Viewing Osteoporotic Compression Fractures All Day

While working as a radiologist for 25 years, a large part of my day was spent reading X-rays of osteoporotic compression fractures of the spine, which was quite common.  These fractures typically involve the mid thoracic spine causing loss of height and curvature of the spine, and considerable pain.

Vertebroplasty for Compression Fracture - Barbaric?

Working in the hospital over the years, I saw many procedures come and go.  A procedure
called vertebroplasty, still in vogue, is used for treatment of compression fractures. This involves injecting glue into the collapsed vertebral body under X-Ray control.(1) Although the procedure may seem somewhat barbaric, it does provide pain relief and restores some height to the collapsed vertebral body. The vertebroplasty procedure was invented in 1984 by the French and introduced into the US by Mary Jensen MD.  The procedure is not for the light hearted because during the actual acrylic glue injection, the acrylic cement may flow into the epidural venous plexus leading to venous thrombosis or pulmonary embolus.(2) The more refined Kyphoplasty version involves inflation of a balloon device to expand the collapsed vertebral body just prior to injection of cement into the cavity. The procedure is quite good at providing some form of pain relief from the compression fractures.

Vertebroplasty Procedure Discredited

In 2009, two studies showed Vertebroplasty had no merit, producing results no better than a sham operation.  The authors concluded the procedure was without merit and should be abandoned.  The medical community ignored these studies, and numbers of procedures actually increased.(16-18) 

Prevention Makes More Sense

On the surface, it might appear callous for the medical system to wait years until thousands of women develop severe osteoporosis with compression fractures, and then intervene with glue injections.  Perhaps some form of prevention would make more sense.  The usual preventive recommendation to take calcium tablets apparently was not effective for these women presenting with osteoporotic compression fractures.  Perhaps the best preventive plan can be found in Russell Jaffe’s article
,  Acid-Alkaline Balance and its Effect on Bone Health.(3)  Russell Jaffe MD is a charming and humorous fellow who informed our small group of docs at his medical seminar that in the old days he ran a lab at the NIH, and was actually offered the job of Assistant Surgeon General, but he declined the offer after trying it for a day.  He is also the founder of a supplement company called Perque.(15)

Excess Acid in the American Diet Causes Osteoporosis

According to Dr. Jaffe's article, excess acid production from the American diet causes the chronic calcium loss leading to osteoporosis.(3)  The calcium is pulled away from the bones, and used up as a buffering agent for the acids which can then be excreted in the urine.  The solution is to alkalinize the diet, and with the help of alkaline food charts, and pH test strips along with the usual calcium and vitamin supplements, osteoporosis can be arrested and gradually reversed in a process which may take years. I would add that a bio-identical hormone program is also useful for preventing and reversing osteoporosis.

Bisphosphonate Drugs and Toulouse Lautrec's Genetic Bone Disease

For the impatient ones who wish to see a prompt increase in bone density, the FDA approved the bisphosphonate drug Fosamax (alondronate) which was first introduced in 1995. Merck made 3.2 Billion on 22 million Fosamax prescriptions in 2006.  A major drug study, (FIT) the Fracture Intervention Trial, showed lower fracture rates in the drug group.(4)  And it is true that the bisphosphonate drugs will reward the user with a prompt increase in bone density.  The main question remains however, how strong is the bone with the increased density? This is an important question because we know from studies of Toulouse Lautrec that his increased bone density was not stronger, in fact his bones were much weaker leading to spontaneous fracture and jaw necrosis.  This is explained below.

short stature from pycnodysostosis.

Genetic Bone Disease Duplicates Action of Fosamax

What could fosamax (alondronate) have in common with Toulouse Lautrec, the famous French Impressionist artist?  One day, Toulouse Lautrec's name came up in conversation, and we puzzled over the cause of Lautrec's short stature.  After looking up the question on the internet, we discovered that Toulouse Lautrec’s parents were first cousins giving Toulouse the autosomal recessive genetic disease, pycnodysostosis, which means dense bones. I had seen X-Rays of this bone disease in text books while studying for the radiology board exams, but I have never seen it in actual practice. 

Dr. Gelb 
found Toulouse Lautrec's dense bone disease was caused by a genetic defect in cathepsin K, a protease enzyme of the osteoclast cells responsible for removing and remodeling bone.(5)(6)  Osteoclast cells are bone cells involved in resorption and remodeling of bone. In this disease, the genetically abnormal bone is very dense on xrays, and yet looking under microscopic examination, one sees profound deterioration in trabecular architecture and lamellar arrangement. This is presumably the reason for spontaneous fracture and jaw necrosis which occurs in Lautrec's genetic bone disease, and also occurs as an adverse side effect of the bisphosphonate drugs.(7

This osteoclast dysfunction and resulting bone fragility explains why Toulouse had spontaneous fractures of both mid femurs at the age of 12 and 14. The mid-femur fractures never healed properly.  The non-healing mid femur fractures caused Toulouse Lautrec to have short stature, attaining a final height of only four and a half feet.(8)

Bisphosphonate Mechanism of Action - Same as Lautrec's Defect

Bisphosphonate drugs (fosamax and actonel) are taken up by osteoclasts, causing disruption of osteoclast activity.  The osteoclasts are bone cells involved in bone resorption and remodeling.  This loss of the osteoclast activity inhibits bone resorption and bone remodeling, tasks otherwise performed by the osteoclasts
.(9)  Thus, the bisphosphonate drugs produce a chemical disruption of osteoclast activity same as the genetic disease of Toulouse Lautrec.  The bisphosphonate drugs also produce the same adverse side effects, namely jaw necrosis and spontaneous fracture.

Questions About Long Term Safety of Bisphosphonates

The conventional medical test for bone density is the DEXA bone scan. And, indeed DEXA bone scanning does confirm that bisphoshonate drug treatment increases bone density, and studies such as the FIT (Fracture Intervention Trial) report drug treatments reduce fracture rates in severly osteoporotic women over the short term.  However, Susan Ott, MD  raises questions about the long term safety of bisphosphonates.(10)  Although the bisphosphonate drugs appear to have short term benefits, Dr. Susan Ott speculates that over the long term, after 5 years of use, the drugs cause severe suppression of bone formation, and negative effects such as microdamage and brittleness.

Reports of Spontaneous Fractures

Clip_image002 Jennifer P. Schneider, MD, PhD reports a 59-year old previously healthy woman on long-term alendronate.(11) While on a subway train in New York City one morning, the train jolted, and the woman shifted all her weight to one leg, felt a bone snap, and fell to the floor, suffering a spontaneous mid -femur fracture (see right image). In the months following, it became clear that the fracture was not uniting.

Schneider speculates that increased bone density from the bisphosphonate drug does not necessarily equate with good bone quality. By decreasing osteoclast activity and bone resorption, and therefore bone formation as well, microdamage, and brittle bone may result in fractures.(11)

Odvina reports on a series of 9 patients who suffered spontanous fracture while on fosamax (alendonate). Five of the nine cases were spontaneous mid femur fractures.(12)  Two had bilateral mid femur fractures just like those sustained by Toulouse Lautrec. Six of the fractures showed delayed or absent fracture healing.  Histomorphometric analysis of the cancellous bone showed markedly suppressed bone formation, and Odvina raised the possibility that severe suppression of  bone turnover could develop during long-term fosamax (alendronate) therapy, resulting in increased susceptibility and delayed healing of fractures.

Dimitrakopoulos report on 11 patients presenting with necrosis of the jaw, claiming this to be a new complication of bisphosphonate therapy administration, i.e. osteonecrosis of jaws.(13) He advised clinicians to reconsider the merits of the rampant use of bisphosphonates. Osteonecrosis of the jaw is a common finding in pycnodysostosis. The bisphosphonates recreate the same clinical profile of spontaneous mid femur fractures, failure of bone healing and jaw necrosis which tormented Toulouse Lautrec.

In spite of these widely adverse effects of bisphosphonates, there are four more drugs in clinical trials specifically designed to inhibit cathepsin K, the enzyme defect in Lautrec's genetic bone disease.(14)  FDA approval for use in osteoporosis treatment is expected. Excuse me here, but perhaps this thinking needs re-evaluation. In essence, these drugs are creating a population of women with Toulouse Lautrec’s bone disease.

no bull shit fosamaxIronically, women who sustain fractures while on Fosamax are told by their docs that the fractures are due to the underlying osteoporosis, not the drug.  For a recent example that I know of, a 60 year old female sustained a fractured elbow after minor trauma at home in the kitchen. She claims that, if not for the biphosphate drug, her fracture would have been much worse. When patients continue to fracture while on the bisphosphonate drugs, the medical system tends to blame it on the underlying osteoporosis, not the drug.  Sound familiar? 


The obvious conclusion is that this entire class of bisphosphonate drugs should be banned, and I predict that they will be banned within the next few years.  Remember that you read it here first.

Cathepsin K is a lysosomal cysteine cathepsin predominantly located in osteoclasts and is the major enzyme involved in bone resorption. The first evidence for this role came from a genetic study on pycnodysostosis, a rare genetic disorder associated with severe defects in bone growth, which revealed that an inactivating mutation in the gene encoding cathepsin K is a causative factor.
