MTA3D^™ Clinical Study Poster¹

“Interim 1-Year Analysis of a Prospective Multicenter Study Assessing Radiographic and Patient-Reported Outcomes Following Combined Metatarsus Adductus and Hallux Valgus Correction through 3rd, 2nd, and 1st Tarsometatarsal Arthrodesis with Early Weightbearing” presented by Paul Dayton, DPM (Foot and Ankle Center of Iowa, Ankeny, IA). The featured interim data from the prospective, five-year, multicenter MTA3D^™ clinical study of the patients undergoing both the Adductoplasty® and Lapiplasty® procedures included interim analysis of 18 of 38 patients treated with at least one year follow-up. The data showed:

• Early return to protected weightbearing in average of 7.5 days;
• Clinically significant improvement relative to baseline in radiographic measures of both midfoot (metatarsus adductus) and 3D bunion deformity correction at 12 months; and
• Clinically significant reduction in pain and patient-reported scores (MOxFQ and PROMIS) at 12 months.
