S72.123 Displaced fracture of lesser trochanter of unspecified femur

Name of the Condition

• Displaced fracture of lesser trochanter of unspecified femur

Summary

This condition involves a break in the lesser trochanter, a bony prominence on the femur (thigh bone), where the bone fragments are out of alignment. The lesser trochanter serves as an attachment point for muscles and ligaments, and 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, displacement, and severity.

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

Prognosis depends on fracture severity, treatment, and underlying bone health. Most fractures heal with proper care, but follow-up imaging and physical therapy are often needed to monitor progress and prevent complications.

Complications

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

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 and using assistive devices if needed.

When to Seek Professional Help

Seek immediate medical attention for severe hip pain, inability to bear weight, or visible deformity. Follow up with a healthcare provider if pain persists or worsens after initial treatment.

Tips for Medical Coders

Document the fracture's displacement and specify the femur as "unspecified" when laterality is not documented. Ensure clinical notes support the diagnosis and treatment provided.
