Smith & Nephew (NYSE:SNN, LSE: SN), announcef the launch of Q-FIX CURVED, Q-FIX MINI and SUTUREFIX CURVED All-Suture Anchor systems adding to its growing Sports Medicine portfolio. Designed for procedures where space is limited and the anatomy can be difficult to access, the new SUTUREFIX CURVED, Q-FIX CURVED and MINI delivery systems are designed to aid in optimal suture anchor placement during drilling and insertion.

The SUTUREFIX CURVED and Q-FIX CURVED systems improve access and trajectory when drilling bone tunnels. Both systems optimize the curved geometry of the drill guide while also maximizing drilling accuracy. 1 The incorporation of both visual and tactile cues simplifies drill guide orientation for the surgeon and helps to indicate drilling trajectory.

The Company also introduced its Q-FIX MINI All-Suture Anchor, which reduces the tunnel drill depth and implant length to 17.1mm, making it the shortest all-suture anchor in its class.2

Commenting on the new Q-FIX CURVED drilling system, Felix H. “Buddy” Savoie III, MD, Chairman of Orthopaedic Surgery and Chief of Sports Medicine at Tulane University School of Medicine said, “The new Q-FIX CURVED drilling system and Q-FIX MINI represent another advancement by Smith & Nephew in soft tissue fixation.  The curved drilling system improves access to the inferior glenoid while improving the trajectory of the drill bit, thereby reducing the risk of bicortical perforation. And the MINI anchor’s short drill depth improves patient safety, making it more useful in all applications, especially in small joint soft tissue fixation.”

“The unique tapered distal curve of the SUTUREFIX CURVED Drill Guide allows me to place these anchors anywhere that I would like along the acetabular rim,” said Dr. Marc J. Philippon of the Steadman Philippon Research Institute. “The active deployment of this all-suture anchor system greatly reduces displacement and the new curved guide has a better curvature and drilling trajectory than other curved systems on the market.”

“The Q-FIX MINI, Q-FIX CURVED and SUTUREFIX CURVED enable healthcare professionals to access challenging pathology like they have never been able to do before,” said Scott Schaffner, Senior Vice President Global Marketing, Smith & Nephew. “These new products highly complement our Sports Medicine range and we’re proud to offer them as part of our growing portfolio.”

Unlike other all-suture anchors that require the suture strands to be pulled back against the cortical bone in order to deploy them, Smith & Nephew’s Q-FIX and SUTUREFIX All-Suture Anchor platform uses active deployment3, which eliminates manual tensioning and makes deployment more reliable4, ultimately resulting in improved biomechanical performance among all-suture anchors.5,6,7
