S92.323S Displaced fracture of second metatarsal bone, unspecified foot, sequela

Name of the Condition

• Technical Term: Displaced fracture of second metatarsal bone, unspecified foot, sequela
• ICD-10 Code: S92.323S
• Common Name: Broken second metatarsal (unspecified foot), sequela

Summary

A displaced fracture of the second metatarsal bone in an unspecified foot, sequela, refers to a residual condition resulting from a previous fracture. This occurs when the bone fragments remain misaligned after the initial injury has healed, potentially leading to chronic pain, altered gait, or functional limitations. The sequela designation indicates the condition is a long-term consequence of the original fracture, rather than an active acute injury.

Causes

The sequela arises from a prior displaced fracture of the second metatarsal bone, which may have been caused by trauma such as a fall, sports injury, or direct impact. Incomplete healing, malunion, or persistent displacement of the bone fragments during the recovery phase can result in this residual condition. The original fracture’s severity, treatment adherence, and individual healing capacity influence the development of sequela.

Risk Factors

• History of a displaced second metatarsal fracture
• Inadequate immobilization or rehabilitation after the initial injury
• Underlying conditions affecting bone healing (e.g., diabetes, poor circulation)
• Advanced age, which may impair bone repair and recovery
• High-impact activities resuming too soon after the original fracture

Symptoms

• Chronic pain in the midfoot, particularly during weight-bearing
• Swelling or tenderness at the fracture site
• Difficulty walking or altered gait pattern
• Stiffness or reduced range of motion in the foot
• Visible deformity or prominence of the affected bone

Diagnosis

Diagnosis involves a clinical evaluation of the patient’s history, including the original fracture and subsequent recovery. Physical examination assesses pain, swelling, and functional limitations. Imaging studies, such as X-rays, are used to confirm residual displacement, malunion, or signs of chronic changes in the bone. The sequela designation is confirmed by linking the current condition to the prior fracture.

Treatment Options

Treatment focuses on managing symptoms and improving function. Conservative measures include pain relief, physical therapy to strengthen surrounding muscles, and orthotic devices to support the foot. Surgical intervention may be considered for severe malunion or persistent functional impairment, such as osteotomy or bone grafting. Rehabilitation emphasizes gradual return to activity to prevent further injury.

Prognosis and Follow-Up

Prognosis varies based on the extent of residual displacement and individual factors. Many patients experience improved symptoms with conservative management, though some may have persistent limitations. Regular follow-up with a healthcare provider is recommended to monitor for complications, adjust treatment, and assess functional recovery. Long-term outcomes depend on adherence to rehabilitation and addressing any underlying conditions.

Complications

• Chronic pain or discomfort
• Arthritis in the affected joint due to altered mechanics
• Persistent gait abnormalities or difficulty with weight-bearing
• Increased risk of future fractures in the same area
• Nerve or soft tissue irritation from malaligned bone

Lifestyle & Prevention

• Wear supportive footwear to reduce stress on the foot
• Engage in low-impact exercises to maintain strength and flexibility
• Avoid high-impact activities that may exacerbate symptoms
• Maintain a healthy weight to minimize foot stress
• Follow post-fracture rehabilitation guidelines to optimize healing

When to Seek Professional Help

Seek medical attention if chronic pain worsens, swelling increases, or functional limitations progress. Prompt evaluation is necessary if new symptoms like numbness, tingling, or signs of infection (e.g., redness, warmth) develop. A healthcare provider can assess for complications and recommend appropriate interventions.

Tips for Medical Coders

Use S92.323S to document a displaced fracture of the second metatarsal bone, unspecified foot, as a sequela of a prior fracture. Ensure the medical record clearly links the current condition to the original injury and confirms the sequela status. Document any residual symptoms, functional limitations, or treatment approaches to support the code assignment. Avoid using this code for acute fractures or initial encounters.
