Applying the WALANT technique to surgical treatment of distal radius fractures

New Frontiers in Wide-Awake Surgery

LEARNING OBJECTIVES

After studying this article, the participant should be able to: 1. Explain the most important benefits of wide-awake surgery to patients. 2. Tumesce large parts of the body with minimal pain local anesthesia injection technique to eliminate the need for sedation for many operations. 3. Apply tourniquet-free surgery to upper and lower limb operations to avoid the sedation required to tolerate tourniquet pain. 4. Move many procedures out of the main operating room to minor procedure rooms with no increase in infection rates to decrease unnecessary cost and solid waste in surgery.

SUMMARY

Three disruptive innovations are changing the landscape of surgery: (1) minimally painful injection of large-volume, low-concentration tumescent local anesthesia eliminates the need for sedation for many procedures over the entire body; (2) epinephrine vasoconstriction in tumescent local anesthesia is a good alternative to the tourniquet and proximal nerve blocks in extremity surgery (sedation for tourniquet pain is no longer required for many procedures); and (3) evidence-based sterility and the elimination of sedation enable many larger procedures to move out of the main operating room into minor procedure rooms with no increase in infection rates. This continuing medical education article explores some of the new frontiers in which these changes affect surgery all over the body.

Considering occupational performance during recovery of distal radius fracture: A scoping review

INTRODUCTION

Distal radius fracture (DRF) is one of the most common upper extremity fractures treated by hand therapists and can lead to chronic physical impairment and reduced occupational performance. This scoping review aimed to reveal what is currently known about occupational performance following DRF and to explore if and how occupational performance is defined and considered in the research.

METHODS

This review was guided by the PRISMA-Scoping review and the Joanna Briggs Institute (JBI) guidelines. Relevant databases were searched, and studies that addressed occupation performance in adult participants following DRF were included. The findings were summarised according to the components of occupational performance (person, occupation, and environment), and quality was measured using the Mixed Methods Appraisal Tool.

RESULTS

Forty-three articles met the eligibility criteria for inclusion. All of the studies discussed at least two components of occupational performance, while 25 recognised all three. The consideration of occupational performance was dominated by biomechanical issues associated with the person component (i.e. range of motion, strength). There was some acknowledgement of the psychosocial aspects of the person and, to a lesser extent, the environment, as well as the impact of both on return to occupational performance.

CONCLUSION

Despite occupational performance being at the core of occupational therapy theory, its consideration within the context of research on DRF appears to be focussed on the person component of occupational performance and on biomechanical issues. Further research is recommended to determine how much this reflects current clinical practice and if a more comprehensive consideration of occupational performance will improve rates of recovery following DRF.

CONSUMER AND COMMUNITY INVOLVEMENT

As part of the protocol development for this review, consumers and stakeholders were consulted. They provided feedback on clarity and importance of the research questions.

PLAIN LANGUAGE SUMMARY

A distal radius fracture happens when you break the bone on the thumb side of your wrist. This type of injury often occurs when you fall and land on an outstretched hand. It is one of the more common injuries that hand therapists see in their practice. For some people, recovering from this fracture can take a long time and come with a lot of pain, difficulty moving, and emotional stress. These problems can make it hard to do everyday things like driving, cooking, or getting dressed. It can also affect both paid and unpaid work as well as leisure and social activities, making life more difficult for everyone involved. The findings from this review suggest that the current research usually focuses on how the body physically heals from this type of injury, but it does not pay as much attention to the emotional and social impact on healing. Also, it does not always discuss the activities that are important to the person, or the environment where they live, work, and socialise. This may show a gap in the research regarding our full comprehension of recovery from distal radius fractures. Taking a broader view and approach to recovery, considering a person's emotions, social life, environment, and daily activities, could help people recover fully and get back to their previous life routines and roles after this type of injury.

Complications and side effects of Wide-Awake Local Anaesthesia No Tourniquet (WALANT) in upper limb surgery: a systematic review and meta-analysis

PURPOSE

Wide-Awake Local Anaesthesia No Tourniquet (WALANT), a groundbreaking anaesthetic technique resurging in practice, warrants a comprehensive safety analysis for informed adoption. Our study aimed to identify complications/side effects of WALANT upper limb procedures through a systematic review and meta-analysis.

METHODS

This PROSPERO-registered study was performed with strict adherence to PRISMA guidelines. Embase, OVIDMedline, Cochrane, Web of Science, and Scopus databases were searched until February 2023. Inclusion criteria involved English articles, reporting complications/side effects in primary WALANT upper limb surgeries. Outcomes included all complications and side effects, data on the anaesthetic mixture, publication year/location, study type, and procedures performed. The meta-analysis employed the Freeman-Tukey Double Arcsine Transformation, computed I2 statistics, and utilized common or random effects models for pooled analysis.

RESULTS

2002 studies were identified; 79 studies met the inclusion criteria representing 15,595 WALANT patients. A total of 301 patients had complications, and the meta-analysis using a random effects model provided a complication rate of 1.7% (95% CI: 0.93-2.7%). The most reported complications were superficial infection (41%, n = 123/300), other/specified (12%, n = 37/300), and recurrent disease (6.7%, n = 20/300). A decade-by-decade analysis revealed no statistically significant difference in complication rates spanning the last three decades (p = 0.42). Adding sodium bicarbonate to the anaesthetic solution significantly reduced postoperative complications (p = 0.025).

CONCLUSION

WALANT has a low overall complication rate of 1.7%, with no significant temporal variation and a significant reduction in complications when sodium bicarbonate is added to the anaesthetic solution. Our findings support the safety of WALANT in upper limb procedures.

Fixation of Distal Radius Fractures Under Wide-Awake Local Anesthesia: A Systematic Review

BACKGROUND

The purpose of this systematic review was to analyze the available literature on fixation of distal radius fractures (DRFs) under wide-awake local anesthesia no-tourniquet (WALANT), and to examine postoperative pain scores and functional outcomes, operative data including operative time and blood loss, and the frequency of adverse events.

METHODS

Embase, MEDLINE, Web of Science, and SCOPUS were searched from inception until May 2022 for relevant studies. Studies were screened in duplicate, and data on pain scores, functional outcomes, and adverse events were recorded. Due to methodological and statistical heterogeneity, the results are presented in a descriptive fashion.

RESULTS

Ten studies were included comprising 456 patients with closed, unilateral DRFs, of whom 226 underwent fixation under WALANT. These patients had a mean age of 52.8 ± 8.3 years, were 48% female, and had a mean follow-up time of 11.6 months (range: 6-24). Operative time for WALANT patients averaged 60.4 ± 6.5 minutes, with mean postoperative pain scores of 1.4 ± 0.6 on a 10-point scale. Studies that compared WALANT to general anesthesia found shorter hospital stays with most WALANT patients being sent home the same day, decreased postoperative pain scores, and decreased costs to the healthcare system. No adverse events were reported for WALANT patients.

CONCLUSIONS

A growing body of literature reports that for closed, unilateral DRF, surgical fixation under WALANT is a safe and effective option. It allows patients to have surgery sooner, with improved pain scores and good functional outcomes, with a very low incidence of adverse events.

Wide-awake local anesthesia and no tourniquet (WALANT) in upper limb fractures

Wide-awake local anesthesia and no tourniquet (WALANT), first used for hand surgery, has been sparingly described for use in fracture fixation of the upper limb. We present our experience using this technique. 26 patients with upper limb fractures (3 distal radius, 6 radial shaft, 11 ulnar shaft, and 6 olecranon fractures) were operated on using WALANT by three orthopedic surgeons. We used 35-40ml of 2% Lignocaine with 1:80000 Adrenaline(7mg/kg) diluted with normal saline. Numeric Pain Rating (NPR) scoring was done during injection and per-operatively, and the Likert scale was used for the surgeon's satisfaction. The average NPR score was reported as 0.65 (1-3) during injection and 0.15 (0-2) preoperatively. All three surgeons reported excellent satisfaction in all the cases operated on. No complication occurred due to anesthesia. WALANT is a much simpler option and can be safely used in place of general anesthesia or regional blocks for fixation of fractures of the upper limb, with added advantages of no need for a tourniquet and better intraoperative assessment of fracture fixation.

Distal radius fracture fixation using WALANT versus general and regional anesthesia: A systematic review and meta-analysis

BACKGROUND

WALANT (wide-awake local anaesthetic no tourniquet) has become a popular technique in upper limb surgery including distal radius fracture fixation. The purpose of this systematic review and meta-analysis is to assess the effectiveness of the WALANT technique in distal radius fracture fixation, and to compare it to both general and regional anaesthesia.

METHODS

Pubmed, Embase, and Scopus databases were searched on 26/06/21 according to the PRISMA guidelines with the following search terms: radius, WALANT, "local anesthetic", wide-awake surgery. All studies comparing WALANT with other forms of anaesthesia for distal radius fracture fixation were included.

RESULTS

110 articles were identified, six studies (410 patients) were included, 164 of these patients were in the WALANT group. Two patients (1.2%) in the WALANT group and seven (6.5%) in the regional anaesthesia group required conversion to general anaesthesia. There was no statistically significant difference in post-operative complications, intra-operative VAS pain scores, operative times, functional or radiological outcomes. A statistically significant 8.6 mls increase in pooled mean blood loss in the WALANT group was noted (p = 0.02) although the clinical significance of this is doubtful.

CONCLUSION

The WALANT technique for distal radius fracture fixation is non-inferior to regional and general anaesthesia. It is a safe and effective technique that surgeons may consider utilising, especially for patients not suitable for general anaesthetic or in centres in which there is a lack of access to specialist anaesthetic equipment and care.

Less Fluctuation in Hemodynamics of the Wide-Awake Local Anesthesia No Tourniquet Technique Than General Anesthesia in Distal Radius Plating Surgery: A Prospective Case-Control Study

This prospective case-control study aimed to compare the intraoperative hemodynamic changes between the wide-awake local anesthesia no tourniquet (WALANT) technique and general anesthesia (GA) in patients undergoing distal radius plating surgery. Forty adults with distal radius fractures underwent plating surgery via the WALANT technique (20 patients) or GA (20 patients). Mean arterial pressure (MAP) and heart rate were recorded. Intraoperative pain intensity was measured using the visual analog scale (VAS) for pain in the WALANT group. The measures of hemodynamics and VAS were recorded at seven-time points perioperatively. The VAS score decreased significantly compared with the preoperative status in the WALANT group for most of the intraoperative period except during injections of local anesthetics and fracture reduction. The intraoperative MAP in the WALANT group showed no significant change during the perioperative period. In addition, the WALANT group showed fewer perioperative MAP fluctuations than the GA group (p < 0.05). The reduction and plating quality were similar between the two groups. WALANT provided a feasible technique with less fluctuation in hemodynamic status. With gentle manipulation of the fracture reduction, distal radius plating surgery using the WALANT technique is a well-tolerated surgical procedure and shows similar reduction and plating quality to GA.

WALANT technique versus locoregional anesthesia in the surgical management of metacarpal and phalangeal fractures: Lessons from the Covid-19 crisis

Wide Awake Local Anesthesia No Tourniquet (WALANT) is an anesthetic method which uses a local injection of anesthetic and epinephrine, avoiding use of a tourniquet. During the COVID-19 pandemic, human and logistic resources had to be reorganized, and WALANT ensured resilience in our department to maintain access to surgical care. The objective of the present study was to compare hand function recovery 3 months after surgery for unstable metacarpal or phalangeal fracture under regional anesthesia versus WALANT. From November 2020 to May 2021, 36 patients presenting a metacarpal or phalangeal fracture requiring surgical treatment were included in a single-center study in a university hospital center. Nineteen patients underwent surgery under locoregional anesthesia with tourniquet, and 17 under WALANT. The main endpoint was functional recovery at 3 months on QuickDASH score. Need for complementary anesthesia, surgery duration, analgesic consumption, reintervention rate, and patient satisfaction were also assessed. There was no significant difference between groups in functional recovery at 3 months or on the secondary endpoints. In the COVID-19 context, WALANT proved to be a safe and effective method in hand fracture surgery, ensuring access to surgical care. It should be included in surgical training to optimize day-to-day surgical care and face future crises.
