Intertrochanteric hip fractures are a type of extracapsular hip fracture that occurs in the proximal femur, specifically between the greater and lesser trochanters. This region is a critical area of the hip, and fractures here can be challenging to manage. As an orthopedic expert with over a decade of experience in treating hip fractures, I have seen firsthand the impact that these injuries can have on patients' quality of life. Understanding the causes, symptoms, and treatment options for intertrochanteric hip fractures is essential for providing optimal care and improving patient outcomes.
The incidence of intertrochanteric hip fractures is significant, with over 150,000 cases reported annually in the United States alone. These fractures typically occur in older adults, with a higher prevalence in women due to the increased risk of osteoporosis. The average age of patients with intertrochanteric hip fractures is around 80 years old, and the mortality rate within one year of the fracture is approximately 20-30%. These statistics highlight the importance of prompt and effective treatment.
Causes of Intertrochanteric Hip Fractures
Intertrochanteric hip fractures often result from a combination of factors, including osteoporosis, trauma, and age-related decline in bone density. The most common causes of intertrochanteric hip fractures include:
- Falls from a standing height or greater
- Direct trauma to the hip, such as from a motor vehicle accident
- Osteoporosis, which weakens the bone and increases the risk of fracture
- Age-related decline in bone density
In addition to these causes, other factors can contribute to the risk of intertrochanteric hip fractures, such as a history of previous fractures, smoking, and certain medical conditions like diabetes and rheumatoid arthritis.
Symptoms of Intertrochanteric Hip Fractures
The symptoms of intertrochanteric hip fractures can vary depending on the severity of the injury. Common symptoms include:
- Severe pain in the hip, groin, or thigh
- Swelling and bruising around the hip
- Deformity or shortening of the affected leg
- Limited mobility or inability to bear weight on the affected leg
In some cases, patients may experience referred pain in the knee or lower back, which can make diagnosis more challenging. A thorough physical examination and imaging studies, such as X-rays or CT scans, are essential for confirming the diagnosis.

Treatment Options for Intertrochanteric Hip Fractures
The primary goal of treatment for intertrochanteric hip fractures is to restore function, alleviate pain, and prevent complications. Treatment options vary depending on the severity of the fracture, patient age, and comorbidities.
Non-Surgical Treatment
Non-surgical treatment is typically reserved for patients with nondisplaced or minimally displaced fractures. This approach may involve:
- Pain management with medication
- Bed rest or limited weight-bearing activities
- Physical therapy to maintain range of motion and strength
However, non-surgical treatment is often associated with a higher risk of complications, such as pressure sores, deep vein thrombosis, and pneumonia.
Surgical Treatment
Surgical treatment is often necessary for patients with displaced fractures or those who are unable to tolerate non-surgical management. The most common surgical options include:
- Intramedullary nailing: a minimally invasive procedure that involves inserting a metal rod into the marrow cavity of the femur to stabilize the fracture.
- Sliding hip screw fixation: a procedure that involves inserting a screw into the femoral head and a plate into the femur to stabilize the fracture.
- Plate fixation: a procedure that involves attaching a metal plate to the femur to stabilize the fracture.
The choice of surgical technique depends on the fracture pattern, patient age, and surgeon preference.
| Surgical Technique | Success Rate |
|---|---|
| Intramedullary nailing | 85-90% |
| Sliding hip screw fixation | 80-85% |
| Plate fixation | 75-80% |
Complications and Prognosis
Intertrochanteric hip fractures are associated with a significant risk of complications, including:
- Malunion or nonunion: failure of the fracture to heal properly
- Infection: bacterial infection of the fracture site
- Hardware failure: failure of the surgical implant
- Chronic pain: persistent pain after fracture healing
The prognosis for patients with intertrochanteric hip fractures varies depending on the severity of the fracture, patient age, and comorbidities. In general, patients with nondisplaced fractures have a better prognosis than those with displaced fractures.
