Right Femur Total 17/06/2008 34.4 0.867 g/cm² -1.4 -1.4 - -

Assessment:

  • The Spine L1-L4 BMD is normal.
  • The Left Femur Neck BMD is in the osteopenic range. Relative fracture risk is about 2.
  • The Left Femur Total BMD is in the osteopenic range. Relative fracture risk is about 2.
  • The Right Femur Neck BMD is in the osteopenic range. Relative fracture risk is about 2.
  • The Right Femur Total BMD is in the osteopenic range. Relative fracture risk is about 2.

COMMENT

Osteopenia on measured BMD. The estimated 10-year probability of fracture based on present age, gender and measured BMD is less than 10%. This absolute fracture risk remains low. A follow-up assessment may be considered in 2 to 3 years to monitor the trend in BMD.

Thank you for your referral. Dr Peter Ng 17/06/2008

Note:
WHO classification of osteoporosis (WHO Technical Report Series 1994: 843)
- Normal: T-score equal to -1.0 s.d. or higher
- Osteopenia: T-score  between -1.0 and -2.5 s.d.
- Osteoporosis: T-score equal to -2.5 s.d. or lower
- Severe/Established osteoporosis: Osteoporosis with one or more fragility fracture.
T-score: The number of s.d. from the mean BMD for a gender-matched young adult population.
Z-score: The number of s.d. from the mean BMD for an age-, weight- and gender-matched population.
