Isolated tibial paralysis


Usually due to lesions below the popliteal space such as gunshot, knife wound, auto accident, or leg fractures.  Affects plantar flexion, ankle inversion, foot adduction.  Dorsiflexion may be affected due to contractures of  the anterior tibialis.  Sensation is lost over the heel, lateral border, ungual surfaces, Edema is usual with causalgia, trophic changes, and trophic ulcers.  Partial lesions may spare the calf muscles and affect only the muscles of the foot, usually with prominent pain.
