“…An epiperiosteal tunnel could be developed between the incisions made for pin guide application to perform MIPO, and application of a properly contoured plate could be used to further improve reduction and alignment. [1][2][3][4][5]8,9,11,29,30,47 However, application of a plate and screws would have produced substantial artifacts on our postreduction CT images, which may have decreased the accuracy of our assessments. We assessed reduction and alignment via CT images and 3-D rendering.…”

M inimally invasive plate osteosynthesis (MIPO) is an emerging treatment modality in small animal orthopedics. [1][2][3][4][5] MIPO uses indirect reduction techniques to align the major fracture segments prior to implant application. Manual traction, intramedullary pins, external fixators (EFs), and appropriate plate contouring have been used to facilitate indirect closed reduction of appendicular long bone fractures during MIPO in dogs.

OBJECTIVE To assess the feasibility and accuracy of using 2 methods for reduction and alignment of simulated comminuted diaphyseal tibial fractures in conjunction with 3-D–printed patient-specific pin guides. SAMPLE Paired pelvic limbs from 8 skeletally mature dogs weighing 20 to 35 kg. METHODS CT images of both tibiae were obtained, and 3-D reconstructions of the tibiae were used to create proximal and distal patient-specific pin guides. These guides were printed and used to facilitate fracture reduction and alignment in conjunction with either a 3-D–printed reduction guide or a linear type 1A external fixator. Postreduction CT images were used to assess the accuracy of pin guide placement and the accuracy of fracture reduction and alignment. RESULTS The 3-D–printed guides were applied with acceptable ease. Guides for both groups were placed with minor but detectable deviations from the planned location (P = .01), but deviations were not significantly different between groups. Fracture reduction resulted in similar minor but detectable morphological differences from the intact tibiae (P = .01). In both groups, fracture reduction and alignment were within clinically acceptable parameters for fracture stabilization by means of minimally invasive plate osteosynthesis. CLINICAL RELEVANCE Virtual surgical planning and fabrication of patient-specific 3-D–printed pin guides have the potential to facilitate fracture reduction and alignment during use of minimally invasive plate osteosynthesis for fracture stabilization.

“…Fractures of the femur represent about half of all long bone fractures in dogs and cats (Unger et al, 1990;Gadallah et al, 2009). Fracture reduction involves the restoration of normal bone length and alignment and highlights how well a fractured bone has been reapposed (Gadallah et al, 2009;Pozzi et al, 2021). The ethic is to manage the fracture in a manner that will restore normal anatomy and maintain the reduction position through the fixation technique (Delaspenas et al, 2011).…”

Femoral diaphyseal fractures are usually amenable to reduction with the use of orthodox fixation implants, which in most cases are expensive and cause intense stress to the patient, hence the need for safer, new biomaterials. This study assessed the use of allo-cadaveric bone plates (CBP-A) and conventional bone plates in managing femoral fractures in dogs. A total of four 8-12 kg Nigerian indigenous dogs were randomly divided into two groups, with each consisting of a male and female dog. Sterilized osteotome wire was employed to surgically create transverse mid-shaft femoral fractures in all the dogs. The fractures in Group I dogs were managed using Vitallium-alloy bone plates and served as control, while Group II fractures were reduced and fixed using CBP-A. Clinical and radiographic assessments for three months were carried out to compare the fracture healing between the groups. Results showed an early stabilization of vital parameters with a premature attempt to use the operated limb on days 4 and 5 post-reduction in groups I and II, respectively. The radiographs revealed good fracture reduction and fixation in all the dogs with the gradual disappearance of the fracture line, as well as progressive bone remodelling as the fracture healing advanced through the sixth week. At 12 weeks, there was distinct medullary and cortical continuity in all the dogs. Therefore, the novel CBP-A used in this study has effectively provided the needed fixation stability with minimal external immobilization for the repair of dog femoral fractures; hence, it should be recommended for use.

“…5 Closed indirect reduction of femoral fractures is especially problematic due to the abundant surrounding musculature. 6,7 Several indirect fracture reduction techniques have been described to facilitate MIPO applications. 5,[8][9][10] In a retrospective case series, 10% of femoral fractures stabilized via MIPO performed without intraoperative imagining required immediate surgical revision.…”

ObjectiveAssess the accuracy and efficiency of reduction provided by application of plates precontoured to 3‐dimensional (3D)‐printed femoral bone models using a custom fracture reduction system (FRS) or intramedullary pin (IMP) to facilitate femoral minimally invasive plate osteosynthesis (MIPO) in dogs.Study designExperimental cadaveric study.Sample populationSeven dog cadavers.MethodsVirtual 3D femoral models were created using computed tomographic images. Simulated, virtual mid‐diaphyseal femoral fractures were created and reduced. Reduced femoral models were 3D‐printed and a plate was contoured. Custom drill guides for plate screw placement were designed and 3D‐printed for the FRS. Mid‐diaphyseal simulated comminuted fractures were created in cadavers, and fractures were aligned using FRS or IMP and stabilized with the precontoured plates. Number of fluoroscopic images acquired per procedure and surgical duration were recorded. Computed tomographic scans were repeated to assess femoral length and alignment.ResultsCompared to the preoperative virtual plan, median change in femoral length and frontal, sagittal, and axial alignment was less than 3 mm, 2°, 3°, and 3° postoperatively, respectively, in both reduction groups. There was no difference in length or alignment between reduction groups (P > .05). During FRS, fewer fluoroscopic images were taken (P = .001), however, surgical duration was longer than IMP procedures (P = .011).ConclusionFemoral alignment was accurate when using plates precontoured to 3D printed models, regardless of reduction method.Clinical significanceAccurate plate contouring using anatomically accurate models may improve fracture reduction accuracy during MIPO applications. Custom surgical guides may reduce fluoroscopy use associated with MIPO.
