  Our purpose in this study was to determine the results of CT fluoroscopy guided Percutaneous Vertebroplasty (PVP) in pain reduction from vertebral compression fractures and its complications. During a 3 year period, 59 patients (39 female, 20 male) with persistent low back pain and back pain underwent percutaneous injection of cement into the vertebrae under fluoroscopic guidance. Among our patients, 30 cases (50.8%) had thoracic pathology, 26 (44.1%) lumbar pathology and 3 (5.1%) both thoracic and lumbar involvement. Severity of low back pain and back pain was assessed by using visual analog scale (VAS) before and after one and 6 months intervals thereafter. The mean age of our cases was 63.5±11.3 years (range: 25-97). Thirty two procedures (54.3%) were performed for osteoporotic compression fracture, 13 (22%) for hemangioma, 9 (15.3%) for traumatic fracture and 5 (8.5%) for metastasis. Mean volume of cement injected was 5.3±1.6 mL (3-10 mL) in osteoporotic vertebrae, 4.7±1.4 mL (2-7 mL) in hemangiomas, 6.2±2.4 mL (3-10 mL) in traumatic fractures and 4.4±0.9 mL (4-6 mL) in vertebrae affected by metastasis (p = 0.17). Reduction in pain immediately after the procedure was seen in 71.9% (23 from 32 cases) for osteoporosis 77.8% (14 from 18 cases) for tumoral lesions and 55.6% (5 from 9 cases) for traumatic fractures (p = 0.48). Mean pain reduction after 6 months was significantly higher than mean reduction after one month (55.9±24.9% versus 45.7±24.8%; p<0.0001). CT fluoroscopy guided PVP is a safe and efficacious procedure resulting in pain reduction among patients with vertebral compression fractures.

  Low back pain is one of the most common causes of disability for individuals of working age in developed countries. Along with vast traumatic, infectious, tumors and infiltrative causes, degenerative disk transformations have been accepted as major etiologic factors. Lumbosacral Transitional Vertebra (LSTV) is one of the congenital factors that might cause disk degeneration. The purpose of this research is to assess the type and frequency of pathological findings in adjacent vertebra in a group of Iranian patients with LSTV. Patients and methods: In a cross sectional study between April 2006 and September 2007, we evaluated all patients who indicated to do lumbosacral MRI because of low back pain. All patients had Lumbar X-ray. Among them, considering plain AP lumbar spine x-ray for all patients, 91 patients were determined to have LSTV (Castelvi grade 2-4) that were enrolled in the study. Among 91 patients with LSTV, 58 (63.7%) were females (p = 0.01). The LSTV type IIIb (28.6%) was the most common type. The frequency of anterior osteophyt reached to its peak in level L4-L5 (51.6%) (p<0.0001). Such a trend was seen in posterior osteophyt. The frequency of the facet hypertrophy in the level L4-L5 was 46.2% and in the level L5-S1 was 31.9% (p = 0.04). Moreover, the frequency of the flavum ligament hypertrophy in these levels were 38.5 and19.8%, respectively (p<0.0001). The mean severities of disk degeneration in levels L4-L5 and L5-S1 were 2.8±1.3 and 2.5±1.3, respectively (p = 0.022). The frequency of disk herniation in the level L4-L5 was 67% and in the level L5-S1 was 34.1% (p<0.0001). In addition, the mean severities of disk herniation in these levels are 1.3±1.0 and 0.6±1.0, respectively (p<0.0001). Finally, the mean value of the disk height in the level L4-L5 was 9.6±2.0 mm and in the level L5-S1 was 7.4±2.6 mm (p<0.0001). It seems that pathologies have been increased in the level above the LSTV in compare to the level below it.

  > Disc protrusion is a very common disorder and usually responds to conservative treatment, but in some patients surgical interventions are inevitable. Percutaneous Laser Disc Decompression (PLDD) is an interventional procedure replacing surgery in some cases of disk protrusion. This study was conducted to evaluate the results of CT guided PLDD. PLDD was performed on 40 patients, who didn't respond to conservative therapies for protrusion. The intervention was carried as an out patient therapy and patients were followed for one year. One week after PLDD, 32 patients (80%) were satisfied with the intervention. At 1, 6 and 12 months follow ups; 31 patients (77%), 30 (75%) and 28 (70%) were satisfied, respectively. No significant complication occurred during the procedure. CT guided PLDD is a useful therapeutic modality in patients suffering disc protrusion which don't respond to conservative treatment.
