S82.466 Nondisplaced segmental fracture of shaft of unspecified fibula

Name of the Condition

• Nondisplaced segmental fracture of shaft of unspecified fibula
• ICD-10 Code: S82.466

Summary

A nondisplaced segmental fracture of the shaft of the unspecified fibula is a break in the long, thin bone of the lower leg that involves two separate fracture sites along the same bone segment, creating a "floating" middle fragment. The bone fragments remain in their normal alignment, and the injury typically affects the middle portion of the fibula. This type of fracture is less severe than displaced fractures but still requires medical attention to ensure proper healing.

Causes

Most commonly caused by high-energy trauma, such as motor vehicle accidents, falls from significant height, or direct impact to the leg. Twisting injuries or severe rotational forces can also lead to this type of fracture.

Risk Factors

• Participation in high-impact sports or activities with risk of falls.
• Osteoporosis or reduced bone density, which increases fragility.
• Advanced age, which may weaken bone strength.
• Previous leg injuries or surgeries that compromise bone integrity.

Symptoms

• Intense pain and swelling in the lower leg.
• Difficulty bearing weight on the affected leg.
• Bruising or tenderness around the injured area.
• Possible deformity or instability of the leg structure.
• Numbness or tingling if nerve involvement occurs.

Diagnosis

Diagnosis involves a physical examination by a healthcare professional to assess tenderness, swelling, and deformity. Imaging tests, such as X-rays, are typically used to confirm the fracture and determine its extent and alignment. Additional imaging, like CT scans, may be ordered if more detailed visualization is needed.

Treatment Options

• Immobilization with a cast or brace to stabilize the fracture and promote healing.
• Pain management with medications, as needed.
• Physical therapy to restore strength and mobility once healing progresses.
• Surgical intervention is rarely required for nondisplaced fractures but may be considered if stability is a concern.

Prognosis and Follow-Up

Prognosis is generally favorable for nondisplaced fractures, with most patients recovering fully with proper treatment. Follow-up appointments are necessary to monitor healing, typically with repeat imaging at 4-6 weeks. Full weight-bearing and return to normal activities may take several months, depending on the individual's healing rate.

Complications

• Delayed healing or nonunion of the fracture.
• Malunion, where the bone heals in an abnormal position.
• Nerve or blood vessel damage, though rare in nondisplaced fractures.
• Chronic pain or stiffness in the affected leg.

Lifestyle & Prevention

• Wear appropriate protective gear during high-risk activities.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Avoid activities that increase fall risk, especially for older adults.
• Engage in regular weight-bearing exercises to strengthen bones.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, visible deformity, or signs of nerve damage (e.g., numbness, tingling). Follow up with a healthcare provider if pain worsens, swelling persists, or you notice any new symptoms during recovery.

Tips for Medical Coders

When coding S82.466, ensure documentation specifies the fracture is segmental (two separate fracture sites) and nondisplaced. Note the unspecified fibula designation, as laterality (right/left) or additional details (e.g., open vs. closed) are not provided. Verify that the injury is confined to the shaft of the fibula and not involving other structures. Accurate documentation of the fracture type and alignment is critical for correct code assignment.
