General Issues

SSA Listing 1.02 Major dysfunction of a joint(s)

“1.02 Major dysfunction of a joint(s) (due to any cause): Characterized by gross anatomical deformity (e.g., subluxation, contracture, bony or fibrous ankylosis, instability) and chronic joint pain and stiffness with signs of limitation of motion or other abnormal motion of the affected joint(s), and findings on appropriate medically acceptable imaging of joint space narrowing, bony destruction, or ankylosis of the affected joint(s). With:
A. Involvement of one major peripheral weight-bearing joint (i.e., hip, knee, or ankle), resulting in inability to ambulate effectively, as defined in 1.00B2b;


“B. Involvement of one major peripheral joint in each upper extremity (i.e., shoulder, elbow, or wrist-hand), resulting in inability to perform fine and gross movements effectively, as defined in 1.00B2c.”

Lets take a look into the meaning of the listing with examples and definations.

Subluxation means a joint moves out of alignment. If the joint is not stabile the joint will not maintain alignment.

Ankylosis means fixation or joint does not move. A joint with advanced arthritis may fuse the joint together the joint will no longer move.  When the joint fuses it is known as bony ankylosis.  The joint could also be fused by fibrous ankylosis.  In this case the joint is fixed because the tissues (ligaments, tendons, skin) has hardened around the joint.  Bony ankylosis will eventually result in an fibrous ankylosis.  Although, you can have one without the other.

For part B of the listing the inability to perform fine and gross movements effectively means an extreme loss of function of both arms.  This part of the listing requires a very serious problem doing tasks and completing tasks by yourself.  Using your arms effectively means you are capable of  reaching, pushing, pulling, grasping, and fingering on a  sustained basis.  SSA will look at your ability to perform activities of daily living. See our pervious blog for information on activities of daily living.
