The incidence of metaphyseal
distal ulna fracture in association with distal radius fractures was 15 of 512 or 2.
Because, good metaphysical stem fit is considered to be one of the major goals to optimize metaphyseal
load transfer in cemented or cementless femoral stem, and each also may be selected according to the metaphyseal
shape (Noble et al.
To prove the hypothesis, the following tests should be performed: biomechanical studies at the supracondylar metaphyseal
level on the border of the distal humerus diaphysis using the finite element method, where the gap would be done at the level of distal humerus 25 mm above the fossa olecrani (Fig.
Finally, the patient was treated for precocious puberty due to 11-[beta]-hydroxilase deficiency and Schmid metaphyseal
The absence of formation of normal primary spongiosa in the metaphysis, the presence of a thin seal of bone at the chondro-osseous junction, with abnormal metaphyseal
vascular invasion and arrest of endochondral growth, these findings suggest an uncoupling of endochondral and perichondral growth, and thus, dumbbell-shaped morphological structure of the osseous metaphysis seen in these patients.
The characteristic radiographic features include: (i) delayed epiphyseal ossification and irregular metaphyses of the long bones with small capital femoral epiphyses, short femoral necks and irregular, flared metaphyseal
borders, and small pelvis and poorly modelled acetabulae with irregular margins that may be sclerotic, especially in older individuals; (ii) significant brachydactyly, particularly short metacarpals and phalanges with irregular metaphyses and small, irregular carpal bones; and (iii) anterior beaking or tonguing of the vertebral bodies, biconvex vertebral endplates, and platyspondyly in childhood.
This lesion arises from the metaphyseal
region of the long bones as a bony excrescence contiguous with the medullary compartment that characteristically points away from the adjacent joint.
Lesions are typically located in the metaphyseal
region of long bones, with the distal femur and proximal tibia making up approximately 50% of all cases.
Clinical and radiographic features of achondroplasia Clinical features Radiographic features Disproportionate short stature Long bones: Short, robust tubular bones; generalised metaphyseal
Large head with frontal bossing changes (may be mild) Mid-face hypoplasia with depressed Spine: narrowing of the nasal bridge interpedicular distance in lumbar spine Rhizomelic shortening of the arms and legs Pelvis: rounded ilia and horizontal acetabulae; narrow Brachydactyly, often with trident sacrosciatic notches configuration of the hands Femurs: proximal radiolucency of Bowed legs femoral heads Thoraco-lumbar kyphosis in infancy Exaggerated lumbar lordosis when ambulatory Normal/average intelligence
A diaphyseal (midshaft) fracture in a child less than 3 years old is suspect, and metaphyseal
or epiphyseal fractures beyond the newborn period (also called corner fractures or bucket handle fractures) are virtually diagnostic of abuse.
I was impressed with the straightforward nature of the Simpliciti operation, the instrumentation, and the humeral metaphyseal
Those with inflicted injury were more likely to present with no external signs of trauma, subdural hematoma, cerebral edema, seizures, and rib, long bone, or metaphyseal
fractures compared with those with accidental injuries.
