joint disease

joint disease

1-degenerative disease (osteoartheritis )
2- inflammatry disease (still disease ,RA)
3-infective disease (septic artheritis ,TB artheritis )
4-malignant disease (synovioma )
5-traumatic disease
6-congenital disease (displacement hip)
7-abnormal trabecular patteran (behejet disease

classification

Hypertrophic
Hallmarks
Bone production
Sclerosis
Infectious
Hallmark
Destruction of articular cortex
Erosive
Hallmark
Erosions

hypertrophic artheritis

Degenerative arthritis(osteoartheritis)
Primary
Secondary
Charcot arthropathy

primary digenerative artheritis :


Intrinsic degeneration of articular cartilage
Excessive wear and tear
Most commonly hips and knees


sencondary degenerative artheritis:

Another process destroys articular cartilage
Degenerative changes supervene
How to recognize
Atypical locations (knee)
Atypical appearance (Marked DJD of 1 hip)
Atypical age (DJD in 20 year-old

causes: of 2 degenerative artheritis

Trauma
Infection
Avascular necrosis
CPPD
RA
Hemophilia

osteoartheritis:
RADIOLOGICAL SIGN :
1-normal bone density
2-narrowing of the joint space
3- cyst formation in the bone due to erosion
4-osteolytic lesion
5-sclerosis of the bone later
6-osteophyte formation

charcots artheropathy : general:
Disturbance in sensation leads to multiple microfractures
Pain sensation intact from muscles and soft tissue
Causes
Shoulders – syrinx, spinal tumor
Hips – tertiary syphilis, diabetes
Feet – diabetes

X-ray findings
Fragmentation
Soft tissue swelling
Destruction of joint
Sclerosis
