Hip Fracture Treatment

Orthopedic Surgery

How is a hip fracture treated?

Once the hip fracture has been diagnosed, the patient's overall health and medical condition will be evaluated. In very rare cases, the patient may be so ill that surgery would not be recommended. In these cases, the patient's overall comfort and level of pain must be weighed against the risks of anesthesia and surgery.

Most surgeons agree that patients do better if they are operated on fairly quickly. It is, however, important to insure patients' safety and maximize their overall medical health before surgery. This may mean taking time to do cardiac and other diagnostic studies before surgery.

How is a hip fracture treated without surgery?

Patients who cannot have surgery include those who are too ill to undergo any form of anesthesia and people who were unable to walk before their injury and may have been confined to a bed or a wheelchair.

Certain types of fractures may be considered stable enough to be managed without surgery. Because there is some risk that these "stable" fractures may instead prove unstable and displace (change position), the doctor will need to follow with periodic x-rays of the area. If patients are confined to bed rest as part of the management for these fractures, they will need to be closely monitored for complications that can occur from prolonged immobilization. These include infections, bed sores, pneumonia, the formation of blood clots, and nutritional wasting.

How is a hip fracture treated with surgery?

Intracapsular Fracture

Intracapsular Fracture Repair

Repair of an intracapsular fracture with individual screws.

Intracapsular fracture Repair

Repair of an intracapsular fracture with a single compression hip screw.

If the head of the femur ("ball") alone is broken, management will be aimed at fixing the cartilage on the ball that has been injured or displaced. Frequently with these injuries, the socket, or acetabulum, may also be broken. The surgeon will need to take this into consideration as well.

These injuries may be approached either from either the front or back of the hip. In some cases, both approaches are required in order to clearly see and fix the injured bone. For true intracapsular hip fractures, the surgeon may decide either to fix the fracture with individual screws (percutaneous pinning) or a single larger screw that slides within the barrel of a plate. This compression hip screw will allow the fracture to become more stable by having the broken area impact on itself. Occasionally, a secondary screw may be added for stability.

If the intracapsular hip fracture is displaced in a younger patient, a surgical attempt will be made to reduce, or realign, the fracture through a larger incision. The fracture will be held together with either individual screws or with the larger compression hip screw.

In these cases, the blood supply to the ball, or head of the femur, may have been damaged at the time of injury (avascular necrosis). Even though the fracture is realigned and fixed into place, the cartilage and underlying supporting bone may not receive adequate blood. Over a period of time, this may cause the femoral head to flatten out. When this occurs, the joint surface becomes irregular. Ultimately, the hip joint may develop a painful arthritis, despite the surgical repair.

In the older patient, the chance that the head of the femur is damaged in this way is higher. It is generally felt that for these displaced fractures, patients will do better if some of the components of the hip are replaced. In some cases, this can mean a replacement of the ball, or head of the femur (hemiarthroplasty). In other cases, this can mean the replacement of both the ball and socket, or head of the femur and acetabulum (total hip replacement).

Intertrochanteric Fracture

Intertrochanteric Fracture Repair

Repair of an intertrochanteric fracture with an intramedullary nail. The nail is in the hollow cavity of the femur (thighbone) rather than on the side of it (as with a plate).

Most intertrochanteric fractures are managed with either a compression hip screw or an intramedullary nail.

The compression hip screw is fixed to the outer side of the bone with bone screws and hasa large secondary screw (lag screw) that is placed through the plate into the neck and head of the hip (see compression hip screw figure above). The design of the device helps increase the stability of the area and promote healing.

The intramedullary nail is placed directly into the marrow canal of the bone through an opening made at the top of the greater trochanter. A lag screw is then placed through the nail and up into the neck and head of the hip. There are no definitive studies to show that one device is superior to another. The decision as to which to use is based on the surgeon's preference and experience

Subtrochanteric Fracture

Subtrochanteric Fracture Repair

Repair of subtrochanteric fracture with a long intramedullary nail.

Subtrochanteric Fracture Repair

Interlocking screws at the end of the nail make it more secure.

At the subtrochanteric level, most fractures are managed with a long intramedullary nail together with a large lag screw or they are managed with screws that capture the neck and head of the femur or the area immediately underneath it, if it has remained intact.

In order to keep the bones from rotating around the nail or from shortening ("telescoping") on the nail, additional screws may be placed at the lower end of the nail in the area of the knee. These are called interlocking screws.

In certain cases, the surgeon may choose to use a plate rather than a nail. The plate will have screws that go into the bone from the lateral, or outer, side of the femur. A single large screw goes into the neck and the head of the femur and appears similar to the compression hip screw, but at a different angle. Secondary screws are then placed through the plate into the bone to hold the fracture in place

  • A locking plate may be used for more difficult to treat fractures.

What is recovery from a fractured hip like?

Pain Management

Pain after an injury or surgery is a natural part of the healing process. Your doctor and nurses will work to reduce your pain, which can help you recover faster. Medications are often prescribed for short-term pain relief after surgery or an injury.

Be aware that although opioids help relieve pain after surgery or an injury, they are a narcotic and can be addictive. Opioid dependency and overdose has become a critical public health issue in the U.S. It is important to use opioids only as directed by your doctor. As soon as your pain begins to improve, stop taking opioids. Talk to your doctor if your pain has not begun to improve within a few days of your treatment.

Rehabilitation

Patients may be encouraged to get out of bed the day after surgery with the assistance of a physical therapist. The amount of weight that is allowed to be placed on the injured leg will be determined by the surgeon and is generally a function of the type of fracture and treatment to fix it. The physical therapist will work with the patient to help regain strength and the ability to walk. This process may take up to three months.

Medical Care

Occasionally, a blood transfusion may be required after surgery, but longer term antibiotics are generally not necessary. Most patients will be placed on medicine to thin their blood to reduce the chances of developing blood clots for up to 6 weeks. These medicines may be in the form of pills or injections. Elastic compression stockings or inflatable compression boots may also be used.

Follow-Up Care

During the appointments that take place after surgery, the surgeon will want to check the wound, remove sutures, follow the healing process using X-rays, and prescribe additional physical therapy, if necessary. Following hip fracture surgery, most patients will regain much, if not all, of the mobility and independence they had before the injury.
