Many throws in handball are done similar to the ratchet-style hits of volleyball - where deceleration does not cross the midline and heavily biases the glenohumeral joint - this predisposes to local stress instead of shared stress.
Reduced total glenohumeral rotation has been identified as a risk factor among elite male handball players. (Clarsen et al, 2014).
