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

The region of the spine involved, the surgical technique used, the underlying disease or condition for which the fusion was performed, the presence of complications, and an individual's job requirements may influence the length of disability. The individual's preoperative level of physical fitness and response to surgical treatment also influences the length of disability.

Cigarette smoking decreases the chances of successful spinal fusion as does the use of nonsteroidal anti-inflammatory drugs (NSAIDs) in the early postoperative period.

Medical Codes

ICD-9-CM:
81.00 - Spinal Fusion, Not Otherwise Specified
81.01 - Atlas-axis Spinal Fusion; Craniocervical Fusion by Anterior, Transoral, or Posterior Technique; C1-C2 Fusion by Anterior, Transoral, or Posterior Technique; Occiput C2 Fusion by Anterior, Transoral, or Posterior Technique
81.02 - Other Cervical Fusion of the Anterior Column, Anterior Technique; Arthrodesis of C2 Level or Below: Anterior Interbody Fusion
81.03 - Other Cervical Fusion of the Posterior Column, Posterior Technique; Arthrodesis of C2 Level or Below, Posterolateral Technique
81.04 - Dorsal and Dorsolumbar Fusion of the Anterior Column, Anterior Technique; Arthrodesis of Thoracic or Thoracolumbar Region: Anterior Interbody Fusion; Extracavitary Technique
81.05 - Dorsal and Dorsolumbar Fusion of the Posterior Column, Posterior Technique; Arthrodesis of Thoracic or Thoracolumbar Region, Posterolateral Technique
81.06 - Lumbar and Lumbosacral Fusion of The Anterior Column, Anterior Technique; Anterior Lumbar Interbody Fusion (ALIF); Arthrodesis of Lumbar or Lumbosacral Region: Anterior Interbody Fusion; Anterolateral Technique; Retroperitoneal; Transperitoneal; Direct Lateral Interbody Fusion [DLIF]; Extreme Lateral Interbody Fusion [XLIF]
81.07 - Lumbar and Lumbosacral Fusion of the Posterior Column, Posterior Technique; Facet Fusion; Posterolateral Technique; Transverse Process Technique; Facet Fusion; Posterolateral Technique; Transverse Process Technique
81.08 - Lumbar and Lumbosacral Fusion of The Anterior Column, Posterior Technique; Arthrodesis of Lumbar or Lumbosacral Region, Posterior Interbody Fusion; Axial Lumbar Interbody Fusion [Axialif] ; Posterior Lumbar Interbody Fusion (PLIF); Transforaminal Lumbar Interbody Fusion (TLIF)

Prognosis

Spinal fusion has variable outcomes, with some individuals experiencing a good to excellent outcome and others experiencing a poor outcome. Cervical spine fusions have a high success rate, both in terms of patient outcome and in terms of radiographic fusion status. Even with successful lumbar fusion, back symptoms are not relieved (clinical failure) in many cases. Nonunion may occur, although new technology has contributed to its decreased frequency. Serious complications can have lifelong, debilitating effects.
