Causes:

Aging:
Over time, natural wear and degeneration of cartilage tissue in the joints can occur.
Genetic Factors:
Individuals with a family history of osteoarthritis may be more prone to this condition.
Overuse:
Overuse of the hand and wrist joints, especially repetitive movements or weight lifting, can contribute to arthritis.
Wrist Injuries:
Wrist injuries, especially bone fractures or ligament injuries, can lead to osteoarthritis.
Metabolic Factors:
Obesity or metabolic diseases can increase the load on the joints and cause arthritis.

Non-Surgical Treatment Methods:
Pain Management:
Painkillers and anti-inflammatory drugs can help control joint pain.
Physical Therapy and Exercise:
Special exercise programs with a physiotherapist can improve joint flexibility and increase muscle strength.
Rest and Joint Protection:
Resting and protecting the joint can help reduce pain.
Orthosis Use:
Specially designed wrist supports or orthotics can relieve pain by supporting the joint.
Hot and Cold Treatment:
Hot or cold applications can relieve pain and swelling.

Surgical Treatment Methods:
Surgery is usually considered in cases that do not respond to non-surgical treatments. Surgical options may include joint cleaning (arthroscopy), joint fusion (arthrodesis), or joint replacement (arthroplasty).
