Acute post-operative airway complications following anterior cervical spine surgery and the role for cricothyrotomy.

Anterior cervical spine surgery (ACSS) is a common procedure, but not without its own risks and complications. Complications that can cause airway compromise occur infrequently, but can rapidly lead to respiratory arrest, leading to severe morbidity or death. Knowing emergent post-operative airway management including surgical airway placement is critical. We aim to review the different etiologies of post-operative airway compromise following ACSS, the predictable timeline in which they occur, and the most appropriate treatment and management for each. We place special emphasis on the timing and proper surgical technique for an emergent cricothyrotomy. Angioedema is seen the earliest as a cause of post-operative airway compromise, typically within 6-12 hours. Retropharyngeal hematomas can be seen between 6-24 hours, most commonly within 12 hours. Pharyngolaryngeal edema is seen within 24-72 hours. After 72 hours, retropharyngeal abscess is the most likely etiology. Several studies have utilized delayed extubation protocols following ACSS based on patient risk factors and found reduced postoperative airway complications and reintubation rates. The administration of perioperative corticosteroids continues to be controversial with high-level studies recommending both for and against their use. Animal studies showed that after cardiac arrest, the brain can recover if oxygenation is restored within 5 minutes, but this time is likely shorter with asphyxia prior to cardiac arrest. Experience and training are essential to reduce the time for successful cricothyrotomy placement. Physicians must be prepared to diagnose and treat acute postoperative airway complications following ACSS to prevent anoxic brain injury or death. If emergent intubation cannot be accomplished on the first attempt, physicians should not delay placement of a surgical airway such as cricothyrotomy.

Case report: Acute cubital tunnel syndrome in a hemophiliac patient.

A 24-year-old right-hand dominant male with severe Hemophilia A presented with acute elbow pain, associated paresthesias, and weakness in the ulnar nerve distribution after upper body weight lifting. In the week prior, he missed three doses of Factor VIII replacement. After no improvement with conservative measures, he was taken to the operating room urgently for decompression and was noted to have a perineural hematoma in the cubital tunnel. At final follow-up, the patient reported complete resolution of symptoms. Acute cubital tunnel syndrome in hemophiliac patients that does not respond to medical treatment is best treated with surgical decompression using minimal dissection to prevent hematoma formation, preserve perineural membranous tissue, and avoid destabilizing the nerve.

Outcomes of distal humerus diaphyseal injuries fixed with a single-column anatomic plate.

PURPOSE: The locking compression extra-articular distal humerus plate (EADHP) is an anatomically shaped, angular stable single-column fixation system for distal third humerus fractures. The purpose of this retrospective study was to evaluate clinical and radiographic outcomes after open reduction and internal fixation of distal humerus fractures with this device. METHODS: Twenty-one consecutive patients with distal humerus fractures were treated with the EADHP system between February 2006 and June 2012. Of these, 19 were clinically and radiographically evaluated after a mean follow-up of 10.4 months. Follow-up assessment included anteroposterior and lateral radiographs, assessment of range of motion (ROM), pain according to a visual analogue scale (VAS) and Disabilities of the Arm, Shoulder and Hand (DASH) score. RESULTS: All fractures demonstrated satisfactory reduction and healing at an average of 7.3 months. One patient showed post-operative sensory ulnar neuropathy that recovered completely, and nine patients had a preoperative radial nerve palsy, which recovered spontaneously following exploration and plating. Mean post-operative ROM was as follows: flexion 126°, extension -7°, pronation 82° and supination 83°. The VAS score was zero points in eight patients, while the mean DASH score was 25.8 points. CONCLUSIONS: For extra-articular distal humerus fractures, including high-energy injuries often seen in gunshot wounds or motor vehicle injuries, the anatomically shaped angular stable single-column plate provides satisfactory clinical and radiographic results and serves as a valuable tool in the treatment of these injuries.
