What is a Knee-Height Caliper?

A knee height caliper is used to measure the height of bedridden patients, elderly persons, and persons in wheelchairs, by means of measuring the height of the leg.  A knee height caliper is usually rigid metal and about 80cm long (just under 2.5 ft).  It may sometimes be referred to as a rigid segmometer.

What is a Segmometer?

A segmometer is another measurement tool that can be used for knee height measurement as well as demi-span (armspan to mid-chest) and bone lengths.  There are two styles: flexible and rigid. 

Rigid segmometer

A rigid segmometer is very similar to a knee height caliper.  It consistes of a long steel or metal rod with a sliding arms.

Flexible segmometer

A flexible segmometer is a modified tape measure with tips.  The advantage of a flexible segmometer is that is very compact and thus easier to transport.  Its compact size also makes it ideal for shorter bone length measuremenths.

How Much Does a Knee Height Caliper Cost?

The Shorr knee height caliper price is around $300-350.  A flexible segmometer costs around $65-140, and a rigid segmometer costs around $180+.

How do you use a knee-height caliper?

The right leg of the patient should form a 90 degree angle, place the fixed blade of the caliper on the distal end of the calcaneus and the sliding blade on the anterior side to the external condyle of the femur so that the axis of the caliper aligns with the tibia.
