S52.342 Displaced spiral fracture of shaft of radius, left arm

Name of the Condition

Displaced spiral fracture of shaft of radius, left arm
ICD-10 Code: S52.342

Summary

A displaced spiral fracture of the shaft of the radius is a break in the long, outer bone of the forearm (radius) between the elbow and wrist, where the bone fragments are twisted and separated from their normal alignment. This injury typically results from rotational forces and may affect arm function depending on the degree of displacement and associated soft tissue damage.

Causes

This fracture commonly occurs due to direct trauma, such as falls onto an outstretched arm, twisting injuries to the wrist or forearm, or high-impact events like motor vehicle collisions. Sports injuries or accidents involving sudden rotational forces can also cause the bone to break in a spiral pattern.

Risk Factors

• Participation in contact sports or activities with a high risk of falls
• Osteoporosis or weakened bone density
• Advanced age, which increases fracture susceptibility
• Previous forearm or wrist injuries
• Occupations or hobbies involving repetitive stress or heavy lifting

Symptoms

• Sudden, severe pain at the injury site
• Swelling, bruising, or deformity of the forearm
• Inability to move the wrist or forearm
• Visible bone protrusion through the skin (in open fractures)
• Numbness or tingling in the hand or fingers

Diagnosis

Diagnosis typically involves a physical examination to assess pain, swelling, and deformity, followed by imaging studies such as X-rays to confirm the fracture type, displacement, and alignment. Additional imaging like CT scans may be used for complex cases to evaluate fracture details and associated injuries.

Treatment Options

Treatment depends on fracture stability and displacement. Stable fractures may be managed with immobilization using a cast or splint. Displaced or unstable fractures often require closed reduction (realignment) or surgical intervention with internal fixation (plates, screws) to restore alignment and stability. Pain management and physical therapy are common adjuncts.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment, though recovery time varies based on fracture severity and patient factors. Follow-up appointments monitor healing, alignment, and functional recovery. Physical therapy may be recommended to restore strength and range of motion.

Complications

Potential complications include nonunion (failure to heal), malunion (improper healing), nerve or blood vessel damage, infection (if open fracture), and long-term stiffness or weakness. Early intervention reduces these risks.

Lifestyle & Prevention

Preventive measures include using protective gear during high-risk activities, maintaining bone health through diet and exercise, and avoiding falls by modifying environments (e.g., removing tripping hazards). Strengthening forearm muscles may also reduce injury risk.

When to Seek Professional Help

Seek immediate medical attention for severe pain, deformity, inability to move the arm, visible bone protrusion, or signs of nerve damage (numbness, tingling). Delayed care may worsen outcomes.

Tips for Medical Coders

Document the fracture's displacement, laterality (left arm), and any associated injuries. Ensure clinical notes specify the fracture pattern (spiral) and alignment status to support accurate coding. Include details on treatment approach (conservative vs. surgical) if relevant to the encounter.
