Treat to Target #6 – Treatment

February 27, 2018 @ 7:07 pm
posted by Dr Ginther

Our goal is NO NEW FRACTURES.  Therefore, Treat to Target means a FRAX score of <20% for “major osteoporotic” and <3% for hip fracture.  Alternately, T-score of better than -1.5 if there are any fractures.

Antiresorptives do not substantially increase bone mass or BMD.  While a 3-5% BMD improvement can be seen when a long term deficiency in calcium absorption is corrected, the function of an antiresorptive is to maintain current bone mass.

If you want to substantially increase bone mass, you must use an anabolic medication.  We now have 2.  Forteo (teriparatide) has been available for 15 years.  Tymlos (abaloparatide) was approved late last spring, but has only achieved good coverage by a majority of insurance companies in the last month.

Both can be given for up to 24 months.  Both must be followed by an antiresorptive to avoid loss of gains.  Both will show continued improvement in BMD for up to 3 years after switching to an antiresorptive because calcium takes up to 3 years to fully accumulate in new bone matrix formed by an anabolic.

Both should NOT be given to anyone with open growth plates, Paget’s, radiation to bone, cancers which have or could spread to bone, elevated bone specific alkaline phosphatase other than from fracture healing, or pregnant or nursing women.

Tymlos is approved for postmenopausal women only.  It does not stimulate bone turnover significantly and therefore shows faster BMD increase initially in the hip.  It has not been tested for use after antiresorptives.

Forteo is approved for men and women with osteoporosis which is “age-related”, or from steroid use, or from idiopathic hypogonadism.  Forteo significantly increases both osteoblast and osteoclast activity, thereby stimulating bone turnover, which is often suppressed after long-term antiresorptives.  Forteo is the default treatment for ONJ and AFF.

If you are dealing with vertebral fractures on VFA, or really low BMD on DXA, or with multiple fragility fractures, you need an ANABOLIC FIRST, to decrease fracture risk.  Then follow with antiresorptives to maintain a low enough fracture risk.

Remember, even these medications will fail without proper nutrition.

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.

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.

Recently a patient asked me to review all osteoporosis medications for her to consider and choose from.  We had already optimized her Calcium intake, 25-hydroxy Vitamin D level, Protein intake, Multiple Vitamins & Minerals, and Exercise program.  These had all helped substantially, but not enough for her peace of mind.  She feels that she needs osteoporosis medication too.  Here they are:
