    Pharmacological

    • Patient continued the calcium and vitamin D supplementation
    • Following the TAHBSO, the patient was found to be an unsuitable candidate for hormone replacement therapy
    • Patient was started on Romosozumab therapy on the 25th April 2022
  • Follow Up
    • Upon completing one year of Romosozumab therapy, a BMD measurement was repeated on 29th May 2023, showing an improvement in T-scores to -2.2 at the lumbar spine and -1.3 at the total hip.
    • The patient was then transitioned to Alendronate.
    • Additionally, the bone and joint pain she had experienced for several years appeared to have resolved.
    • Functionally, the patient was able to start exercising in the gym again.

  • Summary

    The patient was under follow-up for intermittent joint pain*
    A BMD measurement was performed on 27th February 2021, prior to undergoing TAHBSO.
    The patient was started on calcium and vitamin D supplementation. Another BMD measurement was taken on 25th April 2022, one year after the TAHBSO, and Romosozumab therapy was initiated.
    A further BMD measurement was done after completing one year of Romosozumab therapy, on
    29th May 2023.
    BMD results improved, and the patient’s bone and joint pain resolved*

    • Spine BMD change: [(0.754 - 0.639) / 0.639] x 100% = 18%
    • Hip BMD change: [(0.699 - 0.653) / 0.653] x 100% = 7%

    *Kindly note that romosozumab is not indicated for pain relief of the bone or joints. Kindly refer to the local prescribing information for the approved indication of romosozumab.
