S72.452A Displaced supracondylar fracture without intracondylar extension of lower end of left femur, initial encounter for closed fracture

Name of the Condition

• Displaced supracondylar fracture without intracondylar extension of lower end of left femur, initial encounter for closed fracture

Summary

This condition involves a displaced fracture at the distal (lower) end of the left femur, specifically in the supracondylar region (above the condyles), without extension into the intracondylar area. The fracture is closed, meaning the skin remains intact, and it is the initial encounter for this injury. Displacement indicates the bone fragments are misaligned, which may affect knee stability and function.

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. Stress fractures from repetitive overuse or strenuous activity are less common but possible.

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.

Symptoms

• Severe pain in the knee or thigh area.
• Swelling, bruising, or visible deformity around the knee.
• Inability to bear weight or move the knee joint properly.
• Possible numbness or tingling if nerves are involved.

Diagnosis

Physical examination to assess pain, swelling, and limb alignment. Imaging studies, such as X-rays or CT scans, to confirm the fracture type, displacement, and rule out intracondylar extension. Evaluation of skin integrity to confirm a closed fracture.

Treatment Options

• Immobilization with a cast or brace to stabilize the fracture.
• Pain management with medications.
• Surgical intervention (e.g., internal fixation) if displacement is severe or unstable.
• Physical therapy to restore mobility and strength after healing.

Prognosis and Follow-Up

Prognosis depends on fracture severity, treatment, and patient factors. Most heal with proper care, but residual stiffness or weakness may occur. Follow-up includes monitoring healing via imaging and assessing functional recovery. Long-term follow-up may be needed for persistent symptoms.

Complications

• Nonunion or malunion of the fracture.
• Post-traumatic arthritis in the knee.
• Nerve or vascular damage from the injury.
• Chronic pain or limited mobility.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health with calcium and vitamin D.
• Avoid falls by modifying home environments (e.g., removing tripping hazards).
• Gradually return to weight-bearing activities as directed.

When to Seek Professional Help

Seek immediate care for severe pain, visible deformity, inability to move the leg, or signs of infection (e.g., fever, increased swelling). Follow up with a healthcare provider if pain worsens or does not improve with treatment.

Tips for Medical Coders

Document the fracture location (left femur), displacement, absence of intracondylar extension, closed nature, and initial encounter status. Ensure clinical notes specify the fracture type and alignment to support coding accuracy.
