Benefits of technology
The technical effect described this patented technology relates to an improved method or device used during orthopedic procedures such as internal joint fusion surgery (IJF). This new technique involves fixing broken ends together inside a patient's body without damaging them from previous surgeries. It also includes injecting bone-cement into small spaces called osteocysts made up of tiny calcium hydroxyapatite crystals filled with liquid plaster material. These techniques help stabilizing these structures more reliably and improve their overall function over time.
Problems solved by technology
This technical problem addressed by this patented technology relates to improving the fixing and reducing complications associated with intra-ossilocal fractured hip (IFO) due to its potential use during orthopedic surgeries like fusion procedures. Current methods involve invasive open procedure approaches involving multiple steps including drilling hole(s), inserting screw bolts, applying external fixators, etc., leading to increased risks from accidentally damaging surrounding tissues and potentially requiring revision operations. There is currently no effective solution available yet without increasing operational complexity while maintaining stable fixations within the affected area.

The invention relates to an internal fixation repair system for femoral intertrochanteric fracture. A head sleeve is fixed between femoral intertrochanteric, a bone cement screw is arranged on a head raised sleeve, a balloon dilatation instrument is arranged along a central hole of the bone cement screw, and a cavity is expanded inside the femoral head; after the balloon dilatation instrument is withdrawn, a bone cement injector is placed in along a central hole of the bone cement screw, bone cement is injected into a cavity in the femoral head, after the steel plate part is rotated to be attached to the femoral shaft, the bone cement screw is locked in a head protruding sleeve, a first locking screw is locked in a head thread, and the tip end of the thread is placed in the bone cement; cortical bone compression screws and short locking screws are installed, finally, the whole steel plate is completely fixed between femoral trochanters, the two screws at the head are used for fixing the intertrochanteric fracture, meanwhile, the fracture end is prevented from rotating, the axial compression and stability of the fracture end are improved, and the crushed fracture blocks are effectively fixed; steel plate loosening and fracture block displacement are effectively avoided; the internal fixation repair system is simple in structure and it is convenient for doctors to operate the internal fixation repair system.
