[Mineralization of the Skeleton (DEXA) during Revision Surgery of the Hip Joint.].
The authors focus attention on the quality of osseous tissue in patients with revisions of TEP of the hip joint. They evaluate the quality of the osseous tissue indirectly, based on densitometric examination DEXA (DPX) using an apparatus LUNAR DPX L. They used software for whole body assessment. Measurements in 53 patients (33 women and 20 men), mean age of women 65 years, of the men 68 years, with an average period of 11 years (1-15 years) since the primary implantation revealed the following results. All patients have a reduced bone density of the pelvis and lower extremities. In men the density is lowest in the lower extremities - BMD 1.27 g/cm2 which corresponds to 91% age of the corresponding healthy population. The Z score is -1.31. In women the authors found a more marked reduction of the bone density than in men. The greatest decalcification was found in the lower extremities, BMD 0.96 g/cm2, which corresponds to 89% age of the corresponding population. The Z score is -1.57. The pelvis had a BMD of 0.98, i.e. 94% of the normal value, the Z score is -0.68. Based on these results the authors recommend to pay attention to improvement of the osseous tissue during revisions of TEP of the hip joint by dietary measures, lifestyle, pharmacological means and exercise. Key words: revisions of TEP of the hip joint, osteoporosis, densitometry, DEXA, DPX.
