S72.335H Nondisplaced oblique fracture of shaft of left femur, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Nondisplaced Oblique Fracture of Shaft of Left Femur, Subsequent Encounter for Open Fracture Type I or II with Delayed Healing

Summary

A nondisplaced oblique fracture of the shaft of the left 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 remain aligned. This type of fracture involves the diaphysis (main structural part) of the femur and is classified as an open fracture type I or II, indicating a break in the skin with minimal contamination or soft tissue damage. The subsequent encounter with delayed healing indicates this is a follow-up visit for an injury that has not progressed as expected in the healing process.

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. The open nature of the fracture suggests the bone has pierced the skin, typically due to the force of the injury. Delayed healing may occur due to factors like poor blood supply, infection, or inadequate immobilization.

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.
• Poor nutrition or smoking, which can impair healing.
• Underlying medical conditions like diabetes or vascular disease.

Symptoms

• Persistent or worsening pain at the fracture site.
• Swelling, bruising, or tenderness around the fracture.
• Inability to bear weight on the affected leg.
• Possible numbness or tingling if nerve involvement occurs.
• Delayed healing signs, such as lack of callus formation on imaging.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays to visualize the fracture and assess healing progress. Additional tests like CT scans or MRIs may be used to evaluate soft tissue damage or complications. Blood tests to check for infection or nutritional deficiencies may also be performed.

Treatment Options

• Immobilization with a cast or brace to stabilize the fracture.
• Surgical intervention if healing does not progress, such as internal fixation.
• Antibiotics if infection is present.
• Physical therapy to restore strength and mobility once healing allows.
• Nutritional support or supplements to promote bone healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, overall health, and adherence to treatment. Delayed healing may require extended follow-up and adjustments to the treatment plan. Regular imaging and clinical assessments are necessary to monitor progress. Most patients eventually regain full function, but recovery may take longer than usual.

Complications

• Nonunion or malunion of the fracture.
• Infection at the fracture site.
• Nerve or vascular damage.
• Chronic pain or stiffness.
• Post-traumatic arthritis.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a balanced diet rich in calcium and vitamin D.
• Quit smoking to improve healing.
• Use protective gear during sports or high-risk activities.
• Address underlying bone conditions like osteoporosis.

When to Seek Professional Help

• Increasing pain, swelling, or redness at the fracture site.
• Signs of infection, such as fever or pus.
• Numbness, tingling, or weakness in the leg.
• Inability to bear weight after initial improvement.
• Concerns about delayed healing or complications.

Tips for Medical Coders

Document the fracture type (open I or II), laterality (left femur), and the presence of delayed healing. Include details about the encounter type (subsequent) and any contributing factors to delayed healing, such as infection or poor immobilization. Ensure documentation supports the open fracture classification and the reason for the delayed healing designation.
