Description

Technical Field

[0001] The utility model relates to the technical field of femoral neck fracture prevention, in particular to a protective brace for femoral neck fracture prevention. Background Technique

[0002] The femoral neck is located within the hip joint and is the part connecting the femoral head and the greater trochanter (femoral tuberosity) of the femur. The femoral neck is relatively slender compared to other parts, is the main supporting structure of the femoral head, and is also a stress concentration area, so it is prone to fracture. Such fractures are mostly caused by accidentally falling while walking and landing on the buttocks. After the injury, the hip is painful and the patient cannot stand or walk. Femoral neck fracture is one of the common fracture types in the elderly, mostly due to reasons such as osteoporosis and degeneration of hip muscle groups.

[0003] Therefore, for the middle-aged and elderly population, it is extremely necessary to protect against femoral neck fractures. Usually, although taking vitamin D can strengthen bone mass, certain protection is still required to ensure the walking stability of the elderly population. However, the existing braces are inconvenient to adjust and cannot adjust the position of the brace according to the patient's body size.

[0004] For this reason, we propose a protective brace for femoral neck fracture prevention. Content of the Utility Model
