New Endolog tool and you will surgical processes
New Endolog, produced as 2006 by Medical2, Castelnuovo del Garda, Verona, Italy, is a curved titanium endomedullary nail tool (TA6V ELI – ASTMF 136), addressed with anodic oxidization and laserlight marking. It is designed of the a curvilinear cylindrical looks that have an excellent diameter out-of 4.5 mm and you will a blade inclined by the cuatro° according to axis of your nail, and therefore provides to push for lateral interpretation of your own metatarsal lead.

It is fixed towards the metatarsal lead playing with an excellent 3.66-mm titanium angular stable bang, obtainable in three additional lengths (fifteen, 20, and you can 25 mm), and that stabilizes the latest osteotomy edges therefore the translation of your metatarsal head (Fig. 1). The term Endolog are created by the inventor Giuseppe Lodola that have mention of the endomedullary component of the fresh complete (Endo) along with his very own initials (Lo-G). It’s provided with devoted products that come with a keen impactor which have another drill book, about three attempt items of complete, a finished exercise tip, and an effective screwdriver. These features allow the equipment restrict biocompatibility, zero interference in case there is MR examine data, absolute sterility, traceability of your system, and you can adherence with the European legal rules (CE).

A tourniquet was applied and you can left in position within height of your own ankle. A beneficial cuatro-cm dorsal-medial longitudinal cut was created at a place corresponding to new exostosis of one’s earliest metatarsal, avoiding the dorsal digital department of one’s medial cutaneous will, plus the neurovascular bundle is secure correctly. After that, the fresh capsular incision was performed for the a good dorsal longitudinal orientation with each other the new distinct the skin incision. Capsular and you can ligamentous tissues https://fetlife.reviews/ethiopian-personals-review/ was in fact freed around the earliest metatarsal head dorsally and you can medially, additionally the bone was liberated on periosteum.

The fresh new oblique exostosectomy is through with a thickness of zero more 2–4 mm on distal the main medial eminence, nearby the articular skin, in order to no from the quantity of the new metatarsal neck, and come up with a lateral translation of lead you’ll be able to, pressed and you may maintained of the complete following its app, and you can repairing both the DMAA together with dislocated sesamoid methods due so you can pronation of one’s big bottom for the pursuing the derotation from the fresh metatarsal lead (Fig 3a, b). For this specific purpose, two 1.8-mm Kirschner wires, becoming joysticks, was in fact registered to allow the new derotation of one’s metatarsal lead throughout the the lateral translation. Good linear osteotomy, in certain cases perpendicular to the proximal level of the latest shoulder and you will some times oblique so you’re able to lengthen or perhaps to reduce new metatarsal, is actually performed (Fig. 2b). While the trial Endolog product try put together for the impactor, it was lightly lead to your medullary cavity which have increasingly horizontal displacement of one’s head and you will modern derotation of your own metatarsal lead, making use of the K-wires eg joysticks and fixing the newest DMAA and sesamoid subluxation (Fig. 2c).
