Sedentary Work Exerting up to 10 pounds (4.5 kg) of force occasionally and/or a negligible amount of force frequently or constantly to lift, carry, push, pull, or otherwise move objects, including the human body. Sedentary work involves sitting most of the time, but may involve walking or standing for brief periods of time. Jobs are sedentary if walking and standing are required only occasionally and other sedentary criteria are met.

Light Work Exerting up to 20 pounds (9.1 kg) of force occasionally and/or up to 10 pounds (4.5 kg) of force frequently, and/or negligible amount of force constantly to move objects. Physical demand requirements are in excess of those for Sedentary Work. Light Work usually requires walking or standing to a significant degree. However, if the use of the arm and/or leg controls requires exertion of forces greater than that for Sedentary Work and the worker sits most the time, the job is rated Light Work.

Medium Work Exerting up to 50 (22.7 kg) pounds of force occasionally, and/or up to 25 pounds (11.3 kg) of force frequently, and/or up to 10 pounds (4.5 kg) of forces constantly to move objects.

Heavy Work Exerting up to 100 pounds (45.4 kg) of force occasionally, and/or up to 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Very Heavy Work Exerting in excess of 100 pounds (45.4 kg) of force occasionally, and/or in excess of 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Job Classification

In most duration tables, five job classifications are displayed. These job classifications are based on the amount of physical effort required to perform the work. The classifications correspond to the Strength Factor classifications described in the United States Department of Labor's Dictionary of Occupational Titles. The following definitions are quoted directly from that publication.

Factors Influencing Duration

Cigarette smoking and poor nutritional status slow wound healing. Because assistive devices may be required for drinking and eating, overall health may be affected if nutritional and caloric intake is inadequate.

Complications

Acute complications result from the trauma itself. Complications can also occur from surgical repair of maxillofacial injuries. These include temporary or permanent loss of sensation in the face, loss of the ability to smell and / or taste, cerebrospinal fluid leak, meningitis, sinus infection, infection in the bones (osteomyelitis), injury to the teeth, malocclusion, scars, and other cosmetic concerns. The overall complication rate is 3 times as high if the fracture is treated more than 10 days after initial injury (Chang).

Infection increases the chance of delayed union, nonunion, osteomyelitis, and loss of teeth and bone structure. Infection prolongs hospitalization and disability and increases the financial burden. With any midface fracture or fractures involving teeth, prophylactic administration of antibiotics is recommended.

Approximately 2.4% of mandible fractures result in nonunion (Chang). Nonunion occurs when no future potential exists for the bones to knit together and ultimately heal. Malunion occurs when the bone heals with improper alignment. A delayed union is a healing period longer than 8 weeks and is usually seen when MMF is released prematurely.
