Abstract

The invention relates to an implant for the osteosynthesis of an osteotomy close to the base of a metatarsal, in particular the first metatarsal. The implant is longitudinal and long enough to insert the ends thereof into the marrow of the bone fragments (4, 6) to be joined, and for the ends of the implant to have means for fixing to the bone fragments (4, 6). The implant (2) can be inserted through a small cut in the skin and does not extend to the exterior of the bone fragments (4, 6).

Description

Implantat zur Osteosynthese einer basisnahen Osteotomie eines Mittelfußknochens Implant for osteosynthesis of a basal osteotomy of a metatarsal bone
Die Erfindung betrifft ein Implantat der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to an implant referred to in the preamble of claim 1 Art.
Die basisnahe Osteotomie ist eine chirurgische Operationstechnik zur Behandlung von Vorfußdeformitä- ten, meist Hallux valgus . Bei der aufklappenden Osteotomie wird der Knochen inkomplett quer zur Achse durchtrennt und unter Erhalt der fibularen Cortikalis aufgespreizt, um dadurch eine Achskorrektur vorzunehmen. Bei der zuklappenden Osteotomie wird ein Teil aus dem Kno- chen herausgenommen und die Osteotomie dann geschlossen. Bei schweren Ausprägungen der Erkrankung ist es notwendig, die basisnahe Osteotomie mit einer körperfernen Osteotomie des ersten Mittelfußknochens zu kombinieren (Doppelosteotomie) . Die heute gängigen Osteosyntheseverfahren der basisnahen Osteotomie umfassen Versorgungen ohne Implantate mit Schrauben oder mit von außen an den Knochen anzubringenden winkelstabilen oder nicht winkelstabilen Platten. Die Versorgung ohne Implantat hat eine aufwendige Nachbehandlung zur Folge, während die Schrauben- bzw. Plattenosteosynthese einen verhältnismäßig langen Haut- schnitt von ca. 7 bis 9 cm bedingt.Basal osteotomy is a surgical technique used to treat forefoot deformities, usually hallux valgus. In the unfolding osteotomy, the bone is incompletely transected transversely to the axis and spread to obtain the fibular Cortikalis, thereby making an Achskorrektur. When the osteotomy closes, one part is removed from the bone and the osteotomy is then closed. In severe cases of the disease, it is necessary to combine the basal osteotomy with a distal osteotomy of the first metatarsal bone (double osteotomy). Today's common osteosynthesis methods of basic osteotomy include restorations without implants with screws or with externally fixed to the bone to be fixed angle or non-stable plates. The treatment without an implant results in a complex post-treatment, while the screw or plate osteosynthesis requires a relatively long skin incision of about 7 to 9 cm.
Ziel der Erfindung war es, eine möglichst früh nach der Operation belastbare Osteosynthesetechnik zur basisnahen Osteotomie des ersten Mitttelfußknochens einzuführen. Dabei sollte der operative Zugang (Hautschnitt) möglichst klein gehalten werden.The aim of the invention was a as early as possible after surgery resilient osteosynthesis for basic osteotomy of the first metatarsal bone. In doing so, the operative access (skin incision) should be kept as small as possible.
Der Erfindung liegt die Aufgabe zugrunde, erst- malig ein Implantat zu schaffen, das bei der Osteosynthese eines Mittelfußknochens einsetzbar ist.The invention is based on the object of providing an implant for the first time which can be used in the osteosynthesis of a metatarsal bone.
Mittels der Erfindung kann die basisnahe Korrek- turosteotomie des ersten Mittelfußknochens über kleine Hautschnitte durchgeführt werden. Über einen ca. 2 cm langen Hautschnitt am Mittelfußköpfchen erfolgt zuerst die Abtragung der Pseudoexostose . Hierdurch wird der Markraum eröffnet. Über einen zusätzlichen, ca. 1 cm langen, Hautschnitt an der Basis des ersten Mittelfußknochens wird dann die basisnahe Osteotomie angelegt. Das erfindungsgemäße Implantat wird in den Markraum eingebracht und über ein Zielgerät durch die bestehenden Zugänge oder zusätzlichen Stichinzisionen mit Schrauben verriegelt. Dabei wird (werden) zuerst die proximale (n) Schraube (n) eingebracht. Als nächstes er- folgt das Einbringen der distalen Schraube. Das oval geformte distale Loch erlaubt das Anbringen einer Kompression auf den Osteotomiespalt , indem eine Madenschraube von distal in das Implantat geschraubt wird. Die Kompression wird dann durch Einbringen der mitt- leren Schraube gehalten. Die Madenschraube kann entfernt werden und die distale Schraube ebenfalls endgültig festgedreht werden.By means of the invention, the near-thoracic correction osteotomy of the first metatarsal bone can be performed via small skin incisions. About a 2 cm long skin incision on the metatarsal head, the ablation of pseudoexostosis is first carried out. This opens the medullary canal. About an additional, about 1 cm long, skin incision at the base of the first metatarsal bone then the base-near osteotomy is created. The implant according to the invention is introduced into the medullary cavity and locked via a target device through the existing access or additional Stichinzisionen with screws. The proximal screw (s) are first inserted. The next step is the insertion of the distal screw. The oval-shaped distal hole allows compression to be applied to the osteotomy gap by screwing a grub screw distally into the implant. The compression is then held by inserting the middle screw. The grub screw can be removed and the distal screw also tightened.
Bei Bedarf wird zusätzlich eine distale Osteotomie der Metatarsale 1 angelegt. Anhand der Zeichnung soll die Erfindung an einem Ausführungsbeispiel näher erläutert werden.If necessary, a distal osteotomy of the metatarsal 1 is additionally created. Reference to the drawing, the invention of an exemplary embodiment will be explained in more detail.
