Abstract
Introduction We present our earliest series of computer assisted minimally invasive fixation of intertrochanteric hip fractures using the dynamic hip screw.
Methods The first five cases of computer assisted minimally invasive dynamic hip screw fixation of intertro-chanteric femur fracture are presented. We used the Medivision Computer Navigation system. Our operative techniques, pitfalls and tricks are presented. All were performed in the standard lateral approach to the femur on a traction table. The minimally invasive cases had a incision length of 5 cm compared with an average length of 13.9 cm for the conventional procedure.
Results Technical difficulties in screw placement exists and screw head positions tends to be superior. There was one case of implant cutout. The others recovered uneventfully. Fluoroscopy time is halved, sparing the surgeon from excessive radiation. Operative time is prolonged by about 20 minutes. Patient satisfaction has been very good.
Conclusions Our procedure is safe and predictable. Patient satisfaction is high. The small wound allows for less pain and tissue dissection enabling faster and more effective rehabilitation. The instrumentation is based on the existing DHS system and there is no need to change inventory. The option of day surgery and same day discharges for hip fracture patients using this technique is tantalising.
