S72.323R Displaced transverse fracture of shaft of unspecified femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with malunion

Name of the Condition

• Displaced Transverse Fracture of Shaft of Unspecified Femur, Subsequent Encounter for Open Fracture Type IIIA, IIIB, or IIIC with Malunion (ICD-10 Code: S72.323R)

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 IIIA, IIIB, or IIIC), meaning the overlying skin is breached, and it is documented during a subsequent encounter for treatment. The fracture has malunion, indicating the bone has healed in a non-anatomic position, which may affect function or stability.

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, and malunion may develop if initial treatment was inadequate or the fracture was complex.

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.
• Delayed or inadequate initial fracture management.

Symptoms

• Persistent pain or discomfort at the fracture site.
• Swelling, bruising, or tenderness around the healed fracture.
• Visible deformity or limb shortening due to malunion.
• Limited range of motion or functional impairment.
• Possible skin changes or scarring from the open fracture.
• Nerve or vascular symptoms if malunion affects surrounding structures.

Diagnosis

Physical examination to assess alignment, function, and soft tissue status. Imaging tests such as X-rays or CT scans to evaluate fracture healing, malunion, and any residual displacement. Assessment of open fracture history and documentation of subsequent encounter details. Evaluation of functional impact and need for corrective intervention.

Treatment Options

• Orthopedic consultation to determine management of malunion.
• Possible surgical intervention (e.g., osteotomy, hardware revision) to correct alignment.
• Physical therapy to improve strength and mobility.
• Pain management and monitoring for complications.
• Wound care if residual soft tissue issues persist.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion, functional impact, and response to treatment. Follow-up care focuses on monitoring healing, assessing functional recovery, and addressing any residual symptoms. Long-term management may involve ongoing therapy or adaptive strategies to optimize mobility.

Complications

• Chronic pain or discomfort.
• Reduced mobility or functional limitations.
• Nerve or vascular damage from malunion.
• Increased risk of future fractures.
• Psychological impact due to prolonged recovery.

Lifestyle & Prevention

• Avoid high-impact activities that stress the affected limb.
• Engage in low-impact exercises to maintain strength and flexibility.
• Use assistive devices (e.g., braces, walkers) as recommended.
• Follow weight-bearing restrictions to protect healing bone.
• Maintain bone health through nutrition and exercise.

When to Seek Professional Help

Seek care if experiencing increased pain, swelling, or deformity; new numbness or tingling; difficulty bearing weight; or signs of infection (e.g., redness, drainage). Prompt evaluation is needed for worsening symptoms or functional decline.

Tips for Medical Coders

Document the fracture type (IIIA, IIIB, or IIIC), malunion status, and subsequent encounter details clearly. Ensure the open fracture classification and malunion are supported by clinical findings. Verify that the encounter is subsequent (not initial) and that all relevant details are captured to reflect the current state of the fracture and treatment.
