S65.091 Other specified injury of ulnar artery at wrist and hand level of right arm

Name of the Condition

• Other specified injury of ulnar artery at wrist and hand level of right arm

Summary

An other specified injury of the ulnar artery at the wrist and hand level of the right arm involves damage to the ulnar artery in this anatomical region, which may result from trauma or other mechanisms. This condition requires evaluation to assess the extent of vascular injury and determine appropriate management, as the ulnar artery is a critical blood vessel supplying the hand and fingers.

Causes

Direct trauma to the wrist or hand, such as lacerations, puncture wounds, or crush injuries. Penetrating injuries from sharp objects like glass, knives, or tools. Blunt force trauma causing vessel compression or disruption. Iatrogenic injury during surgical procedures involving the wrist or hand.

Risk Factors

• Participation in activities with a risk of hand or wrist trauma (e.g., sports, manual labor).
• Use of sharp objects or tools without proper safety precautions.
• Preexisting vascular conditions that may weaken vessel integrity.
• Advanced age, which may be associated with reduced tissue resilience.

Symptoms

• Visible bleeding or hematoma at the injury site.
• Pain, swelling, or tenderness in the wrist or hand.
• Weak or absent pulses in the affected digits.
• Coolness, pallor, or discoloration of the hand or fingers.
• Numbness or tingling in the ulnar nerve distribution (e.g., little finger, ring finger).

Diagnosis

Physical examination to assess for vascular compromise, including pulse palpation and capillary refill. Doppler ultrasound or angiography to evaluate arterial flow and identify injury extent. Imaging studies (e.g., X-ray, MRI) to rule out associated fractures or soft tissue damage.

Treatment Options

• Immediate wound care and hemostasis for bleeding injuries.
• Surgical repair or revascularization if arterial disruption is severe.
• Anticoagulation or antiplatelet therapy to prevent thrombosis.
• Pain management and monitoring for ischemic complications.
• Rehabilitation to restore function and prevent stiffness.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and timeliness of treatment. Minor injuries may resolve with conservative management, while severe disruptions may require surgical intervention. Follow-up includes monitoring for signs of ischemia, infection, or functional impairment. Long-term outcomes may involve residual pain, reduced mobility, or nerve dysfunction.

Complications

• Ischemia or tissue necrosis due to inadequate blood flow.
• Infection at the injury site.
• Nerve damage (e.g., ulnar nerve injury) leading to sensory or motor deficits.
• Chronic pain or stiffness in the wrist or hand.
• Vascular insufficiency requiring further intervention.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, manual labor).
• Avoid handling sharp objects without proper precautions.
• Maintain awareness of hand/wrist positioning to prevent accidental trauma.
• Seek prompt medical attention for injuries to minimize complications.

When to Seek Professional Help

• Persistent bleeding or swelling unresponsive to initial care.
• Signs of ischemia (coolness, pallor, numbness) in the hand or fingers.
• Severe pain or inability to move the wrist/hand.
• Suspected deep tissue or vascular injury.

Tips for Medical Coders

Document the specific nature of the injury (e.g., laceration, contusion) and its anatomical location. Include details about the mechanism of injury, clinical findings, and any interventions performed. Ensure the right arm specification is clearly noted to support accurate coding.
