Objectives: To describe the use of a three-dimensional-printed patient-specific guide system for the treatment of distal tibial varus deformity in Dachshunds and retrospectively report the clinical and radiographic outcome.
Materials And Methods: Pes varus deformity in nine limbs of seven dachshunds was treated with corrective osteotomy using a three-dimensional-printed patient-specific guide system. Data from computed tomography were processed to obtain virtual 3D-models of the tibias, which were used for computer-aided design-based surgical planning, three-dimensional-printed patient-specific guide system design and evaluation of planned versus achieved tibial correction.
Objective: To describe the clinical outcomes for pugs and French bulldogs with congenital vertebral malformations, undergoing thoracolumbar spinal stabilization surgery using 3D-printed patient-specific drill guides. To evaluate the accuracy of pedicle screw placement in this group of dogs.
Study Design: Retrospective descriptive study.
Objectives: This study aimed to objectively define whether human hexapod fixation (Maxframe), with or without the use of 3D-printed positioning guides, can correct a canine antebrachial deformity with greater accuracy than the clinically established techniques of 3D patient-specific osteotomy and reduction guides (3D-PSORG) or hinged circular external skeletal fixation (CESF).
Methods: CT of a canine antebrachium was manipulated to induce distal radial deformity of the valgus, external torsion, and procurvatum, each of magnitude 20. Five experiments were performed to correct the deformity via a distal radial and ulna opening osteotomy using: (1) A 3D-PSORG with the application of a locking plate, (2) hinged CESF, (3) Maxframe standard protocol, (4) Maxframe applied with patient-specific positioning guides (PSPGs), and (5) Maxframe with frame adjustment calculated from post-application CT.
Objective: To compare the accuracy of three-dimensional (3D) printed patient-specific guide (PSG) with a freehand (FH) approach for radial osteotomies in ex vivo normal dogs.
Study Design: Experimental study.
Animals: Twenty four ex vivo thoracic limb pairs from normal beagle dogs.
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.
