As our knowledge and technology advance, the indications for elbow arthroscopy continue to grow rapidly. During this expansion, a number of new portals have been described and reported using variable nomenclature and location descriptions. Accordingly, a comprehensive review of these portals is warranted. Given the concern for potential iatrogenic injury to surrounding neurovascular structures, a discussion of these critical nerves and vessels is also timely. In this work, we review pertinent surface anatomy; portal nomenclature, locations, and utility; and review distances to the nearest structures at risk...

Iatrogenic nerve palsies due to faulty positioning on the operating table are commonly seen over the elbow and popliteal fossa. However, injury to the brachial plexus (BP) is rarely encountered and is a recently reported phenomenon due to the increasing number of complex surgeries including hepatobiliary surgical procedures. Brachial plexus injury (BPI) needs to be recognized as a potential complication of prolonged abdominal surgery. The present case report highlights the potential for BPI and its early recognition, management, and prevention in complex prolonged abdominal surgical procedures...

BACKGROUND: Psychiatric patients are often kept immobilized during hospitalization to avoid self-inflicted injuries and danger to third parties. Inadequate positioning can lead to brachial plexus injuries (BPI). OBJECTIVE: To present a series of 5 psychiatric patients with BPI after being left sedated and restrained for prolonged periods of time during hospitalization. METHODS: We retrospectively reviewed the charts of 5 psychiatric patients with iatrogenic BPI referred by other institutions to our service...

INTRODUCTION: The clinical anatomy of the infrapatellar branch of the saphenous nerve (IPBSN) is of particular importance during operations in the area of the knee, especially when material for anterior cruciate ligament reconstruction is harvested. The nerve can easily be injured during the harvesting procedure, leading to postoperative complications that reduce quality of life. Three different skin incisions are commonly used during hamstring tendon harvesting: horizontal, vertical, and oblique...

Achilles tendon ruptures cause considerable morbidity and functionality reduction. There is lack of consensus regarding the best option for treatment following acute Achilles tendon rupture. Recent studies have failed to show substantial difference in outcome following conservative or operative treatment using an early active rehabilitation program. Meta-analyses have shown that conservative management has increased the risk of re-rupture, whereas operative intervention carries risks of complications related to the wound and iatrogenic nerve injury...
