Bro,

Assessment of skeletal maturation by assessing the ossification and maturation of the epiphysis of the hands and wrists and comparing them with standards. Two main systems are used:

1. The Greulich and Pyle method:
the radiograph of the whole hand and wrist is compared with images in the Atlas.

2. The Tanner Whitehouse system:
known as TW2. This is a method, in which a score is assigned to 20 of the epiphyses in the hand and wrist having compared them with the standards in the Atlas. The scores are summed and compared with standard tables.
Bone age is one parameter used in predicting height. Bone age monitoring is done in children on growth hormone therapy, to identify the optimum time for corrective spinal surgery or leg lengthening. Prior to the ossification of the hand epiphysis the ossifation of the distal femora and upper tibial eiphyses and the calcaneum are used. The calcaneus ossifies at 24 weeks gestation, the distal femur at 36 weeks and the upper tibia at 38 weeks. Iliac crest epiphyses fuse between 16 and 20 years.
