The foot has six acetabula (joint sockets) and four fragile bones. Whenever there is dislocation at the junction of bones on the sole of the foot, one person must pull the limb while another uses their hand to palpate the bone joints or prominences. If the bone is displaced outward, it should be pulled from the outside back to the inside; if displaced inward, it should be forcefully pulled back to the inside to restore it to its socket. If only traction is used without manual reduction into the socket, it may cause misdiagnosis and lead to chronic disability. It is advisable to apply Jiagu Gao (Bone-Setting Plaster) and Dingtong Gao (Pain-Calming Plaster), and to splint the four fragile bones using primary and secondary splints for binding. For dislocations of the six acetabula, only cloth wrapping and binding are suitable; splints should not be used. Dislocations of the ankle and knee are similar to those of the elbow in the arm; whether displaced inward or outward, fixation with a splint on one side is sufficient. This area contains numerous tendons and vessels, so the joint should be flexed and extended frequently rather than kept immobile, to prevent re-dislocation. Careful observation is required, and negligence must be avoided. Jiagu Gao and Dingtong Gao should be applied and splinted.

For dislocation at the root of the thigh, the pelvic bone acts as the acetabulum, and the femoral head as the condyle. Whether displaced anteriorly or posteriorly, one person must hold the patient's body steady while another pulls the leg and manually manipulates it to achieve reduction. If manual reduction fails, soft cotton ropes can be tied around the foot, suspending the patient upside down. Manual adjustment of the joints combined with gravitational traction can naturally restore the bone to its socket. Subsequently, Jiagu Gao and Dingtong Gao should be applied and splinted.

For fractures of the vertebral column, manual manipulation is contraindicated. Instead, soft ropes should be used to suspend the patient by the feet, allowing the body to hang vertically. The bones will self-reduce. If the body is not straight, reduction has not occurred. One must wait until the spine is straight and the bones are reduced, then apply Jiagu Gao, Dingtong Gao, or Burou Gao (Flesh-Replenishing Plaster). Place a piece of mulberry bark on the medication, followed by two or three pieces of cedar bark on top of the mulberry bark. Bind tightly with soft materials to prevent curvature, and treat with medication. For crushed bones in the hands or feet caused by compression, administer Mayu (Anesthetic Medicine) orally, or use a knife to scrape away debris. In severe cases, bone fragments may be trimmed with scissors to prevent them from piercing the flesh. If comminuted, remove the bone fragments to avoid complications such as pus and blood loss. Then, apply large pieces of mulberry bark coated with Burou Gao or Dingtong Gao onto the bone and flesh interface, ensuring correct placement. Clean the wound every three days to prevent foul odor, and continue treatment with medication. Do not casually rely on the availability of medicines to perform unnecessary cutting, trimming, or manipulation. Detailed examination is essential; surgical intervention should only be performed when indicated, with utmost care. For injuries to the head, whether from blunt trauma, lacerations, or crushing fractures, apply medication and bandage. During application and bandaging, ensure the environment is enclosed and windless to prevent wind from entering the wound, which could lead to Tetanus (Po Shang Feng). Remember this well.
