Klasifikasi Schatzker membagi fraktur tibia plateau menjadi enam tipe :
• Type 1:
lateral plateau fracture tanpa depresi
• Type 2:
lateral plateau fracture dengan depresi
• Type 3:
fraktur kompresi dari tibia plateau lateral
(A) atau central (B).
• Type 4:
fraktur medial plateau
• Type 5:
fraktur bicondylar plateau
• Type 6:
fraktur plateau dengan diskontinuitas
diafisis
Type I fracture
A type I fracture is a wedge-shaped pure cleavage fracture of the lateral tibial plateau, with a
displacement or depression less than 4mm. They are caused by the lateral femoral condyle being driven
into the articular surface of the tibial plateau.
Type II
Type II is a fracture with a combined cleavage and compression of the lateral tibial plateau, a type I
fracture with a depressed component. There is a depression greater than 4mm.
Type III fracture
A Schatzker type III fracture is a pure compression fracture of the lateral tibial plateau in which the
articular surface of the tibial plateau is depressed and driven into the lateral tibial metaphysis by
axial forces.
Type III fractures are divided into two subgroups: those with lateral depression (type IIIA) and those
with central depression (type IIIB).[3]
Type IV
Type IV is a medial tibial plateau fracture with a split or depressed component. These fractures occur
as a result of varus forces combined with axial loading in a hyperflexed knee. Type IV fractures have the
worst prognosis.[3]
TYPE V
Type VI
Type VI is a tibial plateau fracture with a dislocation of the metaphysis from the diaphysis. This
pattern results from high-energy trauma and diverse combinations of forces.[1] [3]
► Penatalaksanaan fraktur tipe I, II, dan III berpusat
pada evaluasi dan perbaikan kartilago artikular.
► Mekanisme fraktur-dislokasi fraktur tipe IV

Hemarthrosis
● Hemarthrosis is hemorrhage into a joint space and can be regarded as a
subtype of a joint effusion.
● Trauma is by far the most common cause of a hemarthrosis. Other
causes include bleeding disorders, anticoagulation, neurological deficits,
arthritis, tumors and vascular damage.

Patophysiology of hemarthrosis
Radiographic features
● Hemarthrosis displaces normal
structures, for example in an elbow,
anterior and posterior fat pads may
be elevated or visible
respectively. In the knee, there may
be anterior displacement of the
patella and quadriceps tendon. In
the shoulder, the humerus may be
inferiorly displaced, mimicking a
dislocation.
Hemarthrosis in a 40-year-old woman; standing lateral radiograph of the
right knee. Fluid density is present behind the patellar tendon and around
patella tip (arrows); note patella tilting (arrowhead) due to abundant
effusion.
Hemarthrosis and Lipohemarthrosis (illustrations)
Lipohemarthosis
results from an intra-articular fracture with escape of fat and blood from the bone
marrow into the joint, and is most frequently seen in the knee, associated with
a tibial plateau fracture or distal femoral fracture; rarely a patellar fracture. They
have also been described in hip, shoulder, elbow and wrist fractures

Lipohemarthrosis
Plain radiograph
The fat-fluid level is seen on any horizontal beam radiograph, such that the beam is tangential to
the fat-blood interface. In the knee this is best achieved with a cross-table horizontal lateral view,
where a long horizontal line is seen in the suprapatellar pouch. Ideally the patient has been lying
in that position for ~5 minutes to allow the fat and blood to adequately separate
In patients with a prominent suprapatellar plica, a double fat-fluid level may be seen
It is important to remember that up to 64% of tibial plateau fractures do not have an x-ray visible
lipohemarthrosis, but rather a simple hemarthrosis 1, thus absence of the finding does not exclude
an intra-articular fracture.
It is also important to remember that a simple hemarthrosis can separate into serum and red cells
(hematocrit effect) and create a subtle fluid-fluid level. This should not be mistaken for a
lipohemarthrosis 2. In some cases, all three layers can be seen, a so-called
lipohydrohaemathrosis. This tri-level appearance is sometimes known as parfait sign.

Lipohemarthrosis
CT and MRI
CT and MRI having much higher
sensitivity to density differences are not
only very sensitive at identifying intra-
articular fat, but also identify a hematocrit
effect, with three layers visible
(fat above, serum/synovial fluid middle,
red blood cells below)
The upper layer will follow fat on all
sequences and saturate on fat-saturated
sequences

Radiographic features
CT
◈ Another noninvasive technique is CTA, which utilizes intravenous contrast medium
injection to opacify the arterial lumen and detect any change in the caliber.
◈ Assessment of the stenosis, occlusion and collateral circulation can be done using
multislice thin axial cuts followed by multiplanar reconstruction. Maximum intensity
projections (MIP) and volume rendering techniques (VRT) can also be used in the
assessment of the vessels.

CTA of Lower Extremities Protocol
▪ The patient is placed feet first and supine on the scanner table, with feet and
ankle joints in neutral position.
▪ The typical field-of-view (FOV) extends from the lower thorax (diaphragm) to
the toes, with an average scan length of 110–130 cm.
▪ A scanning protocol for peripheral CTA should always include (1) a scout
image, (2) a test bolus or bolus triggering acquisition (based on the operator’s
preference), and (3) CTA acquisition during the arterial contrast phase.
▪ A second late CTA acquisition of the distal territories may be prescribed in case
of inadequate pedal opacification during the arterial CTA.
▪ An entire peripheral CTA study may be easily performed in 10–15 minutes.
Contrast Injection
◈ Intravenous contrast medium is injected by using a power injection into an
antecubital vein (20–22 gauge cannula).
◈ The time the contrast takes to travel from the injection site to the aorta (transit
time) is variable between patients.
◈ In addition, the transit time of intravenous contrast agents traveling from the aorta
to the popliteal artery has also been shown to vary significantly between patients
in relation to the severity of atherosclerotic disease.
◈ Empirically, a contrast bolus length of at least 30 s should be used to enable all
patients to be imaged.
Contrast Injection
◈ When the bolus chase technique is employed, 100–120 ml of contrast (with an
iodine concentration between 320 and 370 mg/ml) are administered at a rate of 4
ml/s.
◈ When an automated bolus detection algorithm is used, the region of interest is set
up in the aorta immediately below the level of the diaphragm.
◈ A repetitive monitor acquisition (120kV, 10 mAs, 1 s interscan delay) is started 10
s after contrast injection begins.
◈ The actual peripheral CTA acquisition is then started when the contrast
enhancement reaches a prespecified level (typically set between 150 and 200
Hounsfield units (HU).
◈ In general, the use of 370 mg/ml contrast agents yields excellent results.

  • 20. Klasifikasi Schatzker membagi fraktur tibia plateau menjadi enam tipe : • Type 1: lateral plateau fracture tanpa depresi • Type 2: lateral plateau fracture dengan depresi • Type 3: fraktur kompresi dari tibia plateau lateral (A) atau central (B). • Type 4: fraktur medial plateau • Type 5: fraktur bicondylar plateau • Type 6: fraktur plateau dengan diskontinuitas diafisis
  • 21. Type I fracture A type I fracture is a wedge-shaped pure cleavage fracture of the lateral tibial plateau, with a displacement or depression less than 4mm. They are caused by the lateral femoral condyle being driven into the articular surface of the tibial plateau.
  • 22. Type II Type II is a fracture with a combined cleavage and compression of the lateral tibial plateau, a type I fracture with a depressed component. There is a depression greater than 4mm.
  • 23. Type III fracture A Schatzker type III fracture is a pure compression fracture of the lateral tibial plateau in which the articular surface of the tibial plateau is depressed and driven into the lateral tibial metaphysis by axial forces. Type III fractures are divided into two subgroups: those with lateral depression (type IIIA) and those with central depression (type IIIB).[3]
  • 24. Type IV Type IV is a medial tibial plateau fracture with a split or depressed component. These fractures occur as a result of varus forces combined with axial loading in a hyperflexed knee. Type IV fractures have the worst prognosis.[3]
  • 26. Type VI Type VI is a tibial plateau fracture with a dislocation of the metaphysis from the diaphysis. This pattern results from high-energy trauma and diverse combinations of forces.[1] [3]

  • 29. Hemarthrosis ● Hemarthrosis is hemorrhage into a joint space and can be regarded as a subtype of a joint effusion. ● Trauma is by far the most common cause of a hemarthrosis. Other causes include bleeding disorders, anticoagulation, neurological deficits, arthritis, tumors and vascular damage.
  • 31. Radiographic features ● Hemarthrosis displaces normal structures, for example in an elbow, anterior and posterior fat pads may be elevated or visible respectively. In the knee, there may be anterior displacement of the patella and quadriceps tendon. In the shoulder, the humerus may be inferiorly displaced, mimicking a dislocation. Hemarthrosis in a 40-year-old woman; standing lateral radiograph of the right knee. Fluid density is present behind the patellar tendon and around patella tip (arrows); note patella tilting (arrowhead) due to abundant effusion.
  • 33. Lipohemarthosis results from an intra-articular fracture with escape of fat and blood from the bone marrow into the joint, and is most frequently seen in the knee, associated with a tibial plateau fracture or distal femoral fracture; rarely a patellar fracture. They have also been described in hip, shoulder, elbow and wrist fractures
  • 34. 4 2 Lipohemarthrosis Plain radiograph The fat-fluid level is seen on any horizontal beam radiograph, such that the beam is tangential to the fat-blood interface. In the knee this is best achieved with a cross-table horizontal lateral view, where a long horizontal line is seen in the suprapatellar pouch. Ideally the patient has been lying in that position for ~5 minutes to allow the fat and blood to adequately separate In patients with a prominent suprapatellar plica, a double fat-fluid level may be seen It is important to remember that up to 64% of tibial plateau fractures do not have an x-ray visible lipohemarthrosis, but rather a simple hemarthrosis 1, thus absence of the finding does not exclude an intra-articular fracture. It is also important to remember that a simple hemarthrosis can separate into serum and red cells (hematocrit effect) and create a subtle fluid-fluid level. This should not be mistaken for a lipohemarthrosis 2. In some cases, all three layers can be seen, a so-called lipohydrohaemathrosis. This tri-level appearance is sometimes known as parfait sign.
  • 35. 4 3 Lipohemarthrosis CT and MRI CT and MRI having much higher sensitivity to density differences are not only very sensitive at identifying intra- articular fat, but also identify a hematocrit effect, with three layers visible (fat above, serum/synovial fluid middle, red blood cells below) The upper layer will follow fat on all sequences and saturate on fat-saturated sequences

  • 42. Radiographic features CT ◈ Another noninvasive technique is CTA, which utilizes intravenous contrast medium injection to opacify the arterial lumen and detect any change in the caliber. ◈ Assessment of the stenosis, occlusion and collateral circulation can be done using multislice thin axial cuts followed by multiplanar reconstruction. Maximum intensity projections (MIP) and volume rendering techniques (VRT) can also be used in the assessment of the vessels. 51
  • 45. CTA of Lower Extremities Protocol ▪ The patient is placed feet first and supine on the scanner table, with feet and ankle joints in neutral position. ▪ The typical field-of-view (FOV) extends from the lower thorax (diaphragm) to the toes, with an average scan length of 110–130 cm. ▪ A scanning protocol for peripheral CTA should always include (1) a scout image, (2) a test bolus or bolus triggering acquisition (based on the operator’s preference), and (3) CTA acquisition during the arterial contrast phase. ▪ A second late CTA acquisition of the distal territories may be prescribed in case of inadequate pedal opacification during the arterial CTA. ▪ An entire peripheral CTA study may be easily performed in 10–15 minutes.
  • 46. Contrast Injection ◈ Intravenous contrast medium is injected by using a power injection into an antecubital vein (20–22 gauge cannula). ◈ The time the contrast takes to travel from the injection site to the aorta (transit time) is variable between patients. ◈ In addition, the transit time of intravenous contrast agents traveling from the aorta to the popliteal artery has also been shown to vary significantly between patients in relation to the severity of atherosclerotic disease. ◈ Empirically, a contrast bolus length of at least 30 s should be used to enable all patients to be imaged.
  • 47. Contrast Injection ◈ When the bolus chase technique is employed, 100–120 ml of contrast (with an iodine concentration between 320 and 370 mg/ml) are administered at a rate of 4 ml/s. ◈ When an automated bolus detection algorithm is used, the region of interest is set up in the aorta immediately below the level of the diaphragm. ◈ A repetitive monitor acquisition (120kV, 10 mAs, 1 s interscan delay) is started 10 s after contrast injection begins. ◈ The actual peripheral CTA acquisition is then started when the contrast enhancement reaches a prespecified level (typically set between 150 and 200 Hounsfield units (HU). ◈ In general, the use of 370 mg/ml contrast agents yields excellent results.
