UPPER EXTREMITY.
Gunshot Fracture of the Ulna.
The course of the bullet was in an anteroposterior direction at a high velocity of short range, which, imparting its energy to the fragments, drove some of them through the tissues as “secondary missiles” and caused a laceration of the wound to exist.
The longitudinal fragmentation and splitting indicates a considerable energy of the projectile, which may have been deflected, as its long axis was turned somewhat from the trajectory at the time of impact.
The emergency treatment is antiseptic dressing and splint immobilization.
The subsequent treatment is conservative with the removal of detached fragments and with control of infection as the course indicates.
