• Fig B 34-1 Ischial tuberosity. Bilateral chronic avulsions. Note the protuberant bone (closed arrows) and a large, smooth fragment (open arrows).43
• Fig B 34-5 Lesser trochanter (solid arrow). A lytic defect representing metastatic cancer is seen at the femur attachment site (open arrow).43
• Fig B 34-10 Posterior cruciate ligament. (A) Axial CT shows minimal displacement of the avulsed fragment (arrows). (B) Sagittal proton-density-weighted MR image shows displacement of an avulsed fragment (arrow).43
• Fig B 34-11 Tibial tuberosity. There is displacement of the proximal base of the epiphysis and extension into the joint (arrows).43
• Fig B 34-12 Inferior pole of the patella (white arrowhead). The black arrowhead points to the site of the avulsion from the abnormally high patella.44
• Fig B 34-14 Posterior capsule. Curvilinear calcification adjacent to the posterior tibial margin (arrow).43
Fig B 34-15 Anterior capsule. Protuberance of the anterior talus (arrow) where the joint capsule is inserted, indicating a chronic avulsion.43
• Fig B 34-16 Greater tuberosity. (A) Frontal radiograph shows the nondisplaced avulsion (arrows). (B) Coronal oblique T1-weighted MR image shows the fracture to greater advantage (arrow).43
