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.

Comorbid Conditions

Factors Influencing Duration

Length of disability depends on the extent of damage at the femoroacetabular joint, the presence of comorbid osteoarthritis, the surgical approach, and the individual’s job requirements.

Medical Codes

ICD-9-CM:
719.45 - Joint Pain; Arthralgia, Pelvic Region and Thigh; Buttock, Femur, Hip (Joint)
719.85 - Other Specified Disorders of Joint; Calcification of Joint; Fistula of Joint, Pelvic Region and Thigh; Buttock, Femur, Hip (Joint)
719.95 - Unspecified Joint Disorder, Pelvic Region and Thigh; Buttock, Femur, Hip (Joint)

Overview

The hip joint is a synovial, ball (femoral head) and socket (pelvic acetabulum) joint (an enarthrosis). When abnormal contact occurs, the femoral head causes painful pinching (impingement) as it meets the acetabulum, compressing and sometimes tearing the cartilaginous ring that surrounds the acetabulum (acetabular labrum). Femoral acetabular impingement (FAI) is most likely to occur during twisting or pivoting activities or at the extreme range of motion when hip joint has become stiff from underlying osteoarthritis.

There are 2 main types of FAI: cam and pincer. With cam (from the Dutch word for "cog") FAI, the ball of the femoral head is not completely rounded at the femoral head-neck junction, which causes an abnormal bulging of the femoral head within the acetabulum (Manaster). This can cause mechanical impingement and damage to the cartilage lining the acetabulum during hip movement. Cam FAI is most common in young, active male patients. With pincer FAI, impingement occurs from abnormal compression of the acetabular cartilage by the femoral head. This may result from an excessively deep socket that limits normal range of motion, an awkwardly oriented socket, or a bone spur (osteophyte) that catches during movement. Pincer FAI is most common in middle-aged women. However, the majority of individuals with FAI exhibit a mixed pattern of cam and pincer types (Ganz, "Etiology"; Shah).

Chronic FAI can result in tears of the cartilage lining the acetabulum (labral tears), complete detachment of the labrum from the acetabulum, cyst formation in the bone of the acetabulum, and early degenerative osteoarthritis of the hip joint.
