The relationship between surgical site infection and preoperative corticosteroid injection for various procedures, findings on the long-term effectiveness of corticosteroid injection versus carpal tunnel release in the treatment of carpal tunnel syndrome, and other topics of interest are presented in the new JBJS Guest Editorial “What’s New in Hand and Wrist Surgery.” Here, we highlight the most impactful studies, as selected by author Deborah C. Bohn, MD.
Carpal Tunnel Syndrome
Researchers observed the long-term outcomes of corticosteroid injection vs. carpal tunnel release (CTR) in the treatment of carpal tunnel syndrome in patients originally enrolled in a randomized clinical trial (RCT). Ninety percent of the original cohort was available at a mean follow-up of 6.3 years. The incidence of therapeutic failure, defined as the need for any new treatment on the involved wrist, was greater in the injection group (41.6%) than in the CTR group (11.6%). Nonetheless, 58% of patients in the injection group did not need additional treatment in the 6 years following treatment1.
In a Level I RCT of 156 patients with Dupuytren disease, researchers found similar outcomes at 5 years for patients treated with collagenase Clostridium histolyticum (CCH) injection vs. those treated with percutaneous needle fasciotomy2. As Guest Editorial author Dr. Bohn notes, this study contributes to recent literature that has shown that CCH “provides little to no benefit over percutaneous needle fasciotomy in terms of recurrence or reintervention but is much more expensive.”
A recent study compared the outcomes of patients with zone-I flexor digitorum profundus (FDP) tendon laceration who were treated with either acute primary repair or non-repair (with or without tendon debridement). The nonrepair group (11 patients) had better objective outcomes and lower cost and fewer complications and therapy visits than the repair group (15 patients), and the groups had similar patient-reported outcomes3. Dr. Bohn notes that, “at the very least, this suggests that non-repair of an isolated FDP injury is not inferior to acute repair, which may help in counseling patients with delayed presentation.”
There is substantial empirical support for the use of corticosteroid injections in trigger finger, carpal tunnel syndrome, and thumb carpometacarpal joint (CMCJ) arthritis. However, recent literature on the relationship between surgical site infection (SSI) and corticosteroid injection for these conditions leads Dr. Bohn to conclude that “strong consideration should be given to avoiding ipsilateral hand surgery within 90 days after corticosteroid injection.” In one study, corticosteroid injection to the surgical site within 90 days prior to CMCJ arthroplasty was associated with a higher rate of SSI and wound complication4. In another investigation, preoperative corticosteroid injection (mean, 55 days) was associated with a higher infection rate after CTR5. Other studies found that corticosteroid injection within 30 days prior to trigger finger release was associated with an elevated risk of deep infection necessitating surgical debridement and that, within 90 days prior to trigger finger release, it increased the risk of SSI of any type6,7.
Pediatric patients with 100% displaced distal radial fractures who were treated with closed reduction and casting were found to have significantly worse angulation at final follow-up and higher emergency-department costs compared with a historical cohort who had been treated with in situ casting. Additionally, of the 50 patients in the reduction group, 36 (72%) had unacceptable alignment at some point in their follow-up8.
