Apophyseal avulsion fractures are usually the result of a sudden forceful concentric or eccentric contraction of the muscle attached to the apophysis. Like other pediatric fractures, apophyseal avulsion fractures fail through the physis. 2 The primary age for these injuries to occur is between 14 and 25 years. 1,3,4
What is an apophyseal injury?
Answer: Apophyseal injuries are stresses to the growth plate in adolescent athletes. They can range from just a stress reaction with inflammation in the area and soreness to a complete fracture. Fractures can occur during explosive movements where the muscle is contracted forcibly causing it to pull the bone away from its origin.
What is a posterior ring apophyseal fracture?
Posterior ring apophyseal fracture or separation, also called limbus fracture, occur in the immature skeleton, most commonly in the lumbar spine. They represent bony fractures of the vertebral body rim at the site of attachment of the Sharpey fib... Articles Log In Cases Sign Up Courses Quiz Donate About Menu Search
What is apophyseal joint in the spine?
Apophyseal Joint Definition. An apophyseal joint is a point where two or more bones join in the spine. The spinal joint is encapsulated by connective tissues, coated with cartilage and lubricated with synovial fluid to enable smooth joint articulation. Each vertebra has a pair of apophyseal joints- one on the left and one on the right.
How long does it take for an apophyseal fracture to heal?
But an apophyseal fracture can take 6-8 weeks to heal properly and it is important to monitor the progression of the healing so the athlete can return at an appropriate time without reaggravating the injury.
What is a common Apophyseal injury?
Common apophyseal injuries, and their sites, include Sever's disease (posterior calcaneus), Osgood-Schlatter disease (tibial tuberosity), Sindig-Larsen-Johansson syndrome (inferior patella), medial epicondylitis (humeral medial epicondyle) and apophysitis of the hip (iliac crest, ischial tuberosity).
What is Apophyseal?
An apophyseal joint is a point where two or more bones join in the spine. The spinal joint is encapsulated by connective tissues, coated with cartilage and lubricated with synovial fluid to enable smooth joint articulation. Each vertebra has a pair of apophyseal joints- one on the left and one on the right.
Where do Apophyseal injuries occur?
The apophysis is the location of a growth plate with a muscle attachment - there are several in the pelvis where the various thigh muscles attach. Apophysitis involves inflammation of one of these with associated dull pain, and is typically associated with muscle overuse.
What is an Apophyseal avulsion fracture?
Apophyseal avulsion fractures of the pelvis are injuries that typically occur in adolescent athletes [1]. At this age the secondary ossification at the apophyses coincides with the hormonally induced strengthening of the muscles [2].
What is pedicle in anatomy?
A pedicle is a stem or stalk of tissue that connects parts of the body to each other. The brain has many pedicles (such as the cerebral pedicle) that connect areas of the brain to each other. Skin tags are small pieces of skin tissue that connect to the body with a pedicle.

How long does it take to heal apophysitis?
Treatment. Apophysitis is a self-limiting process. Most patients will return to full activity following 4-6 weeks of rest or reduced activity.
How long does apophysitis take to heal?
How is apophysitis treated? Rest and physical therapy are required to completely heal an inflamed apophysis and return back to sport successfully. Usually this process takes anywhere from 4-8 weeks depending on the stage of injury, but every athlete is different.
How do you recover from apophysitis?
Ice should be applied to the painful area for 15-20 minutes as often as every 2-3 hours until the pain goes away. Once you can tolerate daily activities without pain, you can start gently stretching and strengthening the muscles that attach to the affected apophysis (the hip flexors and abdominal muscles).
What is the difference between epiphysis and apophysis?
An apophysis is a growing center which, as its name indicates, grows (physis) upon (apo) the mother bone. It differs from the epiphysis in that with the development of the ossification center all growth is completed.
How long does it take for a pelvic avulsion fracture to heal?
Pelvic avulsion fractures require a long period of rest and changes in activity in order to heal. Typically, these injuries will get better with four to six weeks of rest.
What is the most common avulsion fracture in the pelvic area?
The most frequently affected sites are the Anterior Superior Iliac Spine, Anterior Inferior Iliac Spine, and Ischial Tuberosity.
What is the difference between epiphysis and apophysis?
An apophysis is a growing center which, as its name indicates, grows (physis) upon (apo) the mother bone. It differs from the epiphysis in that with the development of the ossification center all growth is completed.
What does complete avulsion mean?
An avulsion fracture occurs when a small chunk of bone attached to a tendon or ligament gets pulled away from the main part of the bone. The hip, elbow and ankle are the most common locations for avulsion fractures in the young athlete.
Where is Pars Interarticularis?
The pars interarticularis (pars) lies between the superior and inferior articular process bilaterally at each vertebral level. Anatomically, one can describe the pars as the region between two, one superior and one inferior, zygapophyseal joints.
Clinical Presentation
Pathology
- The ring apophysis is a secondary ossification center of the vertebral endplate connected to the intervertebral disc. It is firmly attached to disc fibrous annulus through Sharpey fibers and its ossification occurs at 4-6 years old. In the first years of life, the junction between ring apophysis and the rest of vertebral body is made through a cart...
