S82.311A Torus fracture of lower end of right tibia, initial encounter for closed fracture

Name of the Condition

• Torus fracture of lower end of right tibia, initial encounter for closed fracture

Summary

This condition involves a torus fracture at the lower end of the right tibia, a type of incomplete fracture where the bone buckles but does not fully break. The injury is closed (skin intact) and occurs during the initial encounter. Torus fractures are common in children due to their softer, more pliable bones and typically result from axial loading or bending forces. The lower tibia is part of the ankle joint, so this injury may affect mobility and require specific management.

Causes

Torus fractures of the lower tibia typically result from direct trauma, such as falls, sports injuries, or twisting motions. Axial forces (e.g., landing on the foot) or bending stresses can cause the bone to buckle. Underlying bone weakness from conditions like osteoporosis may increase susceptibility, though these fractures are more common in pediatric populations with developing bone structure.

Risk Factors

• Participation in high-impact activities (e.g., contact sports, jumping)
• Pediatric age group, due to softer bone composition
• Previous lower leg fractures or related injuries
• Poor bone health from inadequate nutrition or chronic conditions

Symptoms

• Pain and tenderness localized to the lower right leg or ankle
• Swelling and bruising around the affected area
• Difficulty bearing weight or walking on the right leg
• Possible visible deformity or instability (less common than in complete fractures)

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays, are used to confirm the torus fracture and evaluate its severity. The closed nature of the fracture and initial encounter status are documented to guide management.

Treatment Options

Treatment typically includes immobilization with a cast or splint to stabilize the bone and allow healing. Pain management with analgesics may be recommended. Follow-up care focuses on monitoring healing and restoring function through gradual weight-bearing and physical therapy as tolerated.

Prognosis and Follow-Up

Prognosis is generally favorable, with most torus fractures healing within 4–6 weeks. Follow-up appointments monitor healing progress via imaging and assess functional recovery. Long-term complications are rare, but adherence to immobilization and activity restrictions is important to prevent displacement.

Complications

• Delayed healing or nonunion (rare)
• Malalignment if immobilization is inadequate
• Chronic pain or stiffness in the ankle joint
• Recurrence with repeated trauma to the area

Lifestyle & Prevention

• Use protective gear during high-impact activities (e.g., helmets, pads)
• Ensure adequate calcium and vitamin D intake for bone health
• Practice safe movement techniques to avoid falls or twisting injuries
• Gradually return to weight-bearing activities as directed by a healthcare provider

When to Seek Professional Help

Seek immediate medical attention if pain worsens, swelling increases, or mobility is severely limited. Contact a provider if numbness, tingling, or discoloration of the foot occurs, as these may indicate nerve or vascular involvement.

Tips for Medical Coders

Document the torus fracture type, right tibia location, closed status, and initial encounter clearly. Ensure the fracture is distinguished from other tibial injuries (e.g., complete fractures) to support accurate coding. Include details on imaging or clinical findings that confirm the diagnosis.
