Bateman bipolar hip arthroplasty for femoral neck fractures. A five-
to ten-year follow-up study. LaBelle-LW; Colwill-JC; Swanson-AB Blodgett Memorial Medical Center, Grand Rapids, MI 49506. Clin-Orthop. 1990 Feb(251): 20-5 Displaced femoral neck fractures in 128 patients were treated with cemented Bateman universal proximal femoral bipolar hemiarthroplasties. The follow-up period ranged from five to ten years. In the surviving 49 cases, the average follow-up period was seven years and five months. Seventy-nine percent of surviving patients had no or slight pain after their primary procedure. None of these patients developed acetabular protrusio. Ten percent of the survivors required late revision; 88% of the unrevised hips had no or slight pain. When compared with studies of noncemented Moore and Thompson fixed-head prostheses, the cemented Bateman bipolar prosthesis had decreased protrusio and less pain.
