S72.326A Nondisplaced transverse fracture of shaft of unspecified femur, initial encounter for closed fracture

Name of the Condition

• Nondisplaced Transverse Fracture of Shaft of Unspecified Femur, Initial Encounter for Closed Fracture (ICD-10 Code: S72.326A)

Summary

A nondisplaced transverse fracture of the femur shaft is a break in the long, central portion of the thigh bone where the fracture line runs horizontally across the bone, and the bone fragments remain aligned without separation. This type of fracture involves the diaphysis (main structural part) of the femur and is classified as closed (no open wound) and initial encounter (first treatment episode). The fracture may be associated with soft tissue injury but does not involve displacement of the bone fragments.

Causes

Such fractures typically result from high-impact trauma, such as motor vehicle accidents, falls from significant heights, or direct blows to the thigh. Rotational forces or axial loading (e.g., during sports or industrial injuries) can also cause this type of break. The trauma must be sufficient to fracture the bone but not severe enough to displace the fragments.

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.

Symptoms

• Sharp, localized pain in the thigh.
• Swelling, bruising, or tenderness around the fracture site.
• Inability to bear weight on the affected leg.
• Possible numbness or tingling if nerve involvement occurs (less common in nondisplaced fractures).
• Minimal visible deformity (compared to displaced fractures).

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays to visualize the fracture line and confirm nondisplacement. Additional imaging (e.g., CT or MRI) may be used to evaluate soft tissue damage or associated injuries. Clinical correlation with the mechanism of injury and patient history is essential.

Treatment Options

• Immobilization with a cast, brace, or traction to stabilize the fracture and promote healing.
• Pain management with analgesics or anti-inflammatory medications.
• Physical therapy to restore mobility and strength once healing progresses.
• Surgical intervention (e.g., internal fixation) may be considered if stability is compromised or if there is risk of displacement.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative management, though recovery time varies based on patient factors and fracture severity. Follow-up imaging (e.g., X-rays) is typically performed to monitor healing progress. Long-term outcomes depend on adherence to treatment, rehabilitation, and absence of complications.

Complications

• Delayed union or nonunion of the fracture.
• Malunion (healing in an abnormal position).
• Infection (rare in closed fractures).
• Nerve or vascular injury (if trauma was severe).
• Post-traumatic arthritis (if joint involvement occurs).

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain bone health through adequate calcium and vitamin D intake.
• Use protective equipment during sports or high-risk activities.
• Address fall risks in older adults (e.g., home modifications, balance training).

When to Seek Professional Help

Seek immediate medical attention if symptoms worsen (e.g., increased pain, swelling, or numbness), if weight-bearing is impossible, or if there are signs of infection (e.g., fever, redness). Follow up with a healthcare provider as scheduled to monitor healing.

Tips for Medical Coders

Document the fracture type (nondisplaced transverse), bone involved (unspecified femur), encounter type (initial), and fracture status (closed). Ensure clinical documentation specifies the absence of displacement and confirms the fracture is closed. Code S72.326A is specific to the initial encounter for a closed, nondisplaced transverse fracture of the femur shaft; subsequent encounters or complications would use different codes.
