3D-Printed Osteoinductive Polymeric Scaffolds with Optimized Architecture to Repair a Sheep Metatarsal Critical-Size Bone Defect.

The reconstruction of critical-size bone defects in long bones remains a challenge for clinicians. A new osteoinductive medical device is developed here for long bone repair by combining a 3D-printed architectured cylindrical scaffold made of clinical-grade polylactic acid (PLA) with a polyelectrolyte film coating delivering the osteogenic bone morphogenetic protein 2 (BMP-2). This film-coated scaffold is used to repair a sheep metatarsal 25-mm long critical-size bone defect.

Preoperative computed tomography, surgical treatment and long-term outcomes of dogs with abscesses on migrating vegetal foreign bodies and oropharyngeal stick injuries: 39 cases (2010-2021).

Objectives: This study evaluated success rates of surgical treatment of head and neck abscesses and draining tracts for suspected migrating vegetal foreign body and oropharyngeal penetrating injuries, and compared the outcomes according to whether a vegetal foreign body was identified in preoperative computed tomography (CT) examination.

Materials And Methods: This retrospective study involved 39 dogs that underwent CT and subsequent surgical exploration of abscesses and/or draining tracts in the head and neck, in a single institution between 2010 and 2021. Recorded data included signalment, history, physical examination, CT and surgical findings.

Needle arthroscopy for exploration of the elbow joint: a case series of six dogs with preliminary cadaveric study.

Case History: Dogs (n = 6) suffering from elbow-associated lameness for a median of 3.5 (min 2, max 12) months duration requiring arthroscopic exploration according to imaging results were prospectively included in this study.

Clinical Findings: Dogs that met the inclusion criteria were of various breeds with a median body weight of 18 (min 13.

Outcomes of 25 female dogs treated for ectopic ureters by open surgery or cystoscopic-guided laser ablation.

Objective: To report outcomes after the correction of ectopic ureter (EU) by open surgery or cystoscopic-guided laser ablation (CLA) in female dogs.

Study Design: Retrospective study from 2011 to 2018.

Animals: Twenty-five female dogs.

Surgical treatment of a distal oesophageal stricture by mucosal radial incision and dilation in a kitten with secondary megaoesophagus.

Case Summary: A 7-month-old intact female Maine Coon cat was presented with a 2-month history of regurgitations. Contrast radiographic and endoscopic examinations revealed a diffuse megaoesophagus secondary to a severe lower oesophageal stricture. An epiphrenic diverticulum was noted.
