Resumen del estudio

400 patients undergoing hemiarthroplasty for displaced intracapsular fractures were randomized to receive either cemented hemiarthroplasty (n=200) or uncemented hemiarthroplasty (n=200). Outcomes of interest included length of surgery, duration of anesthesia, incidence of blood transfusion, length of stay, incidence of adverse events, mortality, Parker and Palmer mobility score, and pain on a Visual Analog Scale (VAS). The mean duration of surgery and anesthesia were significantly shorter in the uncemented group, however, the length of ward and hospital stay were significantly shorter in the cemented group. All adverse events were comparable between the two groups except for the incidence of pneumonia which was higher in the uncemented group. The mean degree of residual pain was significantly lower in the cemented group at 8 weeks, 3, 6, 9 months, and 1, & 2 years. The cemented group also presented with a significant degree of mobility at 6 and 9 months, and 1 year. The results indicate that while the operative time was shorter in the uncemented group, the cemented group resulted in lower complication rates, lower pain, and better mobility, postoperatively.
