S72.063N Displaced articular fracture of head of unspecified femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Name of the Condition

• Displaced articular fracture of head of unspecified femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Summary

A displaced articular fracture of the head of the unspecified femur involves a break in the femoral head, the rounded upper portion of the thigh bone that forms part of the hip joint, with the fracture fragments shifted out of their normal alignment. This injury disrupts joint mechanics and may result from trauma or weakened bone structure. The fracture is classified as open (type IIIA, IIIB, or IIIC), indicating significant soft tissue damage and contamination, and is complicated by nonunion, where the bone fails to heal properly. Prompt evaluation is necessary to assess the extent of displacement, wound severity, and guide treatment.

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 fracture management

Symptoms

• Persistent hip or groin pain, often severe
• 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
• Visible wound or open fracture site (for open fractures)
• 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, assess displacement, and confirm nonunion. Evaluation of the open wound for type (IIIA, IIIB, or IIIC) and contamination. Assessment of blood supply and soft tissue damage. Review of prior treatment and healing history.

Treatment Options

Surgical intervention to realign and stabilize the fracture, often with internal fixation or joint replacement. Debridement of the open wound to remove contaminated tissue. Bone grafting or other techniques to promote healing in cases of nonunion. Antibiotics to prevent or treat infection. Physical therapy to restore mobility and strength. Pain management and wound care.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, type of open wound, and success of treatment. Nonunion may require additional procedures. Regular follow-up with imaging to monitor healing. Long-term management may include physical therapy and activity modifications. Complications like infection or arthritis can affect outcomes.

Complications

• Infection (especially with open fractures)
• Nonunion or malunion of the fracture
• Avascular necrosis (loss of blood supply to the femoral head)
• Post-traumatic arthritis
• Chronic pain or instability
• Nerve or vascular damage
• Limited mobility or disability

Lifestyle & Prevention

• Maintain bone health through diet (calcium, vitamin D) and exercise.
• Avoid high-risk activities that increase fracture risk.
• Use protective gear during sports or activities.
• Address underlying bone conditions (e.g., osteoporosis) with medical treatment.
• Follow post-treatment guidelines for weight-bearing and activity.

When to Seek Professional Help

Seek immediate medical attention for severe hip pain, inability to bear weight, or visible open wounds. Consult a healthcare provider if pain persists, swelling worsens, or mobility does not improve with treatment. Watch for signs of infection (fever, increased redness, pus) or nonunion (persistent pain, instability).

Tips for Medical Coders

Document the fracture type (displaced articular), femur involvement (unspecified), encounter type (subsequent), open fracture classification (IIIA, IIIB, or IIIC), and nonunion status. Ensure detailed clinical notes support the open fracture type and nonunion diagnosis. Code S72.063N is specific to subsequent encounters with nonunion; verify the sequence and timing of encounters.
