ABSTRACT

Objetivo: El objetivo del presente estudio es evaluar los resultados motores y sensitivos obtenidos tras la reparación de los nervios mixtos del antebrazo con tubo de silicona. Material y métodos: Estudio retrospectivo de 14 pacientes afectos de 16 lesiones de los troncos nerviosos en el antebrazo (7 medianos, 7 cubitales, 1 rama radial sensitiva, 1 rama cutánea dorsal cubital) en los que se realizó neurorrafia directa con tubo de silicona. En 11 pacientes existieron lesiones asociadas arteriales y tendinosas. Se realizó reparación secundaria en tres casos y primaria en los 13 restantes, dos de ellos durante un reimplante de miembro superior. La valoración se realizó mediante la escala de funcional descrita por Chanson. Resultados: Con un seguimiento medio de 24 meses y excluyendo dos casos que afectaban únicamente a ramos sensitivos, se obtuvieron un 64% de buenos o muy buenos resultados, 24% de resultados regulares y un caso de mal resultado. En 6 casos se retiró el tubo, por tumoración palpable no dolorosa en la zona de inserción en 4 pacientes, por la existencia de clínica compresiva y por herniación de los extremos nerviosos en el interior del tubo en otro. En todos los casos se pudo comprobar la restitución macroscópica de la estructura nerviosa. Conclusiones: El uso del tubo de silicona en la reparación de lesiones agudas, subagudas y crónicas de nervios periféricos en el antebrazo parece aportar buenos resultados en la mayoría de los casos, con restauración macroscópica de la anatomía del nervio y restitución de la función (AU)


Objective: The aim of the present study is to evaluate motor and sensory results obtained after reconstruction of peripheral nerve injuries in the forearm, using silicone tubes. Methods: A series of 16 injuries of forearm nerves (7 median, 7 ulnar, 1 radial sensory branch, 1 dorsal ulnar cutaneous branch) repaired with use of direct neurorraphy through a silicon tube were retrospectively studied. Eleven patients suffered associated arterial and tendinous injuries. Secondary nerve repair was performed in 3 cases and primary repair in 13, two of them in the context of re-implant of the upper limb. The series was evaluated using the functional scale described by Chanson. Results: At a mean follow-up of 24 months, and having 2 cases excluded due to isolated injury of sensory branches, we obtained a 64% of good or excellent results, 28% of satisfactory results and 1 bad result. The tube was removed in 6 cases; 4 due to palpable painless tumour in the site of insertion, a case with compression symptoms after complete nerve function restoration and another that showed herniation of the stumps. In 5 cases the macroscopic restoration of the nerve was verified at the time of tube removal. Conclusion: The use of silicone tubes in the reconstruction of acute, subacute and chronic nerve injuries in the forearm seems to give good results in most of the cases, with macroscopic anatomy restitution of the nerve and good functional recovery (AU)

ABSTRACT

A case is presented of a bifid median nerve whose longest portion had a normal course while the other portion passed through a hole in the FDS tendon of the middle finger, at its musculotendinous junction. This caused nerve compression during muscle contraction, producing pain and dysaesthesia in the middle finger suggesting carpal tunnel syndrome.
