Older people are more likely to experience pelvic fractures than younger people. Multi-slice spiral computed tomography (CT) uses three-dimensional (3D) reconstruction technology to generate 3D images that can clearly demonstrate the 3D space of fractures and detect fractures at a higher rate.
To investigate the clinical value of multi-slice spiral CT 3D reconstruction in the diagnosis of unstable pelvic fractures in the elderly as well as the effect of less invasive stabilization.
A total of 86 patients with unstable pelvic fractures treated between March 2016 and March 2019 underwent femoral supracondylar bone traction before surgery. Pelvic radiography and multi-row spiral CT were performed successively once the patient’s vital signs and hemodynamic indices were stable. Secondary processing of the original data was performed to obtain 3D reconstruction images and determine the vertical displacement of the pelvis. After basic or complete reduction, minimally invasive internal fixation using hollow lag screws was performed. The detection rates of fracture location and classification by X-ray and CT reconstruction were compared. Patients were divided into two groups according to the presence or absence of preoperative 3D reconstruction to compare postoperative reduction, wound healing time, fracture healing time, hospitalization time, visual analog scale (VAS) score, poor internal fixation, and functional recovery.
The diagnostic coincidence rates of X-rays for pubic symphysis, ilium wing, sacroiliac periarticular, and sacral fractures were lower than those of CT reconstruction. The coincidence rate of CT reconstruction in the clinical classification of pelvic fractures was 100%, whereas 11 cases were misdiagnosed by X-ray; the total coincidence rate was 87.21%. The total excellent and good rates of postoperative reduction were significantly higher in the study group than in the control group (P < 0.05). The wound healing, fracture healing, and hospitalization times were significantly shorter in the study group than in the control group (P < 0.05). The VAS scores decreased in both groups postoperatively and were lower in the study group than in the control group (P < 0.05). The total incidence of poor postoperative internal fixation was significantly lower in the study group than in the control group (P < 0.05). The overall rate of postoperative functional recovery was significantly higher in the study group than in the control group (P < 0.05).
Multi-slice spiral CT has high guiding significance for the diagnosis, classification, and treatment of unstable pelvic fractures in the elderly. Preoperative 3D reconstruction can effectively shorten the operation time and promote fracture healing, while minimally invasive internal fixation can effectively reduce pain and promote functional recovery of fracture sites, making it worthy of clinical application.
Core Tip: Multi-slice spiral computed tomography has high guiding significance for the diagnosis, classification, and treatment of unstable pelvic fractures in elderly individuals. Preoperative three-dimensional reconstruction can effectively shorten the operation time and promote fracture healing, and minimally invasive internal fixation can effectively reduce pain and promote functional recovery of fracture sites, making it worthy of clinical application.
