BACKGROUND: A systematic literature review of interspinous dynamic stabilization, including DIAM, Wallis, Coflex, and X-STOP, was conducted to assess its safety and efficacy. METHODS: The search was done in Korean and English, by using eight domestic databases which included KoreaMed and international databases, such as Ovid Medline, Embase, and the Cochrane Library. A total of 306 articles were identified, but the animal studies, preclinical studies, and studies that reported the same results were excluded. As a result, a total of 286 articles were excluded and the remaining 20 were included in the final assessment. Two assessors independently extracted data from these articles using predetermined selection criteria. Qualities of the articles included were assessed using Scottish Intercollegiate Guidelines Network (SIGN). RESULTS: The complication rate of interspinous dynamic stabilization has been reported to be 0% to 32.3% in 3- to 41-month follow-up studies. The complication rate of combined interspinous dynamic stabilization and decompression treatment (32.3%) was greater than that of decompression alone (6.5%), but no complication that significantly affected treatment results was found. Interspinous dynamic stabilization produced slightly better clinical outcomes than conservative treatments for spinal stenosis. Good outcomes were also obtained in single-group studies. No significant difference in treatment outcomes was found, and the studies compared interspinous dynamic stabilization with decompression or fusion alone. CONCLUSIONS: No particular problem was found regarding the safety of the technique. Its clinical outcomes were similar to those of conventional techniques, and no additional clinical advantage could be attributed to interspinous dynamic stabilization. However, few studies have been conducted on the long-term efficacy of interspinous dynamic stabilization. Thus, the authors suggest further clinical studies be conducted to validate the theoretical advantages and clinical efficacy of this technique.

OBJECTIVETo investigate the perioperative characteristics and surgical methods in treating the old with degenerative lumbar spinal stenosis.
METHODSFrom January 2000 to October 2007, 36 patients with degenerative lumbar spinal stenosis with the age more than 60 years,including 16 males and 20 females, the age from 60 to 81 years with an average of 67.5 years. Of all patients, 6 cases were treated by simple surgical decompression, 16 cases by decompressive laminectomy, 20 cases by decompressive laminectomy combined with internal fixation and fusion.
RESULTSNo death cases occurred during perioperation and complication occurred in 14 cases, including cerebrospinal fluid leakage in 3 cases, incision late healed in 1 case, heart abnormal symptom in 1 case, respiratory infection in 1 case, gastrointestinal symptom in 4 cases, urinary system infection in 1 case, spirital symptom in 1 case. After symptomatic treatment, all complications improved. All the cases were followed up from 6 months to 5 years with an average of 2.5 years. Oswestry scoring improved from preoperative 45.66 +/- 7.12 to postoperative 16.80 +/- 5.75, there was significant difference between before and after operation (P < 0.05).
CONCLUSIONThe age and heath condition are not operative absolute contraindication in treating old with degenerative lumbar spinal stenosis,with the proper operation modus after controlling concomitant diseases, the surgical treatment could guarantee the satisfactory therapeutic effect.

PURPOSE: To examine the effects of conservative and surgical treatments for nocturnal leg cramps in patients with lumbar spinal stenosis (LSS). Nocturnal leg cramps is frequently observed in patients with peripheral neuropathy. However, there have been few reports on the relationship between nocturnal leg cramps and LSS, and it remains unknown whether conservative or surgical intervention has an impact on leg cramps in patients with LSS. MATERIALS AND METHODS: The subjects were 130 LSS patients with low back and leg pain. Conservative treatment such as exercise, medication, and epidural block was used in 66 patients and surgical treatment such as decompression or decompression and fusion was performed in 64 patients. Pain scores and frequency of nocturnal leg cramps were evaluated based on self-reported questionnaires completed before and 3 months after treatment. RESULTS: The severity of low back and leg pain was higher and the incidence of nocturnal leg cramps was significantly higher before treatment in the surgically treated group compared with the conservatively treated group. Pain scores improved in both groups after the intervention. The incidence of nocturnal leg cramps was significantly improved by surgical treatment (p=0.027), but not by conservative treatment (p=0.122). CONCLUSION: The findings of this prospective study indicate that the prevalence of nocturnal leg cramps is associated with LSS and severity of symptoms. Pain symptoms were improved by conservative or surgical treatment, but only surgery improved nocturnal leg cramps in patients with LSS. Thus, these results indicate that the prevalence of nocturnal leg cramps is associated with spinal nerve compression by LSS.

OBJECTIVETo investigate the clinical characteristics and results of cervical spinal cord injury (SCI) in the patients with ossification of the posterior longitudinal ligament (OPLL).
METHODSNineteen patients with cervical SCI associated with OPLL were retrospectively analyzed. Data collection included: pre- and postoperative neurological function, OPLL-type, MRI signal changes and surgical approaches.
RESULTSSpinal cord associated with OPLL was injured severely by mild trauma. Methylprednisolone sodium succinate was used within 8 h after trauma in 12 cases. Two of them died of complications. The neurological functions were markedly improved in the other 10 cases. Seventeen cases had surgical treatment. The neurological functions (Frankel grade) were improved significantly in the operated patients except for one, who died 27 d after operation.
CONCLUSIONSThe patients with OPLL are prone to have severe SCI, which directly associates with the preexisting OPLL-type and hyper-intensity signal change in the spinal cord on MRI. Both of using methylprednisolone sodium succinate administration within 8 h after trauma and surgical decompression may improve the neurological outcomes.
