S92.146A Nondisplaced dome fracture of unspecified talus, initial encounter for closed fracture

Name of the Condition

• Nondisplaced dome fracture of unspecified talus, initial encounter for closed fracture

Summary

A nondisplaced dome fracture of the talus involves a break in the dome-shaped upper surface of the talus bone without displacement of the bone fragments. This injury affects the ankle joint and can impact weight-bearing and mobility. The talus connects the foot to the lower leg and is essential for joint stability and movement.

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 alignment.

Treatment Options

Treatment may include immobilization with a cast or brace to allow healing, pain management, and physical therapy to restore function. Surgical intervention is generally not required for nondisplaced fractures but may be considered if complications arise.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and rehabilitation. Follow-up care typically involves monitoring for healing progress and gradual return to weight-bearing activities as tolerated.

Complications

Potential complications include delayed healing, arthritis in the ankle joint, or persistent pain. In rare cases, avascular necrosis (loss of blood supply to the bone) may occur.

Lifestyle & Prevention

• Wear appropriate footwear and protective gear during sports or high-risk activities.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid activities that increase the risk of ankle injury, such as uneven terrain or excessive twisting motions.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, or visible deformity after an injury. Persistent pain or swelling after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the fracture as nondisplaced and specify the initial encounter for a closed fracture. Ensure the talus is identified as the affected bone and note the absence of displacement to support accurate coding.
