BBH, cranial height


The maximum length between bregma (at the confluence of the coronal and sagittal sutures) and basion (at the anteroinferior margin of the foramen magnum, between the occipital condyles). This measure can be taken with the calipers placed either laterally or posteriorly, relative to the cranium.

(Spreading caliper)


C2, 2nd cervical vertebra height


The most superior point of the odontoid process (dens) to the most inferior point of the anterioinferior rim of the vertebral body.

(Spreading caliper)


C3 - C7, 3rd-7th cervical vertebra height


The maximum height of the vertebral body, measured in its anterior third, medial to the superiorly curving edges of the centrum.

(Spreading caliper)


T1 - T12, thoracic vertebrae height


The maximum height of the vertebral body, anterior to the rib articular facets and pedicles.

(Spreading caliper)


L1 - L5, lumbar vertebrae height


The maximum height of the vertebral body, anterior to the pedicles, not including any swelling of the centrum due to the pedicles.

(Spreading caliper)

S1, 1st sacral vertebra height


The maximum height between the anterior-superior rim of the body (i.e., the sacral promontory) and its point of fusion/articulation with the second sacral vertebra. This most commonly occurs in the midline. Measure with the calipers paral- lel to the anterior surface of S1.

FBL, femoral physiological length


Place the condyles on the stationary end of the osteometric board, flat against the horizontal plane. Set the mobile end against the most superior aspect of the femoral head, parallel to the stationary end. Measure at maximum length.

(Osteometric board)


TFL, tibial length


Place the medial malleolus on the stationary end of the osteometric board, with the shaft of the tibia parallel to the long axis of the board. Set the mobile end against the most superior aspect of the lateral condyle of the tibia, parallel to the stationary end.

TCH, talus - calcaneus height


Articulate the talus and the calcaneus, using the right hand for the left tarsals and vice versa. Use one hand to stabilize the articulation, point the distal articulations away from your palm, with a thumb holding the bones together superior to the peroneal tubercle (where the talus and calcaneus meet), an index finger on the opposite side lateral to the trochlea of the talus, and a middle finger in the sustentacular sulcus. Place the trochlea against the stable end of the osteometric board, with both lateral and medial edges of the trochlea contacting the board. Position the trochlea of the talus so that the stable end of the board forms a tangent to the midpoint of the trochlear surface. Place the mobile end of the osteometric board against the most inferior point of the calcaneal tuber, parallel to the stable end.
