About HydroSpine

Hydrospine was formed in 2005 as a spin-off of Cambridge Polymer Group, Inc., who licensed several
hydrogel inventions to Hydrospine for spine applications.
 
Cambridge Polymer Group  is a contract research laboratory with over 20 years
of experience in polymer formulation, analysis, and test design. CPG has licensed instrumentation
and material technologies to companies including Zimmer, Biomet, and Thermoelectron.
Management Team
Stephen Spiegelberg, Ph.D.
Steve is the President of Cambridge Polymer Group, and has over 10 years of experience in analytical characterization of materials. He has a Ph.D. in Chemical Engineering from MIT. He has designed test methodologies and processing steps for the crosslinked polyethylenes used in hip and knee replacements, and holds several patents in highly crosslinked polyethylene formulations for orthopaedic applications. Steve also holds patents in instrumentation and surgical procedures for bone cement use. He chairs several ASTM task forces on characterization of materials for medical applications.
