60 patients between the ages of 55-95 with low-energy intertrochanteric unstable proximal femoral fractures were randomized to receive a dynamic hip screw or intramedullary nail. The primary outcome of interest was the performance of the timed up and go (TUG) test, measured at 2, 4 and 12 weeks. Patients completed the abbreviated mental test score (AMTS) to determine the level of cognitive impairment. The results of this study found that patients with AMTS scores < 8 were less likely to perform the TUG test and attended follow ups at a lower rate compared to patients with AMTS => 8.
