Abstract
Objective To investigate application of two-dimensional navigation in internal fixation of hip fractures. Methods From May 2006 to October 2009, we used two-dimensional navigation technique to assist internal fixation in 28 patients with hip fractures. There were 13 cases of femoral neck fractures. They were 8 males and 5 females, with an average age of 54.5±7.3 years. By Garden classification, 3 of them were type Ⅱ, 8 type Ⅲ and 2 type Ⅳ. There were 15 cases of intertrochanteric fractures. They were 7 males and 8 females, with an average age of 74.5±9.6 years. By Evens-Jensen classification, 2 of them were type IB, 7 type DA, 4 type ⅡB and 2 type Ⅲ. Both groups were compared respectively with their control groups which did not use navigation technique to assist internal fixation in terms of operation time, intraoperative blood loss, fluoroscopy frequency, incision length, healing time, Harris hip score and postoperative complications. Results Postoperative X-ray films showed all the implants were inserted accurately. All the 28 patients obtained follow-up from 12 to 24 months (average, 18 months). For the group of femoral neck fractures, the fluoroscopy frequency (3.3±1.1 times) was significantly lower than that for its control group (9.1±3.1 times) (P 0.05). For the group of intertrochanteric fractures, intraoperative blood loss (100.1±7.9 mL) was significantly less, fluoroscopy frequency (4.3±1.0 times) significantly lower, incision length (4.8±0.7 cm) significantly shorter, and Harris hip score at the last follow-up (82.1±8.8) significantly higher than those for its control group (207.2±10.5 mL, 6.5±1.3 times, 5.6±1.6 cm and 76.3±9.4, respectively) (P 0.05). Conclusion Application of two-dimensional navigation in internal fixation of hip fractures can improve surgical efficiency by ensuring high fixation accuracy and reducing operative invasion and radiation exposure.
