Position-related brachial plexus injury may be diagnosed currently because of the rise in the number of laparoscopic colorectal surgeries being performed. The Trendelenburg position, which is necessary for laparoscopic and robotic surgeries, may lead to excessive pressure on the shoulders and thus cause brachial plexus injury. There are some risk factors like prolonged surgery and high BMI. Most patients recover with high-dose corticosteroid treatment and physical therapy. We report a case of brachial plexus injury caused by patient position during surgery.
