S72.324P Nondisplaced transverse fracture of shaft of right femur, subsequent encounter for closed fracture with malunion

Name of the Condition

• Nondisplaced Transverse Fracture of Shaft of Right Femur, Subsequent Encounter for Closed Fracture with Malunion (ICD-10 Code: S72.324P)

Summary

A nondisplaced transverse fracture of the shaft of the right femur is a break in the long, central portion of the right thigh bone, where the fracture line runs horizontally across the bone and the bone fragments remain aligned. This type of fracture involves the diaphysis (main structural part) of the femur. The subsequent encounter indicates this is a follow-up visit for a closed fracture (no open wound) that has healed with malunion, meaning the bone has united but not in its normal anatomical position.

Causes

Such fractures typically result from high-impact trauma, such as motor vehicle accidents, falls from significant heights, or direct blows to the thigh. Rotational or axial loading injuries (e.g., during sports or industrial accidents) can also cause this type of break. Malunion may occur if the fracture was not properly aligned during initial healing or if the bone fragments shifted during the healing process.

Risk Factors

• Participation in high-impact sports or activities.
• Osteoporosis or other bone-weakening conditions.
• Advanced age, due to decreased bone density.
• Prior history of fractures or bone abnormalities.
• Trauma or accidents involving significant force.

Symptoms

• Persistent pain or discomfort in the right thigh, even after initial healing.
• Visible or palpable deformity at the fracture site due to malunion.
• Reduced range of motion or functional impairment of the affected leg.
• Possible gait abnormalities or limping.

Diagnosis

Physical examination to assess alignment, pain, and functional limitations. Imaging tests such as X-rays or CT scans are used to confirm malunion and evaluate the extent of bone healing. The diagnosis is based on clinical findings and radiographic evidence of the fracture site.

Treatment Options

Treatment may include physical therapy to improve strength and mobility, pain management, and possibly orthopedic interventions if the malunion causes significant functional impairment. Surgical correction (e.g., osteotomy) may be considered in severe cases to realign the bone.

Prognosis and Follow-Up

Prognosis depends on the degree of malunion and the patient’s overall health. Most patients can achieve functional recovery with appropriate treatment, though some may experience long-term limitations. Regular follow-up visits are necessary to monitor healing and adjust treatment plans as needed.

Complications

• Chronic pain or discomfort.
• Reduced mobility or functional impairment.
• Increased risk of future fractures due to altered bone structure.
• Potential need for surgical intervention to correct malunion.

Lifestyle & Prevention

• Engage in low-impact exercises to maintain bone health and strength.
• Use protective gear during high-risk activities to prevent trauma.
• Ensure adequate calcium and vitamin D intake to support bone health.
• Avoid activities that place excessive stress on the affected leg until cleared by a healthcare provider.

When to Seek Professional Help

Seek medical attention if you experience worsening pain, new deformity, or significant functional decline in the affected leg. Prompt evaluation is important if you notice signs of infection, such as redness, swelling, or fever, at the fracture site.

Tips for Medical Coders

Document the presence of malunion and the subsequent encounter status clearly in the medical record. Ensure the fracture is classified as closed and specify the right femur. The code S72.324P requires confirmation of malunion and subsequent care for the closed fracture.
