Changes in Tip-Apex Distance by Position and Film Distance Measured by Picture Archiving and Communication System (PACS).

Purpose: The tip-apex distance (TAD) is used to predict the clinical outcome of intertrochanteric fracture fixation. We aimed to measure the changes in TAD by position and film distance using Picture Archiving and Communication System (PACS).

Materials And Methods: We used a femur replica with a 10° femoral neck anteversion and a 130° neck shaft angle.

Adenomyoepithelioma located over the tibial tuberosity.

Adenomyoepithelioma is a rarely occurring tumor and its generation in the limbs is extremely rare. We report a case of an adenomyoepithelioma over the proximal tibial tuberosity that was treated without any complications after an excisional biopsy with a literature review.
