Arthrodesis of the interphalangeal joint of the thumb is a widely performed procedure in hand surgery.
The most common indication is degenerative arthritis and occasionally post traumatic or inflammatory arthritides.
A variety of other indications exist. These include severe articular disruption from trauma, irreparable tendon injury, loss of function from neurological conditions and reconstruction following tumour resection.
A range of techniques have been described to fuse the interphalangeal joint of the thumb. These include dorsally placed low profile plates and intramedullary compression screws. Each technique has its unique advantages. Fusion rates overall are reported at 80-100%. Tension band wiring is a tried and tested, cost effective method that that remains in wide use today. The principle of tension band wiring is to convert a distracting force into a compressive one.
Most fusions of the thumb interphalangeal joint are set at between 0-30 degrees. It is important to come to an agreement with the patient after consideration of their occupation and desired function. In this example case, the patients unique functional needs demanded that his joint be fused in a degree of flexion that would be difficult to achieve with an intramedullary device.

- The vast majority of operations have a 10-15 MCQ quiz covering all aspects of the decision making and the technique
- There are four possible answers of which one is correct (or on occasion more correct) than the others.
- There are additional quiz modules on the surgical steps, the implants and problem cases being added continually
- The course is completed once all the lessons are read and quizzes submitted and passed.
- On successful completion of each quiz you will receive validated CPD points that add to the certificate in your CPD folder.
- Your dashboard also will contain a record of the time you have spent logged onto and using the site.
- The timer suspends after 5 minutes though if there is no activity.
