S72.125M Nondisplaced fracture of lesser trochanter of left femur, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Nondisplaced fracture of lesser trochanter of left femur, subsequent encounter for open fracture type I or II with nonunion

Summary

This condition involves a break in the lesser trochanter of the left femur where the bone fragments remain in their normal anatomical position. The lesser trochanter is a bony prominence on the femur that serves as an attachment point for muscles. The fracture is classified as open (type I or II), meaning there is a wound communicating with the fracture site, and this is a subsequent encounter for treatment due to nonunion, where the fracture has failed to heal properly.

Causes

Nondisplaced fractures of the lesser trochanter typically result from trauma, such as falls or direct impact injuries. They can also occur in individuals with weakened bones due to conditions like osteoporosis, where even minor stress may cause a fracture. High-energy injuries, such as motor vehicle accidents, are common causes in younger populations. Nonunion may develop if the fracture does not heal adequately, often due to poor blood supply, infection, or inadequate immobilization.

Risk Factors

• Advanced age, particularly in postmenopausal women with osteoporosis.
• Conditions that weaken bones, such as osteoporosis, osteopenia, or metastatic bone disease.
• Participation in high-impact or contact sports.
• History of previous fractures or falls.
• Sedentary lifestyle or reduced bone density due to inactivity.
• Poor nutrition or smoking, which can impair bone healing.

Symptoms

• Persistent pain in the hip or groin area, often worsened by movement.
• Swelling and bruising around the hip that may not resolve.
• Difficulty in weight-bearing or limping on the affected side.
• Possible signs of nonunion, such as persistent pain months after the initial injury.

Diagnosis

Physical examination includes assessing range of motion, tenderness, and signs of nonunion. Imaging like X-rays or CT scans is used to confirm the fracture's location, displacement, and healing status. Additional tests, such as blood work, may be performed to rule out infection or assess bone health.

Treatment Options

Treatment focuses on promoting healing and addressing nonunion. Options may include:

• Surgical intervention, such as internal fixation or bone grafting, to stabilize the fracture.
• Immobilization with a cast or brace to limit movement.
• Pain management with medications.
• Physical therapy to restore strength and mobility once healing progresses.
• Addressing underlying conditions, such as osteoporosis, to support bone health.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. With proper intervention, many patients achieve healing and regain function, though recovery may take several months. Follow-up appointments are necessary to monitor healing through imaging and adjust treatment as needed.

Complications

• Nonunion or delayed healing, requiring additional treatment.
• Infection, particularly if the fracture is open.
• Chronic pain or reduced mobility.
• Muscle weakness or atrophy due to prolonged immobilization.
• Risk of future fractures due to weakened bone structure.

Lifestyle & Prevention

• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Engage in weight-bearing exercises to strengthen bones.
• Avoid high-impact activities that increase fracture risk.
• Use protective gear during sports or activities with fall risks.
• Quit smoking and limit alcohol, as both can impair bone healing.

When to Seek Professional Help

Seek medical attention if you experience:

• Persistent or worsening pain in the hip or groin.
• Swelling, bruising, or difficulty bearing weight that does not improve.
• Signs of infection, such as fever, redness, or drainage from a wound.
• New or worsening symptoms after initial treatment.

Tips for Medical Coders

Document the encounter as a subsequent visit for an open fracture type I or II with nonunion. Ensure the record specifies the fracture's nondisplaced nature, the open wound classification, and the presence of nonunion. Include details on treatment provided and any underlying conditions contributing to the nonunion.
