The first compartment is the most frequently affected site, called De Quervain's disease (syndrome or tenosynovitis). The other two most commonly injured are the sixth (extensor carpi ulnaris) and second (intersection syndrome) compartments. The first compartment is the site where entrapment tendinitis, better known as De Quervain's disease ...
A common injury to the extensor carpi ulnaris is tennis elbow. This injury occurs in people who participate in activities requiring repetitive arm, elbow, and wrist, especially when they are tightly gripping an object. Some symptoms of an extensor carpi ulnaris injury include pain when shaking hands or when squeezing/gripping an object.
The ECRB has additional origins from the radial collateral ligament, the ECU from the dorsal border of the ulna (shared with the flexor carpi ulnaris and flexor digitorum profundus), and all four also originate from various fascia. Moving distally, there are the abductor pollicis longus (APL), extensor pollicis brevis (EPB), extensor pollicis ...
Traditionally, people have speculated that tennis elbow is a type of repetitive strain injury resulting from tendon overuse and failed healing of the tendon, but there is no evidence of injury or repair, and misinterpretation of painful activities as a source of damage is common.

The common extensor tendon serves as the upper attachment (in part) for the superficial muscles that are located on the posterior aspect of the forearm: . Extensor carpi radialis brevis
Tendinopathy is a type of tendon disorder that results in pain, swelling, and impaired function. [2] The pain is typically worse with movement. [2] It most commonly occurs around the shoulder (rotator cuff tendinitis, biceps tendinitis), elbow (tennis elbow, golfer's elbow), wrist, hip, knee (jumper's knee, popliteus tendinopathy), or ankle (Achilles tendinitis).
Infectious tenosynovitis is the infection of closed synovial sheaths in the flexor tendons of the fingers. It is usually caused by trauma, but bacteria can spread from other sites of the body. Although tenosynovitis usually affects the flexor tendon of the fingers, the disease can also affect the extensor tendons occasionally. [5]
Medial injury of the flexor tendon is estimated to occur in 0.4% of the population. [1] It occurs most often in people ages 45 to 64, is more common in women than in men, and with 75% of cases in the dominant arm. [1] Risk factors for developing golfer's elbow include improper technique or lack of strength, endurance, or flexibility. [1]
