Abstract:

 Objective To evaluate the clinical effect of minimally invasive fixation of posterior intercondylar process fracture in adults with posteriormedial mini incision. Methods From March 2010 to March 2016, 21 adult patients with posterior intercondylar process fracture were treated by minimally invasive fixation with posteriormedial mini incision. There were 15 males and 6 females, with an average age of 37.6 years（range from 23 to 62 years）. All cases were closed fracture. The average time between injury and operation was 3.5 days （range from 0.5 to 8 days）. The clinical effects were assessed with HSS knee scores, and the fracture healing was assessed with images. Results The 21 patients were followed up for average 21.5 months（range from 13 to 52 months）. Fracture healings were successfully achieved in all cases, with no complications of infection, nerve injury and implant failure. The mean operation time was 48 minutes（range from 40 to 65 minutes）. The mean blood loss was 56 ml（range from 30 to 100 ml）. According to HSS knee scores, there were excellent in 17 cases, good in 3 cases, fair in 1 case. The overall excellent and good rate was 95%. Conclusion The technique that minimally invasive fixation of posterior intercondylar process fracture in adults with posteriormedial mini incision can accomplish less injury, satisfactory exposure, less blood loss and shorter operation time. The rehabil-itation is fast and it is an ideal technique to treat posterior intercondylar process fracture in adults.
