S92.043B Displaced other fracture of tuberosity of unspecified calcaneus, initial encounter for open fracture

Name of the Condition

• Displaced other fracture of tuberosity of unspecified calcaneus, initial encounter for open fracture

Summary

This condition involves a displaced fracture of the tuberosity of the calcaneus (heel bone) where the fracture is open (exposing the bone or underlying tissue) and is classified as "other" to denote a specific type of tuberosity injury. The term "unspecified" indicates the side of the calcaneus is not documented, and "initial encounter" specifies this is the first episode of care for the open fracture. Displacement means the bone fragments are not aligned, which may complicate healing and require intervention.

Causes

High-impact trauma, such as falls, direct blows to the heel, or severe twisting injuries, can cause this fracture. Open fractures often result from trauma that breaks the skin, exposing the fracture site. Repetitive stress or sudden force during activities like jumping or running may also lead to injury, particularly if the skin is compromised.

Risk Factors

• Participation in high-impact sports (e.g., running, basketball)
• Osteoporosis or weakened bone density
• Poor footwear or inadequate foot support
• Occupational hazards involving heavy lifting or falls
• Previous foot or ankle injuries

Symptoms

• Severe heel pain, especially with weight-bearing
• Swelling and bruising around the heel
• Visible wound or open skin at the fracture site
• Difficulty walking or standing
• Possible deformity or abnormal positioning of the heel

Diagnosis

Physical examination assesses pain, swelling, and range of motion, with attention to the open wound and potential contamination. Imaging, typically X-rays, confirms the fracture and evaluates displacement. CT scans may be used for detailed assessment of complex fractures. The open nature of the fracture requires evaluation for infection or tissue damage.

Treatment Options

• Immediate wound care to clean and dress the open fracture
• Antibiotics to prevent infection
• Immobilization with a cast or splint to stabilize the fracture
• Pain management with medications or ice therapy
• Surgical intervention to realign and fix the fracture, if necessary
• Tetanus prophylaxis, if indicated

Prognosis and Follow-Up

Healing depends on the severity of displacement, wound contamination, and treatment. Open fractures carry a higher risk of infection, which may delay recovery. Follow-up care includes monitoring for signs of infection, assessing fracture alignment, and planning rehabilitation. Physical therapy may be needed to restore strength and mobility once healing progresses.

Complications

• Infection at the fracture site
• Delayed healing or nonunion
• Nerve or blood vessel damage
• Chronic pain or arthritis
• Difficulty with weight-bearing or walking

Lifestyle & Prevention

• Wear supportive footwear during high-impact activities
• Maintain bone health through diet and exercise
• Use proper techniques to avoid falls or direct trauma to the heel
• Seek prompt care for foot injuries to prevent open fractures

When to Seek Professional Help

Seek immediate medical attention if you experience severe heel pain, swelling, an open wound, or difficulty walking after an injury. Signs of infection, such as increased redness, pus, or fever, also require urgent evaluation.

Tips for Medical Coders

Document the fracture type (displaced, other), the calcaneus tuberosity involvement, the open nature of the fracture, and the initial encounter status. Specify if the calcaneus side is known, as "unspecified" is used only when the side cannot be determined. Ensure wound characteristics and treatment align with the open fracture classification.
