S62.232S Other displaced fracture of base of first metacarpal bone, left hand, sequela

Name of the Condition

• Other displaced fracture of base of first metacarpal bone, left hand, sequela

Summary

This condition represents a displaced fracture at the base of the first metacarpal bone (connecting the thumb to the wrist) in the left hand, classified as a sequela. A sequela indicates the condition is a late effect or residual of a previous injury. The fracture remains displaced, potentially affecting joint stability, function, or healing. Management focuses on addressing long-term consequences, such as chronic pain, stiffness, or deformity.

Causes

The fracture results from prior trauma, such as a fall onto an outstretched hand, a forceful blow to the thumb, or a crushing injury. The sequela classification implies the initial injury has healed, but residual effects persist. Displacement may have been incomplete or poorly aligned during healing, leading to ongoing issues.

Risk Factors

• Prior history of hand or thumb trauma, especially fractures or dislocations.
• Inadequate initial treatment or nonunion of the original fracture.
• Underlying conditions affecting bone healing, such as diabetes or vascular disease.
• Advanced age or osteoporosis, which may impair bone repair.

Symptoms

• Chronic pain, swelling, or tenderness at the base of the thumb or left hand.
• Reduced range of motion or stiffness in the thumb or wrist.
• Visible deformity or malalignment of the first metacarpal.
• Functional limitations, such as difficulty gripping or pinching.

Diagnosis

Physical examination to assess residual pain, swelling, and mobility. Imaging tests, such as X-rays or CT scans, to evaluate bone alignment, healing status, and joint involvement. Clinical correlation with the patient’s history of the initial injury is essential.

Treatment Options

• Conservative management: Splinting, physical therapy, or activity modification to improve function.
• Surgical intervention: Osteotomy (bone realignment) or arthrodesis (joint fusion) for severe deformity or instability.
• Pain management: NSAIDs, corticosteroid injections, or other modalities to address chronic discomfort.

Prognosis and Follow-Up

Prognosis depends on the extent of residual displacement, joint damage, and patient compliance with therapy. Most patients experience improved function with treatment, but some may have persistent limitations. Regular follow-up with imaging and functional assessments is recommended to monitor healing and adjust care.

Complications

• Chronic pain or arthritis in the thumb or wrist joint.
• Persistent deformity or instability affecting hand function.
• Nerve or tendon irritation from malaligned bone fragments.
• Reduced grip strength or dexterity.

Lifestyle & Prevention

• Avoid repetitive or high-impact activities that stress the thumb or wrist.
• Use protective gear during sports or manual labor.
• Maintain bone health with calcium, vitamin D, and weight-bearing exercise.
• Follow post-injury rehabilitation protocols to optimize healing.

When to Seek Professional Help

Seek care if symptoms worsen, new deformity develops, or functional limitations interfere with daily activities. Prompt evaluation is needed for sudden pain, swelling, or loss of motion, which may indicate a new injury or complication.

Tips for Medical Coders

Document the sequela nature of the fracture, including the original injury date and any prior treatments. Specify the left-hand involvement and displaced status. Ensure clinical correlation with imaging or physical exam findings to support the sequela classification.
