At the Institute of Regenerative Orthopedics & Sports Medicine (IROSM), Dr. Jorge Gonzalez, MD at IROSM in Fort Lauderdale evaluates thumb pain with an exam, X-rays and in-office ultrasound, and offers non-surgical care for appropriate candidates.

Minimally Invasive Treatment for Thumb Joint Arthritis | Dr. Jorge Gonzalez, IROSM
Important Notice from IROSM: Thumb arthritis care is a customized medical treatment led by Dr. Jorge Gonzalez. A thorough clinical evaluation at IROSM in Fort Lauderdale determines whether splinting and hand therapy, an image-guided injection, or a surgical referral best fits your thumb.

What Is Thumb Arthritis (CMC Osteoarthritis)?

Thumb arthritis is wear of the cartilage in the carpometacarpal (CMC) joint at the base of the thumb. This joint sits where the thumb bone meets a small wrist bone called the trapezium. It is also called basal joint arthritis or CMC osteoarthritis (CMC OA).

The CMC joint lets the thumb swivel and pinch, so it takes a lot of force every day. Over time, the cartilage can thin and the joint can loosen, which causes pain and weakness. Thumb arthritis is more common in women and after age 50. Learn more about degenerative osteoarthritis. Dr. Gonzalez evaluates thumb arthritis at IROSM in Fort Lauderdale to confirm the diagnosis and its stage.

Symptoms of Thumb Arthritis

Thumb arthritis symptoms usually start as an ache at the base of the thumb during use. Common signs include:

  • Pain when pinching, gripping or twisting
  • Trouble opening jars, turning keys or buttoning
  • Swelling and tenderness at the base of the thumb
  • A weaker pinch or grip
  • A bump or enlarged look at the base of the thumb
  • Stiffness, especially in the morning

Other conditions can cause similar pain. De Quervain’s tenosynovitis causes pain on the thumb side of the wrist, and a trigger thumb causes catching or locking. An exam at IROSM in Fort Lauderdale helps tell them apart.

How Thumb Arthritis Is Diagnosed at IROSM

Diagnosis of thumb arthritis at IROSM in Fort Lauderdale starts with your symptoms and a hands-on exam. Dr. Gonzalez presses on the base of the thumb and gently moves the joint to check for pain, grinding or looseness.

A simple hand X-ray is usually enough to confirm CMC arthritis and show how advanced it is. In-office ultrasound for orthopedics and sports medicine lets Dr. Gonzalez look at the joint lining and nearby tendons during your visit. CT scans and MRI are rarely needed.

Thumb Splints and First-Line Thumb Arthritis Treatment

Many people with thumb arthritis start with simple steps that rest and support the joint:

Thumb Splint or Brace

A thumb splint holds the base of the thumb steady and may ease pain. It is often worn at night and during tasks that cause pain. Your doctor or hand therapist can help you choose the right fit.

Hand Therapy and Exercises

A hand therapist can teach exercises that support the joint and show you easier ways to grip, pinch and lift.

Everyday Tools and Changes

Wide-grip pens, jar openers, key turners and lever door handles take strain off the thumb during daily tasks.

Ice, Heat and Medicine

Ice after activity, warmth for morning stiffness, and short-term anti-inflammatory medicine may ease flare-ups.

Dr. Gonzalez at IROSM in Fort Lauderdale will suggest which first-line steps fit your thumb and your daily activities.

Thumb Arthritis Injections at IROSM in Fort Lauderdale

When splints and therapy are not enough, an injection may be considered. At IROSM in Fort Lauderdale, thumb joint injections are placed with ultrasound guidance so they reach the small CMC joint. Read how image-guided injections improve accuracy.

  • Corticosteroid injection: may calm inflammation and ease pain for a period of time.
  • PRP injection: made from a small sample of your own blood. See PRP therapy in Fort Lauderdale.
  • Orthobiologic injection: uses your own (autologous) cells prepared in our Advanced Regenerative Lab. See orthobiologic treatments.

Dr. Gonzalez explains this approach in more detail in minimally invasive treatment for thumb joint arthritis. Thumb arthritis injections are not right for every patient, research results are mixed, and results vary. Candidacy is decided at an in-person evaluation.

When Is Thumb Arthritis Surgery Considered?

Surgery for thumb arthritis is usually considered when pain and weakness continue despite splinting, therapy and injections. Common operations include:

  • Trapeziectomy: removal of the worn trapezium bone, sometimes with a tendon used to support the thumb.
  • Joint fusion: joins the bones so the joint no longer moves, which may suit people who need a strong grip.
  • Joint replacement: replaces the worn joint with an implant.

Recovery after thumb surgery usually includes a cast or splint and hand therapy. If surgery is the better fit for your thumb, Dr. Gonzalez will explain why and help with a referral.

What the Research Says About Thumb Arthritis Injections

  • PRP compared with a steroid injection: In a randomized trial of people with early to moderate thumb (CMC) arthritis, the group treated with two PRP injections reported less pain and better hand function at 12 months than the group treated with corticosteroid injections. Malahias MA, et al. Platelet-Rich Plasma versus Corticosteroid Intra-Articular Injections for the Treatment of Trapeziometacarpal Arthritis: A Prospective Randomized Controlled Clinical Trial. Cartilage. 2021;12(1):51-61. View the study.
  • PRP compared with placebo: A 2025 double-blind trial found that a single PRP injection did not reduce thumb pain more than a placebo injection over 6 months. Evidence for PRP in thumb arthritis is still developing, and results may depend on the number of injections and the stage of arthritis. Evans K, et al.
