旋转带肌腱炎

　　旋转带肌腱炎常发生在需要肩关节极度外展的反复运动中(如棒球、自由泳、仰泳、蝶泳、举重、球拍运动)。当上肢前伸时，肱骨头向前撞击肩峰与喙肩韧带，引起冈上肌腱损伤。慢性刺激可以引起肩峰下滑囊炎、无菌性炎症和肌腱侵蚀。急性的巨大暴力可以导致旋转带断裂。

　　发生旋转带肌腱炎的患者，如果不注意休息或进行治疗，由于病变所在部位运动过多，常常造成病情不断地加重。在后期其主要的并发症包括慢性肿胀(重力性水肿)、肌萎缩、撕脱性骨折、关节僵直、韧带松弛等。

　　旋转带肌腱炎的初期，疼痛只发生在上臂高举过头和用力外展时。以后，伸臂握手时也会出现疼痛。通常情况下，疼痛在向前推物时发作，而拉东西时则没有或仅有轻微疼痛。当上臂伸直，肩关节内旋外展时，旋转带有压痛，尤其是患肢高于肩关节平面时（若患肢低于体侧，则无压痛）。患肢内收过胸亦会引发剧痛。肩关节外展肌力的下降通常是由于三角肌的废用性萎缩。

　　The main preventive and health care measures for the prevention of rotator cuff tendinitis are as follows:

　　1Supplementing vitamins is beneficial for the healing of tendinitis. Supplement vitamin C every day1000 milligrams, β-Carotene (Vitamin A)10000 international units. Do not perform actions that cause joint sprains.

　　2Before exercising, it is necessary to warm up thoroughly, especially for athletes.

　　3If tendinitis is caused by work and it is necessary to continue working, stretch the lower body before and after work. Use it every hour5-10rest for a minute. Avoid overexerting the injured area while working.

　　To exclude the possibility of bone injury in the case of rotator cuff tendinitis, in cases where it is difficult to diagnose, X-ray examination should be performed. Magnetic resonance imaging can help determine the severity of the tendon injury. Although MRI cannot indicate partial tearing of the rotator cuff, it can show complete tearing, which is of certain significance for differential diagnosis.

　　The diet for rotator cuff tendinitis should be light, with a high intake of vegetables and fruits, a reasonable diet combination, and attention to adequate nutrition. It is appropriate to consume animal blood, eggs, fish, shrimp, soy products, potatoes, beef, chicken, and ox 'tendon' meat, which are rich in histidine, arginine, nucleic acids, and collagen. Patients should eat less spicy, greasy, and indigestible foods.

　　The tendons injured should be given adequate rest and the muscles of the healthy shoulder should be strengthened. Patients should avoid pushing actions and instead perform pulling activities (when there is no pain). If the injury is particularly severe, with complete tearing of the rotator cuff, or if the pain is6If it does not disappear within the month, surgical treatment is required.
