[Unilateral mandibular fracture in horse – Treatment with fixateur externe, a complication during implant removal and procedure for removal of implant fragments].
Abstract: The first part of this case report describes the surgical treatment of a unilateral mandibular fracture in the standing horse by using a fixateur type I. By the time of implant removal, the fracture had completely healed. However, during implant removal, an implant failure of 2 of the 4 implants occurred with fragments remaining in the bone. The second part of the report focuses on the development of a special surgical instrument that was designed for removal of the implant fragments. Furthermore, the surgical method allowing the entire extirpation of the fragments within a second surgery is described.According to the authors' knowledge, this is the first case report showing the use of the presented surgical technique for the treatment of a mandibular fracture in the standing horse. Additionally, this report also provides an approach for removing implant fragments from the depth of the bone which may occur in case of implant breakage as a potential complication of the described surgery. Der vorliegende Fallbericht beschreibt im ersten Teil die chirurgische Versorgung einer unilateralen Mandibulafraktur mittels eines Fixateur externe Typ I am stehenden Pferd. Nach vollständiger Abheilung der Fraktur kam es während der Implantatentfernung zum Bruch von 2 der 4 Implantate mit Verbleib von Fragmenten im Knochen. Im zweiten Teil des Berichts wird ein spezielles Instrument beschrieben, das zur Entfernung der Implantatfragmente konzipiert und angefertigt wurde. Zudem wird die chirurgische Technik, welche die vollständige Entfernung in einer zweiten Operation ermöglichte, dargestellt.Nach dem Wissen der Autoren handelt es sich bei diesem Fallbericht um die erste Beschreibung der Versorgung einer Mandibulafraktur mit der hier vorgestellten Technik am stehenden Pferd. Zusätzlich liefert dieser Bericht auch einen Lösungsansatz zur Bergung von tiefgelegenen Implantatfragmenten nach einem Implantatbruch als möglicher Komplikation beschriebener Operation.

The research presents a case of a horse with a fractured mandible treated with a specific type of external fixator. The study details the development of a specialized tool to remove the fragments of the fixator that broke during removal, after the fracture had healed.
Treatment of the Mandibular Fracture
- The research begins with a case of a unilateral mandibular (jaw) fracture in a horse. The researchers utilized a type I external fixator, a device often used in orthopedic surgery to stabilize bone and soft tissues, to treat the fracture.
- The surgical procedure was performed while the horse was standing. At the time of the planned removal of the implant, complete healing of the fracture was confirmed.
Complications during Implant Removal
- During the removal of the outer fixator, there was a failure in two of the four implants.
- Broken bits of the implants remained embedded deep in the horse’s bone, creating a new set of complications to be addressed.
Development of a Surgical Tool and Method for Removing Implant Fragments
- The report then pivots to the creation of a specialized surgical instrument. This tool was specifically designed for the purpose of removing the remaining fragments of the broken implants.
- An ensuing surgical procedure that allowed for the complete removal of these debris during a second surgery was also described. This involved developing a new surgical technique for carrying out this type of operation.
Novelty of the Technique and Further Implications
- The authors highlight that, to their knowledge, they are the first to report on the use of this surgical technique to treat a standing horse with a broken jaw.
- The study also presents a solution on how to handle potential complications, such as implant breakage during the removal process, which could leave fragments deep within the bone. This makes the research valuable as it details an approach to tackle this particular surgical challenge.
