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.

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.

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.

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.

PUBLISHED: Posterior Cruciate-Retaining Total Knee Arthroplasty

Richard Scott, MD
Professor of Orthopaedic Surgery, Emeritus

Abstract: Total knee arthroplasty has evolved into a very successful procedure to relieve pain and restore function in the arthritic knee with advanced structural damage. Optimal results are dependent on the restoration of alignment and ligament stability. Operative techniques involve either preservation of the posterior cruciate ligament or substitution of its function through increased prosthetic constraint. The vast majority of knees do not require cruciate substitution to establish appropriate stability and function. This video outlines the operative technique used by the author for posterior cruciate-retaining total knee arthroplasty in a patient with a preoperative varus deformity.

Dr. DiGiovanni fuses the subtalar joint of a patient suffering from posttraumatic arthritis.

The video-article includes an Introduction, Exposure (via Ollier approach), Preparation of the Articular Surface (with emphasis on proper articular denuding procedure), Bone Grafting (autograft from proximal tibia), the actual Fusion procedure, Closure and closing remarks by Dr. DiGiovanni about the importance and future direction for this particular arthritic pain relieving procedure.

Dr. Weaver treats a periprosthetic femur fracture with the patient positioned supine on a fracture table using a cephalomedullary nail. The fracture table provides adequate traction to assist in reduction of the fracture.

Dr. Weaver treats a periprosthetic humeral spiral fracture using contoured plating. The posterolateral approach helps prevent dissection of the triceps for adequate exposure of the fracture.
