Lateral epicondylitis, also commonly referred to as tennis elbow, describes an overuse injury secondary to an eccentric overload of the common extensor tendon at the origin of the extensor carpi radialis brevis (ECRB) tendon. Tennis elbow primarily results from the repetitive strain caused by activities that involve loaded and repeated gripping and/or wrist extension. It is common in individuals who play tennis, squash, badminton, or any activity involving repetitive wrist extension, radial deviation, and/or forearm supination.
外侧上髁炎，通常也称为网球肘，是指桡侧腕短伸肌（ECRB）肌腱起点处的常见伸肌肌腱因离心超负荷而导致的过度使用损伤。网球肘主要由涉及负重和反复抓握及/或腕部伸展的活动所引起的重复性劳损导致。在打网球、壁球、羽毛球或任何涉及反复腕部伸展、桡侧偏斜和/或前臂旋后的活动的人群中很常见。
