Biological interaction of bioactive polymeric membranes in induced bone defects in rabbit tibias.

The study aimed to evaluate bone repair using three osteoinductive polymers in bone defects created in rabbit tibias. Forty-eight adult rabbits were assessed at various time points: three, seven, fourteen, and thirty days. The groups included a control group (without biomaterial), M1 (Poly L Lactide co Polycaprolactone/Polyethylene Glycol), M2 (Poly L Lactide co Polycaprolactone/Polyethylene Glycol/β-Tricalcium Phosphate), and M3 (Poly L Lactide co Polycaprolactone/Polyethylene Glycol/nano hydroxyapatite).

Comparison of the deformity reduction device (DRD) mini and the Slocum jig in the precision of torsional correction during distal femoral osteotomies in small to medium breed dogs.

Previous studies have compared the use of the Slocum- jig to the deformity reduction device (DRD) jig for the correction of distal femoral deformities of varying degrees in the frontal plane. The objective of the current study is to further investigate the use of the mini DRD jig in comparison to the Slocum jig for correction of varying degrees of torsional deformities of the distal femur. Femoral models (n = 60) were developed based on a CT scan of an approximately 16.

Locking conical coupling plates in small animal orthopedics: A review.

Conical coupling locking plates (CCP) have become an interesting alternative in veterinary orthopedics and traumatology. Available data in this regard, however, must be interpreted with caution, and several studies are still required to reach definitive conclusions on the clinical use of these implants. In this context, this review aims to discuss CCP applications and mechanical aspects in small animals and summarize in vivo, in vitro and ex vivo study results.

Comparison of Cervical Stabilization with Transpedicular Pins and Polymethylmethacrylate versus Transvertebral Body Polyaxial Screws with or without an Interbody Distractor in Dogs.

Objective:  The main aim of this study was to compare the biomechanical properties of caudal cervical vertebral stabilization using bicortical transpedicular pins with polymethylmethacrylate (PMMA) versus transvertebral body polyaxial screws and connecting rods with or without an interbody distractor.

Study Design:  Ten canine cervical vertebral columns (C2-T3) were used. Four models (intact, transvertebral body polyaxial screw with interbody distractor [polyaxial + distractor], transvertebral body polyaxial screw without interbody distractor [polyaxial - distractor] and bicortical transpedicular pins/polymethylmethacrylate [pin-PMMA]) were applied to C6-7 sequentially on the same specimens.

Calcium sulfate antibiotic-impregnated bead implantation for deep surgical site infection associated with orthopedic surgery in small animals.

Objective: To report the outcomes and complications associated with antibiotic-impregnated calcium sulfate beads for prevention and treatment of orthopedic-related surgical site infection (SSI) in companion animals.

Study Design: Retrospective case series.

Animals: Client-owned cats (n = 2) and dogs (n = 14).

Comparison of a 3-hole 4.5-mm Dynamic Compression Plate and a 7-hole 5.5-mm Y Locking Compression Plate for Arthrodesis of the Proximal Interphalangeal Joint in Horses-an Ex Vivo Biomechanical Study.

The objective of this study was to compare the biomechanical properties in a single cycle axial loading test and the types of failures in two constructs (a 3-hole 4.5-mm dynamic compression plate (DCP) and 7-hole 5.5-mm Y locking compression plate (Y-LCP)) in equine proximal interphalangeal joint (PIJ) arthrodesis.

Comparative Analysis of Vertical Forces in Dogs Affected with Cranial Cruciate Ligament Disease and Tibial Plateau Angles Greater or Less than 25 Degrees.

Objective:  Our objective was to compare the peak vertical force (PVF) and vertical impulse (VI) between dogs with cranial cruciate ligament disease and a tibial plateau angle (TPA) greater or less than 25 degrees.

Methods:  A retrospective study was performed in 18 dogs with cranial cruciate ligament disease in which kinetic gait data were obtained with a pressure walkway system. Dogs were distributed in two groups: dogs with a TPA ≤ 25 degrees ( = 8) and dogs with a TPA > 25 degrees ( = 10).

Otoscopic evaluation of epithelial remnants in the tympanic cavity after total ear canal ablation and lateral bulla osteotomy.

Objective: To determine the ability to detect the presence of epithelial remnants after total ear canal ablation (TECA) and lateral bulla osteotomy (LBO) with endoscopy and to identify the most common locations of epithelial remnants after tympanic curettage.

Study Design: Experimental study.

Animals: Five fresh canine cadavers with no gross evidence of middle ear disease.

Short-term comparison of tibial tuberosity advancement and tibial plateau levelling osteotomy in dogs with cranial cruciate ligament disease using kinetic analysis.

Objectives: This study set out to compare the outcomes of tibial tuberosity advancement (TTA) and tibial plateau levelling osteotomy (TPLO) procedures in the treatment of dogs affected with unilateral cranial cruciate ligament disease (CCLD) based on subjective parameters and objective pressure platform analysis (baropodometry).

Methods: Twenty-seven adult dogs weighing over 20 kg that were presented with unilateral CCLD and were treated by the TTA (12 dogs) or TPLO (15 dogs) surgical procedure. Patient allocation to either group was based on tibial plateau angle (TPA), according to clinical guidelines (indication for TTA for dogs was a TPA up to 25°, and indication for TPLO was any TPA).

Evaluation of the effects of methadone and tramadol on postoperative analgesia and serum interleukin-6 in dogs undergoing orthopaedic surgery.

Background: Acute postsurgical pain is of great interest due to potential risk of becoming chronic if not treated properly, worsening patient's recovery and quality of life. Twenty-eight dogs with ruptured cruciate ligaments were divided into three groups that received intramuscular injections of 4 mg/kg of tramadol (TRA), 0.5 mg/kg of methadone (MET0.

[Biomechanical analysis of the normal knee and with cranial cruciate ligament rupture to the cranial translation degree and articular stiffness in dogs].

Purpose: To analyse the biomechanical function of the knee joint in dogs, comparing the cranial translation degree and articular stiffness of the tibia in relation to the femur, in normal joints and joints with rupture of cranial crucial ligament.

Methods: Ten mongrel dog knees were analyzed, weighting more than 20 kg. Biomechanical analysis to the cranial translation degree of the knee joint with normal cranial cruciate ligament and surgically sectioned was made.
