How do you fix a tibial tuberosity?
The tibial tuberosity is reduced and fixed to the tibia by using one or two screws. In children, unicortical fixation may be as good as bicortical fixation. Arthroscopy or arthrotomy may be required to repair damaged menisci and to refashion a smooth articular surface, particularly in type III injuries.
What is tuberosity avulsion?
Abstract. Intro: Tibial tuberosity avulsion fractures are rare fracture patterns accounting for less than 1% of all pediatric fractures. These fractures occur when there is a sudden unbalancing of forces through the patellar tendon that separates the tibial tubercle from the anterior portion of the proximal tibia.
What causes tibial tuberosity fracture?
Tibial tubercle fracture is caused by injury from violent tensile forces on the tibial tuberosity. The force is delivered through eccentric contraction of the extensor mechanism of the knee from either of the following: Violent contraction of the extensors without shortening (eg, springing off when jumping)
Can you break tibial tuberosity?
Fractures of the tibial tuberosity are rare, taking only 3% of the proximal tibial fractures. This traumatic lesion is typical of the growth age, when muscles, tendons and ligaments are stronger than the growth plate.
What is a tibial tuberosity fracture?
Tibial tuberosity fractures are rare fractures that predominately occur in adolescents with the onset of proximal tibial physeal closure. These apophyseal fractures occur almost exclusively in boys, but there are a few cases reported in girls.
What is the treatment for tibial tuberosity?
The fracture of tibial tuberosity is a rare lesion and still more unusual in adults. We describe a case in an adult who suffered a left knee injury due to a fall from height. No risk factors were identified. The lesion was treated with surgical reduction and internal fixation. The rehabilitation met …
Which radiographs are used to diagnose tibial tuberosity?
Plain radiograph Recommended views include an AP and lateral knee radiograph. Optional views include an internal rotation view bringing the tibial tuberosity into profile or a contralateral knee radiograph for comparison. Plain radiographs may demonstrate: widening of open apophysis typically demonstrating a displacement of proximal apophysis
What causes avulsion fractures of the tibial tuberosity apophysis?
Activities involving powerful contraction of the knee extensors, such as springing and jumping movements, can result in avulsion fractures of the tibial tuberosity apophysis. This condition should be distinguished from Osgood-Schlatter disease, a chronic apophysitis of the tibial tuberosity due to recurrent traction injury.
