Surgical enlargement of the nasomaxillary aperture and transnasal conchotomy of the ventral conchal sinus: Two surgical techniques to improve sinus drainage in horses.

Objective: To evaluate 2 surgical techniques for establishing and/or improving paranasal sinus drainage in cadaver heads and horses with sinusitis and evaluate the feasibility of postoperative transnasal sinus endoscopy.

Study Design: Ex vivo study (equine cadaver heads) and case series.

Sample Population: Nine adult equine cadaver heads and 8 horses with recurrent sinusitis.

Bacterial meningitis after sinus surgery in five adult horses.

Objective: To report meningoencephalitis as a complication after paranasal sinus surgery in 5 horses.

Study Design: Case series.

Animals: Adult horses (n = 5).

Virtual monochromatic spectral imaging with fast kilovoltage switching: reduction of metal artifacts at CT.

With arthroplasty being increasingly used to relieve joint pain, imaging of patients with metal implants can represent a significant part of the clinical work load in the radiologist's daily practice. Computed tomography (CT) plays an important role in the postoperative evaluation of patients who are suspected of having metal prosthesis-related problems such as aseptic loosening, bone resorption or osteolysis, infection, dislocation, metal hardware failure, or periprosthetic bone fracture. Despite advances in detector technology and computer software, artifacts from metal implants can seriously degrade the quality of CT images, sometimes to the point of making them diagnostically unusable.

Direct arthrography of the pisotriquetral joint.

Objective: The purpose of this study was to describe and evaluate a simple and safe procedure for direct arthrography of and steroid injection into the pisotriquetral joint.

Conclusion: Direct pisotriquetral arthrography using a medial approach is an effective and easy-to-perform technique for injection of steroids.

Anterior cruciate ligament reconstruction with bioabsorbable polyglycolic acid interference screws: MR imaging follow-up.

Purpose: To examine at magnetic resonance (MR) imaging the degradation of an interference screw made of polyglycolic acid (67.5%) and trimethylene carbonate (32.5%) and compare the MR findings with the clinical evaluation results.
