BIOLOGICAL CONSTANTS

Here are the results of the exams performed on October 5 th , 2006 at the LCL Laboratory in Paris

After having verified that her kidney function was normal  
I° - Evaluation of calcium metabolism

(VR : 25 to 49 mg/l)
(VR : 15 to 65 pg/ml)
(Optimal concentration: 20 to 50 ng/ml)

BONE DENSITOMETRY

Mrs. H.J. 78 y.o.
03-10-2006

BD (g/cm²) Right Hip BD (g/cm²) Left Hip
       
Neck 0,600 g/cm² Neck 0,515 g/cm²
Troch 0,484 g/cm² Troch 0,508 g/cm²
Inter 0,995 g/cm² Inter 0,911 g/cm²
Ward 0,416 g/cm² Ward 0,360 g/cm²
Total 0,800 g/cm² Total 0,764 g/cm²
       
      (Dr Jean Charles RUIZ)

We note that the left femur which was broken twice, operated on multiple times (twice near the hip and four times near the knee) has a total mineral bone density that is lower by 0.036 g/cm 2 ± 2% than the other femur - in other words a has a level of mineralization that is not very different from that of the unbroken femur.


BONE DENSITOMETRY

T-Score and Z-Score

  Right Hip Left Hip
  T-Score Z-Score T-Score Z-Score
Neck -2,5 -0,3 -3,4 -0,6
Ward -3,2 -0,3 -3,8 -0,2
Total -2,0 -0,2 -2,3 -0,2

We note that while Mrs. H.J., in spite of the two fractures of the same femur, a fracture of the wrist and a fracture of a rib, has a near-normal level of mineralization for a person her age in both the healthy femur (right) and the fractured femur (left).


EVOLUTION of the BD
(mg/cm²) from 1989 to 2006

 
1992: Substitute hormonal treatment 1993: graft of natural coral in the left femur

We note a regularly increasing mineralization since 1989 at the level of the neck of the femur, a quasi stable mineralization at the level of the greater trochanter. On the other hand, we note a regular decrease at the level of the Ward triangle. Neither of the two hips has received natural coral.


BIOLOGICAL BONE MARKERS
october 2006

 

OSTEOCALCIN: result technically verified from the same sample
CTX-CROSSLAPS: C terminal telopeptide of type I collagen
PIN1: N terminal propeptide of type I procollagen
Women: VR : 10 to 23 ng/ml
Women: VR : 0,10 to 0,32 ng/ml
Women: VR : 15 to 60 µg/l

Mrs. H.J has physiological bone resorption and bone mineralization that is above average.



THOUGHTS
Assessment 14 years after the natural coral graft

In the course of the first 18 months of the Substitute Hormonal Treatment
- Three fractures occurred.

Since the coral graft + Substitute Hormonal Treatment
- No fracture has occurred.
- The densitometry of the neck of the femur has increased (it has gone from 0,600 g/cm² to 0,750 g/cm²).
- The calcium level has normalized.
- Bone resorption is physiological.
- Bone remineralization is above average.

THOUGHTS :

 

Bringing 24g of calcium carbonate to the site increased the mineral level in the femur. The intracortical subperiosteal graft site is consistent with the experimental observations (8).

Supplying calcium to an “older person” - with low bone kinetics - is consistent with experimental observation (1,2,3).

Endocortical resorption (4,5,6) reduced the mechanical resistance of the bone. This is the reason for the subperiosteal intramedullar coral graft.

Lack of use of the muscles altered their functional properties. Using the muscles again quickly accelerated their recovery (9).
