Steindler Flexorplasty

- Theory:
    - flexor-pronator muscles arising from medial epicondyle are transposed to more proximal point on the humerus so that their moment for
         elbow flexion is incresed enough to permit active control;
    - muscles originating from the medial epicondyle (Pronator Teres, FCRPL, & FCU) must have normal or near normal power to achieve a
         useful result from flexorplasty;
    - although most patients can flex thru a useful range against gravity, it's rare for pts to be able to lift > 5 pds following transfer;
- Exam:
    - pts who already have weak elbow flexion are most likely to have satisfactory results;
    - ask pt to flex forearm after flexing wrist & fingers & pronating forearm
