Straight Intramedullary Nail Technique for Proximal Humerus Fractures
No.1 Design Concept of Straight Intramedullary Nail
The design of the straight (third generation) intramedullary nail allows insertion at the highest point of the humeral head, through the supraspinatus belly, but avoids the supraspinatus tendon, thereby avoiding injury to the rotator cuff (pictured below).
No.2 Closed or minimally invasive fixation under fluoroscopy
Operation: closed reduction, the guide pin is drilled from the highest point of the humeral head, and the optimal position is determined by fluoroscopy; the hollow drill is drilled, the intramedullary nail is inserted, and if the position is satisfactory, the proximal and distal locking are performed; "Reinforced stitching.
No.3 Correction of reduction by intramedullary nailing
The distal end is preferentially locked, and then residual malalignment is corrected by traction internal rotation or external selection.
No.4 Fracture end compression
After the distal end is preferentially locked, the fracture end is compressed by the return stroke of the sliding hammer.
No.5 Clinical effect
Imaging examination showed that the fracture was basically healed 3 months after the operation; the function was good.
