AIM: The aim of this article was to study the results of two different types of percutaneous vertebroplasty (PV) and kyphoplasty (KPs) to osteoporotic vertebral fractures (OVF).
METHODS: It was prospectively analyzed a series of 47 PVs from January 2003 to February 2008, and a consecutive series 30 KPs from March 2008 to January 2010, performed for patients with painful OVFs. Twenty-five PVs were performed using the frontal-opening cannula (FOC) and 22 using the new side-opening cannula (SOC), randomly distributed in the PV group.
RESULTS: The incidence of cement extrusion was 16.7% with KP, comparing with PV, it was 27.3% using the SOC (P<0.05) and 68,0% with the FOC (P<0.05), but comparing SOC with FOC, the cement extrusion was significantly lower using the SOC (P<0.05), all asymptomatic. The pain control was similar for all groups (P<0.05), with good improvement of pain in most of the patients, and there were no clinical relevant complications.
CONCLUSION: The cement leakage was significantly reduced with the KP (16.7%) and the SOC (27.3%) for PV, in comparison with the FOC (68.0%). The cement extrusion was slightly lower with KP, but not a significant difference, comparing with SOC, increasing the safety of the procedure using both the KP and this new SOC.
