Physiotherapy vs Corticosteroid Injection as a First Line Conservative Treatment for De Quervain's Tenosynovitis

A Review of De Quervain's Stenosing Tenovaginitis in the Context of Smartphone Use.

Background: De Quervain tenosynovitis (DQT) has been associated with repetitive movements of the radial first dorsal compartment. Since 2007, smartphones have become ingrained in society. Their functionality is primarily performed by dexterity of the user's thumb(s). The aim of this study was to review the current literature regarding the correlation between DQT and smartphone usage as a systematic review has not previously been presented. Methods: A literature review was conducted electronically using the EMBASE, PubMed, Cochrane and MEDLINE search libraries during May of 2019. Studies eligible for inclusion were English-language studies assessing the link between mobile phone use and DQT. Included studies were required to report on focused outcomes. Only original data studies were included. Case studies, those with data sets collected prior to 2007, foreign language research were excluded. Results: A positive Finkelstein's result within the cohorts was found in a mean of 51.54% of participants. Odds ratios (OR) of 1.5 to 2.3 were found with increasing frequency of text messages and DQT. Females were found to have a higher frequency of text messages daily. Internet browsing and gaming on mobile phones were associated with an OR of 2.21 and 2.61 respectively. DQT associated pain correlated to a mild disruption in daily tasks. On a visual analogue scale, this pain was represented as a 4 out of 10. Conclusions: In conclusion, there appears to be a linear association between frequency of text messages and incidence of DQT. Additionally, there is an association between DQT pain and a mild disruption to daily activities other than mobile phone use.

Incidence of De Quervain’s Tenosynovitis in Computer Operators

Background: De Quervain’s tenosynovitis is an inflammatory disease in which the pain is felt over the radial border of the wrist especially in the thumb with the ulnar deviation of the wrist. The objective of the study was to find out the incidence of De Quervain’s tenosynovitis in regular computer operators. Materials and Methods: Each participating person among the 147 regular computer operators was examined for the Finkelstein’s Test in order to diagnose the De Quervain’s tenosynovitis. Along with this a wrist pain questionnaire was asked to be filled in order to check the prevalence of wrist pain in regular computer operators. Results: Among 147 regular computer operators there were 74 (50.3%) males and 73 (49.7%) females with a mean age of 22.44 ± 1.81 years. Among 147 participating regular computer operators 99 (67.3%) showed the Finkelstein’s test positive whereas 48 (32.7%) showed the pain in Finkelstein’s test as being negative. Conclusion: It is concluded that the incidence of De Quervains Tenosynovitis among the regular computer operators on the basis of Finkelstien Test was quite high.

Association of Clinical and Radiological Features in Various Repetitive Stress Injuries.

Objectives To assess the clinical and radiological features of repetitive stress injuries (RSIs), specifically de Quervain’s (DQ) disease, tennis elbow (TE), and plantar fasciitis (PF).MethodsThis was an observational study conducted for eight months (March 2019 to September 2019) at the Orthopedic Department in collaboration with the Radiology Department. Clinically diagnosed RSI patients from both genders, aged between 30 and 50 years, were included in the study. Clinical features that were considered include pain, swelling, and site of injury. Radiological findings from ultrasound, X-ray, and magnetic resonance imaging (MRI) were identified in all participants of the study. Data were analyzed using SPSS Version 21 (IBM Corp., Armonk, NY, USA). Data were represented as frequency and percentages.ResultsThere were a total of 82 patients (40 males,42 females) with repetitive stress injury (RSI), with a mean age of 42.63±8.53 years. Of the 82 patients, 34 (41.4%) had DQ disease, 28 (34.1%) had TE, and 20 (24.4%) had PF. Pain and swelling were observed in all patients. In TE, the most affected site was the right lateral epicondyle process. The common radiological findings were hypoechoic fascia, increased fluid within the first extensor tendon compartment, cortical erosion, sclerosis in soft tissues, and calcification in soft tissues. Cozen’s test was positive in most patients. In DQ, the most affected sites were left and right radial styloid processes. The common radiological findings were hypoechoic fascia, increased fluid within the first extensor, cortical erosion, and periosteal reaction. Finkelstein’s test was also positive in most patients. In PT, the most affected site was the left heal plantar surface. The common radiological findings were hypoechoic fascia, increased thickness of fascia (>4.5 mm), increased fluid within the first extensor tendon compartment, cortical erosion, sclerosis in soft tissues, calcaneal spur, periosteal reaction, and calcification in soft tissues. Cozen’s and Finkelstein’s tests were also positive in most patients.ConclusionsHistory, physical examination, laboratory findings, and imaging modalities all are important tools for the differential diagnosis of RSI. Our study results showed that if some clinical findings fail to diagnose any RSI, then ultrasound, X-ray, and magnetic resonance imaging (MRI) are the best and useful options before treatment.

Conservative Management of de Quervain Stenosing Tenosynovitis: Review and Presentation of Treatment Algorithm.

Nonsurgical management of de Quervain disease relies mainly on the use of oral nonsteroidal antiinflammatory drug administration, splint therapy, and corticosteroid injections. Although the latter is most effective, with documented success rates of 61 to 83 percent, there exists no clear consensus pertaining to conservative treatment protocols conferring the best outcomes. This article reports on all present conservative treatment modalities in use for the management of de Quervain disease and highlights specific treatment- and patient-related factors associated with the best outcomes. A systematic search was performed using the PubMed database using appropriate search terms; two independent reviewers evaluated retrieved articles using strict inclusion and exclusion criteria. A total of 66 articles met the inclusion criteria for review, consisting of 22 articles reporting on outcomes following a single conservative treatment modality, eight articles reporting on combined treatment approaches, 13 articles directly comparing different conservative treatment regimens, and 23 case reports. A multimodal approach using splint therapy and corticosteroid injections appears to be more beneficial than either used in isolation. Although there exists some evidence showing that multipoint injection techniques and multiple injections before surgical referral may provide benefit over a single point injection technique and a single injection before surgery, corticosteroid use is not benign and should thus be performed with caution. Ultrasound was proven valuable in the visualization of an intercompartmental septum, and ultrasound-guided injections were shown to both be more accurate and confer better outcomes. Several prior and concurrent medical conditions may affect conservative treatment outcome. A Level I to II evidence-based treatment protocol is recommended for the optimal nonsurgical management of de Quervain disease.

Musculoskeletal Pain Symptoms and Injuries Among Endoscopists Who Perform ERCP.

The leaded protective gear worn, patient and endoscopist positioning, and longer average procedural time place endoscopists who perform endoscopic retrograde cholangiopancreatography (ERCP) at an increased risk of injuries as compared to other endoscopists. While multiple studies have investigated the prevalence of various pain symptoms and injuries among endoscopists, only one has been carried out in endoscopists who perform ERCP, and none have investigated potential predisposing risk factors. Our aim was thus to assess the prevalence of these pain symptoms, injuries, and potential risk factors. An anonymous electronic survey containing 23 questions was sent to 3276 gastroenterologists. Only providers that performed ERCPs were asked to respond. A total of 203 surveys were completed. Of the 203 respondents, 91% reported a musculoskeletal pain symptom. The most prevalent pain symptoms were neck pain (24%) and lower back pain (17%). In total, 48% of respondents reported a musculoskeletal injury. In total, 32% attributed these injuries to performing ERCPs. The most prevalent musculoskeletal injuries were De Quervain's tenosynovitis (16%) and cervical radiculopathy (12%). Only 25% of participants had received any education/training on ergonomics in endoscopy. The majority of endoscopists who perform ERCPs suffer from a musculoskeletal pain symptom, and almost half report a musculoskeletal injury. Further investigation regarding risk factors and preventative strategies is warranted. This information can then be incorporated into ergonomics education which only a small proportion of advanced endoscopists report having received any training in.

The Role of Platelet Rich Plasma in Comparison with Corticosteroids in the Treatment of De Quervain Tenosynovitis

Abstract Background: De Quervain's disease (DQVD) is the sten-osing tenosynovitis of tendons in the first extensor compart-ment. Its diagnosis is made clinically by Finkelstein test. Musculoskeletal ultrasound (MSUS) is used to confirm the diagnosis and for the follow-up after injection. One of the non-surgical strategies of treatment is platelet rich plasma (PRP) injection. Aim of Study: To evaluate the effects of PRP in the treatment of DQVD in comparison with corticosteroid (CS) injection. Subjects and Methods: 40 hands of 35 patients were included. 20 hands received single CS injection (group I) and the other 20 hands were injected with PRP (group II). Patients were evaluated using Visual analogue scale (VAS), Jebsen Hand Function Test (JHFT), the shortened disabilities of the arm, shoulder and hand questionnaire (Quick DASH), and the examination of the contents of the first dorsal compartment by MSUS at baseline, one and six months after the injection. Healthy side of patients were considered as control group (30 hands). Results: Overall, 31 females and 4 males were included with 20 hands in each group. The CS group had better pain relief, hand function tests and ultrasonograghic findings at 1 month, but at 6 months follow-up, the PRP group had statis-tically significant better pain relief, hand function tests and US findings than CS group. Conclusion: PRP injection is an effective treatment option for those patients with DQVD. The patients improved in pain intensity, disability and ultrasound findings. It is better than CS in the intermediate term by its ability to induce self-healing with no side effects.

The association between smartphone addiction and thumb/wrist pain: A cross-sectional study.

Many smartphone users experience pain in the thumb/wrist. This pain can be due to certain types of hand injuries as well as inflammation of the extensor pollicis brevis and the abductor pollicis longus tendon sheaths, known as De Quervain tenosynovitis. The objective of this study was to evaluate the association between smartphone addiction and wrist/thumb pain and to determine the severity of the pain, as well as to calculate the prevalence of De Quervain tenosynovitis among medical students at King Abdulaziz University (KAU) in Jeddah.A total of 387 medical students were enrolled. The smartphone addiction scale-short version (SAS-SV) was used to divide participants into the smartphone addict group and non-addict group. Both groups completed the self-administered patient-rated wrist and hand evaluation (PRWHE) questionnaire to evaluate wrist/hand pain. The Finkelstein test was administered to those who reported pain in the thumb/wrist.Two hundred fifty-seven (66.4%) participants were smartphone addicts; 74 (19.1%) had a positive Finkelstein test. There was a significant correlation between smartphone addiction and high PRWHE scores (P = .036).Our study found the prevalence of smartphones addiction among university students to be high (66%), furthermore a correlation between heavy smartphones usage and hand pain was found which indicates that heavy usage of these devices can cause subclinical effects on the human hand.

Injection Techniques for Common Chronic Pain Conditions of the Hand: A Comprehensive Review.

IntroductionThis compilation presents a comprehensive review of the literature on common chronic pain conditions of the hand. It briefly presents these common conditions with their biological background, diagnosis, and common management options. It then presents and compares the latest literature available for injection techniques to treat these diagnoses and compares the available evidence.MethodsA comprehensive literature review was performed in MEDLINE, PubMed, and Cochrane databases from 1996 to 2019 using the terms “hand pain”, “injection techniques”, “steroid injection”, “chronic pain”, “osteoarthritis”, “rheumatoid arthritis”, “carpal tunnel syndrome”, “De Quervain’s tenosynovitis”, “ganglion cyst”, “gout”, “Raynaud’s”, and “stenosing tenosynovitis”.ResultsHand pain is a common condition with 9.7% prevalence in men and 21.6% in women and can cause significant morbidity and disability. It also carries a significant cost to the individuals and the healthcare system, totaling in $4 billion dollars in 2003. Injection therapy is an alternative when conservative treatment fails. Osteoarthritis is the most common chronic hand pain syndrome and affects about 16% of the population. Its mechanism is largely mechanic, and as such, there is controversy if steroid injections are of benefit. Hyaluronic acid (HA) appears to provide substantial relief of pain and may increase functionality. More studies of HA are required to make a definite judgment on its efficacy. Similarly, steroid ganglion cyst injection may confer little benefit. Carpal tunnel syndrome is a compressive neuropathy, and only temporarily relieved with injection therapy. US-guidance provides significant improvement and, while severe cases may still require surgery, can provide a valuable bridge therapy to surgery when conservative treatment fails. Similar bridging treatments and increased efficacy under US-guidance are effective for stenosing tenosynovitis (“trigger finger”), though, interestingly, inflammatory background is associated with decreased effect in this case. When the etiology of the pain is inflammatory, such as in RA, corticosteroid (CS) injections provide significant pain relief and increased functionality. They do not, however, change the course of disease (unlike DMARDs). Another such example is De-Quervain tenosynovitis that sees good benefit from CS injections, and an increased efficacy with US-guidance, and similarly are CS injections for gout. For Raynaud’s phenomenon, Botox injections have encouraging results, but more studies are needed to determine safety and efficacy, as well as the possible difference in effect between primary and secondary Raynaud’s.ConclusionsChronic hand pain is a prevalent and serious condition and can cause significant morbidity and disability and interferes with independence and activities of daily living. Conservative treatment remains the first line of treatment; however, when first-line treatments fail, steroid injections can usually provide benefit. In some cases, HA or Botox may also be beneficial. US-guidance is increasing in hand injection and almost ubiquitously provides safer, more effective injections. Hand surgery remains the alternative for refractory pain.

Can Ultrasonography Be Useful in Planning Surgery for De Quervain Tenosynovitis?: A Prospective Study With Emphasis on Detection of the Superficial Radial Nerve and Dominant Pathologic Tendon.

We performed preoperative ultrasonography (US) to detect the anatomic course of the superficial radial nerve (SRN) and dominant pathologic tendon of the first extensor compartment in de Quervain tenosynovitis. We prospectively studied 27 patients (29 wrists) with de Quervain tenosynovitis who underwent surgical release of the first extensor compartment. Preoperatively, US was performed to evaluate the presence of the dominant pathologic tendon and the septum in the subcompartment, number of SRNs in the area of the surgical incision, and anatomic running course of the SRN. These variables were also checked intraoperatively. Cohen κ statistics were calculated to investigate agreement between US and surgical field findings. There were 7 men and 20 women (mean age, 47.8 years; range, 26-67 years). For the dominant pathologic tendon, there were 2 cases (6.9%) of an abductor pollicis longus, 11 cases (37.9%) of an extensor pollicis brevis, and 16 cases (55.2 %) of a nondominant tendon (κ = 0.94). For the subcompartment, there were 10 cases (34.5%) without a septum, 8 (27.6%) with an incomplete septum, and 11 (37.9%) with a complete septum (κ = 0.95). Most SRNs crossed over the first extensor compartment (κ = 0.78). Preoperative US can be useful in detecting the anatomic running course of the SRN and dominant pathologic tendon before surgery for de Quervain tenosynovitis. Classifying the anatomic course of the SRN could be essential to planning surgery, and it could be helpful to prevent injury of the SRN during surgery.

Methylprednisolone acetate injection with casting versus casting alone for the treatment of De-Quervain's Tenosynovitis: a randomized controlled trial.

To compare the success of treatment between thumb spica cast with "methylprednisolone acetate injection" versus thumb spica cast alone for the treatment of de Quervain's disease as functional outcomes, complications and patient compliance. A single blinded randomized controlled trial using a probability sampling technique was conducted from January 2014 to h February 2017at the Orthopaedic Unit II, King Edward Medical University / Mayo Hospital, Lahore. A total of 134 patients of both genders, between 30-60 years of age presented with wrist pain and diagnosed de Quervain's disease, were included in the study. Patients were randomly divided into two group by the computer allocation method. Patients in Group-A received thumb spica cast with methylprednisolone acetate and xylocaine injection while patients in Group-B were treated with thumb spica cast alone. The outcome variable was frequency of successful treatment which was noted and compared among the groups. Amongst the total 134 patients, the age of the patients ranged from 30 to 60 years with a mean of 37.16±5.15 years. Most of the patients were aged between 30 40 years (78.8%) followed by 41-50 years (21.2%). There were 38 (28.4%) male and 96 (71.6%) female patients in the study group with a male to female ratio of 1:2.5. In group-A mean VAS and Quick DASH score before treatment and after the treatment was statistically significant (p-value <0.001). In group-B mean VAS and Quick DASH score before and after the treatment was also significant (p-value <0.001) ( Table-2). The effectiveness of treatment was significantly higher in patients treated with thumb spica cast with methylprednisolone acetate injection as compared to thumb spica cast alone.

Anatomical variation in the first extensor compartment during treatment of De Quervain'S tenosynovitis

Background: De Quervain's disease is ste¬nosing tenosynovitis of the abductor pollicis longus and the extensor pollicis brevis within the first extensor retinaculum compartment of the wrist. The patient usually present with clinical symptoms like pain and a painful range of motions of the thumb which occur either due to increased friction force or due to increase in contain within the compartment during the gliding of the adductor pollicis longus (APL) and the extensor pollicis brevis (EPB) first extensor compartment. Following conservative trials of rest, moist heat, NSAID, and local steroid injections, surgical release of the first compartment are effective treatment modalities for De Quervain's disease, but these even leads to failure of treatment as there may be variation on the anatomy of first extensor compartment of wrist. We had done this study to find out anatomical variation in first extensor compartment during treatment of De Quervains tenosynovitis. Method: Anatomical Variations like presence or absence of septum between APL and EPB, number of tendon slip of APL and EPB in the first extensor compartment were studied in 16 patients of dequervains tenosynovitis who underwent open surgical release as the treatment. Result: 7/16 (43.75%) of patient has partial or complete Sub compartment in the fibro-osseous tunnel and 4/16 (25%) patient has extra Abductor Pollicis Longus (APL) tendon sheath in first extensor compartment. Conclusion: We found significant increase in variation of anatomy in first extensor compartment of De Quervains tenosynovitis patient which will be for the surgeon during the surgical release of first extensor compartment.

Trapezio-metacarpal arthritis: functional and radiographic results at an average 5-year follow-up using trapeziectomy associated to a modified Ceruso's suspensionplasty.

Background and aim:Trapezial-metacarpal arthritis (TMA) is a common and highly disabling pathology. Trapeziectomy and Ceruso’s suspensionplasty is described for moderate-severe stages. The aim of the present study was to assess functional and radiographic results at an average 5-year follow-up using a modified Ceruso’s technique where the Abductor Pollicis Longus (APL) is passed twice around the Flexor Carpi Radialis (FCR) and a suture mini-anchor in the base of the first metacarpal is used to further stabilize the thumb.Methods:85 consecutive modified Ceruso’s suspensionplasty were performed from 2012 and 2018. All patients were evaluated at an average 5.1-year follow-up (21-96 months). Subjective patient satisfaction rate, NRS, DASH score, abduction angle, Kapandji score and pinch strength using functional tests were assessed. The scapho-metacarpal distance was measured at follow-up radiographs.Results:90.6% of the patients were satisfied by the treatment. The NRS and the DASH score improved (from 8.5 pre-operatively to 1.53 and from 87.5 to 24.6 respectively - p<0.001). The Kapandji test was rated from 7 to 10 in 65.9% of the patients. The pinch strength was good in 75.3% of the patients at follow-up. The abduction angle of the thumb was 38.2° (20°-55°). The mean scapho-trapezial distance decreased of 2.45 mm (from 9.87 mm to 7.42 mm-p<0.05). Eight patients had persistent pain and thumb disfunction and 1 patient had De Quervain’s tenosynovitis.Conclusions:Suspensionplasty according to Ceruso is a relatively simple and reproducible technique for moderate-severe TMA. It improves pain and thumb function, giving good stability without significant shortening. (www.actabiomedica.it)

Prospective randomized comparison of ultrasonography-guided and blind corticosteroid injection for de Quervain's disease

Ultrasonography (US)-guided corticosteroid injection (CI) has been attempted to improve injection accuracy in de Quervain's disease (dQD), but its role in improving clinical outcomes and decreasing skin hypopigmentation or atrophy was not established well. We hypothesized that the US-guided CI is superior to blind CI in symptom improvement and development of skin hypopigmentation or atrophy. Forty-four patients (48 wrists) with dQD received ultrasonography-guided CI (24 wrists/22 patients, group A) or blind CI (24 wrists/22 patients, group B) between December 2016 and February 2018. The visual analogue scale for pain and the Patient-rated Wrist Evaluation (PRWE) were used for evaluation. Skin hypopigmentation or atrophy was evaluated using the modified Vancouver scar scale (mVSS) RESULTS: At 4weeks post-injection, pain and PRWE scores improved for 22wrists in group A and 21wrists in group B. At 3months post-injection, 10.0% (2/20) and 26.3% (5/19) of wrists in group A and B, respectively, had symptom recurrence after initial improvement. Improvement and aggravation rates were not significantly different between the groups. The incidence of skin hypopigmentation or atrophy was 69.6% (16/23 wrists) and 70.0% (14/20 wrists) in group A, and 59.1% (13/22 wrists) and 78.9% (15/19 wrists) in group B at 4weeks and 3months post-injection, respectively. The mean mVSS scores at the injection site in group A and B were 2.0 (0-4.0) and 1.8 (0-5.0) at 4weeks post-injection and 2.4 (0-7.0) and 2.9 (0-6.0) at 3 months post-injection, respectively. The incidence and severity of skin hypopigmentation or atrophy were not significantly different between the groups at both time points. Pain and clinical outcomes significantly improved after CI in dQD. Pain, clinical outcomes, and the incidence and severity of skin hypopigmentation or atrophy were not significantly different between ultrasonography-guided and blind CI. I, Therapeutic.

De Quervain’s disease (etiology, pathogenesis, diagnosis and treatment). Part II

De Quervains disease, despite its low prevalence, is accompanied by pain syndrome, dysfunction and a decrease in the strength of the hand. This leads to a significant decrease in the quality of life of the patient, disruption of his work and daily activities. Patients with de Quervains disease, make up a significant part of those who turn to orthopedists, surgeons, rehabilitation doctors. However, the individual features of the structure of the first back canal of each person, formed in the process of phylogenesis, the lack of data on the exact cause of the disease cause the complexity of diagnosis and treatment of the disease. In the first part of the lecture, devoted to de Quervains disease, modern literature data concerning the features of the anatomical structure of the first back canal, the etiology and pathogenesis of the disease are summarized. It also presents a description of the clinical picture of de Quervains disease, tests and instrumental methods of diagnosis, the algorithm of examination of the patient with this pathology.

Which Psychological Variables Are Associated With Pain and Function Before Surgery for de Quervain's Tenosynovitis? A Cross-sectional Study.

Depression, anxiety, and pain catastrophizing have been associated with worse pain and function in studies of patients with de Quervain's tenosynovitis. Illness perceptions are the patient's thoughts and feelings about their illness. More negative perceptions of the illness such as the illness having a long duration or serious consequences are associated with worse physical function in patients with hand osteoarthritis. It is currently unknown whether these psychological factors play a similar role in de Quervain's. We chose to study patients who have tried nonoperative management and have chosen surgical decompression due to persistent symptoms. Psychological factors may be associated with their ongoing pain and impaired function, so it is particularly important to investigate the role of psychosocial factors that may be targeted with non-invasive interventions. Which psychological variables are independently associated with baseline pain and function in patients undergoing surgical treatment for de Quervain's tenosynovitis, after controlling for clinical and demographic variables? This cross-sectional study included data from a longitudinally maintained database on 229 patients who had surgery for de Quervain's tenosynovitis between September 2017 and October 2018. All management options were discussed with patients, but many had already tried nonoperative management and chose surgery once referred to our institution. Our database included 958 patients with de Quervain's, with 69% (659) managed nonoperatively and 34% (326 of 958) who underwent surgical decompression. A total of 70% (229 of 958) completed all questionnaires and could be included in the study. With the numbers available, we found no differences between those included and those not analyzed in terms of age, gender, duration of symptoms, BMI, smoking status, and workload.Patients completed the Patient-Rated Wrist/Hand Evaluation (PRWHE), Patient Health Questionnaire for emotional distress, Pain Catastrophizing Scale (PCS), and the Brief Illness Perception Questionnaire. We investigated the relative contribution of patient demographics and individual psychosocial factors using a hierarchical multivariable linear regression model. In the first step we considered how demographic factors were associated with the baseline PRWHE score. In the second step we investigated the effect of pain catastrophizing and emotional distress on the baseline PRWHE score after accounting for confounding demographic factors. In the final step, the effect of illness perceptions on baseline PRWHE were considered after accounting for the confounding effects of demographic factors as well as pain catastrophizing and emotional distress. After controlling for confounding variables including workload and emotional distress, a more negative patient perception of the consequences of their condition and worse pain catastrophizing were associated with worse pain and function (consequences, β = 0.31; p < 0.01, pain catastrophizing β = 0.17; p = 0.03). A hierarchical multivariable regression analysis found that 11% of variance in baseline pain and function was explained by pain catastrophizing and emotional distress. Illness perceptions brought the total explained variance of the final model to 34%. More negative perceptions of the consequences of de Quervain's tenosynovitis and worse pain catastrophizing are associated with worse pain and reduced function at baseline in patients awaiting surgical decompression of de Quervain's tenosynovitis. In light of these findings, future studies might explore interventions to reduce pain catastrophizing and lower the perceived consequences of the condition. This may reduce the number of patients choosing surgical decompression or may also improve surgical outcomes. Further work should consider if these psychological factors are also associated with postoperative patient-reported outcomes. III, therapeutic study.

Wide Awake Local Anesthesia No Tourniquet: A Pilot Study for Carpal Tunnel Release in the Philippine Orthopedic Center.

Background: Wide Awake Local Anesthesia No Tourniquet (WALANT) uses a mixture of lidocaine and epinephrine for anesthesia and has found great success in hand surgery. At the Philippine Orthopedic Center (POC), we still use local anesthesia along with a tourniquet which gives the patient pain and discomfort at the tourniquet site. This study aims to determine perioperative and post-operative pain, intraoperative bleeding and immediate clinical outcomes of patients using WALANT for surgical anesthesia for carpal tunnel release. Methods: A case series of all patients who underwent carpal tunnel release under WALANT from April 2016 to September 2016 is presented. Those with concomitant trigger finger and de quervain disease which required release on the affected hand were also included. A tourniquet was on standby in case of uncontrollable bleeding. Intraoperative bleeding, pain NRS scores, and return to daily activity were noted. Results: Thirteen patients were included in the study; 3 were male, 10 were female. Mean age was 58 years, Mean surgical time was 15 minutes. Twelve were reported to have "some bleeding" and one was reported to have "bleeding but was still manageable". None of the surgeries were totally bloodless or had too much bleeding that necessitated a tourniquet. Pain NRS scores during injection of local anesthesia had a mean of 2. None of the patients felt pain during and immediately after the surgery. Average time return to daily activity was 6 days. No complications were noted. Conclusions: Patients included in the study who underwent carpal tunnel release under WALANT did not experience pain associated with a tourniquet. Visualization of the field was adequate enough for the surgeons to do the surgery without the need for a tourniquet and with no associated complications.
