Osteoarthritis of the fingers: when pain becomes a handicap

Osteoarthritis of the fingers is a chronic condition that mainly affects the distal interphalangeal (DIP) and proximal interphalangeal (PPI) joints, but can also affect the metacarpophalangeal joints. This progressive wear and tear of cartilage leads to pain, stiffness and sometimes visible deformity. It is often associated with age, repeated microtrauma or genetic predisposition.

What are the signs?

• Morning stiffness, with a "locked fingers" sensation

• Pain from pressure or repetitive movements

• Appearance of visible nodules/"small bumps" (Heberden's nodules on IPD, Bouchard's nodules on IPP)

• Progressive deformation of the fingers and loss of mobility

• Difficulty performing fine gestures (buttoning, writing, using a smartphone)

What are the solutions?

Treatment depends on the severity of symptoms and their functional impact.

• Joint rest and modification of daily movements

• Wearing flexible or rigid orthoses to stabilize joints

• Physiotherapy or occupational therapy to maintain mobility

• Corticosteroid infusions for inflammatory flare-ups

• Regenerative medicine +++: injections of platelet-rich plasma (PRP)

• Surgery (arthrodesis or arthroplasty -prostheses-) in advanced cases, to relieve pain and restore function

A specialized consultation provides a precise diagnosis using X-rays and customized therapeutic support.
