“There are lies, damn lies, and statistics…”

                                                         -Mark Twain

At Regenexx, unlike everyone else offering stem cells, we perform the back-end basic research to improve what we do. With the opening of our 2nd lab in our Colorado facility (Regenexx Research and Discovery Lab), we’ve been hard at work finding out new ways to help heal orthopedic injuries using stem cells and platelets. One project we began last year as a pilot will be completing in the next few months and closely guessing the outcome of this particular orthopedic stem cell research project could provide you with a $2500 credit towards a Regenexx stem cell procedure at our Colorado office.

We’ve been told for many years that giving middle-aged and elderly men testosterone to treat what’s called Andropause would most certainly help their stem cells. However, after looking through the published literature, it turns out the certainly of some of our colleagues is what I call a WAG (Wild A$$ GUESS), in that no research has ever been conducted with patients looking at stem cell production before and after low T was fixed. So we began an IRB approved research project. We first tested the stem cells of 4 men both before and after a simple hormone replacement program lasting 3 months. While we had no idea of what we would find, on average, we did see that the men produced about double the number of stem cells after their hormones were fixed and that these stem cells were more robust and less likely to be hurt by catabolic (read bad) cytokines (read chemicals) that could be found inside an arthritic joint. However, 4 samples isn’t enough to hang your hat on, so we moved to the next step of recruiting and treating an additional 16 men for a total of 20. This is the second phase of the research that will soon be concluding.

Now here comes the fun part. Use Twitter to tweet your stem cell guess to my Twitter account (@CCentenoMD), or send us a message through Facebook (https://www.facebook.com/Regenexx) in terms of a percentage of stem cells above (or below) baseline to the tenths place. So for example, if you thought the larger group of patients would see roughly a doubling of stem cells, then you might go with 100.5% more stem cells. If you thought that the stem cell count will go down by about a quarter, then you would tweet -25.2% stem cells. When the project is done in the next 1-2 months, I will reveal the winner. In the meantime, taking a guess on how those stem cells will perform in our lab may be a great way to ease your wallet!

FYI, I will also have our biostatistician (who performs research on the clinical outcomes in the registry) test Sir Frances Galton’s theory of regression toward the mean. Galton was a keen observer of everything. In 1906, while visiting a livestock fair, he stumbled upon an intriguing contest. An ox was on display, and the villagers were invited to guess the animal’s weight after it was slaughtered and dressed. Nearly 800 participated, but not one person hit the exact mark: 1,198 pounds. He asked the judges for all of the guesses to perform a mathematical experiment. He then went home and calculated the mean of the entries, thinking at first that the crowd would be dumb and cattle experts who had guessed would come the closest to guessing the real weight. However, he was astonished to find that the statistical mean of the entries at 1,197 pounds, was even more accurate than any one individual guess. In essence the crowd was smarter than any expert. This math experiment has since been memorialized by being conducted again and again in college statistics courses all over the world, usually with guessing the number of jelly beans in a big jar. Will the wisdom of a crowd of Regenexx blog readers get it right? This problem is bit different than the Ox, as I’m asking the group to guess on something without any physical evidence before them other than the fact that the stem cell count about doubled in the first experiment. Will the statistical mean or randomness prevail? Stay tuned…

Regenerative procedures are commonly used to treat musculoskelatal trauma, overuse injuries, and degenerative issues, including failed surgeries.
Select Your Problem Area
Shoulder

Shoulder

Many Shoulder and Rotator Cuff injuries are good candidates for regenerative treatments. Before considering shoulder arthroscopy or shoulder replacement, consider an evaluation of your condition with a regenerative treatment specialist.

  • Rotator Cuff Tears and Tendinitis
  • Shoulder Instability
  • SLAP Tear / Labral Tears
  • Shoulder Arthritis
  • Other Degenerative Conditions & Overuse Injuries

Cervical Spine

Spine

Many spine injuries and degenerative conditions are good candidates for regenerative treatments and there are a number of studies showing promising results in treating a wide range of spine problems. Spine surgery should be a last resort for anyone, due to the cascade of negative effects it can have on the areas surrounding the surgery. And epidural steroid injections are problematic due to their long-term negative impact on bone density.

  • Herniated, Bulging, Protruding Discs
  • Degenerative Disc Disease
  • SI Joint Syndrome
  • Sciatica
  • Pinched Nerves and General Back Pain
  • And more

Knee

Knees

Knees are the target of many common sports injuries. Sadly, they are also the target of a number of surgeries that research has frequently shown to be ineffective or minimally effective. Knee arthritis can also be a common cause for aging athletes to abandon the sports and activities they love. Regenerative procedures can be used to treat a wide range of knee injuries and conditions. They can even be used to reduce pain and delay knee replacement for more severe arthritis.

  • Knee Meniscus Tears
  • Knee ACL Tears
  • Knee Instability
  • Knee Osteoarthritis
  • Other Knee Ligaments / Tendons & Overuse Injuries
  • And more

Hand & Wrist

Hand & Wrist

Hand and wrist injuries and arthritis, carpal tunnel syndrome, and conditions relating to overuse of the thumb, are good candidates for regenerative treatments. Before considering surgery, consider an evaluation of your condition with a regenerative treatment specialist.
  • Hand and Wrist Arthritis
  • Carpal Tunnel Syndrome
  • Trigger Finger
  • Thumb Arthritis (Basal Joint, CMC, Gamer’s Thumb, Texting Thumb)
  • Other conditions that cause pain

Elbow

Elbow

Most injuries of the elbow’s tendons and ligaments, as well as arthritis, can be treated non-surgically with regenerative procedures.

  • Golfer’s elbow & Tennis elbow
  • Arthritis
  • Ulnar collateral ligament wear (common in baseball pitchers)
  • And more

Hip

Hip

Hip injuries and degenerative conditions become more common with age. Do to the nature of the joint, it’s not quite as easy to injure as a knee, but it can take a beating and pain often develops over time. Whether a hip condition is acute or degenerative, regenerative procedures can help reduce pain and may help heal injured tissue, without the complications of invasive surgical hip procedures.

  • Labral Tear
  • Hip Arthritis
  • Hip Bursitis
  • Hip Sprain, Tendonitis or Inflammation
  • Hip Instability

Foot & Ankle

Foot & Ankle

Foot and ankle injuries are common in athletes. These injuries can often benefit from non-surgical regenerative treatments. Before considering surgery, consider an evaluation of your condition with a regenerative treatment specialist.
  • Ankle Arthritis
  • Plantar fasciitis
  • Ligament sprains or tears
  • Other conditions that cause pain
