S55.01 Laceration of ulnar artery at forearm level

Name of the Condition

• Laceration of ulnar artery at forearm level

Summary

A laceration of the ulnar artery at the forearm level refers to a cut or tear in the ulnar artery within the forearm region. This type of injury can disrupt blood flow to the hand and fingers, depending on the severity of the arterial damage. The condition may result from trauma and can involve associated tissue injury, such as damage to surrounding nerves or muscles.

Causes

Direct trauma to the forearm, including lacerations from sharp objects, blunt force injuries, or penetrating wounds. Fractures of the forearm bones (radius or ulna) may also damage the ulnar artery. Iatrogenic injuries during surgical procedures or medical interventions in the forearm area.

Risk Factors

• Participation in activities with a high risk of forearm trauma (e.g., contact sports, manual labor).
• Use of sharp tools or machinery without proper safety precautions.
• Preexisting vascular conditions that may weaken arterial walls.
• Proximity to the ulnar artery during surgical or interventional procedures.

Symptoms

• Visible bleeding or hematoma at the injury site.
• Pain, swelling, or tenderness in the forearm.
• Weak or absent pulse in the wrist or hand (if arterial flow is compromised).
• Numbness, tingling, or coldness in the fingers (due to reduced blood flow).
• Pale or bluish discoloration of the hand or fingers.

Diagnosis

Physical examination to assess pulses, skin temperature, and sensory function. Doppler ultrasound or angiography to evaluate vascular integrity and blood flow. Imaging studies (e.g., X-rays) may be used to identify associated fractures or soft tissue damage.

Treatment Options

• Direct pressure to control bleeding.
• Surgical repair or ligation of the artery, depending on the extent of damage.
• Revascularization procedures to restore blood flow if ischemia is present.
• Pain management and wound care to prevent infection.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and timely intervention. Early treatment can minimize complications such as tissue loss or nerve damage. Follow-up may include monitoring for signs of infection, assessing circulation, and physical therapy to restore function.

Complications

• Ischemia or tissue loss due to reduced blood flow.
• Nerve damage leading to numbness or weakness.
• Infection at the injury site.
• Chronic pain or functional impairment.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Follow safety protocols when handling sharp tools or machinery.
• Maintain awareness of forearm anatomy to avoid accidental injury.
• Seek prompt medical care for any trauma to the forearm.

When to Seek Professional Help

Seek immediate medical attention if there is severe bleeding, loss of pulse in the hand, or signs of ischemia (e.g., pale or blue fingers). Persistent pain, swelling, or numbness after an injury also warrants evaluation.

Tips for Medical Coders

Document the specific location (forearm level) and nature of the injury (laceration) to support accurate coding. Include details about associated injuries or interventions, as these may impact code assignment. Ensure documentation aligns with clinical findings and procedural notes.
