S62.243S Displaced fracture of shaft of first metacarpal bone, unspecified hand, sequela

Name of the Condition

• Displaced fracture of shaft of first metacarpal bone, unspecified hand, sequela

Summary

This condition represents a displaced fracture of the shaft (midportion) of the first metacarpal bone, which connects the thumb to the wrist, with displacement of the bone fragments. The term "sequela" indicates this is a residual effect or complication following the initial injury. Displacement means the broken pieces are no longer aligned properly. The severity and management depend on the extent of displacement and any long-term functional or structural changes.

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. Sequela arise as a result of the initial fracture and its healing process.

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.
• Inadequate initial treatment or healing complications from the original fracture.

Symptoms

• Chronic pain, swelling, or tenderness in the thumb or base of the hand.
• Reduced range of motion or difficulty moving the thumb.
• Visible deformity or malalignment in severe cases.
• Functional limitations, such as difficulty gripping or performing fine motor tasks.

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 residual displacement, alignment, and any associated complications like arthritis or malunion.

Treatment Options

• Rehabilitation: Physical therapy to improve strength, range of motion, and function.
• Orthotics or splinting: To support the hand and thumb during healing or to manage residual instability.
• Surgical intervention: In cases of significant malunion or functional impairment, corrective surgery may be considered.
• Pain management: Medications or other therapies to address chronic discomfort.

Prognosis and Follow-Up

Prognosis depends on the extent of initial injury, displacement, and healing. Most patients experience improved function with rehabilitation, though some may have permanent limitations. Regular follow-up with a healthcare provider is important to monitor for complications and adjust treatment as needed.

Complications

• Chronic pain or stiffness.
• Arthritis or joint degeneration.
• Malunion (improper healing) or nonunion (failure to heal).
• Reduced grip strength or dexterity.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through proper nutrition and exercise.
• Follow post-injury rehabilitation plans to optimize recovery.
• Avoid re-injury by modifying activities that stress the hand or thumb.

When to Seek Professional Help

Seek medical attention if you experience worsening pain, swelling, or loss of function, or if you notice new deformity or numbness in the hand or thumb.

Tips for Medical Coders

This code is used for a displaced fracture of the first metacarpal shaft, unspecified hand, with sequela. Document the residual effects of the initial injury, including functional limitations or structural changes. Ensure the diagnosis supports the use of the sequela code and that the encounter is for managing the long-term effects, not the acute phase.
