In orthopedics, weight bearing is the amount of weight a patient puts on the leg on which surgery has been performed. It is generally described as a percentage of the body weight, because each leg of a healthy person carries the full body weight when walking, in an alternating fashion.
After surgery of the hip, or of the bones of the leg, ankle or foot, it is of the utmost importance for recovery to get the right amount of weight bearing when moving around with crutches or frames.
The grades of weight bearing for each phase of recovery will be determined by the surgeon.
Grades of weight bearing
- Non weight bearing: The leg must not touch the floor. The patient must hop. This is a 0% of the body weight.
- Touch weight bearing: The weight of the leg on the floor while taking a step should be no more than 20% of the body weight.
- Partial weight bearing: The weight can be gradually increased from 20 to 50% of the body weight.
- Weight bearing as tolerated: Ranks from 50 to 100% of the body weight. The patient may increase the weight as he or she feels capable to do so.
- Full weight bearing: The leg can now carry a 100% of the body weight on a step.
