25 million Americans have osteoporosis ½ of all post-menopausal women will have an OP related fracture Up to 20% of hip fracture patients die in one year Usually asymptomatic until fracture occurs Burden

Trabecular bone Also called Cancellous bone Vertebral body bone Bone near joint lines Has bone marrow Light weight Has spiculated pattern BONE

Cortical bone Compact bone Long bones Dense Stiff hard heavy BONE

Trabecular bone, 25% replaced per year Cortical bone, 3% replaced per year Osteoporosis occurs in both It makes sense that trabecullar bone fractures easier? BONE

Age Gender Prior fracture Family history Exercise Smoking RA ETOH Drugs….steroids RISK FACTORS

Obesity? Athletic childhood? Osteoarthritis? Diet?? Family history? NON-RISK FACTORS??

All women at age 65 Women under 65 with FRAX score >9.3% 9.3% is risk of asymptomatic woman age 65 A previous fracture? We are not screening now! SCREENING( i.e. asymptomatic)

DEXA is best Heel quantitative ultrasound?? How to Screen

Dual energy x-ray absortiometry One x-ray beam is absorbed by soft tissue One x-ray is absorbed by everything Subtract the two and get bone Problem with ordering a screening BMD on PP??? – Diagnosis: “Pre Menopausal” DEXA

-1.0 or better is normal Lower than -2.5 is osteoporosis -1.0 to -2.4 is osteopenia What if I have had a compression fracture? What if I had a hip replaced? T-SCORE

FRAX

Calcium Vitamin D Should I measure What does it mean Will replacement help Exercise?? Treatment

alendronate (Fosamax ® ) 70 mg qweek Ibandronate (Boniva ® ) 150 mg qmonth risedronate (Actonel ® ) 5 qday,35 qweek, 150 qmonth Zoledronic acid (Reclast ® ) qyear IV Bisphosphonates

Teriparitide sq qday times 2 years Risk…osteosarcoma Used to treat osteoporosis with prior fracture or high risk who cannot take bisphosphonates Forteo ®

5 years? 7 years? Life? Until BMD better? Bisphosphonates accumulate in bone and after stopping leach out over 1-2 years How long to Treat?

Mild risk: rx 5 years and follow BMD High risk: rx 10 years and do 1-2 year drug holiday Expert Opinion

Normal with no risks: 3-5 year Risk factors that persist: 2 years High risk after menopause: 2 years Treated patients: 2 years than less if responding When to rescan

Osteonecrosis of jaw=>60,000 and most occurred in cancer patients treated with very high dose zoledronic acid Atypical femur fracture=? 25,000? Risks NNH

Benefits NNT Prior FractureNo Prior Fracture Any Fracture = 21 Vertebral Fracture = 8 Hip Fracture = Other Fracture = – 66

Osteoporosis Detailing Sheet

If patient is age 65 or over and female, has the patient ever had a DXA scan? If patient is 65 or over and female, has the patient’s risk of fracture (FRAX) been calculated? Does the patient report ever having a fractured bone? Practice Partner Template Progress Notes
