Biceps Tendon Tear at the Elbow - OrthoInfo - AAOS
The tendon at the elbow is called the distal biceps tendon. It attaches to a part of the radius bone called the radial tuberosity, a small bump on the bone near your elbow joint. The biceps muscle helps you bend and rotate your arm.
Distal Biceps Avulsion - Shoulder & Elbow - Orthobullets
2024年10月30日 · Distal Biceps Avulsions are injuries to the biceps tendon at the radial tuberosity insertion that generally occurs due to a sudden excessive eccentric contraction of the biceps brachii. Diagnosis can be made clinically in the setting of complete tears with a hook test. MRI studies can be used to discern between a complete tear and a partial tear.
Distal Biceps Tendon Tear: Causes, Symptoms, Treatment | HSS
2024年4月12日 · Repair involves surgical reattachment of the distal biceps tendon to the radius bone at the radial tuberosity, where the tendon naturally inserts into the bone. Surgery is typically performed through a single incision in the front of the elbow or two-incision approach, in which a small second incision is made at the back of the elbow.

2021年11月29日 · Attachments. The distal tendon of the long head biceps muscle belly features an oval-shaped insertion onto the large proximal part of the bicipital tuberosity a bit more posteriorly, whereas the distal tendon originating from the short head of the biceps muscle attaches onto the distal portion of the bicipital tuberosity with a fan-shaped ...
Distal Biceps Tendon Rupture Elbow | Radsource
The distal biceps tendon attachment to the bicipital tuberosity of the proximal radius is best demonstrated on axial images. A normal tendon (arrows) demonstrates low signal on T1-weighted (left) and fat-suppressed T2-weighted (right) images.
Distal biceps tendon injury | Radiology Reference Article - Radiopaedia.org
2024年3月28日 · Partial and complete tears are characterized by partial or complete tendon discontinuity or detachment and/or peritendinous effusion with or without fiber retraction, whereas other alterations of the tendon without any evidence of fiber disruption (such as mere loss of the fibrillary pattern) indicate minor injuries as tendinopathy or elongation...
Partial tear of the distal biceps tendon: Current concepts
Patients with partial rupture of the distal biceps tendon can present with vague elbow pain and weakness. Understanding of the anatomy and aetiology of this disease is essential to management. Patients can present with a single or multiple traumatic events or with a chronic degenerative history.
A 3-Dimensional Anatomic Study of the Distal Biceps Tendon
2015年6月2日 · Complete rupture of the distal biceps tendon from its osseous attachment is most often treated with operative intervention. Knowledge of the overall tendon morphology as well as the orientation of the collagenous fibers throughout the musculotendinous junction are key to intraoperative decision making and surgical technique in both the acute ...
Distal Biceps Tendon Rupture - Physiopedia
Common symptoms of a biceps tendon rupture include pain, ecchymosis and oedema around the antecubital fossa. A popping sound at the moment of rupture is often reported. Avulsion of the distal tendon results in weakness at the elbow, with reported decreases in elbow flexion and supination of up to 40% and 50%, respectively.
Anatomy of the Biceps Tendon: From Origin to Insertion
2021年1月26日 · Distally, the tendinous insertion of the biceps rotates 90 degrees externally from its origin and attaches to the ulnar aspect of the radial tuberosity. The biceps brachii functions as the primary supinator of the forearm and a secondary elbow …
