Standard 135 degree reverse polyethylene insert combined with a neutral humeral stem in satisfactory coronal canal position


Picture
 The stem in neutral coronal canal position, the reverse standard polyethylene insert is medialized and overlapping the medial calcar

Picture
the humeral stem must be placed in the canal in a lateralized position to achieve neutral polyethylene position

Picture
- a medial stem and neutral polyethylene insert may
  1. increase medial COR,
  2. lateralize the stem;
  3. overstuff the joint
  4. tighter reduction
  5. medial calcar fracture
  6. increase deltoid wrap





The coronal position of the stem may not be controlled especially in stemless and short stemmed implants.  
​In the ' at risk' patient:

A high neck cut and varus stem may result in acromial stress fracture. 
A combined lateralized glenosphere and humerus may result in acromial stress fracture. 
A modular inlay stem may be helpful
