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.

Introduction: Paediatric gastrointestinal endoscopy (pGIE) has advanced significantly over the last decade, with increased diagnostic and therapeutic applications.
Objectives: This study examines the current state of pGIE in Spain, changes in the field over 5 years, and the involvement of paediatric gastroenterologists (pGEs).
Materials And Methods: A structured self-administered questionnaire was distributed by the Endoscopy Working Group of the Spanish Society of Paediatric Gastroenterology, Hepatology, and Nutrition (SEGHNP) through the REDCap platform.
Anatomical variations in 3D imaging: A case report of a dorsal metacarpal artery anomaly.

This report presents a novel anatomical variant of the second dorsal metacarpal artery (SDMA). In this unique case, the SDMA abnormally penetrates the second dorsal interosseous muscle (SDIM), dividing into two major branches. A deep dorsal branch of the SDMA (dbSDMA) is located within the SDIM and extends to the distal end of the metacarpal.
