This study of 9 and 10 years results of low-friction arthroplasty concerns operations performed from November 1962, when high density polyethylene for the hip socket was first introduced, to December 1963. This same series has been reported previously for 7 to 8 year results' but because we found it impossible to identify all the cases in the previous study it was considered advisable to go back to the original source material and, with a view to future studies of the ultimate fate of these patients, to identify all the material by: the initials of the name; the hospital number; the sex; and the age at time of operation. The protocols of all the hips in this study identified in this way are recorded in Table I.
