S72.121 Displaced fracture of lesser trochanter of right femur

Name of the Condition

• Displaced fracture of lesser trochanter of right femur

Summary

This condition describes a broken segment of the lesser trochanter in the right femur where the bone fragments are out of alignment. The lesser trochanter is a bony prominence on the femur that serves as an attachment point for muscles. Displacement indicates the fracture fragments have shifted from their normal anatomical position, which may affect muscle function and stability.

Causes

Displaced fractures of the lesser trochanter typically result from trauma, such as falls or direct impact injuries. They can also occur in individuals with weakened bones due to conditions like osteoporosis, where even minor stress may cause a fracture. High-energy injuries, such as motor vehicle accidents, are common causes in younger populations.

Risk Factors

• Advanced age, particularly in postmenopausal women with osteoporosis.
• Conditions that weaken bones, such as osteoporosis, osteopenia, or metastatic bone disease.
• Participation in high-impact or contact sports.
• History of previous fractures or falls.
• Sedentary lifestyle or reduced bone density due to inactivity.

Symptoms

• Pain in the hip or groin area, often worsened by movement.
• Swelling and bruising around the hip.
• Difficulty bearing weight on the affected leg.
• Muscle weakness or limited range of motion in the hip.

Diagnosis

Physical examination includes assessing pain, tenderness, and range of motion. Imaging studies, such as X-rays or CT scans, are used to confirm the fracture and evaluate the degree of displacement. Additional tests may be ordered to rule out associated injuries or underlying bone conditions.

Treatment Options

• Non-surgical management with rest and activity modification to allow healing.
• Surgical intervention, such as internal fixation with screws or plates, may be required for significant displacement or unstable fractures.
• Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Most displaced fractures of the lesser trochanter heal with appropriate treatment, though recovery time varies. Follow-up imaging may be recommended to monitor healing progress. Long-term outcomes depend on the severity of the fracture, treatment approach, and any underlying bone health issues.

Complications

• Nonunion or delayed healing of the fracture.
• Muscle weakness or functional impairment.
• Chronic pain or arthritis in the hip joint.
• Risk of future fractures due to underlying bone fragility.

Lifestyle & Prevention

• Maintain bone health through a diet rich in calcium and vitamin D.
• Engage in weight-bearing exercises to strengthen bones.
• Use fall prevention strategies, such as removing tripping hazards at home.
• Avoid high-impact activities if at risk for bone fractures.

When to Seek Professional Help

Seek immediate medical attention if you experience severe hip pain, inability to bear weight, or visible deformity after an injury. Persistent pain, swelling, or difficulty walking after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the laterality (right femur) and displacement status clearly. Ensure the fracture is specified as involving the lesser trochanter and not other trochanteric regions. Include details about the fracture's cause (trauma vs. underlying condition) if available, as this may impact coding accuracy.
