An anatomic safe zone for posterior ankle arthroscopy: a cadaver study.

Posterior ankle arthroscopy has traditionally been associated with concern for injury to the posterior tibial nerve and vessels, and this concern is greatest when the patient is positioned supine. Positioning the patient prone could be a safer method for posterior ankle arthroscopy. The purpose of this cadaver study was to determine the anatomic safe zone devoid of vital structures relative to the posteromedial and posterolateral arthroscopic portals created.

Incidence of talar dome lesions with concomitant peroneal tendon pathologic features: a magnetic resonance imaging evaluation.

Few studies have evaluated the incidence of talar dome lesions and injuries to the peroneal tendons occurring concomitantly. The purpose of our research was to evaluate the incidence of osteochondral lesions of the talus (OLT) with peroneal tendon pathologic features according to the magnetic resonance imaging (MRI) findings. A database search was conducted in the Department of Radiology at the Western Pennsylvania Hospital and Forbes Regional Campus for all MRI examinations ordered by attending physicians of the Department of Foot and Ankle Surgery from 2008 to 2010.
