The plantar bulge is a clinical manifestation of congenital vertical talus, the anterior part of the foot has dorsal extension and abduction deformity, the dorsal foot muscles, tibial navicular ligament and talar navicular ligament are often tense, contracture and affect the plantar flexion and inversion of the anterior part of the foot, the heel exostosis deformity causes the muscles, tendons and ligaments of the posterior part of the foot to shorten, due to the stiff ankle joint, activity is limited, the foot deformity is heavy, the patient can’t land on the heel when standing or walking, unstable gait, slow walking The affected foot is prone to fatigue and pain. What are the concomitant symptoms of plantar bulge? Gait instability: refers to unstable walking, or see the movement is not flexible, walking two legs are very wide; or walking can not walk straight, left and right; or walking with a short step, two upper limbs do not swing back and forth, the initial walk slowly, and then more and more fast, “panic gait”. Such as ataxia, drunkenness, etc. Foot deformity: refers to the abnormality of foot shape or structure, the normal human foot shape is maintained by the relative proportion of external and internal muscles to maintain its balance, some congenital or induced disease causes can cause foot deformity. Joint stiffness: refers to the normal joint function (such as flexion and extension, rotation, etc.) occurs in different degrees of impairment, manifested by the reduction of the range of motion and the complete loss of function of the joint strong to very different. Giant foot: Abnormal development of the foot or toes into malformed tissue due to diseases such as congenital macrodystrophy, which makes the patient’s foot larger than normal. Dural bulge: Various congenital developmental abnormalities of the spinal cord and spinal ends can lead to spinal bulge. Due to congenital factors resulting in incomplete closure of the vertebral plate, there is concurrent bulging of the spinal membrane, spinal cord, and nerves into the defect of the vertebral plate. How should a patient with plantar bulge be diagnosed? Early treatment of this disease is expected to correct the deformity, so early diagnosis is more important for prognosis. The diagnosis of plantar bulge is not very difficult based on medical history, clinical manifestations and X-ray examination. Some scholars have proposed three X-ray signs as a clinical diagnostic reference: 1. large axial angle, with significant differences from the normal control group; 2. non-continuity of the axis; 3. displacement of the axial intersection.
