We present a 38-yearold female who was riding a personal watercraft when she was struck by an ocean wave and ejected backwards. The motor exam demonstrated bilateral upper extremity weakness. Brachial plexus MRI revealed left C4-C5 and C5-C6 nerve root sleeve tears, with possible similar contralateral injuries. The patient was observed for two days without clinical improvement and was sent home with an appointment to the peripheral nerve clinic and evaluation with a physiatrist. She completed six weeks of physical therapy, achieving substantial improvement, and recovered completely six months later. Traction of the brachial plexus can occur when an individual hangs onto the handlebars with the involved arm while being ejected from a personal watercraft. The expulsion causes a forceful separation motion of the shoulder with respect to the arm or the head with respect to the neck.  \nCategories: Sports Medicine, Trauma, Neurosurgery  \nKeywords: brachial plexus, injury, jet ski, nerve root, ocean, personal watercraft, traction  \nIntroduction  \nAmong trauma patients, approximately 1% suffer brachial plexus injuries, most commonly secondary to motorcycle and snowmobile accidents [1] . However, the incidence of injury with motorcycle or snowmobile accidents approaches 5%[1] . The injury to the brachial plexus can be complete or only involve the upper or lower plexus, or a combination of both. Complete lesions have a prevalence of 53%, followed by upper plexus lesions at 39%, and lower plexus injuries at 6%[2] . Several mechanisms for traumatic injury to the brachial plexus have been described, usually involving a forceful stretch of the arm concurrently with extreme motions of the body [3,4] . MRI is the cornerstone imaging evaluation for injuries to the brachial plexus [5] . MRI helps diagnose the injury and accurately identify the site of injury [5,6] . Injuries related to personal watercraft (PWC) accidents have long been recognized due to their increased use [7] .  \nBrachial plexus injuries after PWC accidents have been rarely reported. To the best of our knowledge, only one prior case has been reported in the literature. Sandri et al. described a patient with an injury to the brachial plexus after falling from a high-speed jet ski secondary to the fracture of both first ribs after the high-impact dive [8] . We present a patient who was riding a PWC when she was struck by an ocean wave and ejected backwards, causing injury to both brachial plexuses.  \nCase Presentation  \nA 38-year-old female was riding a PWC when she was struck by an ocean wave and ejected forcefully backwards. She remembered holding onto the handlebars as she initially fell. In the water, she immediately started complaining of severe cervical pain extending to her lower back, associated with numbness and tingling in her four extremities. The physical examination revealed an alert and oriented patient with intact deep pain and light touch sensation in all four extremities. The motor exam demonstrated bilateral upper extremity weakness. The hand grip and the triceps muscle were 4/5 bilaterally. Deltoid, biceps, and brachioradialis muscles were 1/5 on the left and 2/5 on the right.
