Accessory bones of the ankle. [13]Accessory bones at the ankle mainly include: Os subtibiale, with a prevalence of approximately 1%. [14] It is a secondary ossification center of the distal tibia that appears during the first year of life, and which in most people fuses with the shaft at approximately 15 years in females and approximately 17 years in males.
Carpometacarpal bossing (or metacarpal/carpal bossing) is a small, immovable mass of bone on the back of the wrist. The mass occurs in one of the joints between the carpus and metacarpus of the hand , called the carpometacarpal joints , where a small immovable protuberance [ 1 ] occurs when this joint becomes swollen or bossed.
When the X-ray is diagnostic and there is a convincing Terry Thomas sign it is a static scaphoid instability. When the scaphoid is made unstable by either the patient or by manipulation by the examining physician it is a dynamic instability. [11] SNAC. In order to diagnose a SNAC wrist you need a PA view X-ray and a lateral view X-ray.
X-ray of trapeziometacarpal joint replacement. Left hand of a 58-year-old woman. The joint can be replaced with artificial material. An artificial joint is also referred to as a prosthesis. Prostheses are more problematic at the trapeziometacarpal joint compared to joints like the knee or the hips.
The initial treatment for both traumatic and degenerative TFCC lesions, with a stable DRUJ, is conservative (nonsurgical) therapy. Patients may be advised to wear a temporary splint or cast to immobilize the wrist and forearm for four to six weeks. [10] The immobilization allows scar tissue to develop which can help heal the TFCC.
The PA wrist x-ray will demonstrate sclerosis and joint space narrowing between the lunate and capitate. Over time, the capitate will migrate proximally into the space created by the scapholunate dissociation. [2] The radiographic findings in Stage III SLAC wrist are synonymous with the Terry-Thomas sign, indicating complete scapholunate ...
X-ray images indicate scapholunate ligament instability when the scapholunate distance is more than 3 mm, which is called scapholunate dissociation. [7] A static scapholunate instability is generally readily visible, but a dynamic scapholunate instability can only be seen radiographically in certain wrist positions or under certain loading conditions, such as when clenching the wrist, or ...
If x-ray results show arthritis due to an old break, the treatment plan will first focus on treating the arthritis through anti-inflammatory medications and wearing a splint when an individual feels pain in the wrist. If these treatments do not help the symptoms of arthritis, steroid injections to the wrist may help alleviate pain.
