Joint stiffness

Introduction Ankylosis of the joint is taken as an example of knee ankylosis. It can cause internal adhesion of the knee joint due to rheumatoid arthritis of the knee joint, fracture, hemorrhage, long-term brake and synovial resection. It loses active and passive activities and is called knee ankylosis. Knee ankylosis can be divided into straight-type ankylosis and flexion-type ankylosis, of which the straight type is more common. For example, long-term plaster fixation, incorrect steel needle internal fixation, and internal fixation of the steel plate can cause joint rigidity. The wounds of the operation, the lack of timely treatment after the bruise, the swelling, and the timely exercise after the fracture healing are the main culprit for the joint stiffness.

Cause

The causes of joint stiffness are summarized as:

Bacterial: joint stiffness caused by septic arthritis, bone tuberculosis, etc.

Asepticity: such as long-term plaster fixation, incorrect steel needle internal fixation, and internal fixation of the steel plate can lead to joint stiffness. The wounds of the operation, the lack of timely treatment after the bruise, the swelling, and the timely exercise after the fracture healing are the main culprit for the joint stiffness.

Joint stiffness is generally insidious, with no clinical symptoms in the early stage. Some patients may show mild systemic symptoms in the early stage, such as fatigue, weight loss, long-term or intermittent low fever, anorexia, mild anemia. Due to the mild condition, most patients can not be detected early, resulting in delayed disease and loss of optimal treatment timing.

(1) Low back pain, waist stiffness for more than 3 months, can not be relieved by rest.

(2) Unilateral or bilateral sciatica, no history of obvious trauma or sprain.

(3) recurrent episodes of knee or ankle joint swelling and pain, joint effusion, no history of obvious trauma, history of infection.

(4) recurrent episodes of calcaneal tuberosity swelling or heel pain.

(5) There are no respiratory symptoms such as cough, chest pain and banding without history of trauma, and thoracic activity is limited.

(6) Spinal pain, stiffness, and even limited mobility, no history of trauma or sprain.

(7) Pain in both hips and hips, no history of obvious trauma and history of strain.

(8) sudden onset of pain in the spine and extremities, swelling, and dysfunction of activity.

Differential diagnosis

Rheumatoid arthritis: often involving the wrist joint and the proximal interphalangeal joint, the early general does not involve the distal interphalangeal joint. In order to facilitate the young doctors to master the clinical features of rheumatoid arthritis, we often refer to these three groups of joints in teaching. It is the "target joint" of rheumatoid arthritis, because more than 90% of rheumatoid arthritis may involve at least one group of these three groups of joints sooner or later.

Osteoarthritis: The osteoarthritis of the finger mainly involves the distal interphalangeal joint (Heberden nodule), the proximal interphalangeal joint (Bouchard nodule) or the first carpometacarpal joint; rarely involving the metacarpophalangeal joint and the entire wrist joint . The affected interphalangeal joints showed nodular changes on both sides of the back of the joint.

Psoriatic arthritis: It is also often involved in the distal interphalangeal joint, but it is often accompanied by periungual skin or nail damage. The whole body skin is more or less able to find typical silver. Scab skin changes.
