S52.222 Displaced transverse fracture of shaft of left ulna

Name of the Condition

• Displaced transverse fracture of shaft of left ulna

Summary

A displaced transverse fracture of the shaft of the left ulna is a break across the long, central portion of the ulna bone (one of the two forearm bones) where the bone fragments are shifted out of alignment. The fracture runs horizontally through the bone shaft, and the displacement indicates the bone pieces are not in their normal anatomical position.

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 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.

Diagnosis

Physical examination to assess tenderness, swelling, and range of motion. Imaging tests, such as X-rays, to confirm the fracture and evaluate alignment. Additional imaging (e.g., CT scans) may be used for complex cases.

Treatment Options

• Immobilization with a cast or splint to stabilize the fracture.
• Closed reduction to realign displaced bone fragments, if necessary.
• Surgical intervention (e.g., internal fixation) for unstable or severely displaced fractures.
• Pain management and physical therapy to restore function.

Prognosis and Follow-Up

Prognosis depends on fracture severity, treatment, and patient factors. Most fractures heal with proper immobilization or surgery, but recovery may take several weeks to months. Follow-up imaging and clinical evaluations monitor healing and alignment.

Complications

• Nonunion or delayed union of the fracture.
• Malunion, where the bone heals in an abnormal position.
• Nerve or blood vessel damage near the fracture site.
• Infection (if surgical intervention is required).

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports).
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by modifying home environments (e.g., removing tripping hazards).
• Engage in weight-bearing exercises to strengthen bones.

When to Seek Professional Help

Seek immediate medical attention for severe pain, visible deformity, inability to move the arm, or signs of nerve/vascular compromise (e.g., numbness, coldness). Follow up with a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the fracture location (left ulna), displacement status, and any associated injuries. Ensure clinical documentation specifies the fracture type (transverse) and displacement to support accurate coding. Include details about the encounter (e.g., initial, subsequent) and fracture status (open/closed) if applicable.
