THE IFU ADEQUATELY PROVIDES INSTRUCTIONS FOR IMPLANTATION, PRECAUTIONS, AND WARNINGS FOR THE PROPER USE AND HANDLING OF THE DEVICE. POLYNOVO COULD NOT CONFIRM A DETERIORATION OR CHANGE IN THE CHARACTERISTICS OR PERFORMANCE, OR INACCURACIES IN THE LABELLING OR INSTRUCTION FOR THE REPORTED CASE. THE RATE OF THE REPORTED ISSUE TO POLYNOVO IS CONSIDERED LOW AND ACCEPTABLE. THE CLINICAL BENEFITS CONTINUE TO OUTWEIGH THE POTENTIAL RISKS ASSOCIATED WITH THIS HAZARD/USE OF THE DEVICE.

    A PROSPECTIVE COHORT STUDY WAS CONDUCTED AT THE VICTORIAN ADULT BURNS SERVICE, A 19-YEAR-OLD MALE PATIENT WHO HAD BTM (DEVICE SIZE, LOT NUMBER NOT SPECIFIED) IMPLANTED ON (B)(6) 2024 TO 3X HEALED WOUNDS ON THE NECK, LEFT AXILLA AND RIGHT AXILLA FROM AN ACUTE BURN (CLOTHES CAUGHT FIRE WELDING). THE WOUND SIZE WAS 30% TBSA. BTM WAS APPLIED TO 140CM2 ON THE NECK. AT 3 MONTHS, RESURFACED AREA WAS 31.5CM2; AT 6 MONTHS WAS 30CM2 (78.57% OVERALL CONTRACTION). BTM WAS APPLIED TO 153CM2 ON THE RIGHT AXILLA. AT 3 MONTHS, RESURFACED AREA WAS 40.5CM2; AT 6 MONTHS WAS 36CM2 (76.57% OVERALL CONTRACTION). BTM WAS APPLIED TO 40.5CM2 ON THE LEFT AXILLA. AT 3 MONTHS, RESURFACED AREA WAS 24.25CM2; AT 6 MONTHS WAS 14CM2 (81.82% OVERALL CONTRACTION). NO ADVERSE OUTCOMES SUCH AS BTM INFECTION OR GRAFT BREAKDOWN WERE REPORTED. THE STUDY WAS CONCLUDED AS LONG-TERM EFFICACY OF BTM FOR CONTRACTURE RELEASE WAS NOT DEMONSTRATED WITHIN THIS COHORT. WHILE BTM FACILITATES SAFE WOUND BED PREPARATION WITH RELIABLE GRAFT UPTAKE, SUSTAINED CONTRACTURE RELEASE WAS LIMITED IN THIS COHORT.
