osteolysis

Thân thiện

A patient's X-ray shows signs of osteolysis in the hip joint.

Definition

1. Noun:
   • The pathological dissolution or destruction of bone tissue: "Osteolysis" refers to the process where bone is broken down and absorbed by the body, typically as a result of disease, infection, or compromised blood supply. It is a resorptive process that weakens the bone structure.

Usage Examples

• Noun:
  • The patient's chronic infection led to significant osteolysis in the jaw.
  • Radiographs revealed areas of osteolysis around the implant, indicating a potential complication.
  • Osteolysis is a common finding in certain types of bone cancers and metabolic bone diseases.

Advanced Usage

• "aseptic osteolysis": bone destruction occurring in the absence of a clinically detectable infection, often associated with prosthetic wear debris.
  • Aseptic osteolysis is a major cause of long-term failure in joint replacements.
• "pressure osteolysis": bone resorption caused by continuous mechanical pressure.
  • Pressure osteolysis can occur under orthodontic appliances or ill-fitting dentures.

Variants and Related Words

• Osteolytic (adj): relating to or characterized by osteolysis.
  • The tumor had an osteolytic effect on the surrounding bone.
• Osteoclast (n): a type of bone cell that breaks down bone tissue, responsible for the resorptive activity in osteolysis.

Synonyms

• Bone resorption: the general process of bone breakdown.
• Bone destruction: a more general term for the damaging of bone tissue.

Related Phrases and Terms

• Periprosthetic osteolysis: bone loss occurring around a prosthetic implant.
  • The surgeon monitored the patient for signs of periprosthetic osteolysis.
• Disuse osteolysis/atrophy: bone loss resulting from lack of mechanical stress or immobilization.
  • Prolonged bed rest can lead to disuse osteolysis.

Notes

• "Osteolysis" is primarily a medical term used in fields like orthopedics, radiology, and dentistry. It describes a specific pathological process, distinct from the normal bone remodeling carried out by osteoclasts and osteoblasts. The condition can be localized or generalized and is a key diagnostic feature in various imaging studies.
