Osteoporosis By Jody Vulk PA-C Northwest Iowa Bone, Joint & Sports Surgeons Osteoporosis “Porous bone“ Bones lose protein & mineral content Clinical Definitions of OP Vertebral height loss of > 25% of the vertebral body 2 compression fractures 2 or more fragility fractures FRAGILITY FRACTURES A fracture from forces that would not ordinarily cause fracture in a healthy young adult. Quantified as forces equivalent to a fall from a standing height or less. Types of Fragility Fractures Compression Fractures of the Vertebra Proximal Humerus Distal Radius Fractures Hip Fractures True or False Most Common Fragility Fractures are: #1 Spine #2 Wrist #3 Hip True Spine 27% Wrist 19% Hip 14% Bone Cells Osteoclasts ■ ■ Remove or retire old bone. Active throughout lifetime. Osteoblasts ■ ■ Create new bone Best before age 35 & before menopause Osteoclasts Osteoblasts Remove Old Bone (Classic) Create new bone (having a Blast!) In Osteoporosis More of these working… than these. Osteoclasts ■ ■ Remove or retire old bone. Active throughout lifetime. Osteoblasts ■ ■ Create new bone Best before age 35 & before menopause Dual Energy X-ray Absorptiometry BMD Levels Normal = 0 to 0.9 T-Score Osteopenia = 1 to -2.4 TScore Osteoporosis = -2.5 T-Score Who needs a BMD? A woman nearing menopause (for baseline) Men over the age of 70 Women 65 or older (& have never had one) Those with risk factors for osteoporosis How often to Test Normal BMD=15 years Osteopenia=5 years Severe Osteopenia=1 year 85 or older=3 years Bone Minerals True or False To avoid Osteoporosis-- just is drink more milk. False Calcium + Vitamin D + Magnesium+ Phosphorus + Alkaline Phosphatase = Good Quality Bones Foods for Healthy Bones 10001500mg Daily Calculate Need Calcium supplements Calcium Citrate Take food 21% with or without Calcium More frequently causes gas, bloating, constipation Calcium Carbonate Requires stomach acid, take with food 40% Calcium Fewer side effects Inexpensive Calcium Zappers Osteoporosis & Vitamin D Deficiency 1 1/3 Billion worldwide of OP patients also Vitamin D deficient Vitamin D deficiency is not age dependent. Vitamin D is created through the skin by exposure to sunlight Vitamin D and Sunlight You must live near the equator to rely on its benefits. True or False Caucasians are more prone to Vitamin D deficiencies than those with darker skin. False Darker skin does not absorb Vitamin D as well. Vitamin D Rich foods Fatty fish *Cod Liver oil(1360 IU) Swordfish(566 IU) Salmon(sockeye)(447 IU) Tuna(154 IU) Fortified foods: Milk (115 IU) Orange juice (137 IU) *avoid Cod liver oil Egg yolks (41 IU). Vitamin D Supplements Cholecalciferol (Vitamin D3) Ergocalciferol (Vitamin D2) Fungal derivative Synthesized in the skin Vegan supplement Wool oil Preferred supplement Age Dosage *400 to 800 IU daily New Guidelines Adults < 50 Adults > 50 *800 to 1,000 IU daily Normal Vitamin D level, do not exceed 4,000IU daily. *Do not commit these to long term memory, follow-up research pending. Vitamin D Deficiency Risk Factors Risk Factors of Vitamin D deficiency Northern Latitudes <15 minutes of sun African American, or dark skinned Elderly Obesity Vitamin D Vitamin D is fat soluble, stored in fat Testing is on blood Loose weight, boost Vitamin D Who is at risk? True or False Men do not need to be tested for Osteoporosis. False 2 million men have OP Men are more likely to die in the first year after hip fracture. Men who fracture are less likely to be tested. Early Signs of Osteoporosis Joan Surber Age 68 Pelvic Fracture 1/28/2012 T-Score of -2.5 in her Lumbar Spine, 1.8 in the Right hip and a -2.2 in the Left hip. Vitamin D=12ng/mL Severe Osteoporosis T-score –2.5 or less & a fragility fracture has occurred. Leg braces as a child Calcaneus Fracture at age 42 Menopause at age 34 20+ year history of GERD with medication use Risks factors & Prevention Heredity/Ethnicity Don’t have it in your genes Hormonal Changes (Estrogen & Testosterone) Hormone replacement (at the guidance of your PCP) Aging Not recommending to avoid this one. Pharmaceuticals Avoid long-term use of bone depleting medications (Cont.) Risk Factors & Prevention Low BMI History of Fracture EAT! -a diet rich in colors and eat real foods! Bubble wrap (Cont.) Risk Factors & Prevention Malabsorption Poor Diet Smoking Alcohol in excess Lack of Exercise Avoid Gastric Bypass, Celiac Sprue, Anorexia… Eat FOODs rich in Vitamins and minerals Don’t do that! Limit alcohol to no more than 2 beverages daily Weight bearing exercises such as walking, tia chi, & weight lifting/resistance exercises Types of Osteoporosis Primary Secondary Relatively unknown cause other than advancing age and postmenopausal Has a known cause or reason for having developed (i.e.=oral corticosteroid use, other medications, diseases or conditions) True or False Kyphosis of the spine is “normal for aging.” False Decreasing height and humped back are not normal. They are indications of compression fractures. NWIA Bone Approach But orthopedists fix bones, Right? We Evaluate Anyone over 50 with a fractured bone from ground height. Own The Bone Nutrition Counseling • • Calcium Vitamin D Physical Activity Counseling • • Lifestyle Counseling • • For the treatment of osteoporosis Testing • Smoking Cessation Limiting excessive alcohol intake Pharmacology • Weight-bearing and muscle-strengthening exercise Fall prevention education Dual Energy X-Ray Absorptiometry (DXA) Communication • • Physician referral letter Follow-up note and educational material to patie Step-wise Approach Initially After a Fracture Remove Bisphosphonates Fracture immobilization/ fixation Draw Labs/BMD Vitamin D Correction Heal the Fracture Step-wise Approach Through the OP Clinic Check Vitamin D Increase bone mass if warranted Fracture Risk Assessment Educate patients on calcium, Vitamin D, exercises Resume Bisphosphonates Medications National Osteoporosis Foundation Recommends treatment: T-score is less than -2.0 Or Less than -1.5 with a risk factor (after the fracture has healed ) Medication Route and Frequency Use Alendronate Oral; Daily or Weekly Prevent/Manage avoid in Hyperparathyroidism or Renal Dysfunction Calcitonin Intranasal; Daily Management Ibandronate Oral or IV; Daily/Monthly/q 3 mo. Prevent/Manage avoid in Hyperparathyroidism or Renal Dysfunction Raloxifene Oral; Daily Prevent/Manage +Breast CA prevention Risedronate Oral; Daily or Weekly Prevent/Manage avoid in Hyperparathyroidism or Renal Dysfunction Teriparatide Injection; Daily Management Denosumab SubQ; q 6 mo. Management +Breast CA prevention Zoledronic acid Injection; yearly Management Exercises True or False Swimming is a great exercise to prevent osteoporosis. False Swimming does not prevent osteoporosis. Only weight bearing exercises prevent osteoporosis. Balance Training & Good Posture Resistance Training & Stretching Weight Bearing Exercise Review Calcium + Vitamin D + Magnesium+ Phosphorus + Alkaline Phosphatase = Good Quality Bones Vitamin D3 Calcium Carbonate Game Time #1 What are the top three types of compression fractures? #1) Spine 27% #2) Wrist 19% #3)Hip 14% #2 What are the top three definitions of clinical osteoporosis? Clinical Definitions of OP #1) Vertebral height loss of > 25% of the vertebral body #2) 2 compression fractures #3) 2 or more fragility fractures #3 What are the top objective (laboratory/radiological) definitions of good bone health? (I have 6 answers) Good Bone Health BMD with T-score from 0- 0.9. Vitamin D > 30ng/mL Calcium (within local lab normal limits) Magnesium (within local lab normal limits) Alkaline Phosphatase (within local lab normal limits) Phosphorus (within local lab normal limits) #4 List the top sources of Vitamin D. (7 were listed) Vitamin D sources 1. Sunlight 2. Cod liver oil 3. Swordfish 4. Salmon 5. Tuna 6. Fortified Milk 7. Fortified Orange Juice (Eggs also pictured) #5 What are some great exercises for preventing bone loss? (I have listed 6) Exercises to prevent bone loss Walking Yoga Tai Chi Weight or Strength/Resistance training Balance training Good Posture #6 What are the top risk factors for developing OP? ( I discussed 11) OP Risk Factors 1. Hereditary/ Ethnic background 2. Hormonal changes 3. Age 4. Medications 5. Low BMI 6. Previous Fractures 7. Malabsorption 8. Poor diet 9. Smoking 10.
