S92.134 Nondisplaced fracture of posterior process of right talus

Name of the Condition

• Nondisplaced fracture of posterior process of right talus

Summary

A nondisplaced fracture of the posterior process of the right talus is a break in the small bony projection at the back of the talus bone on the right side, where the bone fragments remain in their normal alignment. The talus is a key bone in the ankle joint, and this injury can affect weight-bearing and movement. The posterior process is a small but important structure that may be involved in certain ankle injuries.

Causes

Direct trauma to the ankle, such as falls, sports injuries, or accidents, is the most common cause. High-impact forces or twisting motions can also lead to fractures of the posterior process, 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 or CT scans, are typically used to confirm the fracture and determine if it is nondisplaced. The provider will evaluate the alignment of the bone fragments to guide treatment decisions.

Treatment Options

Treatment may include immobilization with a cast or boot to allow healing, pain management, and activity modification. Physical therapy may be recommended to restore strength and mobility once the fracture has healed. In some cases, surgery may be considered if the fracture does not heal properly or causes persistent symptoms.

Prognosis and Follow-Up

Most nondisplaced fractures of the posterior process of the talus heal well with conservative treatment. Recovery time varies but typically ranges from several weeks to a few months. Follow-up appointments with a healthcare provider are important to monitor healing and adjust treatment as needed. Full return to normal activities is usually possible with proper care.

Complications

Potential complications include delayed healing, nonunion (failure to heal), or persistent pain. There is also a risk of arthritis in the ankle joint over time, especially if the fracture affects joint alignment or stability. Nerve or blood vessel damage near the injury site is rare but possible.

Lifestyle & Prevention

To reduce the risk of injury, 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 falls or ankle twists. If you have a history of ankle injuries, consider strengthening exercises to improve stability.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or inability to bear weight after an injury. Contact a healthcare provider if symptoms worsen or do not improve with initial treatment, or if you notice signs of infection (e.g., redness, fever). Persistent pain or limited mobility after healing should also be evaluated.

Tips for Medical Coders

When coding for a nondisplaced fracture of the posterior process of the right talus, use the ICD-10-CM code S92.134. Ensure documentation specifies the location (right talus), the structure involved (posterior process), and the fracture type (nondisplaced). Include details about the mechanism of injury, imaging findings, and treatment plan to support accurate coding and billing.
