Abstract:
STUDY DESIGN: A retrospective study. OBJECTIVE: To analyze the outcome of the surgical treatment for lumbar spinal stenosis with fracture in multiple osteoporotic vertebral body compression fractures. SUMMARY OF LITERATURE REVIEW: An osteoporotic vertebral compression fracture, without neurological symptom, has mainly been treated with conservative care. Sometimes, vertebroplasty or kyphoplasty has been used as a surgical treatment. In the case of a single thoracolumbar fracture with neurological symptoms, not improved by conservative care, decompression, fusion and instrumentation through an anterior or a posterior approach has been attempted. MATERIALS AND METHODS: 10 patients, who had received surgical treatment for symptomatic lumbar spinal stenosis with fracture out of those with multiple osteoporotic vertebral body compression fractures, and over the age of 60, were assessed. The surgical treatment was performed on the patient with all of the following five criteria; (1) severe back pain caused by fractures, (2) neurological symptoms of lumbar spinal stenosis, (3) radiological evidences of stenosis by lumbar fracture, (4) no response to conservative treatment for over 3 months, and (5) adequate physical ability for daily living without a severe medical condition. The surgical procedure included: decompressive laminectomy, posterior instrumentation using pedicle screw fixation, and fusion in situ. The pedicle screws were located 2-3 above and below the most cephalad and caudad fractured vertebral bodies. RESULTS: Clinically, favorable results were obtained in 8 of the 10 patients. In the roentgenographic assessment, the operated states were well maintained, without the metallic failure or instability. Halos around the pedicle screws were seen in 4 patients, but there was no significant evidence of loosening. There were no serious medical and systemic complications in the peri- and postoperative periods. Additional vertebral body fractures and pain were seen in 5 patients, but they had been well managed, conservatively. CONCLUSION: Favorable clinical results could be expected for the surgical treatment of lumbar spinal stenosis, with fracture, in the patients with multiple osteoporotic vertebral fractures, as long as the surgical treatment was indicated exactly and carefully.
