For unimpacted surgical neck fractures generally, the most appropriate reduction technique will depend upon the fracture morphology.
Medial hinge intact:
Fix plate to the humeral head and use it as reduction aid
Reduce and fix the shaft to the plate
After reduction, both, the sagittal and the coronal plane should be correct. Particular attention should be paid to the correct rotation.
Particularly with comminuted surgical neck fractures, remember that rotator cuff sutures can help reduce the humeral head against the plate to restore normal alignment.
Choose whichever approach is best suited for anticipated reduction maneuvers. The deltopectoral approach, while more extensile, is more invasive, but may provide easier access to a longer plate.
Correct plate position
A correct plate position must be ensured in order to avoid loss of reduction and impingement.
Angular stable versus standard plates
This procedure describes proximal humeral fracture fixation with an angular stable plate (A). Sometimes, these implants are not available. Standard plates provide an alternative option, for example the modified cloverleaf plate (B). Presently, the specific indications, advantages, and disadvantages of angular stable and standard plates are being clarified. There is some evidence that angular stable plates provide better outcomes. In addition to type and technique of fixation, the quality of reduction, the soft-tissue
handling, and the characteristics of the injury and patient significantly influence the results. There is no evidence that the use of angular stable plates will overcome these other factors.
