RESUMEN
Luxatio erecta is an unusual humeral dislocation. It is frequently associated with neurovascular injuries and concomitant fracture. As such, they require a thorough clinical and imaging evaluation. The vast majority of cases may be treated with closed reduction alone, but infrequently, some may require an open procedure. The authors report a case of luxatio erecta with fracture of greater tuberosity to underline the rarity of this entity, and to describe the mechanism of this injury and the therapeutic modalities.
RESUMEN
At the elbow, the ulnar nerve has a peculiar anatomic location which explains its high vulnerability. We here report five cases of post-traumatic ulnar nerve instability with complete nerve dislocation in front of the epitrochlea. In the light of our experience and review of the literature, the pathogenic, diagnostic and therapeutic aspects of this pathology are reviewed.
