The currently used phase I surgery for cerebral palsy refers to the FSPR procedure, which is unique in relieving muscle spasticity in patients with cerebral palsy, but is difficult to perform in the correction of joint deformities and soft tissue contractures. Therefore, the second stage of cerebral palsy surgery, Cerebralpalsymusclestrengthmuscletensionadjustmentmethod (CP-MMA), is needed to effectively release contractures and stabilize joints. Cerebral palsy muscle tone adjustment loosens spasms and contractures and creates conditions for functional recovery by cutting off the motor branches of certain muscles, mainly giving the removal of a spastic muscle muscle branch, which can be weakened so that the antagonistic muscles of its strength are equal. Barnett used local infiltration of procaine for temporary paralysis, and although temporary paralysis of the muscle branch of the nerve can occur, it is difficult to know the persistence of the nerve paralysis after procaine infiltration and the patient’s ability to adapt to the new muscle group coordination in such a short period of time. The effect of neurotomy can only be properly evaluated when the severed branches regenerate gradually. For joints that cannot be stabilized by myotonic adjustment in cerebral palsy, if the deformity of the bone or joint is still developing under non-surgical treatment, soft tissue surgery alone cannot achieve satisfactory results and needs to be combined with bone or joint surgery to avoid deformity and obtain stability. These surgeries include bone lengthening or shortening, osteotomy and joint fusion, keeping in mind that the deformity is also adapted to skeletal surgery for correction. They are usually administered after the age of 10 to 12 years. The use of orthopedic surgery can stabilize uncontrollable joints and achieve satisfactory results. Triple joint fusion can stabilize balance disorders and improve foot deformities. External fixation of the subtalar joint is indicated for the correction of horseshoe deformity of the foot. Also in the case of wrist deformities, wrist fixation often produces satisfactory results. If the patient can derive maximum benefit from the procedure and will maintain it for a period of time, it should be closely monitored; inadequate treatment after surgery often causes recurrence of the deformity. Treatment should therefore be maintained until the child is fully skeletally mature. The principles of muscle tone adjustment surgery for cerebral palsy 1. Upper limb deformities are corrected distally before proximally, and lower limb deformities are corrected proximally before distally; 2. In older children with fixed foot deformity, it is not advisable to perform tendon transposition alone, and it is advisable to cooperate with and choose bony surgery. Lastly, it is important to emphasize that cerebral palsy muscle tone adjustment surgery is different from ordinary orthopedic surgery, which includes bone anchor nail implantation technique + muscle tone adjustment + orthopedic + plaster fixation. The bone anchor nail implantation technique is to firmly bond the displaced tendon with the bone of the dorsal foot through imported bone anchor nails, effectively avoiding the anastomosis of the tendon from tearing off, and is to adjust the balance of muscle strength and tone of the limbs through the lengthening, shortening and displacement of the tendon.
