What is a classic metaphyseal lesion?
What is a classic metaphyseal lesion?
Abstract. Background: It is widely accepted that the classic metaphyseal lesion (CML) is a traumatic lesion, strongly associated with abuse in infants. Nevertheless, various non-traumatic origins for CMLs continue to be suggested in medical and legal settings.
What is the most common orthopedic injury in Nonaccidental trauma?
The most common orthopaedic injuries were fractures of the femur or humerus, and most of those fractures occurred in children younger than 2 years.
How do corner fractures occur?
Corner Fractures and Child Abuse In a circumstance of abuse, an adult may grab, twist, or shake a child’s limb in frustration, causing this type of injury. Shaking the child, causing the limbs to move back and forth, can also cause a bucket-handle fracture.
What is Nonaccidental injury?
Non-accidental trauma (NAT) is an injury that is purposefully inflicted upon a child—in other words, child abuse. Often the injury is to the skin and soft tissue, but approximately a third of NATs are fractures.
What is a metaphyseal corner fracture?
Metaphyseal fractures are also known as corner fractures, bucket handle fractures or metaphyseal lesions. It refers to an injury to the metaphysis which is the growing plate at each end of a long bone (such as tibia, femur, etc).
What is a metaphyseal fracture definition?
What is metaphyseal bone?
The metaphysis is the trumpet-shaped end of long bones. It has a thinner cortical area and increased trabecular bone and is wider than the corresponding diaphyseal part of the bone. Periosteal bone forms in the area joining the diaphysis to the epiphysis.
Is the classic metaphyseal lesion associated with other traumatic injuries?
Background: It is widely accepted that the classic metaphyseal lesion (CML) is a traumatic lesion, strongly associated with abuse in infants. Nevertheless, various non-traumatic origins for CMLs continue to be suggested in medical and legal settings. No studies to date systematically describe the association of CMLs with other traumatic injuries.
How are classic metaphyseal lesions differentiated from tissue processing artifacts?
Classic metaphyseal lesions were not differentiated from tissue processing artifacts. Bleeding and callus were uncommon in spite of the vascular nature of the metaphysis.
What are the similarities between classic metaphyseal lesions and healing rickets?
Several similarities exist between classic metaphyseal lesions and healing rickets, including excessive hypertrophic chondrocytes. “Bucket-handle” and “corner fracture” classic metaphyseal lesions resemble healing rickets within the growth plate and the perichondrial ring, respectively.
How are metaphyseal abnormalities identified in the pathophysiology of endometriosis?
These metaphyseal abnormalities were identified from postmortem radiography and correlated with microscopy. The authors concluded the metaphyseal alterations represented partial or complete planar microfractures that transected the primary spongiosa adjacent to the growth plate.
