Condition
Thumb CMC Osteoarthritis: Options and What the Evidence Actually Shows
Basal thumb arthritis limits pinch. Splints and therapy go a long way.
Anatomy and clinical context
The thumb CMC joint is a common OA site. Patients lose pinch strength and have pain opening jars or keys.
Therapy and splinting often delay surgery for years.

The standard-of-care ladder
Conservative care first, then injections, then surgery when indicated. Cell therapy belongs in that conversation — not above it.
- Step 1
Conservative care
Splinting, hand therapy, activity modification.
- Step 2
Injections
Corticosteroid or orthobiologic injectates for flares.
- Step 3
Surgery
Trapeziectomy ± soft-tissue procedures for advanced disease.
Where cell therapy fits
Small-joint regenerative evidence is limited. Surgery remains reliable for end-stage CMC OA.
- Long nonoperative runway for many patients.
- Injectates are symptom tools.
- Banking supports whole-body optionality more than CMC-specific care.

Why dose and donor age change the picture
The trials that disappoint used unexpanded cells from older donors.
The ones that work used expanded cells at therapeutic dose. Dose is the variable — and dose is what expansion buys you. Potency is what your age buys you.

Cells work at dose.
A same-day draw yields a small, uncounted, unexpanded fraction. Expansion turns one draw into many doses.

Potency is age-dependent, and it is a one-way door.
Your MSCs at 35 are not your MSCs at 55. Banking is the only mechanism that makes 35-year-old cells available to a 55-year-old.

Expansion is what makes the bank a supply, not a souvenir.
Bank once, expand repeatedly, across a treatment course rather than a single shot. Culture expansion for Forever Labs members is rolling out — starting with selected states as our Florida cGMP lab comes online.

We supply cells; they practice medicine. Forever Labs does not treat conditions — your physician owns the clinical relationship.
Two next steps — equal weight
Forever Labs does not treat conditions. Your physician owns the clinical relationship. We bank cells and, as expansion rolls out, help make dose possible.
