S72.113N Displaced fracture of greater trochanter of unspecified femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Name of the Condition

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

Summary

A displaced fracture of the greater trochanter of the femur is a break in the bony prominence on the upper part of the thigh bone (femur) near the hip joint, where the bone fragment has moved out of its normal position. This code specifies a subsequent encounter for an open fracture (type IIIA, IIIB, or IIIC) with nonunion, indicating the fracture has not healed properly after an initial injury. Open fractures involve skin or soft tissue damage, and nonunion refers to a failure of the bone to fuse over time.

Causes

Displaced fractures of the greater trochanter commonly result from direct trauma, such as falls or high-impact injuries. They can also occur in individuals with weakened bones due to conditions like osteoporosis, where even minor stress may cause a fracture with displacement. Open fractures (type IIIA, IIIB, or IIIC) may result from the same mechanisms, with the added factor of significant skin or soft tissue damage. Nonunion can develop due to poor blood supply, infection, or inadequate initial treatment.

Risk Factors

• Advanced age, particularly in postmenopausal women with osteoporosis.
• Conditions that weaken bones, such as osteoporosis, cancer, or metabolic disorders.
• History of previous fractures or falls.
• Sedentary lifestyle or limited mobility.
• High-impact activities or trauma.
• Poor initial fracture management or infection.

Symptoms

• Persistent hip or groin pain, often worsened by movement.
• Inability to bear weight on the affected leg.
• Swelling, bruising, or deformity around the hip.
• Leg shortening or external rotation.
• Open wound or exposed bone (in open fractures).
• Delayed healing or persistent pain indicating nonunion.

Diagnosis

Physical examination to assess pain, range of motion, and deformity. Imaging studies, including X-rays or CT scans, to confirm the fracture, assess displacement, and evaluate for nonunion. Evaluation of the open wound to classify the fracture type (IIIA, IIIB, or IIIC) based on soft tissue damage and contamination. Assessment of healing progress through serial imaging.

Treatment Options

• Surgical intervention to realign and stabilize the fracture, often with internal fixation devices.
• Debridement and wound care for open fractures to prevent infection.
• Bone grafting or other techniques to promote union in cases of nonunion.
• Antibiotics for open fractures to treat or prevent infection.
• Physical therapy to restore mobility and strength after healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the success of treatment, and the presence of complications. Nonunion may require additional interventions, and open fractures carry a risk of infection or delayed healing. Regular follow-up with imaging and clinical assessments is necessary to monitor healing and address complications. Long-term mobility and function may be affected, particularly if arthritis or chronic pain develops.

Complications

• Nonunion or delayed union of the fracture.
• Infection, especially with open fractures.
• Arthritis or chronic pain in the hip joint.
• Nerve or blood vessel damage.
• Limited mobility or functional impairment.
• Need for additional surgeries.

Lifestyle & Prevention

• Maintain bone health through adequate calcium and vitamin D intake.
• Engage in weight-bearing exercises to strengthen bones.
• Use fall prevention strategies, such as home modifications and assistive devices.
• Avoid high-impact activities that increase fracture risk.
• Manage underlying conditions like osteoporosis with appropriate treatment.

When to Seek Professional Help

Seek immediate medical attention for severe hip pain, inability to bear weight, or visible bone exposure. Follow up with a healthcare provider if pain persists, swelling worsens, or there are signs of infection (e.g., fever, redness, drainage). Regular check-ups are important for monitoring healing and addressing complications.

Tips for Medical Coders

Document the fracture type (IIIA, IIIB, or IIIC) and the presence of nonunion clearly. Specify that this is a subsequent encounter, indicating ongoing care for a previously treated fracture. Ensure the open fracture classification aligns with the extent of soft tissue damage and contamination. Code S72.113N is used when the femur side is unspecified and the fracture is a subsequent encounter for an open fracture with nonunion.
