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.

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.

Factors Influencing Duration

The severity of the fracture (i.e., open or closed, simple or comminuted, stable or displaced) and the treatment required (i.e., closed reduction and a cast versus surgery and internal/external fixation) will affect disability. The age of the individual and any comorbid conditions and / or complications may also affect disability. Individuals with uncomplicated fractures who are employed in sedentary jobs may return to work after about a week, but individuals with complicated fractures employed in jobs requiring physical labor or mobility may need 3 to 6 months for complete healing.

Medical Codes

ICD-9-CM:
823.00 - Closed Fracture of Upper End of Tibia Alone
823.01 - Closed Fracture of Upper End of Fibula Alone
823.02 - Closed Fracture of Upper End of Fibula with Tibia
823.10 - Open Fracture of Upper End of Tibia Alone
823.11 - Open Fracture of Upper End of Fibula Alone
823.12 - Open Fracture of Upper End of Fibula with Tibia
823.20 - Closed Fracture of Shaft of Tibia Alone
823.21 - Closed Fracture of Shaft of Fibula Alone
823.22 - Closed Fracture of Shaft of Fibula with Tibia
823.30 - Open Fracture of Shaft of Tibia Alone
823.31 - Open Fracture of Shaft of Fibula Alone
823.32 - Open Fracture of Shaft of Fibula with Tibia
823.80 - Closed Fracture of Tibia Alone, Unspecified Part
823.81 - Closed Fracture of Fibula Alone, Unspecified Part
823.82 - Closed Fracture of Fibula with Tibia, Unspecified Part
823.90 - Open Fracture of Tibia Alone, Unspecified Part
823.91 - Open Fracture of Fibula Alone, Unspecified Part
823.92 - Open Fracture of Fibula with Tibia, Unspecified Part

Complications

Possible complications include delayed union or nonunion, misalignment of the bone fragments (malunion), and leg shortening in the case of a seriously comminuted fracture. Skin loss due to the thinness of the skin over the tibia, infection in the bone (osteomyelitis), joint stiffness, or loss of knee motion are other complications. If the fracture involves the knee or ankle joint, traumatic arthritis may occur. Other complications include compartment syndrome; injury to the common or deep peroneal nerves, which may cause foot drop (typically with fibular fractures); and injury to the popliteal artery (especially with upper tibial fractures). Complex regional pain syndrome and fat embolism may also occur. Amputation may be necessary if there is massive damage to or infection of soft tissues in the leg.
