Anatomical analysis of antebrachial cutaneous nerve distribution pattern and its clinical implications for sensory reconstruction.
This study aimed to reveal the distribution pattern of antebrachial cutaneous nerves and provide a morphological basis for sensory reconstruction during flap transplantation. Forearm specimens containing skin and subcutaneous fat were obtained from 24 upper extremities of 12 adult cadavers. Cutaneou...

The middle 1/3 of the medial and lateral forearm had the relatively dense total nerve branches.
