The lateral trochlear ridge articulates with the posteromedial radial head with maximal joint contact in supination. This articulation is proposed to play a significant role in joint stability but may be prone to the development of osteoarthritis. 6,20

If an abnormality of the lateral trochlear ridge is seen or suspected, we recommend CT as the best imaging study to define these lesions. Keywords: Athletes; Elbow; Magnetic resonance imaging; Osteochondritis dissecans; X-ray computed tomography.

However, this technique is avoided due to concerns of articular impingement and cartilage damage. We set out to determine if there is a safe zone for fixation along the anterior lateral trochlea ridge (aLTR), and to ultimately to map this safe zone to guide screw placement.

2023年1月3日 · Transverse Trochlear Ridges The midtrochlear groove is partially or completely traversed by a nonarticular transverse bony ridge at the junction of the olecranon process and coronoid process. The bony ridge is devoid of articular cartilage and …

We set out to determine if there is a safe zone for fixation along the anterior lateral trochlea ridge (aLTR), and to ultimately to map this safe zone to guide screw placement.

Osteochondral lesions of the lateral trochlear ridge: a rare, subtle but important finding on advanced imaging in patients with elbow pain. Skeletal Radiol 2020; 49: 593–599.

2019年11月1日 · Five elbow radiographs were normal, one showed mixed lucency and sclerosis of the lateral trochlear ridge, and four demonstrated small osseous fragments adjacent to the ridge.

2019年8月7日 · Our primary research question was to anatomically determine if there is a non-articulating zone for screw placement along the anterior aspect of the lateral trochlear ridge (aLTR) throughout normal elbow range of motion. Eight fresh-frozen cadaveric elbows were used.

In the human arm, the humeral trochlea is the medial portion of the articular surface of the elbow joint which articulates with the trochlear notch on the ulna in the forearm. In humans and other apes, it is trochleariform (or trochleiform), as opposed to cylindrical in most monkeys and conical in some prosimians. [1] .

2019年8月7日 · Our primary research question was to anatomically determine if there is a non-articulating zone for screw placement along the anterior aspect of the lateral trochlear ridge (aLTR) throughout normal elbow range of motion. Methods: Eight …
