S32.611 Displaced avulsion fracture of right ischium

Name of the Condition

• Displaced avulsion fracture of right ischium

Summary

This condition involves a displaced avulsion fracture of the right ischium, a bone in the pelvis. Avulsion fractures occur when a tendon or ligament pulls a piece of bone away from its attachment site. The ischium supports body weight during sitting, and displacement means the fractured bone fragment has moved from its original position. Severity and treatment depend on the size of the displaced fragment and associated injuries.

Causes

Traumatic events such as falls, motor vehicle accidents, or direct blows to the pelvis are common causes. Avulsion fractures often result from sudden muscle contractions or overstretching, particularly in athletes or during high-impact activities.

Risk Factors

• Participation in sports or activities with sudden forceful movements (e.g., sprinting, jumping).
• Previous pelvic or ischial injuries.
• Chronic conditions affecting bone strength, such as osteoporosis.
• Age-related bone density loss.

Symptoms

• Sharp pain in the right buttock or pelvic region, often worsened by movement or pressure.
• Swelling, bruising, or tenderness over the affected area.
• Difficulty sitting, standing, or bearing weight on the right side.
• Possible nerve-related symptoms (e.g., numbness, tingling) if nearby nerves are involved.

Diagnosis

Physical examination to assess pain, swelling, and functional limitations. Imaging studies, including X-rays, CT scans, or MRI, to visualize the fracture and assess displacement. Additional tests may evaluate associated soft tissue or nerve damage.

Treatment Options

• Rest and activity modification to allow healing.
• Pain management with medications or ice.
• Physical therapy to restore strength and mobility.
• Surgical intervention for severe displacement or unstable fragments.
• Immobilization with a brace or crutches as needed.

Prognosis and Follow-Up

Most cases heal with conservative management, but recovery time varies. Follow-up imaging may be used to monitor healing. Long-term outcomes depend on fracture severity, treatment, and adherence to rehabilitation.

Complications

• Chronic pain or discomfort.
• Nonunion or malunion of the fracture.
• Nerve or vascular damage from displacement.
• Reduced mobility or functional limitations.

Lifestyle & Prevention

• Warm up and stretch before physical activity.
• Use proper techniques in sports or exercise.
• Maintain bone health through diet and exercise.
• Avoid high-risk activities if prone to pelvic injuries.

When to Seek Professional Help

Seek care if pain is severe, worsens, or interferes with daily activities. Immediate attention is needed for signs of nerve damage (e.g., numbness, weakness) or if the injury results from a high-impact event.

Tips for Medical Coders

Document the fracture as displaced and specify the right ischium. Include details on avulsion mechanism, displacement extent, and associated injuries. Ensure clinical correlation with imaging and physical exam findings.
