ABSTRACT:
Processes are set forth for forming high strength thermoplastic polymer bone fixation devices used, for example, in orthopedic surgery, where "strength" is quantified in terms a given device's pullout strength, tensile modulus, shear strength and breaking torque strength. Products of the aforementioned process are contemplated by the invention as well, with both "bioabsorbable" devices, for example, screws which are absorbable in an animal body and do not need to be removed after the bone in which they are inserted has healed; and non-bioabsorbable devices being described.
