Recent studies have shown that the order in which we use osteoporosis medications matters.  Traditionally most docs have used Antirsorptives first to preserve bone.  All osteoporosis medications except one are Antiresorptives.  Only when that failed, would they consider the Anabolic medication, Forteo, to build new bone.

As a practicing orthopedic surgeon, I started treating osteoporosis in the worst of my fracture patients.  It was obvious that they needed to build bone first since there was very little bone to preserve.  Therefore, I usually started with the Anabolic, Forteo.  Once I had built up the bone, I preserved that improved bone with an Antiresorptive osteoporosis medication.

As the National and International Osteoporosis Foundations, (NOF and IOF)  are now focusing on preventing second fractures, many more practioners are treating patients with one or more fractures.  They are facing the dillema of how to prevent fractures in bone that is not good enough.  None of the Antiresorptives work as well in patients with multiple fractures as they do in patients who have not yet fractured.

This year studies have shown that using Forteo after an Antiresorptive usually results in Forteo taking several months to overcome the previous slowing of bone turnover,  Therefore, 2 years of Forteo results in less improvement when used AFTER the Antiresorptives tested, than we normally see in a patient who uses Forteo first.

At NOF and IOF this year speakers suggested that we change our approach.  They suggested using an Anabolic first, and an Antiresorptive second should be the standard sequence for best results.

Would you rather only trying to preserve your bones after they have proven insufficient in multiple fractures?  Or would you want to improve your bone first, and then prserve that improved bone matrix and improving BMD?

Do everything you can to improve and preserve your Bone Health.

Forteo Treats Atypical Fractures of the Femur

Patients, Primary Care Docs, and Orthopedic Surgeons all worry about bone surgery while on Osteoporosis Medications.  They also worry about Atypical Fractures of the Femur (AFF).  There is one medication that actually helps bone healing and is routinely used to treat AFF.  That is the Anabolic, Forteo.

Atypical Fracture of the Femur is quite rare.  AFF has become less rare since we started treating osteoporosis with Antiresorptive Osteoporosis Medications.  Typical Femur Fractures are still about 100 times as common – and we can prevent over half of those with Antiresorptive Osteoporosis Medications.

AFF is a Stress Fracture, usually just below the hip, that starts on the lateral side of the Femur.  It is a small crack, which can gradually spread across the bone.

The best treatment for a stress fracture is stimulating the cells that make new bone (OsteoBlasts) and also stimulating the cells that gobble up bone (OsteoClasts).  This increases bone turnover, which is needed for healing a fracture, especially a stress fracture.

Forteo is the only Anabolic we currently have in the USA.  Forteo is routinely used to treat AFF before, as well as after, the fracture.  It is also used to treat other stress fractures  such as metatarsals in the feet and “shin splints” in the proximal shaft of tibia.

Forteo is also commonly used to enhance healing in osteoporotic patients in spine fusions and in total joint replacement.

If you need increased bone turnover, increased bone matrix formation, or enhanced healing of osteoporotic bone, consider the Anabolic, Forteo.

Prevent and Treat ONJ with Forteo

Dentists and Oral Surgeons are sometimes wary of their patients being on ANY Osteoporosis Medications when they undergo tooth extractions or other dental proceedures.  One osteoporosis medication is different from all the others.  Forteo is the only Anabolic medication currently available in the USA.  Forteo does not cause dental and jaw problems.  Forteo can be used to treat ONJ and other bone problems of the jaw.

OsteoNecrosis of the Jaw (ONJ) is a rare complication of tooth extraction.  If you have cancer, are on chemotherapy, have uncontrolled diabetes, or are on the higher doses of Antiresorptive Osteoporosis Medications used in Cancer Patients with Metastases, ONJ is less rare.

ONJ is the result of too slow bone repair by the OsteoBlasts (the cells that make new bone matrix).  Antiresorptive medications slow down both OsteoClasts (the cells that resorb bone) and OsteoBlasts.

Forteo cannot cause ONJ.  Forteo (Teriparatide) stimulates OsteoBlasts.  That increases new bone matrix formation.  Therefore, Forteo can prevent and treat ONJ.

Forteo has been shown to improve bone healing in dental surgery, including implant osseointegration and healing alveolar defects.  Ref:  Batshutski JD, Eber RM, Kinney JS, et al.  Teriparatide and osseous regeneration in the oral cavity.  N Engl J Med. 2010, 363:2396-2405.  Ref:  Kuchler U, Luvizuto ER, Tangl S, et al.  Short-term Teriparatide delivery and osseointegration: a clinical feasibility study.  J Dent R. 2011:90(8):1001-1006.

As a former orthopedic surgeon, I have discussed these issues with several of our local oral surgeons and dentists.

If you are facing oral surgery or tooth extraction, discuss your osteoporosis medications with your dental surgeon.  Most osteoporosis medications should be held for your surgery.  Forteo is the exception.  Forteo actually helps your jaw heal after dental surgery.

Several patients have concerns about oral surgery while taking Prolia.  This is not a problem – if you follow guidelines.

Prolia is different from other Antiresorptives.  Prolia does not accumulate in bone.  5 to 6 months after your last dose, Prolia has lost its effect of slowing bone turnover.  Therefore, it is safe to proceed with surgery on bone (including dental surgery) 6 months after your last dose.

Patients worry about OsteoNecrosis of the Jaw (ONJ), but this is very rare.  In fact ONJ virtually never occurs without a tooth extraction or serious periodontal disease.  Even then, it is rare unless you also have cancer,  have poorly controlled diabetes, or are seriously Deficient in Vitamin D3, or Calcium, or Protein intake.

Elective Orthopedic Surgery timing is the same.  If you need a Total Hip Replacement (THR) or Total Knee Replacement (TKR), schedule the surgery for 6 months after your last dose of Prolia.

Any time you plan to have surgery on bone, you should Optimize Your Bone Health First.  Get a Complete Bone Health Evaluation.  Optimize your Vitamin D level (at 40 to 80 ng/ml).  Optimize your Calcium intake in foods and supplements combined (at 400 to 500 mg at all 3 meals daily).  Optimize your daily Protein intake (1 g Protein for every kg body weight).

Sometimes you will also need the Anabolic, Forteo, to increase bone matrix and improve healing.  More about that another time.

Get the best possible result from orthopedic or dental surgery.  Wait 6 months after Prolia, and do your part to optimize your bone health.
