S72.122 Displaced fracture of lesser trochanter of left femur

Name of the Condition

• Displaced fracture of lesser trochanter of left femur

Summary

This condition involves a break in the lesser trochanter of the left 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 range of motion and tenderness. Imaging like X-rays or CT scans is used to confirm the fracture's location and displacement. Additional tests may be ordered to evaluate bone density or rule out underlying conditions.

Treatment Options

• Rest and avoidance of weight-bearing activities promote healing.
• Pain management with medications or physical therapy.
• Surgical intervention may be required for severe displacement or unstable fractures.
• Rehabilitation focuses on restoring strength and mobility.

Prognosis and Follow-Up

Most fractures heal with proper treatment, but recovery time varies based on severity and patient health. Follow-up visits monitor healing progress and adjust treatment plans as needed. Long-term outcomes depend on adherence to rehabilitation and management of underlying conditions.

Complications

• Nonunion or delayed healing of the fracture.
• Avascular necrosis (loss of blood supply to the bone).
• Chronic pain or reduced mobility.
• Infection (if surgical intervention is required).

Lifestyle & Prevention

• Maintain bone health through adequate calcium and vitamin D intake.
• Engage in weight-bearing exercises to strengthen bones.
• Use protective gear during high-impact activities.
• Address fall risks by modifying the home environment for older adults.

When to Seek Professional Help

Seek immediate medical attention if you experience severe hip pain, inability to bear weight, or signs of infection (e.g., fever, increased swelling). Follow up with a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the laterality (left femur) and displacement status clearly in the medical record. Ensure the fracture is confirmed by imaging and note any associated injuries or underlying conditions that may impact coding. Use this code for acute, displaced fractures of the lesser trochanter; subsequent encounters or healing phases require different codes.
