It’s fixed towards the metatarsal head playing with good step three.66-mm titanium angular secure bang, found in three other lengths (fifteen, 20, and you may twenty-five mm), and therefore balances the osteotomy edges in addition to interpretation of the metatarsal head (Fig. 1). The expression Endolog try coined by the its maker Giuseppe Lodola having reference to the endomedullary component of the brand new complete (Endo) and his awesome own initials (Lo-G). It’s provided by devoted instruments that include an impactor with a separate bore guide, about three decide to try types of your complete, a finished exercise tip, and good screwdriver. These features give the product restriction biocompatibility, zero interference in the event of MR test research, sheer sterility, traceability of your system, and you may adherence into Eu court regulations (CE). So far as we are aware, not any other available product has got the book tech functions for the complete, besides the ancestor of your own Endolog, new “hallux splint” .

A beneficial tourniquet was used and you may kept positioned at the level of your foot. An excellent 4-cm dorsal-medial longitudinal incision is made from the a point equal to the new exostosis of one’s first metatarsal, steering clear of the dorsal digital department of medial cutaneous will, in addition to neurovascular bundle are secure correctly. Upcoming, the newest capsular cut is actually performed inside the a beneficial dorsal longitudinal orientation along new collection of your skin incision. Capsular and you will ligamentous frameworks were freed within the earliest metatarsal lead dorsally and you may medially, plus the bone is liberated on periosteum.

A beneficial linear osteotomy, in certain cases perpendicular towards proximal amount of the new neck and you may from time to time oblique so you’re able to lengthen or to shorten the brand new metatarsal, was did (Fig

Playing with a fundamental oscillating spotted within the a distal so you can proximal guidelines, an incredibly limited, oblique exostosectomy was did to eradicate new medial eminence and generate an apartment surface for the lead to service new impactor’s knife upon which the computer is actually assembled (Figs. 2a and you can 3a, b). To have a correct updates of your equipment, perfect coplanarity and limitation adherence of one’s pallet help with the flat working surface in the past authored into the metatarsal lead is extremely important (Fig. 3c). The newest oblique exostosectomy are finished with a thickness out of zero more dos–4 mm regarding the distal area of the medial eminence, close to the articular facial skin, to no at number of brand new metatarsal neck, and make a lateral interpretation of one’s direct you can, forced and handled from the nail as a result of its app, and correcting both DMAA and dislocated sesamoid apparatus due so you’re able to pronation of the larger toe in adopting the derotation away from the metatarsal head (Fig 3a, b). For this purpose, two 1.8-mm Kirschner wires, becoming joysticks, was basically registered so that this new derotation of the metatarsal lead through the its horizontal translation. 2b). Since demo Endolog tool is developed into the impactor, it absolutely was carefully put towards the medullary hole which have increasingly lateral displacement of head and you will modern derotation of the metatarsal direct, with the K-wires eg joysticks and you can repairing new DMAA and sesamoid subluxation (Fig. 2c).
