Stack Fingersplint from Dr. Paul Koch
Tendon-injuries of phalanges are treated with Stack's splints in conservative therapy.
The principal of Stack's splints is based on hyperextension of the injured phalanx. Fixation occurs with band-aid strips or velcro, and so guarantees secure fit.
It consists, among other things, of a thermoplastic acrylic resin plastic, which is perforated multiple times for improvement of wearing-properties, and therefore counter-acts skin macerations. This material can be formed over a flame ( bunsen-burner, etc. ) and also in hot water.
The cap over the phalanx media can be affixed with velcro or band-aid strips.
Even with multiple improvements to the splints, it is recommended to at least cover the injured finger with a tube bandage. Even better is covering the splint with a thin felt-layer, to prevent skin maceration.
