The Evidence for Perioperative Anesthetic Techniques in the Prevention of New-Onset or Recurrent Complex Regional Pain Syndrome in Hand Surgery

Complex regional pain syndrome (CRPS) is a multifaceted condition characterized by chronic neuropathic pain, allodynia, and hyperalgesia. The incidence of CRPS postoperatively is alarmingly high, particularly following carpal tunnel surgeries, Dupuytren’s fasciectomy, and repairs of wrist and hand fractures, with recurrence rates soaring in individuals with a history of CRPS. Despite extensive research, the management of CRPS remains complicated, highlighting the urgent need for effective prevention strategies. This scoping review aimed to consolidate current evidence surrounding the efficacy of perioperative anesthetic techniques in preventing new-onset or recurrent CRPS, focusing on the application of various anesthetic interventions. Through a comprehensive literature search, eight articles were identified, discussing a spectrum of techniques, including wide awake local anesthesia no tourniquet (WALANT) and various regional blockade methods. This review revealed that the WALANT technique, with its simplicity and lower costs, exhibited promising results in preventing CRPS. Conversely, techniques involving intravenous regional and axillary plexus blocks showed variable efficacy, necessitating further investigation. The scarcity of high-quality evidence underscores the critical need for meticulously designed, large-scale randomized controlled trials to validate these findings and explore the potential of stellate ganglion block in the prevention of recurrent CRPS.

Plastic and Reconstructive Surgery in the Wake of the Eid al-Adha: A Single-Center, Five-Year Investigation.

(1) Background: The Festival of Sacrifice, commonly known as Eid al-Adha, has a profound religious and cultural impact on nations with a Muslim majority. This festival is celebrated every year in Muslim countries; however, it is a time in which patients present to the emergency department with serious injuries. In our study, we examined current injuries occurring during Eid al-Adha in one of the largest hospitals in Türkiye, providing the largest patient population to date. This included mapping tendon and maxillofacial injuries, a first in the literature. To the best of our knowledge, this is the largest case series of injuries sustained during Eid al-Adha. The significance of this study lies in its potential to significantly benefit patients and healthcare systems by providing reference data. (2) Methods: Patients admitted to Ankara City Hospital during Eid al-Adha between 2019 and 2023 were examined. The demographic characteristics, injury patterns, and injury sites of patients admitted on the four days of Eid al-Adha were collected and analyzed. Maxillofacial traumas during the festival were analyzed. Tendon injuries on the left hand, which is the most commonly injured body part in the literature, were mapped into a figure. To compare the change in the number of patients, a comparison was made with the number of patients in our hospital for four consecutive days 2 weeks before Eid. Statistical analysis was performed using IBM SPSS Statistics for Windows. (3) Results: A total of 610 patients, including 101 female and 509 male patients, were included in this study. A statistically significant increase (p < 0.001 for all years) in hospital admission due to injury was observed. Individuals between the ages of 30 and 40 years were the most frequently admitted patients (n = 182, 29.8%). Knife injuries were significantly more common in all patients (p < 0.001). When the total number of patients was evaluated in terms of injured areas where patients present to the emergency department, left-hand injuries were found to be significantly more common than injuries in other areas (p < 0.001 for all). The extensor pollicus longus tendon was the most commonly injured tendon among all extensor and flexor tendon injuries (n = 104). The most commonly injured tendon was the flexor tendon in zone 2 of the first finger (n = 45). This study showed that injuries to the extensor tendon in zone 1 of the fifth finger, the flexor tendon in zone 4 of the first finger, and the flexor tendon in zone 1 of the fifth finger were never seen. Twenty-five patients with maxillofacial injuries were admitted to the hospital. Orbital floor fractures were the most common type of maxillofacial injury. The anesthesia technique we preferred for all patients was local anesthesia (n = 267). Wide-awake local anesthesia no tourniquet (WALANT) was the second most preferred anesthetic technique. The number of patients who were selected in a random 4-day period for each year were compared with the number of patients who came during Eid al-Adha. The Mann-Whitney U tests revealed a significant increase in injuries on the first day of Eid al-Adha compared to non-festival days (p < 0.001). However, no significant differences were observed on the subsequent days or in the overall injury counts during the festival period (p = 0.841 for day 2, p = 0.151 for day 3, p = 0.310 for day 4). (4) Conclusions: According to this study, which is the largest known case series in the literature, the number of patients admitted to the hospital increased annually. In our study, we observed a significant increase in injuries only on the first day of Eid al-Adha compared to a randomly selected 4-day period of the same year. Left-hand extensor tendon injuries from a knife were the most common injuries in middle-aged men. The extensor pollicis longus tendon was the most commonly injured extensor tendon, with zones 3 and 4 being the most commonly affected. The flexor pollicis longus tendon was the most commonly injured flexor tendon in zone 2. During this period, patients may not only need hand surgery but also maxillofacial plastic surgery. We recommend, in addition to the indications I,n the literature that during Eid al-Adha, the WALANT technique should be widely adopted in patients where local anesthesia will be insufficient. We also recommend utilizing a diagram to manage the patient load during Eid al-Adha and prevent overburdening the healthcare system.

The value of local dexmedetomidine as an adjuvant to ultrasound-guided wide awake local anesthesia no tourniquet (WALANT) in flexor tendon repair surgeries: a randomized controlled trial

BackgroundThe Wide-Awake Local Anesthesia No Tourniquet (WALANT) technique allows intraoperative motor assessment of tendon repair integrity of the hand compared with general anesthesia or brachial plexus block. No studies have tested the effect of adding dexmedetomidine to lidocaine on the analgesic properties of the WALANT technique, which is the aim of our study.MethodsA total of 128 patients aged more than 18 years were scheduled for surgical flexor tendon injury repair using WALANT technique. Patients were divided into two equal groups. Ultrasound-guided subcutaneous injection of lidocaine 1% with dexmedetomidine (1 µg/kg), Group D, or without dexmedetomidine, Group C, was performed at four points: proximal to the wrist joint, the distal forearm, palm region, and proximal phalanges. The primary outcome was total morphine consumption throughout the first postoperative day. Secondary outcomes included number of patients requiring rescue analgesia, time to first analgesic request, and pain score.ResultsTotal morphine consumption was significantly (P < 0.001) lower in group D (2.66 ± 0.998) than in group C (3.66 ± 1.144) mg. Number of patients requiring rescue analgesia was significantly (P < 0.001) lower in group D (54.7% (35)) than group C (100.0% (64)). The time for first request for analgesia was significantly (P < 0.001) longer in group D (11.31 ± 6.944) than in group C (5.91 ± 4.839) h. Pain score was significantly higher in group C than D at three (P < 0.001), and six (P = 0.001) hours (P = 0.001) postoperatively.ConclusionDexmedetomidine significantly improves the analgesic quality of WALANT when added to lidocaine with less opioid consumption.Trial registration(ID: PACTR202203906027106; Date: 31/07/2023).

Infiltration Technique for the Fourth FDS Opponensplasty Under WALANT

Background: Wide-awake Local Anesthesia No Tourniquet (WALANT) is a surgical technique that relies on anesthetic and hemostatic agents to provide conditions suitable for hand surgery without sedation and a tourniquet. The opponensplasty using the fourth flexor digitorum superficialis tendon transfer with the pisiform pulley is one of the most used in severe carpal tunnel syndrome patient who is unable to perform thumb opposition due to thenar muscle atrophy with the benefit of small incision, less soft tissue dissection, easy to perform, good esthetic result and has minor morbidity. Key advantages of the pisiform pulley provide balancing abduction and flexion strength of the thumb. To date, there is no report using the WALANT technique for the fourth flexor digitorum superficialis opponensplasty with pisiform pulley. Materials and Method: Between January 2019 and January 2022, 18 patients (4 males and 14 females) with severe carpal tunnel syndrome with thenar muscle atrophy underwent fourth flexor digitorum superficialis opponensplasty as day surgery under the WALANT technique. Operative data, visual analog scale (VAS) pain scores, and complications were recorded. All patients underwent the procedure without any complications. Results: The average age of the patients was 58.4 (43 to 62) year-old. The average operative time was 38.4 (17 to 47) minutes. The average VAS score during the anesthetic injection was 6.43 (4 to -8). The average VAS pain score during the operation was 2.1 (1 to 3). The mean intraoperative blood loss was 3 (2.6 to 6.2) mL. Conclusions: The WALANT technique is safe and can be used as alternative anesthesia for the fourth flexor digitorum superficialis opponensplasty with pisiform pulley. This technique overcomes the problem of judging the appropriate amount of transfer tension by observing awake patients actively. Levels of Evidence: Therapeutic study, level IV

Dellon Triple Decompression under WALANT

The Wide-Awake Local Anesthesia No Tourniquet (WALANT) Approach to Dellon Triple decompression involves the use of local anesthetic with epinephrine and no tourniquet. This study shows that WALANT is a safe and effective procedure and can be performed in an outpatient setting for the decompression of the common peroneal nerve in the knee, tibial nerve in the ankle and deep peroneal nerve in the dorsum of the foot in diabetic patients with superimposed nerve compressions to diabetic neuropathy. WALANT technique demonstrated to be a safe procedure to surgically treat diabetic patients with superimposed compressive neuropathy to diabetic neuropathy in the lower limbs and had no complications.

Description of WALANT technique in open bone and ligament wrist surgery

The gold-standard for bone, ligament and joint surgery in the wrist is locoregional anesthesia in most countries. Wide-Awake Local Anesthesia No Tourniquet (WALANT) is commonly used for simple soft-tissue hand surgery procedures such as carpal tunnel or trigger finger release, and can now also be safely used in procedures such as proximal row carpectomy, scapholunate ligament repair or partial wrist fusion, to name but a few. This article describes the use of WALANT for complex surgery in the wrist. WALANT surgery offers many known benefits, such as enhanced patient safety and comfort, simplified perioperative process and avoidance of anesthesia-related risks, and also allows the surgeon to perform intraoperative testing of the repaired structures. Thus, the surgeon can tailor the rehabilitation program and shorten recovery time. We describe detailed guidelines for performing WALANT procedures safely and effectively, making it a favorable option for complex surgeries in the wrist.

The Use of Wide-Awake Local Anesthesia No Tourniquet (WALANT) Technique for Distal Fibula Hardware Removal

Ankle fracture is one of the most common fractures that are mainly treated with open reduction and internal fixation. Wide-awake local anesthesia no tourniquet (WALANT) technique has been widely used for hand and wrist surgeries, this method has been scarcely utilized in ankle surgery. To the best of our knowledge, only one study has evaluated the safety and efficacy of the WALANT technique in distal fibula hardware removal surgeries. This study aimed to investigate the result of using the WALANT technique in distal fibula hardware removal surgery. From April 2020 until March 2021 randomized clinical trial was performed on 60 patients between the ages of 18 and 60 years in our educational orthopedic center. In group A, an anesthesiologist administered spinal anesthesia and in group B the WALANT technique was used for anesthesia. The results of the current study showed that the visual analog scale in group B a day after the surgery was significantly lower, in comparison to group A. The outcome of our study demonstrated lesser blood loss in patients operated under the WALANT. This finding could be related to the vasoconstrictive properties of epinephrine used in the WALANT solution. Our findings suggest that the WALANT technique application in the proper setting and appropriate patient selection could lead to reduced postoperative pain, minimal bleeding, and shorter admission time. Other advantages include the simplicity and safety of the technique, it is being time and cost-effective. Level of Evidence: Diagnostic Level IV.

Comparative Study, Walant vs Axillary Block in Carpal Tunnel Surgery

Objectives: Wide awake local anesthesia no tourniquet (WALANT) is a local anesthetic technique that, in theory, reduces costs and surgical waiting periods. The purpose of this study was to compare axillary block (AXB) with WALANT in terms of pain scores, duration of hospital stay, and hand function in patients who underwent CTR surgery. Methods: Between January 2015 and February 2020, a retrospective analysis was conducted on the outcomes of 410 patients who underwent CTS surgery. The Walant technique was utilized on 210 patients, while the AXB technique was utilized on 200 patients. These two groups were compared regarding operative time, hospital stay, VAS score at specific intervals before and after surgery, and hand function recovery. Results: The mean operation time is 11 min (8-18) for WALANT group and 13 min (7-43) for AXB group. Average time of length of hospitalization is 4.2 hours (2-6) for WALANT and 14.2 hours (9-26) for AXB groups. The VAS scores of WALANT group is significiantly less than AXB group (p&lt;0.05). The percentages of being able to use their hands compared to their nonoperative hands were evaluated. These rates were higher in the WALANT group than in the AXB group (65-75% vs. 45-60%). Conclusion: Increased patient comfort was associated with the WALANT technique. It is superior to AXB in terms of patient satisfaction, postoperative long-term pain management, and hand function recovery. Assuming all safety recommendations are adhered to, WALANT is an alternative to tourniquets in CTS surgeries for obtaining a bloodless surgical field without the discomfort of tourniquet application.

Wide Awake Local Anesthesia No Tourniquet Surgery of Carpal Tunnel Syndrome: Patients' Experience and Recall Bias in a Day-Care Setting.

Background and Objective: Wide-Awake Local Anesthesia No Tourniquet (WALANT) is a technique of local anesthesia commonly used in the surgical treatment of a wide variety of conditions affecting the upper extremity, including Carpal Tunnel Syndrome (CTS). The recent retrospective studies investigated patient experiences in a wide variety of hand disorder-related cases. The aim of our study is to evaluate patient satisfaction regarding open surgical treatment for CTS using the WALANT technique. Material and Methods: we enrolled 82 patients with CTS without medical record of surgical treatment for CTS. For WALANT, a hand surgeon used a combination of 1:200,000 epinephrine, 1% lidocaine, and 1 mL 8.4% sodium bicarbonate solution without tourniquet application and sedating the patient. All patients were treated in a day-care setting. For assessment of patient experience, Lalonde's questionnaire was adapted. Participants completed survey twice: one month and six months after the surgical treatment was performed. Results: the median pre-operative pain score for all patients was 4 (range 0-8) after one month and 3 (range 1-8) after six months. The median intraoperative pain score for all patients was 1 (range 0-8) after one month and 1 (range 1-7) after six months. The median post-operative pain score for all patients was 3 (range 0-9) after one month and 1 (range 0-8) after six months. More than half (61% after one month and 73% after six months) of the patients responded by stating that their real experience of WALANT was better than their initial expectations. An absolute majority of patients (95% after one month and 90% after six months) would recommend WALANT treatment to their relatives. Conclusions: overall, patient satisfaction with treatment for CTS using WALANT is high. Furthermore, complications related to the performed treatment and persistent post-operative pain could be associated with more reliable patient recall of this healthcare intervention. A longer period of time between intervention and assessment of patient experience could possibly be a reason for recall bias.

Wide Awake Local Anesthesia No Tourniquet (WALANT) Versus Bier’s Block, in Internal Fixation of Unstable Metacarpal and Phalangeal Fractures of the Hand: A Comparative Study

Hand fractures are a common injury in emergency department, and the majority of these are stable injuries that can be treated conservatively with excellent functional results. When respective injuries are characterized as unstable, surgical reduction and stabilization is necessary. Generally, these operations are conducted under regional or general anesthesia to avoid pain and tourniquet for bloodless surgical fields. Wide Awake local anesthesia no tourniquet (WALANT) procedure is described as a local injection of anesthetic agent and epinephrine without tourniquet application, with scope to allow local anesthesia without other sedation and at the same time hemostasis. The purpose of the study is to compare the functional assessment of the hand function during a period of three months after surgical intervention for unstable metacarpal and phalangeal fractures under WALANT versus Biers block. Material &amp;Methods: Between May 2021 to October 2022, 43 patients with unstable metacarpal and phalangeal fractures underwent open reduction and internal fixation, 21 cases with Biers block(BB) anesthesia and rest with WALANT technique. Metacarpal fractures appeared in 29 cases and phalangeal fractures in 14 patients. Patients were operated within the first week from the injury. According to implants they employed locking plates, screws and Kirschner wires in two groups. Results: At three months postoperatively, Quick Dash Score is better in WALANT group while patients’ satisfaction does not differ between two groups. In WALANT group immediate postoperative median VA Score appeared 2/10, while in the Biers block group appeared 6/10. Patients which underwent WALANT technique were discharged on the same day after operation, while the patients with regional anesthesia the next postoperative day. Mean duration of analgesic use was sorter in WALANT group (2,3 days) than in BB group (5,7 days). Conclusion: Οbjective of surgical treatment of unstable hand fractures (metacarpal-phalangeal) is early mobilization and enhance hand functionality to avoid stiffness and tendon adhesions. Wide Awake local anesthesia no tourniquet technique is an alternative sedative procedure which immediately offers postoperative numerous advantages (low-cost technique, no complication from tourniquet, decrease sensation of intra or postoperative pain) compared with Bier’s block anesthesia. Based on our results we believe that WALANT technique offers many benefits in surgical treatment of hand fractures and is suggested as first choice anesthesiologist procedure.

Management of Scaphoid Pseudoarthrosis Surgery With Wide-Awake Local Anesthesia No Tourniquet (WALANT) Versus Axillary Block Anesthesia: Comparison of Patient Satisfaction

Objectives: We aimed to compare clinical and functional results of treatment of scaphoid pseudoarthrosis between patients undergoing wide-awake local anesthesia no tourniquet (WALANT) versus axillary block anesthesia. Methods: The patients diagnosed with scaphoid non-union who underwent pseudoarthoris surgery were divided into WALANT group ( n = 12) and axial block group ( n = 11). Visual analog scores (VAS) were measured by calling the patients via phone on postoperative days 1, 2, 3, and 7. The VASs were also measured on the 14th day during patient check-ups. At the end of 12 months, Michigan Hand Questionnaire was used to assess clinical recovery. Bone union rate and surgery time were also investigated. Radiological and clinical examinations were compared between the groups. Results: Eleven patients (91.7%) in the WALANT group and 10 patients (90.9%) in the axillary block group achieved bone union ( P = .94). Although there was no significant difference in preoperative VAS score between the groups, the WALANT group had significantly lower VAS score of the first 3 days postoperatively. However, there was no significant difference in VAS score between the groups on the seventh and 14th day postoperatively. There was no significant difference between the groups regarding Michigan score, time to surgery, time to union and operation time. Conclusion: The scaphoid pseudoarthrosis surgery can be done safely with WALANT technique which has significant lower VAS score on the first 3 days postoperatively.

WALANT Technique versus Local Anesthesia with a Tourniquet in Carpal Tunnel Syndrome.

Obtaining a blood-free surgical field is critical during carpal tunnel decompression (CTD) to identify anatomic structures and avoid iatrogenic injury. A tourniquet is often used to minimize bleeding and improve visualization. However, it may be associated with discomfort and intolerance when sedation is not employed. WALANT ("Wide awake local anesthesia no tourniquet") technique surgeries have become very popular and enable the patient to be involved in the procedure; in addition, the adrenaline avoids the use of the tourniquet and the discomfort it produces. We hypothesized that there is no difference in postoperative pain after CTD between local anesthetic with a tourniquet (LA-T) and WALANT technique. The objective of this paper is to report the results of CTD, comparing those performed with local anesthesia and those performed with the WALANT. In this prospective study, 60 CTS were operated in two different institutions. Patients in group 1 (30 patients) were operated under LA-T, while patients in group 2 (30patients) were operated on using lidocaine with epinephrine (WALANT). Statistical analysis was performed. Postoperative pain immediately after surgery, at 4 and 24 hours, and 15, and 30 days after surgery; and degree of satisfaction did not show a significant difference between the two groups. Moreover, surgical time was slightly shorter in the LA-T group, but the difference was not significant. In our study, CTD performed with LA-T, and WALANT technique resulted in similar results. In cases of experienced surgeons, LA-T may be enough to perform the procedure, avoiding epinephrine's low but complex complications. In less experienced surgeons who require more surgical time, the use of WALANT may increase the intraoperative comfort of the patient.

Effects of fixation of clavicle fracture using wide-awake local anesthesia no tourniquet (WALANT) technique on intra-operative bleeding volume, surgical duration, and post-operatively visual analog scale (VAS); A case series study

Clavicle fractures are common fractures with a rate of 2–5 percent among fractures. Mid-shaft fractures of the clavicle are more common than the other sites of the clavicle. Traditionally, surgical fixation of clavicle fractures has been performed under General Anesthesia (GA). The purpose of this study was to assess the effects of WALANT on intraoperative bleeding, pain control during and after surgery, postoperative complications and patients’ function. In the current study, 30 patients with clavicle fractures were surgically fixed using the WALANT technique. The obtained results showed that it could be an effective technique for pain control during the operation and also early postoperative period. Moreover, the WALANT technique could be considered safe in patients who are at risk for GA because of medical comorbidities, cervical spine injuries, or other factors that make intubation difficult.

Impact of WALANT Hand Surgery in a Secondary Care Hospital in Spain. Benefits to the Patient and the Health System

The aim of this study is to compare patient benefits and economic costs of hand surgeries using the wide-awake local anesthesia no tourniquet (WALANT) technique versus a conventional major outpatient suite and review outcomes and complications in a series of cases of patients operated on using the WALANT technique. A prospective cohort study was first conducted comparing 150 cases of ambulatory hand surgery (carpal tunnel syndrome and trigger finger) using the WALANT technique and not requiring an operating room setting with 150 cases of outpatient surgery performed in an operating room involving a preoperative evaluation and the use of sedation and tourniquet. Preoperative, intraoperative, and postoperative pain was monitored, and days requiring postoperative analgesia were recorded. The resources and costs were evaluated. and patient satisfaction was assessed using a specific survey.Subsequently, 580 patient medical records were retrospectively reviewed, including 419 carpal tunnel syndrome and 197 trigger finger interventions (616 WALANT surgeries). Intraoperative pain was equivalent for both groups, and postoperative pain was significantly lower in the WALANT group, with a reduced need for analgesics. Satisfaction was greater for the local anesthesia group. The use of personnel resources and hospital materials was reduced in the WALANT group, with a total estimated cost savings of 1.019 USD per patient.There were no complications related to the WALANT technique and the lidocaine and adrenaline combination. We found a complication rate of 5.58%, and, in line with the literature, most complications were minor, managed conservatively, and not related to the anesthetic technique. Procedures such as carpal tunnel and trigger finger surgeries can be safely performed using wide-awake surgery. Patient satisfaction is higher than with the conventional procedure performed in the operating room. Pain control is excellent, especially during the postoperative period. Hand surgery patients benefit from the WALANT technique in terms of comfort and timeliness because there is no need for preoperative tests or evaluations. In addition, it represents significant savings in hospital resources. In our case series, complications were in line with those previously reported with other anesthetic techniques.

Optimization of Carpal Tunnel Syndrome Using WALANT Method.

As surgical management of carpal tunnel release (CTR) becomes ever more common, extensive research has emerged to optimize the contextualization of this procedure. In particular, CTR under the wide-awake, local-anesthesia, no-tourniquet (WALANT) technique has emerged as a cost-effective, safe, and straightforward option for the millions who undergo this procedure worldwide. CTR under WALANT is associated with considerable cost savings and workflow efficiencies; it can be safely and effectively executed in an outpatient clinic under field sterility with less use of resources and production of waste, and it has consistently demonstrated standard or better post-operative pain control and satisfaction among patients. In this review of the literature, we describe the current findings on CTR using the WALANT technique.

Pediatric Wide-Awake Local Anesthesia No-Tourniquet Hand Surgery: A Practical Approach

Pediatric wide-awake local anesthesia no-tourniquet technique (WALANT) hand surgery is feasible for the treatment of the spectrum of pediatric hand surgeries, which can include traumatic injuries and congenital hand differences. The key component for success is identifying the appropriate patient for this technique, with the typical patient frequently being >10 years of age. The discussion with the patient and adequate preparation for maximum efficiency become key for patient and surgeon comfort. Here we describe a practical approach for successfully performing this valuable technique for the pediatric population.

Comparison of the WALANT and the PFNB techniques in the surgical treatment of unimalleolar fractures: a prospective study.

The popliteal fossa nerve block (PFNB) technique is one of the most popular anesthesia method in the foot and ankle surgery. The wide awake local anesthesia no tourniquet (WALANT) technique is an local anesthetic method and it has been gaining popularity in orthopedic surgery in recent years. Our aim is to compare the efficacy of the WALANT and the PFNB techniques in pain management. This prospective study included 40 patients with lateral malleolar and medial malleolar fractures. The first group was anesthetized using the WALANT technique; in the second group, PFNB was performed. All patients were evaluated for intrasurgical bleeding amounts, mean arterial pressure, surgery time and VAS scores for presurgical pain, pain during the local anesthetic injection sequence, mean intrasurgical pain, mean postsurgical pain. A total of 40 patients in both groups were successfully operated on with the WALANT and the PFNB techniques. When the two groups were compared, statistically significant differences were observed for mean intrasurgical VAS (p = 0.033), mean postsurgical VAS (p = 0.038) and intrasurgical bleeding (p = 0.006). No significant difference was found in pain scores during anesthetic injection (p = 0.529), mean arterial pressure (p = 0.583) and surgery time (p = 0.277). The PFNB technique is more successful in pain management in the treatment of the unimalleolar fractures. Intrasurgical bleeding amounts were less detected in the WALANT tech- nique. The both techniques are a reliable and suitable anesthetic method in the surgical treatment of uni- malleolar fractures.

Office-Based Intraosseous Infiltrations of PRGF in Knee Osteoarthritis: Description of Technique

Knee osteoarthritis is a low-degree inflammatory condition that involves the whole synovial joint tissues as an organ. Recently, a biological approach using plasma rich in growth factors (PRGF) to tackle not only the synovial joint with intraarticular injections of PRGF, but also the subchondral bone with intraosseous infiltrations has been implemented with promising results. However, this procedure requires sedation, which limits the implementation of the procedure to operating room. We propose a modified and less cumbersome PRGF intraosseous infiltration approach for moderate and severe knee osteoarthritis, conducting the procedure in the ambulatory setting assisted with WALANT (wide-awake local anesthesia no tourniquet) technique. The proposed technique with a minimally invasive local anesthesia involves subcutaneous infiltration of lidocaine and epinephrine in a solution without sedation, and using ultrasound guidance, thereby streamlining the original procedure. This procedure is both a cost-effective and safe approach that may contribute to the widespread use of intraosseous infiltrations.

Comparison of infraclavicular brachial plexus block versus wide-awake local anesthesia no-tourniquet technique in the management of radial shortening osteotomy.

Objectives The aim of this study was to evaluate the feasibility of the wide-awake local anesthesia no-tourniquet (WALANT) technique in radial shortening osteotomy and to compare it with the infraclavicular brachial plexus block (IBPB).Patients and methods Between January 2020 and January 2021, a total of 26 patients (16 males, 10 females, mean age: 40±4.9 years; range, 29 to 45 years) with Kienbock’s disease who underwent radial shortening osteotomy were retrospectively analyzed. The patients were divided into two groups according to the type of anesthesia as WALANT (Group 1, n=11) and IBPB (Group 2, n=15) anesthesia. Visual Analog Scale (VAS) during surgery, time from anesthesia to surgical incision, surgical time, overall patient satisfaction regarding the anesthesia was assessed. The Quick Disabilities of the Arm, Shoulder and Hand (Q-DASH) and handgrip strengths were compared at the final follow-up and short-term outcomes were analyzed.Results Age (p=0.896), sex (p=1.000), and dominant side involvement (p=1.000) were similar between the groups. Waiting time to start surgery in both groups was similar (27 vs. 25 min; p=0.053). Intraoperative VAS-pain scores and the satisfaction from the anesthesia type of both groups were also similar (p=0.546 and p=0.500).Conclusion The WALANT may be another anesthesia technique for radial shortening osteotomy with favorable outcomes. This technique adequately allows the surgeon to perform osteotomy and obtain a stable reduction without undue risk of tourniquet pain and palsy.

Application of wide-awake local anesthesia no tourniquet technique in the treatment of acute Achilles tendon rupture

To explore the value of wide-awake local anesthesia no tourniquet (WALANT) technique in the treatment of acute Achilles tendon rupture. In a prospective randomized controlled trial, 48 patients with acute Achilles tendon rupture who met the criteria between March 2020 and October 2020 were randomly divided into two groups according to 1∶1 distribution, with 24 cases in each group. The study group used WALANT technique and the control group used epidural anesthesia with tourniquet for channel-assisted minimally invasive repair (CAMIR). There was no significant difference between the two groups in gender, age, injured side, cause of injury, distance from broken end of Achilles tendon to calcaneal tubercle, and time from injury to hospitalization ( P>0.05). The operating room use time (from patients entering the operating room to leaving the operating room), intraoperative blood loss, hospital stay, and the highest pain score [using Numerical Rating Scale (NRS)] during operation and at 1 day after operation were recorded and compared between the two groups. The tourniquet adverse reactions in the control group were recorded. The functional recovery was evaluated by the scoring method of American Orthopedic Foot and Ankle Society (AOFAS) at 12 months after operation. The operation was successfully completed in both groups. The operating room use time and hospital stay in the study group were significantly less than those in the control group ( P<0.05), but the difference in the intraoperative blood loss between the two groups was not significant ( t=0.429, P=0.670). There was no significant difference in the highest NRS score during operation between the two groups ( t=1.671, P=0.101); the highest NRS score in the study group at 1 day after operation was significantly lower than that in the control group ( t=-6.384, P<0.001). In the control group, 13 patients had different degrees of tourniquet adverse reactions, including tourniquet regional pain, local swelling, blisters, thigh numbness, and discomfort. The patients in both groups were followed up 12-18 months, with an average of 13.9 months. The motor function of all patients returned to normal at 12 months after operation. The difference in AOFAS scores between the two groups was not significant ( t=0.345, P=0.731). There was no complication such as sural nerve injury, local infection, and secondary rupture in both groups. The application of WALANT combined with CAMIR technique in the treatment of acute Achilles tendon rupture has good anesthetic and effectiveness, avoids the adverse reactions of tourniquet, and reasonably saves social medical resources.
