Purpose: We wanted to investigate the radiographic and clinical results of internal fixation with cannulated screws in elderly patients with femoral neck fracture.
Materials and Methods : We reviewed the results of 47 cases of elderly patients with femoral neck fractures that were treated by osteosynthesis from May 2000 and March 2009 and these patients could be followed up for more than one year. There were 11 males and 36 females with a median age of 72 years (65~85 years). They were classified by the Garden stage. The number of stage I and II fractures was 34 and 16, respectively. The postoperative follow up period was 24 months (12~84 months). The union time, horizontal shortening and complications were investigated. Walking ability was evaluated by Koval’s scoring system and the quality of life was measured by the Korean EQ-5D.
Results: The average union time was 4.4 months. The complications were one case of nonunion, 6 cases of avascular necrosis and one case of subtrochanteric fracture. The average of the horizontal shortening was 6.815 mm (0~20 mm) in the fracture site. The walking ability was on average 1 step down and it was possible to walk independently using a walker for 69% of the patients. The Korean EQ-5D quality of life was reduced from 0.856 to 0.561 (P <0.01).
Conclusion: In elderly patients with femur neck fracture, the decreased abductor moment arm may reduce the quality of life and walking ability after cannulated screw fixation.
