Bipolar hemiarthroplasty for femoral neck fracture in elderly: post-operative results and complications

Aim: In this study, we aimed to evaluate preliminary results and determine the rate of complications of bipolar hemiarthroplasty in patients aged 65 and older. Material and Methods: Patients aged 65 years and older with femoral neck fractures who underwent surgery at 7A Military Hospital from September 2013 to September 2018 were included into this study. The research is a descriptive and prospective study. Results: A total of 60 patients were studied. Aside from 1 deceased, 59 cases with 59 joints were replaced and followed up for an average of 15.3 months. Age and gender were not associated with the outcome of treatment. Implants included Zimmer 29, Serf 13, Stryker 9, and Depuy 9. There were 28 joints using cement and 32 joints cementless. The position of the stem was neutral in 54 cases, valgus in two instances, and varus in 4 cases. There were no loosen stem case. The cement technique was used in 17 cases (68%) type A and 8 cases (32%) Type B, according to Barrack classification. Clinical results according to Harris were as follows: 31 cases were very good, 12 cases were good, 5 cases were mean, and 11 cases were poor, equivalent to other authors. There were 6 cases of short limbs that reduced patient satisfaction. One case of incision infection was cleaned twice and stabilized after four weeks. One case of acetabulum worn after 32 months, but there were no clinical signs; one case dead from a stroke four weeks after the surgery without association with the operation. Discussion: Poor results are often caused by a combination of medical problems or aging. Early surgery provided better results than late surgery. There was no damage to blood vessels, nerves, fractures, or death during surgery. The bipolar hemiarthroplasty in the elderly group with very good and good rates accounted for a high proportion (72.88%). Early surgery was better (90%) compared to late surgery (69.38%). There were a few complications due to surgery.
