Though this news was expected, the Kansas City Royals suffered yet another blow with word that Luke Hochevar will likely have to undergo shoulder surgery and miss the rest of the 2016 season. According to yesterday’s AP report, thoracic outlet syndrome is caused by blood vessels or nerves getting compressed between the collarbone and the first rib of the ribcage.
According to the Cleveland Clinic website, thoracic outlet syndrome is actually a group of disorders that can involve nerves or blood vessels. While the exact cause is unknown, it’s a common injury for people who play sports that involve repetitive arm movement.
