Bone sclerosis

Principle and interpretation

Degenerative change near an endplate or joint may be sclerotic. Other causes include some tumors; appearance, distribution and context are essential.

Indications, limitations and precautions

Bone sclerosis does not mean multiple sclerosis. A dense area is not necessarily painful or stronger; the radiologist assesses it alongside other findings.

Points to consider

An imaging sign describes an appearance that may have several explanations. Distribution, extent, other sequences and previous studies contribute to interpretation. The radiologist’s conclusion should be correlated with symptoms and examination before treatment is selected.

Role of TAGMED care

At TAGMED, assessment aims to understand symptoms, history and functional limitations. Manual care and osteopathy, motorized spinal decompression, laser and shockwave have different indications. The term described in this entry is not enough to select any of these modalities. Their relevance, limitations and possible contraindications should be discussed in relation to diagnosis and individual goals.

Related concepts and distinctions

These concepts belong to the same field, but are not synonyms.

• Extradural lesion — Abnormality outside the spinal dura, including in the epidural space, vertebrae or neighboring tissues.
• Osteolysis — Localized reduction or destruction of bone, seen as tissue loss or reduced density depending on the imaging technique.
• Intradural extramedullary lesion — Abnormality inside the dura but outside spinal cord tissue, potentially displacing or compressing the cord and roots.
