Eficacia de la transferencia de dos bandas miotendinosa del flexor carpis ulnaris en la centralización de la muñeca y extensión de dedos propuesta por Torres en pacientes con lesión intermedia y baja del nervio radial en el servicio de Traumatología y Ortopedia del Hospital Antonio Patricio de Alcalá, período febrero 2020 - enero 2021.

Abstract

Radial nerve injuries are usually diagnosed by physical examination, although electrodiagnostic and radiological studies can help to identify the exact location of the injury and the degree of damage, thereby enabling a more accurate treatment protocol to be decided upon. follow, continue. High injuries occur above the innervation of the triceps brachii, intermediate injuries occur below the innervation of the triceps and above the elbow, and low injuries occur below the elbow and between the latter, occasionally, there is injury to the posterior interosseous nerve. The purpose of this work is to design a technique that allows keeping the wrist centered and reconstructing the extension function of the fingers and keeping the wrist centered. For this purpose, we selected a technique based on the flexor carpis ulnaris divided into two bands that will serve to centralize the wrist and extend the fingers. The duration of the study ranged from February 2020 to January 2021. 3 male patients from the consultation of the Traumatology and Orthopedics service of the Antonio Patricio de Alcalá University Hospital, Cumaná, were taken to the operating room during the period from February 2020 to January 2021 with neurotmesis of the intermediate and low radial and were clinically evaluated to verify degrees of centralization of the wrist and extension of the fingers. All the patients operated on in this study presented preoperatively without finger extension and wrist centered at 0 ° as expected due to the intermediate and low radial nerve injury. During the postoperative evaluation, it was possible to verify the extension of the fingers to 0 ° starting from complete flexion of the proximal interphalangeal joint 110 ° and 0 ° starting from the maximum flexion of the distal interphalangeal joint 90 ° and centralization of the wrist at rest and activates plus or minus up to 5 °. The two-band technique of the flexor carpis ulnaris was effective for the extension of the fingers and centralization of the wrist, being a reproducible technique that achieves functional reconstruction of the extension of the fingers and centralization of the wrist.
