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. 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.

Comorbid Conditions

Factors Influencing Duration

Factors that may influence length of disability include the extent of the laminectomy or laminotomy procedure; surgical site within the spinal column; underlying cause of the disorder and its severity; procedures performed concurrently with laminectomy, such as discectomy or fusion; occurrence of complications; individual's job requirements; individual's ability to modify work activities; and individual's compliance with treatment and rehabilitation.

The duration of disability is highly variable, depending on whether the root compression is cervical, thoracic, lumbar, or sacral; whether the disorder involves the spinal cord; and whether the individual's job classification is sedentary, light, medium, heavy, or very heavy work. Duration assumes no persisting spinal cord or cauda equina deficit.

Medical Codes

ICD-9-CM:
03.0 - Exploration and Decompression of Spinal Canal Structures
03.02 - Reopening of Laminectomy Site
03.09 - Exploration and Decompression of Spinal Canal, Other: Decompression: Laminectomy or Laminotomy; Expansile Laminoplasty; Exploration of Spinal Nerve Root; Foraminotomy

Prognosis

The predicted outcome of laminectomies and laminotomies is contingent on the history of the disorder, extent of damage, number of vertebrae involved, and location within the spinal column. The success of discectomy in relieving back pain and symptoms involving the limbs depends heavily on patient selection. Improvement after laminectomy and laminotomy includes decreased pain, often with decreased pins-and-needles sensation (tingling or numbness) and decreased weakness, and improved function.

Review of the literature suggests that up to 85% of individuals have good to excellent results following lumbar laminectomy for disc excision. Between 25% and 75% of individuals improve following laminectomy, between 15% and 30% are unchanged, and between 5% and 50% worsen, while the incidence of recurring disc herniation following laminectomy with discectomy is 5% to 37% (Choy).
