S92.141 Displaced dome fracture of right talus

Name of the Condition

• Displaced dome fracture of right talus

Summary

A displaced dome fracture of the right talus involves a break in the dome (superior articular surface) of the talus bone on the right side, with the bone fragments shifted out of their normal alignment. This injury affects the ankle joint, potentially disrupting weight-bearing and movement. The talus connects the foot to the lower leg and is essential for joint stability and mobility.

Causes

Direct trauma to the ankle, such as falls, sports injuries, or motor vehicle accidents, is the primary cause. High-impact forces or twisting motions can lead to this fracture, particularly in activities involving sudden stops or changes in direction.

Risk Factors

• Participation in high-impact sports (e.g., basketball, soccer) or activities with a risk of ankle injury.
• Osteoporosis or other conditions that weaken bone density.
• Previous ankle or talus injuries.
• Improper footwear or inadequate protective gear during physical activities.

Symptoms

• Sudden, severe pain in the ankle or foot.
• Swelling and bruising around the injury site.
• Difficulty bearing weight or walking.
• Limited range of motion in the ankle joint.
• Possible deformity or abnormal positioning of the foot.

Diagnosis

A healthcare provider will perform a physical examination to assess pain, swelling, and mobility. Imaging tests, such as X-rays, CT scans, or MRIs, are typically used to confirm the fracture and evaluate its displacement and extent.

Treatment Options

• Immobilization with casts or splints to allow healing.
• Pain management through medication or other interventions.
• Physical therapy to restore mobility and strength post-healing.
• Surgical intervention may be necessary for severe displacement or joint involvement.

Prognosis and Follow-Up

Recovery depends on the severity of the fracture and treatment. Immobilization and physical therapy often lead to good outcomes, but severe cases may result in long-term mobility limitations. Follow-up imaging and clinical assessments are typically recommended to monitor healing and joint function.

Complications

• Post-traumatic arthritis due to joint surface damage.
• Chronic pain or stiffness.
• Nonunion or malunion of the fracture.
• Nerve or blood vessel injury in severe cases.

Lifestyle & Prevention

• Wear appropriate protective gear during high-risk activities.
• Use supportive footwear to stabilize the ankle.
• Maintain bone health through diet and exercise to reduce fracture risk.
• Avoid activities that increase ankle injury risk if previous injuries exist.

When to Seek Professional Help

Seek immediate medical attention if you experience severe ankle pain, swelling, or inability to bear weight after an injury. Prompt evaluation is important to assess for fracture and prevent complications.

Tips for Medical Coders

Document the specific location (right talus) and displacement (dome fracture) to accurately assign this code. Ensure clinical notes specify the fracture type and laterality to support coding. Verify that imaging or clinical findings confirm displacement, as this distinguishes the code from non-displaced or unspecified talus fractures.
