processes are set forth for forming high strength thermoplastic polymer bone fixation devices used , for example , in orthopedic surgery , where &# 34 ; strength &# 34 ; is quantified in terms of a given device &# 39 ; 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 &# 34 ; bioabsorbable &# 34 ; 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 .
