S72.131K Displaced apophyseal fracture of right femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Displaced apophyseal fracture of right femur, subsequent encounter for closed fracture with nonunion

Summary

A displaced apophyseal fracture of the right femur is a break in the apophysis (a bony growth area) of the femur, with the bone fragments separated from their normal anatomical position. This condition is classified as a subsequent encounter for a closed fracture with nonunion, indicating the fracture has not healed properly after prior treatment. The fracture remains closed (skin intact) but shows no signs of union, requiring ongoing management.

Causes

Apophyseal fractures commonly result from direct trauma, such as falls or high-impact injuries. Nonunion may occur due to inadequate immobilization, poor blood supply to the fracture site, or excessive movement during healing. Underlying conditions like osteoporosis or metabolic disorders can also impair bone healing.

Risk Factors

• Advanced age, particularly with osteoporosis or poor bone health.
• History of prior fractures or delayed healing.
• Conditions that affect bone metabolism, such as diabetes or smoking.
• Inadequate initial treatment or non-compliance with immobilization.

Symptoms

• Persistent hip or thigh pain, often localized to the fracture site.
• Inability to bear weight on the affected leg.
• Swelling or tenderness that does not improve over time.
• Possible deformity or instability in the hip/thigh region.

Diagnosis

Physical examination to assess pain, range of motion, and stability. Imaging studies, including X-rays or CT scans, to confirm nonunion and evaluate bone alignment. Additional tests, such as bone scans, may assess healing potential.

Treatment Options

• Surgical intervention, such as bone grafting or internal fixation, to promote union.
• Prolonged immobilization or bracing to stabilize the fracture.
• Physical therapy to restore strength and mobility once healing progresses.
• Medications to support bone health, such as bisphosphonates or supplements.

Prognosis and Follow-Up

Prognosis depends on the severity of nonunion and response to treatment. Regular follow-up with imaging is necessary to monitor healing. Most patients achieve union with appropriate intervention, but recovery may take several months. Long-term mobility and function are typically preserved with successful treatment.

Complications

• Chronic pain or instability if nonunion persists.
• Increased risk of future fractures due to weakened bone.
• Potential need for additional surgeries if initial treatment fails.
• Limited mobility or functional impairment during healing.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a diet rich in calcium and vitamin D to support bone health.
• Use protective gear during sports or activities with fall risks.
• Follow post-treatment guidelines strictly to optimize healing.

When to Seek Professional Help

Seek immediate care if pain worsens, swelling increases, or new deformity develops. Contact a provider if weight-bearing becomes impossible or if symptoms do not improve with rest and immobilization.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with nonunion. Include details on prior treatment, imaging findings confirming nonunion, and any surgical or therapeutic interventions. Ensure the fracture is specified as displaced and on the right femur, with clear notation of the nonunion status.
