Abstract

Abstract:

BACKGROUND: The surgical treatment of thoracolumbar vertebral compression fractures can avoid long-term bedridden patients, and recover thoracolumbar sagittal plane. However, the traditional method of muscle dissection at median spine on both sides along the spinous process revealed big trauma and much wound bleeding. Muscle denervation and chronic back pain easily occur after operation. The traditional method is four screws of cross-wound vertebra, which is easy to collapse and loss with the height of the injured vertebra for a long time.

OBJECTIVE: To compare rehabilitation in patients with thoracolumbar fracture after surgical treatment, and to compare the clinical effects of paraspinal approach combined with internal fixation through pedicle of fractured vertebra and traditional AF screw-rod system in the treatment of thoracolumbar fracture.

METHODS: A total of 96 cases of thoracolumbar fracture were selected from the Department of Orthopedics, Tianjin Third Central Hospital from July 2009 to June 2014. These patients were randomly divided into two groups. Totally 42 cases were treated by paraspinal approach combined with internal fixation through pedicle of fractured vertebra, while 54 cases received the treatment of traditional AF screw-rod system. Operation time, intraoperative blood loss, postoperative drainage volume, postoperative internal fixation and self-conscious symptom improvement were recorded and evaluated in both groups.

RESULTS AND CONCLUSION: (1) Follow-up time: The patients in the paraspinal approach combined with internal fixation through pedicle of fractured vertebra group were followed up for 8-12 months, averagely 13.4 months. Patients in the AF screw-rod system group were followed up for 8-14 months, averagely 12.1 months. (2) Curative effects: Compared with the AF screw-rod system group, blood loss, drainage volume, Cobb angle and Visual Analogue Scale scores were decreased in the paraspinal approach combined with internal fixation through pedicle of fractured vertebra group (P < 0.05), but fractured vertebra reduction rate was increased (P < 0.05); conscious symptoms and neurological function improvement of ASIA grading evaluation were better in the paraspinal approach combined with internal fixation through pedicle of fractured vertebra group than in the AF screw-rod system group (P < 0.05). (3) Paraspinal approach combined with internal fixation through pedicle of fractured vertebra obtained better clinical effect than AF screw-rod system in the treatment of thoracolumbar fractures.
