What causes trabecular microfracture?
Bone marrow edema (BME), bone marrow hemorrhage (BMH), and trabecular microfractures (TMF) comprise a triad of fundamental pathological bone marrow changes that frequently occur as a result of trauma, sports injuries, osteoporosis, inflammation, infection, neoplasms, and even daily physical activities.
What is trabecular bone fracture?
The trabecular fracture zone was defined as the region presenting brittle fracture or plastic deformation of at least one trabecula.
Where is a trabecular fracture?
Trabecular bone fractures are common in the vertebrae and in the metaphyseal and epiphyseal regions of long bones, such as intra-trochanteric or sub-trochanteric fractures of the proximal femur.
Do micro fractures heal stronger?
Despite one misconception, there is no evidence that a bone that breaks will heal to be stronger than it was before. When a bone fractures, it begins the healing process by forming a callus at the fracture site, where calcium is deposited to aid rebuilding, said Dr.
What does trabecular mean?
1 : a small bar, rod, bundle of fibers, or septal membrane in the framework of a body organ or part. 2 : a fold, ridge, or bar projecting into or extending from a plant part especially : a row of cells bridging an intercellular space.
What is a trabecular microfracture?
Bone bruises (also known as bone contusion, trabecular microfracture) are an osseous injury that results from compression of bone structures.
Is cortical or trabecular bone stronger?
Cortical bone is stiffer than trabecular bone, thus can withstand higher stress (~150 MPa) yet lower strain (~2%) prior to failure; whereas the porous nature of trabecular bone provides greater elasticity than cortical bone, thus withstands lower levels of stress (~50 MPa) yet much higher strain (~50%) prior to failure …
Is trabecular bone the same as spongy bone?
cancellous bone, also called trabecular bone or spongy bone, light, porous bone enclosing numerous large spaces that give a honeycombed or spongy appearance.
What is trabecular pattern?
Trabecula is a supportive and connective tissue element which form in cancellous bone. Trabeculae develop in a normal bone and also in a healing bone. The trabecular pattern of growth follows the course of stress lines along the bone and maximum trabeculae develop along the lines of maximum stress.
How long do micro fractures take to heal?
It takes 9 to 12 months for a full recovery.
What is trabecular microfracture?
Trabecular microfracture Healing trabecular microfractures are a common feature in cancellous bone. These lesions, when observed in macerated cancellous bone slices, measure about 500 microns in diameter and surround fractures in trabeculae with microcallus.
What is a micro-trabecular fracture of the ankle?
Micro-trabecular fractures also tend to occur near the knee and ankle, where ligaments and tendons block the minute fractures from view. An MRI is the most effective method of diagnosing a micro-trabecular fracture.According to The Scott and White Memorial Hospital, bone bruises take weeks to many months to heal fully.
Do micro trabecular fractures show up on Xray?
Since the fractures are so small, X-rays of the affected area appear normal. Micro-trabecular fractures also tend to occur near the knee and ankle, where ligaments and tendons block the minute fractures from view. An MRI is the most effective method of diagnosing a micro-trabecular fracture.
Is trabecular microfracture in cancellous bone normal?
Microfractures are the result of normal physical activity. Hence, the widespread occurrence of trabecular microfracture in cancellous bone implies that a reasonable rate of microfracture is physiologically tolerable. There are three putative effects for trabecular microfracture.
