The proximal humeral compression Locking Plate expands the surgical indications for open reduction and internal fixation in the treatment of proximal humeral fractures.
It can effectively neutralize various abnormal stresses, provide sufficient stability even if the fracture site is poorly boned, and will not further damage the blood supply to the humeral head. Three part fractures with poor bone quality in the elderly and compression type four part fractures can also be included as surgical indications for open reduction and internal fixation treatment.
fracture surgery through the deltoid approach is not only safe but also comfortable, reducing the risk of axillary nerve injury. Suture traction is performed on the rotator cuff tendon to assist in rotating the proximal humerus, facilitating the placement of the steel plate behind the biceps tendon groove
Due to the fact that Locking Plates cannot assist in reducing fractures like compression plates, doctors need to adopt techniques suitable for the type of fracture for reduction when using locking plates. The methods mainly include lever (two part inversion compression fracture), corrected rotation (three part fracture), and prying and lifting (four part compression fracture).
With the aging of the social population, the incidence rate of proximal humeral fractures in the elderly is on the rise, becoming the most common upper arm osteoporotic fractures; Fracture looseness and falls are also the main reasons for the high incidence rate of proximal humeral fractures in the elderly. Most non displaced stable proximal humeral fractures can be treated conservatively, but displaced fractures often require open reduction and internal fixation.
The trend in the treatment of proximal humeral fractures is to use proximal humeral locking plates, which have the advantages of stable angles, cross insertion of locking screws into the humeral head, strong resistance to extraction, good long-term fracture reduction and maintenance after surgery, and minimal internal fixation failure. Osteoporosis of the humeral head is an important influencing factor for internal fixation failure. Osteoporosis of the humeral head can lead to a hollow shell shape of the humeral head, causing the screws inside the humeral head to be unable to hold the humeral head, resulting in postoperative loss of reduction. In the long term, it can lead to the failure of screw extraction and internal fixation.
