A rare case of subcutaneous traumatic index finger both extensor tendons rupture. Results of WALANT extensor digiti minimi transfer and literature review

Traumatic subcutaneous index finger both extensor tendons ruptures are rare injuries. Aim of the present paper is to review the literature about this uncommon lesion and to describe a case occurred to a 56 years old woman after a wrist forced hyperflexion trauma. An extensor digiti minimi (EDM) tendon transfer and a Pulvertaft tenodesis on the index EDC to the middle EDC using wide awake local anesthesia no tourniquet (WALANT) technique was performed after 7 days. The advantage of the technique is to allow immediate visualization of active motion and to evaluate proper tendon tensioning. In the reported case the patient recovered full function at 2 months and resumed manual working activity at 4 months. No complications occurred. (www.actabiomedica.it)
