ABSTRACT
OBJECTIVE: To investigate the effects of arc-track private lock pedicle orthopedic fixation system Ⅱ (ALPF Ⅱ) on treatment of spinal diseases. METHODS: A total of 86 patients with spinal diseases were treated using self-made ALPF in the Wendeng Orthopaedic Hospital and were included in this study. Of these patients, 14 suffered from cervical spinal stenosis complicated by cervical vertebral destabilization, 29 from thoracolumbar fractures and dislocations, 15 from lumbar spinal stenosis complicated by lumbar vertebral destabilization, 2 from lumbar spondylolisthesis, 8 from spinal tuberculosis, 6 from ankylosing spondylitis, 9 from idiopathic scoliosis, and 3 from congenital scoliosis. According to conditions, different therapeutic regimens were selected. Postoperatively, regular follow-up was performed to observe vertebral healing, intervertebral height, spinal column sequence, and neurological function recovery. RESULTS: All patients were followed up for 9-30 months (average 12 months). The improvement rate of neurological function, spinal mobility, back pain, and melosalgia was 94.1%, 65.9%, 92.1%, and 87.4%, respectively. The postoperative anterior and posterior vertebral heights were apparently recovered, and kyphotic angle was well corrected. No screw, rod loosening or breakage was found. CONCLUSION: Self-made ALPF Ⅱ is an internal fixation method for treatment of spinal diseases. It provides good reduction, reliable curative effects, less complications, and no biocompatibilities.
ABSTRACT
OBJECTIVE To explore the sterilizing effect of low-temperature vacuum formaldehyde.METHODS The test group used the own-produced 140 L low-temperature vacuum formaldehyde sterilizer for sterilization;and the control group used "Xinhua" hydrogen peroxide plasma sterilizer.Sterilization effect of the two groups was monitored by biological indicator.RESULTS After 50 sterilization procedures run in test group,the biological indicators the bacterial were all killed,the qualification rate of sterilization was 100%.But after 30 sterilization procedures run in control group,only 8 procedures were qualified,the qualification rate of sterilization was 26%.The sterilizing effect of the two groups was significantly different(P
ABSTRACT
[Objective]To explore the feasibility and outcome of posterior single open-door and pedicle screw in treating canal stenosis and instability of cervical vertebrae at one time.[Method]The preoperative radiographs of 15 patients were measured and were diagnosed to be developmental spinal canal stenosis and instability of cervical vertebrae.MRI showed the spinal cords were compressed obviously.Posterior C_(3~7) single open-door decompression and canal-plasty was adopted.Self-designed pedicle screws and intertransverse fusion were used in the unstable segments.[Result]Complications were not found after the operation.The postoperative radiographs showed that the screws were in the right places.The average follow-up time was 13 months,ranging from 7 to 18 months.The short-term radiographs showed firmly fixed screws.[Conclusion]It is a simple and reliable method to treat canal stenosis and instability of cervical vertebrae at one time with posterior single open-door and pedicle screw.Anterior and posterior operations have been avoided and the short-term outcome is satisfied.
