S72.454C Nondisplaced supracondylar fracture without intracondylar extension of lower end of right femur, initial encounter for open fracture type IIIA, IIIB, or IIIC

Name of the Condition

• Nondisplaced supracondylar fracture without intracondylar extension of lower end of right femur, initial encounter for open fracture type IIIA, IIIB, or IIIC

Summary

This condition involves a fracture at the distal (lower) end of the right femur, specifically in the supracondylar region (above the condyles). The fracture does not extend into the intracondylar area (the space between the condyles), and the bone fragments remain in their normal alignment (nondisplaced). The fracture is classified as open (compound) with a type IIIA, IIIB, or IIIC designation, indicating varying degrees of soft tissue damage and contamination. This type of injury may affect knee stability and function depending on the severity of the trauma and associated soft tissue injury.

Causes

High-impact trauma, such as falls, motor vehicle accidents, or direct blows to the thigh. Sports injuries or physical altercations involving force to the knee or thigh. Open fractures may result from trauma that disrupts the skin and exposes the fracture site.

Risk Factors

• Advanced age, which may lead to decreased bone density.
• Osteoporosis or other bone-weakening conditions.
• Participation in high-risk activities or contact sports.
• Prior history of femur fractures or bone disorders.
• Conditions that impair wound healing or increase infection risk.

Symptoms

• Severe pain in the knee or thigh region.
• Swelling, bruising, or visible deformity of the affected leg.
• Inability to bear weight or move the leg normally.
• Open wound at the fracture site (for open fractures).
• Possible numbness or tingling if nerves are involved.
• Signs of infection (e.g., redness, drainage) in open fractures.

Diagnosis

Physical examination to assess pain, swelling, limb alignment, and wound characteristics. Imaging studies, such as X-rays or CT scans, to confirm the fracture and rule out intracondylar extension. Evaluation of soft tissue damage and wound contamination for open fractures. Assessment of neurovascular status to check for nerve or blood vessel involvement.

Treatment Options

Stabilization of the fracture, often with casting, bracing, or surgical fixation, depending on the severity of the injury and soft tissue damage. Wound care and antibiotics for open fractures to prevent infection. Pain management and physical therapy to restore function. Surgical intervention may be required for severe soft tissue injury or unstable fractures.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, soft tissue damage, and treatment response. Nondisplaced fractures generally have a favorable outcome with proper management. Follow-up appointments to monitor healing, assess functional recovery, and adjust treatment as needed. Long-term monitoring for complications such as infection, nonunion, or arthritis.

Complications

• Infection, particularly in open fractures.
• Nonunion or delayed healing of the fracture.
• Arthritis or joint stiffness due to trauma.
• Nerve or blood vessel damage.
• Chronic pain or functional impairment.

Lifestyle & Prevention

Avoid high-risk activities that increase fracture risk. Maintain bone health through proper nutrition (e.g., calcium, vitamin D) and exercise. Use protective equipment during sports or activities with fall risk. Prompt treatment of open wounds to reduce infection risk.

When to Seek Professional Help

Severe pain, swelling, or deformity after trauma. Open wound at the fracture site. Numbness, tingling, or loss of circulation in the affected limb. Signs of infection (e.g., fever, redness, drainage). Inability to bear weight or move the leg normally.

Tips for Medical Coders

Document the fracture location (right femur, supracondylar, nondisplaced, no intracondylar extension), the open fracture type (IIIA, IIIB, or IIIC), and the encounter type (initial). Specify the side (right) and confirm no intracondylar involvement. Ensure documentation supports the open fracture classification and initial encounter status.
