[Cortical fissures in Paget's disease].

Area of Science:

• Orthopedics
• Rheumatology
• Bone Metabolism

Background:

• Paget's disease of bone is a chronic disorder characterized by abnormal bone remodeling.
• Cortical bone fissures are a recognized, though not fully understood, pathological feature in affected long bones.

Observation:

• Fissures in cortical bone were specifically located on the convex surfaces of the femur and tibia.
• The number of fissures observed did not correlate with the degree of diaphyseal (shaft) curvature.
• The primary clinical manifestation reported for these fissures was pain.

Findings:

• The natural course of these cortical bone fissures generally leads to recovery.
• Complete fractures, while rare, can occur as a complication.
• Degenerative changes were consistently absent in the observed cases.

Implications:

• Understanding fissure development aids in managing Paget's disease symptoms, particularly pain.
• Awareness of potential fracture risk is crucial for patient monitoring and treatment.
• The absence of degeneration suggests a distinct pathophysiology compared to other bone weakening conditions.
