S92.116 Nondisplaced fracture of neck of unspecified talus

Name of the Condition

• Nondisplaced fracture of neck of unspecified talus

Summary

A nondisplaced fracture of the neck of the talus refers to a break in the narrow portion of the talus bone, where the bone fragments remain in 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. This type of fracture typically involves the neck region, which links the body of the talus to its head, and may affect joint surfaces depending on the severity of the injury.

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 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 studies, such as X-rays or CT scans, are typically used to confirm the fracture and evaluate its alignment. The nondisplaced nature of the fracture is determined by the absence of significant displacement of bone fragments.

Treatment Options

Treatment may include immobilization with a cast or boot to allow healing, followed by gradual weight-bearing and physical therapy to restore function. In some cases, surgical intervention may be necessary if the fracture is unstable or involves joint surfaces.

Prognosis and Follow-Up

With proper treatment, most nondisplaced fractures of the talus neck heal without complications. Follow-up care often involves monitoring for healing progress and assessing functional recovery. Long-term outcomes depend on the severity of the injury and adherence to rehabilitation protocols.

Complications

Potential complications include delayed healing, nonunion, or post-traumatic arthritis. In rare cases, avascular necrosis of the talus may occur due to disrupted blood supply.

Lifestyle & Prevention

• Wear appropriate footwear and protective gear during high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid sudden, high-impact movements that may stress the ankle joint.

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 or difficulty walking after initial treatment may also warrant further evaluation.

Tips for Medical Coders

When coding for a nondisplaced fracture of the neck of the talus, ensure the documentation specifies the fracture type (nondisplaced) and the anatomical location (neck of talus). Verify that the code S92.116 is used for unspecified talus and that laterality or displacement details are not present, as these would require different codes. Accurate documentation of the fracture's alignment and anatomical site is essential for correct coding.
