Knee MRI 썸네일형 리스트형 [Case_Adv] Accessory Iliotibial Band-Meniscal Ligament, normal variant, lateral meniscus https://youtu.be/wmpIaimU2gE The anatomic variation of the anterolateral fixation of the lateral meniscus to the ITB, which we have termed the “accessory iliotibial band–meniscal ligament” or “AIML.” An AIML was present in 13.3% of all patients (136/1019). AJR Am J Roentgenol. 2019 Oct;213(4):912-917. Although the attachments of the anterior and posterior horn are relatively consistent, the ante.. 더보기 [Knee-04] Anatomy of layers and components, Posterolateral corner 01 https://youtu.be/lMx9cjkzNZw Three structural layers Layer 1:most superficial Fascia lata lliotibial tract with its anterior expansion Superficial portion of biceps femoris with its posterior expansion Layer 2 Quadriceps retinaculum anteriorly Two patellofemoral ligaments or retinacula posteriorly Lavers 1 and 2 merges at lateral aspect of the patella Layer 3:deepest layer The lateral joint .. 더보기 [Knee-03] Tear of Popliteus tendon, Posterolateral corner (PLC) injury https://youtu.be/XVRwYJa4f2M 1.

Popliteus musculotendinous complex, popliteomeniscal fascicle, popliteal bursa, cyamella With popliteus tears, it is important to note - the site of the tear (intra- articular or extra-articular), - the extent of tear (partial or full-thickness), - the presence of a bone fragment if there has been tendon avulsion - degree of tendon retraction Partial-thickness tear of the popliteus tendon, High-grade partial tearing of the PT at its femoral insertion Most popliteus tears are extra-a.. 더보기 [Knee_Case_#03] [Typical case] Flap tear of the meniscus, Changing slope sign, The nondisplaced component of a flap tear may demonstrate a changing slope contour of its superior surface. Criteria for diagnosis of a flap tear based on sagittal images include: * A vertical tear encompassing the inner third of the meniscus,either coapted or noncoapted * Relative deficiency of the inner third of the inferior meniscal surface with associated blunting of the remaining inferior l.. 더보기 [Knee_Case_#02] pullout fixation for avulsion fractures of the PCL from the tibia Treatment of avulsion fractures of the PCL depends on the degree of avulsion fracture displacement. Conservative therapy is generally performed if the degree of avulsion fracture displacement is mild, whereas surgery is performed in patients with significant displacement and posterior tibial instability. In the past, internal fixation was highly invasive, requiring a marked opening of the back o.. 더보기 이전 1 2 3 4 ··· 11 다음
