The Tanner scale (also known as the Tanner stages or sexual maturity rating (SMR)) is a scale of physical development as pre-pubescent children transition into adolescence, and then adulthood. The scale defines physical measurements of development based on external primary and secondary sex characteristics , such as the size of the breasts ...
The New Ballard Score allows scores of −1 for the criteria, hence making negative scores possible. The possible scores then range from −10 to 50, the gestational range extending up to 20 weeks. (A simple formula to come directly to the age from the Ballard Score is Age=((2*score)+120)) / 5. Maturity Rating:
An alternative approach to the atlas method just described is the so-called "single-bone method" where maturity scales are assigned to individual bones. [ 7 ] [ 8 ] Here, a selection of bones are given a score based on their perceived development, a sum is totaled based on the individual bone scores, and the sum is correlated to a final bone age.
[1] A typical five-point grading scale is as follows: Grade 1 is given when the ilium (bone) is calcified at a level of 25%; it corresponds to prepuberty or early puberty. Grade 2 is given when the ilium (bone) is calcified at a level of 50%; it corresponds to the stage before or during growth spurt.
Thelarche, also known as breast budding, is the onset of secondary breast development, often representing the beginning of pubertal development. [1] It is the stage at which male and female breasts differentiate due to variance in hormone levels; however, some males have a condition in which they develop breasts, termed gynecomastia .
Grade 3 (borderline/moderate need) 3.a Increased overjet >3.5mm but ≤6mm (incompetent lips) 3.b Reverse overjet greater than 1 mm but ≤3.5mm 3.c Anterior or posterior crossbites with >1mm but ≤2mm discrepancy between the retruded contact position and intercuspal position 3.d Displacement of teeth >2mm but ≤4mm
Posterior labial fusion will be present. Stage 3 shows a further enlarged phallus, with a single urogenital sinus [ 4 ] and almost complete fusion of the labia. Stage 4 looks more male than female, with an empty scrotum and a phallus the size of a normal penis, but not quite free enough of the perineum to be pulled onto the abdomen toward the ...
Bishop score, also Bishop's score or cervix score, is a pre-labor scoring system to assist in predicting whether induction of labor will be required. [1] It has also been used to assess the likelihood of spontaneous preterm delivery. [ 2 ]
