ABSTRACT
RESUMEN La parálisis del nervio radial producida por lesiones a nivel del brazo es considerada una parálisis alta, y se caracteriza por presentar la muñeca y los dedos flexionados y el pulgar en aducción con imposibilidad para la extensión de los mismos (muñeca y dedos). Todos los autores coinciden en que, para la extensión de la muñeca, el músculo de elección a transferir es el pronador redondo para el segundo radial. Sin embargo, hay diversidad de criterios sobre la utilización del palmar mayor o del cubital anterior para el extensor común de los dedos, y del palmar menor para el extensor largo del pulgar. Se presentó el caso de un paciente de 31 años de edad, con antecedente de accidente de tránsito y diagnóstico de parálisis radial alta de 18 meses de evolución, en el que se decide tratamiento quirúrgico utilizando el músculo cubital anterior después de una rehabilitación exitosa, obteniéndose excelentes resultados (AU).
ABSTRACT The radial nerve paralysis produced by lesions at the level of the arm is considered a high paralysis, and is characterized by presenting the wrist and fingers flexed and the thumb in adduction with impossibility of extending them (wrist and fingers). All consulted authors agree that, for wrist extension, the elective muscle to transfer is the round pronator for the second radial. However, there are different criteria on the use of the palmar major or anterior ulnar for the common finger extender, and the palmar minor for the long thumb extender. We presented the case of a 31-year-old patient, with a history of traffic accident and diagnosis of 18-month high radial paralysis, in which surgical treatment using the anterior ulnar muscle after a successful rehabilitation was decided, obtaining excellent results (AU).

Background: Radial nerve originates from posterior cord of brachial plexus at axilla. It supplies extensor musclesof upper limb.Objectives: To know the variations in muscular branches of radial nerve in axilla and posterior compartment ofarm.Methods: Dissection was done on 44 upper limbs from embalmed cadavers and 6 upper limbs from embalmeddead fetuses in the Department of Anatomy, J J M Medical College, Davangere. Dissection of Radial nerve and itsbranches in the axilla and posterior compartment of the arm was carried out according to Cunningham’s manualof practical anatomy.Results: The site of origin of nerve to long head of tricep (N-LHT) was axilla in 48 specimens (96%) and lowertriangular space( LTS) in 2 specimens (4%). The site of origin of nerve to lateral head of tricep( N-LTHT) was radialgroove(RG) in 49 specimens (98%) and lower triangular space(LTS) in 1 specimens (2%). The site of origin ofnerve to medial head of tricep -ulnar collateral nerve(UCN) was axilla in 38 specimens (76%) and lower triangularspace(LTS) in 12 specimens (24%). The site of origin of nerve to medial head of tricep-nerve to anconeus(NA) wasradial groove(RG) in 49 specimens (98%) and lower triangular space(LTS) in 1 specimens (2%). The additionalbranches to long head of tricep(LHT) was found in 20 specimens (40%). The additional branches to lateral headof tricep( LTHT) was found in 10 specimens (20%). The additional branches to medial head of tricep(MHT) wasfound in 7 specimens (14%).Interpretation and Conclusion: The present study is important for Surgeons, Orthopedicians, and Neurophysiciansas it provides the knowledge of variations in muscular branches of radial nerve in axilla and posteriorcompartment of arm to prevent possible complications.
ABSTRACT
Background: Radial nerve is the continuation of the posterior cord of the brachial plexus in the Axilla. It is thenerve of extensor compartment of upper limb.Objectives: To know the course, and variations of radial nerve in the axilla, lower triangular space and posteriorcompartment of the armMethods : Dissection was done on 44 upper limbs from embalmed cadavers and 6 upper limbs from embalmeddead fetuses in the Department of Anatomy, J J M Medical College, Davangere. Dissection of Radial nerve and itsbranches in the axilla and posterior compartment of the arm was carried out according to Cunningham’s manualof practical anatomy.Results : In the present study, out of 50 specimens, Radial nerve(RN) originated from the posterior cord ofbrachial plexus at axilla, lies posterior to third part of axillary artery, descends behind the proximal part ofbrachial artery , passes through lower triangular space(LTS) and radial groove and accompanies the profundabrachii artery in 50 specimens(100%). 22 specimens (44%) showed high division of Radial nerve(RN) in to twodivisions at axilla and lower triangular space (LTS). The relation between two high divisions of Radial nerve(RND) was anterior & posterior or medial & lateral .In all cases (100%), either anterior or lateral divisioncontinues as radial nerve in to anterior compartment of arm.Interpretation &Conclusion :The present study is important for Surgeons, Orthopedicians, and Neurophysiciansas it provides the knowledge of course of radial nerve in axilla and posterior compartment of arm to preventpossible complications.
ABSTRACT
Traumatic peripheral neuropathy can occur following fracture, dislocation, forceful reduction or direct compression. During the emergency medical relief mission for earthquake victims in Pakistan, between 30th Oct and 14th Nov 2005, four patients presented with wrist drop and two others with foot drop, all with no underlying fracture or dislocation. All of them were attended by medical teams two to three days for the first time due to difficult rescue work and hard terrain. They were seen in field hospital
