Abstract
1. The operation of pseudarthrosis of the hip joint is described and the results are assessed in ninety-three patients.
2. The result was good in eighty-three cases and poor in seven cases. Three patients died as a result of the operation.
3. Pseudarthrosis is the most satisfactory and the most reliable operation: 1) in ankvlosing spondylitis, and 2) in patients over sixty years of age with disabling osteoarthritis.
4. The more formidable operation of cup arthoplasty may prove to be superior in younger patients with osteoarthritis.
