Carpal Tunnel Syndrome in Autoimmune Rheumatic Diseases and Inflammatory Bowel Diseases: Retrospective Population Cohort Study

Risk of carpal tunnel syndrome among patients with osteoarthritis: a US population-based study

BACKGROUND

Carpal tunnel syndrome (CTS), an entrapment neuropathy caused by pressure of the median nerve, is a progressive condition that can lead to a decreased quality of life. Studies suggest an association between CTS and arthritis; however, previous studies examining osteoarthritis (OA) and CTS are limited in number, scope and study design. This study estimated the incidence and risk of CTS among patients with OA, both overall and by specific joints, in a large population-based cohort in the United States.

METHODS

Patients from the Optum claims database aged ≥ 45 years and diagnosed with OA between January 1, 2018, and December 31, 2022, were eligible for the OA cohort. The non-OA cohort included those without a diagnosis of OA at the index date and no history of OA for 12 months pre-index. Baseline characteristics were balanced using propensity score matching. The risk of CTS in the OA and non-OA cohort were evaluated using incidence rates and adjusted hazard ratios that were estimated using Cox regression.

RESULTS

After applying the inclusion/exclusion criteria, 3,610,240 of the 6,023,384 adults with a diagnosis of OA remained in the OA cohort. After propensity-score matching, each cohort included 1,033,439 individuals. The incidence rates for CTS per 1000 person-years were 7.35 (95% confidence interval [CI] 7.21-7.49) in the OA cohort and 1.44 (95% CI 1.38-1.50) in the non-OA cohort. The risk of developing CTS in patients with OA was ~ 4 times that of patients without (hazard ratio = 3.80; 95% CI 3.54-4.07). This increased risk was found across all OA joint types, with OA of the hand/wrist having the highest risk for CTS. Additionally, multiple OA joints presented a higher risk compared with a single affected joint.

CONCLUSIONS

OA increases the risk of CTS, but this is not limited to patients with hand/wrist OA, suggesting a systemic impact of OA on CTS. While the risk appears highest for patients with hand/wrist OA, patients with more distant affected joints like knee or hip also have an increased risk of CTS.

Effect of Acupotomy Combined with Electroacupuncture Therapy on Finger Mobility and Pain Relief in Patients with Carpal Tunnel Syndrome

Objective. To explore the effect of acupotomy in combination with electroacupuncture therapy on the finger mobility and pain relief in patients who had carpal tunnel syndrome (CTS). Methods. The clinical data of 60 CTS patients in our hospital from November 2020 to November 2021 received retrospective analysis. With 30 cases in each group, they were randomly divided into the treatment group and the control group. The control group underwent hot compress, oral medication, and local injection during hospitalization, while the treatment group received acupotomy and electroacupuncture therapy on top of the above treatments, and the clinical effects, finger mobility, and pain relief were compared between both groups. Results. The clinical indexes in the treatment group after treatment were remarkably better than those in the control group ( $P<0.05$ ), with the remarkably higher number of cured cases in the treatment group ( $P<0.05$ ). After treatment, the treatment group had remarkably higher mean total active motion (TAM) and score of the 36-item short form (SF-36) health survey and a remarkably lower mean score of visual analog scale (VAS) than those in the control group ( $P<0.001$ ). Conclusion. The quality of life and finger mobility of CTS sufferers can be improved with acupotomy in conjunction with electroacupuncture therapy. In-depth research will help build better procedures for these patients because this approach lessens the discomfort and shortens the symptom duration in CTS sufferers.
