general information

The GANNET is a new medical implant, specifically designed for the surgical fixation of fractured hips with the fracture just below the femoral head. The standard treatment currently consists of fixation of the bone fracture by means of a screw that is fixed by a plate and screws. Unfortunately, this treatment appears to fail once in three times. One of the main reasons for this is that with the conventional surgical techniques it is insufficiently mounted.

The Gannet was developed in the Netherlands, with the aim to obtain a better fixation of the fractured hip. Loading tests have shown that the Gannet gives a more stable fixation of the fractured hip as compared to the current implants. The data obtained with the clinical trials based on applying the Gannet demonstrate that a high percentage of fractures heal without complications.

The aim is to perform the operation within twenty-four hours after admission. The operation is preferably carried out with epidural anaesthesia, or general anaesthesia. After this, the fracture is put under X-ray screening. The surgical approach is carried out by a cut on the outside under the hip. Under X-ray screening and with help of an aiming device, a guide wire in the center of the femoral head is inserted. The guide wire is used to drill a channel. Afterwards, the Gannet is inserted in the hip and mounted on a side plate. The side plate is fixed with two bone screws to the femur.

After this procedure the Gannet with the built-in anchors are fixed in the femoral head. The wound will be closed. After surgery the leg cannot be fully charged for 6 weeks, meaning that the patient has to walk with the aid of a walker, or crutches. Outpatient monitoring includes X-ray after 6 weeks and after 3, 6 and 12 months.
