In 1881, Valkmann first reported a case of contracture, he proposed that after trauma to the upper limb, strangulation due to over-tightening of the bandage can cause ischemia and contracture of the forearm muscles, so the nomenclature of this particular part of the fascial interstitial compartment syndrome, traditionally known as the ischemic contracture of the forearm.In 1978, Muborak proposed the following definition for the Volkmann’s contracture (the fascial interstitial compartment syndrome of the forearm and the secondary In 1978, Muborak defined Volkmann’s contracture (forearm fascial compartment syndrome and secondary ischemic myoclonus) as follows: Volkmann’s contracture refers to a series of symptoms that occur in the confined fascial compartment of the forearm as a result of elevated tissue fluid pressure, which leads to impaired circulation to the muscles and nerves in the fascial compartment. Determination of the internal pressure of the forearm fascial interstitial compartment, the normal is 0-8mmHg (1kPa = 7. 5mmHg), when the occurrence of fascial interstitial syndrome, its internal pressure can reach 30-50mmHg, and sometimes even as high as 80mmHg. There are a lot of causes of ischemic contracture, and the pathogenesis is very complex. Tissue ischemia after limb and vascular injury is the main cause of elevated tissue pressure within the interfascial compartment, followed by impaired circulation, altered hemodynamics, impaired microcirculatory function, ischemia-reperfusion injury, imbalance of interstitial fluid balance and dysfunction. If left untreated, this vicious cycle can continue over and over again, leading to progressive muscle necrosis. The intrinsic fascia of the forearm, the interosseous membrane of the ulnar radius and the interosseous membrane divide the forearm into flexor (palmar) and extensor (dorsal) fascial compartments. (1) Palmar fascial compartment: (1) Upper part: the deep fascia of the elbow fossa and the biceps tendon membrane intertwine with each other to form a rhomboid tendon plate, which covers the superficial surface of the brachial artery and wraps around the anterior rotator cuff, anterior rotator anterior, brachioradialis, and flexor digitorum profundus muscles, as well as their deep surface of the median nerve. (2) Middle and lower part: the fascial fibers are transverse, and the fibers are strengthened to maintain the position of the muscles and tendons. The radial artery, palmar interosseous artery and ulnar artery of the forearm, superficial branch of the radial nerve, median nerve and ulnar nerve are all traveling in this fascial compartment. Extensor fascia intermedia: The dorsal fascia of the forearm is reinforced by fibers of the triceps tendon membrane, which constitutes the hard posterior wall of the dorsal fascia intermedia chamber, the anterior wall of the interosseous membrane, and the ulnar-radial bone on both sides. The compartment contains all extensor and posterior rotator muscles, the deep branch of the radial nerve and the dorsal interosseous artery. Agerelated contracture is a condition in which a muscle or group of muscles and joints are in a constant state of spasm or in a particular position, resulting in muscle atrophy, joint deformity and immobilization, which in turn causes dysfunction of the organism. It can be complicated by myasthenia gravis, joint deformation, periarticular ligament fibrosis, destruction of soft tissue structure, and limited movement of bone bridges in the joint space. Myasthenia gravis also has neurogenic myasthenia gravis and myogenic myasthenia gravis; the former is caused by lower motor neuron lesions, and the latter is caused by muscle vascular lesions or mechanical injuries resulting in inflammation or defects of muscle fibers. The former is caused by lower motor neuron disease, and the latter is caused by muscle vascular disease or mechanical injury resulting in inflammation or defects of muscle fibers. Prevention: early active or passive exercise and appropriate functional exercise, put the joints and limbs in a certain position and change the position in time; application of drugs, physical therapy or joint traction and other measures to reduce the body pain; these methods are important measures to prevent the occurrence of contracture. Generally speaking, as long as the indications are properly mastered, early exercise therapy will have no effect on the primary disease.
