Hafer v. Anaconda Aluminum Company

Hafer was an iron worker for the Anaconda Aluminum Company in Columbia Falls, Montana. He was involved in an industrial accident on June 17, 1977, in which he sustained a displaced fracture of his left elbow. As a result of the injury, a silastic prosthesis was implanted in his elbow on August 21, 1978. Hafer now suffers from restricted mobility of his elbow and his orthopedic surgeon has rated his permanent partial impairment as 20 percent of his left upper extremity. The manufacturer of the prosthesis disclaims its effectiveness for persons who engage in strenuous physical activity.
