The Case

Loki, a 1.5-year-old German Pinscher weighing 16 kg, was referred to Tierklinik Altheim GmbH in Austria following a series of intermittent epileptiform seizures. These episodes began after an accident on 15 July 2025, causing significant concern for his owners and leading to a comprehensive neurological investigation.

Diagnosis

Advanced imaging via CBCT revealed a complex structural issue: an open fontanelle paired with an exostosis. This bony protrusion was pressing directly into the cranial cavity. It became clear that surgical intervention was necessary to remove the pressure on the brain and stabilize the skull to prevent further neurological decline.

The Procedure

The surgery was performed by Dr. Simon Hebenstreit and Dr. Walter Hebenstreit. The procedure involved opening the skull to carefully remove the protruding exostosis.

To complete the reconstruction, the surgical team had to close both the resulting surgical defect and the pre-existing open fontanelle. For this, they utilized LeiMESH by Rita Leibinger Medical. The LeiMESH system was selected for its ability to provide stable, permanent coverage while adapting perfectly to the patient's cranial anatomy.

Recovery and Results

Loki’s recovery has been remarkable. Since the surgery, his general behavior has returned to that of a healthy and energetic young dog. While he has had two minor, brief episodes, his owners describe him as a "completely different dog." The chronic symptoms that previously shadowed his life have vanished, and his quality of life has been fully restored.

Clinical Takeaway

Loki’s success highlights the importance of precise implant selection in veterinary neurosurgery. By combining surgical expertise with the flexibility of LeiMESH, the surgical team was able to resolve a complex skull defect and provide a long-term solution for a patient with a challenging neurological prognosis.

About the

LeiMESH 3D Dynamic System

THREE DIMENSIONAL ADAPTIBILITY

Each LeiCAGE implant is 3D-printed from medical-grade titanium, featuring a porous lattice structure (dodecahedron construction) that encourages rapid bone ingrowth and long-term osseointegration. This design replicates cancellous bone architecture, facilitating direct biological fusion between vertebral bodies and promoting stable load transfer during the healing process.

TITANIUM FOR BEST BIOCOMPATIBILITY

Made of medical-grade Titanium, LeiMESH is highly biocompatible, strong yet lightweight, corrosion-resistant, and promotes bone integration. Its flexibility makes it suitable for custom shaping and its non-magnetic properties makes it safe for MRI scans.

PERFECT BALANCE OF STRENGTH AND FLEXIBILITY

The thickness of LeiMESH provides sufficient structural support while allowing flexibility to customize the mesh to fit complex contours.

Compact, Tissue-Sparing Profile

The compact design of the screw head and rod construct facilitates implantation in tight anatomical corridors, reduces implant prominence and protects surrounding musculature and vascular structures from irritation or damage.

VARIOUS APPLICATIONS

LeiMESH is highly versatile and can be used in various medical applications such as cranial fractur repair, bone fracture management, bone cement augmentation, and maxillofacial reconstruction surgeries.

LOW PROFILE CROSS DRIVE TITANIUM SCREWS

Made of Titanium to ensure seamless biocompatibility. LeiMESH Screws feature a low-profile head for minimal tissue irritation. Compatible with the LeiMESH Screwdriver, the LeiMESH Cross Drive screws provide a secure fixation, fitting perfectly into the screw holes of the Titanium Mesh to meet diverse anatomical and surgical requirements. Additionally, they offer a self-holding. capability similar to LeiStar screws.
