S72.112R Displaced fracture of greater trochanter of left femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with malunion

Name of the Condition

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

Summary

A displaced fracture of the greater trochanter of the left femur is a break in the bony prominence on the upper part of the left thigh bone (femur) near the hip joint, where the bone fragment has moved out of its normal position. This code applies to a subsequent encounter for an open fracture (type IIIA, IIIB, or IIIC) that has healed with malunion, meaning the bone fragments have united in a non-anatomical position. Open fractures involve a break in the skin with significant soft tissue damage, and malunion indicates incomplete or abnormal healing.

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 may result from trauma that penetrates the skin, such as a fall onto a sharp object or a high-velocity injury. Malunion can develop if the fracture is not properly aligned during initial treatment or if healing is compromised.

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.
• Trauma involving open wounds, such as motor vehicle accidents or falls onto sharp surfaces.
• Inadequate initial fracture management or delayed treatment.

Symptoms

• Persistent hip or groin pain, often worsened by movement or weight-bearing.
• Inability to bear weight on the affected leg.
• Swelling, bruising, or deformity around the hip.
• Leg shortening or external rotation.
• Visible signs of prior open fracture (e.g., scarring, tissue damage).
• Functional limitations due to malunion, such as altered gait or reduced range of motion.

Diagnosis

Physical examination to assess pain, range of motion, and deformity. Imaging studies, including X-rays or CT scans, to confirm malunion and evaluate the extent of the previous open fracture. Review of prior treatment records to determine the fracture type and healing status. Assessment of functional impact, such as gait analysis or mobility testing.

Treatment Options

• Pain management with analgesics or anti-inflammatory medications.
• Physical therapy to improve strength, mobility, and function.
• Orthopedic evaluation to determine if surgical intervention (e.g., osteotomy, hardware removal) is needed to correct malunion.
• Assistive devices (e.g., crutches, walkers) to support weight-bearing.
• Monitoring for complications, such as infection or further displacement.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion, functional impact, and response to treatment. Most patients experience improved pain and function with rehabilitation, though some may have persistent limitations. Follow-up imaging may be recommended to assess healing and alignment. Long-term monitoring for arthritis or other complications related to malunion is important.

Complications

• Chronic pain or discomfort.
• Reduced mobility or gait abnormalities.
• Increased risk of future fractures due to weakened bone structure.
• Arthritis in the hip joint.
• Nerve or vascular damage from the original open fracture.
• Infection or delayed healing if the initial fracture was severe.

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 rehabilitation plans to optimize healing and function.

When to Seek Professional Help

Seek medical attention if you experience worsening pain, new swelling, or difficulty bearing weight. Contact a healthcare provider if you notice signs of infection (e.g., redness, pus) or if functional limitations persist despite treatment. Prompt evaluation is important for managing complications or adjusting treatment plans.

Tips for Medical Coders

Document the subsequent encounter status, open fracture type (IIIA, IIIB, or IIIC), and malunion clearly in the medical record. Ensure the fracture is confirmed as displaced and specify the left femur. Include details about the healing process and any functional impact to support code assignment. Verify that the encounter is for aftercare or follow-up of the fracture, not an initial treatment phase.
