S82.433A Displaced oblique fracture of shaft of unspecified fibula, initial encounter for closed fracture

Name of the Condition

• Displaced oblique fracture of shaft of unspecified fibula, initial encounter for closed fracture

Summary

This condition involves a break in the shaft of the fibula, one of the two long bones in the lower leg. The fracture is oblique (at an angle) and displaced, meaning the bone fragments have shifted out of their normal alignment. It is classified as a closed fracture, with no open wound or communication to the fracture site, and is documented as the initial encounter for this injury.

Causes

Direct trauma to the lower leg, such as from falls, sports injuries, or motor vehicle accidents. Twisting injuries during physical activity can also lead to this type of fracture.

Risk Factors

• Engaging in high-impact sports or activities.
• Osteoporosis or weakened bone density.
• Previous fractures or bone-related conditions.

Symptoms

• Severe pain in the lower leg.
• Swelling and bruising around the fracture site.
• Inability to bear weight on the injured leg.
• Visible deformity if the displacement is significant.

Diagnosis

Physical examination to assess tenderness, swelling, and deformity. Imaging tests, such as X-rays, to confirm the fracture type, displacement, and whether the fracture is closed.

Treatment Options

• Immobilization with a cast or splint to maintain alignment during healing.
• Pain management with medications.
• Surgical intervention may be necessary for severe displacement to realign and fixate the bone.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment, though recovery time depends on fracture severity and patient factors. Follow-up care typically includes monitoring for healing and rehabilitation to restore function.

Complications

• Delayed healing or nonunion of the fracture.
• Malunion, where the bone heals in an abnormal position.
• Nerve or vascular damage in severe cases.
• Chronic pain or stiffness.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid activities that increase fall or injury risk.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., redness, warmth, or drainage) at the fracture site.

Tips for Medical Coders

Document the fracture as displaced and oblique, specify the shaft of the fibula (unspecified side), and confirm it is a closed fracture with no open wound. Ensure the encounter is coded as initial for accurate reporting.
