Overview

Back pain can be broadly classified into inflammatory, mechanical, degenerative, oncologic and infectious. Lumbar disc disease have been linked to genetic involvment. The risk of developing lumbar disc disease increases if found in other close relatives. Genes involved in the pathogenesis of back pain include, HLA-B27, SOX5, CCDC26/GSDMC, and DCC.

Pathophysiology

Physiology

The normal physiology of [name of process] can be understood as follows:

Pathogenesis

The exact pathogenesis of back pain depends on the underlying cause.
Back pain can be broadly classified into inflammatory, mechanical, degenerative, oncologic and infectious.^[1]^[2]^[3]^[4]

Type of back pain	Pathophysiology
Inflammatory	Inflammation of joints (sacroiliitis), inflammation of enthesis (spondyloarthritis)
Mechanical	Trauma, muscle sprain, extra weight on muscles (pregnancy, heavy lifting),
Oncologic	Lytic lesions in spine, nerve compression due to mass effect, pathologic fracture due to weakened bone
Degenerative	Cartilage degradation and bone remodeling decreases elasticity and causes pain , fractures can also occur due to osteoporosis,
Infectious	Infection involving spine, disc, joints, abscess formation.

Genetics

Genes involved in the pathogenesis of ankylosing spondylitis (AS) include Human Leukocyte Antigen–B27(HLA-B27).^[5]
Lumbar disc disease have been linked to genetic involvment. The risk of developing lumbar disc disease increases if found in other close relatives.^[6]
Genes involved in the pathogenesis of back pain include:^[7]
- SOX5
- CCDC26/GSDMC
- DCC

Associated Conditions

Conditions associated with back pain include:^[8]^[9]^[10]^[11]^[12]
- Heavy lifting
- Ligaments and muscle strain
- Back injuries/fractures
- Arthritis
- Osteoporosis
- Metastatic cancer
- Abnormal posturing
- Degenerative disc disease
- Depression
- Pregnancy
- Fibromyalgia
- Sciatica
- Spinal disc herniation
- Spinal stenosis

Gross Pathology

On gross pathology, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].

Microscopic Pathology

On microscopic histopathological analysis, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
