Cubital tunnel syndrome, the second most common compressive neuropathy, causes tingling and numbness in the ring and small fingers and can be treated with either a cubital tunnel release or an ulnar transposition. In this case, Dr. Asif Ilyas demonstrates the former on a cadaveric hand.

PREPRINT RELEASE: De Quervain’s Release

Instead of conducting a De Quervain's release on a patient with stenosing extensor tenosynovitis, Dr. Asif Ilyas walks through the procedure on a cadaver, demonstrating the approach to the first dorsal extensor retinaculum and providing tips to release it without injuring the radial sensory nerve.

PREPRINT RELEASE: Trigger Finger Release

When the flexor tendons of the hand thicken or become inflamed, stenosing flexor tenosynovitis of the hand (also known as trigger finger) develops. Dr. Asif Ilyas demonstrates on a cadaver how to perform the most standard trigger finger release, releasing the A1 pulley and then decompressing or releasing the flexor tendon.

PREPRINT RELEASE: Carpal Tunnel Release

Dr. Asif Ilyas performs a carpal tunnel release, the most common hand surgery, on a cadaveric hand. This surgery is typically done for paresthesia in the hand due to median nerve compression when non-operative treatment, such as splinting and injections, fails or becomes recalcitrant.
