Abstract
OBJECTIVE: To introduce the experience of intelligent monitoring system assisted pelvic fracture closed reduction to treat complex pelvic fracture in a minimally invasive method. METHODS: A 30-year-old male patient with complex pelvic fracture caused by a falling injury was treated in December 2019. The pelvic fracture was diagnosed by X-ray film and CT three-dimensional reconstruction. The AO/Orthopaedic Trauma Association (AO/OTA) classification was 61-C3.3 type (H-shaped sacrum fracture with pubic symphysis separation). At 48 hours after injury, the vital signs were stable, and the operation was performed. The pelvic fracture was reduced with the help of pelvic reduction frame and skeletal traction, the intelligent monitoring system, and fixed with the channel screws. RESULTS: The intraoperative blood loss was 50 mL, the operation time was 180 minutes, and the fluoroscopy time was 45 seconds. The incision healed well after operation. The X-ray film of pelvis was taken on the next day after operation, and the fracture reduction was evaluated as anatomical reduction according to Matta standard; CT three-dimensional reconstruction showed that the fixation screws were all located in the cortex of bone, without penetrating the cortex of bone. CONCLUSION: The intelligent monitoring system assisted pelvic fracture closed reduction is reliable in the minimally invasive treatment of complex pelvic fractures, which can achieve good results and reduce intraoperative fluoroscopy.
