ABSTRACT:
The apparatus includes upper and lower pin holder assemblies of ring-like configuration which may be opened for application to the limb. Each pin holder assembly includes opposed wall structures within which bone penetrating pins are secured to firmly attach each pin holder assembly to the bone segment. Elongate connector assemblies extend between the upper and lower pin holder assemblies with each of the connector assemblies including spherical coupling components which permit adjustment of the pin holder assemblies in a universal manner. Each connector assembly includes nut elements which dually serve to position an intermediate spherical component along the connector shaft for locked engagement with the ring structure of a pin holder assembly.
