Introduction And Importance: True ulnar artery aneurysms are a rare entity, with existing literature suggesting that most of these aneurysms are due to trauma. This case report sheds light on a true ulnar artery aneurysm that was deemed to be idiopathic.
Case Presentation: A 49-year-old lady presented with numbness in the medial 3 fingers of the left hand, tenderness over the medial forearm, and a palpable ulnar artery pulse. There was no history of trauma. An arterial ultrasound, MRI of the forearm, and upper limb angiography confirmed the diagnosis of ulnar artery aneurysm. Surgical repair of the aneurysm was done with excellent immediate post-operative and follow up results.
Clinical Discussion: Trauma is the most common cause for the development of ulnar artery aneurysms. In this case however, after detailed history taking, physical examination, and thorough investigations, the cause of the patient's aneurysm was deemed to be idiopathic. Treatment of ulnar aneurysms are not well established due to the rarity of the disease. A surgical approach however may be considered depending on the location of the aneurysm along with the patient's symptoms.
Conclusion: A high index of suspicion, thorough history, physical examination, and appropriate investigations are required to diagnose ulnar artery aneurysms. Surgical intervention is indicated to relieve symptoms of nerve compression and prevent limb threatening ischemia. Regular post-operative follow up is essential to detect potential graft dysfunction and to ensure a good outcome.

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.

We present a case of arterial bypass for extensive stenosis of the ulnar artery and superficial palmar arch. The ulnar artery and the superficial palmar arch were bypassed using the great saphenous vein. Postoperatively, blood flow to the affected fingers gradually improved and the pain disappeared.

Peripheral nerve neuromas may present significant therapeutic challenges especially when neuromas in continuity are scar-tethered to adjacent vital structures. We report a case of a patient who presented with delayed neurotmesis of median and ulnar nerves in the arm while extensive scarring of the median nerve was found in close proximity to the repaired brachial artery. For the surgical restoration of the continuity of the median nerve, the scarred segment was left in situ to avoid reinjury of the brachial artery and a "fly-over" nerve grafting technique with sural nerve autografts was employed.

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.

Introduction: Giant cell tumor (GCT) of the bone, although benign, poses significant challenges due to its locally aggressive nature and high recurrence rates post-surgical intervention. Among skeletal GCTs, those affecting the distal radius present unique difficulties, especially when fungating masses encase vital structures such as blood vessels.
Case Report: We present a case of a 28-year-old male with a recurring GCT of the distal radius, where limb-preserving surgery was successfully performed despite encasement of the radial artery.
