Weight Bearing Restriction

Weight Bearing Restriction

Due to the age at onset of Perthes disease, it can be a challenge to get an active child to understand he or she must “take it easy” especially during periods without pain. Furthermore, being told to give up a favorite hobby or sport can impact your child’s mood in a big way. Still, weight bearing restriction remains a cornerstone of conservative treatment, and it’s not as simple as your might think. Here’s the scoop on the many levels of weight bearing.

NWB – no weight on the leg which has the Perthes
PWB – partial weight bearing
TTWB – toe touch weight on side with Perthes – toes only on ground, uses assistive device to “unload” weight
FFWB – foot flat weight on side with Perthes – places entire foot on ground, but uses assistive device to “unload” weight
% of body weight (ie. 20% of 50# = 10# – practice on bathroom scales)
WBAT – weight bearing as tolerated – weight on the leg which has the Perthes – with or without devices
