S92.135 Nondisplaced fracture of posterior process of left talus

Name of the Condition

• Nondisplaced fracture of posterior process of left talus

Summary

A nondisplaced fracture of the posterior process of the left talus is a break in the small bony projection at the back of the talus bone on the left 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 can be involved in certain types of 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 and check for associated injuries to the ankle or surrounding structures.

Treatment Options

Treatment depends on the severity of the fracture and the patient's overall health. Nondisplaced fractures often heal with conservative management, including rest, ice, compression, and elevation (RICE), along with immobilization using a cast or boot. Pain management may involve over-the-counter or prescription medications. Physical therapy is often recommended to restore strength and mobility once healing progresses. In rare 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 proper treatment. Recovery time varies but typically ranges from several weeks to a few months, depending on the individual's age, overall health, and adherence to treatment. Follow-up appointments are important to monitor healing through imaging and assess progress. Physical therapy may be needed to regain full function, and patients should avoid high-impact activities until cleared by a healthcare provider.

Complications

Potential complications include delayed healing, nonunion (failure to heal), or malunion (healing in an abnormal position). There is also a risk of post-traumatic arthritis in the ankle joint, especially if the fracture affects joint surfaces. Nerve or blood vessel damage near the injury site is rare but possible. Chronic pain or stiffness may occur if the fracture is not properly managed.

Lifestyle & Prevention

To reduce the risk of injury, wear appropriate footwear and protective gear during sports or activities. Maintain good bone health through a balanced diet rich in calcium and vitamin D, and engage in regular weight-bearing exercise. Avoid activities that increase the risk of falls or ankle twists, and warm up properly before physical activity. If you have a history of ankle injuries, consider using supportive braces or orthotics.

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, warmth, fever). Persistent pain, limited mobility, or new deformity also warrant evaluation.

Tips for Medical Coders

This code represents a nondisplaced fracture of the posterior process of the left talus. Documentation should specify the location (left talus), the nature of the fracture (nondisplaced), and the affected structure (posterior process). Ensure the medical record includes details about the injury mechanism, clinical findings, and imaging results to support the diagnosis. For coding accuracy, verify that the fracture is not associated with displacement or other complications that would require a different code.
