New description: [New technical field] This creation is about a femoral head and neck strengthening device, especially a segmental combination of femoral head and neck strengthening device for strengthening femoral head support and femoral neck fracture Fixed or intertrochanteric fracture fixation. [Prior Art] The cause of Avascuiar Necrosis of Femeral Head can be roughly divided into post-traumatic or non-traumatic causes. The former may be due to femoral neck fracture and hip dislocation. The injury causes damage to the blood vessels that are delivered to the femoral head, which in turn causes avascular necrosis of the femoral head. The latter may cause avascular necrosis of the femoral head due to alcohol consumption, smoking, excessive work and steroid use. The degree of avascular necrosis of the femoral head can be divided into six stages: 1 · Another · The patient feels pain, but the X-ray is normal, and necrosis must be seen by (nuclear magnetic resonance imaging). This stage can be controlled by medication. 2. Phase 2: The cystic changes of the femoral head can be seen and core decompression is required. 3. Stage 2: The subchondral bone of the femoral head collapses, but the femoral head does not flatten. 4. Stage 4: The femoral head is obviously collapsed and flattened, and a half-hip artificial exchange is required. 5: Stage 5: The hip joint is degraded and narrowed. 6· & ¥ and /, · The pelvic body structure has been destroyed, the entire lens joint produces severe degenerative lesions, stage 5, 6 need to perform total hip arthroplasty. Strict femoral head necrosis stage II~3' Even if the core decompression M287665 does not prevent the femoral head from collapsing, other artificial instruments should be implanted in this case, so the appropriate femoral head reinforcement structure is needs. Furthermore, if the elderly may have simultaneous avascular necrosis of the femoral head and proximal femoral fracture due to fragility of the bone, as shown in Figure 9, when the femoral (91) intertrochanteric fracture occurs, the dynamic femoral screw (Dynamic) Hip Screw, DHS) fixes the fracture, which consists of a bone plate (92), a screw (93) that passes through the bone plate (92) and is implanted from the outside of the femur (91) into the femoral head (911). A bone screw (94) for fixing the bone plate (92) to the outside of the femur (91) has the advantages of small surgical wound and short operation time. However, if the patient has only avascular necrosis of the femoral head, the use of this conventional structure to strengthen the support of the femoral head will result in waste of material and surgical time due to excess parts. Therefore, the creators of this case have accumulated experience in designing and manufacturing over the years. After continuous thinking and revision, they are required to provide a femoral head and neck strengthening device that can respectively treat avascular necrosis of the femoral head and proximal femoral fracture.
