Complications within the first year after trapeziectomy with a Weilby sling for treatment of thumb-based osteoarthritis may increase the chance of poor clinical outcomes, according to results presented at the Virtual EFORT Congress.
Lisa Hoogendam, BSc, collected Michigan Hand Outcomes Questionnaire scores preoperatively and at 12 months postoperatively among 535 patients with primary thumb-based OA who underwent trapeziectomy with a Weilby sling. Researchers used the International Consortium for Health Outcomes Measurement (ICHOM) guidelines to score complications. Hoogendam noted the grade of complication depended on the treatment that the complication required.
“So, grade 1 is only analgesics or hand therapy; grade 2 is steroid injections or antibiotics; and grade 3 is additional surgical intervention or complex regional pain syndrome,” Hoogendam said. “We applied a multivariate linear regression to assess the association between complication grade and pain 12 months postoperatively.”
Hoogendam noted almost one-third of patients reported any complication according to ICHOM guidelines, with 8% of patients reporting grade 3 complications. Patients with no complications reported the highest Michigan Hand Outcome Questionnaire scores, according to Hoogendam.
“As the grade of the complication increases, patients have worse outcomes 12 months postoperatively,” Hoogendam said.
