Chinese Journal of Flood Control, 199214 (4) 155 pedicle screw internal fixation for thoracolumbar fractures and slippage. Department of Thoracic and Thoracic Fractures in Hu's Spine Fracture in Panjiang Mine Hospital of Panjiang (Coal Power) Group, Guizhou Province (Panxian 561321) Most common, and often hurt the spinal cord.
Early correct surgical treatment can prevent secondary damage to the spinal cord and contribute to the recovery of residual spinal cord function. In our hospital from August 1997 to September 2000, a total of 36 cases of thoracolumbar fractures with or without slippage were treated with pedicle screw internal fixation and bone grafting. The results are as follows.
1 Materials and Methods 1.1 Case data 36 patients in this group were male, aged 18-56 years. The cause of the injury was bruises. Post-injury to hospitalization time: 30 cases 1 to 6 hours, 4 cases 1 to 2 days, 2 cases 3 to 4 days. There were 28 cases of flexion compression, 1 of which were compression fractures of T8 and T12~Li. 4 cases of burst type. There were 4 cases of fracture with slip. The fracture site: T81 cases, 22 cases of Tn3, and 8 cases of total sputum. 28 cases of bone grafting.
2 surgical methods continue epidural anesthesia. Prone position, posterior median incision revealed lamina, articular processes and transverse processes. Determine the fracture vertebral body to accurately insert the pedicle screw into the upper and lower vertebrae of the injured vertebrae. Apply Steffee's case and insert a pair of pedicle screws into the injured vertebrae, install the connecting rod or Stefe plate, adjust the operation. The bed is placed in the posterior position of the spine, and the head and tail are properly pulled under the abutment to correct the kyphosis of the fracture, restore the height of the compressed vertebral body, and tighten the nut. Cases using Steffee plates can simultaneously push and pull the fractured vertebral body. Reset it and tighten the nut to secure it. If the combined spinal cord function is impaired or the compression and slippage is severe, laminectomy and decompression and spinal canal exploration should be performed after pedicle screw fixation. At the same time, it can be directly squeezed to reset or remove the fracture block protruding into the spinal canal in front of the spinal canal. Place the gelatin sponge on the epidural to stop the bleeding, take the posterior lateral bone graft of the humerus, and place the negative pressure for 2 days. In this group of cases, 2 results of this group of incisions were healed in the first stage. The X-ray positive lateral radiograph showed that 30 cases had a good reduction, 5 cases were mostly repositioned, and 1 case was severely slipped. There was still a degree of spondylolisthesis after operation, but the signs of spinal cord compression were significantly relieved. There were 22 cases of preoperative sputum, all of which had different degrees of functional recovery, and they were able to take care of themselves and partially resume light physical work. There were 8 cases of complete paraplegia, and none of them recovered. In some cases, the back of the back was stiff, and the back pain disappeared after removal and internal fixation. All the cases were followed up for 6 months to 2 years. The deformity was satisfactory and all bone grafts were healed.
3 Discussion According to the anatomical classification, the entire spine is composed of 33 vertebrae. The violence is transmitted along the spine, and the vertebrae at the junction between the stable part of the spine and the active part often form damage. Thoracolumbar section. (Tm * L) The spine is more active at the junction and is most often injured. And the vast majority is caused by indirect violence. For example, when falling from a high altitude or bending over, heavy objects fall on the head, shoulders, back, etc., causing the spine to bend rapidly. The patients in this group were caused by the meteorites on the shoulders of the underground workers or the help of the column. The cause was clear, the violence was serious, the condition was serious, and the spinal cord injury was often accompanied.
Some authors believe that vertebral compression injury is the main cause of spinal deformity and an important cause of spinal cord injury. 1 Therefore, restoring the necessary height of the vertebral body is one of the important purposes of the treatment of most thoracolumbar fractures, and restores the morphology of the spinal canal. It is closely related to relieving spinal cord compression.
Early surgery to reconstruct the stability of the spine is beneficial to relieve spinal canal compression, promote the recovery of residual spinal nerve function and prevent secondary spinal cord injury.
There are many kinds of spinal internal fixation equipment. Our hospital commonly used posterior Dick nail and Steffee steel plate, both of which are short-segment pedicle internal fixation system, can play a role in the reduction and fixation of the vertebral body, and the fixed vertebral body segment is short and stable. The three columns of the spine are fixed, and the multi-segment holders such as the Lugue rod are convenient and practical, and the movement function of the spine is retained to the utmost extent. After many cases of surgery, the author believes that the operation of the Steffee plate internal fixation system is easy to grasp, reliable and reliable, and has a large reduction force. It has a push-pull lifting effect on the slip-off vertebra. The intraoperative reduction is easier than the Dick nail system, and the internal fixation is also better. Dick nails are simple. Fracture vertebral reduction can be indirectly decompressed, but for the severe dislocation, spinal cord function is impaired, laminectomy and decompression, spinal canal exploration is necessary. However, it cannot be considered that simple laminectomy and decompression can replace the fixation of the injured vertebra. Simple laminectomy and decompression can not relieve the fundamental problem of compression from the anterior segment of the spinal canal, and it will also increase the instability of the spine. 2. Place the gelatin sponge to stop bleeding during the epidural surgery to reduce the nerve adhesion caused by postoperative scar. And oppression of the spinal cord.
The stability obtained by firm internal fixation is temporary, and long-term stability must be achieved by interbody fusion. Therefore, bone grafting after the reduction and fixation of the fractured vertebra can ensure long-term stability between the vertebral bodies. And effectively reduce the incidence of loosening of the internal cause of the device and the incidence of re-fracture.
