Abstract

Mallet injuries are treated surgically when conservative treatment fails to achieve the optimum outcome. Tenodermodesis without K wire fixation is a simple and safe surgical option for the management of acute and chronic Mallet injuries.
This study aims to assess the functional outcome of Mallet injuries treated with Tenodermodesis.
Eight patients were treated with Tenodermodesis in our centre over a period of 45 months for Mallet injury. Seven cases had closed injury, and one patient suffered an open Mallet injury. Closed injuries had Tenodermodesis following failed conservative treatment. The open injury was treated with wound debridement and Tenodermodesis as an emergency procedure. All patients were assessed with Quick DASH score for functional outcome along with patient satisfaction.
In our series, we lost two patients in follow up. Mean follow up was four months (range 2 - 8 months). Five patients were satisfied with the outcome of the technique. One patient has superficial wound infection, and one had arthrodesis of distal interphalangeal joint because of persistent extension lag at distal interphalangeal joint. Average Quick DASH score was 7.20 (range 2.27 - 13.64). We achieved a good functional outcome in our series with Tenodermodesis for the management of Mallet injury. There were no significant complications noted using this technique.
