Definition

Noun: A fatigue fracture is a type of bone break or crack that develops gradually due to repeated stress or overuse, rather than from a single, specific traumatic injury. It is also commonly known as a stress fracture.

Usage

This term is used primarily in medical, sports medicine, and occupational health contexts to describe an injury caused by cumulative micro-damage to a bone. - It is a countable noun. - It is often modified by adjectives specifying the location (e.g., tibial fatigue fracture) or the activity that caused it.

Examples

• The runner was diagnosed with a fatigue fracture in her metatarsal after increasing her weekly mileage too quickly.
• Military recruits are susceptible to fatigue fractures in the lower legs due to the intense, repetitive training.
• Prevention programs focus on proper rest and equipment to avoid fatigue fractures.

Advanced Usage

• Clinical Diagnosis: In medical reporting, the term is used to distinguish this injury from acute traumatic fractures. For example: "Radiographic findings are consistent with a fatigue fracture of the femoral neck."
• Biomechanics: The term appears in scientific literature discussing the material failure of bone under cyclic loading.

Variants and Related Words

• Stress Fracture: The most common synonym for fatigue fracture. The terms are often used interchangeably in general contexts.
• Insufficiency Fracture: A related but distinct term for a fracture that occurs in weakened bone (e.g., from osteoporosis) under normal stress, as opposed to a fatigue fracture, which occurs in normal bone under excessive, repetitive stress.

Synonyms

• Stress fracture
• March fracture (a specific historical term for fatigue fractures in the metatarsals of soldiers)

Notes on Meaning

The core meaning emphasizes the cause (repetitive stress/overuse) rather than the appearance of the break. It is a subset of the broader category of fractures.

Noun

1. fracture resulting from excessive activity rather than a specific injury
