Name of the Condition

• Displaced fracture of proximal phalanx of left thumb, initial encounter for closed fracture

Summary

• This injury involves a fracture in the proximal phalanx, which is the bone segment closest to the hand, of the left thumb. The fracture is closed, meaning the skin has not been pierced by the bone. A 'displaced' fracture means the bone segments have shifted out of their normal alignment.

Causes

• Typically caused by direct trauma or impact to the thumb, such as falling onto an outstretched hand or blunt force trauma.

Risk Factors

• Participation in contact sports or activities with a high risk of falling, such as cycling or skateboarding.
• Osteoporosis or other conditions that weaken bones.
• Previous fractures or hand injuries.

Symptoms

• Pain, swelling, and bruising in the thumb.
• Limited range of motion or difficulty moving the thumb.
• Visible deformity or abnormal thumb alignment.

Diagnosis

• Physical examination and discussion of injury history.
• Imaging tests, such as X-rays, to determine fracture displacement and severity.

Treatment Options

• Immobilization using a splint or cast to keep the bone in place and allow healing.
• Closed reduction procedure performed by a healthcare professional to realign bones.
• Surgery may be necessary if the fracture is significantly displaced and cannot be corrected by other means.
• Pain management with medications and physiotherapy to restore function post-immobilization.

Prognosis and Follow-Up

• With proper treatment, most people recover full function.
• Regular follow-ups are essential to monitor bone healing and prevent complications.

Complications

• Improperly healed fractures leading to stiffness or reduced thumb function.
• Nonunion or delayed healing, where the bone does not heal properly.
• Potential for arthritis in the joint if the fracture affects the joint surface.

Lifestyle & Prevention

• Using protective gear during high-risk activities.
• Ensuring safe environments to minimize risk of falls or hand injuries.
• Exercises to strengthen hand and thumb muscles, especially if previously injured.

When to Seek Professional Help

• Immediate medical attention should be sought if severe pain, swelling, or visible deformity occurs after a thumb injury.
• If symptoms persist or worsen despite treatment, seek further medical evaluation.

Tips for Medical Coders

• Ensure accurate representation of the affected thumb (left vs. right) and document the encounter as initial.
• Verify that the fracture is documented as closed.
• Avoid confusing similar injuries; precision is crucial for proper coding and billing.
