ALTERNATIVE FIXING OF THE ARTHRODESIS OF HALLUX'METATARSOPHALANGEAL JOINT

Abstract:

The purpose of this paper is to demonstrate that fixing the hallux'metatarsophalangeal (MTP) arthrodesis by means of a 2-mm titanium plate and an inter-fragmentary compression screw is a feasible alternative that turns out to be as resistant as, or even more resistant than, the one obtained by using a 3.5-mm steel plate and an inter-fragmentary screw. In order to accomplish this objective, fourteen polymethyl-metac-rylatebone models of the hallux'MTP joint provided by Synbona were used. The articular surfaces of the proximal phalange were cut parallel to the articular surface and the head of the first metatarsal bone, in a dorsal angle of 10. Then, models were divided into two groups of 7 samples each. Samples in Group A were fixed with an inter-fragmentary screw and a 3.5-mm steel plate (Synthes®, and those in Group B were fixed using an inter-fragmentary screw and a 2-mm titanium plate (Synthes®. A pure …
