Wide Awake Trigger Finger Release Surgery: Prospective Comparison of Lidocaine, Marcaine, and Exparel.

Background: Local anesthetics are routinely used in hand surgery for procedures such as trigger finger releases (TFRs). However, little is known as to the difference in efficacy and patient experience with various local anesthetics. We prospectively evaluated the efficacy of Lidocaine (L), Marcaine (M), and Exparel (E) to elucidate differences in pain scores and opioid consumption between these groups. Methods: All consecutive TFR performed over a 6-month period in 2014 at our institution were divided to receive Lidocaine, Marcaine, or Marcaine with postoperative Exparel. Pain levels, daily opioid consumption, and adverse reactions were recorded and analyzed for postoperative day (POD) 0-3. Results: A total of 154 patients were enrolled (L:53, M:50, E:51). The Lidocaine group reported the highest pain levels for POD 0-1. Marcaine pain levels were similar to Exparel on POD 0 but higher on POD 1. Opioid consumption on POD 0-1 was significantly different with E:27%, M:58% and L:59% as was the number of pills consumed (E:0.70, M: 1.08 and L:1.62). In addition, 50% of Exparel patients required no pain medications and experienced significantly less adverse reactions (E:4%, M:10%, L:13%). By POD 2-3, there were no statistical differences between the 3 groups. Conclusions: Patients treated with Marcaine attain better pain control than Lidocaine on POD 0-1but only patients who received Exparel maintained the lowest pain levels through POD 0-3 while using little-to-no opioid medications and with less adverse reactions than Lidocaine or Marcaine alone.

Use of High-Speed X ray and Video to Analyze Distal Radius Fracture Pathomechanics

The purpose of this study is to investigate the failure sequence of the distal radius during a simulated fall onto an outstretched hand using cadaver forearms and high-speed X ray and video systems. This apparatus records the beginning and propagation of bony failure, ultimately resulting in distal radius or forearm fracture. The effects of 3 different wrist guard designs are investigated using this system. Serving as a proof-of-concept analysis, this study supports this imaging technique to be used in larger studies of orthopedic trauma and protective devices and specifically for distal radius fractures.

Patient Satisfaction in the Preoperative Period: Preparing for Hand Surgery:

Background: The potential impact of the number and type of preoperative encounters on satisfaction rates prior to elective surgical procedures is unclear, specifically scheduling and medical clearance encounters. Methods: Questionnaires investigating satisfaction with the preoperative process were collected for 200 patients presenting for elective hand surgery. The number of telephone, surgeon, and medical clearance encounters were recorded, and satisfaction was determined for each type based on a 4-category Likert scale. All patients 18 years or older were included, while only patients providing incomplete questionnaires were excluded. Outcome data were assessed for associations between different encounter totals or types and satisfaction rates. Results: Among 200 patients, 197 completed the questionnaire and were included. Overall satisfaction with the preoperative process was 92.9%, with only 3% of patients dissatisfied. There was a significant association between satisfaction and the number of telephone and total encounters. Satisfaction fell below 90% after 4 or more telephone calls (66.6%, P = 0.005) and 5 or more total encounters (80%, P = 0.008). When considered individually, there was no significant association between satisfaction and the number of surgeon (P = 0.267) or medical office encounters (P = 0.087), or a patient’s perceived health status (P = 0.14). Conclusions: Greater than 3 telephone or 4 total encounters significantly decreases patient satisfaction, while surgeon and medical office visits are not associated with satisfaction rates when considered individually. This suggests the number, not the type, of preoperative encounters impact satisfaction and highlight the importance of efficient communication between patients and providers.

Prospective Evaluation of Opioid Consumption Following Cubital Tunnel Decompression Surgery

Background: Managing postoperative pain is important for patients and surgeons. However, there is concern over opioid dependency. Cubital tunnel decompression is among the most common upper extremity surgeries. Our study aimed to analyze opioid use after cubital tunnel decompression to guide postoperative opioid prescribing. Methods: We prospectively collected opioid consumption for 16 consecutive months (February 2016 to June 2017) for cubital tunnel decompression patients. Data on demographics, insurance type, surgery performed, functional questionnaires (Quick Disabilities of the Arm, Shoulder and Hand [QuickDASH]), and electrodiagnostics (electromyography) were collected. Opioid consumption was reported at first postoperative visits. Results: One hundred patients consumed a mean of 50 morphine equivalent units (MEUs) (range, 0-300), or 7 oxycodone 5-mg pills, postoperatively. Cubital tunnel release (CuTR) patients consumed fewer than ulnar nerve transposition (UNT) patients (40.4 vs 62.5 MEUs or 5.4 vs 8.3 pills, P = .08). Patients undergoing submuscular UNT consumed more than CuTR (115.0 vs 40.4 MEUs or 15.3 vs 5.4 pills, p = 0.003) and more than subcutaneous UNT patients (37.8 MEU or 5.0 pills, p = 0.03). Medicare patients consumed less than privately insured (42.7 vs 54.1 MEUs, 5.7 vs 7.2 pills, P = .02) and less than workers’ compensation patients (76.8 MEU or 10.2 pills, P = .04). Older patients consumed fewer than younger patients (P = .03). Postoperative QuickDASH score was positively related to opioid intake (P = .009). Conclusions: Patients consumed 7 oxycodone 5-mg pills after cubital tunnel decompression. Younger, privately insured, and workers’ compensation patients, and those with worse functional scores and those undergoing UNT (specifically the submuscular technique) consumed more opioids.
