Anatomic considerations of pin placement in the proximal tibia and its relationship to the peroneal nerve

Peroneal nerve impalement is a recognized complication of percutaneous placement of wires, which is gaining increased usage with the application of the techniques of Ilizarov, Monticelli, and Spinelli. Dissections of the peroneal nerve in the proximal tibia were performed in ten anatomic specimens (20 legs) to define (1) its relationship to palpable landmarks, (2) distribution of major branches to the musculature, and (3) safe zones of placement of percutaneous wires in the proximal tibia. The anterior recurrent tibial nerve was frequently in an area of risk where it courses proximally in the anterior compartment. A safe zone is located anterior to the palpable portion of the fibular head and up to 2 cm distal to the tip of the fibular head.
