Use of a laser guide to reduce screening time for the dynamic hip screw.
A prospective, randomized study was used to evaluate a laser guide to aim the image intensifier during the treatment of 52 patients with intertrochanteric fractures of the proximal femur using a dynamic hip screw. The laser guide reduces the fluoroscopic screening time by 40 per cent (P < 0.05). We conclude that laser aiming of the image intensifier has a role in training radiographers, and reducing the dosage of irradiation in theatre procedures.
