In this video, Dr. Pratt goes over airway management techniques in trauma resuscitation. It outlines the preparation and equipment used in patients with impending airway failure that require manual or mechanical ventilation. Also discussed are the innovative airway towers used in the University of Chicago emergency room as well as the general approach to airway management. The different types of laryngoscopy, assist devices, and cricothyroidotomy surgical airway procedures are also presented.

This video covers information related to the FAST exam, which evaluates the pericardial, hepatorenal, splenorenal, and suprapubic regions for free fluid in a trauma patient as well as the extended version, which includes an additional evaluation of the pleural spaces for a pneumothorax. It goes through probe selection, probe placement and image acquisition, image optimization, and pitfalls and pearls for the subxiphoid/subcostal, right upper quadrant, left upper quadrant, suprapubic, and pleural views.

Subtalar Arthrodesis for Post-Traumatic Subtalar Arthritis

Massachusetts General Hospital

Subtalar arthrodesis is currently the mainstay treatment option for the management of recalcitrant subtalar arthrosis.

The patient in this case is a 45-year-old male who developed post-traumatic arthritis of the subtalar joint 14 years following a work-related injury in which he sustained a comminuted, joint-depression type calcaneal fracture after a 10-foot fall from a ladder. Seven years after the initial injury, imaging prompted by progressive hindfoot pain during weight-bearing or following activity revealed progressive degeneration of the subtalar joint, for which he was treated with orthoses, corticosteroid injections, and arthroscopic debridement. After exhausting both conservative and minimally invasive treatment measures at 14 years post-injury, he finally elected to undergo subtalar arthrodesis.

This video article details the methods and techniques involved in subtalar arthrodesis. After an Ollier approach was used to expose the subtalar joint, the arthritic cartilage was removed and the subchondral plate was perforated. Finally, an autogenous bone graft was harvested from the proximal tibia and inserted into the joint space, and compression was achieved by two lag screws.

The patient in this case is a 76-year-old male who was admitted to the ER two weeks prior and was found to have an obstructing, 1-cm left proximal ureteral stone with a forniceal rupture. A left ureteral stent was placed, and he was started on antibiotics. In this video, Dr. Ryan Hankins at MedStar Georgetown University Hospital performs definitive management of the stone with a left ureteroscopy, laser lithotripsy, and stent replacement.

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 Release (Cadaver)

Asif M. Ilyas, MD
Professor of Orthopaedic Surgery
Program Director of Hand Surgery
Rothman Institute, Thomas Jefferson University

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.
