Joints are designed for movement, the rotating and angular movements between various bones are made possible by the joints that we have in our body. When joints are subject to strenuous work, sprains, dislocation and cracking joints are some of the issues that you have to deal with.
The joints in our body allow a wide range of movements ranging from the limited movements of the wrist to the complex rotating movements of the shoulder joints. The end of each of the bones is covered with a smooth thin layer of tissue called the synovial membrane. The two bony surfaces never touch and are always separated by the thin layer of fluid. Outside the synovial membrane the joint is enclosed by a tough, fibrous capsule. It is when this protective mechanism is disturbed that we experience the problem of cracking joints.
Joints are strengthened by bands of ligaments. Fibrous ligaments are elastic and cover all the joint surfaces; thereby acting as a kind of shock absorber. These ligaments complement the tendons and other connective tissue in maintaining the mobility of the joints. The numerous firm ligaments keep the joints together, connect the bones and give stability to the joints by preventing too free a movement and help to avoid cracking joints.
Let me explain this further with an example. The kneecap serves as protection for the front of the knee joint against the risk of an injury from external stress forces. As the knee bends the ligaments are stretched. If you crack the joints of your knee forcefully, it can lead to the problem of cracking joints in the knee accompanied by the swelling of the joint and the particular area. The affected joint then has to be rested in a position most comfortable for the patient for providing immediate relief.
Safeguard against Cracking Joints: Avoid all pressures on the affected joint to ensure proper healing. In case you find that the muscles surrounding the joint are sore, you could gently squeeze the muscles to improve the circulation and bring in a feeling of relief. You could also apply a cold compress at the affected area to bring in symptomatic relief. Do not forcibly crack your joints to relieve the stress, it only adds to the problem. The affected joint should be carefully manipulated by a medical practitioner and further deterioration should be prevented. Even mild injury to the bones can cause the problem of cracking joint.
