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

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

Alarming facts
Awareness and knowledge about osteoporosis is low among fracture patients
Despite availability of therapies proven to reduce fracture risk, even in patients who have already suffered a fracture, diagnosis and treatment of osteoporosis among fragility fracture patients remains low

45
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%)

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
