AI Technical Summary
Current acromioclavicular joint dislocation surgeries suffer from problems such as large incisions, difficulty in achieving a double-locking state, and the floating of two titanium plates. In particular, clavicle hook plate surgery is prone to causing intra-articular damage, and locking loop titanium plate treatment carries the risk of adjustable loop loosening and insufficient tightening.
Design an assembly comprising a threaded titanium plate, a supporting titanium plate, and a loop member. The threaded titanium plate is mounted on the clavicle via a column portion. The loop member forms a double-locked state on the outer circumference of the titanium plate via a knotted head and a wire end, preventing the titanium plate from floating. The wiring of the loop member is hidden within the titanium plate body or groove.
This approach reduces the incision size, ensures a double-locking state, improves the stability of surgical healing, avoids titanium plate floating and abnormal protrusions, and enhances the stability and safety of the surgery.
