Recovery of ankle dorsiflexion weakness following lumbar decompressive surgery.

This retrospective study evaluated the recovery of ankle dorsiflexion (ADF) weakness following decompressive surgery in order to identify factors indicative of a better outcome. Fifty-six consecutive patients with ADF weakness secondary to nerve root compression underwent lumbar decompressive surgery. The demographic features, duration and severity of preoperative ADF weakness, associated radicular pain, as well as the radiological and intraoperative findings were recorded.
