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

Name of the Condition

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

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 a subsequent encounter for an open fracture (type I or II) with malunion, indicating it is a follow-up visit for a previously treated open fracture where the bone has healed in a non-anatomical position. The term "unspecified femur" means the side (right or left) is not documented, and "open fracture type I or II" refers to a fracture with a skin wound that is limited in size or contamination.

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. Malunion occurs when the bone heals in a misaligned position, often due to inadequate initial reduction or poor healing.

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 exposure.
• Poor initial fracture management leading to malunion.

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.
• Limited range of motion in the hip joint.
• Visible or palpable bony prominence at the fracture site.

Diagnosis

Physical examination to assess pain, range of motion, and deformity. Imaging studies, including X-rays or CT scans, to confirm the fracture, assess malunion, and evaluate bone healing. Review of prior treatment records to determine the fracture type and encounter status. Clinical correlation with the patient’s history of open fracture and healing progress.

Treatment Options

• Pain management with analgesics or anti-inflammatory medications.
• Physical therapy to improve mobility, strength, and function.
• Orthopedic evaluation for possible surgical intervention if malunion causes significant functional impairment.
• Assistive devices (e.g., crutches, walkers) to reduce weight-bearing stress.
• Monitoring for complications such as infection or further displacement.

Prognosis and Follow-Up

Prognosis depends on the degree of malunion, patient age, and overall health. Most patients experience improved function with conservative management, but severe malunion may require surgery. Follow-up visits are essential to monitor healing, assess functional recovery, and adjust treatment plans. Long-term outcomes may include residual pain or limited mobility, particularly if the malunion is untreated.

Complications

• Chronic pain or discomfort.
• Reduced mobility or gait abnormalities.
• Increased risk of future fractures due to weakened bone structure.
• Potential need for surgical correction of malunion.
• Rarely, infection or nonunion if the initial fracture was open.

Lifestyle & Prevention

• Engage in weight-bearing exercises to strengthen bones and improve balance.
• Ensure adequate calcium and vitamin D intake to support bone health.
• Use fall prevention strategies, such as removing tripping hazards and wearing supportive footwear.
• Maintain a healthy weight to reduce stress on bones and joints.
• Follow post-fracture care guidelines to optimize healing and minimize malunion risk.

When to Seek Professional Help

Seek immediate medical attention if you experience severe hip pain, inability to bear weight, or signs of infection (e.g., fever, redness, drainage) at the fracture site. Contact your healthcare provider if pain worsens, mobility declines, or you notice new deformities or swelling.

Tips for Medical Coders

Document the encounter as a subsequent visit for an open fracture (type I or II) with malunion. Ensure the record specifies the fracture type, malunion status, and that this is a follow-up encounter. Include details on the fracture’s history, healing progress, and any functional limitations to support code assignment. Verify that the "unspecified femur" designation is appropriate if the side is not documented.
