Objectives/Interrogation: Trapeziectomy is used to treat osteoarthritis of the carpo-metacarpal joint. Depression associated with osteoarthritis is a well-established phenomenon and dissatisfaction may be linked to the patient's mood pre-operatively. The objective of this study is to explore the association of pre-operative anxiety and depression with functional outcome for thumb pain and function before and after trapeziectomy.
Methods: Twenty-two consecutive patients undergoing trapeziectomy completed pre-operative Hospital Anxiety and Depression Scale (HAD) and quickDASH (DASH) pre and post-operatively. Median results are reported. Non-parametric statistics were used to evaluate the relationship between variables.
Results and Conclusions: Twenty-two patients, 18 female and 4 males, with a median age of 63 (IQR 57, 66) years were recruited to the study. Median follow up was 38 months. Fourteen right and 8 left trapeziectomies were performed. Median pre-operative DASH was 58 (IQR 43, 70) and 18.1 (IQR 4.5, 35) post-operatively (p < 0.001).
Fourteen participants showed evidence of anxiety or depression: 6 mild, 5 moderate and 3 severe.
DASH improved by 36 points with or without evidence of anxiety or depression. Pre-operative DASH increased with HAD (p = 0.02) and across HAD categories: none 52, mild 49, moderate 61 and severe 75.
Change in DASH increased with HAD category: none 36, mild 32, moderate 34, severe 49 but no statistically significant difference among groups was seen (p = 0.59).
Post-operative DASH tends to be worse if HAD is moderate or severe, 27 and 25, than none or mild, 19 and 17.
In conclusion, the difficulty of interpreting pre-operative anxiety or depression and outcome after trapeziectomy is establishing a causal relationship. Although the greater improvement is seen the more severe pre-operative anxiety or depression, absolute post-operative function tends to be worse. This study suggests that trapeziectomy offers equal functional improvement in the presence of POAC or without.
