OOOPDS — Surgical Planning Software
Do the operation once on screen. Then do it once for real.
OOOPDS turns a patient's own CT or MRI data into an accurately scaled 3D model, then lets the surgeon work on it before the case: reduce the fracture, plan the screw path, shape the plate, print it. What arrives in theatre is a decision that has already been made and checked.

What it is
Taiwan's first fully domestic orthopaedic planning software
OOOPDS is the first and only 100 % domestically developed orthopaedic surgical planning software in Taiwan, licensed by the Ministry of Health and Welfare (TFDA). It brings 2D and 3D medical imaging, surgical simulation and 3D printing together in one system, so patient-specific planning happens in a single place instead of across three.
From DICOM data to a model you can operate on
OOOPDS loads and processes 2D images in DICOM format — the global standard for medical imaging — and reconstructs them into a 3D model held at the patient's real scale, overlaid and aligned with the anatomy it came from. Nothing is approximated from a textbook: the model is that patient's bone.
Finished objects export as .stl, .ply or .obj, which is what makes the step from planning to a printed model or template a file transfer rather than a project.
- Multi-directional 2D cross-sections along the X, Y and Z axes, read alongside the 3D view
- Interactive 3D models that can be rotated, cut and separated for precise anatomical visualisation
- Planning, simulation and printing in one workflow, from DICOM import through to the file that goes to the printer
Preoperative planning
Analyse the injury and simulate the operation, so the surgeon reaches the table already familiar with the case rather than meeting it for the first time.
3D printing integration
Modelling and printing give a tangible spatial reference for where the bone fragments actually sit — something no screen fully replaces.
Customised bone plate design
Everyone's skeleton is different. Patient data goes in and a plate designed to that anatomy comes out, so less of it has to be bent in theatre.
One system, three fields
Orthopaedic, spinal and dental planning run on the same software, the same imported data and the same set of tools.
Preoperative planning
Personalised planning for every patient
Better decisions in theatre start before anyone scrubs. OOOPDS turns raw imaging into a plan the team can look at together — accurate, specific to the patient in front of them, and settled while there is still time to change it.
Five tools that do most of the work
From trauma to spine and dental cases, the planning suite covers the sequence a surgeon actually follows: understand the anatomy, put the pieces back, choose the hardware, and check that the path to it is safe.
- 2D/3D visualisation — switch between cross-sections on the X, Y and Z axes and a fully interactive reconstruction
- Fracture simulation — move fragments by hand, or apply auto-symmetry against the healthy side, to find the alignment
- Implant simulation — choose screws and plates and place them, adjusting angle, depth and position as you go
- Customised plate design — design the plate on the reduced fracture and export it straight for printing
- Puncture and screw trajectory planning — axial, sagittal and coronal views with the 3D overlay, to keep the path clear
Increased surgical accuracy
The approach is chosen against the patient's real anatomy rather than inferred from flat images during the case.
Reduced operating time
Implant position and fragment reduction are settled in advance, and the minutes saved are the expensive ones.
Improved patient outcomes
Less guesswork tends to mean better alignment, and better alignment is what the healing depends on.
Team collaboration
Planning results can be exported and discussed by the whole surgical team, and shown to the patient, before the day of the operation.
Inside the software
What the simulation actually looks like
Each clip below is recorded from OOOPDS itself, working on real imported patient data. No step is a mock-up of the interface — this is the software a surgeon sits in front of the evening before the case.
Manual fracture reduction
An accident rarely produces one clean break. Fragments are separated and moved by hand in 3D, so the reduced position is planned in advance instead of being worked out with the patient open.
SI screw locking
The same simulation applies to the pelvis. Against the 3D X-ray image the surgeon finds a workable locking path across the sacroiliac joint and confirms the screw's diameter and length before ordering it.
Spinal puncture path
Proportional 3D images read together with X-ray and 2D cross-sections, so the entry point, angle, length and depth can be planned around the neurovascular structures rather than into them.
Spine pedicle screw simulation
The patient's DICOM data is imported and the pedicle screws analysed in place: diameter and length are confirmed on the model, and the connecting rods are generated automatically once the screws are set.
Implant screw planning
For dental work, imported DICOM data of the affected area is converted to 3D, the dental arch curve is set, and the chosen implant is locked in with its spatial position adjusted in simulation.
Segmentation and auto-reduction
Automatic bone segmentation, cutting and 3D object modelling, plus manual and automatic symmetric reduction — which mirrors the intact side to show where the broken one should end up.
System tools
The tools around the simulation
Image adjustment switches between skin and bone tissue, converts 2D brightness and tunes the 3D reconstruction threshold. Area separation splits, merges, hides and rebuilds each region of bone fragments. Meshing turns integrated regions into surface triangular meshes for export. The brush annotates directly on the image, which turns the same window into a teaching surface. Measurement covers length, angle, the angle between two segments, area, and volume and bone density on the 3D view.
3D printing
Turning data into something you can hold
A screen shows a surgeon the anatomy. A printed model lets them turn it over in their hands. OOOPDS supports the whole path — import the DICOM data, build and adjust the model, export it, print it — so the object that reaches the table came from this patient's scan and nothing else.
Three steps, one file
3D printing builds a physical object from a digital model by adding material layer upon layer. In medicine that means patient-specific bones, organs, implants and surgical guides — and in OOOPDS the digital model is the same one the surgeon has just planned on.
- Data upload and 3D modelling — DICOM data from CT, MRI or X-ray becomes a model of that patient's structure
- Customisation and design — bone plates, surgical guides and implant designs are shaped to fit before anything is made
- Printing — the model is printed in biocompatible material and used in theatre as a reference or a guide
The model goes into theatre with the team
The photograph alongside is a real case. The scrubbed surgeon is holding a printed pelvis taken from that patient's own scan and shaping the fixation plate against it, on the sterile field, seconds before it goes in. Bending a plate against the actual shape of the bone is not a rehearsal — it is the operation, done a step earlier and under no time pressure.
The same model answers the question a scan cannot: how the fragments sit relative to one another when you look at them from the side the incision will come from.
Enhanced surgical precision
Surgeons plan against a structure they can see and handle from every side, rather than assembling it mentally from slices.
Faster decisions
With a model in hand an approach can be tested and changed in minutes, which is worth most in exactly the complex cases that take longest.
Patient-specific hardware
Implants, plates and guides are made to one anatomy, so far less has to be adjusted while the patient is open.
Planning and training
The same printed models make a complex procedure easier to rehearse, and are a teaching tool for the people who will do it next.
Beyond orthopaedics
The same workflow, other specialties
Bone is where OOOPDS started, but a DICOM data set is a DICOM data set. Cardiology uses printed hearts to plan valve replacements and rehearse catheter work; dentistry prints models for implant placement and orthodontic treatment; neurosurgery prints skulls for tumour and spinal work; and custom implants and prosthetics are designed to one person's measurements. OOOPDS can produce heart models from DICOM data in the same way it produces bone.
Customised bone plate
Precision fit, from the patient's own anatomy
Every skeleton is different, and a plate bent to a generic curve has to be re-bent against a specific one — usually in theatre, usually while the clock runs. OOOPDS designs the plate on the reduced fracture instead, then hands it to the printer.
Designed on the fracture, not on the table
Patient DICOM data is imported and converted to 3D, the fracture is reduced in simulation, and the plate's shape, size and length are drawn onto the result with its fixation points chosen for stability. What comes out is a plate, or a template to bend a plate against, that already matches the bone.
- Improved fit — far less adjustment needed during the operation
- Better alignment — a plate that follows the bone fixes it where it should heal
- Shorter operating time — the shaping happens before the case, not inside it
- Theatre efficiency — removing intraoperative adjustment takes cost out of the list as well as time
Fracture fixation
Complex fractures where a standard plate does not follow the bone closely enough to hold the reduction it is meant to hold.
Joint reconstruction
Repairs to a joint or a bone surface, where the fixation has to match a shape that carries load in a particular way.
Pelvic and spinal fixation
Alignment in the areas where the margin for error is smallest and the consequences of getting it wrong last longest.
Clinical applications
Three specialties, one planning system
The imaging chain is the same wherever the operation happens: DICOM in, a scaled 3D model out, a simulated plan on top of it. What changes is what the surgeon is planning — a fracture, a trajectory through the spine, or an implant in a jaw.
Orthopaedics
Preoperative planning for skeletal trauma: fracture patterns read on 2D and 3D reconstructions, reduction strategies simulated manually or by symmetry, screw paths and plate placement decided in advance, and custom plates exported for printing. Fracture management, trauma reconstruction, pelvic fixation and SI screw locking all run through the same workflow.
Neurosurgery
High-resolution imaging turned into detailed 3D models of complex structures, then used to plan pedicle screw placement and spinal puncture paths on that patient's anatomy. Rehearsing the procedure before the room is booked is what takes risk out of it — and shorter, better-prepared operations are safer ones.
Dentistry
CBCT data reconstructed in 3D for tooth position, impacted third molars and jawbone assessment, then virtual implant placement with angulation, depth and proximity to critical structures checked before surgery. Planning from the intended prosthetic result backwards keeps function and appearance in the same decision.
Peer-reviewed
What it saved, measured on real cases
A study of 21 patients with traumatic anterior pelvic ring fractures, published in the Journal of Orthopaedic Surgery and Research, compared two ways of preparing the fixation plate: contouring it on a full 3D-printed pelvic model, or contouring it on a plate template designed in OOOPDS and printed on its own.
Printing fell from 926.9 ± 202.95 minutes to 58.29 ± 33.45, and pre-contouring the plate from 62.50 ± 21.45 minutes to 6.24 ± 2.39 — both differences significant at P < 0.01. Roughly a full working day of preparation became roughly an hour.
An independent academic publication, linked in full so the method and its limitations can be read alongside the numbers. It is a single-centre study of 21 patients.
