Joint stiffness

Introduction Joint stiffness refers to different degrees of obstacles in normal joint function (such as flexion and extension, rotation, etc.), which is manifested by a reduction in the range of motion. It is very different from a joint that has completely lost function. Joint stiffness can be caused by long-term plaster fixation, incorrect steel needle internal fixation, and internal fixation of the steel plate. The wounds of the operation, the lack of timely treatment after the bruise, the swelling, and the lack of timely exercise after the fracture healing are the main culprit for the joint stiffness.

Cause

Joint stiffness may occur during joint inflammation or joint inflammation caused by trauma, and morning stiffness caused by rheumatoid arthritis, joint stiffness, joint stiffness caused by osteoarthritis, and joint adhesion caused by long-term joint braking Etc., traumatic arthritis, joint swelling and stiffness can cause joint stiffness. The main pathological change is that when the injured limb is fixed for a long time without paying attention to functional exercise, the venous blood and lymph fluid will not flow well, and the joint tissue will be fibrotic.

1. Ask about the treatment of fractures.

2. Check the active and passive range of joints and record the degree of muscle atrophy and muscle strength.

3. X-ray examination: the former joint space is normal or slightly narrow, the latter joint space is narrow, the articular surface is rough, the bone density is increased or there is bone inflammation such as bone hyperplasia.

Differential diagnosis

When the injured limb is fixed for a long time without paying attention to functional exercise, the venous blood and lymph fluid will be poorly flown, and there will be fibrous fibrous exudation and fibrin deposition in the limb tissue, which may cause fiber adhesion in the internal and external tissues of the joint. At the same time, the joint capsule and the surrounding muscle contracture, joint activities can have different degrees of obstacles.
