Lodge de Guyon syndrome

The Loge-de-Guyon syndrome is one of the nerve congestion/compression syndromes. In this syndrome, the ulnar nerve (“ulnar nerve”) is constricted in the constricted area of the wrist named after a Parisian doctor. The ulnar nerve is one of the three main branches of the brachial plexus, a nerve plexus that supplies the upper extremity.

It runs behind the elbow (the pain when bumping the “funny bone” is caused by an irritation of the ulnar nerve in its course there). It then runs along the forearm on the elbow side (small finger side) and reaches the palm of the hand in the area of the wrist through the Loge de Guyon, splitting into its two end branches in this area, a superficial branch (ramus superficialis) and a deep branch (ramus profundus). Motor nerve is involved in: Sensitively it supplies: The Loge de Guyon is a niche, which is essentially bounded by two of the carpal bones (Hamulus ossis hamati and Os pisiforme) and parts of the muscle-ligament apparatus (Retinaculum musculi flexorum, M. palmaris brevis). It is traversed by the ulnar nerve and the ulnar artery.

Cause of the Loge-de-Guyon syndrome

The cause of a narrowing of the nerve in the Guyon’s canal can be a ganglion (“overleg”), i.e. a benign tumor. Repeated long-term compression of the nerve by hyperextension of the wrist in its canal can also be a cause. This can occur for example with: Furthermore, previous fractures (breaks) in the area of the structures of the Guyon’s canal can lead to a narrowing.
