One hundred cases of the Charnley low-friction arthroplasties using shorter (75-110 mm) than standard length stems, both in primary and revision surgery were reviewed. The average follow up was five years and three months. Eleven had cortical thickening that could be attributed to the predicted increase in the stresses within the femoral cortex. There were no cases of cortical thickening when the stem was 100 mm or longer. One stem in the 80-84 mm group was revised for loosening. The findings suggest that other than cortical thickening, which has not progressed during the period of the follow-up, there is no need to fear the use of shorter stems if indicated for technical reasons and provided good stem fixation can be achieved.
