S72.472S Torus fracture of lower end of left femur, sequela

Name of the Condition

• Torus fracture of lower end of left femur, sequela

Summary

This condition represents a torus (buckle) fracture of the distal (lower) end of the left femur, the thigh bone, near the knee joint, with residual effects or complications following the healing phase. A torus fracture is an incomplete break where the bone cortex buckles rather than fully fractures. The sequela designation indicates ongoing consequences from the prior injury, such as persistent pain, functional limitations, or structural changes. Torus fractures are common in children due to the flexibility of their bones and typically result from low-energy trauma.

Causes

The initial injury causing the torus fracture was likely due to direct force or axial loading to the femur, such as a fall onto the knee or a blow to the thigh. The sequela phase reflects the residual effects of this prior trauma, which may include incomplete healing, chronic instability, or persistent symptoms despite the fracture having occurred.

Risk Factors

• Pediatric age group, particularly during periods of rapid growth.
• Participation in high-impact activities or sports.
• Prior history of bone injuries or developmental abnormalities.
• Inadequate initial treatment or delayed healing.

Symptoms

• Persistent localized pain or discomfort at the fracture site.
• Reduced range of motion in the knee joint.
• Mild swelling or deformity around the knee.
• Difficulty bearing weight on the affected leg.
• Possible instability or altered gait.

Diagnosis

Physical examination to assess pain, swelling, and limb alignment. Imaging studies, such as X-rays, to evaluate residual bone changes or healing status. Clinical correlation with the patient’s history of the prior fracture and current functional limitations.

Treatment Options

Conservative management, including activity modification, physical therapy to improve strength and mobility, and pain relief measures. In some cases, orthopedic intervention may be considered if residual instability or deformity affects function. Treatment focuses on addressing the sequela rather than the initial fracture.

Prognosis and Follow-Up

Prognosis depends on the severity of residual effects and adherence to rehabilitation. Most patients experience gradual improvement with appropriate care, though some may have long-term limitations. Regular follow-up with an orthopedic specialist is recommended to monitor healing and functional recovery.

Complications

• Chronic pain or discomfort.
• Persistent joint instability.
• Limited mobility or gait abnormalities.
• Risk of re-injury due to altered biomechanics.
• Potential need for further intervention if symptoms worsen.

Lifestyle & Prevention

• Avoid high-impact activities that stress the knee joint.
• Use protective gear during sports or activities with fall risks.
• Engage in targeted physical therapy to strengthen surrounding muscles.
• Maintain a healthy weight to reduce joint stress.

When to Seek Professional Help

Seek medical attention if symptoms worsen, new pain or swelling develops, or functional limitations interfere with daily activities. Prompt evaluation is important to address complications or adjust treatment as needed.

Tips for Medical Coders

Document the residual effects or complications of the prior torus fracture, including any functional limitations or structural changes. Ensure the sequela designation is supported by clinical evidence of ongoing consequences from the initial injury. Code S72.472S is appropriate when the condition represents a late effect of the fracture, not the acute injury or healing phase.
