Sulcus-ulnaris-Syndrom: Einfache Dekompression oder subkutane Vorverlagerung?

Zusammenfassung

Ziel dieser prospektiven, randomisierten und kontrollierten Studie war die Evaluierung verschiedener operativer Techniken (subkutane ventrale Vorverlagerung oder die einfache Dekompression) zur Behandlung des Sulcus-ulnaris-Syndroms. Die Studie inkludierte 66 Patienten mit einem klinisch (Schmerzen mit und ohne neurologische Defizite) und elektrophysiologisch nachgewiesenen Sulcus-ulnaris-Syndrom. Bei 32 Patienten erfolgte eine Dekompression des N. ulnaris ohne Vorverlagerung, bei 34 Patienten eine Dekompression mit subkutaner ventraler Vorverlagerung. Die Nachuntersuchungen (3, 9 und 24 Monate Follow-up) beinhalteten die Schmerzevaluation mittels Visueller Analog Skala (VAS), sowie die Erhebung motorischer (Medical Research Council Scale) und sensibler (Sensory-Scale) Defizite. Die postoperativen, klinischen und elektrophysiologischen Ergebnisse zeigten keinen signifikanten Unterschied zwischen den beiden Operationstechniken (p > 0,05).

Abstract

The purpose of this prospective, randomised and controlled study was to evaluate which kind of operative technique for treatment of cubital tunnel syndrome is favourable: subcutaneous anterior transposition or nerve decompression without transposition. This study included 66 patients suffering from pain and/either neurological deficits with clinically and electrographically proven cubital tunnel syndrome. 32 patients underwent nerve decompression without transposition, whereas 34 underwent subcutaneous transposition of the nerve. Follow-up examinations evaluating pain, motor and sensory deficits as well as motor nerve conduction velocities were performed three, nine and 24 months postoperatively. Irrespectively of operative procedures (simple decompression vs. subcutaneous anterior transposition) there were no significant differences between the outcomes of the two groups at either postoperative follow-up examination (p > 0.05).
