- 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,
FCR,
PL, &
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,
its 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;
