Abstract.

We performed a review of the literature between 1959 and 2001. We found 88 cases of suprascapular nerve entrapment, which fulfilled our inclusion criteria. Suprascapular nerve entrapment is rare and mainly occurs in patients under 40 years of age. Males are more likely to suffer from a ganglion compressing the nerve than females. If the patient's history reveals a trauma, it is more likely that the ligament is compromising the nerve. Ganglions usually cause isolated infraspinatus atrophy, whereas a combined atrophy of the supra- and infraspinatus muscles is more common in cases in which the nerve is compressed by the ligament.

Résumé.

Nous avons fait une révision de la littérature entre 1959 et 2001 et avons trouvé 88 cas de compression du nerf suprascapulaire remplissant nos critères d'inclusion. La compression du nerf suprascapulaire est rare et se produit surtout chez des patients de moins de 40 ans. Il est probable que les hommes ont, plus volontiers que les femmes, une compression ganglionnaire qui comprime le nerf. Si l'histoire du malade révèle un traumatisme, il est vraisemblable que le ligament est en cause. Habituellement les ganglions causent une atrophie isolée du muscle infraspinatus, alors qu'une atrophie combinée des muscles supra – et infraspinatus est plus commune lorsque le nerf est comprimé par le ligament.
