What does a triceps tendon tear look like on ultrasound? What do injuries of the triceps tendon look like with ultrasound imaging? The top image shows the distal triceps tendon with tendinosis at its attachment on the proximal ulna (the olecranon process). The distal tendon is thickened with a loss of normal fibrous echotexture. There is hypoechogenicity (darkening) of the superficial layer of the conjoined tendon (white arrow) compared to the deep portion (orange arrow) and a loss of the normal tendon tapering conformity at the insertion on the olecranon. The bottom image shows a selective area of complete fiber non-visualization of the distal triceps tendon’s superficial portion near its insertion on the olecranon (white arrow), demonstrating a high-grade partial tendon avulsion/tear. Note that the deep fibers of the medial…

What causes loss of strength in the triceps? Causes for triceps weakness, particularly when only one arm is affected, include direct injuries to the triceps tissue and injury to the nerves that innervate it. Starting at the top and working down, here are the primary injuries that can cause a loss of triceps strength: 1. Cervical Stenosis Narrowing of the bony passages between cervical vertebrae can put pressure on nerves traveling through and exiting the spinal column. The C7 nerve root typically contributes the most innervation to the triceps; narrowing of the C6-C7 intervertebral foramen or bulging of the intervertebral disc at this level can compress the C7 nerve.  2. Axillary Neuropathy Sometimes, the motor branch of the long head of the triceps is supplied by the axillary nerve rather…
