Abstract

Abstract Background The treatment of patients with osteoarthritis of the first carpometacarpal joint (CMC-I) aims at pain reduction to improve hand function and quality of life. The CMC-I denervation procedure is relatively new and seems appealing, as it is minimally invasive and has few or no disadvantages. To date, however, little research has been done on the results of a CMC-I denervation. The aim of this study was to investigate whether denervation provides pain reduction in patients with early CMC-I osteoarthritis. Methods A literature search was done using PubMed. Studies were excluded if access to full text was not available, if the articles were written in other languages than Dutch or English, and if preoperative testing, follow-up testing, or reporting were incomplete. Studies were included if patients were older than 18 years, had primary CMC-I osteoarthritis with no other wrist pathology, and had received conservative treatment without sustained benefit. The Critical Appraisal Tools of the Joanna Briggs Institute were used for critical appraisal.Clinical data was gathered retrospectively from the medical records to identify patients who underwent CMC-I denervation in The Hand Clinic, Amsterdam. The data of 20 patients were analyzed. Pre- and postoperative visual analog scale (VAS) scores on pain, patient satisfaction, and complications were evaluated. Patients older than 18 years with primary CMC-I osteoarthritis stage I and II and no other wrist pathology, in whom conservative treatment failed were included in the study. Patients with CMC-I osteoarthritis stage III and IV were excluded. Results All 17 search results were screened for full text access, after which 6 case series, 4 systematic reviews, 1 cohort study, 1 comment, and 1 scoping review was included. All but one study showed pain reduction after surgery. In half of the studies, this difference was statistically significant. The average patient satisfaction in these studies was 84.1% and the complication rate was 13.4%.A total of 20 patients were included between 2019 and 2022, with a mean preoperative VAS for pain at rest of 48.2 ± 29.9. After surgery, this decreased to 35.8 ± 34.1. This difference was not statistically significant. The mean VAS for pain during use before denervation was 79 ± 18.4 and this decreased to 49.8 ± 34.2 postoperatively. This difference did appear to be statistically significant. The average patient satisfaction was 60%, and the complication rate was 10%. Conclusion This study provides a literature overview and a pilot study on pain reduction, patient satisfaction, and complications after denervation of the CMC-I joint in patients with early osteoarthritis. Our retrospective case series roughly mirrored the average results found in the literature. There was a statistically significant decrease in pain during use postoperatively. There was no statistically significant difference in pain at rest before and after surgery. The complications were mild and the complication rate was low; however, the average patient satisfaction rate was lower as compared to that reported in the literature.
