S52.245 Nondisplaced spiral fracture of shaft of ulna, left arm

Name of the Condition

• Nondisplaced spiral fracture of shaft of ulna, left arm

Summary

A nondisplaced spiral fracture of the shaft of the ulna, left arm, is a break in the long, straight portion of the ulna bone (one of the two forearm bones) with a spiral pattern and no misalignment of bone fragments. This fracture typically results from rotational forces and involves the main body of the ulna without displacement, where the broken bone ends remain in their normal anatomical position. The fracture affects the left arm and requires documentation of nondisplacement for accurate coding.

Causes

Direct trauma to the forearm, such as from a fall, blow, or accident. High-impact injuries, including sports-related incidents or motor vehicle collisions. Indirect forces transmitted through the wrist or elbow, potentially causing a twisting break in the ulna shaft.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or other conditions that weaken bone density.
• Previous fractures or bone abnormalities that may predispose to injury.
• Advanced age, which can reduce bone strength.

Symptoms

• Pain and tenderness localized to the forearm.
• Swelling and bruising around the injured area.
• Difficulty moving the arm, wrist, or hand due to pain or instability.
• Possible visible deformity if the fracture is displaced (though nondisplaced fractures may not show obvious deformity).

Diagnosis

Physical examination to assess tenderness, swelling, and range of motion. Imaging tests, such as X-rays, to confirm the fracture pattern and verify nondisplacement. Clinical evaluation to rule out associated injuries to surrounding tissues.

Treatment Options

Immobilization with a cast or splint to stabilize the fracture and promote healing. Pain management with over-the-counter or prescription medications. Physical therapy to restore strength and mobility once healing progresses. Close monitoring to ensure the fracture remains nondisplaced during recovery.

Prognosis and Follow-Up

Most nondisplaced spiral fractures of the ulna shaft heal well with proper immobilization and follow-up care. Recovery time typically ranges from 6 to 12 weeks, depending on the individual's health and adherence to treatment. Regular follow-up appointments with imaging may be needed to confirm healing and assess for complications.

Complications

Delayed healing or nonunion if the fracture does not stabilize properly. Malunion, though less likely with nondisplaced fractures, if misalignment occurs during healing. Nerve or vascular injury in severe cases, though rare with this fracture type. Chronic pain or stiffness in the forearm if mobility is not restored.

Lifestyle & Prevention

Avoid high-risk activities that increase the chance of falls or direct trauma to the forearm. Use protective gear during sports or physical activities. Maintain bone health through a balanced diet rich in calcium and vitamin D. Engage in regular weight-bearing exercise to support bone density.

When to Seek Professional Help

Severe or worsening pain that does not improve with rest or medication. Increased swelling, bruising, or visible deformity. Numbness, tingling, or loss of circulation in the hand or fingers. Inability to move the wrist or fingers, indicating potential nerve or tendon involvement.

Tips for Medical Coders

Document the fracture as nondisplaced and specify the left arm to align with the code S52.245. Include details about the spiral pattern and shaft location to support accurate coding. Ensure clinical documentation confirms the absence of displacement and the affected side (left) for proper code assignment.
