Background: Corticosteroid injection is the mainstay of nonoperative treatment for trigger finger (stenosing tenosynovitis), but despite substantial experience with this treatment, there is minimal available evidence as to the optimal corticosteroid dosing. The purpose of this study is to compare the efficacy of 3 different injection dosages of triamcinolone acetonide for the treatment of trigger finger. Methods: Patients diagnosed with a trigger finger were prospectively enrolled and treated with an initial triamcinolone acetonide (Kenalog) injection of 5 mg, 10 mg, or 20 mg. Patients were followed longitudinally over a 6-month period. Patients were assessed for duration of clinical response, clinical failure, Visual Analog Scale (VAS) pain scores, and Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) scores. Results: A total of 146 patients (163 trigger fingers) were enrolled over a 26-month period. At 6-month follow-up, injections were still effective (without recurrence, secondary injection, or surgery) in 52% of the 5-mg group, 62% of the 10-mg group, and 79% of the 20-mg group. Visual Analog Scale at final follow-up improved by 2.2 in the 5-mg group, 2.7 in the 10-mg group, and 4.5 in the 20-mg group. The QuickDASH scores at final follow-up improved by 11.8 in the 5-mg group, 21.5 in the 10-mg group, and 28.9 in the 20-mg group. Conclusions: Minimal evidence exists to guide the optimal dosing of steroid injection in trigger digits. When compared with 5-mg and 10-mg doses, a 20-mg dose was found to have a significantly higher rate of clinical effectiveness at 6-month follow-up. The VAS and QuickDASH scores were not significantly different between the 3 groups.
Background The use of tourniquets and their role in extremity-based microsurgery has not been thoroughly investigated. The purpose of this study was to investigate tourniquet use and its associated outcomes and complications. Methods Approval from the Institutional Review Boards was granted at each site. A retrospective chart review was completed for patients who had undergone extremity-based microsurgery with the use of a tourniquet between 01/01/2018 and 02/01/2021 at two large academic institutions. Demographic characteristics, initial reasons for surgery, complications, and outcomes were recorded. Patients were separated into groups based on tourniquet-use during three operative segments: (1) flap elevation, (2) vessel harvest and (3) microvascular anastomosis. An internal comparison of complication rate was performed between cases for which a tourniquet was used for one operative segment to all cases in which it was not used for the same operative segment. Univariate and multivariate statistical analyses were performed to identify statistically significant results. Results A total of 99 patients (106 surgeries) were included in this study across sites. The mean age was 41.2 years and 67.7% of the patients were male. The most common reason for microsurgical reconstruction was a traumatic event (50.5%). The need for an additional unplanned surgery was the most common surgical complication (16%). 70% of procedures used a tourniquet for flap elevation. When these cases were compared to those that did not use a tourniquet for flap elevation, there was no difference in complication rates. 61% of procedures used a tourniquet for vessel harvest and 32% for anastomosis. Similarly, additional analyses identified no difference in complication rates when compared to procedures for which a tourniquet was not used for the intervention. Conclusions Based on these results, the authors encourage the use of tourniquets for extremity-based microsurgery to enable bloodless dissection without the concern of increased complication rates.
Background: The purpose of this study was to compare the demographic differences of the most common peripheral nerve compressions in the upper extremity—carpal tunnel syndrome (CTS), ulnar nerve compression (UNC) at the elbow, combined CTS and UNC, radial tunnel syndrome (RTS), and posterior interosseous nerve syndrome (PINS)—as a means to better understand the etiologies of each. Methods: A retrospective chart review was performed of all patients over the age of 18 years seen at our institution in the 2018 calendar year. International Classification of Diseases, Tenth Revision codes were used to identify patients with diagnoses of upper extremity peripheral nerve compressions. Demographic details and relevant comorbidities were recorded for each patient and compared with controls, who were seen the same calendar year with no neuropathies. χ2 analyses, independent-samples t tests, and multivariate logistic regressions were performed ( P < .05). Results: A total of 7448 patients were identified. Those with CTS were mainly women, former smokers, and diabetic (all P < .001) and with a greater average body mass index (BMI) ( P = .006) than controls. Patients with UNC were more often men and younger when compared with controls (both P < .001). A history of smoking, diabetes, and average BMI were similar between patients with UNC and controls (all P > .05). Those patients with combined CTS/UNC were mainly men, former smokers, and diabetic (all P < .001) when compared with controls. Patients with RTS/PINS were also mostly men ( P = .007), diabetic ( P = .042), and were more often current smokers ( P < .001). Conclusions: The demographics of patients with various compressive neuropathies were not homogeneous, suggesting different etiologies.
Dorsal wrist pain during extension or weight bearing is a common symptom, the etiology of which often remains unclear. Clinical MRI often fails to reveal causative pathology in part because it is performed in the neutral position. We built an apparatus to guide motion and used a flexible coil to capture signal in a range of positions that better match the conditions during which pain is reported. Results in nine asymptomatic volunteers show excellent tissue structure delineation, strong measurement agreement among readers, and increases in dorsal capsule thickness and radiocapitate, radiolunate, capitolunate and extensor tendon angulation during weight bearing.
