S72.113H Displaced fracture of greater trochanter of unspecified femur, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Displaced fracture of greater trochanter of unspecified femur, subsequent encounter for open fracture type I or II with delayed healing

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 type of fracture is classified as an open fracture (type I or II) during a subsequent encounter, meaning the overlying skin was compromised but the wound is limited. The term "delayed healing" indicates the fracture has not progressed as expected during the normal healing timeline. This condition typically results from trauma or weakened bone structure and may involve significant displacement of the bone fragment.

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 I or II) may result from the same mechanisms, with the added factor of skin penetration by the fractured bone or associated trauma. Delayed healing may be due to factors such as poor blood supply, infection, or inadequate immobilization.

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 nutrition or smoking, which can impair bone healing.

Symptoms

• Severe 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.
• Persistent pain or instability despite initial treatment.
• Possible signs of infection, such as redness, warmth, or drainage (if open fracture present).

Diagnosis

Physical examination to assess pain, range of motion, and deformity. Imaging studies, including X-rays or CT scans, to confirm the fracture and evaluate displacement. Assessment of the open wound (if present) to determine type (I or II) and check for signs of infection or delayed healing. Review of prior treatment and healing progress to classify the encounter as "subsequent" with delayed healing.

Treatment Options

• Immobilization with a brace or cast to stabilize the fracture.
• Surgical intervention, such as internal fixation, if displacement is significant or healing is delayed.
• Antibiotics for open fractures to prevent infection.
• Pain management with medications.
• Physical therapy to restore mobility and strength once healing allows.
• Nutritional support or supplements to promote bone healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, patient age, and overall health. Delayed healing may require extended treatment or additional interventions. Regular follow-up with imaging to monitor progress is essential. Most patients can regain function with proper care, but recovery may be prolonged. Complications like infection or nonunion (failure to heal) can affect outcomes.

Complications

• Infection, especially with open fractures.
• Nonunion (failure of the fracture to heal).
• Malunion (healing in an incorrect position).
• Chronic pain or arthritis in the hip joint.
• Limited mobility or gait abnormalities.
• Nerve or blood vessel damage (rare).

Lifestyle & Prevention

• Maintain bone health with calcium and vitamin D intake.
• Engage in weight-bearing exercises to strengthen bones.
• Use assistive devices (e.g., canes, walkers) to prevent falls.
• Address underlying conditions like osteoporosis with medical treatment.
• Avoid high-impact activities that increase fracture risk.
• Ensure proper nutrition and avoid smoking, which impairs healing.

When to Seek Professional Help

Seek immediate medical attention for severe hip pain, inability to bear weight, or signs of infection (e.g., fever, drainage, redness). Contact a healthcare provider if pain persists or worsens despite treatment, or if there is new swelling or deformity. Follow up as scheduled to monitor healing progress.

Tips for Medical Coders

Document the fracture type (open I or II), encounter stage (subsequent), and delayed healing clearly. Include details on the fracture's displacement, treatment provided, and any complications. Ensure the "unspecified femur" designation is used only when the side (right/left) is not documented. Verify that the open fracture classification aligns with clinical findings and that delayed healing is supported by imaging or clinical assessment.
