FIXATION OF FEMORAL-NECK FRACTURE - A RANDOMIZED 2-YEAR FOLLOW-UP-STUDY OF HOOK PINS AND SLIDING SCREW PLATE IN 222 PATIENTS

We compared fixation with hook pins or sliding screw plate in a prospe ctive randomized study of 222 patients with a cervical hip fracture. R adiographic evidence of early redisplacement, nonunion, or late segmen tal collapse was found in 43 of 122 patients operated on with two hook pins and in 40 of 100 patients operated on with the sliding screw pla te. According to the actuarial method, the failure rate after 2 years; was 38% with hook pins and 46% with screw plates, which not is a signi ficant difference. Due to early redisplacement, reoperation with an en doprosthesis was performed within 0.5 (2) years in 11 (22) patients in the hook-pin group and in 4 (17) patients in the sliding-screw plate group.
