Anatomical variations of the innervated radial artery superficial palmar branch flap: A series of 28 clinical cases.

ABSTRACT:

Background

The innervated radial artery superficial palmar branch (iRASP) flap was designed to provide consistent innervation by the palmar cutaneous branch of the median nerve (PCMN) to a glabrous skin flap. The iRASP flap is used to achieve coverage of diverse volar defects of digits. However, unexpected anatomical variations can affect flap survival and outcomes.

Methods

Cases in which patients received iRASP flaps since April 1, 2014 were retrospectively investigated by reviewing the operation notes and intraoperative photographs. The injury type, flap dimensions, arterial and neural anatomy, secondary procedures, and complications were evaluated.

Results

Twenty-eight cases were reviewed, and no flap failures were observed. The observed anatomical variations were
