Gastrocnemius strain

Introduction Gastrocnemius muscle strain is a sports injury, mainly caused by acute indirect violence. It is related to the strong stress and external force of muscle active contraction. It often occurs in sports such as ball, jump or cross. It is a common training injury and injury in the army. One of the reasons for combat reduction is that the mild gastrocnemius muscle strain can be cured in a few days, and in the case of severe strain, the treatment time is longer and should be paid attention to. Physical examination revealed pain in the calf and even swelling. Local pain, tenderness, swelling, muscle tension, stiffness, cramps, dysfunction.

Physical examination: local pain, tenderness, swelling, muscle tension, stiffness, spasm, dysfunction. Pain worsens when the injured muscle is actively contracted or passively stretched. Muscle contraction resistance test is positive, that is, depression with increased pain or fracture occurs. Some wounded people have a tear-like feeling when they are injured, and the swelling is obvious and the subcutaneous congestion is serious. If there is a depression in the touch or an abnormal bulge at one end, the muscle may be broken. MRI and EMG determination can be done.

Differential diagnosis

Differential diagnosis of gastrocnemius muscle strain:

1, gastrocnemius tear: due to muscle damage, unable to support the tibia and tibial joints responsible for support and extension. If only one tendon is damaged, the symptoms are very mild. If both tendon tendons are broken, the tibial interface will be smoothed. Common in cattle and horses. Diagnosis by clinical symptoms. Similar to sciatic nerve injury, but mechanical damage is greater than neurological damage. The cause of the gastrocnemius laceration is the displacement of the bean bones of the ankles and the tail.

2, gastrocnemius contraction and pain: the scientific name of cramps is muscle spasm, is a spontaneous tonic contraction of muscles. The common leg cramps are actually calf muscle spasm, which means that the calf muscles such as the gastrocnemius suddenly become very hard and the pain is unbearable, which lasts for a few seconds to tens of seconds.

3, gastrocnemius tenderness: early clinical manifestations of leptospirosis, gastrocnemius tenderness, bilateral unilateral can also be unilateral, varying degrees. The lighter only feels the calf swelling, the mild pain of the pressure, the severe calf pain is severe, can not walk, refused to press. Leptospirosis, referred to as leptospirosis, is an animal-borne infection caused by pathogenic Leptospira. Rodents and pigs are the main source of infection and are prevalent worldwide. Clinically, it is characterized by early leptospirosis, intermediate organ damage and dysfunction, and various post-allergic symptoms. Severe patients may have liver and kidney failure and diffuse hemorrhage of the lungs, often endangering the lives of patients. The disease has spread over several continents, especially in the tropics and subtropics. The disease has been found in 28 provinces, municipalities and autonomous regions in China, and is highly prevalent in the central, southern, southwestern and eastern regions where rice is abundant. The onset season is mainly concentrated in the summer and autumn (June to October) rice harvesting period, often peaked from August to September, and the incidence rate of young and middle-aged farmers is higher. In areas with high temperatures, sporadic cases can be seen throughout the year.

4, gastrocnemius tendon pain: gastrocnemius tendon pain refers to one or both calves due to cold, or sudden changes in posture, etc., caused by gastrocnemius tendon, local pain, can not move.
