Sonographic Evaluation Of Nerve Thickness In Traumatic Lower-Limb Amputees

All ultrasonographic examinations were performed by a single physiatrist experienced in musculoskeletal sonography. The full course of the sciatic nerve (SN), tibial nerve (TN), and common peroneal nerve (CPN) was assessed in a craniocaudal direction starting from the subgluteal fold to the popliteal fossa. The probe was placed axially on the nerves (perpendicular to the nerve) and the cross-sectional area (CSA) was measured at the same level proximal to the bifurcation for the SN , and at a point distal to the bifurcation of the SN for the TN and CPN (Figure 2). The values from the normal sides were accepted as controls.
