S72.333Q Displaced oblique fracture of shaft of unspecified femur, subsequent encounter for open fracture type I or II with malunion

Name of the Condition

• Displaced Oblique Fracture of Shaft of Unspecified Femur, Subsequent Encounter for Open Fracture Type I or II with Malunion

Summary

A displaced oblique fracture of the shaft of the unspecified femur is a break in the long, central portion of the thigh bone where the fracture line runs at an angle, and the bone fragments are misaligned. This type of fracture involves the diaphysis (main structural part) of the femur and is classified as an open fracture (type I or II) during a subsequent encounter, indicating a break in the skin with minimal or moderate soft tissue damage. The term "malunion" refers to improper healing of the fracture, where the bone has healed in a non-anatomical position.

Causes

Such fractures often 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.

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.
• Visible deformity or shortening of the leg (due to displacement).
• Possible numbness or tingling if nerve involvement occurs.
• Signs of malunion, such as persistent pain or functional impairment.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays to evaluate fracture healing and malunion. Assessment of open wound status and soft tissue damage. Review of prior treatment and healing progress.

Treatment Options

• Orthopedic evaluation to determine management of malunion.
• Possible surgical intervention to correct alignment or stabilize the fracture.
• Physical therapy to improve mobility and strength.
• Pain management and wound care for open fracture sites.
• Monitoring for complications related to malunion or infection.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and functional impact. Follow-up care may include regular imaging to assess healing and rehabilitation progress. Long-term monitoring for arthritis or other complications may be necessary.

Complications

• Chronic pain or functional limitations due to malunion.
• Increased risk of future fractures.
• Nerve or vascular damage from the original injury.
• Infection at the open fracture site.
• Arthritis or joint stiffness in the affected leg.

Lifestyle & Prevention

• Avoid high-impact activities that risk further injury.
• Maintain bone health through diet and exercise.
• Use protective equipment during sports or work.
• Follow post-treatment guidelines to support proper healing.

When to Seek Professional Help

Seek immediate medical attention for severe pain, swelling, or signs of infection. Consult a healthcare provider if malunion symptoms worsen or if functional limitations persist.

Tips for Medical Coders

Document the fracture type (open, type I or II), the presence of malunion, and the subsequent encounter status. Ensure clinical notes specify the fracture's anatomical location, displacement, and healing status to support accurate coding.
