Ory Keynan, head of Service for Degenerative and Age-related Spinal Disorders at the Sourasky Medical Center, Tel-Aviv, Israel, presented six months follow-up results of patients treated with the XPED Expanding Pedicle Screw System (Expanding Orthopedics) at the Scoliosis Research Society 19th International Meeting on Advanced Spine Techniques (IMAST) in Istanbul, Turkey (18-21 July 2012).
“Enhanced fixation of spinal implants is crucial to improve spine fusion success rates, particularly in revision surgeries, bone pathologies with compromised bone quality and in elderly patients,” said Keynan. “During the last 12 months, we have collected clinical information from 10 patients. In all cases successful implantation and deployment of the expandable section was achieved and no implant-related complications were observed. At 6 months follow-up, improvement was observed in all outcome measures.”
Keynan noted that “these positive results were confirmed at the 12 months follow-up visit: VAS improving by 60%, ODI by 32% and SF36 by 69%. The VAS and ODI scores obtained with the XPED were significantly better than the control group consisting of patients treated with standard screws.”
“The results suggest that immediate stability obtained with the XPED at the fusion site may provide early pain reduction with improved clinical outcomes when compared to standard pedicle screws,” said Keynan.
