Ulnar nerve transposition is a surgical procedure performed to treat ulnar nerve compression of the elbow, also known as cubital tunnel syndrome. This procedure is utilized after both non-operative management and in situ decompression fails, or if these procedures are deemed inappropriate based on patient pathology or ulnar nerve instability.

Transposition of the ulnar nerve involves not only decompression of the nerve but also its anterior repositioning to reduce compression and irritation while maintaining nerve integrity. This video demonstrates, on a cadaver arm, the operative technique for performing an ulnar nerve transposition using either a subcutaneous or a submuscular technique.

Cadaveric dissections of the temporal bone are a critical part of learning otologic surgery in residency. Dr. Scott Brown, neurotology fellow at the University of Miami, performs a step-by-step dissection of the temporal bone. He outlines key anatomical structures and describes safe and efficient techniques for these procedures.

Cubital tunnel syndrome is a condition that affects the ulnar nerve as it crosses the medial elbow through the retrocondylar groove. It is the second most common compressive neuropathy, causing tingling and numbness in the ring and small fingers. In advanced cases of symptomatic cubital tunnel syndrome, weakness, altered dexterity, and atrophy of the intrinsic muscles of the hand may develop. Cubital tunnel syndrome can be treated with either a cubital tunnel release or an ulnar transposition. In this case, the former is demonstrated on a cadaveric arm using the mini-open technique.

Carpal tunnel syndrome (CTS) is the most common peripheral compression neuropathy and results in symptoms of numbness and paresthesia in the thumb, index finger, middle finger, and half of the ring finger. When CTS symptoms progress and can no longer be managed with nonoperative measures, carpal tunnel release (CTR) surgery is indicated.

In this case, Dr. Asif Ilyas at the Rothman Institute performs CTR surgery on a cadaveric arm via the mini-open CTR technique. A 2-cm longitudinal incision was placed directly over the carpal tunnel, the transverse carpal ligament was exposed and then released, and the wound was closed. Patients are typically sent home with instructions to use their hand immediately postoperatively, while avoiding strenuous use until the incision has healed. Splinting and therapy are not required postoperatively.

This case presents a cadaveric demonstration of the coronal approach to exposing the upper or middle facial skeleton. This approach is commonly used when treating facial trauma such as frontal sinus fractures, orbital fractures, and zygoma fractures, as well as when taking a superficial temporal artery biopsy.
