Practical Techniques to Ensure Success in Digital Ring Avulsion Injuries.

A ring avulsion results from a longitudinal traction to a digit. We discuss practical microsurgical techniques essential in achieving good functional outcomes in these challenging cases, including aggressive debridement of the affected tissues and vessels, liberal use of vein grafts and arterialized venous flow through flaps when needed, and a meticulous microsurgical technique. We have found that patient selection is key in digit salvage and a good outcome is often achieved with the winning triad of optimal patient factors, surgical factors, and intensive hand therapy. We also include a case performed by our senior author to illustrate what can be achieved.
