“…Kenzora et al showed a better functional outcomes with less pain within the first 24 month after bipolar hemiarthroplasty compared to unipolar prostheses. One major disadvantage of hemiarthroplasty compared to total hip arthroplasty is potential erosion of the acetabular cartilage and long-term supero-medial protrusion of the femoral head into the acetabulum (30,31). This correlates with physical activity levels (5, 8, 21, 32), but the impact on functional health and well being in geriatric patients remains unclear.…”

Surgical treatment of femoral neck fractures is associated with a significant impact on quality of life. The aim of this study was to determine the long-term influence of displaced femoral neck fractures treated by bipolar hemiarthroplasty on the activities of daily living, quality of life and social dependency. We studied 487 geriatric patients treated in the years 1989 to 2003. At the beginning of follow-up in 2004, 166 patients were alive and evaluation was carried out on 145 patients (87.3%) at 91.3 (14 - 244) months postoperatively by a standardized questionnaire. All enrolled patients had been treated with cemented bipolar hemiarthroplasty for a displaced femoral neck fracture. Patients were evaluated concerning their average pre- and postoperative ability to walk, the need for assisting devices, type of residency and the SF-12® Score. Femoral neck fracture and hemiarthroplasty had a significant influence on all recorded aspects of quality of life. Even though almost two thirds of the patients needed assisting devices to walk after surgery, about two thirds returned to their original type of accommodation and the majority reached their original degree of mobility. Compared to a normal population no significant impact was observed on the quality of life measured by the SF-12® score. We consider bipolar hemiarthroplasty an effective treatment option for displaced femoral neck fractures in geriatric patients. Most patients returned to their original type of accommodation and level of mobility, even though the majority required a number of assisting devices to do so.

“…Studies with bipolar hemiarthroplasty indicate that acetabular wear is less of a problem than previously thought [8,31]. Several reports show, however, high rates of pain, migration, and the need for revision to THA in middle-and long-term followup [24,38].…”

Background Hemiarthroplasty has been shown superior to internal fixation for displaced femoral neck fractures (FNF) in the first 2 years. However, there are unanswered questions about the performance of hemiarthroplasty over the longer term compared with internal fixation. Questions/purposes We sought to compare hemiarthroplasty with internal fixation in terms of (1) outcomes scores for pain, hip function, and quality of life at a minimum of 5 years after surgery in a randomized trial. A secondary purpose was to compare (2) patient survival and (3) frequency of reoperation in the two groups. Methods A total of 222 consecutive patients older than 60 years, including those cognitively impaired, with FNF were randomized to either internal fixation with two parallel screws or bipolar hemiarthroplasty. At a minimum followup of 4.9 years (mean, 5.9 years; range, 4.9-7.2 years), 68 of the 70 surviving patients were examined by a study nurse and study physiotherapist blinded to initial treatment. Questionnaires on hip function (Harris hip score), quality of life (Eq5D), and activity of daily living function (Barthel ADL) were administered. The Barthel ADL index score was split into good function (score 95 or 100) and reduced function (score below 95).

“…To measure acetabular articular cartilage degeneration, we drew a line connecting the teardrops on the two sides of an AP radiograph, dropped a perpendicular line from the centre of the bipolar cup, and measured the vertical and horizontal distances from the teardrops. We calculated the square root of the difference between the value in the postoperative radiograph and the value in the final follow-up radiograph [4]. The rate of acetabular articular cartilage degeneration was calculated by dividing the migration of the bipolar cup by the length of the follow-up period.…”

“…In addition, the centre of rotation of the inner bearing is located more medially than the centre of rotation of the outer bearing to prevent dislocation. These implants have been widely used to treat femoral neck fracture, intertrochanteric fracture, and osteonecrosis of the femoral head [4][5][6][7]. However, although favourable outcomes have been reported in short-tointermediate-term follow-up studies [2,8], there is disagreement over the long-term outcomes [4,9,10].…”
