Abstract
A prospective randomized study was set up, comparing a compression hip screw with the Vandeputte (VDP) endoprosthesis treatment for fresh, unstable peritrochanteric fractures, according to the Evans-Jensen and AO systems. Ninety patients, ages > or = 70 years, 47 of whom were treated with a compression hip screw and 43 with a VDP endoprosthesis, were included. All patients were being followed for 3 months. No difference between the two groups was found for operating time, wound complications, and mortality rate, but there was a higher transfusion need in VDP treatment. Severe fracture redisplacement or total collapse of the fracture occurred in 11 (26%) compression hip screw patients, two of whom had revision surgery. Only one patient needed reintervention after VDP treatment. Functional capacity of preoperative independent patients at hospital discharge did not differ for the two groups. In conclusion, the compression hip screw seemed to be an appropriate implant for most of the peritrochanteric fractures, but for very old patients with advanced osteoporosis, with a complex, unstable peritrochanteric fracture, and who are eligible for early mobilization, primary cemented endoprosthesis might be the best treatment.
