THE HISTORY & DEVELOPMENT OF THE EXETER™ HIP
2ND EDITION

FOREWORD:

The first edition of this short monograph was published in January, 1997. At that time, survivorship studies of the original polished Exeter stems were available to the 19th year of follow-up, and experience with the Exeter Universal stems extended to only 8.5 years, both in primary interventions and in revision surgery in association with impaction grafting.

By late 2004, a new edition was called for and was published in early 2005. Survivorship data on the original  polished stems up to the 33rd year of follow up was by then available and experience with the Exeter Universal stems exceeded 16 years in primary interventions and in revision surgery in association with impaction grafting. This second edition is now out of print and the present version of the monograph is

a reprint as from January 2006.

In this reprinted version of the second edition, the opportunity has been taken to update some of the data with respect to the original polished stems, in the light of further follow-up information that emerged during

2005, as follows:

a. 2 patients died towards the end of the year 2003 and one other died in year 31 (these deaths were not known to the Hip Unit at the Princess Elizabeth Orthopaedic Centre until late 2005). This leaves in toto 33 hips in 26 living patients.

b. In the first printing of the second edition of the monograph, it was reported that 15 stems had been revised for aseptic loosening in toto. However, during a study looking for common factors in all the femoral failures from aseptic loosening, it emerged that 1 hip had been incorrectly recorded as being a failure. This case had been operated on for cup loosening in the presence of a soundly fixed stem that was removed to enhance the exposure of the socket and then a new stem was inserted using the using cement in cement technique.

The total number of failures from aseptic stem stem loosening is thus 14 and not 15.

These changes have been incorporated into the text and survivorship curves of this reprinted version of the monograph.
