Customizable Hyperextension Splint for Mallet Finger

Abstract

Introduction: Mallet finger is a common deformity occurring due to the traumatic detachment of the extensor tendon at its insertion in the distal phalanx. Despite several different methods of splinting being available, residual extensor lag remains one of the most common complications of conservative treatment. Technique Report: We demonstrate a novel technique to make a hyperextension splint which can be customized as per the individual. The pictorial demonstration depicts every step in the preparation, application, and maintenance of the splint. Conclusion: We believe that the use of such easily accessible materials and visual demonstration of each step, with pointers along the way to verify the correct technique, will empower any medical professional, to satisfactorily treat such injuries at the primary point of contact, without necessitating the services of a hand surgeon. Keywords: Mallet finger, splint, thermoplastic.
