BACKGROUND:Spinal canal decompression reduction fixation combined with bone graft fusion has been extensively applied in the clinic. Bilateral pedicle screw assisted interbody fusion and unilateral pedicle screw assisted interbody fusion are main methods to treat degenerative lumbar spinal stenosis and lumbar spondylolisthesis. OBJECTIVE:To compare early clinical therapeutic effects of bilateral and unilateral pedicle screw assisted interbody fusion in elderly patients with spinal stenosis and degenerative spondylolisthesis. METHODS:A total of 60 elderly patients with spinal stenosis with degenerative lumbar spondylolisthesis were selected, including 37 males and 23 females, at the age of 60 to 78 years old. They were divided into two groups, and subjected to decompression of spinal canal. In the treatment group (n=30), patients received unilateral pedicle screw assisted interbody fusion. In the control group (n=30), patients received bilateral pedicle screw assisted interbody fusion. After treatment, they were folowed up for 1 year. The recovery of joint function was assessed using Japanese Orthopaedic Association scores in both groups. Simultaneously, complications were recorded. RESULTS AND CONCLUSION:Japanese Orthopaedic Association scores were 25.7±1.9 and 25.8±1.8 in the treatment and control groups, respectively, and no significant difference was found between groups. In the treatment group, three cases affected lower limb numbness and two cases suffered from dural tear, with the incidence of complication of 17%. In the control group, three cases affected lower limb numbness and three cases suffered from dural tear, with the incidence of complication of 20%; no significant difference was detected between the two groups. No adverse reaction related to bone graft was found in the two groups. These results confirm that bilateral or unilateral pedicle screw assisted interbody fusion in treatment of degenerative lumbar spondylolisthesis with spinal stenosis obtained good therapeutic effects.

BACKGROUND:Conventional cross-segment pedicle screw fixation wil cause some complications such as kyphosis and loss of corrective angle. Fixation of pedicle screw placement of the injured vertebral body improves the disadvantages of conventional posterior screw placement, and obtains ideal outcomes. OBJECTIVE: To investigate the clinical application value of pedicle screw placement combined with filer for lumbar vertebra fracture. METHODS: Clinical data of patients with pedicle screw placement combined with filer for lumbar vertebra fracture were retrospectively analyzed. They were repaired with pedicle screw placement combined with bone graft as wel as pedicle screw placement combined with bone cement. The ratio of anterior border to posterior border of the injured vertebral body after surgery and changes in Cobb angle were observed. Patients were folowed up and results were compared. RESULTS AND CONCLUSION: Pedicle screw placement combined with filer has many advantages, and obtained good outcomes in the treatment of lumbar vertebral fracture. However, the extensive application has some problems and disputes. Clinical physicians should pay more attention on choice of surgical indications, prevention and treatment of perioperative and long-term complications and postoperative treatment of osteoporosis. The pedicle screw fixation combined with calcium phosphate bone cement has a broad prospect, can maintain the effect of spine reduction, and is worth to spread in the clinical treatment of lumbar fractures.

BACKGROUND:Traumatic or iatrogenic dural defects can cause persistent cerebrospinal fluid leakage, even progressing to life-threatening purulent meningitis. In patients with meningitis combined with cerebrospinal fluid leakage, most antibiotics are unable to enter the cerebrospinal fluid, as the cerebrospinal fluid is a good medium for bacteria and there is the presence of blood-brain barrier. So meningitis presents with acute onset, rapid development and infection difficult to control. OBJECTIVE:To evaluate the outcome of continuous lumbar subarachnoid drainage plus intrathecal administration of antibiotics for postoperative cerebrospinal fluid leakage combined with meningitis after biomaterial repair of dural defects. METHODS: A retrospective study was carried out to review the 12 cases of cerebrospinal fluid leakage combined with meningitis among 126 of 2 266 cases who developed cerebrospinal fluid leakage (5.56%) undergoing spinal surgery from June 2008 to June 2013. During the operation, dural defects were directly sutured or repaired with autologous fascial sheet. Al cases underwent thorough debridement and intravenous injection of sensitive antibiotics folowed by continuous lumbar drainage and intrathecal administration of sensitive antibiotics (usualy vancomycin), and then the incision was closed at stage I. RESULTS AND CONCLUSION:The cerebrospinal fluid leakage was found in the 12 cases at 24-72 hours after surgery, averagely 48 hours; the infection was found at 812 days days after surgery, averagely 9.5 days. Headache and fever were significantly relieved at the 2nd day of intrathecal administration of antibiotics, and intracranial infection disappeared at 7-14 days after continuous lumbar drainage. Biochemical test of the cerebrospinal fluid and routine examination were done thrice, and the results were al normal. No bacterial growth was found in bacterial culture test, and the drainage tube was removed. There was no intraspinal infection, intracranial hypotension headache and hernia caused by the drainage tube. These findings indicate that autologous fascia repair combined with continuous lumbar subarachnoid drainage plus intrathecal administration of antibiotics is an effective method in the treatment of cerebrospinal fluid leakage with meningitis.
