Wrist Ultrasound Scan
The Wrist Ultrasound
The bones of the hand and wrist provide the body with support and flexibility to manipulate objects in many different ways. Each hand contains 27 distinct bones that give the hand an incredible range and precision of motion. The forearm’s ulna and radius support the many muscles that manipulate the bones of the hand and wrist.
Although the anatomy of the hand and wrist is complex and the pathologic conditions encountered are diverse, many of the disease processes are localized, and in many situations, the clinical question is specific and limited. Because of this, ultrasound has always been an attractive imaging modality for evaluation of hand and wrist problems.
Specific situations in which ultrasound offers definite benefits include evaluation of tendon inflammation and rupture, evaluation of palpable masses or suspected occult masses, and evaluation of suspected foreign bodies.
Hand and wrist injuries are also common in athletes and can affect articular structures (ligaments, joint surfaces etc), periarticular tendons, muscles and nerves. These injuries can be acute or chronic. Acute injuries follow sudden traumatic events such as falls or joint sprains. Chronic lesions can be the result of local repetitive microtrauma or the sequelae of an acute injury.
What is the purpose of this ultrasound scan?
The purpose of this wrist scan is to provide an assessment of the musculoskeletal structures in the wrist join. They include:
- Carpal tunnel
- Ulnar nerve
- Distal radioulnar joint
- Midcarpal joints
- Trinagular fibrocartilage complex
- The six extensor compartments
- Abnormal fluid or inflammation around the wrist
Reasons for having a wrist scan include:
- Reduced Movement
- wrist effusion and/or synovial thickening (inflammatory/traumatic/septic)
- erosions from inflammatory arthropathy
- De Quervain tenosynovitis
- intersection syndrome
- carpal tunnel syndrome
- ganglion cysts
- tendinosis, partial thickness tendon tear, full thickness tendon tear
- scapholunate ligament injury
- TFCC injury
- avulsion injuries
What is included with this wrist ultrasound scan?
- Ultrasound report and if needed, a follow up recommendation.
Preparation for the wrist ultrasound scan
No preparation is necessary for this scan.
What should I expect during the wrist ultrasound scan?
Before the ultrasound scan our sonographer will explain the examination procedure. You will be asked to sit on a chair and expose your wrist. A small amount of gel will be placed on your wrist and the ultrasound probe will be moved in different directions. You may also be asked to move your wrist during the scanning so that the sonographer can look at the affected area while it is in motion.
During and after the examination our sonographer will explain the findings and an ultrasound report will be issued to take away with you.
