S72.125K Nondisplaced fracture of lesser trochanter of left femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Nondisplaced fracture of lesser trochanter of left femur, subsequent encounter for closed fracture with nonunion

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 term "subsequent encounter" indicates this is a follow-up visit for a previously treated fracture, and "nonunion" means the fracture has not healed properly after an expected period. The fracture is classified as closed, meaning it does not penetrate the skin.

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. Nonunion may develop if the fracture does not heal due to inadequate immobilization, poor blood supply, or underlying health issues.

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.
• Smoking or poor nutrition, which can impair bone healing.

Symptoms

• Persistent pain in the hip or groin area, often worsened by movement.
• Swelling and bruising around the hip that may not resolve.
• Difficulty in weight-bearing or limping on the affected side.
• Possible instability or weakness in the hip joint.

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 check for nonunion. Additional tests, such as bone scans, may be ordered to evaluate bone healing.

Treatment Options

Treatment focuses on promoting healing and may include immobilization with a brace or cast, physical therapy to restore strength and mobility, and pain management. In some cases, surgery may be necessary to stabilize the fracture or stimulate bone growth.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and overall health. Regular follow-up visits and imaging are needed to monitor healing. Most patients can regain function with appropriate treatment, though recovery may take longer than for a healing fracture.

Complications

• Chronic pain or discomfort.
• Reduced mobility or permanent disability.
• Increased risk of future fractures due to weakened bone.
• Potential need for surgical intervention if nonunion persists.

Lifestyle & Prevention

• Maintain a diet rich in calcium and vitamin D to support bone health.
• Engage in weight-bearing exercises to strengthen bones.
• Use protective gear during high-impact activities.
• Avoid smoking and limit alcohol, which can impair bone healing.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or mobility declines. Prompt evaluation is important if new symptoms, such as fever or increased redness, develop, as these may indicate infection.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with nonunion. Include details about the fracture's status, treatment provided, and any imaging results. Ensure the code S72.125K is used for the left femur, nondisplaced lesser trochanter fracture with nonunion.
