S82.123F Displaced fracture of lateral condyle of unspecified tibia, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

Displaced fracture of lateral condyle of unspecified tibia, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Summary

This condition involves a displaced fracture of the lateral condyle of the tibia, a bony prominence on the outer side of the upper tibia that contributes to knee joint stability. The fracture is displaced, meaning the bone fragments are out of their normal alignment. This is a subsequent encounter for an open fracture classified as type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination. The fracture is healing routinely, with no complications noted.

Causes

Traumatic injury to the knee, such as falls, sports-related impacts, or motor vehicle accidents, is the primary cause. Direct force to the lateral knee or twisting injuries can lead to this fracture. The open nature of the fracture suggests the injury penetrated the skin, exposing the bone to the environment.

Risk Factors

• Participation in high-impact or contact sports.
• Osteoporosis or other bone-weakening conditions.
• Previous knee injuries or surgeries.
• Advanced age, which may reduce bone density.
• Activities with a high risk of falls or direct trauma to the knee.

Symptoms

• Pain, swelling, and tenderness localized to the lateral knee.
• Difficulty bearing weight on the affected leg.
• Possible visible deformity or misalignment.
• Bruising or discoloration around the injury site.
• Open wound at the fracture site (for open fractures).

Diagnosis

Physical examination to assess pain, swelling, and joint stability. Imaging tests, such as X-rays or CT scans, to evaluate fracture type, displacement, and joint involvement. Assessment of the open wound for contamination and soft tissue damage.

Treatment Options

• Surgical intervention to realign and stabilize the fracture with plates, screws, or pins.
• Immobilization with a cast or brace to support healing.
• Wound care for open fractures to prevent infection.
• Physical therapy to restore joint function and strength.

Prognosis and Follow-Up

With proper treatment, most fractures heal routinely, and patients can regain normal knee function. Follow-up appointments are necessary to monitor healing progress and adjust treatment as needed. Recovery time varies depending on fracture severity and patient health.

Complications

• Infection at the open wound site.
• Nonunion or malunion of the fracture.
• Joint stiffness or reduced range of motion.
• Nerve or blood vessel damage.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid activities that increase fall risk.
• Follow post-injury care instructions to support healing.

When to Seek Professional Help

Seek immediate medical attention for severe pain, swelling, or deformity. Contact a healthcare provider if symptoms worsen, or if there are signs of infection, such as fever or increased redness.

Tips for Medical Coders

Document the fracture type (IIIA, IIIB, or IIIC) and confirm routine healing. Include details on the open wound and any treatment provided. Ensure the encounter is classified as subsequent to reflect ongoing care.
