A solidifying prepolymeric implant composition comprising a biocompatible prepolymer and an optional filler. One such implant composition is a polyurethane implant composition comprising an isocyanate, such as hydroxymethylenediisocyanate (HMDI) and an alcohol, such as polycaprolactonediol (PCL diol). The compositions of the invention are useful for improving bone structure in patients by applying the solidifying implant composition to bone, reinforcing bone structure, improving load bearing capacity and/or aiding healing of microfractures.

A method of making a hydroxyl-terminated thioketal diol is provided, the method comprising reacting a thioketal ester with a non-pyrophoric reducing agent to form a hydroxyl-terminated thioketal diol. The hydroxyl-terminated thioketal diol can be 2,2-(propane-2,2-diylbis(sulfanediyl)) diethanol. The non-pyrophoric reducing agent can be a sodium aluminum hydride, for example, sodium bis (2-methoxyethoxy)aluminum hydride. The thioketal ester can be dimethyl 2,2-(propane-2,2-diylbis(sulfanediyl)) diacetate. A biodegradable matrix prepared by reacting a hydroxyl-terminated thioketal diol with an isocyanate is provided. A method of making a biodegradable polyurethane composite is also provided.
