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
調査の概要
詳細な説明
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
時間枠: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
