Abstract
Abstract A graft fixation device combination. The device is useful for affixing a tissue graft to a bone or other body surface. The combination has a fixation device having two implantation members connected by a connecting member. The connecting member has at least one lateral wing member extending therefrom. The implantation members have longitudinal passageways therethrough. The combination also has an insertion member in engagement with the distal end of each implantation member.
