S92.146S Nondisplaced dome fracture of unspecified talus, sequela

Name of the Condition

• Nondisplaced dome fracture of unspecified talus, sequela

Summary

A nondisplaced dome fracture of the talus, sequela, refers to a healed or residual condition resulting from a prior nondisplaced fracture of the dome-shaped upper surface of the talus bone. This sequela represents the long-term effects of the original injury, which may include persistent symptoms or structural changes in the ankle joint. The talus connects the foot to the lower leg and is essential for weight-bearing and mobility, so residual issues can impact function.

Causes

The sequela arises from a previous nondisplaced dome fracture of the talus, typically caused by direct trauma such as falls, sports injuries, or motor vehicle accidents. High-impact forces or twisting motions during the initial injury can lead to the fracture, and the sequela reflects the body’s healing response or incomplete resolution of the original injury.

Risk Factors

• History of talus or ankle injuries, particularly fractures.
• Inadequate healing or rehabilitation following the initial fracture.
• Underlying conditions affecting bone or joint health (e.g., osteoporosis).
• Activities that stress the ankle joint, potentially exacerbating residual symptoms.

Symptoms

• Chronic or intermittent pain in the ankle or foot.
• Reduced range of motion or stiffness in the ankle joint.
• Difficulty with weight-bearing or walking, especially on uneven surfaces.
• Swelling or tenderness at the injury site.
• Possible instability or weakness in the ankle.

Diagnosis

A healthcare provider will evaluate the patient’s history of the original fracture and assess current symptoms, including pain, mobility, and functional limitations. Imaging studies, such as X-rays or MRI, may be used to identify residual bone changes, joint alignment, or signs of arthritis. Physical examination focuses on joint stability and range of motion.

Treatment Options

Treatment depends on the severity of symptoms and functional impact. Conservative measures may include physical therapy to improve strength and mobility, pain management, or orthotic devices. In cases of significant residual dysfunction, surgical intervention to address joint alignment or remove loose fragments may be considered.

Prognosis and Follow-Up

Prognosis varies based on the extent of the sequela and the patient’s response to treatment. Many individuals experience improved function with rehabilitation, though some may have persistent limitations. Regular follow-up appointments monitor symptoms, joint health, and the effectiveness of interventions.

Complications

• Chronic pain or arthritis in the ankle joint.
• Reduced mobility or instability.
• Difficulty returning to high-impact activities.
• Potential need for further intervention if symptoms worsen.

Lifestyle & Prevention

• Engage in low-impact exercises to maintain joint health.
• Use supportive footwear to reduce stress on the ankle.
• Avoid activities that increase the risk of re-injury.
• Follow rehabilitation guidelines to optimize recovery.

When to Seek Professional Help

Seek care if symptoms worsen, new pain or swelling develops, or functional limitations interfere with daily activities. Prompt evaluation is important if there are signs of infection or if the ankle becomes unstable.

Tips for Medical Coders

This code is used for a sequela (late effect) of a nondisplaced dome fracture of the talus. Document the relationship to the original injury, including the time elapsed since the fracture and any residual symptoms or structural changes. Ensure the diagnosis supports the use of a sequela code and that the fracture is confirmed as nondisplaced and involving the talus dome.
