Description
Technical Field
The utility model belongs to medical equipment, concretely relates to shin bone tuberosity fracture coaptation board.
Background
The tibial tubercle is a bony prominence 3cm distal to the tibial plateau, is the most anterior part of the proximal epiphyseal part of the tibia, and participates in the growth of the proximal tibia. The epiphyses of the tibial tubercles after 18 years of age fuse with the tibial stem. Tibial tuberosity epiphyseal avulsion fracture occurs when the knee joint is strongly flexed and the quadriceps femoris muscle is severely contracted. Juvenile tibial tubercle avulsion fractures occur at a higher rate than adults.
For adult tibial tubercle avulsion fracture, the fracture is mostly caused by high-energy injury, the fracture pieces are often obviously displaced, the conservative treatment is not good, and the surgical treatment is frequently needed.
At present, for patients with tibial tubercle avulsion fracture, screws are mostly used for fixing and displacing fracture. As the tibial tubercle is used as the insertion point of the patellar ligament and is an important component of the knee extension device, the part can be under strong traction force when the knee joint extends and bends, a patient after internal fixation urgently needs early functional exercise, simple screw fixation is difficult to maintain stability, and particularly, the comminuted tibial tubercle avulsion fracture is difficult to maintain stability and is easy to have the risk of fracture re-displacement.
