Dick L. Johnson v. Boise Cascade

On August 18, 1964, respondent was employed by Boise Cascade Corporation, one of the appellants herein, at Emmett, Idaho.
While stacking lumber, the respondent twisted his back, experiencing immediate pain. The next day respondent visited Wm. B.
Jewell, M.D., of Emmett, who prescribed conservative treatment and referred respondent to Jerome K. Burton, M.D., an orthopedic
surgeon practicing in Boise, Idaho. Dr. Burton determined that respondent had suffered an upper back sprain and referred him
back to Dr. Jewell for further conservative treatment. Thereafter respondent made reasonable progress until January 17, 1965,
at which time he had a recurrence of the back pain and was hospitalized. He was put in traction and was referred to Edward
Kiefer, M.D., a neurosurgeon of Boise, for consultation. On February 2, 1965 a notice of injury and claim for compensation
was filed with the Industrial Accident Board. Dr. Kiefer examined the respondent and made a report of his findings on February 15, 1965. At that time it was the doctor's
impression that respondent had a possible lumbar disc protrusion at the L4-5 level. Dr. Kiefer recommended a myelogram. The
myelogram verified the doctor's impression and on February 22, 1965, the respondent was subjected to a lumbar laminectomy
and a disc protrusion at the L4-5 interspace was removed.
