ABSTRACT

Acute form of carpal tunnel syndrome is the less common presentation. Several etiologies are known as rheumatologic, hemopathic, endocrine or pregnant disorders and traumatic. Authors report a non yet described traumatic etiology, consecutive to hamate and triquetral fractures. Patient presented five hours after initial traumatism, a typical presentation of median nerve compression at wrist, with subjective and objective symptoms as pathologic Weber test. A classical median nerve release was performed in emergency. Nerve recuperation was complete two days after surgery, as usual in such pathology. This new etiology must be known; actually, nerve recuperation in acute carpal tunnel syndrome is time dependent.
