Manual treatment of sacroiliac joint dislocation is currently the most effective method. However, because of the severe irritation and pain caused by manipulation, some patients often have great fear of manipulation. In order to solve this defect, the sacroiliac joint is injected with local anesthetic, and then manipulation is performed under painless condition when the ligaments and muscles around the sacroiliac joint are relaxed, which has reduced the pain of manipulation and achieved satisfactory results. Manual rehabilitation 1.Flexion of hip and knee method (for anterior misalignment type) The patient is in supine position, the affected side is near the edge of the bed, the healthy side of the limb is naturally flat, and the hands are placed on the occiput. The operator stands on the affected side, pushes the affected limb deep and gently rotates inward with one hand, and presses the knee with the other hand to make the patient bend the knee and flex the hip. When he is not ready, flex the hip and knee joint to the maximum below the chest, and hear the “thump” sound, indicating successful reset. 2. Hyperextension of lower limb method (for posterior dislocation type) The patient is in prone position, the operator is on the healthy side, the right hand holds the affected ankle joint and gently externally rotates, the left hand presses the affected sacroiliac joint area. During the slow posterior extension movement of the affected limb, push the sacroiliac joint and the hyperextended affected limb while the patient is not prepared, and if the sound of joint repositioning can be heard or the feeling of repositioning appears under the operator, it indicates successful repositioning. After the manual rehabilitation, palm rubbing and massage around the sacroiliac joint and along the sciatic nerve can be used, and the patient can be assisted to move the affected limb in the supine position for more than 10 times, and when the effect is ideal, manual treatment can be performed again at intervals of 2~3 days.
