Three-dimensional printed surgical guides for keratoma removal in horses using computed tomography or magnetic resonance imaging-based segmentation.

Objective: To report the technique, surgical approach, and postoperative features in horses treated via a 3-dimensional (3D) printed guide-assisted keratoma resection created using computed tomography (CT) or magnetic resonance imaging (MRI)-based segmentation.

Animals: Five client-owned horses.

Study Design: Short case series.

Three-dimensional printed guides for screw placement in equine navicular bones.

Objective: To determine the influence of a custom 3D-printed guide for placement of cortical bone screws in the equine navicular bone.

Study Design: Ex vivo study.

Sample Population: Eight pairs of normal adult equine forelimbs.

Use of Hausdorff Distance and Computer Modelling to Evaluate Virtual Surgical Plans with Three-Dimensional Printed Guides against Freehand Techniques for Navicular Bone Repair in Equine Orthopaedics.

Objective:  The aim of this study was to evaluate the surgical execution of a virtual surgical plan (VSP) with three-dimensional (3D) guides against a freehand approach in the equine navicular bone using an automated computer analysis technique.

Study Design:  Eight pairs of cadaveric forelimb specimens of adult horses were used in an experimental study design with modelling. Limbs received either a 3.

Endoscopic Laser Ablation of a Midline Cyst of the Colliculus Seminalis as a Treatment for Anejaculation in a Stallion.

An 18-year-old Appaloosa stallion presented with a history of ejaculatory dysfunction, which had recently progressed to an inability to ejaculate (anejaculation). Transrectal ultrasound evaluation revealed the presence of a prominent midline cyst of the colliculus seminalis, which was compressing the most terminal parts of the deferent ducts. Both ducts were enlarged and filled with hyperechoic content.
