The distal humeral Locking Plate series can be divided into distal lateral locking plate, distal medial locking plate and distal Y-shaped plate.
Advantages
(1) The Orthopeadic Plate shape is consistent with the anatomical shape of the distal humerus, with good adhesion and less stimulation to soft tissues. There is no need for pre bending during surgery, which is beneficial for reducing the workload of surgeons.
(2) Using 2.7mm or 3.5mm orthopedic screws is beneficial for fixing small fracture fragments.
(3) The design of the posterior lateral and central plates adapts to different forms of fractures, increasing stability.
(4) The combination design of pressure hole and locking hole provides more fixation options.
(5) The use of 2.7mm or 3.5mm surgery screws in combination provides good locking ability and support for bone fracture in distal humerus and other areas.
(6) According to the surgical requirements, the internal and external humeral Locking Plates can be combined for fixation, ensuring safety and stability.
Surgical steps for AO fixation of distal humerus
1. When resetting, first fix the pulley and use hollow screws.
2. Then use a Kirschner wire to fix the fracture block through a steel plate, making sure that the steel plate wraps around the distal end slightly.
3. First, use ordinary screws to fix the hole at the proximal end of the humerus, completing temporary fixation without tightening it too tightly.
4. Then perform unilateral compression fixation at the distal end.
5. Use large tissue forceps and compression screws to complete the compression fixation between the condyles.
6. Use the same method to secure the opposite side.
7. Finally, complete the locking of other screws to form a complete mechanical structure of the distal humerus. Try to fill the distal screws as much as possible to complete the intercondylar connection, and have at least 3 screws in the proximal end. Long screws (diagonal screws) must be connected between the condyles.
