A 24-year-old man with tuberculosis meningitis developed acute paraplegia and sensory disturbances 5 weeks after receiving conventional antituberculous therapy. Magnetic resonance imaging revealed an intradural extramedullary long segmental mass mimicking en plaque meningioma at the T2-T6 vertebrae levels. Prompt surgical decompression was performed. A histology examination of the mass revealed a tuberculoma. After surgery, the patient showed improved motor power and a normal bladder function. Intradural extramedullary tuberculoma of the spinal cord is rare complication of tuberculosis meningitis, which can occur as a response to conventional antituberculous therapy.

PURPOSE: The purpose of this study is to evaluate the usefulness of locally harvested bone in anterior cervical interbody fusion. MATERIALS AND METHODS: A retrospective review was conducted, including 31 patients who underwent anterior cervical interbody fusion using a polyetheretherketone (PEEK) cage and anterior plate fixation. We randomly divided the patients into two groups, local bone group and iliac bone group. In 15 patients of the local bone group, the cage was filled with locally harvested bone, and in another 16 patients of the iliac bone group, the cage was filled with autogenous iliac bone. RESULTS: Improvements in mean visual analogue scale (VAS) scores, from 5.8 and 7.7 to 1.6 and 2.3 for neck pain and arm pain, respectively, were observed in cases using locally harvested bone, while the improvements were from 5.7 and 7.2 to 1.4 and 2.2, respectively, in those using autogenous iliac bone grafts. However, no significant differences in mean VAS and neck disability index were observed between the two groups at the last follow up (p>0.05). Radiologic union was achieved at 14.0+/-2.50 weeks in the local bone group, and at 12.62+/-1.58 weeks in the iliac bone group. However, no significant difference was observed between the two groups (p=0.076). CONCLUSION: Utilization of locally harvested bone for packing in a PEEK cage for anterior cervical interbody fusion is considered a useful method because it gives satisfactory clinical results for retention of bone union and lordosis angles.

Restless legs syndrome (RLS) is a neurogenic disorder with the patients having a sensation of discomfort and an urge to move continuously. These symptoms can get worse during night and cause sleep disturbance. These symptoms can be misdiagnosed as lower leg pain of a spinal origin and the treatment can be wrongly focused on this. This treatment for an unproven state of symptoms can place clinicians in a difficult situation. We experienced RLS associated with spondylolisthesis and spinal stenosis, and we originally misdiagnosed the patient and wrongly treated the patient operatively with spinal fusion and posterior instrumentation. After an insufficient result, we diagnosed the patient with having RLS with the help of the neurology department and rehabilitation medical department. In one other case we diagnosed a RLS patient with the help of a neurologist and the patients had arrived an our department for total knee arthroplasty and spinal root block. We report on these cases so other orthopedic surgeons will not make same mistakes.

PURPOSE: We reported relative risk of operation between patients who were diagnosed with lumbar far lateral disc herniation and posterolateral disc herniation after transforaminal epidural block. MATERIALS AND METHODS: A retrospective cohort study was performed on 295 patients (131 male and 164 female) who underwent transforaminal epidural block for unilateral radiculopathy caused by lumbar intervertebral disc herniation. Among these 295 patients, 34 patients were diagnosed with far lateral disc herniation and 261 patients with posterolateral disc herniation. The median follow-up period was 23.9 months, with an average age of 55.7 years. RESULTS: Fifty-one patients underwent surgical treatment. Among them, 38 patients had posterolateral disc herniation and 13 patients had far lateral disc herniation. Patients with far lateral disc herniation, when compared with posterolateral disc herniation, had a relative risk of operation of 2.67 (1.59-4.48, 95% confidence interval) with statistical significance (p=0.0002). At the final follow-up, the average visual analogue scale (VAS) score for radicular pain in the surgical and non-surgical groups was 0.69 and 1.50, respectively; the average Korean-Oswestry Disability Questionnaire (K-ODI) score was 11.7 and 9.6, respectively. The difference of average VAS score showed a statistical significance (p=0.035), however, that of K-ODI showed no statistical significance (p=0.266). CONCLUSION: In the case of far lateral disc herniation, the relative risk of surgery after transforaminal epidural block was 2.67, which is higher than that of posterolateral disc herniation. Therefore, we should consider surgical treatment more aggressively.

OBJECTIVES: We analyzed the radiological results of the double-balloon inflation technique in terms of its ability to reduce cement leakage, to increase bone cement bonding, and to promote anterior column height recovery.SUMMARY OF LITERATURE REVIEW: Various methods, such as the egg-shell technique, have been proposed to prevent leakage of cement during kyphoplasty in cases of osteoporotic compression fracture. MATERIALS AND METHODS: This study analyzed 18 patients diagnosed with osteoporotic compression fracture of the lumbar spine who underwent the double-balloon inflation technique after April 2015, and 30 consecutive patients with the same diagnosis who were treated using the conventional method prior to April 2015. We analyzed the radiological results on immediate postoperative simple X-rays in the anteroposterior and lateral views, 6-week postoperative lateral X-rays, and 6-month postoperative lateral X-rays to detect changes in anterior vertebral height and the cement leakage rate. RESULTS: The average anterior vertebral height increased by 7.58 mm in the double-balloon inflation group, and by 5.8 mm in the conventional group on the immediate postoperative radiographs (p=0.044). On average, a decrease of 3.08 mm was observed at 6 weeks postoperatively in the double-balloon inflation group, in contrast to a decrease of 4.68 mm in the conventional group (p=0.149). At the 6-month postoperative follow-up, an average decrease of 1.45 mm was found in the double-balloon inflation technique group, while a decrease of 1.40 mm was found in the conventional group (p=0.9110). The cement leakage rate was 22% in the double-balloon inflation group and 27% in the conventional group (p=0.730). CONCLUSIONS Compared to the conventional method, the double-balloon inflation technique can be done more safely, and also promotes a greater recovery of anterior vertebral height.
