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

Detaillierte Beschreibung
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
Zeitfenster: 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

Clinically Significant Neuropathic Pain at 6 Months - Numeric Rating Scale
Zeitfenster: 6 months
|
Numeric Rating Scale (NRS) is used to measure pain, where 0 is "no pain" and 10 is "worst pain imaginable"

Average Sensory Function with Semmes-Weinstein monofilament testing
Zeitfenster: 1, 3, 6, and 12 months
|
The Semmes-Weinstein monofilament test is a quick, non-invasive, and objective clinical exam used to evaluate nerve function by measuring skin sensitivity to light touch and pressure.

Average Sensory Function with Static 2-point discrimination
Zeitfenster: 1, 3, 6, and 12 months
|
Static 2-point discrimination (2PD) is a clinical test measuring the minimum distance at which a patient can perceive two simultaneous touch stimuli as distinct, rather than one, using a device like an aesthesiometer or disk-criminator.
