Abstract
Totally, 191 consecutive patients with femoral neck fractures during 1984 and 1985 had internal fixation with hook-pins and were prospectively investigated. Within 2 years, 62 patients had died and 47 had developed healing complications, 30 of whom had been treated with total hip replacement. Thus, 82 healed without complication. Forty-one of 47 patients without other handicaps affecting their walking ability considered their gait as good as it was preoperatively; 45 used no walking aids or a cane. Nine of 35 patients with a nonfracture-related disease affecting their walking ability managed to walk with or without acane; 13 considered their walking ability unaltered compared with their prefracture state. Three of 82 patients complained of pain on walking and 2 of pain at rest. All but 1 could flex their hip 90° or more. We believe that the function after internal fixation of cervical hip fracture with uncomplicated healing is superior to that achieved by primary hip replacement; primary replacement is recommended only in rheumatoid patients with displaced fractures.
