Abstract:

BACKGROUND: Computer navigation plus intro-operative 3D imaging system is advanced device in the treatment of current orthopedic implants. Compared to two-dimensional, three-dimensional X-ray navigation is more minimally invasive, more accurate and safer.
OBJECTIVE: To compare the accuracy and safety of placing plates and screws by computer navigation plus intro-operative 3D imaging system and C-arm fluoroscopy assisted treating pelvic fracture.
METHODS: Surgical fixation of 58 cases of pelvic fracture was divided into two groups. The control group was treated with traditional C-arm, and test group was treated with computer navigation plus intro-operative 3D imaging system. Operative time, blood loss, blood transfusion, incision length, fluoroscopy time, reduction and functional recovery in cases were compared. 
RESULTS AND CONCLUSION: Test group was lower than control group in blood loss, blood transfusion, incision length and fluoroscopy time (P < 0.05). Two groups showed no significant difference in operating time or reduction satisfaction (P > 0.05). Except for 1 lost, 55 patients were followed up for 1-4 years (average 1.7 years). All fractures were healed, and no delayed union or nonunion. Functional recovery after 8 months showed no significant difference between two groups (P > 0.05). Computer navigation plus intro-operative 3D imaging system assisted pelvic fracture fixation is minimally invasive and precise, and safety to patients and medical staff. Moreover, it exhibits satisfactory reduction and fixation, as well as good long-term functional recovery.
