A case of peroneal neuropathy-induced footdrop - Correlated and compensatory lower-extremity function

This article reports on the case of a man with peroneal neuropathy-induced footdrop who was seen at the authors' institution 3 years after open reduct ion and internal fixation of a proximal fibular fracture and a distal, spir al, oblique tibial fracture of the right leg. A comprehensive gait analysis was conducted. A significant footdrop in gait resulted in a "reverse check mark" center-of-pressure pattern, an increased transverse-plane rotation o f the foot, and excessive knee and hip flexion in the sagittal plane. These objective findings documented significant dysfunction within the involved lower extremity; in addition, aberrant biomechanics were observed in struct ures other than the site of initial injury within both limbs.
