Evaluating Avive+ Soft Tissue Matrix for Prevention of Superficial Radial Nerve Morbidity Following Radial Forearm Free Flap Harvest
A Randomized Controlled Pilot Study Evaluating Avive+ Soft Tissue Matrix for Prevention of Superficial Radial Nerve Morbidity Following Radial Forearm Free Flap Harvest
연구 개요
상세 설명
Radial forearm free flap (RFFF) harvest is associated with significant donor-site morbidity, including neuropathic pain, hypoesthesia, and functional impairment related to superficial radial nerve irritation and postoperative scar formation. Current donor-site management focuses on wound closure and healing but does not directly address nerve protection.
Avive+ Soft Tissue Matrix is a human-derived biologic material designed for soft tissue reinforcement and protection. Its use as a barrier over surgically manipulated nerves is biologically plausible but has not been studied in this clinical context.
This study is a prospective, randomized controlled pilot trial designed to evaluate the feasibility, safety, and preliminary efficacy of Avive+ placement over the superficial radial nerve during RFFF harvest. Subjects will be randomized to standard closure versus Avive+ placement plus standard closure. Outcomes will focus on neuropathic pain, sensory function, and wound complications.

Clinically Significant Neuropathic Pain at 6 Months - DN4 score
기간: 6 months
|
A DN4 questionnaire score of 4 or higher out of 10 indicates a high probability of neuropathic pain.
This validated tool, which can be viewed in this DN4 Questionnaire consists of seven patient-interview questions and three clinician-examination items, with a total score distinguishing neuropathic from non-neuropathic pain.
A score greater than or equal to 4 is considered positive for neuropathic pain
