Transcript of 5 Osteoporosis Fractures Lecture Summary

  • 1Osteoporosis and fracturesAn orthopaedic perspective

    Why is the Orthopaedic Surgeons Initiative needed?

    Fragility fractures are a large and growing health issue 1 in 2 women and 1 in 4 men over 50 yrs of age will suffer a fracture in

    their remaining lifetime

    A prior fracture increases the risk of a new fracture 2- to 5-fold

    Yet few fracture patients receive evaluation and treatment of osteoporosis, the underlying cause of most fragility fractures Calls for action to improve the evaluation and treatment of fracture

    patients have been published around the World1,2

  • 31. Eastell et al. QJM 2001; 94:575-592. Bouxsein et al. J Am Acad Ortho Surg. 2004; 12:385-95

    Orthopaedic surgeons have a unique opportunity

    Fragility fracture is often the first indication a patient has osteoporosis

    Orthopaedic surgeons are often the first and may be the only physician seen by fracture patients

    The orthopaedist can serve a pivotal role in optimizing treatment, not only of the fracture, but also of the underlying disease

  • 4Multinational Survey of Osteoporotic Fracture Management

    Survey of 3422 orthopaedic surgeons from 6 countries

    90% do not routinely measure bone density following the first fracture

    75% are lacking appropriate knowledge about osteoporosis

    Dreinhfer et al. Osteoporos Int 2005; 16:S44-S54

  • 5Goals of the Orthopaedic Surgeons Initiative Improve awareness of the scope and magnitude of fragility

    fractures as a global public health concern

    Improve understanding of osteoporosis and recognition that it is the underlying cause of most fragility fractures

    Motivate orthopaedic surgeons to take an active role in optimizing care of the fragility fracture patient with the ultimate goal of preventing future fractures

    Fragility fractures and osteoporosis: an expanding epidemic with devastating consequences

    Osteoporosis and fragility fractures: definition and etiology

  • 7Outline

    Fragility fractures and osteoporosis: an expanding epidemic with devastating consequences

  • 8Osteoporosis and fragility fractures:

    An expanding epidemic

  • 9Fragility fractures are common

    1 in 2 women and 1 in 5 men over age 50 will suffer a fracture in their remaining life time1

    55% of persons over age 50 are at increased risk of fracture due to low bone mass

    At age 50, a womans lifetime risk of fracture exceeds combined risk of breast, ovarian & uterine cancer

    At age 50, a mans lifetime risk of fracture exceeds risk of prostate cancer

    Fractures will be more common

    Fracture incidence projected to increase 2- to 4-fold in the next decades due to ageing of the population

    In Europe 12% to 17% of population >65 in 2002

    20% to 25% of population >65 in 2025

  • 21Economic cost of osteoporosis and fragility fractures in Europe

    In Europe the total direct costs of osteoporotic fractures are over 31 billion and are expected to increase to more that 76 billion in 20501

    In France osteoporotic hip fractures are estimated to cost about 1 billion every year2

    In Spain the total direct hospital cost of osteoporotic fractures in 1995 was ~ 222 million2

    In England & Wales the total direct hospital cost of osteoporotic fractures in 1999 was ~ 847 million2

    Fragility fractures are common and have severe consequences

    Fragility fractures lead to major morbidity, decreased quality of life and increased mortality

    10-25% excess mortality

    50% unable to walk independently after hip fracture

    50% show substantial decline from prior level of function (many lose ability to live independently)

    Increased depression, chronic pain, disability

    Increased risk of subsequent fracture

    Alarming facts

    Treatment of osteoporosis:Are physicians missing an opportunity?

    Among 1162 women with distal radius fracture, at 6 mo 266 (23%) prescribed osteoporosis med 33 (2.8%) had bone density test 20 (1.7%) had bone density + OP therapy

    883 (76%) received neither bone density test nor medical treatment of osteoporosis

    Among 1654 patients (age > 50 yrs) admitted to hospital for a fracture resulting from a fall: ~ 50% hip fracture, at 1 yr 247 (15%) prescribed osteoporosis med Women: 3 times more likely to receive treatment than men (19% vs 5%)

    Optimal care of the fragility fracture patient Diagnosis of fragility fracture

    Identify fragility fracture & underlying disease, incorporate into existing workup

    Influences treatment plan from the onset

    General fracture management Stabilize patient, pain relief, fracture care

    Rehabilitation Minimize dependence, maximize mobility

    Rehabilitation in the fragility fracture patient

    Goal is to improve strength, balance, position sense, reactions to: Improve level of function /

    independence

    Decrease risk of falls

    Decrease risk of fractures

    Balance (position sense, reaction)

    Mechanical vibration plate

    Limb and core strength

    Mobility in activities of daily living

    Safety in gait and transfers

    Sensory and visual limitations

    Home safety evaluation and adaptation

    Optimal care of the fragility fracture patient

    Diagnosis of fragility fracture Identify fragility fracture & underlying disease, incorporate into

    existing workup

    Influences treatment plan from the onset

    General fracture management Stabilize patient, pain relief, fracture care

    Rehabilitation Minimize dependence, maximize mobility

    Secondary prevention Treat and monitor underlying disease, prevent future fractures

    Ideally begins during acute and sub-acute fracture care

  • 70

    Secondary prevention basics Further evaluation of underlying disease

    Bone mineral density

    Rule out secondary causes of osteoporosis

    Initiate osteoporosis therapy, as indicated

    Fall prevention

    Inform patient and primary MD doctor of probable fragility fracture and osteoporosis

    Ensure patient has follow-up care with PT and physician treating osteoporosis (if not orthopaedist)

  • 71

    Interventions to reduce future fracture risk

    Basics Nutrition, exercise, fall prevention strategies

    Modify risk factors as able (smoking, excess alcohol)

    Treat co-morbidities (i.e., endocrine disorder?)

    Pharmacological agents

  • 72

    Interventions: General recommendations

    Regular physical activity Maintaining safe ambulatory status, indep ADLs

    Daily limb and core home exercise routine

    Sufficient intake of calcium and vitamin D daily 1000-1500 mg calcium, 400-800 IU vitamin D

    by foods or foods and supplements combined

    Adequate nutrition

    Avoid cigarettes, excess alcohol

    Pharmacological agents for treatment of osteoporosis

    Effective therapies are widely available andcan reduce vertebral, hip and other fractures

    by 30% to 65%,

    even in patients who have already suffered a fracture

  • 74

    Bisphosphonates Alendronate (FOSAMAX) Risedronate (ACTONEL) Ibandronate (BONVIVA) Zolendronate (ACLASTA)

    Pharmacological agents shown to reduce fracture risk

    SERMs Raloxifene (EVISTA)

    Stimulators of bone formation rh-PTH (FORTEO)

    Mixed mode of action Strontium ranelate (PROTELOS)

    Hormone therapy Estrogen / progestin

    Orthopaedists role in improving fragility fracture care

    Opportunity or obligation?Either way, it is:

    important not Difficult rewarding becoming standard of care

  • 77

    The orthopaedists responsibilities in fragility fracture care

    Identify the orthopaedic patient with a possible fragility fracture

    Inform the patient about the need for an osteoporosis evaluation

    Investigate whether osteoporosis is an underlying cause of the fracture

    Ensure that appropriate intervention is initiated

    Educate the patient and the family

    Coordinate care with other treating physicians

    Bouxsein et al. J Am Acad Orthop Surg, 2004; 12:385-95

  • 78

    Summary and conclusions Fractures are common. Fractures will be more common

    Osteoporotic fractures are associated with increased morbidity & mortality

    A fracture is among the strongest risk factors for future fracture. Refracture rate is high

    Majority of patients with fragility fractures are not evaluated or treated for osteoporosis

    Effective treatments are available

    Orthopaedic surgeons are usually the treating physician and can take an active role in optimizing care of the fragility fracture patient
