Abstract

The implant has a clamping device for spreading a foot approaching osteotomy, and a target device for setting screws. The surgical implant is inserted in a mark space and has a round, oval or semicircular or semi oval plate-like cross section.

Description

Die basisnahe Osteotomie ist eine chirurgische Operationstechnik zur Behandlung von Vorfußdeformitäten, meist Hallux valgus. Bei schweren Ausprägungen der Erkrankung ist es notwendig, die basisnahe Osteotomie mit einer körperfernen Osteotomie des ersten Mittelfußknochens zu kombinieren (Doppelosteotomie).The Basic Osteotomy is a surgical surgical technique for Treatment of forefoot deformities, mostly Hallux valgus. In severe forms of the disease it is necessary, the basal osteotomy with a distal osteotomy of the first metatarsal to combine (double osteotomy).

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.The today common Osteosynthesis methods of basic osteotomy include restorations without Implants, with screws or externally attached to the bone angularly stable or non-angularly stable plates.

Die Versorgung ohne Implantat hat eine aufwändige Nachbehandlung zur Folge, während die Schrauben- bzw. Plattenosteosynthese einen verhältnissmäßig langen Hautschnitt von ca. 7 bis 9 cm bedingen.The Supply without implant results in a complex post-treatment, while the screw or Plattenosteosynthese a comparatively long Skin incision of about 7 to 9 cm condition.

Ziel der Erfindung war es, eine winkelstabile, möglichst früh nach der Operation belastbare Osteosynthesetechnik zur Doppelosteotomie einzuführen. Dabei sollte der operative Zugang (Hautschnitt) möglichst klein gehalten werden.aim The invention was an angular stable, as early as possible after the operation resilient Osteosynthesis technique to introduce double osteotomy. The operative should be Access (skin incision) as possible kept small.

Mittels der Erfindung kann die Doppelosteotomie über zwei kleine Hautschnitte (1 bis 1,5 cm) durchgeführt werden. Über einen ca. 1,5 cm langen Hautschnitt am Mittelfußköpfchen erfolgt zuerst die körperferne Osteotomie (z.B. Chevron-Technik). 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. Die MMP wird mit oder ohne Aufbohren in den Markraum eingebracht. Die Osteotomie wird entweder mit Hilfe einer Spannvorrichtung (Variante 1) über die Platte oder konventionell aufgespreizt (Variante 2). Zur Fixierung werden mehrere winkelstabile Schrauben eingebracht.through The invention can double osteotomy over two small skin incisions (1 to 1.5 cm) performed become. about An approx. 1.5 cm long skin incision on the head of the metatarsus takes place first off the body Osteotomy (e.g., chevron technique). This opens the medullary canal. About one additional about 1 cm long, skin incision at the base of the first metatarsal bone Then the basal osteotomy is created. The MMP is using or introduced without drilling into the medullary canal. The osteotomy is either by means of a clamping device (variant 1) on the Plate or conventional spread (variant 2). For fixation Several angle stable screws are introduced.
