SPORLASTIC x Thetis Medical
The missing night-time product for Achilles rupture recovery.
SPORLASTIC already protects ATR patients by day with SP AIR WALKER. Thetis has the proven night splint patients need — and your textile manufacturing expertise is exactly what it takes to scale it.
Achilles rupture · SPORLASTIC
SP AIR WALKER for the day. Thetis for the night.
SPORLASTIC already immobilises Achilles ruptures with the SP AIR WALKER range and adjustable heel wedges. Thetis adds the missing night-time product — lightweight, patented, and purpose-built for sleep, rest, and hygiene when the boot comes off.
Day · immobilisation
SP AIR WALKER PLUS
Lower-leg and foot brace with dual air chambers, removable liner, and heel wedge for defined plantarflexion — already indicated for Achilles tendon rupture.

Day · plantarflexion
Removable heel wedge
SPORLASTIC already adjusts equinus position through the walker wedge system. Splint sales sit on the same ATR pathway — the same customer, the same rep visit.

Night · rest & sleep
Thetis Achilles Splint
A patented ~200 g splint that maintains plantarflexion when the boot is off at night, at rest, or during hygiene — the product patients search for when the boot fails them.
Routes to market
Germany already reimburses night splints — but not for Achilles rupture
Sanitätshäuser can prescribe a generic plantar fasciitis night splint alongside the SP AIR WALKER on separate Hilfsmittelverordnungen. The reimbursement route is open — the listed devices are not.
🇩🇪 GKV · Produktgruppe 23 Orthesen/Schienen
Important
They just reverse the wedge.
Same PG 23 code. Wrong angle for ATR. Still too bulky — sleep barely improves.
23.03.01 Fußorthesen zur Immobilisierung · Produktart 23.03.01.0 Fußlagerungsorthesen
Manufacturers list dorsal night splints under these positions when bundling with walker boots. Examples from the Hilfsmittelverzeichnis:
23.03.01.0007
DARCO NightSplint®
Fußlagerungsorthese · Fasciitis plantaris / postoperative Ruhigstellung
23.03.01.0009
DARCO Body Armor® Night Splint
Dorsale Fußlagerungsorthese · plantare Faszie / Achillessehnenschwäche
23.03.01.0019
PROCARE® Plantar Fasciitis Night Splint
Marketed for simultaneous Verordnung with Aircast® walker — hygiene & wound healing, not ATR plantarflexion
23.03.01.0023
Universal Plantarfasziitis Orthese (UFO)
Generic dorsal night splint · plantar fasciitis indication
Wrong angle for ATR
Listed splints hold the foot in dorsiflexion to stretch the plantar fascia — the opposite of the ~30° plantarflexion Achilles rupture healing requires.
Still too bulky to sleep
Patients swap the boot for a slightly lighter splint — but it remains a rigid dorsal shell with straps. Sleep quality barely improves.
Workaround, not a category
Reps bundle an existing PG 23 code with the walker. No Hilfsmittel entry exists for a purpose-built ATR night splint — yet.
SPORLASTIC could use the same reimbursement channel with the right device: lightweight, ~30° plantarflexion, and designed only for Achilles rupture rest and sleep.

Great product to use about five or six weeks into a ruptured Achilles injury instead of the heavy large clumsy dirty boot they pit you in. Keeps the foot in a great healing position and you get a good nights rest.

Verified purchasegute Alternative zur Orthese
Eine gute und leichte Alternative wenn man die schwere Orthese nicht im Bett tragen möchte. Leider drückt das Teil ziemlich auf den Vorderfuss, dadurch behält man zwangsläufig die richtige Fußstellung ( was wohl so gedacht ist). War sehr zufrieden.

Verified purchaseComfortable and fit great
Perfect for sleeping!! I have a very injured Achilles tendon and this makes sleeping much better. It’s comfortable and fit perfectly. Also stayed in place while sleeping. I felt like my ankle was supported better in this than the boot I have.

Proof
Surgeons say yes
Leading foot and ankle surgeons recommend the splint for night-time use — the problem the walking boot cannot solve.
-
“A game-changer in my practice. The splint's design prioritizes both comfort and functionality, enabling controlled, progressive recovery.”
Dr Robbie Ray
Foot and Ankle Surgeon
-
“When I tore my own Achilles tendon, the hardest part was wearing the hospital boot in bed. This splint is certain to improve the recovery experience for patients.”
Mr James Davis
Past President of the British Orthopaedic Foot and Ankle Society
-
“Makes complete sense to use something like this and I highly recommend this product. Comfort and usability all round.”
Mr Andy Roche
Foot and Ankle Surgeon
-
“Worth every penny as it stops the misery of trying to get good nights sleep in an uncomfortable boot!”
Mr Ian Gill
Foot and Ankle Surgeon
Manufacturing fit
Capabilities worth exploring together
Thetis brings patient demand, IP, and regulatory clearance. SPORLASTIC brings orthopaedic plastic design, textile depth, assembly capability, and an existing ATR pathway. We would welcome your team's view on where — if anywhere — this adds value.
Concept: Thetis splint with SPORLASTIC generative-design shell — same pathway, premium manufacture
Plastic shell design
The splint depends on a rigid dorsal shell for plantarflexion lock — the same class of problem as walker shells, heel wedges, and brace hardware. Your experience in orthopaedic plastics — including lightweighting and generative design — could be relevant if you chose to refine the shell.
Textiles & comfort
Liners, straps, and overnight skin contact sit alongside the shell. Your flat knit, intarsia, and latex-free fabric expertise could be relevant if you chose to refine the soft-goods side of the product.
SP AIR WALKER pathway
You already immobilise ATR patients by day with plastic-and-textile products you manufacture in-house. A night splint might sit alongside that offer — we would need your read on channel and plant fit rather than assume it.
