Article Synopsis
- The study aimed to evaluate the effectiveness and precision of using 3D-printed guides versus freehand methods for placing Kirschner wires in the femurs of dogs, focusing on novice versus experienced surgeons.!
- It involved creating 3D models of dog femurs, followed by virtual surgical planning, and then comparing the results of wire placements with freehand techniques and those guided by 3D-printed models.!
- Results indicated that 3D-printed guides led to quicker procedures, fewer complications, and better accuracy in wire placement, highlighting the need for further research in practical applications for surgeries in dogs.!
Objective: To compare the effect of a geometric, landmark-guided lymphadenectomy (LL) approach to peripheral lymph nodes (LNs) on successful LN identification, surgical time, tissue trauma, and ease of LN identification compared to standard lymphadenectomy (SL) and methylene blue-guided lymphadenectomy (MBL).
Sample: 18 adult, mixed-breed canine cadavers operated on by 7 veterinarians and 5 fourth-year veterinary students between July 23 and October 12, 2022.
Methods: Participants were provided standardized, publicly available materials regarding the anatomy and surgical techniques for SL of 3 peripheral lymphocentrums: superficial cervical, axillary (ALN), and superficial inguinal (SILN).
Article Synopsis
- - The study aims to evaluate how six different proximal tibial osteotomies affect the geometry and alignment of canine tibias with varying degrees of tibial plateau angle (TPA).
- - Thirty canine tibias were examined, categorized into three groups based on TPA, and simulated surgeries were assessed using orthopedic planning software to measure shifts in tibial structure after correction.
- - Results showed that the TPLO/CCWO procedure led to minimal changes in tibial structure, while the coCBLO technique caused the most significant alterations; the mCCWO option effectively balanced geometry changes with osteotomy overlap preservation.
Objective: To utilize the geometry of superficial anatomic landmarks to guide incisional location and orientation for peripheral lymphadenectomy, document deep anatomic landmarks for lymphocentrum identification, and develop novel surgical approaches to the superficial cervical, axillary, and superficial inguinal lymphocentrums in dogs.
Animals: 12 canine cadavers.
Procedures: 2 cadavers were used for a pilot investigation to determine optimal body positioning, select superficial anatomic landmarks for lymphocentrum identification, and evaluate novel surgical approaches to the 3 lymphocentrums.
Objective: The aim of this study was to evaluate the effect of stem positioning on the biomechanical performance of a novel, collared, short-stem total hip implant under compression and torsion .
Study Design: Six canine cadaveric femurs were implanted with a collared short-stem femoral implant. Canal flare index (CFI), stem angle, absolute and relative cut heights and relative size were measured radiographically and used as independent variables.
Objective: The aim of this study was to evaluate the relationship between radiographic fit/fill measurements and biomechanical performance of three canine cementless total hip implant designs using an biomechanical testing protocol that replicates compression and torsion.
Study Design: Eighteen (six/group) canine cadaveric femurs were implanted with one of three cementless total hip implant designs: (1) collarless, (2) collared or (3) lateral bolt stems. Femoral length, canal flare index (CFI), canal fill, stem fit, stem level and stem angle were measured as independent variables.
