clinical results of 19 pertrochanteric fractures treated with the Proximal Femoral Nail (PFN). The average age of the patients was 78.4 years. The mean follow-up period was 70 days. The fractures were grouped into 5 types according to the Jensen classification. There were no significant differences between the sliding of lag screws in stable and unstable fractures. Intra-operative and extra-operative complications were one fracture of the lateral cortex and two cases of excessive telescoping. It appears that the hip pin of the PFN method might at least prevent rotational instability of the femoral head.
