Abstract
Fear of dislocation is one of the reasons why the very small prosthetic femoral head (22.25-mm diameter) has not become universally popular. But our dislocation rate at Wrightington even prior to 1966 did not average more than about 1% whereas a dislocation rate of 5% with a 41-mm-diameter head was reported by McKee and Chen(55) in their first 100 cases. Dislocation of Thompson and Moore prostheses of large diameter are also not uncommon. Therefore the size of a femoral head in itself is not the essential factor in susceptibility to dislocation.
