2016年1月17日 · Placing the probe in the axial position at the uppermost part of the wrist will reveal EC1 and its two tendons, the abductor pollicis longus and extensor pollicis brevis. The two tendons are surrounded by a tendon sheath and contained within the extensor retinaculum.

The ECU tendon runs down the forearm, crosses the wrist, and attaches to the base of the fifth metacarpal bone in the hand. This tendon plays a key role in ensuring wrist stability and enabling certain movements that involve the hand and forearm, such as lifting things, gripping objects, and bending the wrist.

2025年1月3日 · The distal intersection syndrome relates to tenosynovitis of the extensor pollicis longus (EPL) tendon (3 rd extensor compartment), where it crosses the extensor carpi radialis longus (ECRL) and brevis (ECRB) tendons (2 nd extensor compartment) 1.

2016年10月11日 · The tendons of the wrist are commonly symptomatic and can be injured, infected, or inflamed; this article reviews their normal appearance at MR imaging and US, discusses relevant anatomy, and gives an overview of common pathologic conditions that affect the wrist tendons.

2023年8月28日 · At the wrist, the extensor retinaculum of the hand overlies the tendons of the extensor compartment of the wrist. It provides support as well as prevents bowstringing of the tendons. [3] The first extensor compartment is comprised of the APL and EPB tendons.

2023年10月7日 · Intersection syndrome is an inflammatory condition located in the distal radial forearm where the tendons of the 1st extensor compartment cross over the tendons of the 2nd compartment. Patient usually presents with pain, crepitus, and squeaky sensation in the dorsal distal forearm. May have localized swelling.

2012年11月23日 · At the dorsum of the wrist, the extensor retinaculum is a fibrous band that holds the extensor tendons in place and prevents bow-stringing (Figs. 1 and 2). By extending fascial attachments to the underlying bones and periosteum, the retinaculum forms six compartments over the dorsal wrist, each of which contains various tendons [2, 3].

2005年11月1日 · The anatomy of the wrist and hand is best described by considering the extensor and flexor surfaces separately. The carpal extensor retinaculum divides the dorsal extensor tendons into six separate synovial compartments, which are demarcated by the points of its attachment to the radius and ulna.
