AbstractThe median nerve is formed in the axilla by fusion of the two roots from the lateral and medial cords. The present case report describes an anomalous presentation of double formation of median nerve and its relation with axillary and brachial arteries. The median nerve was formed in two stages at different levels, first in the axilla and then in the upper arm by receiving double contribution from the lateral root of the lateral cord, which fuse with the medial root of the medial cord to form the median nerve. The formation took place medial to the axillary artery in the axilla and antero-medial to the brachial artery in the arm. Such anatomical variations and their relation with the arteries are important for the surgeons and anesthesiologists and of great academic interest to the anatomists.

The authors describe a case of carpal tunnel syndrome due to Madelung’s deformity. They discuss the pathophysiological causes of median nerve entrapment to explain the compression which occurs in this disease and its clinical implications. They take also into consideration the surgical approach to the carpal tunnel in this particular condition.

Bulgarian Population

High division of the median nerve proximal to the carpal tunnel, also known as a bifid median nerve, is a rare anatomical variant with an incidence between 1 and 3%. In order to study the incidence of this anatomical variation in the Bulgarian population, we examined the upper limbs of 51 formol-carbol fixed human cadavers and also 154 upper limbs undergoing carpal tunnel decompression. We detected one case of bifid median nerve during anatomical dissections and two cases in patients with carpal tunnel syndrome. In one of the clinical cases, the anatomical variation was detected preoperatively by MRI. We discuss different variations of this nerve and emphasize their potential clinical implications.

Anatomical Area

La fosa infratemporal es un área anatómica clínicamente importante para la administración de agentes anestésicos locales en odontología y cirugía maxilofacial. Fueron estudiadas variaciones en la anatomía del nervio alveolar inferior y la arteria maxilar en la disección infratemporal. Durante la disección rutinaria de la cabeza en el cadáver de un varón adulto, fue observada una variación excepcional en el origen del nervio alveolar inferior y su relación con las estructuras circundantes. El nervio alveolar inferior se originaba en el nervio mandibular por dos raíces y la primera parte de la arteria maxilar estaba incorporada entre ambas. El origen embriológico de esta variación y sus implicaciones clínicas es debatido. Dado que la arteria maxilar transcurría entre las dos raíces del nervio alveolar inferior, y el nervio estaba fijado entre el foramen oval y el foramen mandibular, el atrapamiento vásculo-nervioso pudo causar entume-cimiento o dolor de cabeza e interferir con la inyección de anestésicos locales en la fosa infratemporal.  Variaciones anatómicas en esta región deben ser tenidas en cuenta, especialmente en casos de tratamiento fallido de neuralgia del trigémino. Infratemporal fossa is clinically important anatomical area for the delivery of local anesthetic agents in dentistry and maxillofacial surgery. Variations in the anatomy of the inferior alveolar nerve and maxillary artery were studied in infratemporal dissection. During routine dissection of the head in an adult male cadaver an unusual variation in the origin of the inferior alveolar nerve and its relationship with the surrounding structures was observed. The inferior alveolar nerve originated from the mandibular nerve by two roots and the first part of the maxillary artery was incorporated between them. An embryologic origin of this variation and its clinical implications is discussed. Because the maxillary artery runs between the two roots of the inferior alveolar nerve, and the nerve was fixed between the foramen ovale and mandibular foramen, neurovascular entrapment may cause pain numbness or headache and may interfere with the injection of local anesthetics into the infratemporal fossa. Anatomical variations in this region should be kept in mind, particularly in cases of failed treatment of trigeminal neuralgia.

Introduction: This paper reports anatomical study of nature, incidence, innervation and clinical implications of Flexor Pollicis Brevis muscle (FPB). Material and Methods: The anatomical dissection of 60 limbs from 30 cadavers were performed in the Department of Anatomy of Medical School of Catholic University of São Paulo. Results: The superficial head of FPB has been innervated by the median nerve in 70% and in 30% it had double innervation. The deep head of FPB were absent in 14%, in 65%, occurred a double innervation. In 17.5% by deep branch of ulnar nerve and in 3.6% by recurrent branch of median nerve. Conclusion: The pattern of innervation more frequent in relationship to the flexor pollicis brevis muscle and should be considered as a normal pattern is that superficial head receives innervation of branches of median nerve and the deep head receives innervation of ulnar and median nerve.

In occlusive vascular brain diseases, the structure of the circle of Willis is of immense importance. A high percentage of variations have been reported in the arteries forming circle of Willis. These have profound clinical implications. With advances in interventional radiological procedures, the interventional radiologists and neurosurgeons need to have thorough knowledge of these variations. This article will help readers understand the significance of anatomical variations and their clinical effects.
