S72.323M Displaced transverse fracture of shaft of unspecified femur, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Displaced Transverse Fracture of Shaft of Unspecified Femur, Subsequent Encounter for Open Fracture Type I or II with Nonunion (ICD-10 Code: S72.323M)

Summary

A displaced transverse fracture of the femur shaft involves a horizontal break across the central portion of the thigh bone, with the bone fragments misaligned. This fracture is classified as an open injury (type I or II), meaning the overlying skin is breached, and it is documented during a subsequent encounter for treatment. The presence of nonunion indicates the fracture has failed to heal properly, requiring ongoing management to address the lack of bony consolidation.

Causes

Such fractures typically result from high-impact trauma, such as motor vehicle accidents, falls from significant heights, or direct force to the thigh. Rotational or axial loading injuries (e.g., during sports or industrial accidents) can also cause this type of break. Open fractures occur when the trauma forces the bone through the skin or when external objects penetrate the tissue. Nonunion may develop due to inadequate stabilization, poor blood supply, infection, or other factors that impede healing.

Risk Factors

• Participation in high-impact sports or activities.
• Osteoporosis or other bone-weakening conditions.
• Advanced age, due to decreased bone density.
• Prior history of fractures or bone abnormalities.
• Trauma or accidents involving significant force.
• Inadequate initial fracture management or complications during healing.

Symptoms

• Persistent pain at the fracture site, often worsening with movement.
• Swelling, bruising, or tenderness around the fracture area.
• Inability to bear weight on the affected leg.
• Visible deformity or shortening of the leg (due to displacement).
• Possible numbness or tingling if nerve involvement occurs.
• Signs of nonunion, such as lack of healing progress over time.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays to visualize the fracture and assess for nonunion. Additional imaging (e.g., CT scans) may be used to evaluate bone healing and soft tissue involvement. Laboratory tests to check for infection or metabolic issues that could affect healing.

Treatment Options

Treatment focuses on promoting fracture union and managing the open fracture. Options may include surgical intervention (e.g., internal fixation, bone grafting) to stabilize the fracture and encourage healing. Antibiotics or wound care may be necessary for open fractures. Physical therapy to restore mobility and strength once healing progresses. Monitoring for complications, such as infection or further displacement.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the success of treatment, and the patient’s overall health. Nonunion may require additional interventions to achieve healing. Regular follow-up appointments with imaging to assess progress are essential. Long-term monitoring for functional recovery and potential complications, such as arthritis or chronic pain.

Complications

• Nonunion or delayed union of the fracture.
• Infection at the fracture site or from the open wound.
• Nerve or vascular damage due to the initial trauma or surgery.
• Chronic pain or instability in the affected leg.
• Post-traumatic arthritis or reduced mobility.
• Need for additional surgeries if healing does not occur.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Follow prescribed weight-bearing restrictions to protect the healing bone.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Use protective equipment during sports or activities with fall risks.
• Address underlying conditions (e.g., osteoporosis) to reduce fracture risk.

When to Seek Professional Help

Seek immediate medical attention if experiencing severe pain, swelling, or deformity. Contact a healthcare provider if symptoms worsen, or if there are signs of infection (e.g., fever, increased redness, drainage). Follow up as scheduled to monitor healing and address any concerns about nonunion or complications.

Tips for Medical Coders

Document the encounter as a subsequent visit for an open fracture type I or II with nonunion. Ensure the fracture is classified as displaced and transverse, involving the shaft of the unspecified femur. Note the presence of nonunion and the open fracture type to support accurate coding. Include details on treatment provided and any complications affecting the healing process.
