This anatomical study of 40 upper limbs from cadavers investigated the branching pattern of the anterior interosseous nerve in its distal part using the operating microscope. An articular branch to the wrist joint and/or the distal radioulnar joint was only found in seven of the 40 specimens and was always a small terminal continuation of the anterior interosseous nerve after the nerve had passed through the pronator quadratus and innervated it. Therefore, we do not recommend division of the anterior interosseous nerve from the dorsal approach through the interosseous membrane before it gives off its muscular branches to the pronator quadratus. This risks damage of the innervation of this muscle of importance for initiation of hand pronation.

An ulnar nerve (UN) palsy is devastating for hand function, resulting in an intrinsic minus position or claw hand with a loss of pinch grip. Distal nerve transfers facilitate faster reinnervation of hand intrinsic muscles in cases of proximal ulnar nerve lesions. The traditional anterior interosseous nerve (AIN) to UN motor transfer is commonly used, however, this still leads to long reinnervation times for the distal intrinsic muscles, important for the thumb to index pinch grip.

Introduction: During 280 years of studies of the anatomy of the distal tibiofibular articulation, there have arisen many unclear issues regarding the description of individual structures and their terminology. These historical inaccuracies were subsequently reflected in the clinical practice.
Materials And Methods: A literature search of original publications and historical sources was performed.

Objectives: Proximal median nerve (PMN) neuropathies are caused by lesions proximal to the carpal tunnel, which include the forearm, elbow, upper arm, and brachial plexus. Differentiating between carpal tunnel syndrome and PMN neuropathies is important to guide management and is based on clinical, electrodiagnostic (EDX), and ultrasound (US) findings. This study describes the clinical, EDX, and US features in 62 patients with PMNs.

The human upper limb has undergone various evolutionary myologic changes, accompanied by corresponding modifications in the anatomical course of neurovascular structures. In this study, we aimed to elucidate the emergence of the accessory head of the flexor pollicis longus (AHFPL) muscle as a beneficial biomechanical evolutionary development and its topographical relationship with adjacent neurovascular structures. In this pursuit to understand this phenomenon, dissections were conducted on sixty-two upper limbs from thirty-one cadavers.
