Caudal analgesia is a widely accepted technique for providing pain relief. However, both permanent and transient neurologic complications, including paraplegia, have been reported. We report on a patient who developed paraplegia following a caudal block for an epidural mass. The cause of the paraplegia was unknown, but possibly spinal angioma may have taken part in the onset and progression of the paralysis. A mechanism is proposed by which the caudal injection may have caused a change in blood flow through the spinal angioma resulting in cord ischemia.

We experienced five cases of solitary fibrous tumor; two in the pleura, two in the orbital soft tissue, and one in the lung parenchyma. Three patients were male, and the age of the patients ranged from 38 to 71 years (mean age: 53.6). Grossly, the masses were well circumscribed and had varying sizes from 2.5 to 30.0 cm. The cut surfaces were grayish-yellow firm with focal variegated hemorrhage, necrosis, cystic change, and myxoid area. Microscopically, these were characterized by a haphazard proliferation of spindle cells or polygonal cells separated by variable amounts of hyalinized collagen and showed a prominent vascular channels reminiscent of hemangiopericytoma in foci. Immunoperoxidase stains showed a strong reactivity for CD34, and were weakly positive for vimentin. Electron microscopical examination revealed features of fibroblast; spindle to round tumor cells were arranged in groups and surrounded by collagen. Nucleoli were seldom prominent. The cytoplasm contained many microfilaments and a moderate number of cisternae of rough endoplasmic reticulum.

Klippel-Trenaunay syndrome is a rare congenital mesodermal abnormality characterized by varicose veins, cutaneous hemangiomas, soft tissue and bony hypertrophy of limb. Potential complications such as deep venous thrombosis and pulmonary thromboembolism have not been reported in Korea to date. We demonstrate the case of a 48-year-old woman with Klippel-Trenaunay syndrome with extensive varicose veins on right lower limb, hypertrophy of left big toe and basilar artery tip aneurysm, complicated with acute submassive pulmonary thromboembolism treated successfully with intravenous thrombolytic therapy.

STUDY DESIGN: A retrospective study. OBJECTIVES: This study analyzed the clinical and radiographic results of the posterior lumbar interbody fusion performed on patients 50-65 and >7-years-of-age suffering from degenerative lumbar disease. LITERATURE REVIEW SUMMARY: Several studies on posterior lumbar interbody fusion performed on patients aged about 65 years reported insignificant age-related differences in the spinal-fusion results. MATERIALS AND METHODS: The records of 121 patients with degenerative lumbar disease treated with posterior lumbar interbody fusion between 2004 and 2010 were assessed. The patients' clinical results, visual analogue scale (VAS) scores, Oswestry disability index (ODI) values, and complications before and after the surgery were compared. The radiographic results and changes in the fusion segmental angle before and after the surgery as well as in the height of the posterior intervertebral disc were also compared. RESULTS: In group A, comprising 44 patients >70-years-of-age, follow-up duration and number of comorbidities were 73.3 years and 17.8 months, respectively. In group B, comprising 77 patients 50-65-years-of-age, follow-up duration and number of comorbidities were 58.8 years and 31.8 months, respectively. In both groups, the average VAS scores and ODI values decreased. The incidence rate of vertebra-related postoperative complications was 13.6% in group A and 9.0% in group B. The incidence rate of general complications unrelated to the vertebra, was 18.1% in group A and 9.0% in group B. CONCLUSIONS: Posterior lumbar interbody fusion is considered effective even in patients over 70 years with a degenerative lumbar disease.

Purpose: To evaluate the relationship between distal fusion level in correction and fusion surgery for adolescent idiopathic scoliosis (AIS) and radiologic changes in the sacroiliac (SI) joint. Materials and Methods: This retrospective cohort study evaluated patients who underwent correction and fusion for AIS between 2005 and 2017 with at least 5 years of follow-up. We categorized patients into two groups: Group 1 (distal fusion above L2, 74 patients) and Group 2 (distal fusion at L3 and below, 52 patients). Radiologic parameters and SI joint changes were evaluated on plain radiographs obtained from preoperative to 5 years postoperatively. We also investigated other risk factors for SI joint change. Results: Analysis of demographic factors revealed no significant difference between the two groups. There was a significant difference in the incidence of SI joint change between Group 1 (5 patients, 6.75%) and Group 2 (18 patients, 34.61%), with Group 2 showing a faster increase in incidence according to the Kaplan-Meier method (p<0.0001). Preoperative lumbar lordosis (LL) and ΔLL had a significant relationship with SI joint changes [preoperative LL, hazard ratio (HR)=0.77, 95% confidence interval (CI)=0.64– 0.93, p=0.008; ΔLL, HR=0.79, 95% CI=0.67–0.95, p=0.01). Conclusion After AIS surgery, patients who had fusion to the lower lumbar vertebrae (L3 or L4) experienced a higher incidence and faster progression of degenerative changes in the SI joint. Low preoperative LL and inadequate correction of LL during the operation were also risk factors for SI joint degeneration.

Background: To identify the optimal surgical technique for single-level anterior cervical discectomy and fusion (ACDF), this study compared surgical outcomes and incidence of adjacent segment degeneration (ASD) in patients undergoing single-level ACDF using cage alone single-level fusion and plate fixation techniques. Methods: This single-center retrospective study (2003–2018) included patients who underwent single-level ACDF with either plate fixation (PLATE) or cage (CAGE) alone. The radiologic and clinical outcomes between the 2 surgical groups were compared over a 4-year follow-up period. Outcomes of interest included parameters related to range of motion, sagittal alignment, as well as fusion, subsidence, and ASD rates. Clinical outcomes were evaluated using the Neck Disability Index (NDI) and visual analog scale (VAS) for pain. Dysphagia and hoarseness rates were estimated based on medical records. Results: Forty-seven patients were included (n=17 in CAGE group). In the CAGE group, 94.1% of the patients had Bridwell grade 1 or 2, compared to 83.3% in the PLATE group (p = 0.396). Subsidence occurred in 12.5% and 3.6% of the CAGE and PLATE cases, respectively (p = 0.543). Segmental kyphosis progressed in the CAGE group compared to the PLATE group at 12, 24, and 48 months (p < 0.001). Radiographic ASD was observed in 41.2% and 30.0% of patients in the CAGE and PLATE groups, respectively, with a higher incidence in the upper segments for both groups. Preoperative NDI scores were similar between the groups; however, postoperatively, the CAGE group had significantly lower NDI scores (3.50 ± 2.74 vs. 8.00 ± 5.81) at 4 years (p = 0.020). Neck pain VAS scores also showed significant improvement in the CAGE group (2.33 ± 2.94) compared with that in the PLATE group (3.07 ± 2.31) at 4 years (p = 0.045). Both groups showed comparable arm pain VAS scores at 2 and 4 years postoperatively. Postoperative dysphagia occurred in 1 patient in the PLATE group, resolving almost completely by 1 year. Conclusions Single-level ACDF using a cage alone technique demonstrated favorable radiologic and clinical outcomes overall compared to plate-augmented ACDF. However, plate augmentation is recommended for patients with severe cervical kyphosis or those at high risk of subsidence.
