S92.351S Displaced fracture of fifth metatarsal bone, right foot, sequela

Name of the Condition

• Technical Term: Displaced fracture of fifth metatarsal bone, right foot, sequela
• Common Name: Healed displaced fracture of fifth metatarsal (right foot, with residual effects)

Summary

A displaced fracture of the fifth metatarsal bone in the right foot, sequela, refers to the residual effects or complications that persist after the initial fracture has healed. This condition occurs when the bone fragments, previously out of alignment, have healed in a non-anatomic position, potentially leading to long-term functional or structural changes. Sequela may include chronic pain, altered gait, or reduced mobility, depending on the extent of displacement and healing.

Causes

The underlying cause is a prior displaced fracture of the fifth metatarsal bone in the right foot. The sequela develops as a result of the initial injury and its healing process, where the bone fragments did not fully realign or healed in a position that affects foot mechanics.

Risk Factors

• Inadequate initial treatment or immobilization of the original fracture
• High-impact activities or weight-bearing stress on the affected foot during healing
• Pre-existing conditions that impair bone healing (e.g., poor circulation, diabetes)
• Advanced age, which may slow recovery and increase the risk of malunion

Symptoms

• Chronic pain or discomfort on the outer edge of the right foot
• Persistent swelling or stiffness in the affected area
• Difficulty with weight-bearing or altered gait
• Possible visible deformity or prominence at the fracture site
• Reduced range of motion in the foot or ankle

Diagnosis

A healthcare provider will evaluate the patient’s history of the original fracture and assess current symptoms. Physical examination focuses on pain, swelling, and functional limitations. Imaging, such as X-rays or CT scans, may be used to visualize the healed fracture and identify residual displacement or malunion. The diagnosis is confirmed by correlating clinical findings with evidence of prior fracture healing.

Treatment Options

Treatment depends on the severity of symptoms and functional impact. Conservative measures include pain management, physical therapy to improve strength and mobility, and orthotic devices or footwear modifications to reduce stress. Surgical intervention may be considered for significant deformity or persistent pain, involving realignment or reconstruction of the bone.

Prognosis and Follow-Up

Prognosis varies based on the extent of residual displacement and individual factors. Many patients experience improvement with conservative care, though some may have long-term limitations. Regular follow-up with a healthcare provider is important to monitor symptoms, adjust treatment, and address any new complications. Functional outcomes often depend on adherence to rehabilitation and activity modifications.

Complications

• Chronic pain or arthritis in the affected joint
• Persistent gait abnormalities or difficulty with mobility
• Increased risk of re-injury due to altered foot mechanics
• Nerve compression or irritation from malaligned bone
• Psychological impact from chronic discomfort or functional limitations

Lifestyle & Prevention

• Wear supportive footwear to reduce stress on the foot
• Avoid high-impact activities that strain the affected area
• Engage in low-impact exercises (e.g., swimming, cycling) to maintain fitness
• Follow a physical therapy program to strengthen surrounding muscles
• Maintain a healthy weight to minimize load on the foot

When to Seek Professional Help

Seek medical attention if you experience worsening pain, new swelling, or difficulty bearing weight. Consult a healthcare provider if symptoms interfere with daily activities or if you notice changes in the appearance of the foot. Prompt evaluation is important to address complications or adjust treatment as needed.

Tips for Medical Coders

This code (S92.351S) is used for the sequela of a displaced fracture of the fifth metatarsal bone in the right foot. Document the residual effects, such as chronic pain, deformity, or functional limitations, and confirm the prior fracture history. Ensure the sequela is directly attributable to the original injury and not a new condition. Code only when the sequela is the focus of treatment or evaluation.
