In 300 femoral neck fractures treated with hook-pin internal fixation, no perioperative mortality and no deep infection was seen. Eighty-four patients (28%) died within two years of the date of fracture. At two-year follow-up examination, 56 of 300 cases (19%) had developed radiographic healing complications, i.e., redisplacement, nonunion, or segmental femoral head collapse (26% of the survivors). Three of 85 undisplaced fractures (4%) developed segmental collapse (5% of the survivors) while among displaced fractures, radiographic evidence of mal-healing was found in 53 of 215 cases (25%; 35% of survivors) at two-year follow-up examination. In the total series, secondary hip arthroplasty was performed in 34 cases (11%). Atraumatic reduction and internal fixation are recommended as primary treatment in femoral neck fractures.
