Do you know what rhizarthrosis is and how to treat it?

The treatment of degenerative hand and wrist pathology, Rizarthrosis.

 

Rhizarthrosis, osteoarthritis of the first metacarpal joint with the trapezius bone (base of the thumb) is considered the most disabling degenerative pathology in the joints of the hand and wrist.

 

The importance of this pathology is in the functional deficit that it causes and in its high frequency, which may be a cause of chronic socio-occupational disability and have a significant impact on activities of daily life.

 

On the other hand, the trapeziometacarpal joint is one of the most common locations for arthrosis that postmenopausal women have. 33% of this group suffer a painful picture. Men suffer less, being 1 from 10 women and it is the one that causes the most surgical processes.

The symptom is a pain in the base of the thumb that extends to the forearm, and is pronounced when performing certain maneuvers, causing loss of strength and functional disability and in certain cases a deformity of the thumb.

 

To confirm the diagnosis, it is important to carry out a radiological examination that will help us assess the degree of involvement of the trapezius and confirm the need or not for surgical treatment. The procedure aims to make pain disappear, while restoring finger movement. 

 

How to treat rhizarthrosis?

 

Trapeciometacarpal arthrodesis

 

The altered joint surfaces should be removed, fixing them in the proper position. We use a splint and its main disadvantages are loss of joint mobility, inability to flatten the palm, and lack of skill in fine movements.

 

Dynamic Interposition-Suspension Arthroplasty

 

This technique tries to avoid complications that may produce an implant, and in turn provide good stability to the finger bone. The main advantages are the significant improvement of the mobility of the finger and the recovery of force to perform tweezers and grips.

 

Total replacement prosthesis arthroplasty

 

It completely replaces the two components of the joint. It produces stability, keeping the movement of the joint very close to normal. In a study carried out in the USA, 196 fingers were treated with this pathology, it was found that 53% of the patients did not have any post-operative pain. 32% showed a clear improvement with occasional pain. 12% obtained improvement in their symptoms at rest. And only 3 patients continued to have pain after surgery. Post-operative recovery does not exceed six weeks of immobilization. They are non-invasive treatments that make the patient not exceed 24 hours of stay in the postoperative period.
