Compound dislocation of the testis is a term coined by Alyea1 in 1929 to describe the traumatic extrusion of the testis from the scrotum through the skin. It is an accident of extreme rarity. However, there has been an increased frequency in the past decade, and further incidence may be expected owing to automobile and airplane accidents. The universal causative factor is a terrific blow to the scrotum countersustained by the pelvis.
