S82.422P Displaced transverse fracture of shaft of left fibula, subsequent encounter for closed fracture with malunion

Name of the Condition

• Displaced transverse fracture of shaft of left fibula, subsequent encounter for closed fracture with malunion
• ICD-10 Code: S82.422P

Summary

A displaced transverse fracture of the shaft of the left fibula is a break in the long, thin bone on the lateral side of the lower leg, where the bone fragments are separated and misaligned. This is a subsequent encounter for a closed fracture with malunion, meaning the fracture has healed in a non-anatomical position, and the skin remains intact. The transverse pattern indicates the fracture line runs horizontally across the bone.

Causes

Most commonly caused by direct trauma or high-impact forces to the leg, such as falls, sports injuries, or motor vehicle accidents. Twisting motions or sudden impacts can also lead to this type of fracture.

Risk Factors

• Participation in contact sports or high-impact activities.
• Osteoporosis or reduced bone density, which increases fragility.
• Advanced age, which may weaken bone strength.
• Previous leg injuries or surgeries.

Symptoms

• Pain and swelling in the lower leg.
• Difficulty bearing weight on the affected leg.
• Bruising or tenderness around the injured area.
• Visible deformity or instability of the leg structure.
• Possible functional limitations due to malunion.

Diagnosis

Diagnosis involves a physical examination by a healthcare professional to assess tenderness, swelling, and deformity. Imaging tests, such as X-rays, are typically used to confirm the fracture, evaluate the degree of displacement, and assess for malunion.

Treatment Options

Treatment may include pain management, physical therapy to improve mobility, and orthopedic interventions if the malunion causes significant functional impairment. Surgical correction may be considered in severe cases.

Prognosis and Follow-Up

Prognosis depends on the severity of the malunion and the patient's overall health. Follow-up care often involves monitoring for complications and ongoing rehabilitation to restore function.

Complications

• Chronic pain or discomfort.
• Reduced mobility or range of motion.
• Increased risk of future fractures.
• Potential need for surgical intervention.

Lifestyle & Prevention

• Engage in regular weight-bearing exercises to maintain bone strength.
• Use protective gear during high-risk activities.
• Ensure adequate calcium and vitamin D intake to support bone health.
• Avoid activities that increase the risk of falls or leg injuries.

When to Seek Professional Help

Seek medical attention if you experience persistent pain, swelling, or difficulty bearing weight, or if you notice worsening deformity or functional limitations.

Tips for Medical Coders

Document the presence of malunion and confirm the fracture is closed. Ensure the encounter is coded as subsequent, reflecting ongoing care for the healed fracture with malunion. Include details about the fracture's impact on function and any treatment provided.
