The design and structure of the palmar vascular arches and their variations constitute some of the most intriguing and difficult areas of anatomy. Additionally, cardiac revascularisation is now being accomplished using radial artery harvesting, which necessitates collateral circulation in the hand through the palmar arches. In this case report, we outline a unique pattern of the superficial palmar arch (SPA) and deep palmar arch (DPA) in terms of their formation and branching pattern. The first and second dorsal metacarpal arteries (DMAs) emerged from the radial artery. Both the first and second DMAs participate in the formation of SPA and DPA, respectively. Additionally, there was an anastomosis between the third common digital artery (CDA) and the proper digital artery, which has not yet been documented in any literature, and the third CDA was derived from the DPA. Understanding the variations in the arteries of the hand is becoming increasingly crucial for surgeons due to recent advancements in microsurgical techniques for vascular repair.

Parkinson's disease (PD) is a progressive neurodegenerative disorder affecting around 10 million people worldwide. It is primarily associated with the loss of dopaminergic neurons in the substantia nigra pars compacta, though the exact mechanism is unclear. PD is characterized by resting tremor, muscular rigidity, bradykinesia, and postural instability.

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.

Purpose: The branching pattern of the deep motor branch of the ulnar nerve (DBUN) in the hand is complex. The anatomy of the motor branch innervating the fourth lumbrical (4L), where paralysis results in a claw hand deformity after ulnar nerve injury, is not well defined. This cadaver study focused on mapping and defining anatomical landmarks in relation to the motor branch to the 4L.

Objectives: Glomangiomas are benign vascular malformations that exist within the spectrum of glomuvenous malformations which consist of varying amounts of glomus cells, vascular spaces, and smooth muscle. Glomangiomas are often treated due to associated pain, particularly when located on pressure areas such as the back or extensor surfaces, which can cause difficulty with certain activities and occupational functions. Histologically glomangiomas consist of prominent dilated vascular spaces lined by glomus cells typically situated in the deep-dermis to subcutaneous fat which limits treatment to modalities capable of reaching the depth of the tumor including excision, sclerotherapy, and laser therapy.
