摘要： The present disclosure relates to an anatomical locking guide steel plate for a complicated acetabulum fracture, an anatomical locking guide apparatus and matched guide sleeve apparatus. The inner side of said anatomical locking guide steel plate contacts with a face of the acetabulum, said anatomical locking guide steel plate includes three portions, a head of the steel plate, a body of the steel plate and a tail of the steel plate, said head of the steel plate, said body of the steel plate and said tail of the steel plate are jointed seamlessly. Using the steel plate provided by the present disclosure can reposition and fix the complicated acetabulum fracture efficiently. It can avoid shaping the steel plate in the surgery, so the operative time may be shortened, and the difficulty of the surgery may be lower. The surgical trauma is small, and the surgical bleeding is slight.

摘要： The present invention relates to a wing-shaped angle steel plate and a bone shaft fixation system. The wing-shaped angle steel plate comprises a wing fitting portion and a body fixation portion which are fixedly connected to each other. The wing fitting portion is used for supporting a fracture end and has a structure matched with an inner side surface of a bone shaft. The body fixation portion is used for fixing the wing fitting portion and has a structure matched with a front side of the bone shaft. The body fixation portion is provided with at least two first locking holes for passing through first locking screws at an intersection site with the wing fitting portion and is further provided with at least two second locking holes for passing through second locking screws in the structure matched with the front side of the bone shaft. In the wing-shaped angle steel plate, the wing fitting portion and the body fixation portion of the present invention are connected to each other and cooperate to fix and support the bone shaft fracture end site, and effectively ensure and help stable reduction and healing of the fracture sites.

摘要： A medial buttress construct and a fracture fixation device for femoral neck are disclosed. The medial buttress construct for femoral neck comprises a support part and an attachment fixing part fixedly connected to each other. The support part includes a structure matching an inferior surface of a proximal end of the femoral neck. The attachment fixing part includes structures simultaneously matching a front side surface of a distal end of the femoral neck and a front side surface of an upper end of femoral shaft. The attachment fixing part includes at least one opening for allowing a screw to pass through the structure matching the front side surface of the distal end of the femoral neck, and at least one opening for allowing a screw to pass through the structure matching the front side surface of the upper end of the femoral shaft.
