S92.11 Fracture of neck of talus

Name of the Condition

• Fracture of neck of talus

Summary

A fracture of the neck of the talus refers to a break in the narrow portion of the talus bone, which connects the body of the talus to its head. This injury can disrupt the ankle joint and affect weight-bearing and movement. The talus is a critical bone in the ankle, and fractures in this region may involve joint surfaces or displacement, depending on the severity of the trauma.

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 fractures of the talus neck, 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 extent, including any displacement or involvement of joint surfaces.

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 displaced fractures or those involving joint surfaces.

Prognosis and Follow-Up

Recovery depends on the severity of the fracture and treatment. Immobilization and physical therapy are common, with healing typically taking several weeks to months. Follow-up imaging may be required to monitor healing, and long-term mobility or arthritis risk may be assessed.

Complications

• Nonunion or delayed healing of the fracture.
• Post-traumatic arthritis in the ankle joint.
• Chronic pain or stiffness.
• Nerve or vascular damage in severe cases.

Lifestyle & Prevention

• Wear appropriate footwear and protective gear during high-impact activities.
• Maintain bone health through diet and exercise to reduce fracture risk.
• Avoid activities that increase ankle injury risk if you have a history of ankle problems.

When to Seek Professional Help

Seek immediate medical attention if you experience severe ankle pain, swelling, or inability to bear weight after an injury. Persistent pain, deformity, or signs of infection (e.g., redness, fever) also warrant evaluation.

Tips for Medical Coders

Document the fracture as "Fracture of neck of talus" (S92.11) when the specific location is confirmed. Ensure clinical notes specify the anatomical site (neck of talus) and any associated details (e.g., displacement, open vs. closed) to support accurate coding.
