Background technique

Foot drop is one of the common diseases in orthopedic surgery. The patient is sitting, and the lower limbs hang naturally. If the foot is in plantar flexion and completely unable to actively dorsiflexion, varus and valgus, it is foot drop.

Patients with foot drop are due to long-term severe compression of the nerve roots (common peroneal nerve, foot nerve, sciatic nerve, lumbosacral nerve root, and cerebral nerve). The pressure on the surface of the nerve root exceeds 50mmHg for 2 minutes to cause nerve dysfunction, while at 100mmHg The above can lead to peripheral nerve injury of the foot, spinal motor nerve injury, muscular dystrophy, and joint flexion deformity, which in turn increases stiffness and activates the muscle structure around the joint, resulting in biomechanical changes. Foot drop is also a common complication in coma, paralysis, lower extremity dysfunction, and long-term bedridden patients.

For long-term bedridden patients or paraplegic patients, if the activities of the ankle joint are neglected, due to the effect of torque, the foot can rotate around the ankle and plantarflexion occurs. The ankle joint is in a state of plantar flexion for a long time, the front dorsal extensor muscles of the calf are stretched, and the rear plantar flexor muscles are shortened, followed by muscle atrophy, Achilles tendon shortening, and joint contracture, resulting in permanent foot drop deformity and inability to walk .

In addition, trauma is also one of the causes of foot drop.
