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.

Comorbid Conditions

Factors Influencing Duration

Factors that might influence the length of disability include the joint involved, the underlying disease process, the individual's tolerance of the resulting stiffness, and the individual's ability to modify work requirements after disability. The time to complete healing or fusion varies from 3 months to 9 months, and at least some degree of modified activities will be present until the bone fusion is solidly healed.

Medical Codes

ICD-9-CM:
81.11 - Ankle Arthrodesis; Tibiotalar Fusion
81.12 - Triple Arthrodesis; Talus to Calcaneus and Calcaneus to Cuboid and Navicular
81.13 - Subtalar Fusion
81.14 - Midtarsal Fusion
81.15 - Tarsometatarsal Fusion
81.16 - Metatarsophalangeal Fusion
81.17 - Fusion of Foot, Other
81.18 - Subtalar joint arthroereisis
81.20 - Arthrodesis of Unspecified Joint
81.21 - Hip Arthrodesis
81.22 - Knee Arthrodesis
81.23 - Shoulder Arthrodesis
81.24 - Arthrodesis of Elbow
81.25 - Carporadial Fusion
81.26 - Metacarpocarpal Fusion
81.27 - Metacarpophalangeal Fusion
81.28 - Interphalangeal Fusion
81.29 - Arthrodesis of Other Specified Joints

Rehabilitation

The hand (thumb and finger joints), wrist, and ankle are commonly seen for rehabilitation following an arthrodesis. It is important, however, to initially control postoperative pain and swelling for any joint fusion. This initial stage is followed by rehabilitating the individual to regain as much as possible the function of the body part involved. The physical therapist will use various methods to address postoperative symptoms.

Strengthening the muscles that move adjacent joints is important. For example, an individual who has undergone an arthrodesis of the hip would benefit from strengthening exercises for the muscles that move the back of the knee because these muscles must compensate for the loss of joint movement. This strengthening is important to improve an individual's gait. Instruction in the use of an assistive device such as crutches and afterwards a cane may be required shortly after surgery, while the individual progresses to independent walking. Strengthening exercises are equally important for any arthrodesis performed on the upper extremities.

Modifications may need to be made by the physical therapist for those who have arthritis or other conditions near the joint that underwent arthrodesis. Rehabilitation will also vary depending upon the body part and joint(s) involved.
