New White Paper: Sublaminar Bands vs. All-Screw Technique

Bordeaux, France-based Implanet has announced the publication of a White Paper that, as the company wrote in its September 5, 2017 news release, highlights the JAZZ System’s “safety and efficacy in the treatment of idiopathic scoliosis.”

Entitled “How to optimize axial correction without altering thoracic sagittal alignment in hybrid constructs with sublaminar bands: description of the ‘frame technique,’” the paper presents the results of clinical analyses based on 3D radiological reconstructions with EOS 3D Service. This results from an independent study conducted at Robert Debré Hospital (APHP, Paris Diderot) Orthopedic Pediatric Surgery department.

As the company wrote, “The study analyzed 3D radiological reconstructions of 60 patients treated with the ‘frame’ technique, using JAZZ Band and JAZZ Frame implants. The rigid frame facilitates posteromedial translation, resulting in comparable axial rotational correction as compared to the traditional ‘All-Screw’ technique, while preserving the unique advantage of sublaminar implants for restoration of sagittal balance.”

“Although, for many surgeons, pedicle screws represent the Gold Standard in treating idiopathic scoliosis, sublaminar bands should be considered as part of the therapeutic arsenal, as their beneficial action on the sagittal balance has been proven. Their excellent biomechanical properties enable considerable correction forces to be applied without running the risk of pulling out the concave screws”, says Professor Brice Ilharreborde, M.D., Ph.D., of Robert Debré Hospital, Paris Diderot University, France. “The frame technique combined with the use of JAZZ implants makes it possible to optimize axial correction while respecting the patient’s sagittal alignment”.

Ludovic Lastennet, CEO of Implanet, added, “This highly-anticipated study confirms that the use of JAZZ implants, combined with the frame technique, offers surgeons a safe and efficient alternative to traditional techniques. These results notably confirm the derotation capabilities of JAZZ implants associated with the JAZZ Frame. Henceforth, we have objective and irrefutable clinical evidence concerning the added value provided by JAZZ implants and the frame technique favoring their use.”

Professor Ilharreborde told OTW, “The frame technique using CoCr rods offers a solid and stable personalized construct for deformity reduction, and emphasize sagittal alignment restoration with JAZZ sublaminar bands.”

“The frame technique was able to provide excellent frontal correction rates, without impairing sagittal alignment. The postoperative thoracic flattening frequently reported with all-screw constructs was not observed, and apical axial correction averaged 43% although no direct derotation maneuver was applied.”
