Cervical hip fractures: osteosynthesis with hook-pins superior to AO-screws .
A randomised study in all cervical hip fractures Osteosynthesis with Hansson hook-pins versus AO-screws in 199 consecutive patients followed for two years
Injury. 2006 Aug;37(8):768-77. Epub 2006 Feb 14199 patients with cervical hip fractures were randomized to receive operation with two Hansson hook-pins or three AO titanium screws. According to radiographs taken after surgery, the hook-pin method resulted in significantly better implant positioning and less drill penetration of the femoral head than the AO screw method. Follow up during 2 years indicated that there was no difference between the two surgical techniques for mean time of stay in hospital, walking capacity, mortality rate, percent of patients requiring further operation, and reasons for reoperation.
