S82.031 Displaced transverse fracture of right patella

Name of the Condition

• Displaced transverse fracture of right patella

Summary

This condition involves a horizontal break in the right kneecap (patella) where the bone fragments are not aligned. The transverse fracture pattern typically results from direct trauma, and displacement indicates the bone pieces have shifted from their normal position.

Causes

Direct trauma to the knee, such as a fall onto the kneecap, a blow from an object, or a forceful contraction of the quadriceps muscle. High-impact injuries, like those from sports or motor vehicle accidents, are common triggers.

Risk Factors

• Participation in activities with a high risk of knee injury, such as contact sports or skiing.
• Osteoporosis or other bone-weakening conditions.
• Previous knee injuries or surgeries.
• Advanced age, which may reduce bone density.

Symptoms

• Sudden, severe pain in the right knee.
• Swelling and bruising around the kneecap.
• Inability to straighten the knee or bear weight.
• Visible deformity or a gap in the kneecap area.
• A "popping" sensation at the time of injury.

Diagnosis

A physical examination to assess knee movement, swelling, and tenderness. Imaging studies, typically X-rays, to confirm the fracture and evaluate bone alignment. In some cases, a CT scan may be used to assess complex fractures or displacement.

Treatment Options

• Conservative management: Immobilization with a brace or cast to allow healing.
• Surgical intervention: May be necessary to realign and stabilize the bone fragments, especially if displacement is significant.
• Rehabilitation: Physical therapy to restore movement and strength after immobilization or surgery.

Prognosis and Follow-Up

Most patients recover well with appropriate treatment, though recovery time varies. Follow-up appointments are typically scheduled to monitor healing and adjust treatment plans as needed. Complications, such as arthritis or stiffness, may occur in some cases.

Complications

• Nonunion or delayed healing of the fracture.
• Post-traumatic arthritis in the knee joint.
• Stiffness or reduced range of motion.
• Infection (if surgery is performed).

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by using assistive devices if balance is impaired.
• Warm up properly before physical activity to reduce injury risk.

When to Seek Professional Help

Seek immediate medical attention if you experience severe knee pain, swelling, or an inability to bear weight after an injury. Persistent pain, fever, or signs of infection (e.g., redness, drainage) after treatment also warrant evaluation.

Tips for Medical Coders

Document the fracture type (transverse), displacement, and laterality (right) clearly in the medical record. Ensure the code S82.031 is used only when the fracture is confirmed as displaced and transverse, with no additional details (e.g., open vs. closed) specified. Verify that the documentation supports the specific characteristics of this code to avoid miscoding.
