S92.144 Nondisplaced dome fracture of right talus

Name of the Condition

• Nondisplaced dome fracture of right talus

Summary

A nondisplaced dome fracture of the right talus is a break in the dome-shaped upper surface of the talus bone on the right side, where the bone fragments remain in 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 critical for ankle function.

Causes

Direct trauma to the ankle, such as falls, sports injuries, or motor vehicle accidents, is the most common cause. High-impact forces or twisting motions can also lead to dome fractures, 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 alignment.

Treatment Options

Treatment depends on the severity and may include immobilization with a cast or boot, pain management, and physical therapy. Severe cases may require surgery to stabilize the fracture.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper treatment, but recovery time varies. Follow-up care often includes monitoring for healing and gradual return to activity, with physical therapy to restore strength and mobility.

Complications

Potential complications include delayed healing, arthritis in the ankle joint, or chronic pain. In rare cases, infection or nerve damage may occur.

Lifestyle & Prevention

• Wear supportive footwear during physical activities.
• Use protective gear (e.g., ankle braces) in high-risk sports.
• Maintain bone health through proper nutrition and exercise.
• Avoid activities that increase ankle injury risk if prone to falls or instability.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., fever, increased swelling).

Tips for Medical Coders

Document the nondisplaced nature of the fracture and specify the right talus. Ensure clinical notes support the diagnosis and include details on imaging or treatment to justify code assignment.
