S72.064M Nondisplaced articular fracture of head of right femur, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Nondisplaced articular fracture of head of right femur, subsequent encounter for open fracture type I or II with nonunion

Summary

A nondisplaced articular fracture of the head of the right femur involves a break in the femoral head, the rounded upper portion of the thigh bone that forms part of the hip joint, where the fracture fragments remain in their normal alignment. This injury affects the joint surface and is classified as an open fracture type I or II with nonunion, indicating a break in the skin with minimal contamination and failure of the fracture to heal. Prompt evaluation is essential to determine the extent of the injury and guide appropriate management.

Causes

High-impact trauma, such as falls or motor vehicle accidents. Low-impact trauma in individuals with weakened bones (e.g., osteoporosis). Direct force to the hip region.

Risk Factors

• Advanced age, particularly in those over 65
• Osteoporosis or other bone density disorders
• Female gender, due to higher osteoporosis prevalence
• History of prior fractures or bone diseases
• Participation in high-risk activities (e.g., contact sports)
• Poor blood supply to the femoral head
• Inadequate initial treatment or immobilization

Symptoms

• Persistent hip or groin pain
• Inability to bear weight on the affected leg
• Swelling, bruising, or tenderness around the hip
• Leg shortening or external rotation of the affected limb
• Limited range of motion in the hip joint
• Open wound in the hip region (for open fracture)
• Signs of nonunion, such as persistent pain or instability

Diagnosis

Physical examination to assess pain, mobility, and limb alignment. Imaging studies, including X-rays or CT scans, to visualize the fracture and assess for nonunion. Evaluation of the open wound for type and contamination. Assessment of healing progress through serial imaging.

Treatment Options

• Surgical intervention, such as internal fixation or bone grafting, to promote union
• Antibiotics to prevent or treat infection in open fractures
• Pain management with analgesics
• Physical therapy to restore mobility and strength
• Weight-bearing restrictions as advised
• Possible revision surgery if initial treatment fails

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, patient factors, and response to treatment. Nonunion may require additional interventions. Regular follow-up with imaging to monitor healing is essential. Long-term outcomes may include persistent pain, arthritis, or functional limitations.

Complications

• Nonunion or delayed union
• Infection, particularly in open fractures
• Avascular necrosis of the femoral head
• Post-traumatic arthritis
• Chronic pain or instability
• Need for additional surgeries

Lifestyle & Prevention

• Maintain bone health with calcium and vitamin D
• Engage in weight-bearing exercises to strengthen bones
• Use protective gear during high-risk activities
• Address fall risks in older adults (e.g., home modifications)
• Avoid smoking, which impairs bone healing

When to Seek Professional Help

Seek immediate care for severe hip pain, inability to bear weight, or open wounds. Follow up with a healthcare provider if pain persists, swelling increases, or mobility worsens after initial treatment.

Tips for Medical Coders

Document the fracture type (open I or II), laterality (right femur), and the presence of nonunion. Specify "subsequent encounter" to indicate ongoing care for the fracture. Ensure documentation supports the open fracture classification and nonunion status for accurate coding.
