Trends of Surgical Treatment in Femoral Neck Fracture

We evaluated current trends of surgical treatment, such as internal fixation and hip arthroplasty, in femoral neck fracture. We assessed annual proportion of the each procedure in patients aged 50 years or more from 2006 to 2011, using the data of Health Insurance Review and Assessment Service (HIRA), which is a national claim registry. The proportion of hip arthroplasty increased while that of internal fixation decreased annually during the 5 years. The proportion of total hip arthroplasty increased in patients aged ≤65 years, and that of hemiarthroplasty increased in patients aged ≥65 years. The proportional increase of hip arthroplasty seemed to conform to the recent evidence regarding the outcomes of surgical treatments for the femoral neck fracture.
