Abstract
High dynamic bending and torsional stresses may give rise to fatigue and stress corrosion failures of prosthetic stems of total hip joint devices in case of loosening, which up till now remains one of the major problems of hip joint replacement. A safety limit of 3–5 million cycles has been settled upon the basis of clinical experience with loosened femoral components /1/ and should contribute to preventing the removal of distal stem fragments involving aggravated conditions to reoperation.
