A trigger finger is a common disorder of later adulthood characterized by catching, snapping or locking of the involved finger flexor tendon, associated with dysfunction and pain. In the video above hand surgeon Dr. Neema Amin (John Randolph Medical Center) describes treatment options and when to seek medical attention when the trigger finger gets more frequent or painful.

What causes trigger finger – a.k.a. stenosing tenosynovitis?

Causes for this condition are not always clear. Some trigger fingers are associated with medical conditions such as rheumatoid arthritis, gout, and diabetes. Local trauma to the palm/base of the finger may be a factor on occasion, but in most cases there is not a clear cause.

A French scheme of the 1998 first hand transplant in the world.

In 1998 surgeons in France have carried out the world’s first hand transplant. In 1998 the transplanted hand came from an anonymous dead donor and was grafted onto the right arm of 45-year-old Clint Hallam, an Australian whose own hand was amputated in 1984 after an accident.

In april 2009 the 6th hand transplant in the US (the 40th in the world) was performed on a Marine combat engineer who lost his hand during the war in Iraq: on Jan. 31, 2007, while holding a quarter-stick of TNT in his right hand when it accidentally exploded. The transplanted hand came from an 18-year-old West Virginia man who died of head trauma.


The benefits of a hand transplant can very significant, but these advances are not very well described and rated yet. However, the rejection risk (the body may ‘reject’ the new hand) and ethical concerns still make it a touchy issue.

Likely, what is needed is a controlled study comparing hand transplant recipients and prosthetics users of a hand prosthesis on various tasks, including quality-of-life measurements.

• Dr. Joseph Imbriglia (hand surgeon) says:

“The prostheses become more of a burden than not, and the reason is that they have no sensation.”

• MD. John D. Lantos (bioethicist) says:

“You could look at such things as, can they pick up a penny, can they hold a pencil, can they eat with a spoon or play a piano – you can imagine hundreds of things you could measure with the two groups where you could say in these domains transplant patients are doing as well, or worse or better. And then you’d have the possibility for truly informed procedures.”
