Is the tibial tuberosity an Apophysis?
Is the tibial tuberosity an Apophysis?
Tibial tubercle is entirely cartilagenous (age < 11 years) Apophysis forms (age 11 to 14 years) Apophysis fuses with the proximal tibial epiphysis (age 14 to 18 years)
What is tibial tubercle apophysis?
The tibial tubercle develops at the anterior part of the proximal tibia as a secondary ossification centre which fuses with the tibia. This ossification centre is separated from the main tibia by a physis (apophysis) which is less resistant to tensile stresses than bone.
When does the tibial tuberosity ossify?
Results: At 10 years of age, the anterior tibial tuberosity was ossified in 50% of the girls but in only 25% of the boys. In all the girls, the anterior tibial tuberosity was ossified at 11 years, fusion of the anterior tibial tuberosity with the epiphysis had started at 12 years, and fusion was complete by 17 years.
What condition is it when there is an Apophysitis at the insertion of the patellar tendon on the tibial tubercle?
Osgood-Schlatter disease (OSD, also called Lannelongue’s disease) is a condition in which the patellar tendon insertion on the tibial tuberosity becomes inflamed [1-2]. It is a well-known condition in late childhood characterized by pain over the tibial tuberosity along with a bony prominence.
What is a Apophysis?
The apophysis is a site of tendon or ligament attachment, as compared to the epiphysis which contributes to a joint, and for that reason, it is also called ‘traction epiphysis’. When unfused, apophyses can easily be mistaken for fractures.
What is Sinding Larsen Johansson syndrome?
Sinding-Larsen-Johansson (SLJ) syndrome is pain at the bottom of the kneecap (patella). It is caused by swelling and irritation of the growth plate there. A growth plate is a layer of cartilage near the end of a bone where most of the bone’s growth happens.
What causes tibial tubercle pain?
A bump can form at the tibial tuberosity because the separated growth plates keep growing and expanding. The area between the bone fragments fills in with new tissue, either cartilage or bone. The new tissue causes the tibial tuberosity to become enlarged and painful.
What is Larsen Johansson disease?
What causes Osgood Schlatter disease?
What causes Osgood-Schlatter disease? Osgood-Schlatter disease is caused by irritation of the bone growth plate. Bones do not grow in the middle, but at the ends near the joint, in an area called the growth plate. While a child is still growing, these areas of growth are made of cartilage instead of bone.
Is Sinding-Larsen-Johansson syndrome the same as Osgood-Schlatter?
The Sinding-Larsen-Johansson syndrome has a pathogenesis similar to that of the Osgood-Schlatter disorder and is the result of excessive force exerted by the patellar tendon on the lower pole of the patella.
What is an unfused apophysis?
What is the function of the apophysis?
Apophysis of the greater trochanter: The apophysis of the greater trochanter significantly contributes to the lever arm length of the hip joint. Its growth activity triggers the neck-shaft angle and finally the centration of the hip joint.
When does the tibial tubercle fuse with apophysis?
Tibial tubercle is a secondary ossification center age <11y, tubercle is cartilaginous. age 11-14y, apophysis forms. age 14-18y, apophysis fuses with tibial epiphysis.
What is the radiological appearance of an unfused tibial tubercle?
The radiological appearance in addition to the absence of pain or swelling at the same level is suggestive of an unfused ossification center of the tibial tubercle (incidental finding), and should not be mistaken for an avulsion fracture of the tibial tuberosity or Osgood-Schlatter disease.
Can a unfused tibial tubercle be an avulsion fracture?
The radiological appearance in addition to the absence of pain or swelling at the same level is suggestive of an unfused ossification center of the tibial tubercle (incidental finding), and should not be mistaken for an avulsion fracture of the tibial tuberosity or Osgood-Schlatter disease. 1.
How to treat ossification of the tibial tuberosity?
In x-rays, a regular ossification (ossicle) is demonstrated over the tibial tuberosity. Treatment includes conservative and surgical options. Conservative treatment includes modifying physical activities, using ice packs, nonsteroidal anti-inflammatory drugs (NSAIDs), braces, and pads.
