Abstract:
BACKGROUND:Bone nonunion may occur after limb trauma fracture. Internal fixation of implant is a common mode of repair, but fixation of different implants has different effects. OBJECTIVE:To explore the application value of different implant fixation in limb trauma of nonunion after femoral shaft fracture. METHODS:A retrospective analysis was performed on 72 cases of nonunion after femoral shaft fractures in Bozhou People’s Hospital from November 2012 to November 2013. They were divided into the observation group (36 cases) and control group (36 cases) according to the way of treatment, which were given interlocking intramedul ary nail and dynamic compression plate fixation. Length of incision, intraoperative blood transfusion volume, postoperative drainage volume, operation time, fracture healing time and functional recovery of knee joint were observed and compared between the two groups. RESULTS AND CONCLUSION:There was no statistical significance in operation time and length of the incision between the two groups (both P>0.05). Intraoperative amount of blood transfusion and postoperative drainage were significantly higher in the control group than in the observation group;the fracture healing time was significantly longer in the control group than in the observation group;infection rate in final fol ow-up was significantly higher in the control group than in the observation group (al P<0.05). No significant differences in preoperative knee joint International Knee Documentation Committee knee evaluation form and Lysholm score were found between the two groups (al P>0.05), but above two scores were significantly higher in the observation group than in the control group in final fol ow-up (al P<0.05). These findings suggest that compared with the dynamic compression plate, interlocking intramedul ary nail in treatment of bone nonunion after femoral shaft fracture can obtain good effect, firm fixation, low infection rate, and is more in line with the physiological and biomechanical requirements.
