Six Month Follow-Up Suggests XPED Pedicle Screw May Outperform “Standard Pedicle Screws”

“The VAS and ODI scores obtained with the XPED were significantly better than the control group consisting of patients treated with standard screws.”

In short

“Six month follow- up of patients after lumbar fusion surgery using a new expandable pedicle screw system; a prospective study” was presented as an e-poster at last weekend’s Scoliosis research Society Meeting, which took place during the 19th International Meeting on Advanced Spine Techniques in Istanbul, Turkey.

Background

Israeli company Expanding Orthopedics Inc., developed its XPED pedicle screw system with the express goal of developing a pedicle screw system with enhanced anchoring capability in compromised bone.

Over a period of 12 months clinical information was collected 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.

Clinician comments

Dr. Ory Keynan, Head of Service for Degenerative and Age-related Spinal Disorders at the Sourasky Medical Center, Tel-Aviv, Israel, explained that “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.”

Dr. 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.” Dr. Keynan added that “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.”

Company comments

Mr. Ofer Bokobza, CEO of Expanding Orthopedics, said that “we are thrilled that a very well respected spine research society as the Scoliosis Research Society, has accepted to present the clinical results of our XPED Expanding Pedicle Screw System for the first time at an international spine congress.” Mr. Bokobza confirmed that “a growing number of surgeons in Europe and Israel are starting to adopt the XPED system and believe that these positive clinical results will encourage the medical community to adopt the XPED System as the standard of care for specific indications and pathologies.”
