Frequently Asked Questions (FAQ)
Practical answers for veterinary professionals evaluating, ordering and using OsteoCertus systems. Product selection and surgical decisions remain the responsibility of the treating veterinary professional and should follow the current product instructions and surgical technique.
Choosing products and confirming compatibility
How do I choose the correct plate for a patient?
Selection depends on the procedure and the individual patient:
- Fracture repair: choose the plate type according to patient weight and the fracture type and geometry.
- TPLO: select the implant according to the planned saw-blade cutting radius and patient weight.
- TTA: select the wedge according to the advancement required and the size of the tibia.
Review the current product page and surgical technique before ordering. If two options appear suitable, contact OsteoCertus technical support with the product family, patient weight and planned procedure for product information; final clinical selection remains with the treating veterinarian.
Where can I find dimensions and patient-weight guidance?
Use the current product tables and OsteoCertus Catalog for dimensions. These visual Technical Tips show recommended patient-weight guidance; weight is only one part of clinical selection.
Confirm the current product-specific chart before ordering; older printed revisions can differ.
Are patient-weight limits the only factor in implant selection?
No. Weight guidance is one input. Procedure, anatomy, bone quality, fracture or osteotomy geometry, activity level and construct planning also matter. The veterinarian must determine the appropriate implant and technique for the individual patient.
Which screws, drill bits and guides are compatible with a plate?
Within each system, all screw diameters fit all plate sizes. OsTi-Lok 2.4, 2.7 and 3.5 mm screws (series 101) fit OsTi-Lok fracture and TPLO plates, including series 100–104. MINI 1.5 and 2.0 mm screws (series 050) fit all MINI fracture plates. This does not make OsTi-Lok and MINI instruments interchangeable. TTA combinations must be checked against each plate’s instructions.
Screw–drill reference: LS locking and CS compression screws of a diameter share the listed pilot-drill size.
| System | Screw family | Screw Ø | Drill Ø | AO drill code | Screw color |
|---|---|---|---|---|---|
| MINI | LS15 / CS15 | 1.5 mm | 1.2 mm | AODB15-050 | White |
| MINI | LS20 / CS20 | 2.0 mm | 1.5 mm | AODB20-050 | Blue |
| OsTi-Lok | LS24 / CS24 | 2.4 mm | 2.0 mm | AODB2427-100 | Green |
| OsTi-Lok | LS27 / CS27 | 2.7 mm | 2.0 mm | AODB2427-100 | Yellow |
| OsTi-Lok | LS35 / CS35 | 3.5 mm | 2.7 mm | AODB35-100 | Purple |
Color helps identify the screw family; confirm the complete screw SKU, compatible drill code and current labeling before use. The colors above refer to screws, not drill-bit markings. See the catalog screw/instrument pages.
Can an OsTi-Lok implant be removed or revised?
It depends on the implant and the clinical situation. OsTi-Lok plates and screws may be removed or revised by the treating veterinary professional when clinically indicated. TTA wedges are 3D-printed porous implants designed for bone ingrowth; because bone can grow through their porous structure, they are not intended for routine removal and removal can be difficult. Any removal or revision requires case-by-case clinical planning, the current surgical technique, and compatible instruments.
What materials are OsTi-Lok plates and screws made from?
OsTi-Lok plates and screws are manufactured from Ti-6Al-4V titanium alloy and receive Type II anodization.
What do the product codes mean?
Our codes are intelligent: the complete SKU identifies product type, size, configuration, generation and sometimes side. Examples:
| Element | Meaning | Example |
|---|---|---|
| OL / Series 100 | OsTi-Lok (OL) family: Series 100 encompasses 100–104. Check the complete SKU in the catalog for the specific plate or instrument. | DGL-100 / PS16Q-104 |
| Q / -104 | New OsTi-Lok (OL) quadruple-lead plate generation: Q identifies a quadruple-lead plate and -104 identifies the Series 104 code. | PS16Q-104 |
| X / -050 | MINI family in many plates and instruments | PX20HS-050 / CPX20-050 |
| LS / CS | Locking / compression screw | LS15-050-06 / CS35-101-10 |
| 15 / 20 / 24 / 27 / 35 | Screw Ø 1.5 / 2.0 / 2.4 / 2.7 / 3.5 mm | LS27-101-18 = 2.7 × 18 mm |
| S / M / L | Small / medium / large OsTi-Lok size classes, corresponding to 2.4 / 2.7 / 3.5 mm screw families | PSHSQ / PMHSQ / PLHSQ |
| P / CP | Plate / Cross Plate | PSHSQ-104 / CPSQ-104 |
| HS / SB | High Strength / Short Bridge | PX20HS-050 / PX20SB-050 |
| TO + L / R | TPLO plate; left / right where applicable | TO15SQ-104L / TO15SQ-104R |
| AODB | AO-connection drill bit | AODB20-050 |
| QG / DG / SG | Quick Guide / drill guide / screw gauge | QG35-104 / DGL-100 / SGM-050 |
| W…-TTA / SBR | TTA wedge dimensions / TPLO saw-blade radius | W3x5-TTA / SBR15 |
Important: S/M/L are not literal plate thicknesses. Thickness varies by model; use its dimension table. Read the complete title, packaging and catalog code list before ordering or use.
Can OsteoCertus help build or customize a set?
Yes—from scratch if needed. We can help choose plates, screws, drill bits, guides, instruments and cases for your expected procedures. You may build your own set because components are sold individually. Preassembled instrument-and-case options are available in OsTi-Lok sets and MINI sets. Send your procedures, product codes and quantities to sa***@*********us.com for a current itemized quote.
Quick Guides and instruments
What are Quick Guides?
Quick Guides are low-profile guides for selected OsTi-Lok plate holes with angled screw trajectories. They are sold separately; only OsTi-Lok TPLO plates are also offered with guides preinstalled by hand in the angled screw holes. Match the guide, plate, screw and drill codes before use.

Which plate holes use Quick Guides?
Quick Guides are used in designated angled screw holes. On OsTi-Lok TPLO plates, they can be ordered preinstalled in those holes. They are not preinstalled on other plate families. For a separately purchased guide, match its code to the specified hole and follow the current product instructions.
Are Quick Guides reusable?
Yes. Quick Guides are reusable after appropriate cleaning, inspection and sterilization. OsteoCertus implants and instruments, including Quick Guides, are supplied non-sterile and must be sterilized before use according to the applicable product instructions and your practice’s validated process. Inspect a reused guide and do not use it if damaged or if it does not seat correctly.
How are Quick Guides removed?
Preinstalled Quick Guides are placed by hand. They can be removed by hand or, when needed, with the OsTi-Lok T10 screwdriver. Follow the current instructions for the specific plate and guide; confirm the guide is fully removed before finalizing the construct.
Ordering, availability and quotes
How can I tell whether a product is in stock?
The product page shows current online availability. If a required size is unavailable or your order is time-sensitive, contact the sales team before scheduling around the order. Availability can change until checkout is completed.
Can I request an itemized quote?
Yes. Send codes, quantities, practice name, shipping destination and any desired set configuration to sa***@*********us.com. We can prepare an itemized quote and identify compatible missing components.
Which payment methods are accepted?
Online checkout accepts major credit/debit cards and PayPal where available for the order. We also accept purchase orders subject to OsteoCertus approval after the order is placed, and bank transfers by arrangement (less commonly used). Methods shown at checkout can depend on account and destination. Questions? Email sa***@*********us.com.
Can my practice order using a purchase order?
Yes, a purchase order can be submitted with an order, but acceptance is subject to OsteoCertus review and approval afterward. Submitting a PO does not establish credit terms or confirm approval. For timing or billing requirements, contact sa***@*********us.com before ordering.
Can I save products to buy later?
Registered customers can use the Saved for Later area to organize products they may purchase in the future and move selected products back to the cart when ready. Saving a product does not reserve inventory or lock its price.
Training and support
Is training available when my practice purchases a set?
For a new customer purchasing a set, we like to arrange a complimentary introductory video call. It offers basic orientation in set use and helps our teams meet. Scheduling and scope are coordinated after purchase; orientation does not replace the current instructions or professional clinical training. Ask sa***@*********us.com when ordering.
Can training be customized for our team?
Yes. Personalized programs led by Dr. David Silva may combine a virtual session with practical on-site training at your facility. Content, duration, travel and price are quoted individually. See the Custom Training page for details and a quote request. Training does not replace clinical qualifications or case-specific judgment.
Where can I find manuals, surgical techniques and videos?
Open each PDF to check its revision against the product in hand:
- OsteoCertus Catalog
- TPLO Surgical Technique
- TTA Surgical Technique
- TPLO Saw Manual
- Multi-Functional Drill Manual
See our Videos and Technical Tips. For a missing or uncertain revision, email co*****@*********us.com.
How can I bend or cut OsTi-Lok plates?
Watch the How to bend & cut OsTi-Lok plates videos for OsTi-Lok and MINI. Follow product-specific safe bending ranges and instructions; not every plate can be cut or contoured in the same way. Final construct planning belongs to the treating veterinarian.
Can I see clinical examples for a specific plate or procedure?
Search the Clinical Case Finder by procedure, system or case number. Examples are educational and do not determine the appropriate treatment for another patient. If you cannot find a relevant example, contact the team and describe the product family or procedure of interest.
Quality, product concerns and returns
What should I do if a screw, plate or instrument does not perform as expected?
Stop using the affected component when safe to do so and contact OsteoCertus promptly. Keep the product and packaging, and provide the product code, lot number, clear photos and a factual description of what occurred. Do not modify or discard the item unless instructed. Urgent patient-care decisions belong to the treating veterinary team.
What information helps the quality team investigate a concern?
Include your contact information, product and lot codes, order reference, date of use, compatible instruments used, photos or imaging when appropriate, and a concise sequence of events. Remove patient-identifying information unless it is specifically required through an approved secure channel.
Will a product be replaced or credited?
The published Quality Guarantee provides replacement or credit, at no cost, for products that fail to perform as intended under normal use within its use limits. Implants and instruments other than drilling/cutting tools have no time limit; drilling/cutting tools are covered for one month from purchase, power tools for one year and batteries for six months. OsteoCertus may request the failed item for investigation. See the Return Policy and contact co*****@*********us.com before returning anything.
