Failed ulnar nerve surgery due to persistent unrecognized snapping triceps from cubitus varus due to a distal humeral malunion in an adult: illustrative case.

Background: Snapping triceps is a dynamic condition in which a portion of the medial head of the triceps dislocates over the medial epicondyle during flexion or extension. Pushed by the triceps, the ulnar nerve typically also dislocates over the medial epicondyle, causing neuropathy. Posttraumatic cubitus varus deformities resulting from pediatric supracondylar fractures have been associated with snapping triceps.

Spatio-Spectral Ultrasound Characterization of Reflection and Transmission Through Bone With Temperature Dependence.

Transcranial focused ultrasound (tFUS) is a promising approach for the treatment of neurological disorders. It has proven useful in several clinical applications, with promising outcomes reported in the recent literature. Furthermore, it is currently being investigated in a range of neuromodulation (NM) and ablative applications, including epilepsy.
