Which fixation device is indicated for a femoral neck fracture?

Cannulated screw fixation is indicated in nondisplaced, intracapsular FNFs in elderly patients, and in displaced fractures in younger patients with ideal bone quality.

How do you fix a femoral neck fracture?

The standard of care for a displaced fracture where the blood supply is disrupted involves replacing the femoral head (hemiarthroplasty or a total hip arthroplasty). If there’s no displacement, then surgically stabilizing the fracture with screws or other hardware may be done.

When do you use cannulated screws?

Fully threaded screws are intended to be used to stabilize fractures with little to no compression across the fracture. The cannulated screws and instruments also allow for minimally invasive percutaneous insertion. The Cannulated Screw System is commonly used in the hip, pelvis, knee, ankle, and foot.

What does cannulated screw mean?

Cannulated screws are a common method of fixation used by orthopedic surgeons for multiple fracture patterns. These screws may be cannulated or “hollow” to allow them to be placed over a guidewire facilitating better alignment prior to drilling or screw insertion.

How long does a femoral neck fracture take to heal?

Most femoral fractures take about 4 to 6 months to heal completely, but you should be able to resume many activities before this time.

What stability can multiple cannulated screws offer in the treatment of femoral neck fractures?

The more accurate placement of the cannulated screw, the higher the stability of internal fixation of femoral neck fractures and the lower the risk of fracture nonunion20.

How long does a femoral neck stress fracture take to heal?

Treatment of Stress Fracture Bone generally takes 6-8 weeks to heal and this is the period of time where crutches and non-weight bearing are required. This period can be followed by a period of progressive partial weight bearing (still with crutches) and hopefully crutches can be discarded at approx. 12 weeks.

What is the purpose of the hole in a cannulated screw?

The drilling allows the cannulated screws to follow the path made by a wire milling machine, also called Kirschner wire, and it is necessary for the positioning of the screw in the bone.

Can you walk with a femoral neck stress fracture?

Regardless of the grading all patients with a FNSF should cease all impact activities (running and jumping sports) for a minimum of 6 weeks. If there is any pain with walking, standing or the development of night pain, crutches will be required for a minimum of 3 weeks.

What stability can sliding hip screw offer in the treatment of femoral neck fractures?

It is less invasive, can preserve the femoral head, and the hip function is better after healing [12]. However, orthopedic surgeons are often perplexed by postoperative complications of internal fixation, such as avascular necrosis, non-union, implant failure, and reoperation [13, 14].

Is it best to precut screw for femoral neck fracture?

Do not push forcefully or you may distract the fracture. In young patients with hard bone it is best to use the tap to precut the thread for the screw. Otherwise the screw may not advance, and you may actually displace the fracture by twisting the proximal fragment as you attempt to insert the screw.

Where are the screws on the femoral neck?

Biomechanically, the most effective component of this fixation is the third, inferior obtuse screw, supported along considerable distance on both the inferior and posterior cortices of the femoral neck following its spiral anterior curve.

How does Percutaneous screw fixation of neck fractures work?

Technique of percutaneous screw fixation of neck fractures. The great advantage of this method for the patient consists of the precise percutaneous insertion of screws through a small stab incision. Furthermore, thanks to the long instruments the surgeon is not forced to put his hands into the x-ray beam.

Is there a cure for a femoral neck fracture?

Impacted and nondisplaced femoral neck fixation using multiple cancellous lag screws. Whereas virtually all fractures. replacement may be difficult. Although different investigators have solely on patient care or fracture type is preferable or even possible. treatment) to arrive at a treatment decision.
