S59.022G Salter-Harris Type II physeal fracture of lower end of ulna, left arm, subsequent encounter for fracture with delayed healing

Name of the Condition

• Salter-Harris Type II physeal fracture of lower end of ulna, left arm, subsequent encounter for fracture with delayed healing

Summary

This condition involves a Salter-Harris Type II fracture of the growth plate (physeal) at the lower end of the ulna in the left arm, with delayed healing. It is a subsequent encounter, indicating ongoing care for a fracture that has not healed as expected. The injury typically affects children and adolescents, where the fracture extends through the physis (growth plate) and into the metaphysis. Trauma to the forearm, such as a fall onto an outstretched hand, is a common cause.

Causes

Salter-Harris Type II physeal fractures often result from direct impact or forceful twisting of the forearm. These injuries are common in activities involving sudden stops or collisions, where the growth plate is weaker than surrounding bone. Delayed healing may occur due to factors like inadequate immobilization, poor blood supply, or underlying health conditions affecting bone repair.

Risk Factors

• Children and adolescents are at higher risk due to the presence of growth plates.
• Participation in contact sports or activities with a high likelihood of falls increases risk.
• Certain genetic or metabolic conditions affecting bone development may also elevate susceptibility.
• Inadequate initial treatment or non-compliance with immobilization can contribute to delayed healing.

Symptoms

• Persistent pain and swelling near the wrist or forearm.
• Difficulty moving the wrist or hand, even with immobilization.
• Tenderness to touch at the fracture site.
• Possible bruising around the affected area.
• Signs of delayed healing, such as lack of progress on follow-up imaging.

Diagnosis

Physical examination by a healthcare professional to assess pain, swelling, and range of motion. Imaging tests, especially X-rays, are used to evaluate fracture alignment and healing progress. Additional studies like MRI or CT may be ordered if delayed healing is suspected to assess bone viability and soft tissue involvement.

Treatment Options

Treatment focuses on promoting healing and may include extended immobilization with a cast or splint. Surgical intervention, such as internal fixation, may be necessary if the fracture is unstable or fails to heal with conservative measures. Physical therapy is often recommended to restore function once healing is confirmed.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture and adherence to treatment. Most cases heal with proper care, but delayed healing may prolong recovery. Regular follow-up appointments with imaging are essential to monitor progress. Long-term outcomes are generally good, though some patients may experience minor functional limitations.

Complications

• Nonunion or malunion of the fracture.
• Growth disturbances due to damage to the growth plate.
• Chronic pain or stiffness in the wrist or forearm.
• Nerve or vascular injury in severe cases.

Lifestyle & Prevention

• Use protective gear during sports or high-risk activities.
• Ensure proper immobilization and follow-up care after an injury.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Avoid activities that strain the injured arm until fully healed.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, swelling, or inability to move the wrist or hand. Contact a healthcare provider if symptoms worsen or do not improve with treatment, or if there are signs of infection (e.g., redness, fever).

Tips for Medical Coders

Document the laterality (left arm), fracture type (Salter-Harris II), and the presence of delayed healing to support the code. Include details about the encounter type (subsequent) and any imaging or clinical findings that confirm delayed healing. Ensure documentation aligns with the specific code's requirements for accuracy.
