Disability Table For Common Fractures

As an aid in estimating probable periods of disability from various skeletal fractures, the table shown below has been prepared. However, since the effect of injuries on individuals varies from person to person it must be recognized that the disability periods shown are not exact and should be used only as a general guide.

Fracture	Disability (Weeks)
Astragulus (Ankle)	16-34
Clavicle	4-6
Colles	4-10
Femur	26-52
Fingers	3-6
Hand	3-6
Humerus	8-16
Knee Joint	12-24
Metatarsals	5-8
Patella	12-18
Pelvis	6-12
Ribs	2-4
Scapula	5-8
Sternum	2-4
Tarsals	6-12
Tibia	16-34
Toes	2-4
