Ulnar-Sided Wrist Pain in the Athlete.

Ulnar-sided wrist pain can be a challenging entity for the hand surgeon and even more so in the athletic population. The authors present 8 causes of ulnar-sided wrist pain in an athlete (hook of hamate fracture, pisiform fracture, hypothenar hammer syndrome, triangular fibrocartilage complex injuries, ulnocarpal impaction syndrome, lunotriquetral ligament tears, extensor carpi ulnaris tendinitis, subluxation of extensor carpi ulnaris) and their associated imaging and treatment options.

Modified AO arthrodesis of the wrist (with proximal row carpectomy).

A technique that has proven highly predictable and successful for arthrodesis of the wrist involves combining rigid internal fixation with concomitant removal of the proximal carpal row bones, which are then morselized and used for bone graft. Advantages of this procedure are (1) no distant bone graft site is required and (2) rigid internal fixation allows virtually immediate rehabilitation.

Quantification of the 5-year incidence of thromboembolic events in U.S. Air Force Academy cadets in comparison to the U.S. Naval and Military Academies.

The medical literature is replete with case reports of thromboembolic events related to high altitude exposure. Studies have shown an increased risk of thromboembolic events at high and very high altitudes. Most of these case reports and studies have been documented at altitudes between 3,000 m and 8,000 m (9,843-26,247 ft).
