Sažetak
The patients with intensive pain caused by the vertebra body fracture were treated by application of low viscosity cement (LVC),(Vertebroplastic, DePuy) and high viscosity cement (HVC),(Confidence, DePuy,) into the body, by means of diascopy through unilateral transpendicular approach. Application of LVC was made in 75 patients, on 109 vertebrae, and HVC was applied in 12 patients on 14 vertebrae. Application of LVC was performed on 48 thoracic and 61 lumbar vertebrae and 5 thoracic and 9 lumbar vertebrae were stabilized with HVC. 43 patients were treated for malignancy and in 38 for osteoporosis. For LVC, preoperative VAS score was 8.32 and 2.23 (p<0.00001) 24 hours after surgery, and it remained stable 3 month later. For HVC, preoperative VAS score was 7.99 and it was 2.5 (p<0.00001) 24 hours after surgery and 3 months later. In the group of patients treated with LVC, there was 1 serious complication, a paraparesis caused by the leakage of cement into the spinal canal, which was partially recovered after decompression and rehabilitation treatment and 2 superificial infections with S. epidermidis which were cured by means of antibiotics. In 32 vertebrae (32) cement leakage extra ossal, either into vein plexus or intradiscal during surgery were noticed. When HVC was applied, intradiscal leakage occurred in one case onl (8%). By means od Wilcoxon paired test a significant difference was found between the preoperative VAS, and the values immediately after surgery and 3 months later (Z=7.52, p<0.00001) when LVC was applied., and with HVC it was (Z=3.04, p<0.00001), which indicates that the fast achieved pain reduction remained stable during the 3 month follow-up. The vertebroplasty is a safe and efficient surgical method in treatment of compressive vertebrae fractures which do not react to the conventional method of treatment. This method, when HVC is applied, shows significantly less complications related to cement leakage.
