Introduction

All major national records show a regular annual increase in the number of total hip replacements (THRs). [1-4]

Anticipating complications and improving outcomes in the short, medium or long term have been the principal concerns of orthopaedic surgeons for several decades. The importance of acetabular positioning has long been recognized as a determining factor for mobility [5], osteolysis and wear [6-8], the risk of dislocation [9] and the risk of impingement [10].

Cementless fixation of an acetabular cup demands rigorous preparation of the acetabular socket with drills or ‘reamers’ before placement of the final implant. Competence in reaming the acetabular socket to achieve the correct diameter and the optimal position should allow the acetabular cup to be placed as close as possible to the planned ‘target’, or with a degree of tolerance that should avoid any detrimental impact on mobility, stability or fixation.

The surgeon should pay particular attention to the tool used for reaming.

A recent survey of more than 130 French surgeons, who are members of the Société Française de Chirurgie de la Hanche et du Genou [SFHG, French Society of Hip and Knee Surgery] and experts in prosthetic hip surgery, enabled us to take stock of current reaming practices during...
