Effect comparison between hyperextension traction elastic compression combined with percutaneous pedicle screw in the treatment of single level thoracolumbar fracture

ObjectiveTo compare the effects of hyperextension traction elastic compression combined with percutaneous pedicle screw with traditional posterior incision pedicle screw internal fixation in the treatment of single level thoracolumbar fracture.

MethodsThe clinical data of 46 patients with thoracolumbar fracture were retrospectively analyzed.According to different treatment methods, the patients were divided into the hyperextension traction elastic compression combined with percutaneous screw placement group(24 cases) and traditional incision group(22 cases).The anterior vertebral edge height change, Cobb angle change, incision length, intraoperative blood loss, operative time, postoperative hospital stay, preoperative and postoperative visual analogue scale(VAS) scores, postoperative Japanese Orthopaedic Association (JOA) score and Oswestry disability index(ODI) score were compared between two groups.

ResultsCompared with the traditional incision group, the incision length, operation time, intraoperative blood loss and postoperative hospital stay in the percutaneous screw placement group reduced (P < 0.05).The Cobb angle of sagittal kyphosis in two groups decreased after surgery (P < 0.05).The anterior margin height of injured vertebrae was significantly higher than that before surgery (P < 0.05).The VAS scores at 1 week and 6 months after surgery were significantly lower than those before surgery (P < 0.05).After 6 months of surgery, the VAS and ODI scores in the percutaneous screw placement group were lower than those in the traditional incision group (P < 0.05), and the postoperative JOA score in the percutaneous screw placement group was higher than those in the traditional incision group (P < 0.05).

ConclusionsHyperextension traction elastic compression combined with percutaneous pedicle screw internal fixation in the treatment of thoracolumbar fracture has definite clinical efficacy, which has the advantages of less trauma, less bleeding, quick postoperative functional recovery, etc., and can provide a stable and reliable treatment for thoracolumbar fracture patients.
