Abstract

Objective: The study was aimed to compare the impact of thumb base osteoarthritis (TBOA) on pain, function, and quality of life in patients with erosive or non-erosive hand osteoarthritis (HOA).

Methods: This observational retrospective study included 232 patients: 64 with erosive HOA (EHOA) and concomitant TBOA, 36 with isolated EHOA, 97 with non-erosive HOA (non-EHOA) and TBOA, and 35 with isolated non-EHOA. Hand pain by a visual analogue scale (VAS), Functional Index for Hand Osteoarthritis (FIHOA) score, Health Assessment Questionnaire (HAQ), the Medical Outcomes Study 36-Item Short Form (SF-36), and the possible correlations between VAS and FIHOA with radiological score were assessed.

Results: No differences were found between EHOA with TBOA and isolated EHOA in VAS and FIHOA scores; opposite, there was a significant difference in VAS (p < 0.01) and FIHOA (p < 0.001) between subjects with non-EHOA and TBOA and patients with only non-EHOA. VAS and FIHOA values resulted slightly higher in patients with EHOA and TBOA vs non-EHOA and TBOA; they were significantly more elevated in EHOA and TBOA group compared to isolated non-EHOA (p ≤ 0.001) and in isolated EHOA vs isolated non-EHOA (p < 0.01 and p < 0.001, respectively). HAQ, SF-36 resulted significantly better in isolated non-EHOA patients compared to the other groups. Finally, we observed a significant correlation between FIHOA and all the Kallman scales in EHOA patients with TBOA and between FIHOA and Kallman's thumb score in non-EHOA-TBOA group.

Conclusions: EHOA has a more severe clinical burden than non-EHOA; the presence of TBOA appeared an important determinant of pain and disability in non-EHOA.Key Points• Each subset of HOA can have a different impact on pain and functionality, with EHOA determining more severe effects on hand symptoms and disability than non-EHOA.• The presence of TBOA appeared an important determinant of pain and disability in non-EHOA, but not in EHOA.• Our findings support the need for an individualized therapy for each phenotype of hand osteoarthritis.
