Blunt rupture of the biceps brachii muscle - The "parachute injury" in a wake surfer - A case report.

Case: A 40-year-old man fell while wake surfing and his left arm got tangled in the rope. This caused a closed complete rupture of the M. biceps brachii. A primary muscle suture led to unrestricted function and excellent patient satisfaction after two years.

Conclusions: The mentioned muscle rupture is a rare injury mainly described for paratroopers. As it has also been described for wakeboarding, this is the first description in wake surfing. Whereas in wakeboarding mainly experts are at risk during jumps, in wake surfing beginners are in danger and must be advised accordingly. Generally, the muscle suture leads to excellent function in these patients.
