S52.335A Nondisplaced oblique fracture of shaft of left radius, initial encounter for closed fracture

Name of the Condition

Nondisplaced oblique fracture of shaft of left radius, initial encounter for closed fracture
ICD-10 Code: S52.335A

Summary

A nondisplaced oblique fracture of the shaft of the left 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 stabilizing the bone to promote healing, as the lack of displacement often allows for conservative management.

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 involves a physical examination to assess pain, swelling, and range of motion, followed by imaging studies. X-rays are typically used to confirm the fracture, evaluate the angle of the fracture line, and verify that the bone fragments are not displaced. Additional imaging, such as a CT scan, may be ordered if more detailed visualization is needed.

Treatment Options

Treatment for a nondisplaced oblique fracture of the left radius often includes immobilization with a cast or splint to keep the bone stable during healing. Pain management with over-the-counter or prescription medications may be recommended. Physical therapy is typically initiated after the initial healing phase to restore strength and mobility. Surgical intervention is rarely required unless the fracture becomes displaced or fails to heal properly.

Prognosis and Follow-Up

The prognosis for a nondisplaced oblique fracture of the left radius is generally favorable, with most fractures healing within 6–8 weeks. Follow-up appointments are necessary to monitor healing progress, usually with repeat X-rays. Full recovery of function is common, though some patients may experience residual stiffness or weakness. Adherence to immobilization and rehabilitation guidelines is key to optimizing outcomes.

Complications

While uncommon, potential complications include malunion (improper healing), nonunion (failure to heal), or nerve injury. Infection is not a concern for closed fractures but may occur if the fracture becomes open. Chronic pain or reduced range of motion may persist in some cases.

Lifestyle & Prevention

To reduce the risk of fractures, maintain bone health through a diet rich in calcium and vitamin D, and engage in weight-bearing exercise. Use protective gear during high-risk activities, such as sports or work involving heavy machinery. Avoid falls by removing tripping hazards at home and using assistive devices if balance is impaired.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, visible deformity, or inability to move the arm after an injury. Numbness, tingling, or coldness in the hand or fingers may indicate nerve or vascular involvement and require urgent evaluation.

Tips for Medical Coders

When coding S52.335A, ensure the documentation specifies a nondisplaced oblique fracture of the left radius shaft, an initial encounter, and a closed fracture. Verify that the laterality (left) and fracture type (oblique, nondisplaced) are clearly documented. For subsequent encounters or open fractures, different codes apply, so accuracy in documentation is critical.
