    Early radiological observations may predict the long-term survival of femoral hip rpostheses J Bone Joint Surg 79-B: 583-589,1997-

    -for individual prosthesies , migration of <2mm and the absence of an RLL of ¡Â 2mm at two years predict a 6 % chance of revision over approximately ten years. If either 2mm of migration or an RLL of 2mm is present, the chance of revision rise to 27 %, and if both radiological signs are present they are 50 %. If at five years a lytic lesion has developed, whatever the situation at two years, there is approximately a 50 % chance of failure in the following five years

    7.Early loosening of the femoral component at the cement-prosthesis interface after THR --Mohler CG et al : JBJS,77-A ,1315,1995. mechanical fatigue failure of cement was major cause of aseptic loosening of femoral component--------ÇØ°áÃ¥À¸·Î- CoCr stem, cobra-shaped proximal part stem, and slight longer stem-À» Iowa ´ëÇп¡¼­ °³¹ß

    early loosening- was average 5 yrs radiolucent zone 1 of Gruen many of stem rotated in the cement : no gross fracture of the cement mantle were apparent Autopsy studies- long-term failure of fixation of cemented femoral component is mechanical nature, with fracture of the cement and debonding of the component from the cement initiating the loosening process

    Debonding is initial factor in the loosening of the cemented stem- methods of improve bond between prosthesis and the cement - txtured finished on the stem and precoating with PMMA so called interfacial porosity is not affected by such factors centrifugation or surface finish and may adversely influence bonding the cement to the implant Mechanical study demonstrated that micromotion is increased at the cement- prosthesis interface compared with that at the bone-cement interface

    Recommend with a more rectangular stem geometry and a polished surface finish to modify Iowa stem
