S49.032S Salter-Harris Type III physeal fracture of upper end of humerus, left arm, sequela

Name of the Condition

• Salter-Harris Type III physeal fracture of upper end of humerus, left arm, sequela (ICD-10 Code: S49.032S)

Summary

This code describes a Salter-Harris Type III fracture involving the growth plate (physeal) at the upper end of the left humerus, with sequela indicating residual effects following the acute phase of the injury. This type of fracture extends through the growth plate and into the epiphysis (the end of the bone), typically occurring in children and adolescents due to the relative weakness of the physis during development. The "sequela" modifier denotes complications or conditions resulting from the fracture that persist after the active healing phase.

Causes

Trauma, such as a fall onto an outstretched hand or a direct blow to the shoulder, is the primary cause. These injuries often occur during sports, play, or accidents involving forceful arm movement. The sequela may arise from incomplete healing, malunion, or long-term effects of the initial injury.

Risk Factors

• Age (most common in children and adolescents with open growth plates)
• Participation in high-impact sports or activities
• Prior growth plate injuries
• Inadequate initial treatment or healing complications

Symptoms

• Chronic pain or discomfort at the shoulder or upper arm
• Limited range of motion or stiffness
• Visible deformity or limb length discrepancy
• Difficulty with daily activities involving arm use

Diagnosis

Diagnosis relies on a physical examination to assess residual pain, swelling, and range of motion, combined with imaging studies like X-rays to visualize any persistent fracture lines, malunion, or growth plate disturbances. A detailed patient history, including the original injury and treatment, is also important to confirm the sequela.

Treatment Options

• Rehabilitation: Physical therapy to improve strength, flexibility, and function.
• Orthopedic evaluation: For assessment of deformity or growth plate issues.
• Pain management: Medications or other interventions to address chronic discomfort.
• Surgical consultation: If significant deformity or functional impairment is present.

Prognosis and Follow-Up

Prognosis depends on the severity of the initial injury, treatment, and any resulting complications. Regular follow-up with an orthopedic specialist is recommended to monitor growth plate development and address long-term effects. Most patients experience improved function with appropriate management, though some may have persistent limitations.

Complications

• Growth plate disturbance leading to limb length discrepancy
• Chronic pain or arthritis
• Reduced range of motion or stiffness
• Aesthetic concerns due to deformity

Lifestyle & Prevention

• Avoid high-impact activities that risk re-injury.
• Use protective gear during sports or play.
• Follow prescribed rehabilitation protocols to optimize recovery.
• Maintain regular medical follow-up to monitor for complications.

When to Seek Professional Help

Seek medical attention if there is increasing pain, new swelling, reduced mobility, or signs of deformity. Prompt evaluation is important to address any worsening or new complications.

Tips for Medical Coders

This code is used for the sequela of a Salter-Harris Type III physeal fracture of the upper humerus, left arm. Document the residual effects clearly, including any functional limitations or anatomical changes. Ensure the sequela is directly related to the original fracture and not an unrelated condition.
