Name of the Condition

• ICD Code: M96.671
• Common Name: Fracture of tibia or fibula following orthopedic implant.
• Medical Term: Periprosthetic tibial or fibular fracture.

Summary

This condition refers to a fracture of the tibia or fibula that occurs in the context of a prior orthopedic procedure involving the insertion of devices such as implants, joint prostheses, or bone plates specifically in the right leg. This is considered a type of periprosthetic fracture.

Causes

These fractures typically occur due to stress concentrations around the implant site, which may weaken the bone structure. Other causes include accidents, falls, or repeated stress in the presence of bone structural changes due to the implant.

Risk Factors

• Previous orthopedic surgery involving implants, prostheses, or bone plates.
• Osteoporosis or weakened bone density.
• Advanced age.
• Pre-existing conditions affecting bone health.

Symptoms

• Sudden pain in the right leg after trauma or stress.
• Swelling and bruising around the fracture site.
• Inability to bear weight on the affected leg.
• Noticeable deformity or abnormal movement in the leg.

Diagnosis

• Physical Examination: Initial assessment of symptoms and medical history.
• Imaging Tests: X-rays or CT scans to confirm the presence and extent of the fracture.

Treatment Options

• Immobilization: Use of casts or splints to stabilize the fracture.
• Surgery: In severe cases, surgical intervention may be required to repair the fracture and ensure implant stability.
• Physical Therapy: Post-treatment rehabilitation to restore function and mobility.

Prognosis and Follow-Up

• The prognosis depends on the fracture's severity and the individual’s overall health.
• Routine follow-up appointments are crucial to monitor healing progression and detect any complications.

Complications

• Non-union or delayed union of the fracture.
• Potential damage to the surrounding soft tissue or implant failure.
• Increased risk of infections.

Lifestyle & Prevention

• Maintain a healthy lifestyle with balanced nutrition to support bone health.
• Engage in exercises that enhance strength and balance to prevent falls.
• Regular check-ups post-implant surgery to monitor bone integrity.

When to Seek Professional Help

• Sudden, unexplained leg pain or inability to move the leg following trauma.
• Swelling, deformity, or symptoms of an infection (fever, redness) near the surgical site.

Tips for Medical Coders

• Ensure accurate documentation of the fracture’s relationship with the implant.
• Verify laterality (right leg) to avoid common coding errors.
• Cross-reference with surgery history for precise coding.
