S72.472D Torus fracture of lower end of left femur, subsequent encounter for fracture with routine healing

Name of the Condition

• Torus fracture of lower end of left femur, subsequent encounter for fracture with routine healing

Summary

This condition involves a torus (buckle) fracture at the distal (lower) end of the left femur, the thigh bone, near the knee joint. The fracture is classified as a subsequent encounter, indicating follow-up care after the initial injury, and shows routine healing. Torus fractures are incomplete breaks that result in a buckling of the bone cortex, typically occurring in children due to the flexibility of their bones. The fracture involves the metaphyseal region, the area between the growth plate and the shaft of the bone, and may affect the stability of the knee joint. Routine healing suggests the fracture is progressing as expected without complications.

Causes

Direct force or axial loading to the femur, such as a fall onto the knee or a blow to the thigh. Common in children due to their developing bone structure, which is more pliable and prone to buckling rather than complete fracture. The subsequent encounter phase indicates the initial trauma has already occurred, and the current focus is on monitoring healing.

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 immobilization or follow-up care.

Symptoms

• Localized pain and tenderness at the fracture site, typically mild during healing.
• Swelling or mild deformity around the knee, if present.
• Limited range of motion in the knee joint, improving with healing.
• Possible difficulty bearing weight on the affected leg, depending on fracture severity.

Diagnosis

Physical examination to assess pain, swelling, and limb alignment. Imaging studies, such as X-rays, to confirm the torus fracture pattern and evaluate healing progress. Clinical correlation with the mechanism of injury and prior treatment. Routine healing is confirmed by radiographic evidence of callus formation or fracture line consolidation.

Treatment Options

• Immobilization with a cast or brace to support the fracture during healing.
• Pain management with over-the-counter or prescription medications.
• Physical therapy to restore range of motion and strength.
• Follow-up imaging to monitor healing progress.
• Weight-bearing restrictions, if recommended by the provider.

Prognosis and Follow-Up

Prognosis is generally favorable for torus fractures with routine healing, as they typically heal without long-term complications. Follow-up care focuses on monitoring healing and functional recovery. Most patients regain full mobility and return to normal activities within weeks to months, depending on the severity of the fracture and adherence to treatment.

Complications

• Delayed healing or nonunion, though rare with routine healing.
• Malunion, where the bone heals in an abnormal position.
• Persistent pain or stiffness in the knee joint.
• Growth plate disturbances in children, affecting limb length or alignment.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective gear during sports or activities with fall risks.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Follow prescribed weight-bearing restrictions and rehabilitation guidelines.

When to Seek Professional Help

• Increasing pain, swelling, or deformity at the fracture site.
• Difficulty bearing weight on the affected leg.
• Signs of infection, such as redness, warmth, or drainage.
• Numbness, tingling, or changes in skin color distal to the fracture.

Tips for Medical Coders

Document the laterality (left femur), encounter type (subsequent), and healing status (routine healing) to accurately assign this code. Ensure clinical notes specify the fracture type (torus) and confirm routine healing through imaging or provider assessment. Avoid coding for complications or additional encounters unless documented.
