请高手评论一下我过去15年骨密度的变化

33岁生完孩子后严重骨质疏松，不明原因的lower back L1 - L2压缩性骨折。2023年一脚踩空导致脚髁骨折。

作为高危人群，从此以后，每隔几年就做一次骨密度检查。底下汇总了大多数的检查结果，请高手评论一下。

spine injury age 33. Spine films 2010 show compression fractures of L1 and L2.

2024 -  49-year-old Asian woman with early menopause

Ankle fracture recorded in 2023; 2 falls this past year.

• Lumbar site [T score -0.5]. Values have fluctuated over the past 14 year interval but remain above baseline.
• Left femoral neck [T score -0.8]. Over the past 5 year interval there has been a 10% decline at this site.

2022 - 47-year-old Asian female with early menopause

• L1-4: 1.18 g square centimeter, T score 0
• Left Femoral neck: 0.968 g square centimeter, T score -0.5
• Total hip: 1.033 g square centimeter, T score 0.2

There is normal bone density at both measurement sites.  There has been a 4.8% decrease at the spine and a 5.8% decrease at the femoral neck since the previous evaluation in March 2019. Assessment for and
 amelioration of any secondary causes of bone loss is suggested. 

2019 - 44 years old Female

• Within expected range for age based on the lowest Z- Score (0.4) at the lumbar spine

2012 - 37 year old female

• LUMBAR SPINE: L1-L4. 99% of reference.
• TOTAL HIP: Left side. 100% of reference.
• LEFT FEMORAL NECK: 102% of reference, with a T score (variation in st.dev.) of +0.2.

Spine: an interval increase of 14%.
Left femoral neck: an interval increase of 5%.

2010 - 35 year old female

• No significant interval change. Minimal anterior wedging of the L1 and L2 vertebral bodies. Alignment well maintained with flexion and extension. No other findings.

2009 - 34 year old female

• Low Bone Density; L1-L2 compression fracture. Reason unknown
