What is avulsive cortical irregularity?
Abstract. Avulsive cortical irregularity, a benign condition occurring only among children and adolescents, has been known to simulate malignancy not only radiologically but also microscopically.
What does cortical irregularities mean?
An abnormal irregularity of cortical bone. [ from HPO]
Is cortical irregularity serious?
Conclusions: A cortical irregularity in the transition zone of the radial neck and head seems to be a reliable radiographic sign of an underlying radial head fracture. The absence of the cortical irregularity can be used to correctly identify a non-fractured radial head.
What causes cortical desmoid?
Cortical desmoid (also called tug lesion or periosteal desmoid) is an irregularity of the distal femoral cortex caused by repetitive stress at the attachment of the adductor magnus aponeurosis. It is most commonly seen in adolescents and is usually asymptomatic. It is a benign and self-limiting lesion.
What is fibrous cortical defect?
Category: Bone and Joint. To begin with, the fibrous cortical defect is a benign fibrous tumour occurring, in the cortex of the metaphysis, only in the long bones of children and young adolescents. The term “fibrous cortical defects” has been given, as these lesions are composed of fibrous tissue.
What does cortical mean in medical terms?
Medical Definition of cortical 1 : of, relating to, or consisting of cortex cortical tissue. 2 : involving or resulting from the action or condition of the cerebral cortex cortical blindness. Other Words from cortical. cortically \ -k(ə-)lē \ adverb.
What does the cortical bone do?
Cortical bone is the dense outer surface of bone that forms a protective layer around the internal cavity. This type of bone also known as compact bone makes up nearly 80% of skeletal mass and is imperative to body structure and weight bearing because of its high resistance to bending and torsion.
What is a desmoid tumor?
Desmoid tumors are also known as aggressive fibromatosis or desmoid-type fibromatosis. A desmoid tumor can occur anywhere in the body since connective tissue is found everywhere in your body. Desmoid tumors are often found in the abdomen, as well as the shoulders, upper arms, and thighs.
How long does it take for a distal femur to heal?
Depending on health and injury pattern this bone can take 3-4 months to heal without surgery. Physical therapy for knee range of motion is started around 6 weeks once bone has healed enough to prevent displacement with motion.
What is a cortical irregularity in the femur?
On xrays, at the distal posterior medial end of the femur, just above the growth plate, a cortical irregularity is seen, either with lucency, reactive bone formation, sclerosis, or a combination of these.
What are cortical avulsive desmoids?
Cortical desmoids, also known as cortical avulsive injuries, Bufkin lesion or distal femoral cortical defects/irregularities, are a benign self-limiting entity that are common incidental findings. This is a classic ” do not touch ” lesion, and should not be confused with an aggressive cortical/periosteal process (e.g. osteosarcoma).
Which physical findings are characteristic of avulsive cortical irregularity?
The avulsive cortical irregularity is commonly observed in children and adolescents along the posteromedial aspect of the distal femoral metaphysis. The described lesion has a highly characteristic location and roentgenographic appearance with some variation produced by the developmental stage.
What are cortical desmoids in femur?
Cortical desmoids are classically seen at the posteromedial aspect of the distal femur. They can be bilateral in approximately one-third of cases ref. It is related to repetitive stress at the attachment of the medial head of gastrocnemius or less commonly the lateral head of gastrocnemius distal or adductor magnus attachment sites 10.
