Only healthy individuals with sufficient arm and finger strength to handle the belt's elasticity can pull the end of the belt from the anterior superior iliac spine to the greater trochanter of the femur with both hands and then secure it with hook-and-loop fasteners to support the pelvis. Therefore, providing a pelvic belt that can be easily attached with one hand is a challenge. [Solution] The pelvic support belt is characterized by comprising a metal or resin square ring 1 positioned at one end of the pelvic support belt, a metal or resin tube 2 positioned to surround the long side of the metal or resin square ring 1, a main belt 3, ventilation holes 4 provided in the main belt 3, a permanent fastening hook-and-loop fastener 5 positioned on the central flat part of the main belt 3, temporary fastening hook-and-loop fasteners 6 and 7 positioned on the side of the pelvic support belt opposite to the metal or resin square ring 1, and a hook-and-loop fastener 8 positioned at the end of the pelvic support belt opposite to the metal or resin square ring 1.

A reverse bolted greater trochanter periprosthetic plate configured to be mounted to a femur of a patient includes a central portion with an inner surface configured to face and / or contact a femoral surface of the femur; a plurality of leg portions extending from the central portion forming a claw configured to grasp a portion of the femur; and a bolt receptor portion extending from the central portion configured for receiving a bolt for securing the plate to the femur during a reverse bolted greater trochanter periprosthetic procedure.

FIELD: traumatology; orthopedics.SUBSTANCE: used for arthroscopy of the hip joint to eliminate Cam or combined types of femoroacetabular impingement. A proximal anterolateral port is created to the peripheral portion of the hip joint, which is used as a viewing port at the beginning of the operation; 4 cm distal and 2 cm lateral to the intersection of the midline of the femur and the perpendicular drawn to it through the apex of the greater trochanter, an anterior port is created, which is used as an instrumental port at the beginning of the operation. The deformation zone is brought to the bone burr, changing the positions of flexion and extension, internal and external rotation of the lower limb, and until the appearance of spring resistance of the fibers of the lateral joint capsule and the ileofemoral ligament, resection of excess bone mass of the anterior surface of the proximal femur within the boundaries of the Cam-deformation is performed. The viewing and instrument ports are changed and the deep fibers of the proximal joint capsule and the ileofemoral ligament are released from the acetabulum. In the presence of Pincer deformity, soft tissues are removed to visualize excess bone mass within the boundaries of the Pincer deformity, and resection of excess bone mass of the anterolateral edge of the acetabulum within the boundaries of the Pincer deformity is performed until radiographic visualization of the absence of intersection of the anterior and posterior edges of the acetabulum. The viewing and instrument ports are replaced. An arthroscope is positioned on the outer edge of the joint capsule fibers, and bone resection of the posterolateral surface of the proximal femur is completed within the boundaries of the Cam deformity by inserting a bone burr from the skin incision of the anterior port into the capsule opening of the proximal anterolateral port, preserving the fibers of the joint capsule and the ileofemoral ligament.EFFECT: method ensures correction of the proximal femur within the boundaries of the Cam-deformation while maintaining the integrity of the structures of the passive capsular-ligamentous stabilizers and eliminates the development of complications in the form of microinstability of the hip joint, anterior dislocation of the femoral head, heterotopic ossification due to maintaining the integrity of the structures of the passive capsular-ligamentous stabilizers and eliminating the development of microinstability of the hip joint, anterior dislocation of the femoral head and heterotopic ossification.1 cl, 1 ex

The utility model discloses a kind of hip joint prostheses for retaining femoral greater trochanter, including femoral proximal end prosthesis, bone healing structure, connecting rod and femoral stem. Femoral proximal end prosthesis includes femoral neck prosthesis and greater trochanter connecting part, preset included angle is formed between the two, greater trochanter connecting part is used for resetting retained femoral greater trochanter;Bone healing structure is arranged at the outside of preset included angle, and is connected with retained femoral greater trochanter by bone growth mechanism;Connecting rod is connected with the bottom end of femoral proximal end prosthesis;Femoral stem is connected with the bottom end of connecting rod, for inserting into femoral medullary cavity.In installation process, perfect femoral greater trochanter does not need to be removed, femoral greater trochanter is successfully retained, so that patient's gluteus medius and vastus lateralis muscle can be retained, the destruction to the stop of gluteus medius and vastus lateralis muscle is avoided, so as to improve the functional recovery effect after operation. The connection of hip joint prosthesis and retained femoral greater trochanter is realized by bone healing structure, and the stability and durability of connection are improved.

Periprosthetic bone fixation plates are disclosed including, for example, periprosthetic proximal femur plate, periprosthetic distal femur plate, periprosthetic humerus plate, periprosthetic ring plate, and periprosthetic troch plate. In use, the periprosthetic bone fixation plates are arranged and configured for use in periprosthetic fractures. That is, the periprosthetic plates include one or more features to facilitate positioning and securement of the bone fixation plate to a patient's bone that previously received a surgically implanted orthopedic device or implant such as, for example, an intramedullary nail, a hip prosthesis, a knee prosthesis, etc. In use, the one or more features are designed and configured to facilitate avoidance of the previous surgically implanted orthopedic device or implant. In addition, the periprosthetic bone fixation plates are arranged and configured to facilitate plating of a longer working length as compared to existing bone fixation plates (e.g., plating from, for example, femoral condyle to greater trochanter).

Provided is a wearable protection device that efficiently protects the human body. According to the present invention, a protection device that is to be worn at the waist of a person to be protected comprises a cushioning part that surrounds at least a portion of the protruding portion of the greater trochanter of the femur of the person to be protected at a gap from the protruding portion.

The present invention provides rotational movement tights that can assist the rotational movement of the wearer's lower body. [Solution] The rotational movement tights 1 comprises a main body 10 configured to be attached to the lower body 110 of the wearer 100, and a tightening part 20 attached to the main body 10 and having greater elasticity than the main body 10. The tightening part 20 is positioned on at least one of the wearer 100's right lower body 111 and left lower body 112 when the main body 10 is attached to the wearer 100's lower body 110. The tightening part 20 is spirally configured to sequentially cover the wearer 100's gluteus maximus, posterior greater trochanter, biceps femoris, posterior joint space, and tibial tuberosity in at least one of the right lower body 111 and left lower body 112. The tightening part 20 includes an anchor part 21. The anchor part 21 diagonally covers the tibial tuberosity from the outside to the inside.
