Adult women or men, age = 55 to = 90 years at randomization
Fresh unilateral low energy intertrochanteric fracture of the proximal femur as the primary injury, confirmed by X-ray
Fractures eligible for this study must have one of the following characteristics
• At least three fragments, each with displacement = 1 cm
• Extension into the subtrochanteric region
Internal fixation of the fracture with a sliding hip screw or IM nail (devices
approved by local regulatory agency), performed no later than 5 days after injury
Pre- and postoperative care performed as defined in Appendix J of the protocol
Subject or subject’s legally acceptable representative has provided informed
consent
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years)
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years)
F.1.3.1 Number of subjects for this age range
Conditions that may affect the ability to perform functional or clinical
assessments required by the protocol, such as:
• Severe symptomatic osteoarthritis of the lower extremity
• Inability to independently rise from armchair or walk 200 meters before hip
fracture (use of unilateral assistive device or rolling walker is acceptable)
• Cognitive deficit, as defined by Mini-Mental Status Examination score < 22 at
time of randomization
• Symptomatic neurological conditions such as Parkinson’s disease or persistent
gross motor or sensory deficits such as hemiparesis or hemiplegia
• Presence of concomitant injuries such as rib fractures, wrist fractures, or acute
symptomatic vertebral fractures which severely impair the ability to rise from a
chair
• Associated extremity injuries including ipsilateral or contralateral fractures of the
foot, tibia or fibula, wrist, humerus, femoral shaft, femoral head or hip dislocation,
that may delay weight-bearing beyond one week after surgery
Use of bone grafts or bone substitutes at the time of fracture fixation
Head-injury, as defined by Glasgow Coma Scale <13 prior to randomization
Major polytrauma or significant axial trauma, with Injury Severity Score > 16
Pathological fracture or history of metabolic or bone disease that may interfere
with the interpretation of the results, such as Paget’s disease, rheumatoid
arthritis, osteomalacia, osteopetrosis, ankylosing spondylitis, Cushing’s disease,
hyperprolactinemia
History of symptomatic spinal stenosis
History of facial nerve paralysis
Malignancy (except fully resected cutaneous basal cell or squamous cell
carcinoma, cervical carcinoma in situ) within the last 5 years
Severe asthma or chronic obstructive pulmonary disease or recent exacerbation
Myocardial infarction or unstable angina pectoris within the last 12 months
Current alcohol dependence
History of solid organ or bone marrow transplants
Evidence of the following per subject report, chart review or local laboratory
result (currently or within the past 5 years)
• Elevated transaminases (a) Serum aspartate aminotransferase = 2.0 x
upper limits of normal; (b) Serum alanine aminotransferase = 2.0 x upper
limits of normal
• Significantly impaired renal function as determined by a derived creatinine
clearance of = 30 mL/min using the Modification of Diet in Renal Disease
equation (Levey et al, 1999). The estimated glomerular filtration rate is
calculated as follows: estimated glomerular filtration rate (mL/min/1.73m2)
= 186 x [Serum creatinine (mg/dL)]-1.154 x [Age]-0.203 x [0.742 if subject is
female] x [1.210 if subject is black].
• Current hypocalcemia or hypercalcemia (= 1.1 x upper limit of the normal
range set by the local laboratory, after adequate volume resuscitation, is
acceptable for high calcium value)
Known to have tested positive for human immunodeficiency virus, hepatitis C
virus, or hepatitis B surface antigen
Use of the following agents affecting bone metabolism
• Denosumab within the past 6 months
• Fluoride (for osteoporosis) or IV bisphosphonates within the past 12 months
• Parathyroid hormone or strontium within the past 12 months
• Calcitonin within the past three months
• Systemic glucocorticosteroids (= 5 mg prednisone equivalent per day for more
than 10 days) within the past three months
BMP-2 or BMP-7 at the time of definitive fracture fixation
Subjects to be enrolled in DXA sub-study may not have had previous
instrumentation with implants (ie, nails, screws,
