Build FAQ: subsidence, knot-stack irritation, pricing, stress-risers, retrograde vs. antegrade, kit configuration, trade-in requests.
Target surgeons effectively (primary, revision, conversion strategies).

Product Cheat-Sheet

1 Arthrex Mini TightRope CMC

Core concept: Double-button, FiberWire suture suspends $1^{\text{st}}$ MC to $2^{\text{nd}}$ / $3^{\text{rd}}$ interspace.
Technique evolution
- Original $2.7\,\text{mm}$ drill → mid-shaft fractures in osteopenic $2^{\text{nd}}$ MC (Journal Hand 02/2012).
- Redesign: $1.1\,\text{mm}$ guide pin stepped to $0.86\,\text{mm}$ nitinol loop; eliminates large tunnel.
Clinical evidence: most published data among suspension-plasty options.
Benefits
- Cortical button fixation both ends
- Straight, reproducible shot; minimal OR time vs. LRTI
- Early ROM; no “bridge-burning” (future LRTI still possible)
Drawbacks / failure modes
- Thick titanium buttons; large knot stack with $\approx1\,\text{cm}$ tails → dorsal soft-tissue irritation (esp. thin post-menopausal females)
- Midline accuracy critical; off-center placement palpable
- Occasional need for removal/revision or retrograde flip to hide knot

2 Arthrex FiberLok CMC Hammock

Fully disposable indexed kit (thumb vs. index versions).
Construct: Tape spans like a hammock; distal fixation in $2^{\text{nd}}$ MC cortex via small soft-anchor; proximal fixation via $3.5\,\text{mm}$ fork-tip SwiveLock.
Price: $\$1{,}895$ each; using two → >\$3{,}700 (typically hospital only).
Rationale: solve internal-brace subsidence by adding cortical fixation.
Weaknesses
- Long construct; high "fiddle-factor" drilling sequence.
- Fork-tip SwiveLock: $3.5\,8.5\,\text{mm}$ (only $\approx4\,\text{mm}$ thread engagement) → tape slippage/pull-out; documented early subsidence.
- Still requires large $3\text{–}3.5\,\text{mm}$ pre-drill into $1^{\text{st}}$ MC.

3 Arthrex CMC Internal Brace

Knotless tape + (optional) $\le2\,\text{mm}$ wide $\approx4\,\text{cm}$ APL autograft.
Same $3.0$ or $3.5\,\text{mm}$ fork-tip SwiveLock fixation; fully radiolucent.
Pros: Single kit; self-tensioning (tape glides under fork tips).
Cons: Same subsidence issue (tape slips past 2-thread hold); surgeons nervous drilling $3.5\,\text{mm}$ tunnel in $2^{\text{nd}}$ MC.

4 Arthrex Economy LRTI Kit

4-mm tunnel + FCR tendon transfer; still $\approx65\%$ of ASSH membership.
Advantages: low implant cost ( $\$400\text{–}600$ ).
Disadvantages: longer OR, donor-site morbidity, delayed ROM.

5 Acumed AccuSynch Nautilus Mini (ASK Mini)

Knotless, low-profile double-button construct; preloaded on disposable inserter.
Distinctives vs. TightRope
- Smaller titanium buttons; countersink inside $2.3\,\text{mm}$ tunnel → minimal prominence.
- No external knot stack (cinch lock inside thumb side).
- Cortical fixation both ends (same “button suspension plasty” literature applies).
Instrument SKUs
- Inserter + suture/anchor/button
- Single guidewire & $2.3\,\text{mm}$ cannulated drill
Current IFU: antegrade wire/drill only (retrograde addendum pending regulatory review).

Surgical Technique Pearls & Imaging

Position & Tension Check

Place freer elevator between $1^{\text{st}}/2^{\text{nd}}$ bases while tightening – spacer prevents overtension.
Cycle ROM before final lock (TightRope can re-tie; ASK Mini cannot back-off):
- Radial abduction
- Palmar abduction
- Thumb opposition
- Circumduction
Desired resting posture: thumb flat, neutral; avoid “tucked-under” (overtension).

Fluoro Landmarks

Shenton’s line of the hand: smooth arch connecting $2^{\text{nd}}–5^{\text{th}}$ MC bases; suspended $1^{\text{st}}$ should follow contour.
- Drop ↓ = undertension (subsidence)
- Proximal ↑ / folded under palm = overtension
Keep trapezium in situ during drilling for height reference (optional; especially Eaton III–IV cases).

Numerical & Technical References

Drill sizes

SwiveLock fork-tip anchor: $3.5\,8.5$ mm (only $\approx2$ threads = $\approx4\,\text{mm}$ engagement)
FiberLok price: $\$1{,}895$ each; 2 implants >\$3{,}700
LRTI kit cost: $\$400\text{–}600$

Sales Positioning & Targeting Strategy

Immediate wins
- Current Mini TightRope users frustrated by knot complaints.
- FiberLok/Internal-Brace surgeons experiencing early subsidence.
Revision niche
- Market ASK Mini as revision option after failed LRTI or other implants (small tunnels, no bridges burned).
Primary conversion
- Younger surgeons; value shorter OR and evidence for early ROM.
- Emphasize $30\text{–}40\%$ faster procedures vs. LRTI (per Dr. Garcia at NSM).
Objections & Answers
- Micro-fracture risk $2^{\text{nd}}$ MC ➔ Highlight smaller $2.3\,\text{mm}$ drill + option for retrograde wire to ensure mid-shaft trajectory.
- Need for drill guide/spacer ➔ Freer elevator technique; future instrumentation under review.
- Competitive trade-in demands ➔ Company policy = no direct trade-in; escalate to Strategic Accounts for pricing solutions.

Pricing / Kit Logistics

ASK Mini sold as two SKUs
1. Disposable inserter w/ pre-loaded construct
2. Guidewire + drill
Arthrex kits: always all-inclusive; CMC-specific version up-charges $\approx\$300$ for trapeziectomy tool.
SwiveLock + tape = single kit (internal brace & FiberLok) → costly for ASC; ASK Mini positioned as cost-efficient single-implant solution.

Regulatory & Future Updates

Retrograde surgical-technique addendum, drill guide/spacing block, and additional marketing collateral under development (post-launch, pending LMR).
Evidence Matters sheet + Dr. Desai video releasing in coming weeks.
Reps encouraged to collect TruShot (ConMed) intel; competitive landscape becoming crowded (Dunamis, SkeletalDynamics, etc.).

Frequently Asked Questions (summarised)

Does ASK Mini allow early motion? Yes—identical clinical rationale to published “button suspension-plasty” literature.
Can surgeon remove implant later? Yes; cortical buttons easily extracted; bone tunnels minimal.
Any published data on FiberLok complications? Nothing peer-reviewed yet; field reports of subsidence common—ask surgeon directly.
ASC worried about existing inventory? Acumed currently no trade-in; discuss volume-based pricing with Strategic Accounts.
Spacer/drill guide included? Not in v1; use freer elevator; design team assessing add-ons.
