S52.5 Fracture of lower end of radius

Name of the Condition

• Fracture of lower end of radius

Summary

A fracture of the lower end of the radius involves a break in the distal portion of the radius bone, which is part of the forearm near the wrist. This type of fracture is commonly referred to as a distal radial fracture and may involve varying degrees of bone displacement or soft tissue involvement.

Causes

Typically results from trauma such as a fall onto an outstretched hand, direct impact to the wrist, or high-force injuries like motor vehicle accidents. The mechanism often involves axial loading or bending forces applied to the wrist.

Risk Factors

• Increased likelihood with activities prone to falls, such as sports or occupational hazards.
• Higher risk in older adults due to age-related bone density loss (osteoporosis).
• Greater susceptibility in postmenopausal women and individuals with conditions affecting bone strength.

Symptoms

• Pain and swelling around the wrist.
• Difficulty or inability to move the wrist or forearm.
• Bruising, tenderness, or visible deformity in the affected area.
• Numbness or tingling in the hand or fingers (possible nerve involvement).

Diagnosis

Physical examination to assess pain, swelling, deformity, and range of motion. Imaging tests, primarily X-rays, to determine the exact location, type, and severity of the fracture. Additional imaging (e.g., CT scans) may be used for complex cases.

Treatment Options

• Immobilization using a cast, splint, or brace for stable, non-displaced fractures.
• Closed reduction (manual realignment) for displaced fractures, often followed by casting.
• Surgical intervention (e.g., internal fixation with pins, plates, or screws) for unstable, severely displaced, or open fractures.
• Rehabilitation to restore strength and mobility after healing.

Prognosis and Follow-Up

Most fractures heal within 6–12 weeks with appropriate treatment, but recovery time varies based on fracture severity and patient factors. Follow-up appointments monitor healing progress, typically with repeat imaging. Long-term outcomes depend on fracture type, treatment, and adherence to rehabilitation.

Complications

• Potential for malunion (improper healing) or nonunion (failure to heal).
• Nerve or blood vessel damage, leading to numbness, weakness, or circulation issues.
• Post-traumatic arthritis or stiffness in the wrist joint.
• Infection (more common with open fractures).

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, work).
• Maintain bone health through adequate calcium, vitamin D, and weight-bearing exercise.
• Fall prevention strategies for older adults (e.g., home modifications, balance training).

When to Seek Professional Help

• Severe pain, swelling, or deformity after injury.
• Inability to move the wrist or forearm.
• Numbness, tingling, or coldness in the hand or fingers.
• Open wound or visible bone protrusion (signs of an open fracture).

Tips for Medical Coders

• Document the fracture type (e.g., displaced, non-displaced, open/closed) and treatment encounter (initial, subsequent, sequela) to ensure accurate coding.
• Specify laterality (right/left/unspecified) and any associated complications (e.g., nerve injury) when applicable.
• Use additional codes for external causes (e.g., falls) or comorbidities (e.g., osteoporosis) as needed for complete documentation.
