What is Rhizarthrosis ?

Rhizarthrosis, also known as basal joint arthritis, is a degenerative joint condition that affects the base of the thumb where it meets the wrist. The condition is characterized by the wearing down of the cartilage that cushions the joint, leading to pain, stiffness, and decreased range of motion.


Rhizarthrosis is a common condition, particularly among women over the age of 50. It can be caused by a variety of factors, including overuse of the joint, injury, or genetic factors. Certain occupations or activities that require repetitive use of the thumb and wrist, such as knitting or typing, may increase the risk of developing Rhizarthrosis


Symptoms of Rhizarthrosis may include pain and tenderness at the base of the thumb, stiffness and decreased range of motion, swelling and inflammation, and weakness in the thumb. Treatment options may include medications, physical therapy, splints or braces, and in severe cases, surgery.


The treatment of rhizarthrosis generally focuses on reducing pain and improving hand function. Here are some of the most common treatment options:

  1. Non-Surgical Treatments:
  • Resting the affected hand and avoiding activities that cause pain
  • Applying ice packs to the affected area
  • Taking over-the-counter pain medications, such as acetaminophen or nonsteroidal anti-inflammatory drugs (NSAIDs)
  • Wearing a splint or brace to support the thumb and limit its movement
  • Doing hand exercises or physical therapy to improve range of motion and strength
  1. Surgical Treatments:

If non-surgical treatments do not provide sufficient relief, surgery may be recommended. The most common surgical procedures for rhizarthrosis include:

  • Joint fusion: This involves removing the damaged joint surfaces and fusing the bones together with screws or pins.
  • Joint replacement: This involves removing the damaged joint and replacing it with an artificial joint made of metal, plastic, or silicone.
