S72.125F Nondisplaced fracture of lesser trochanter of left femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

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

Summary

This condition involves a break in the lesser trochanter of the left femur where the bone fragments remain in their normal anatomical position. The lesser trochanter is a bony prominence on the femur that serves as an attachment point for muscles. The fracture is classified as open (type IIIA, IIIB, or IIIC), meaning there is a wound communicating with the fracture site, and this is a subsequent encounter for treatment with routine healing.

Causes

Nondisplaced 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 side.
• Possible visible wound or open area if the fracture is open.

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. The classification of the open fracture (IIIA, IIIB, or IIIC) is determined by the severity of soft tissue damage and contamination.

Treatment Options

• Immobilization with a cast or brace to allow healing.
• Pain management with medications.
• Surgical intervention may be required for severe open fractures to clean the wound and stabilize the bone.
• Physical therapy to restore strength and mobility once healing progresses.

Prognosis and Follow-Up

With routine healing, most nondisplaced fractures of the lesser trochanter heal well with appropriate treatment. Follow-up care includes monitoring for complications and gradual return to activity. Healing time varies but typically ranges from several weeks to months, depending on the fracture type and patient factors.

Complications

• Infection, particularly with open fractures.
• Nonunion or delayed healing.
• Chronic pain or reduced mobility.
• Nerve or blood vessel damage in severe cases.

Lifestyle & Prevention

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

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, inability to bear weight, visible wound, or signs of infection (e.g., fever, increased redness, or drainage).

Tips for Medical Coders

Document the fracture type (IIIA, IIIB, or IIIC) and confirm routine healing status. Ensure the encounter is coded as subsequent, reflecting ongoing care for an established fracture. Include details of the open fracture classification and healing progress to support accurate coding.
