Peter Alexander Ring was born in London in 1922. After his education at University College in London he continued his orthopedic training in a variety of well-known orthopedic centers in and around London. As the Laming Evans Senior Orthopaedic Research Fellow (1956-1959), he studied epiphyseal growth under a variety of conditions and applied the information obtained to the clinical problem of leg length equalization in poliomyelitis patients. In 1959, he appointed surgeon in charge of the Joint Replacement Unit of the Dorking Hospital in Surrey, where he has remained ever since. He rapidly became dissatisfied with the results obtained by using the Austin Moore prosthesis without an acetabular prosthesis in patients with osteoarthritis. He did not bellieve that the use of methylmethacrylate would provide adequate fixation of components over the long term and sought another solution to the problem. His approach was to devise methods of cementless fixation of his two metal components. The results of his work were described in the following paper. The original design was used in the first 25 patients beginning in 1964. A different design featuring a modified cup was used in the remaining 155 patients.
