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 chondrodysplasia.
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.

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.
