Wisely planned and skillfully executed operations for bone block at joints often result in greatly increased mechanical usefulness and in relief of pain. It is questioned whether this is frequently the outcome of operations for bone block at the hip joint. Of the two cases analyzed, the one for abduction block and for the relief of pain, the pain was relieved and a total of 39 degrees more motion was obtained, but there was an increase in shortening and 23 degrees less flexion; and the other case for adduction block and for relief of pain, resulted in a total increase in motions of 135 degrees and a very doubtful relief of pain. In both, the specific bone block sought was permanently removed and it is to be noted that both were complicated by conditions unforeseen-the man by removing his plaster dressing on the second day and thus causing a loosening of his osteotomized fragments with bad displacements, and the woman in that a neurotic habit prevents the proper judging of the subjective result of pain.
