ICD-10: M84.758

The ICD-10 code M84.758 refers to a complete oblique atypical femoral fracture specifically located in the left leg. This classification is part of the broader category of atypical femoral fractures, which are characterized by specific features that differentiate them from typical femoral fractures.

Clinical Description

Definition

An atypical femoral fracture is defined as a fracture of the femur that occurs with minimal or no trauma, often associated with long-term bisphosphonate therapy or other osteoporosis treatments. The term "complete oblique" indicates that the fracture line runs diagonally across the femur and extends through the entire thickness of the bone, which can complicate healing and may require surgical intervention.

Characteristics

• Location: The fracture occurs in the femur, specifically on the left side of the body.
• Type: Classified as a complete fracture, meaning the bone is broken into two or more pieces.
• Fracture Pattern: The oblique nature of the fracture suggests a diagonal break, which can affect the stability of the bone and the surrounding soft tissues.

Symptoms

Patients with a complete oblique atypical femoral fracture may present with:
- Severe pain in the thigh or groin area.
- Swelling and bruising around the fracture site.
- Inability to bear weight on the affected leg.
- A noticeable deformity in the leg, depending on the severity of the fracture.

Risk Factors

Several factors may contribute to the occurrence of atypical femoral fractures, including:
- Long-term use of bisphosphonates or other medications for osteoporosis.
- Low bone mineral density.
- Previous history of fractures.
- Certain medical conditions that affect bone health.

Diagnosis and Management

Diagnosis

Diagnosis typically involves:
- Clinical Evaluation: A thorough history and physical examination to assess symptoms and risk factors.
