CANNULATED SCREWS FOR FIXATION OF FEMORAL-NECK FRACTURES - NO DIFFERENCE BETWEEN UPPSALA SCREWS AND RICHARDS SCREWS IN A RANDOMIZED PROSPECTIVE-STUDY OF 268 CASES

We compared 2 types of cannulated hip screws in a randomized prospecti ve study of 268 femoral neck fractures. Complications were defined as penetration of the screw into the joint, early redisplacement, nonunio n or segmental collapse. During the first year, complications were not ed in 31 of 130 patients treated with 3 Richards screws and in 34 of 1 38 patients treated with 2 Uppsala screws. Secondary arthroplasty was performed in 17 cases in the Richards group and in 16 cases in the Upp sala group. Clinical outcome did not differ between the groups.
