– See: Total Hip Replacement Menu – Discussion:     – design considerations      – femoral stem collar     – cemented femoral stems (radiology of cemented femoral stems)      – press fit femoral stems      – femoral component offset             – modular neck:                    – … Read more

Femoral Component Offset:

– Discussion:     – see acetabular component, reestablishment of acetabular floor, and component position;     – see: preoperative and post operative radiographic eval     – femoral offset is measured from the distance between the center of the femoral head and a line drawn down center of femoral shaft;     – note that increasing … Read more

Femoral IM Nail Entry Point

      – Discussion:     – two sites have been proposed for nail entry:     – tip of the greater trochanter and the piriformis fossa; – Entry thru Piriformis Fossa;      – main advantage a colinear trajectory with the long axis of the femoral shaft      – accurate positioning of the entrace hole is critical.      … Read more

– See:       – Zone I injuries       – Zone II injuries       – Zone III injuries       – Zone IV and Zone V: – Discussion:      – FDS serves as an isolated activator of middle phalanx;      – function is determined by holding adjacent … Read more

Fat Pads

– Discussion:     – two fat planes on lateral view & 5 fat planes on PA view are useful for analysis;     – deep fat pad of pronator quadratus (lateral view), which lies between the pronator quadratus muscle and the flexor tendon sheaths, normally forms a slight ventral concave line and is convexly bowed in a ventral … Read more

FDP Avulsion/Rupture

    – See: Phalangeal Injury – Mechanism: – results from forceful hyperextension of DIP joint w/ FDP in maximal contraction; – classic examples include pts injured by the sudden jerk of a rope, such as starting a lawnmower or retraining an animal; – tendon may rupture directly from its insertion into bone, or it … Read more
