Abstract:
OBJECTIVE: To evaluate the curative effect and clinical significance of bone cement on coagulation functions during percutaneous vertebroplasty in patients with osteoporotic spinal compression fractures.METHODS: A total of 24 patients, comprising 18 females and 6 males, aged 69 years averagely (range 48-83 years), with 44 osteoporotic vertebral compression fractures underwent percutaneous vertebroplasty in Department of Spinal Surgery, Third Hospital of Hebei Medical University between December 2006 and December 2007. The fracture segment was within T_5-L_3 (20 thoracic vertebrae and 24 lumbar vertebrae). Under the guidance of C-arm fluoroscopy, bone marrow biopsy needle was inserted percutaneously via transpedicular way into the fractured vertebrae. Polymethylmethacrylate (PMMA, bone cement) was injected into the fractured vertebrae. The relative parameters were observed in all patients 10 minutes before, 10 minutes, 30 minutes, 1 hour, 2 hours and 3 hours after bone cement implantation, including prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (FIB), plasma protamine paracoagulation test (3P test), and D-dipolymer (D-D). RESULTS: PT was decreased, and FIB, 3P test, D-D were increased 10 minutes after bone cement implantation in percutaneous vertebroplasty peaked at 1 hour and gradually decreased afterward; moreover, there were significant difference between bone cement preimplantation and 10 minutes, 30 minutes, 1 hour, 2 hours and 3 hours after bone cement implantation (P < 0.05), but no difference was observed in APTT and TT (P > 0.05). The influence of bone cement on the parameters was vanished in 3 hours after bone cement implantation, and all indexes were similar to pre-implantation (P > 0.05).CONCLUSION: Bone cement implantation causes temporal hypercoagulabale state in percutaneous vertebroplasty. It is important to monitor blood clotting state in 3 hours after bone cement implantation in order to avoid thrombus disease.
