We compared a new fixation system, the Targon Femoral Neck (TFN) hip screw, with the current standard treatment of cannulated screw fixation. This was a single-centre, participant-blinded, randomised controlled trial. Patients aged 65 years and over with either a displaced or undisplaced intracapsular fracture of the hip were eligible. The primary outcome was the risk of revision surgery within one year of fixation. A total of 174 participants were included in the trial. The absolute reduction in risk of revision was of 4.7% (95% CI 14.2 to 22.5) in favour of the TFN hip screw (chi-squared test, p = 0.741), which was less than the pre-specified level of minimum clinically important difference. There were no significant differences in any of the secondary outcome measures. We found no evidence of a clinical difference in the risk of revision surgery between the TFN hip screw and cannulated screw fixation for patients with an intracapsular fracture of the hip.
