Summary
Introduction

We propose our surgical experience and the decisional algorithm we use to select the surgical procedure for the ulnar nerve entrapment at the elbow according to defined parameters.

Materials and methods

Between 2005 and 2007, 44 patients were operated according to our algorithm that is based both on clinical parameters, classified through the McGowan scale, and on biological ones (the nervous morphology and the amount of scar around the medial epicondyle). Patients were treated through “modified” in situ simple decompression, subcutaneous and sub muscular transpositions.

Results

After an average follow-up of 13.4 months, function improved by one grade in 70% of patients, two grades in 16% and there was no change in 14%. Moreover 84,8% of patients operated through the modified in situ decompression technique reported an excellent outcome.

Conclusion

We suggest an algorithm for uniformly treat the patients with cubital tunnel syndrome through a clinical and biological point of view. The modified in situ decompression is a safe and effective treatment for the majority of these patients reducing the risk of redo surgery.

Resumen
Introducción

Proponemos nuestra experiencia quirúrgica y el método decisivo que utilizamos para elegir la técnica quirúrgica en el atrapamiento del nervio ulnar en el codo según parámetros concretos.

Materiales y técnicas

Entre el 2005 y el 2007, 44 pacientes han sido sometidos a cirugía según nuestro algoritmo basado en unos parámetros clínicos, clasificados a través de la escala de McGrowan, y otros biológicos (morfología del nervio y cantidad de cicatriz en torno al epicóndilo medial). Los pacientes fueron tratados mediante la decompresión simple “modificada” in situ, la transposición subcutánea y submuscular.

Resultados

Después de un control durante 13.4 meses, el 70% recuperó la función en un grado, el 16% en dos grados y no hubo cambios en el 14%.

Además, el 84,8% de los pacientes operados mediante la técnica de decompresión modificada in situ presentó excelentes resultados.

Conclusión

Proponemos un algoritmo para tratar uniformemente pacientes con síndrome del túnel cubital a través de puntos de vista clínicos y biológicos. La decompresión modificada in situ es un tratamiento seguro y eficaz en la mayor parte de pacientes reduciendo el riesgo de reintervención.
