The invention relates to the technical field of orthopedic biomedical treatment, in particular to a
proximal humerus fracture intramedullary
bone cement supporting rod. The
bone fracture plate comprises a
bone fracture plate body, a plurality of first connecting holes and a plurality of second connecting holes are formed in one side of the
bone fracture plate body in a penetrating mode, and
solid bone nails are arranged in the first connecting holes. According to the device,
bone cement is injected into a marrow cavity from an injection molding channel and an injection molding opening and then solidified into a rod body, the marrow cavity space is tightly filled, supporting structures are synchronously formed on the inner side and the outer side of the
humerus through cooperation of a bone fracture plate and a
bone cement supporting rod in the marrow cavity space, and therefore stress generated when arms of a patient move is evenly dispersed on the two sides of the
humerus; the fixing stability is remarkably improved, the risk of
internal fixation failure such as steel plate displacement and screw
cutting is effectively reduced, and the bone
cement supporting rods can further prevent displacement of fracture blocks, promote fracture repair, relieve
extrusion and friction of surrounding tissue of a filling position, reduce
inflammatory response and
postoperative pain and improve the
rehabilitation comfort of a patient.
