S62.235 Other nondisplaced fracture of base of first metacarpal bone, left hand

Name of the Condition

• Other nondisplaced fracture of base of first metacarpal bone, left hand

Summary

This condition involves a fracture at the base of the first metacarpal bone in the left hand, where the bone fragments remain in their normal anatomical position without displacement. The fracture may be partial or complete and typically affects the area connecting the thumb to the wrist. The severity and treatment depend on the fracture pattern and associated injuries.

Causes

Typically caused by direct trauma, such as a fall onto an outstretched hand, a blow to the thumb or hand, or a crushing injury. High-impact activities or accidents may also lead to fractures in this area.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or weakened bone structure, especially in older adults.
• Previous hand or thumb injuries that may have compromised bone integrity.

Symptoms

• Pain, swelling, and tenderness at the base of the thumb or left hand.
• Bruising or discoloration around the injury site.
• Limited range of motion or difficulty moving the thumb.
• Visible deformity in severe cases.

Diagnosis

Physical examination to assess pain, swelling, and mobility. Imaging tests, such as X-rays, CT scans, or MRIs, to confirm the fracture and evaluate its extent, including any joint involvement or displacement.

Treatment Options

• Immobilization: Using a cast, splint, or brace to stabilize the area and promote healing.
• Pain management: Medications to reduce discomfort and inflammation.
• Physical therapy: Exercises to restore strength and range of motion once healing progresses.
• Surgical intervention: Rarely required for nondisplaced fractures, but may be considered if stability is compromised.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and rest. Full recovery typically occurs within 4–6 weeks, though stiffness or mild discomfort may persist temporarily. Follow-up appointments monitor healing and adjust treatment as needed.

Complications

• Delayed union or nonunion of the fracture.
• Chronic pain or stiffness in the thumb or wrist.
• Arthritis in the affected joint over time.
• Nerve or tendon damage in severe cases.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid repetitive stress on the hand and thumb.
• Practice fall prevention strategies, especially for older adults.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, visible deformity, inability to move the thumb, or signs of infection (e.g., redness, fever). Persistent pain or limited mobility after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the fracture as "nondisplaced" and specify the left hand. Include details on the fracture pattern (e.g., transverse, oblique) and any associated injuries to support coding accuracy. Ensure the diagnosis aligns with clinical findings and imaging results.
