Joint injection of the wrist and hand region is a useful diagnostic and therapeutic tool for the family physician. In this article, the injection procedures for carpal tunnel syndrome, de Quervain's tenosynovitis, osteoarthritis of the first carpometacarpal joint, wrist ganglion cysts, and digital flexor tenosynovitis trigger finger are reviewed. Indications for carpal tunnel syndrome injection include median nerve compression resulting from osteoarthritis, rheumatoid arthritis, diabetes mellitus, hypothyroidism, repetitive use injury, and other traumatic injuries to the area. For the first carpometacarpal joint, injection may be used to treat pain secondary to osteoarthritis and rheumatoid arthritis. Pain associated with de Quervain's tenosynovitis is treated effectively by therapeutic injection.

In human anatomy , the wrist is variously defined as 1 the carpus or carpal bones, the complex of eight bones forming the proximal skeletal segment of the hand ; [1] [2] 2 the wrist joint or radiocarpal joint , the joint between the radius and the carpus [2] and; 3 the anatomical region surrounding the carpus including the distal parts of the bones of the forearm and the proximal parts of the metacarpus or five metacarpal bones and the series of joints between these bones, thus referred to as wrist joints. As a consequence of these various definitions, fractures to the carpal bones are referred to as carpal fractures, while fractures such as distal radius fracture are often considered fractures to the wrist. The distal radioulnar joint is a pivot joint located between the bones of the forearm , the radius and ulna.

Being a disease that primarily attacks synovial tissues, RA affects synovial joints, tendons, and bursae. Regarding disease detection, as the early RA manifestations are non-osseous in nature, ultrasound and MRI have shown to be superior to radiographs and CT. Plain radiography, however, remains the mainstay of imaging in the diagnosis and follow-up of RA 2.
