Progressive cartilage breakdown changes how forces move through affected finger and thumb joints. As cartilage becomes less effective, load distribution shifts toward surrounding structures, while subchondral bone remodels. Osteophytes, or bony overgrowths, may develop, and episodic synovial inflammation can add swelling and stiffness. Together, these changes can reduce grip and pinch performance, linking structural progression with functional limitations.
Symptoms may fluctuate when episodic synovial inflammation accompanies the underlying structural changes. This inflammation can produce periods of swelling and stiffness, even though the broader condition also involves progressive cartilage breakdown and bone remodeling. Pain and stiffness may therefore affect hand use differently across episodes, while reduced grip or pinch strength reflects the functional impact.
Distinguishing hand osteoarthritis from inflammatory arthritis requires more than symptoms alone. Clinicians combine the patient’s symptom history with physical examination and, when indicated, radiographs. This combined assessment helps identify whether the presentation fits degenerative joint disease or suggests inflammatory arthritis, supporting a more appropriate care plan.
Assessment begins with symptom history and a physical examination of the hand, including the affected finger or thumb joints and their functional effects. Radiographs may be added when indicated. These sources of information help clinicians evaluate pain, stiffness, swelling, and impaired hand use, distinguish osteoarthritis from inflammatory arthritis, and guide treatment decisions.
Initial care focuses on preserving function rather than addressing symptoms alone. Education helps patients understand the condition, while therapeutic exercise supports hand use. Activity modification can reduce aggravating demands, and splinting may provide additional support. Symptom-relief strategies can be incorporated as needed, with the overall approach aimed at maintaining grip, pinch, and daily hand function.
Injections or surgery are considered for selected cases rather than as routine first steps. The decision follows clinical assessment and the individual’s symptoms, functional limitations, and response to approaches such as education, exercise, activity modification, splinting, and symptom relief. These options may be discussed when preserving hand function requires additional intervention.
