S52.336A Nondisplaced oblique fracture of shaft of unspecified radius, initial encounter for closed fracture

Name of the Condition

Nondisplaced oblique fracture of shaft of unspecified radius, initial encounter for closed fracture
ICD-10 Code: S52.336A

Summary

A nondisplaced oblique 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 fracture line runs at an angle across the bone and the bone fragments remain aligned. This type of fracture is typically closed (skin intact) and results from trauma. Treatment focuses on immobilization and monitoring, as the fracture is stable and unlikely to require surgical intervention.

Causes

This fracture commonly occurs due to direct trauma, such as falls onto an outstretched arm, direct blows to the forearm, or accidents involving twisting forces at the wrist or elbow. High-impact events like motor vehicle collisions or sports injuries can also cause the bone to break in an oblique 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
• Numbness or tingling in the hand or fingers (if nerve involvement occurs)

Diagnosis

Diagnosis is confirmed through clinical evaluation and imaging. A physical exam assesses pain, swelling, and range of motion. X-rays are typically used to visualize the fracture, confirm it is oblique and nondisplaced, and rule out associated injuries. Additional imaging (e.g., CT or MRI) may be ordered if soft tissue damage or joint involvement is suspected.

Treatment Options

Treatment usually involves immobilization with a cast or splint to stabilize the fracture and allow healing. Pain management with over-the-counter or prescription medications may be recommended. Follow-up appointments monitor healing progress, and physical therapy may be prescribed to restore strength and mobility once the fracture is stable.

Prognosis and Follow-Up

Prognosis is generally favorable for nondisplaced fractures, with most patients recovering fully within 6–12 weeks. Follow-up care includes regular imaging to ensure proper healing and adjustments to the treatment plan if needed. Full return to normal activities is expected once the fracture is healed and strength is restored.

Complications

While rare, potential complications include malunion (improper healing), nonunion (failure to heal), or nerve injury. Infection may occur if the fracture becomes open, though this is not applicable to closed fractures. Persistent pain or stiffness may require further intervention.

Lifestyle & Prevention

To reduce fracture risk, maintain bone health through a diet rich in calcium and vitamin D, and engage in weight-bearing exercise. Use protective gear during sports or activities with fall risks. Avoid repetitive heavy lifting or high-impact motions that strain the forearm.

When to Seek Professional Help

Seek immediate medical attention if severe pain, swelling, or deformity occurs after an injury. Contact a healthcare provider if symptoms worsen, or if numbness, tingling, or loss of function in the hand develops, as these may indicate nerve or vascular involvement.

Tips for Medical Coders

Use code S52.336A for a nondisplaced oblique fracture of the radius shaft, unspecified side, with an initial encounter for a closed fracture. Document the fracture type (oblique, nondisplaced), location (shaft of radius), laterality (unspecified), and encounter type (initial, closed) to ensure accurate coding. Verify that the fracture is not displaced or open, as this would require different codes.
