Description
Die Erfindung betrifft eine modulare Revisionspfanne für die Hüftgelenkendoprothetik und Verankerungszapfen hierzu.The The invention relates to a modular revision socket for hip arthroplasty and anchoring pin this.
[Stand der Technik][Was standing of the technique]
Beim Ersatz eines verschlissenen Hüftgelenkimplantats stellt der Operateur regelmäßig sowohl im Bereich des Hüftstieles als auch im Bereich der Hüftpfanne partiellen Knochenverlust fest. Der Operateur muss das Knochenbett für die Fixierung des Implantates unter Verlust von weiterer Knochenmasse vorbereiten und für die Revisionsimplantation eine Gelenkskonfiguration wählen, die die veränderten räumlichen Bedingungen berücksichtigt. Während für den Revisionsstiel bereits bewährte Lösungen existieren, ist dies für die Revisionspfannenprothese nicht der Fall bzw. die existierenden Lösungen sind unbefriedigend. Als wesentliche Anforderung ist insbesondere die variable und dennoch sichere, primär- und dauerstabile Verankerung der acetabulären Implantatkomponente, im folgenden Revisionspfanne genannt, im Beckenknochen bisher nicht zufriedenstellend gelöst.At the Replacement of a worn hip joint implant provides the surgeon regularly both in the Area of the hip stem as well as in the area of the hip socket partial bone loss. The surgeon needs the bone bed for the Fixation of the implant with loss of further bone mass prepare and for the revision implant will choose a joint configuration that the changed spatial Conditions taken into account. While for the Revision handle already proven solutions exist, this is for the revision cup prosthesis is not the case or the existing ones solutions are unsatisfactory. In particular, as an essential requirement the variable, yet secure, primary and permanent anchorage the acetabular Implant component, referred to in the following revision pan, in the pelvic bone so far not satisfactorily solved.
Zusätzlich muss die Revisionspfanne insbesondere bei Wechseloperationen aufgrund von Endoprothesenlockerungen mit schweren Schäden des Knochenlagers, z.B. nach Mehrfachwechseln, dem besonderen Anspruch genügen, auch regenerative Prozesse im umgebenden Knochenlager zu ermöglichen um damit eine hohe Sekundärstabilität zu realisieren.In addition, must the revision pan especially during replacement operations due of endoprosthesis loosening with severe damage to the bone stock, e.g. after multiple changes, meet the special requirement, too to enable regenerative processes in the surrounding bone stock to realize a high secondary stability.
Durch eine entsprechende Formgebung der Revisionspfanne muss sichergestellt sein, dass die Lage des Bewegungszentrums trotz des defekten Knochenlagers rekonstruiert wird und dass der Bewegungsumfang in weitgehend natürlichem Maße möglich sein soll.By a corresponding shape of the revision pan must be ensured be that the location of the movement center despite the defective bone stock is reconstructed and that the scope of motion in a largely natural extent be possible should.
Der Operateur stellt die Forderung, neben der unkomplizierten Handhabung der Revisionspfanne, in der konkreten operativen Situation variabel auf den vorgefundenen Befund, den unterschiedlichen Knochenverlust, reagieren zu können.Of the Surgeon makes the claim, in addition to the uncomplicated handling Revision panel, variable in a concrete operational situation on the found findings, the different bone loss, to be able to react.
Pfannen für die Hüftgelenkendoprothetik sind in verschiedener Ausführung bekannt. Durch ihre Form, ihre funktionellen Bereiche und durch ihre Zusatzelemente wird mit unterschiedlichem Erfolg versucht, die aufgezeigten Anforderungen auch für den Revisionsfall zu erfüllen.Pans for the Are hip arthroplasty in different design known. Through their shape, their functional areas and through their additional elements are tried with varying degrees of success to fulfill the indicated requirements also for the revision case.
Sie lassen sich grob in folgende Gruppen einteilen:
- – Hüftpfannen mit ovalärer Form
- – Hüftpfannen mit Lasche
- – Hüftpfannen mit Zapfen
- – Hüftpfannen mit Lasche und Zapfen
- – Hüftpfannen mit anderen Verankerungsmitteln
- - Acetabular cups with oval shape
- - acetabular cups with flap
- - acetabular cups with pegs
- - acetabular cups with lugs and spigots
- - acetabular cups with other anchoring means
Dabei ist die ovaläre Form besonders vorteilhaft, um den Knochenverlust, der in den typischerweise auftretendenden acetabulären Defekten offenbar wird, teilweise ausgleichen zu können.there is the oval Shape particularly beneficial to the bone loss that is typical in the occurring acetabular Defects apparently will be able to compensate in part.

Revisionspfanneimplantat wird in dem Gebrauchsmuster
Nachteil dieses Gelenkpfannenimplantates ist es, dass keine zusätzlichen Verankerungen zur Befestigung am Knochen vorgesehen sind und es somit als Revisionspfannenimplantat bei größeren Defekten, die nicht mit Pressfit-Implantaten versorgt werden können, nicht geeignet sind.disadvantage This acetabular implant is that no additional Anchors are provided for attachment to the bone and it thus as a revision socket implant for larger defects that are not with Press-fit implants can be supplied are not suitable.
Ein weiteres Problem besteht darin, dass das Revisionspfannenimplantat im Acetabulum mit dem patientenindividuell einzustellenden Pfanneneingangswinkel in die richtige Stellung gebracht werden muss, da ansonsten der Bewegungsumfang nach der Implantation eines künstlichen Hüftgelenkes nicht mehr physiologisch nachgebildet ist. Durch ein zu tiefes Einpressen des Implantats in das Acetabulum entsteht ein verändertes Rotationszentrum, wodurch die Beinlänge und der femurale Abstand negativ beeinflusst werden. Zur Verhinderung dieses zu tiefen Einpressens können am Revisionspfannenimplantat Befestigungslaschen vorhanden sein.One Another problem is that the revision cup implant in the acetabulum with the individual patient to be adjusted Pfanneneingangswinkel in the right position, otherwise the Range of motion after implantation of an artificial hip joint is no longer physiological is modeled. Due to too deep pressing in of the implant in the acetabulum creates an altered center of rotation, which the leg length and the femoral distance are negatively affected. To prevent this too deep pressing can Attachment tabs may be present on the revision socket implant.
In
dem Gebrauchsmuster
Die Lasche ist in einem festen Winkel mit der Pfanne verbunden. Dieser Winkel ist so gewählt, das er für eine empirisch ermittelte mittlere Beckenform optimal ist. Auf patientenspezifisch verschiedene Formen kann damit nicht reagiert werden oder es müssen in diesem Fall implantatbedingte, in der Regel abtragende Anpassungen des Knochenlagers vorgenommen werden.The Tab is connected at a fixed angle with the pan. This Angle is chosen he for an empirically determined middle pelvic form is optimal. On patient specific different forms can not be reacted or it must be in In this case, implant-related, usually ablation adjustments be made of the bone store.

Die erfindungsgemäße modulare Revisionspfanne besteht aus einem Pfannengrundkörper, einer Befestigungslasche, einem oder mehreren Verankerungszapfen und einem Pfanneneinsatz.The modular according to the invention Revision pan consists of a pan body, a fastening strap, one or more anchoring pins and a socket insert.
Der Pfannengrundkörper ist als ovaläre Pressfitschale geformt, deren Grundform durch Radien beschreibbar ist. Er weist einen Pressfitwinkel zwischen 75°-82° und eine breite Pressfitfläche auf, die im vorwiegend erhaltenen Defektbereich abgeflacht ist. Der Pfannengrundkörper hat zwei polyaxiale Spreizpressfitlager für Verankerungszapfen, ein Montagelager für eine Befestigungslasche und eine Aussparung zur Verhinderung des Anschlagens des Kopfhalses (Impingement) und konsekutiver Luxation des Kopfes.Of the Pan base is as an oval pressfit dish shaped whose basic shape is described by radii. He points a pressfit angle between 75 ° -82 ° and a wide pressfit surface on, which is flattened in the predominantly obtained defect area. The pan base body has two polyaxial expansion bearing blocks for anchoring pins, an assembly bearing for one Mounting tab and a recess to prevent the impact of the head neck (impingement) and consecutive dislocation of the head.
Die Befestigungslasche ist entsprechend den operativen Anforderungen in unterschiedlichen Geometrien einsetzbar. Die Aufnahme von Kippmomenten der Befestigungslasche erfolgt durch ein Befestigungslager im Pfannengrundkörper.The Fastening tab is according to the operational requirements can be used in different geometries. The absorption of tilting moments The fastening tab is made by a mounting bearing in the pan body.
Ein oder mehrere Verankerungszapfen können in verschiedenen Größen gesetzt werden, wobei die Verankerung im Grundkörper durch Spreizpressfit erfolgt. Der Verankerungszapfen wird mittels Führhülse durch eine Bohrung im Pfannengrundkörper gesetzt.One or more anchoring pins can be set in different sizes be anchored in the body by Spreizpressfit. The anchoring pin is set by means of a guide sleeve through a hole in the socket body.
Der Pfanneneinsatz wird durch Pressfit in der Pfanne befestigt. Auch er hat eine Aussparung zur Verhinderung von Impingement.Of the Cup insert is fixed in the pan by pressfit. Also He has a recess to prevent impingement.
Der Verankerungszapfen besitzt mehrere Funktionsbereiche. Der Spitzenbereich ist zylindrisch und dient zur Führung des Zapfens während des Eindrückens. Der Führungsbereich, welcher sich dem Spitzenbereich anschließt, ist kegelförmig polyedrisch ausgeführt und dient zur Verdrehsicherung und Kompression des spongiosen Knochens während des Einführens. Der darauf folgende Haltebereich besitzt die funktional gleich modifizierte Oberfläche wie der Pfannengrundkörper und sichert als bevorzugter knöcherner Einwachsungsbereich die mechanische Stabilität des Verankerungszapfens im Knochen. Der abschließende Kopfbereich ist dübelähnlich mit sphärischen Teilflächen aufgebaut. Er dient zur Befestigung des Verankerungszapfens in der Revisionspfanne und ermöglicht die polyaxiale Ausrichtung des Verankerungszapfens. Mit dem Kopfbereich sind Sicherungsnoppen verbunden, welche in Aussparungen des Zapfenlagers eingreifen und den Verankerungszapfen gegen Verdrehung sichern.The anchoring pin has several functional areas. The tip area is cylindrical and serves to guide the pin during indentation. The guide region, which adjoins the tip region, is designed conically polyhedral and serves to prevent rotation and compression of spongious bone during insertion. The following holding area has the same functionally modified surface as the pan base body and, as a preferred bony ingrowth area, ensures the mechanical stability of the anchoring pin in the bone. The final head area is dowel-like Lich built with spherical surfaces. It serves to fasten the anchoring pin in the revision socket and allows the polyaxial alignment of the anchoring pin. With the head area locking knobs are connected, which engage in recesses of the journal bearing and secure the anchoring pin against rotation.
Die kegelförmig polyedrisch ausgeführten Flächen des Führungsbereichs sind als Viererflächen oder Sternflächen ausgeführt.The conical polyhedral surfaces of the guiding region are as quadruplets or Stern faces executed.
Der Haltebereich besitzt eine osteointegrative Fläche, die durch Beschichtung oberflächenvergrößert ist und als Oberflächenabschluss eine bioaktive Calciumphosphat-Schicht aufweist.Of the Holding area possesses an osteointegrative area covered by coating surface is enlarged and as a surface finish a bioactive calcium phosphate layer.

Die Steigung der seitlichen Pfannenflächen in Bezug auf die Implantatgrundfläche ist mit einem Winkel zwischen 75°-82° so gewählt, dass ein belastbarer Halt nach dem Einpressen der Pfanne in ein intaktes Implantatlager (Pressfit im weiten Randbereich der Revisionspfanne) gegeben ist.The Slope of the side pan surfaces with respect to the implant base is with an angle between 75 ° -82 ° so chosen that a strong grip after pressing the pan into an intact Implant bearing (press fit in the wide edge area of the revision socket) given is.
Die
Kanten
Im Pfannengrundkörper befinden sich Öffnungen zur Aufnahme von konventionellen Knochenschrauben.in the Pan base there are openings for receiving conventional bone screws.
Für Defektsituationen,
bei denen das Implantatlager in Bezug auf die Primärstabilität nicht
hinreichend belastbar ist, werden zur Erhöhung der Primärstabilität, abgesehen
von konventionellen Knochenschrauben, die modular wählbaren
Teile Befestigungslasche
Die
Verankerungszapfen
Zur Sicherung des Einwachsens und zur Vergrößerung der osteointegrativen Oberfläche der Revisionspfanne wird die Pressfit-Seite des Implantats in einem ersten Schritt mit einer strukturierten Oberfläche versehen, die in einem weiteren Schritt osteoinduktiv beschichtet wird. Die Strukturierung erfolgt indirekt durch Aufrauhung mittels Abrasionsstrahl und nachfolgender Oberflächenvergrößerung durch Aufbringen von Ti-Partikeln in einem plasmagestützten Beschichtungsprozess. Die osteoinduktive Beschichtung erfolgt durch elektrochemische Abscheidung einer biomimetischen Calciumphosphatschicht (z.B. mit BONIT®).To ensure the ingrowth and increase of the osteointegrative surface of the revision socket, the pressfit side of the implant is provided in a first step with a structured surface, which is coated in an osteoinductive manner in a further step. The structuring takes place indirectly by roughening by means of abrasion jet and subsequent surface enlargement by application of Ti particles in a plasma-assisted coating process. The osteoinductive coating is done by electrochemical deposition biomimetic calcium phosphate coating (eg with BONIT ®).
