S62.252S Displaced fracture of neck of first metacarpal bone, left hand, sequela

Name of the Condition

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

Summary

This condition represents a displaced fracture of the neck of the first metacarpal bone (connecting the thumb to the wrist) in the left hand, classified as a sequela. A sequela indicates a residual effect or complication following the acute phase of the injury. The fracture fragments remain misaligned, and the condition reflects long-term consequences of the initial trauma, such as persistent pain, functional impairment, or structural changes.

Causes

The sequela arises from a prior displaced fracture of the neck of the first metacarpal bone. The original injury was likely caused by direct trauma, such as a fall onto an outstretched hand, a forceful blow to the thumb, or a crushing injury. Inadequate healing, malunion, or nonunion of the initial fracture may contribute to the development of residual symptoms or structural abnormalities.

Risk Factors

• Inadequate initial treatment or noncompliance with rehabilitation protocols.
• High-impact activities or occupations that stress the hand and thumb.
• Underlying conditions affecting bone healing, such as diabetes or vascular disease.
• Advanced age, which may impair bone repair and recovery.

Symptoms

• Chronic pain, swelling, or tenderness at the base of the thumb or hand.
• Reduced range of motion or stiffness in the thumb or wrist.
• Visible deformity or malalignment of the metacarpal bone.
• Functional limitations, such as difficulty gripping or performing fine motor tasks.
• Possible nerve compression or associated joint instability.

Diagnosis

Physical examination to assess residual pain, swelling, and functional impairment. Imaging tests, such as X-rays, CT scans, or MRIs, to evaluate the alignment of the fracture, assess for malunion or nonunion, and identify any associated joint damage or degenerative changes. Clinical correlation with the patient’s history of the initial injury is essential.

Treatment Options

• Conservative management: Physical therapy to improve range of motion, strength, and function. Pain management strategies, including medications or modalities like heat/cold therapy.
• Orthotic devices: Splints or braces to stabilize the thumb and support healing.
• Surgical intervention: Considered for severe malalignment, persistent pain, or functional impairment. Procedures may include osteotomy (realignment of the bone) or joint reconstruction.
• Rehabilitation: Long-term therapy to restore mobility and optimize hand function.

Prognosis and Follow-Up

Prognosis depends on the severity of the residual displacement, joint involvement, and response to treatment. Most patients experience improved function with appropriate management, though some may have persistent limitations. Regular follow-up is recommended to monitor healing, assess functional recovery, and address any new symptoms or complications.

Complications

• Chronic pain or arthritis in the thumb or wrist joint.
• Persistent deformity or instability of the metacarpal bone.
• Nerve or tendon damage affecting hand function.
• Reduced grip strength or dexterity.

Lifestyle & Prevention

• Avoid activities that stress the injured hand until fully healed and cleared by a healthcare provider.
• Use protective gear during high-risk activities (e.g., sports) to prevent re-injury.
• Maintain bone health through a balanced diet and regular exercise to support overall skeletal strength.
• Follow post-treatment rehabilitation plans to optimize recovery and minimize long-term effects.

When to Seek Professional Help

Seek medical attention if you experience worsening pain, new swelling, or loss of function in the hand or thumb. Consult a healthcare provider if you notice signs of infection (e.g., redness, warmth, or drainage) or if symptoms do not improve with conservative management.

Tips for Medical Coders

This code (S62.252S) is used for a displaced fracture of the neck of the first metacarpal bone in the left hand, classified as a sequela. Documentation should clearly indicate the residual effects of a prior fracture, including details on alignment, functional impairment, and any ongoing treatment. Ensure the sequela is linked to the original injury and that the left-hand specification is accurately recorded.
