define degenerative
|
adj.
characterised by progressive deterioration and loss of function in the organs and tissues |
|
|
what structures are involved in musculoskeletal degeneration?
|
-bone
-joints ---cartilage ---ligaments ---tendons -muscle |
|
|
structures involved with musculoskeletal degeneration
-bone.... -joints ---cartilage ---ligaments ---tendons -muscle |
- reduction in density (osteoporosis)
- reactive changes to degeneration (sclerosis) |
|
|
structures involved with musculoskeletal degeneration
-bone -joints ---cartilage.... ---ligaments ---tendons -muscle |
- loss of articular cartilage, reduced joint space and range of movement
|
|
|
structures involved with musculoskeletal degeneration
-bone -joints ---cartilage ---ligaments..... ---tendons -muscle |
- tearing
- cystic changes - thickening/hypertrophy |
|
|
structures involved with musculoskeletal degeneration
-bone -joints ---cartilage ---ligaments ---tendons.... -muscle |
- tendinosis - degeneration of tendon's collagen, reduced strength, increased bulk, neovascularity
- tendon tear |
|
|
structures involved with musculoskeletal degeneration
-bone -joints ---cartilage ---ligaments ---tendons -muscle.... |
- reduction in bulk
- fatty infiltration |
|
|
what can x-rays show with regard to degenerative musculoskeletal disorders?
|
- good bony anatomical detail
- indication of bone density - can assess joint space (gives indication of cartilage but does not show cartilage) - demonstrates alignment of joint - can show reparative changes |
|
|
what are the classical features of osteoarthritis visible on an x-ray?
|
- joint space narrowing
- peripheral osteophytosis - subchondral sclerosis - subarticular cyst formation - subluxation |
|
|
what can CT scans show with regard to degenerative musculoskeletal disorders?
|
- good bony anatomical detail
- indication of bone density - can assess joint space (gives indication of cartilage but does not show cartilage) - demonstrates alignment of joint - can show reparative changes - relatively poor for muscle/tendons/ligaments |
|
|
what can USS scans show with regard to degenerative musculoskeletal disorders?
|
- no radiation
- good for superficial structures - does not penetrate bone - excellent assessment of tendons/ligaments - limited assessment of articular cartilage - can assess muscle |
|
|
what can MRI scans show with regard to degenerative musculoskeletal disorders?
|
- no radiation
- excellent assessment of bone (including marrow), cartilage, tendon, ligament, muscle - demonstrates bone marrow changes (not seen on x-ray, CT, USS) - can alignment of joints -multiplanar - expensive and time consuming - not all patients are suitable |
|
|
what is CPPD?
|
calcium pyrophosphate dihydrate crystal
causes CPPD disease - tendon calcification |
