Does the Number of Preoperative Corticosteroid Injections Affect Clinical and Radiographic Outcomes of Trapeziectomy and Suspensionplasty?

This study aimed to determine whether an increasing number of preoperative corticosteroid injections is associated with greater radiographic subsidence of the thumb metacarpal at long-term follow-up after abductor pollicis longus suspensionplasty, secondary to steroid-induced pathologic weakening of capsuloligamentous restraints surrounding the thumb carpometacarpophalangeal joint and greater extension of the lunate, but neither affect patient-reported outcomes nor revision rates.A retrospective chart review was performed of patients who underwent primary trapeziectomy and abductor pollicis longus suspensionplasty by a single surgeon over a 10-year period. The number of preoperative corticosteroid injections in the trapeziometacarpal joint was documented, and patients were separated into 4 subgroups: 0, 1, 2, or 3 or more injections. Preoperative and final radiographs were evaluated for a change in the distance between the base of the thumb metacarpal and the distal pole of the scaphoid as a measure of thumb metacarpal subsidence and radiolunate angle as a measure of nondissociative carpal instability, which has been reported as a complication after basal joint arthroplasty. Additionally, the final patient-reported outcomes (Quick Disabilities of the Arm, Shoulder, and Hand and Patient-Rated Wrist Evaluation) and revision rates were also assessed.Of a total of 60 patients with an average age of 64 years that were included in the study, 16 (26.7%) received 0, 19 (31.7%) received 1, 12 (20%) received 2, and 13 (21.7%) received 3+ preoperative injections. The median postoperative follow-up was 92 months. The mean distance between the base of the thumb metacarpal and the distal pole of the scaphoid decreased by 2 mm, and the mean radiolunate angle increased by 4° across the entire cohort. When comparing subgroups, no differences were observed in either parameter or the final Patient-Rated Wrist Evaluation and Quick Disabilities of the Arm, Shoulder, and Hand scores.This study demonstrates no apparent detrimental effect of an increased number of preoperative corticosteroid injections on radiographic thumb metacarpal subsidence, increase in extension of radiolunate angle (nondissociative carpal instability), patient-reported outcomes, or revision rates at an average of almost 8 years after trapeziectomy and abductor pollicis longus suspensionplasty.Therapeutic IV.Copyright © 2022 American Society for Surgery of the Hand.
