1. What is CMC osteoarthritis?
Degenerative changes develop in the trapeziometacarpal joint between the thumb and wrist. Pain, reduced grip strength, and joint deformity over time may be observed.
How can laser help?
The goal is to reduce pain and facilitate hand exercises and daily use. Laser should not be used with the claim that it reverses structural osteoarthritis in the joint.
The role of 980 nm
It can be used in the superficial joint and periarticular tissues.
The role of 1470 nm
Because the joint is very superficial, it is anatomically accessible; however, there is no clinical efficacy data specific to 1470 nm, and the superficial thermal load must be controlled carefully.
What does the scientific evidence say?
Level of evidence: C. Although general laser data in the field of orthopedic pain and osteoarthritis are supportive, direct data specific to thumb CMC osteoarthritis are insufficient.
Our approach in our Bodrum clinic
In our Bodrum clinic, CMC osteoarthritis, De Quervain’s tenosynovitis, and other tendon/joint causes are differentiated in thumb base pain. If laser is considered, it is planned together with splints, joint protection strategies, and hand exercises.
Frequently asked questions
Why does pain occur when opening a jar?
The thumb base joint is exposed to high loads during strong gripping; in CMC osteoarthritis, this movement is typically painful.
Does laser eliminate osteoarthritis?
No. The goal is to support symptoms and function.
