Brief Summary
The study is a cohort study comprising 136 patients with osteoporosis stopping treatment with alendronate. The study will contribute with new knowledge about biochemical markers of bone turnover as predictors of bone loss after stopping treatment with alendronate.

Outcome Measures
Primary Outcomes (1)
If Carboxy-terminal Collagen Crosslinks (CTX) Three and Six Months After Stopping Alendronate Predicted TH BMD (Total Hip BMD) Loss Above the Least Significant Change at Month 12 at the Individual Level.
We constructed receiver operating characteristic (ROC) curves to evaluate if carboxy-terminal collagen crosslinks (CTX) three and six months after stopping alendronate predicted TH BMD loss above the least significant change (LSC) at month 12 at the individual level.
Baseline and one year after baseline
Secondary Outcomes (4)
Percent Change in Bone Turnover Markers Measured Three and Six Months After Stopping Alendronate Treatment and BMD After One and Two Years
one and two years after baseline
Number of Participants in Which CTX Increased Above the Least Significant Change
From baseline to month 24
The Number of Participants Who Lost BMD Beyond the Least Significant Change (LSC) at the Lumbar Spine and Total Hip.
from baseline to month 24
If Baseline Bone Turnover Markers at the Time of Alendronate Discontinuation Predict Changes in BMD After One and Two Years.
Changes in TH BMD after one and two years.
Interventions
136 patients with osteoporosis stopping treatment with alendronate.
