Although anatomical variations in the arterial pattern of the hand have been the subject of many studies, information on the diameter of the superficial palmar arch contributing vessels and its branches are rarely found in the literature. The objective of the current study was to evaluate these arterial variations, with special attention to the diameter of the superficial palmar arch contributing vessels and its major branches. Forty-six hands from male embalmed human cadavers were evaluated, 21 right hands and 25 left hands. Complete arches were present in 43% on the right and in 52% on the left. Arches were completed by the median artery in two cases. Variations were more common at the radial side of the arch and on left hands. Comparison of vessel diameters revealed the radial artery to be significantly larger than the ulnar artery but the ulnar artery to be larger than the superficial branch of the radial artery. The diameters of the common digital arteries were not different with regard to complete or incomplete arches, or with regard to the presence of the median artery.

Article Synopsis
- The study examines the superficial palmar branch of the radial artery (SUPBRA) to improve techniques for reconstructing palmar skin, focusing on its anatomy and harvesting methods.
- Researchers dissected 19 male hand specimens to gather detailed anatomical data, including dimensions and positions of key structures related to SUPBRA, analyzing how best to utilize this flap in reconstruction efforts.
- Results indicated that the SUPBRA has adequate dimensions for viability in surgical applications, with specific measurements and the identification of critical vascular contributions that ensure successful use in cases of hand injury.

Objective: This study explored the surgical technique and clinical application of the dorsal metacarpal cutaneous branch flap of the radial digital artery of the index finger.
Methods: Through the anatomical dissection of 10 hand specimens, we examined the origin and characteristics of the artery and its branches towards the hand dorsum. Furthermore, the soft tissue defects of the index finger in 12 patients admitted to our hospital between 2017 and 2021 were surgically repaired using the dorsal metacarpal cutaneous branch flap of the radial digital artery of the index finger.

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.

Introduction: Tendon injuries of the hand present a diverse spectrum of challenges in emergency medicine, ranging from minor strains to catastrophic ruptures. The superficial anatomy of hand tendons predisposes them to various mechanisms of injury, leading to complex medical scenarios. Here, we present a unique case of flexor tendon exposure secondary to abscess formation and spontaneous rupture, emphasizing the importance of prompt recognition and management of such injuries in the emergency department.

Article Synopsis
- The median artery usually disappears after two months of fetal development but can persist into adulthood, sometimes associated with variations like a bifid median nerve.
- A cadaver study revealed a unique case with bilateral persistent median arteries (PMA) and a bifid median nerve, as well as an unusual origin and path for the palmar cutaneous branch of the median nerve (PCBMN).
- Dissection of a 45-year-old male cadaver showed that the PMA arose from the ulnar artery, leading to differing branching patterns in the hands, and highlighted the importance of recognizing these variations for understanding carpal tunnel syndrome and surgical risks.
