Published: July 2024

The Kaplan anastomosis is a rare communication originally described between the superficial and dorsal branches of the ulnar nerve, distal to the ulnar tunnel, and in strict relation with the pisiform bone. It reveals, by its particular location, a formation of high clinical-surgical expressiveness. In this paper, we describe a Kaplan-type communication from a left upper limb with an unusual loop conformation between branches of the ulnar nerve in the pisiform bone.

This study aimed to compare the fascicular anatomy of upper limb nerves visualized using in situ high-resolution ultrasound (HRUS) with ex vivo imaging modalities, namely, magnetic resonance microscopy (MRM), histological cross-sections (HCS), and optical projection tomography (OPT). The median, ulnar, and superficial branch of radial nerve (n = 41) were visualized in 14 cadaveric upper limbs using 22-MHz HRUS. Subsequently, the nerves were excised, imaged with different microscopic techniques, and their morphometric properties were compared.

Background And Objectives: The unifying articular theory suggests that intraneural ganglion cysts in the cubital tunnel arise from the elbow joint and are connected to the ulnar nerve through an articular branch. This study aimed to report our clinical experience with these cysts and our surgical findings and outcomes.

Methods: We retrospectively analyzed 13 patients who underwent surgery for cubital tunnel syndrome caused by an intraneural ganglion cyst of the ulnar nerve.

Arterial variations in the upper limb are of significant clinical importance, especially in procedures such as venepunctures, coronary artery bypass grafts, trauma reconstructive surgeries, brachial plexus nerve blocks, and breast reconstructions. This report presents previously undocumented arterial variations in the upper limbs in a 95-year-old female cadaveric donor. We observed bilateral superficial ulnar arteries originating at the cubital fossa, deviating from the previously reported origin at the proximal brachial artery.

A 44-year-old male patient experienced persistent radiating pain from the elbow to the hand following herpes zoster vesicular eruptions three months earlier. His examination met the Budapest Clinical Criteria for Complex Regional Pain Syndrome (CRPS), revealing sensory, motor, vasomotor, and sudomotor signs and symptoms. Despite conservative treatments, the pain persisted.

Background: Understanding peripheral ulnar nerve anatomy is necessary to refine surgical treatment of ulnar nerve injuries. This study topographically mapped the ulnar nerve and its distal branch points from a well-defined surgical landmark and assessed for variations in interfascicular motor arrangement and branch size.

Methods: Fifty-four cadaveric upper extremities were dissected to expose the distal ulnar nerve and its branches (dorsal cutaneous (DCB), volar sensory (VSB), and motor branches).
