title: [Early results of densitometry around the cementless stem of the Parhofer-Mönch hip endoprosthesis].
abstract: Fifty-three patients with unilateral hip arthritis (31 females, 22 males) aged from 29 to 66 years (mean 52.1 years) after total hip replacement with cementless Parhofer-Mönch endoprosthesis underwent densitometry. The content (BMC) and mineral density (BMD) of calcium within proximal end of the femur was evaluated at 8-12 days postoperatively and at 6, 12 and 18 months follow-up. Early results show various mineral changes in Gruen zones around the stem. The greatest BMC and BMD decrease was found at 6 months follow-up in zones 1 and 7 as well as 2 and 6. The BMC and BMD tendency to decrease gradually ceased and slightly positive values were found in zone 3, 4 and 5 at the final evaluation.
