Event or Problem Description
A patient underwent a procedure over dorsal radial superficial nerve branches and axoguard ha+ nerve protector was implanted.The patient experienced incision site erythema and wound dehiscence.On (b)(6) 2025, the patient underwent surgery for removal of chromic gut sutures placed during the previous surgery due to a reaction, with neurolysis/neuroma, ha+ placed to protect the nerves.On an unspecified date, at the first post-op appointment, the patient exhibited a small area of redness near the incision.The incision then dehisced and progressed to an open wound.On (b)(6) 2026, the patient was taken back to the operating room for surgical exploration, irrigation and debridement (i&d), and explant of the axoguard ha+.Cultures/pathology were obtained, but results have not been shared with axogen at this time.Further treatment information, surgical technique, and event outcome are unknown.The surgeon reported causality as not related, stated that the patient had a previous reaction to foreign material, various comorbidities, and several surgeries in this same area.Axogen reported causality as unassessable due to the absence of cultures/pathology, multiple plausible alternative explanations (including patient/site-related factors), and insufficient evidence to determine whether the device contributed to the reported wound dehiscence and erythema.Lot history review confirmed that the product lot met all specifications, with no quality issues identified, and this adverse event appears to be isolated with no similar complaints reported for the lot.
