S72.123F Displaced fracture of lesser trochanter of unspecified femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

• Displaced fracture of lesser trochanter of unspecified femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Summary

This condition involves a displaced fracture of the lesser trochanter, a bony prominence on the femur (thigh bone), where the bone fragments are out of alignment. The fracture is classified as open (type IIIA, IIIB, or IIIC), meaning the skin is broken, and it is a subsequent encounter indicating the fracture is healing routinely. The lesser trochanter serves as an attachment point for muscles, and displacement may affect muscle function and stability.

Causes

Displaced fractures of the lesser trochanter typically result from trauma, such as falls or direct impact injuries. Open fractures occur when the fractured bone pierces the skin, often due to high-energy trauma. These injuries can also occur in individuals with weakened bones, such as those with osteoporosis, where even minor stress may cause a fracture.

Risk Factors

• Advanced age, particularly in postmenopausal women at risk of 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.
• Visible wound or open skin if the fracture is open.

Diagnosis

Diagnosis typically involves a physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays or CT scans, are used to confirm the fracture type, displacement, and whether the fracture is open. The classification of open fracture type (IIIA, IIIB, or IIIC) is determined based on the severity of soft tissue damage and contamination. Routine healing is assessed through follow-up imaging and clinical evaluation.

Treatment Options

Treatment depends on the fracture's severity and alignment. Non-surgical options may include immobilization with a cast or brace, pain management, and physical therapy. Surgical intervention may be necessary for unstable or severely displaced fractures, involving internal fixation to realign and stabilize the bone. Open fractures require wound care and antibiotics to prevent infection. Routine healing is monitored through regular follow-up appointments.

Prognosis and Follow-Up

With proper treatment, most displaced fractures of the lesser trochanter heal routinely. Recovery time varies but often ranges from several weeks to months, depending on the fracture type and treatment. Follow-up appointments are essential to monitor healing, assess functional recovery, and adjust treatment as needed. Physical therapy may be recommended to restore strength and mobility.

Complications

Potential complications include infection (especially with open fractures), nonunion or malunion of the fracture, chronic pain, and reduced mobility. Nerve or blood vessel damage may occur in severe cases. Early intervention and adherence to treatment plans can help minimize these risks.

Lifestyle & Prevention

To support healing, avoid weight-bearing on the affected leg as advised. Engage in prescribed physical therapy to maintain muscle strength and flexibility. For prevention, maintain bone health through a balanced diet rich in calcium and vitamin D, regular weight-bearing exercise, and avoid high-risk activities that increase fall or injury likelihood.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or an open wound after an injury. Contact your healthcare provider if you notice increased pain, signs of infection (e.g., redness, pus), or difficulty moving the leg during recovery.

Tips for Medical Coders

Use this code for a subsequent encounter of a displaced lesser trochanter fracture with an open type IIIA, IIIB, or IIIC classification, where routine healing is documented. Ensure the encounter is subsequent (not initial) and that the fracture type and healing status are clearly recorded in the medical documentation. Verify that the fracture is of the lesser trochanter (not the greater trochanter) and that the femur is unspecified.
