S62.253S Displaced fracture of neck of first metacarpal bone, unspecified hand, sequela

Name of the Condition

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

Summary

This condition represents a displaced fracture of the neck of the first metacarpal bone (the bone connecting the thumb to the wrist) with residual effects following the acute phase of injury. Sequela indicates the presence of chronic complications or long-term consequences resulting from the initial fracture, such as persistent pain, deformity, or functional impairment.

Causes

The sequela arises from a prior displaced fracture of the first metacarpal neck, typically caused by direct trauma like a fall onto an outstretched hand, a forceful blow to the thumb, or a crushing injury. The initial injury may have involved displacement of bone fragments, leading to ongoing issues after healing.

Risk Factors

• Prior history of hand or thumb trauma, including fractures or severe sprains.
• Inadequate initial treatment or delayed healing of the original fracture.
• Underlying conditions affecting bone healing, such as diabetes or poor circulation.
• Activities or occupations requiring repetitive hand use, which may exacerbate residual symptoms.

Symptoms

• Chronic pain, stiffness, or tenderness at the base of the thumb or hand.
• Reduced range of motion or difficulty gripping objects.
• Visible or palpable deformity of the metacarpal bone.
• Weakness in the thumb or hand, affecting daily activities.
• Occasional swelling or discomfort with use.

Diagnosis

Evaluation includes a detailed patient history to confirm prior fracture and assess symptom duration. Physical examination assesses residual deformity, range of motion, and functional limitations. Imaging, such as X-rays or CT scans, may be used to evaluate bone alignment and identify any persistent issues like malunion or arthritis.

Treatment Options

• Conservative management: Physical therapy to improve strength and mobility, pain management, and activity modification.
• Assistive devices: Splints or braces to support the thumb during daily tasks.
• Surgical intervention: Rarely, corrective surgery may be considered for severe deformity or functional impairment.
• Rehabilitation: Long-term therapy to restore function and minimize discomfort.

Prognosis and Follow-Up

Prognosis depends on the severity of the initial injury and residual effects. Most patients experience improved function with conservative treatment, though some may have persistent limitations. Regular follow-up with a healthcare provider is recommended to monitor symptoms and adjust management as needed.

Complications

• Chronic pain or stiffness in the thumb or hand.
• Arthritis or joint degeneration due to altered mechanics.
• Reduced grip strength or dexterity.
• Psychological impact from ongoing functional limitations.

Lifestyle & Prevention

• Avoid repetitive or high-impact activities that stress the thumb or hand.
• Use ergonomic tools or adaptive devices to reduce strain.
• Maintain overall bone health through a balanced diet and regular exercise.
• Protect the hand during activities with potential for injury (e.g., sports, manual labor).

When to Seek Professional Help

Seek care if symptoms worsen, new pain or deformity develops, or functional limitations interfere with daily activities. Prompt evaluation is important if signs of infection (e.g., redness, swelling, fever) or nerve involvement (e.g., numbness, tingling) occur.

Tips for Medical Coders

This code is used for sequela of a displaced fracture of the first metacarpal neck. Document the relationship between the current condition and the prior fracture, including the time elapsed since the initial injury. Ensure the diagnosis supports the use of a sequela code, as it applies to complications or residual effects following the acute phase.
