S72.456 Nondisplaced supracondylar fracture without intracondylar extension of lower end of unspecified femur

Name of the Condition

• Nondisplaced supracondylar fracture without intracondylar extension of lower end of unspecified femur

Summary

This condition involves a fracture at the distal (lower) end of the 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). This type of fracture may affect knee stability and function depending on the severity of the injury.

Causes

High-impact trauma, such as falls, motor vehicle accidents, or direct blows to the thigh. Sports injuries or physical altercations. Stress fractures from repetitive overuse or strenuous activity.

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 region.
• Swelling, bruising, or visible deformity of the affected leg.
• Inability to bear weight or move the leg normally.
• 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 and rule out intracondylar extension or displacement.

Treatment Options

• Immobilization with a cast or brace to allow healing.
• Pain management with medications or ice.
• Physical therapy to restore strength and mobility after healing.
• Surgical intervention if displacement occurs or if the fracture is unstable.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment, but recovery time varies. Follow-up imaging may be needed to monitor healing. Long-term outcomes depend on the extent of the injury and adherence to rehabilitation.

Complications

• Delayed healing or nonunion.
• Post-traumatic arthritis in the knee joint.
• Nerve or blood vessel damage.
• Chronic pain or stiffness.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health with calcium and vitamin D.
• Avoid falls by improving home safety (e.g., removing tripping hazards).
• Engage in weight-bearing exercises to strengthen bones.

When to Seek Professional Help

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

Tips for Medical Coders

Document the fracture location (supracondylar, nondisplaced, no intracondylar extension) and specify the femur as "unspecified" if the side is not documented. Ensure trauma details and clinical findings support the code assignment.
