Beskrivelse
Inclusion Criteria:
- postmenopausal women
- with osteoporosis who have been on bisphosphonate therapy for one year or more (all bisphosphonates will be included such as alendronate, risdedronate, ibandronate, or zoledronic acid).
- Patients will also be included if they are on glucocorticoids or other medications known to affect bone mineral metabolism as these are often found in patients with these types of fractures.
- sustain an atypical subtrochanteric or diaphyseal femoral shaft fracture as defined by the the 2010 ASBMR task force. An atypical fracture must include all of the following: (1) a location in the femur distal to lesser trochanter; (2) no trauma or minimal trauma as a fall; (3) transverse or short oblique configuration; (4) noncomminuted; and (5) complete fracture extends through both cortices and may be associated with a medial spike; incomplete fractures involve only the lateral cortex. Patients who have an incomplete fracture can be included if they fall into the 2010 ASBMR task force definition.
Exclusion Criteria:
- men
- children
- those who have had radiation therapy
- Paget's disease
- treatment with teriparatide for two year in the past
- metastatic bone disease
- active cancer
- hypercalcemia
- hyperparathyroidism
- metabolic disease other than osteoporosis

Radiologic Evidence of Bone Healing
Tidsramme: 6, 12 months of treatment
|
The radiologic indices of fracture healing included (1) cortical continuity on two of four cortices, (2) persistence of alignment, (3) decreased conspicuity of fracture line, and (4) increased callus formation.
For each of these indices, healing was graded on a scale of 1 to 4 with 1 = no change (less than 25%), 2 = minimum healing (25-50%), 3 = moderate healing (50-75%), and 4 = complete healing (greater than 75%).
A composite score was calculated by summing the subscale scores for the 4 indices.
Composite score scale ranged from 4 to 16 with higher scores indicating more complete healing.
The primary grading was performed by a radiologist with expertise in musculoskeletal radiology, then independently repeated by a second radiologist, both of whom were blinded to the study allocation.
