A Lesson in Causation

Filed under: Uncategorized — Tags: — stemcelldoc @ 2:34 pm

Causation: the relation of cause to effect.

Motor vehicle accidents cause  significant amounts of injury.  Structures commonly injured include cervical facets, lumbar intervertebral discs and sacro-iliac joints(SI).

What and who caused the pain is often a point of contention which  led some patients to the pursue legal action.  Thousands of dollars are spent in accident reconstruction, analysis of vector speeds and inspection and documentation of damage sustained by vehicles involved.

The concept  of causation is not taught in medical school and as a rule is not well understood by physicians.

Centeno and Freeman had recently simplified the process in their recent publication:  A Systematic Approach to Clinical Determinations of Causation.

Three key questions provide a systematic framework:

1) Biologic Plausibility:  Can a motor vehicle injury of any severity cause such an injury?

2) Temporal Association:  Did the motor vehicle accident precede the symptoms?

3)  Lack of likely alternative explanations:  Is there another reason or event that could have caused the symptoms.

Thank you gentlemen.

The Regenexx Procedure makes Headlines

The Regenexx procedure has once again made the headlines.

The Regenexx procedure allows patients to use their own bone marrow derived stem cells for common orthopedic conditions.

It’s a valid medical procedure right now,” said Dr. Christopher J. Centeno, medical director of the Centeno-Schultz Integrative Pain Management Clinic.

For many patients it can mean avoiding surgery and months of rehabilitation with a procedure that just requires a few needles of treatment.

Stem cell function continues to be a topic of intense research.  Stem cells play a key role in cellular repair.

“The body is in constant need of repairing itself,” Centeno noted. What’s more amazing than the differentiation, he said, is the ability of the stem cells to direct other cells and their traffic needed to complete the healing, or what he calls the “Bob the Builder” factor.
