What is basal joint arthritis?

Wear and tear of the joint cartilage is a wear and tear of the joint cartilage that occurs insidiously, usually unnoticed at first. Wear and tear of the thumb saddle joint, also known as rhizarthrosis, can be very painful. In most cases, the cause is unknown and targeted therapy is not possible. If the cartilage protective layer is lost, the load is no longer dampened and evenly distributed.
Unfortunately, cartilage damage cannot be completely reversed to date. At the beginning, the forces acting on the joint can be buffered by special thumb splints. Ibuprofen, diclofenac or the vegetable frankincense extract H15 are frequently used because they have an anti-inflammatory and analgesic effect. If these measures no longer help, a surgical intervention can be useful. Which of the various surgical treatments (e.g. fat stem cell treatment, denervation, resection arthroplasty) is the right one for you depends on your requirements and the degree of wear and tear.
Resection arthroplasty is the procedure with the most experience. The worn large polygonal bone is removed via a small access on the outside of the ball of the thumb and the joint is stabilized with suture techniques.

How can you prepare for the procedure?

  • All your questions about possible complications and alternative treatments should be answered in advance.
  • Keep nicotine and alcohol consumption to a minimum!
  • Blood-thinning medication (e.g. ASS, Thomapyrin®) must be discontinued at least 10 days before the operation after consultation with your doctor.
  • Vitamin preparations (A, E) and food supplements (omega-3 fatty acids, St. John's wort preparations, etc.) must be discontinued at least 4 weeks before the operation.
  • Surgery limits the ability to travel by air. Therefore, do not plan any professional or private air travel during the 6 weeks after the operation!
  • Lay down ice cubes or cooling pads at home ready to cool the skin after the operation!

How is the procedure performed?

  • The outpatient operation is performed under arm or general anaesthesia and lasts about 30 minutes.

What do you need to keep in mind after the procedure?

  • The raising and cooling of the hand in the first 72 hours is very important.
  • Immobilization is recommended for a total of 4 weeks (Palmare forearm wrist thumb splint with free interphalangeal joint in opposition and abduction of the thumb for 14 days; then middle hand thumb splint with release of the interphalangeal joint for a further 14 days).
  • Complete fist closure and finger stretching exercises should be performed several times per hour. All joints outside the splint must be fully moved several times an hour.
  • A silicone capillary drainage is removed on the 1st postoperative day if necessary, the skin threads are removed after 10 to 14 days.
  • Postoperative clinical check-ups are recommended on the 1st and 3rd postoperative day and after 1 and 2 and 4 weeks.
  • The independent scar massage from the 3rd postoperative week with moisturizing ointment (e.g. Bepanthen® wound and healing ointment, Linola® fat cream) helps to create inconspicuous soft scars.
  • A full load is possible from the 12th postoperative week.
