S92.113 Displaced fracture of neck of unspecified talus

Name of the Condition

• Displaced fracture of neck of unspecified talus

Summary

A displaced fracture of the neck of the unspecified talus involves a break in the narrow portion of the talus bone, with the bone fragments shifted out of their normal alignment. The talus is a critical bone in the ankle joint, connecting the foot to the lower leg and supporting weight-bearing and movement. Displacement may affect joint stability and healing.

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 type of 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 studies, such as X-rays or CT scans, are typically used to confirm the fracture and evaluate displacement. The provider will also assess the ankle joint for stability and alignment.

Treatment Options

Treatment depends on the severity of the displacement and joint involvement. Non-displaced fractures may be managed with immobilization (e.g., casting or bracing) and restricted weight-bearing. Displaced fractures often require surgical intervention to realign and stabilize the bone, followed by immobilization and physical therapy to restore function.

Prognosis and Follow-Up

Recovery time varies based on the fracture’s severity and treatment. Immobilization and physical therapy are common, with gradual return to weight-bearing as healing progresses. Regular follow-up appointments are necessary to monitor healing and adjust treatment plans. Most patients regain full function, but some may experience long-term stiffness or arthritis.

Complications

Potential complications include nonunion (failure to heal), malunion (improper healing), post-traumatic arthritis, chronic pain, or nerve damage. Infection or blood vessel injury may occur with surgical treatment.

Lifestyle & Prevention

• Wear appropriate footwear and protective gear during high-risk activities.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid sudden, high-impact movements that strain the ankle.
• Strengthen ankle muscles to improve stability and reduce injury risk.

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 critical to prevent complications and ensure proper treatment.

Tips for Medical Coders

Document the fracture’s displacement and specify the talus side (right/left) when known. For unspecified talus, use this code only when the side is not documented. Ensure clinical documentation supports the diagnosis and treatment to justify coding accuracy.
