Abstract
The implanting of a hip endoprosthesis changes the mechanical loading in a hip. The changing in loading causes bone remodeling. The loss of loading leads to bone atrophy, whereas an increase in loading leads to hypertrophy of the bones.We investigated the relationship between the clinical result and change in periprosthetic bone mineral density. The Harris hip score was used to measure the clinical outcome. The dual photon densitometry method was used to measure periprosthetic bone mineral density. The obtained results showed that a loss in bone mass around the hip endoprosthesis does not affect the clinical outcome of the operation. Bone hypertrophy has a positive effect on the clinical outcome. The patient’s age, sex and body weight in the investigated population did not have an negative impact on functional status. The time passing from the operation to measuring had a negative impact on the functional status.
