Anterior Inferior Iliac Spine Avulsion (AIIS) A Femoral Neck Stress Fracture (FNSF) is caused by repetitive loading of the femoral neck that leads to either compression side (inferior-medial neck) or tension side (superior-lateral neck) stress fractures.

Skeletal survey, chest CT, and referral to an orthopaedic oncologist for biopsy, Hip abduction brace immobilization with the hip in 45 degrees of flexion and neutral rotation for 6 weeks, Protected weight bearing and activity as tolerated, Immobilize in 120 degrees of knee flexion for 24 hours followed by physical therapy. WebAnterior Inferior Iliac Spine Avulsion (AIIS) A Femoral Neck Stress Fracture (FNSF) is caused by repetitive loading of the femoral neck that leads to either compression side (inferior-medial neck) or tension side (superior-lateral neck) stress fractures. WebAnterior cruciate ligament (ACL) avulsion fracture or tibial eminence avulsion fracture is a type of avulsion fracture of the knee. At closer look you will notice that the horizontal structure has a lower signal intensity than the meniscus and looks funny. Femoral neck fracture. On the left three consecutive coronal PD-images: A Segond fracture is almost pathognomonic for an anterior cruciate ligament tear, which was also demonstrated in this patient. The intercondylar "notch" view is very helpful. Back and Neck Pain. The double posterior cruciate ligament (PCL) sign is a low-signal-intensity band that is parallel and anteroinferior to the PCL on sagittal MR images. The outside one-third of the meniscus is called the 'red' zone, because it has a rich blood supply. Multiple reports indicate OBJ is looking at a mid-November return placing him at 9 months post-op.
