Because arthritis in my hand and wrist the importance of wrist movement to hand function, Wrist Arthritis can have a serious effect on everyday activities.
Wrist Arthritis occurs most commonly in people aged over 45, but can occur earlier in those people who have sustained a broken wrist or a sprained wrist that causes wrist joint instability. To fully understand Wrist Arthritis it’s helpful to have a basic introduction to the anatomy of the wrist. The wrist is made up of a complex series of joints that are responsible for rotational, forward and back, and side to side movements of the wrist and hand. In the forearm, the joint between the Radius and Ulna bones is known as the Radio-Ulna joint.
The joint between the forearm and small bones of the wrist is known as the Radio-Carpal joint and the joints between the small bones of the wrist are known as the Carpal joints. Rotation of the wrist largely takes place at the forearm when the Radius rotates around the Ulna. Forward and back and side to side movements of the wrist largely take place at the Radio-Carpal and Carpal joints, although there is a combination of joint movements with all wrist motion. Styloid Tip of the Radius, then the joint between the Radius and the Scaphoid come into abnormal contact and become arthritic.
Wrist Arthritis may also occur subsequent to a wrist ligament injury. The initial trauma changes the mechanics of the wrist joints and sets off a process of progressive degeneration. The articular cartilage that covers the end of bones at the joints. It has a glassy, shiny appearance and is designed to allow friction free movement. The Hyaline cartilage is ultra smooth to allow friction free movement. However, early damage to the superficial layers produces a frayed appearance. In time, with more stress, this frayed surface evolves into cracks or ‘fissures’ in the articular cartilage, which can leave the underlying bone exposed to the point that there is bone on bone contact.
This causes inflammation of the wrist joint that is characterised by pain and swelling. Fragments of bone can become loose in the wrist causing locking or a restriction of wrist movement. Non traumatic conditions, such as Kienböck’s disease or Madelung’s deformity, can also lead to Wrist Arthritis. In Kienböck’s disease the Lunate bone ‘dies’ due to a lack of blood supply. The exact cause of Kienböck’s is unknown, but may be due to repetitive stress across the wrist during work activities.
