Chairside Orthotic Adaptions
Chairside Orthotic Adaptation Guide
Real-Time Customisation for Optimal Comfort and Function
Chairside orthotic adaptation refers to the process of adjusting and modifying orthotic devices directly within the clinic or podiatry practice, typically during a patient’s appointment. This real-time, hands-on approach allows healthcare professionals to fine-tune orthotics on the spot, ensuring a more accurate fit, better comfort, and improved biomechanical performance for each individual. In Australian podiatry and orthotic practice, this technique is widely adopted for semi-bespoke and prefabricated orthotic devices such as Slimflex Orthotics, due to their affordability, adaptability and easy modification.
What Is Chairside Orthotic Adaptation?
Chairside adaptation is the process of modifying an orthotic device while the patient is present. This may include grinding, heat-moulding, cutting, or adding padding to refine the shape, contour or functional elements of the orthotic. By making adjustments immediately, practitioners can respond directly to the patient’s feedback and achieve an optimised result in a single session. This approach saves time, enhances comfort, and increases patient satisfaction compared to sending devices back for lab modification.
The Chairside Adaptation Process
1. Patient Evaluation
The process begins with a detailed assessment of the patient’s feet, gait, and overall biomechanics. The practitioner observes how the patient interacts with their orthotic device — identifying areas of excessive pressure, instability or discomfort. This initial evaluation sets the foundation for targeted and effective modifications.
2. Identifying Issues
Common issues identified during assessment may include rubbing, irritation, arch misalignment, or uneven pressure distribution. These can occur due to subtle anatomical differences, gait abnormalities or wear patterns in the orthotic. Recognising these concerns early allows for precise, problem-specific intervention.
3. Modification Techniques
Chairside adaptation involves a range of modification techniques and materials designed to improve fit, function and comfort. Typical methods include:
- Grinding: Removing small amounts of material to improve contour, relieve pressure points or adjust posting angles.
- Heat Moulding: Applying gentle heat to reshape thermoplastic or EVA orthotics for better foot conformity.
- Cutting or Trimming: Adjusting edges or shortening the orthotic to fit different footwear types.
- Padding and Additions: Bonding pads, cushions, or wedges to modify support, redistribute load and enhance comfort.
4. Real-Time Feedback
One of the greatest advantages of chairside modification is immediate patient feedback. Patients can test the orthotic as adjustments are made, describing changes in comfort, stability and alignment. This dynamic interaction enables practitioners to fine-tune adjustments until the ideal result is achieved, avoiding guesswork and multiple return visits.
5. Patient Education
During the process, the clinician explains each modification and educates the patient on proper orthotic use, care, and expected adaptation time. This education helps patients understand why certain modifications were made and promotes better compliance with treatment.
6. Follow-Up
After initial adaptation, a follow-up appointment is typically scheduled to review progress and assess outcomes. The practitioner can then make additional refinements if required, ensuring long-term comfort and functionality.
Benefits of Chairside Orthotic Adaptation
- Instant Comfort: Adjustments are made in real time, ensuring the patient leaves the appointment with a comfortable fit.
- Enhanced Accuracy: The orthotic is modified based on live feedback, improving precision and clinical outcomes.
- Improved Compliance: Patients are more likely to wear orthotics that feel comfortable immediately.
- Reduced Turnaround Time: No need to return devices to the lab for remodelling.
- Cost-Effective: Particularly useful for prefabricated orthotics such as Slimflex Orthotics, which are designed for easy modification.
Recommended Orthotics for Chairside Modification
Slimflex Orthotics are one of the most widely used orthotic ranges in Australian clinics for chairside adaptation. They are lightweight, aesthetically professional, and made from high-quality EVA materials that respond well to heat moulding and grinding. Slimflex devices can be easily modified to create semi-bespoke orthoses tailored to the patient’s specific needs—an ideal balance between affordability and customisation.
Common Components Used in Chairside Adaptation
Chairside orthotic modification often involves adding or adjusting components to enhance comfort, improve function or address specific biomechanical issues. Below are some of the most frequently used components and their applications:
Metatarsal Pads
Designed to protect and offload pressure from the metatarsal heads, these pads can be placed precisely based on patient anatomy. They are effective for treating forefoot pain, Morton’s neuroma, and general metatarsalgia. Placement should be customised during fitting to ensure the pad supports the transverse arch without causing irritation.
Valgus Pads
Valgus pads (also called medial arch supports) are inserted inside the shoe or attached to an insole to support the arch and reduce pronation. They are particularly useful for patients with flat feet or fallen arches experiencing medial foot pain. These pads are not typically recommended for diabetic patients due to pressure concentration risks.
Cobra Pads
Cobra pads combine cushioning and medial support, offering a corrective element that helps guide the foot into better alignment. They are commonly used for mild pronation control and arch reinforcement while preserving comfort and flexibility.
Metatarsal Bars
Metatarsal bars provide even pressure distribution across the metatarsal region. They are ideal for relieving metatarsalgia, reducing peak forefoot pressure and enhancing gait comfort. These bars can be shaped or adjusted chairside using basic tools to suit each patient’s needs.
Heel Raises
Heel raises are die-cut EVA pieces designed to elevate the heel. They can be used individually under the insole or bonded to the orthotic for more permanent adjustment. Heel raises are commonly prescribed to correct leg length discrepancies, reduce Achilles tension, or relieve plantar heel discomfort.
Heel Cushions
Heel cushions provide soft pressure offloading for sensitive or bony heel areas. They are often used to relieve pain from heel spurs or bursitis. Materials such as Poron 4708 Medical Blue are popular for their durability, shock absorption, and medical-grade comfort. Heel cushions can be used independently or adhered to orthotic insoles for targeted relief.
Podotech Posting Components
The Podotech posting range includes a variety of wedges, heel posts and forefoot additions designed for quick and precise stabilisation and alignment correction. These components allow for incremental posting degrees to fine-tune the orthotic’s biomechanical control. Best of all, no specialised equipment is required - most modifications can be done with scissors and double-sided tape, making them ideal for fast, efficient chairside work.
Clinical Applications of Chairside Orthotic Adaptation
Chairside adaptation is commonly used to manage and refine orthotic treatment for conditions such as:
- Plantar fasciitis and heel pain
- Metatarsalgia and forefoot pain
- Flat feet and overpronation
- Morton’s neuroma and nerve entrapment
- Leg length discrepancies
- General foot discomfort and shoe-fit issues
In each case, chairside techniques enable immediate comfort improvements, better pressure redistribution, and enhanced long-term compliance.
Best Practices for Chairside Adaptation
- Always document each modification and rationale for clinical traceability.
- Use heat-mouldable, grindable orthotics like Slimflex for best results.
- Involve the patient actively in feedback during fitting and modification.
- Ensure all materials added are skin-safe, durable, and appropriate for intended wear duration.
- Reassess gait and comfort after modifications to verify improvement.
Conclusion
Chairside orthotic adaptation is a highly effective method for improving orthotic comfort, function, and patient outcomes. Through on-the-spot adjustments and immediate feedback, practitioners can achieve tailored results that enhance satisfaction and reduce follow-up issues. Using adaptable orthotic platforms such as Slimflex Orthotics and proven components like Podotech postings, metatarsal pads, and heel cushions, Australian clinicians can provide fast, cost-effective, and professional orthotic solutions that meet the needs of every patient.
How to Choose the Best Podiatry Instruments
Originally written for Algeos.com (UK). A practical, evidence-informed guide for podiatrists comparing instrument categories, steel grades, ergonomics, sterilisation compatibility, clinical performance, cost-of-ownership, and maintenance - plus a quick decision matrix and FAQ.Â
Why your instrument choices matter
Clinical results, practitioner comfort, infection control, and long-term costs all hinge on the quality and suitability of your instruments. The right kit delivers precise cutting, stable grip, predictable handling and resilience to repeated sterilisation. Conversely, bargain instruments can blunt early, corrode, or misalign - adding risk, wasted time and replacement costs.
Core instrument categories (what belongs in a modern kit)
- Nail care: Nail nippers (straight, curved, concave), ingrown nippers, cuticle nippers/scissors, nail files/rasps, drills and burrs for reduction.
- Debridement: Scalpel handles (No. 4), blades (No. 10, No. 15 and podiatry variants), dermal curettes, foot dressers/rasps.
- Soft-tissue & surgical: Tissue and dressing forceps, haemostats/clamps, Iris/Metzenbaum/Lister scissors, probes and lifters.
- Diagnostics: Nail bed probes, calliper/ruler, monofilaments, tuning fork and basic neurovascular tools.
Four pillars of selection
1) Value for money (total cost of ownership)
Price alone misleads. Consider lifetime value: edge retention, resistance to corrosion/pitting, frequency and cost of sharpening, downtime, and replacement intervals. Premium instruments often pay for themselves via longer service life and fewer failures. Build a budget that prioritises high-use, high-impact tools (nippers, scalpel handles, forceps) and economise on low-stress items where appropriate.
2) Durability (materials and build)
The steel and construction methods largely determine longevity.
- Stainless steel grades: For cutting edges, 400-series (e.g., 420/440) offers hardenability and edge retention. For corrosion resistance (handles, non-cutting parts), 300-series (e.g., 304/316L) performs well. Mixed use is common: hardened jaws with corrosion-resistant bodies.
- Heat treatment: Proper hardening and tempering yield sharp, tough cutting edges. Insist on instruments with validated manufacturing and QC.
- Joints & springs: Box-locks and double-springs should be stainless and well-seated; sloppy joints cause misalignment and premature wear.
- Surface finish: Fine polishing and passivation improve corrosion resistance and ease of cleaning.
3) Sterilisation compatibility
Instruments must tolerate repeated steam sterilisation at 121–134 °C. Look for “autoclavable” confirmation, compatible lubricants (“instrument milk”), and avoidance of dissimilar metals that encourage galvanic corrosion. Power-tool accessories and burrs should explicitly state sterilisation parameters. Single-use instruments simplify reprocessing but increase per-procedure cost—many clinics adopt a hybrid model.
4) Clinical performance and ergonomics
Performance is a blend of precise working ends and comfortable, controlled handling across long clinics.
- Ergonomic handles: Contoured or textured grips reduce slip and pinch force.
- Spring action: Quality double-springs on nippers reduce hand strain and improve cadence.
- Balance & weight: Lighter, well-balanced tools reduce wrist fatigue and enhance precision.
- Form factor: Straight versus angled jaws/tips to reach sulci and borders without compromising line of sight.
Instrument-by-instrument guidance
Nail nippers (general, ingrown, concave)
Select jaw geometry for the task: straight or slightly curved for general reduction; fine, slim jaws with offset or anvil profiles for ingrown edges; concave for thicker, mycotic nails. Prefer hardened 420/440 steel cutting edges with smooth box-locks and dependable double-spring action. Test closure alignment (no light gap), smooth hinge travel, and bite consistency. Consider silicone sleeves or knurled handles for extra control.
Scalpel handles & blades
Choose compatible handles (No. 3 for small blades, No. 4 for larger) with positive blade retention and non-slip flats. Blades should be sterile, keen, and consistent—keep a range (#10/#15 and podiatry patterns). Single-use handles can reduce RSI and reprocessing time in high-throughput clinics.
Curettes & dressers
Double-ended curettes (round, oval, spoon) in 1.5–5 mm sizes cover most lesions and nail bed work. Look for rigid, non-flexing shafts, crisp edges, and good tactile feedback. Foot dressers/rasps should be stainless (or diamond-coated) with evenly distributed abrasive and easy decontamination.
Forceps, haemostats, and scissors
Tissue forceps require precise serrations without burring; haemostats need positive ratchets that release reliably. Iris/Metzenbaum scissors should present true tips and even blade contact along the length. Verify that cutting micro-fibres doesn’t snag—an indicator of edge finish.
Drills & burrs
Maintain a selection spanning steel (value, control), carbide (aggressive reduction), and diamond (fine finishing). Stock cones, barrels, buds, and discs across coarse to fine grades. Confirm shank compatibility, RPM limits, and sterilisation guidance. Use extraction and eye/respiratory protection where dust is generated.
Quick decision matrix
| Instrument | Primary Task | Best Material/Spec | Ergonomic Features | Sterilisation Notes | Value Tips |
|---|---|---|---|---|---|
| Nail nippers | General & ingrown reduction | 420/440 cutting jaws - fine box-lock | Double-spring - knurled/contoured grip | Autoclavable - lubricate hinge | Invest premium -Â high utilisation |
| Scalpel handle + blades | Debridement, callus/corn paring | Stainless handle - sterile blades (No 10 or No. 15) | Non-slip flats - secure blade fit | Handles autoclavable - blades single-use | Use dispenser packs - mix sizes |
| Curettes | Lesion and nail bed work | Rigid stainless - crisp spoon edges | Balanced shaft - tactile feedback | Ultrasonic clean - steam sterilise | Buy set of sizes - mid-premium |
| Forceps/haemostats | Tissue handling, haemostasis | Corrosion-resistant stainless | Positive ratchet - precise serrations | Avoid residue in teeth/ratchets | Premium pays off in reliability |
| Scissors (Iris/Metz/Lister) | Soft tissue, dressings, suture | Hardened blades - true tips | Smooth action - light, balanced | Protect tips - case storage | Plan periodic sharpening |
| Drill burrs (steel/carbide/diamond) | Reduction & finishing | Match grit to task - validated shanks | N/A | Check RPM/steam compatibility | Hold mixed set - replace on wear |
Brand and sourcing considerations
- Reputation & certification: Prefer medical suppliers with ISO 13485 processes and CE/UKCA or FDA compliance information. Transparent steel grade, hardness, and sterilisation data are green flags.
- Range depth: Brands that offer multiple jaw profiles, sizes, and spare parts (springs, screws) simplify standardisation.
- Service & warranty: Access to sharpening, calibration, and fair warranties reduces lifecycle cost.
- Trials: Where possible, order one of each candidate instrument to assess grip, balance, and cutting feel in your own workflow.
Set-building strategy (new vs. established clinics)
Newly qualified or new clinics
Start with a robust core: premium general nipper, ingrown nipper, No. 3 handle with mixed blades, two sizes of curette, tissue forceps, Iris scissors, Lister scissors, haemostat, dresser/rasp, and a compact burr set. Add duplicates of high-turnover tools to maintain throughput during reprocessing. Standardise where feasible to minimise training and inventory complexity.
Established practices
Audit annually. Replace any instrument with persistent misalignment, corrosion, or unreliable action. Upgrade high-use items first to ergonomic variants (double-spring nippers, contoured forceps). Expand burr assortments to reduce chairside time and improve finish quality. Consider hybrid workflows (mixing reusable and single-use) to match patient risk categories and clinic tempo.
Maintenance that protects your investment
- Immediate pre-clean Rinse/soak promptly to prevent bioburden drying - separate sharp tips with guards.
- Ultrasonic clean Use compatible enzymatic detergents - open hinges/ratchets so solution reaches joints.
- Dry and lubricate Dry thoroughly - apply instrument milk to joints and springs to prevent stiffness and rust.
- Inspect & protect Check edge integrity, jaw alignment, ratchet function; store in trays/cases to avoid knocks.
- Sterilise correctly Follow manufacturer parameters (time/temp) - document cycles - use tip guards as needed.
- Sharpen & rotate Schedule periodic sharpening for nippers/scissors - rotate sets to balance wear and maintain clinic flow.
Bottom line
Choose instruments on the strength of their steel, construction, ergonomics, and sterilisation resilience - then judge value over the full life cycle. Prioritise premium quality for high-use items, standardise where possible, and protect your investment with disciplined maintenance. The result: safer care, smoother clinics and better long-term economics.
