Systems, devices, and methods for measuring an under foot load profile of a tibial fracture patient during a period of partial weight bearing are described. The system may include a walking boot cast. A housing, including an inner surface and an upper surface that cooperate to define an inner cavity, may be oriented with respect to a patient's tibia. The upper surface is slidably received within the inner cavity in a piston and cylinder configuration. The system may include a pressure sensor configured to monitor the load profile of a patient during the desired period of partial weight bearing. The pressure sensor may be located below the upper surface. The system may include a noncompressible force transmitter positioned within the inner cavity and at least partially encapsulating an upper portion of the pressure sensor to transmit pressure within the housing to the pressure sensor.

The invention discloses a pedestrian leg protection device of an automobile. The pedestrian leg protection device is arranged at the front end of the automobile and comprises a support beam and two or more buffer fixing assemblies, wherein each buffer fixing assembly comprises a support fixing part, a connecting part and a buffer part; the connecting part comprises a first connecting section, a second connecting section opposite to the first connecting section, and a third connecting section connected between the first connecting section and the second connecting section; the first connecting section is connected to the support beam; the second connecting section is connected to the buffer part; one end, far away from the second connecting section, of the buffer part is fixedly connected to the front end of the automobile; the third connecting section is provided with a rotary shaft; the connecting part is rotatably connected to the support fixing part by taking the rotary shaft as a rotary center; one end, far away from the third connecting section, of the support fixing part is fixedly connected to the front end of the automobile. According to the pedestrian leg protection device, a pedestrian can be prevented from being involved in the bottom of the automobile and the risk of lower limb tibial fracture of the pedestrian can be effectively lowered.

A novel interlocking intramedullary rod assembly which allows the surgeon to (i) secure a first bone fragment of a fractured bone (e.g., a distal bone fragment) to the interlocking intramedullary rod assembly in a fixed position, (ii) secure a second bone fragment of the fractured bone (e.g., a proximal bone fragment) to the interlocking intramedullary rod assembly in an adjustable manner, and (iii) thereafter selectively pivot the second bone fragment (e.g., the proximal bone fragment) relative to the first bone fragment (e.g., the distal bone fragment) so as to secure the two bone fragments in position relative to one another with the desired orientation.

The invention relates to a postoperative fixation device used for tibial fracture. The postoperative fixation device comprises a fixation board. Multiple toothed wheels are distributed along the length direction of the fixation board and provided with threaded rods which coaxially slide with the toothed wheels. The threaded rods are in threaded connection with the fixation board. Multiple vertical sliding grooves, corresponding to the toothed wheels one by one, are arranged in the fixation board. The vertical sliding grooves are internally provided with sliding blocks and springs disposed above the sliding blocks. The lower ends of the sliding blocks are hinged onto pressing semi-rings through ball bodies. The sliding blocks are equipped with press rods. The lower parts of the press rods are in threaded connection with the sliding blocks. The sliding blocks are provided with rotating disks capable of horizontally rotating. The rotating disks and the press rods are coaxially arranged. The rotating disks are vertically and slidably connected to upper parts of the press rods. The sliding blocks are equipped with torsion springs disposed above the rotating disks. Two ends of each torsion spring are connected to a sliding block and a rotating disk. Push rods, disposed above the rotating disks and capable of sliding, are arranged on the sliding blocks. The front ends of the push rods contact the threaded rods. The push rods are provided with guide rods. The rotating disks are equipped with spiral through grooves, in which guide rods are arranged. A toothed rack capable of sliding is arranged on the fixation board and can be meshed with the toothed wheels.
