What are your femur readings? Did you have a TBS reading, that was make a huge difference in how you approach your situation. TBS looks at bone quality. Dexa is prone to misread with any bone abnormality so the TBS helps with interpretation.

Good news, it looks like this is just in your spine, and the spine has the ability to change quickly for the better. The femoral area takes longer to change just because of the nature of the bone.
You have options:
1. Osteoporosis drugs
2. BHRT/HRT
3. Strontium citrate which is a unique intervention somewhere between supplement and medicine
4. or a stronger combo of BHRT and strontium citrate or even adding BHRT/HRT to an osteoporosis drug regime

The options have different safety profiles and side effects. Plus, many of the osteoporosis drugs have a time minimum and may not be begun and stopped, easily.
Many people start with BHRT/HRT, and then add strontium citrate after or in addition to BHRT/HRT . This is influenced by their medical history and test results. Mainly, because SCitrate and BHRT/HRT are easily started and stopped compared to most osteoporosis drugs and may have fewer side effects. So this is just a conservative progession.

What you decide to take will depend a lot on you and with what you feel comfortable. Consult with your doctor and be sure to do your own research so you are part of the decision. Whatever your decision you should have good results; osteoporosis treatment is much better now than when your mother had osteoporosis.

I am a strontium citrate/BHRT user. MY osteoporosis was in my femoral area. I am now in normal bone density with normal bone quality.

Here are some posts about osteoporosis drugs, BHRT/HRT and strontium citrate.
