Acetabulum:
- top of the acetabulum is made up of os ilium - is made up of body of the three pelvic bones - os pubis makes up half of the acetabular cup - in childhood it is made up of os ilium and ischii only |
Acetabulum:
- top of the acetabulum is made up of os ilium+ - is made up of body of the three pelvic bones+ |
|
Lunate surface of the acetabulum:
- is covered with articular cartilage - is much thicker in cranial part - pulvinar of the acetabulum is situated around lunate surface - articular cartilage is much thicker in distal part |
Lunate surface of the acetabulum:
- is covered with articular cartilage+ - is much thicker in cranial part+ |
|
Position of the acetabulum:
- directs externally, down and forward - inclination of the acetabulum is approximately 45 degrees - acetabular cup and frontal plane form the right angle in childhood - anteversion of the acetabulum cup is more than 70 degrees |
Position of the acetabulum:
- directs externally, down and forward+ - inclination of the acetabulum is approximately 45 degrees+ |
|
X-ray examination of the acetabular fractures:
- Letournel’s projection complement classical AP view - affected side is displaced from the ground by obturator oblique view - Letournel’s projection includes „inlet and outlet view“ - AP projectionis performed in 90 degrees flection in hip joint |
X-ray examination of the acetabular fractures:
- Letournel’s projection complement classical AP view+ - affected side is displaced from the ground by obturator oblique view+ |
|
Posterior column of the acetabulum:
- is easily evaluated by the iliac projection - is more massive than anterior column - its X-ray view is not important for diagnosis of acetabular fractures - treatment of its fracture is only conservative |
Posterior column of the acetabulum:
- is easily evaluated by the iliac projection+ - is more massive than anterior column+ |
|
Letournel’s classification:
- divides fractures of the acetabulum in simple and combined - fractures of both column are among simple fractures - fracture of the posterior wall is rarer than fracture of the anterior wall - T-fractures are example of combined fractures |
Letournel’s classification:
- divides fractures of the acetabulum in simple and combined+ - T-fractures are example of combined fractures+ |
|
Treatment after osteosynthesis of acetabular fractures:
- early verticalization with minimalization the weight on the affected extremity - after plating fixation is possible full weighting on the affected extremity - early verticalization is prevention of thromboembolic disease - six weeks in bed is always required |
Treatment after osteosynthesis of acetabular fractures:
- early verticalization with minimalization the weight on the affected extremity+ - early verticalization is prevention of thromboembolic disease+ |
|
Consequences after acetabular fractures:
- higher risk of earlier arthritis - no enhanced risk of aseptic necrosis of femoral head - late problems are possible to solve by total hip replacement - no arthritis after osteosynthesis of acetabular fractures |
Consequences after acetabular fractures:
- higher risk of earlier arthritis+ - late problems are possible to solve by total hip replacement+ |
|
Central dislocation of acetabular fracture:
- there is no injury of the sciatic nerve - has a poor prognosis - accompanied by retroperitoneum bleeding - never requires a total hip replacement |
Central dislocation of acetabular fracture:
- has a poor prognosis+ - accompanied by retroperitoneum bleeding + |
|
Fracture of posterior wall of the acetabulum:
- the most frequent type of acetabular fracture - we mostly choose surgically way of treatment - never injured articular surface of the acetabulum - we mostly choose conservative way of treatment |
Fracture of posterior wall of the acetabulum:
- the most frequent type of acetabular fracture+ - we mostly choose surgically way of treatment+ |
|
Osteosynthesis of acetabular fractures is made:
- by using various types of plates - by using lags crews - by using absorbable material - only by using of transfixation with Kirschner´s wires |
Osteosynthesis of acetabular fractures is made:
- by using various types of plates+ - by using lags crews+ |
|
Injury of sciatic nerve is caused:
- by iatrogenic injury in posterior surgical approach - by current fracture of upper part of pubic bone - by dislocation of fragments of posterior column - no injury of the sciatic nerve occurs in acetabular fractures |
Injury of sciatic nerve is caused:
- by iatrogenic injury in posterior surgical approach+ - by dislocation of fragments of posterior column+ |
|
X-ray examination of posterior wall of the acetabulum:
- patient lies on the unaffected side of the body - CT examination is indicated - dislocation of femoral head in fracture of posterior wall can be seen only on CT - X-ray of pelvis is necessary to make |
X-ray examination of posterior wall of the acetabulum:
- CT examination is indicated+ - X-ray of pelvis is necessary to make+ |
|
Fracture of posterior column of the acetabulum:
- relatively rare - usually connected with hip dislocation dorsally - vasa glutea superiora cannot be affected - after reposition of femoral head is not necessary fixation of posterior column |
Fracture of posterior column of the acetabulum:
- relatively rare+ - usually connected with hip dislocation dorsally+ |
|
Fractures of anterior wall of the acetabulum:
- rarer than fracture of posterior wall - the same frequency as fracture of posterior wall - occurs in older patients with osteoporosis - always rises as high-energy trauma |
Fractures of anterior wall of the acetabulum:
- rarer than fracture of posterior wall+ - occurs in older patients with osteoporosis+ |
