Treace Medical Presents Positive Clinical Data for 3D Bunion Correction Technologies at ACFAS 2026
核心洞察
Treace Medical Concepts presented interim data from three clinical studies at the ACFAS 2026 conference, demonstrating positive outcomes for their bunion (搜索) correction technologies.
The ALIGN3D study showed 8.4% radiographic recurrence rates at 48 months and 95% lower recurrence risk in patients with proper 3D correction.
The company unveiled six new product innovations including SpeedTMT (搜索) rapid compression implants and Lightning instrumentation system for enhanced surgical precision.
Treace Medical Concepts showcased compelling clinical evidence and next-generation surgical technologies for bunion (搜索) correction at the American College of Foot and Ankle Surgeons (ACFAS) Annual Scientific Conference in Las Vegas from February 24-26, 2026. The medical technology company presented interim data from three major clinical studies while unveiling six innovative product platforms designed to advance 3D bunion correction procedures.
Clinical Study Results Demonstrate Sustained Outcomes
The ALIGN3D clinical study, a prospective five-year multicenter trial, presented interim analysis of 146 of 173 patients with at least four years of follow-up following the Lapiplasty (搜索) 3D Bunion (搜索) Correction procedure. The data revealed low radiographic recurrence rates of 8.4% (12 of 143 patients) at 48 months using hallux valgus (搜索) angle greater than 15 degrees as the measurement criterion.
"We are proud to showcase our latest clinical data and innovations at ACFAS, including our next-generation Lapiplasty (搜索) instrumentation and fixation technology platforms," said John T. Treace, CEO, Founder and Chairman of Treace Medical Concepts.
A particularly significant finding showed that patients with corrected tibial sesamoid position of 3 or less at 6 weeks post-operation had a 95% lower risk of recurrence at 48 months. This tibial sesamoid position serves as an indicator of proper 3-plane correction, highlighting the importance of comprehensive deformity correction.
The MTA3D clinical study evaluated combined Adductoplasty (搜索) and Lapiplasty (搜索) procedures for patients requiring both metatarsus adductus (搜索) and hallux valgus (搜索) correction. Interim analysis of 33 patients with one-year follow-up and 14 patients with two-year follow-up demonstrated clinically significant improvement and maintenance of radiographic measures through 24 months, along with significant reduction in pain scores using VAS, MOxFQ, and PROMIS assessments.
Rapid Recovery Times Across Procedures
All three clinical studies demonstrated notably rapid return to weight-bearing activities. The ALIGN3D study showed patients returned to weight-bearing in a walking boot at an average of 8.4 days, while the MTA3D study patients achieved this milestone at 7.9 days on average.
The SpeedMTP (搜索) retrospective study, analyzing 43 patients undergoing great toe joint fusion with a mean follow-up of 6.4 months, showed the most rapid recovery with patients returning to weight-bearing at an average of 3.7 days. This study achieved full radiographic union in all patients at 6 months follow-up.
Next-Generation Technology Portfolio
Treace introduced six new technological innovations designed to enhance surgical precision and efficiency:
The SpeedTMT (搜索) Rapid Compression Implant represents the latest advancement in Lapiplasty (搜索) SpeedPlate fixation, utilizing hybrid fixation technology that combines SpeedPlate dynamic fixation with FastPitch locking screws. This system provides robust fixation while maintaining an ultra-low profile, with full commercialization expected in the second half of 2026.
The Lapiplasty (搜索) Lightning System serves as the next-generation instrumentation platform, designed to provide surgeons with greater accuracy and control of 3D correction while reducing surgical steps for faster procedures. Full commercialization is anticipated in late 2026.
Minimally Invasive Options Expand Access
The company's minimally invasive portfolio includes two distinct approaches. The Nanoplasty (搜索) procedure utilizes a single 1.5cm hidden incision on the side of the foot, featuring guided saw cuts that eliminate the burr learning curve typically associated with minimally invasive surgery.
The Percuplasty (搜索) procedure takes minimally invasive surgery further with 0.5cm percutaneous incisions, incorporating self-drilling screw implants and instrumentation that enables precise 3D correction and accurate implant placement.
Comprehensive Study Design and Methodology
The ALIGN3D study enrolled 173 patients aged 14 to 58 years across 7 clinical sites in the United States with 13 participating surgeons. The study's primary effectiveness endpoint focuses on radiographic recurrence of hallux valgus (搜索) deformity, with secondary endpoints including three-dimensional radiographic alignment changes, clinical healing, weight-bearing timelines, pain assessment, quality of life measures, and range of motion evaluation.
The MTA3D study will treat up to 80 patients aged 14 years and older at up to 13 clinical sites, with patients followed for 2 years following combined procedures. The study's primary endpoint measures maintenance of radiographic correction for both hallux valgus (搜索) and metatarsus adductus (搜索) deformities.
Market Impact and Clinical Significance
Treace estimates that bunions affect approximately 67 million Americans, with 1.1 million representing annual surgical candidates. The company's comprehensive portfolio now includes the flagship Lapiplasty (搜索) system alongside Adductoplasty (搜索), Nanoplasty (搜索), Percuplasty (搜索), SpeedMTP (搜索), and IntelliGuide (搜索) patient-specific instrumentation technologies.
The IntelliGuide (搜索) PSI platform delivers personalized 3D-printed cut guides for both Lapiplasty (搜索) and Adductoplasty (搜索) procedures, featuring intelligent pre-operative 3D planning and titanium 3D-printed guides with integrated 3D correction for streamlined surgical workflow.
