To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Surgery - Gamma3 Intramedullary Nails (Stryker)
Treatment: Surgery - Sliding Hip Screws

Active comparator: 1 - Gamma3 Intramedullary Nails

Active comparator: 2 - Sliding Hip Screws


Treatment: Surgery: Gamma3 Intramedullary Nails (Stryker)
The Gamma3 nail is cannulated for Guide-Wire-controlled insertion, and features a conical tip for optimal alignment with the inner part of the cortical bone. A single distal Locking Screw is provided to stabilize the nail in the medullary canal and to help to prevent rotation in complex fractures.

Treatment: Surgery: Sliding Hip Screws
The sliding hip screw is a single larger diameter partially threaded screw, which is affixed to the proximal femur with a side plate (with a minimum of two holes and a maximum of four holes) and no supplemental fixation.

Eligibility
Key inclusion criteria
1. Adult men or women aged 18 years and older (with no upper age limit).
2. An intertrochanteric fracture (stable or unstable), AO Type 31-A1 or 31-A2, confirmed with anteroposterior and lateral hip radiographs, computed tomography, or magnetic resonance imaging (MRI).
3. Low energy fracture (defined as a fall from standing height).
4. No other major trauma.
5. Patient was ambulatory prior to fracture, though they may have used an aid such as a cane or a walker.
6. Anticipated medical optimization of the patient for operative fixation of the proximal femur.
7. Operative treatment within 7 days after the trauma.(Operative treatment should take place as soon as possible as permitted by each institution's standard of care.)
8. Provision of informed consent by patient or proxy.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Associated major injuries of the lower extremity (i.e., ipsilateral and/or contralateral fractures of the foot, ankle, tibia, fibula, or knee; dislocations of the ankle, knee, or hip).
2. Retained hardware around the affected proximal femur.
3. Infection around the proximal femur (i.e., soft tissue or bone).
4. Patients with disorders of bone metabolism other than osteoporosis (i.e., Paget's disease, renal osteodystrophy, or osteomalacia).
5. Patients with Parkinson's disease severe enough to increase the likelihood of falling or severe enough to compromise rehabilitation.
6. Patients with a subtrochanteric fracture.
7. Patients with a pathologic fracture.
8. Patients with a reverse oblique fracture pattern, fracture AO Type 31-A3.
9. Obesity in the judgment of the attending surgeon.
10. Off-label use of the implant.
11. Patients with a previous history of frank dementia that would interfere with assessment of the primary outcome (i.e., EQ-5D at 1 year).
12. Likely problems, in the judgment of the Site Investigators, with maintaining follow-up. We will, for example, exclude patients with no fixed address, those who report a plan to move out of town in the next year, or intellectually challenged patients without adequate family support.
13. Patient is enrolled in another ongoing drug or surgical intervention trial.
14. If the attending surgeon believes that there is another reason to exclude this patient from INSITE. This reason will be documented on the case report forms (CRFs).
