Protocol - Bone Age
Description
The latest Tanner and Whitehouse Method, sometimes referred to as TW2, involves the interpretation of a radiograph of the left hand and wrist by a trained radiologist. The procedure includes the assessment of regions of interest (ROI) on 20 bones. The ROI include the epiphysis, metaphysis and diaphysis of each bone. The radiologist gives each ROI a numerical score and records the result. The numerical score of each ROI is summed to produce a total score.
Specific Instructions
This protocol must be administered by a radiologist professionally trained to evaluate bone age via the Tanner and Whitehouse Method. Since the online tool collects personal identifying information (PII), the researcher should use the individual’s initials and not include other identifiable information such as the person’s address.
Availability
This protocol is freely available; permission not required for use.
Protocol
The Tanner-Whitehouse Test is an online tool which was developed by Lorentz Jantschi and Sorana Bolboaca and is available at:
vl.academicdirect.org/medical_informatics/bone_age/v1.0/
The tool describes various findings associated with each of the following 20 regions of interest (ROI) of the left hand as seen on x-ray. The ROIs are the:
- Radius
- Ulna
- First, third, and fifth metacarpal
- Proximal phalanx of the thumb, third finger, and fifth finger
- Middle phalanx of the third and fifth finger
- Distal phalanx of the thumb, third finger, and fifth finger
- Capitate
- Hamate
- Triquetral
- Lunate
- Scaphoid
- Trapezium
- Trapezoid
Users select a finding that matches what they see on the x-ray. Each finding has two x-ray images, a drawing and a written description. Once a selection is made for each ROI, the users enters the patient’s name*, address, x-ray date, diagnostic, gender, weight, height and age (in years and months, for example 11 years and 3 months). Then the program calculates the individual’s bone age based upon the standard atlas associated with the Tanner and Whitehouse method. *See Specific Instructions for suggestions regarding personal identifying information.
