    Does Use of a Night Extension Orthosis Improve Outcomes in Patients With Dupuytren Contracture Treated With Injectable Collagenase?
    (Elsevier, 2021-06-26) Bowers, Nathan Lorris; Merrell, Gregory Alan; Foster, Todd; Kaplan, F. Thomas D.; Orthopaedic Surgery, School of Medicine
    Purpose: Current prescribing information for the treatment of patients with Dupuytren contracture with injectable collagenase Clostridium histolyticum (CCH) recommends use of a night extension orthosis for 4 months after treatment. The present study examines whether this treatment improves the outcomes. Methods: Adult patients with Dupuytren contracture treated with CCH during the study period were eligible for inclusion. The patients were randomized to orthosis or no orthosis groups and were stratified based on the severity of contracture prior to randomization. The orthosis group was fitted postmanipulation with a hand-based custom orthosis that held the treated finger in maximal comfortable extension, and the patients were instructed to wear the orthosis at night for 3 months. The patients were assessed at 7-10 days, 30 days, and 90 days postmanipulation. Orthosis compliance was measured with a survey. The primary outcome measure was improvement in total active extension (TAE), defined as the sum of active metacarpophalangeal (MCP), proximal interphalangeal, and distal interphalangeal joint extension in the treated finger at 90 days after treatment. Secondary outcomes included total active flexion (TAF), Michigan Hand Questionnaire scores, patient satisfaction, and clinical success. Results: Twenty-six patients completed the study, 12 in the orthosis group and 14 in the no orthosis group. The majority of contractures (90%) were primarily through the MCP joint. The patients in both the groups demonstrated significant improvements in TAE at 90-day follow-up (orthosis P = .002, no orthosis P = .001) . The difference in improvement in the median TAE between the 2 groups was not significant (P = .40). There were no significant differences between groups for TAE, TAF, Michigan Hand Questionnaire scores, patient satisfaction, or clinical success at any of the time points assessed (P > .05). Conclusions: In patients with Dupuytren contracture with primarily MCP joint involvement, providing an orthosis after treatment with CCH may not offer a short-term benefit compared with CCH treatment alone in terms of TAE, TAF, or patient-reported outcome measures.

    Efficacy of a Single Image-Guided Corticosteroid Injection for Glenohumeral Arthritis
    (Elsevier, 2020) Metzger, Cameron M.; Farooq, Hassan; Merrell, Gregory A.; Kaplan, F. Thomas D.; Greenberg, Jeffrey A.; Crosby, Nicholas E.; Peck, Kathryn M.; Hoyer, Reed W.; Orthopaedic Surgery, School of Medicine
    Background There is limited data available on the efficacy of cortisone injection for glenohumeral osteoarthritis (GHOA). The amount and longevity of pain relief provided by a single cortisone injection is unclear. Additionally, it remains uncertain how the severity of radiographic GHOA and patient reported function and pain levels impact the efficacy of injection. Therefore, we sought to describe relief provided by a single, image guided glenohumeral injection for patients with GHOA. Additionally, we hypothesized that patients with more severe radiographic GHOA and poorer baseline shoulder function would require earlier secondary intervention. Methods Patients with symptomatic GHOA who elected to receive a corticosteroid injection for pain relief were prospectively enrolled. A phone interview was conducted to record baseline OSS and VAS scores prior to the injection, as well as at months 1, 2, 3, 4, 6, 9, and 12. Endpoints were designated when patients required a second injection, progressed to surgery, or reached month 12. Patients were grouped by their respective baseline OSS (mild, moderate/severe) and Samilson-Prieto radiographic classification (mild, moderate, severe) for analysis. Results Thirty shoulders (29 patients) were analyzed. 52% of patients were male. The average age of 66.1 years. No significant difference was seen in overall survival (defined as no additional intervention) between groups based on either OSS or Samilson-Prieto grades. Additionally, OSS and VAS scores at each follow-up were compared to baseline. For the entire cohort, a clinically significant difference was seen between baseline and months 1-4 for OSS and between baseline and months 1-4, 6,9, and 12 for VAS. Discussion This study aimed to determine the efficacy of corticosteroid injections for GHOA. There were no differences in the need for secondary interventions in this population based on severity of either the OSS or the Samilson-Prieto radiographic classification. However, patients with more severe shoulder dysfunction based on OSS did experience a statistically significant greater symptomatic relief compared with patients with milder dysfunction. Additionally, following a single injection, patients in this cohort experienced statistically and clinically relevant improvements in shoulder function and pain up to 4 months post-injection.

    Intrarater and Interrater Reliability of the Soong Classification for Distal Radius Volar Locking Plate Placement
    (Sage, 2019) Creighton, James J., III; Jensen, Courtney D.; Kaplan, F. Thomas D.; Orthopaedic Surgery, School of Medicine
    Background: The purpose of this study was to analyze the intrarater and interrater reliability of the Soong classification for volar locking plate placement on a randomly selected, consecutive series of radiographs. Our hypothesis was that the classification would be reliable. Methods: Six physicians of differing levels of training (orthopedic surgery intern to fellowship-trained upper extremity staff) were asked to review 40 radiographs in a random order on 2 separate occasions, 4 weeks apart. All observers graded each image (0, 1, or 2) based on the corresponding Soong grade. A weighted κ was used to determine the intrarater agreement. The interrater agreement was determined using an intraclass coefficient: Results: The intrarater reliability using a weighted κ ranged from 0.229 (95% confidence interval [CI]: 0.048-0.411) to 0.946 (95% CI: 0.840-1.051). The interrater intraclass coefficient for Randomization 1 was 0.944 (95% 0.912-0.967) and Randomization 2 was 0.877 (95% CI: 0.797-0.930). Conclusion: The Soong classification is a reliable tool, both interrater and intrarater, for assessing distal radius volar locking plate placement. The classification system remained reliable despite a randomly selected, consecutive series of images and physician observers of varying levels of training.
