Abstract: An adjustable spring-loaded splint comprising a pair of lower struts and a pair of upper struts, each member of the pair of lower struts being pivotably connected to a member of the pair of upper struts, said members of each pair being spaced apart a distance to accommodate limb parts distal and proximal to the limb joint, at least one of said struts having at one end a pivotably mounted head portion defining a cam surface, an adjustable spring means mounted within the strut pivotably connected to said cam surface-containing strut and biased into engagement with said cam surface, for applying a quantifiable force tending to align or approximate the cam surface-containing strut with the adjustable spring means and means provided said pair of upper struts and said pair of lower struts for securely holding therebetween said distal and proximal parts of a limb.
