Unipolar Hemiarthroplasty for Displaced Fracture of Femoral Neck in the Elderly at Rayong Hospital.

Abstract

          Between 1994-1998, 32 cases of displaced fracture of femoral neck were treated with primary unipolar hemiarthroplasty (Moore type) on the basis of limited life expectancy and low demand of functional level. They were 20 women and 12 men. Neither immediate postop. complication e.g. death, pneumonia, nor bed sore was noted. The average age was 72.6 years (range 55-89 years) and the length of follow up was from 3 months to 4 years. Two cases were lost of  follow up and among those remained 2 cases of superficial infection and 1 case of dislocation was found without any cases of acetabular erosion. Twenty-four cases out of 30 cases could regain functional activity as that before surgery. In this study we found that these patients had relatively low body weight with average of 50.1 kg. (range 42-61.5 kg.). We suggested that Moore hemiarthroplasty had a place in the treatment of displaced fracture of femoral neck of the elderly especially in cost-benefit implication.
