Relationships between the global symptom score and electrophysiological findings after surgical release for carpal tunnel syndrome: Indications and outcomes.

Regarding surgical indications for carpal tunnel syndrome (CTS), the hypothesis that the recovery processes of subjective symptoms differ among pain, sensory, and motor symptoms and correlate with recovery in objective nerve conduction studies was examined in the present study. The global symptom score (GSS) is a method used to assess clinical outcomes and covers subjective symptoms, including pain (pain and nocturnal awakening), sensory (numbness and paresthesia), and motor (weakness/clumsiness) symptoms. The relationships between long-term changes in GSS and recovery in nerve conduction studies were investigated. Forty patients (40 hands) were included (mean age 65years; 80% female; 68% with moderate CTS: sensory nerve conduction velocity < 45m/s and motor nerve distal latency > 4.5ms). Pain and nocturnal awakening rapidly subsided within 1month after surgery and did not recur in the long term (median 5.6years). Paresthesia significantly decreased 3months after surgery and in the long term thereafter. Weakness/clumsiness significantly decreased at 1year. Sensory nerve distal latency, conduction velocity, and amplitude significantly improved 3months and 1year after surgery, and correlated with nocturnal awakening in the short term (3months) in moderate CTS cases. The patient satisfaction rate was 91%. Rapid recovery was observed in pain and nocturnal awakening, of which nocturnal awakening correlated with the recovery of sensory nerve conduction velocity. Patients with pain symptoms due to moderate CTS may benefit from surgical release.

Diagnostic Accuracy of Integrating Ultrasound and Shear Wave Elastography in Assessing Carpal Tunnel Syndrome Severity: a Prospective Observational Study.

Carpal tunnel syndrome (CTS) is a common condition characterized by compression of the median nerve (MN) within the carpal tunnel. Accurate diagnosis and assessment of CTS severity are crucial for appropriate management decisions. This study aimed to investigate the combined diagnostic utility of B-mode ultrasound (US) and shear wave elastography (SWE) for assessing the severity of CTS in comparison to electrodiagnostic tests (EDT). This prospective observational study was conducted over 9-month periods at a tertiary care hospital. A total of 48 patients (36 females, 12 males; mean age 44 ± 10.9 years; age range 28-57 years) with clinically suspected CTS were enrolled. All patients underwent EDT, US, and SWE. Based on the EDT results, CTS cases were categorized into four groups: mild, moderate, severe, and negative. The cross-sectional area (CSA) and elasticity (E) of the MN were measured at the tunnel inlet (CSAu and Eu) and pronator quadratus region (CSAo and Eo). The differences (CSAu-CSAo and Eu-Eo) were calculated. The primary outcomes were the diagnostic performance of CSAu, CSAu-CSAo, Eu, and Eu-Eo in differentiating moderate/severe from mild/negative CTS compared to EDT findings. Secondary outcomes included a correlation of US/SWE parameters with EDT grades and between each other. ANOVA, correlation, regression, and receiver operating characteristic (ROC) curve analyses were performed. CSAu and CSAu-CSAo increased progressively with worsening CTS severity. E measurements were significantly higher in moderate-to-severe CTS compared to mild or negative cases. The combined metric of CSAu-CSAo at a 5 mm threshold exhibited enhanced performance, with a higher sensitivity (83.3%), specificity (100%), and area under the curve (AUC) (0.98), surpassing the results of CSAu when used independently. Similarly, the SWE measurements indicated that Eu-Eo at a 56.1kPa cutoff achieved an AUC of 0.95, with a sensitivity of 93.3% and specificity of 94.4%, outperforming the metrics for Eu when used alone, which had an AUC of 0.93, with identical sensitivity and specificity values (93.3% and 94.4%, respectively). The integration of ultrasound, shear wave elastography, and electrodiagnostic tests provides a comprehensive approach to evaluate anatomical and neurological changes and guide management decisions for CTS.

Opposition Transfer Using the Extensor Indicis Muscle and the Extensor Pollicis Brevis Tendon

PurposeThis study aimed to introduce a novel technique utilizing the extensor pollicis brevis and extensor indicis proprius tendons as power sources for thumb opposition reconstruction in cases of severe carpal tunnel syndrome (CTS) associated with thenar muscle atrophy. Further, the efficacy of this novel method and the traditional Camitz technique was compared. MethodsPatients with severe CTS and thumb opposition dysfunction who underwent surgery using the novel technique (n = 7, 9 surgeries) or the Camitz technique (n = 8, 8 surgeries) were included in the analysis. The pre- and postoperative palmar abduction angle, thumb–ring finger opposition (T–R) angle, and Kapandji score were assessed. The repeated measures ANOVA and the Mann–Whitney U test were used for statistical analysis. ResultsThe novel technique was associated with a significant postoperative improvement in palmar abduction angle, T–R angle, and Kapandji score. In particular, the T–R angle of patients who underwent surgery using this technique was superior to that of patients who underwent surgery using the Camitz technique. Therefore, the novel technique was highly effective in improving thumb pronation. ConclusionThe novel technique using the extensor pollicis brevis and extensor indicis proprius tendons is promising for thumb opposition reconstruction in severe CTS cases. Unlike the traditional Camitz technique, this approach promotes stable thumb opposition function without requiring a pulley, thereby yielding satisfactory outcomes. Nevertheless, further studies with a larger sample size should be conducted to validate these findings.

Carpal tunnel syndrome among Manitoba workers: Results from the Manitoba Occupational Disease Surveillance System.

Carpal tunnel syndrome (CTS) is associated with occupational high-force repetitive tasks and vibration. This project examines the relationship between CTS and work to: (1) identify jobs and industries with increased CTS risk; (2) explore whether there is a sex difference in the risk of CTS after controlling for occupation; and (3) determine whether any observed relationships persist after excluding Workers Compensation Board (WCB) accepted time-loss CTS claims. We linked 95.5% of time-loss WCB claims from 2006 to 2019 to provincial administrative health data. The cohort included 143,001 unique person-occupation combinations. CTS cases were defined as at least two medical claims for (ICD-9 354) within a 12-month period or a surgical claim for CTS from 2 years before the WCB claim to 3 years after. WCB accepted CTS time-loss claims not identified by the medical claims were also included. A total of 4302 individuals (3.0%) met the CTS definition. Analysis revealed that the hazard ratios (HRs) of CTS vary considerably with occupation. Sex-based differences in CTS risks were observed, both in low- and high-risk occupations. In many occupations with increased HR, the HR remained elevated after excluding accepted time-loss WCB cases. The risk of developing CTS varied with occupation. Job titles with ergonomic risk factors had higher risks than those with lower exposures. This finding remained after eliminating time-loss compensated WCB cases, suggesting that all cases of CTS in high risk jobs are not identified in WCB statistics. Female workers in some job titles had excess CTS cases compared to male workers within the same job title.

Association of upper extremity anthropometry and subcutaneus adipose tissue with carpal tunnel syndrome

<p>Body mass index (BMI) is positively correlated with the frequency of carpal tunnel syndrome (CTS). However, there are different types of obesity, and the localization of adipose tissue differs between the genders. In this study, we purposed to investigate whether there was an association between the amount of local adipose tissue thickness and anthropometry in upper extremity with the presence and/or electrophysiological severity of CTS on both genders.</p>. <p>Our study included 150 patients who were diagnosed with CTS clinically and electrophysiologically and 165 healthy controls. The biceps and triceps skinfold thickness, the diameters of the wrist and metacarpal joints, and the upper arm circumferences over the belly of the biceps muscle were measured by using skinfold caliper and measuring cylinder. All data were analyzed by using the Statistics Open For All package (SofaStats) programme. To detect the role of anthropometric indexes, we used multivariable multinomial logistic regression models.&nbsp;</p>. <p>We revealed that BMI, biceps and triceps adipose tissue thicknesses were higher in females and also in patients with CTS. There was a positive correlation between electrophysiological grades of CTS and BMI with logistic regression analyzes. The mean Wrist circumference/Metacarpo&shy;ph&shy;arengeal Circumference ratio and biceps circumference were higher in moderate CTS groups. Metacarpofarengeal circumference was smaller in mild and moderate CTS cases compared to healthy ones.</p>. <p>We suggest that the differen&shy;ces between the anatomical bone structure and local adiposity between the genders may play an important role in the occurrence of CTS. Moreover, the structures of proximal muscle groups and distal metacarpal joints may contribute both to the development and severity of CTS.</p>.

Central Sensitization in Patients with Chronic Pain Secondary to Carpal Tunnel Syndrome and Determinants.

Central sensitization (CS) is commonly seen in chronic pain disorders, including neuropathic pain. However, there exist inconsistencies concerning the presence of CS in chronic pain secondary to carpal tunnel syndrome (CTS). CS and neuropathic pain manifestations in CTS remain not well established. Therefore, this study aims to investigate the CS and pain profiles in patients with CTS and to explore the potential determinants associated with CS. Patients with suspected CTS symptoms lasting 3 months or above and healthy controls were enrolled. History, physical examinations, and nerve conduction studies were employed to confirm the diagnosis and severity of median nerve dysfunction. The central sensitization inventory (CSI) was used to screen CS. Other outcomes included neuropathic pain, CTS-specific symptom severity and functions, emotion, and health-related quality of life. Between-group comparisons were conducted in terms of the CS presence. Logistic regression analysis was performed to identify determinants associated with CS. Over 60% of participants with CTS were found with clinical CS, significantly higher than that in the control group. More than 70% of the CTS participants were identified to have possible or very likely neuropathic pain components. In addition, one-fourth of CTS cases had depression or anxiety. Anxiety was associated with an increased risk of developing CS in CTS (adjusted OR=1.31, 95% CI 1.08-1.59), whereas higher self-perceived general health rating was negatively associated with the presence of CS (adjusted OR=0.92, 95% CI 0.88-0.97) in the multivariate adjusted regression model. CS is prevalent in patients with CTS. Predominant neuropathic pain characteristics were uncovered in CTS patients as well as comorbid psychological distress. Significant association was found between anxiety and CS presence. Self-perceived general health was inversely related to CS. Further research is warranted to explore the mechanisms of anxiety and central pain processing in painful entrapment neuropathy.

Neurostimulation in severe carpal tunnel release: A more precise technique for opponensplasty decision-making.

In this study, we aimed to investigate the relationship between intraoperative thenar muscle neurostimulation responses and postoperative thumb function recovery in patients with severe carpal tunnel syndrome (CTS). Between January 2019 and December 2021, a total of 21 severe CTS cases in 20 patients (7 males, 13 females; mean age: 56.3±19.3 years; range, 52 to 76 years) based on clinical and electrophysiological findings were retrospectively analyzed. The median nerve motor branch (MNMB) was stimulated intraoperatively with a nerve stimulator. The patients were divided into two groups according to contraction response on abductor pollicis brevis (APB) muscle: Group C (contractile, n=13) and Group NR (non-responsive, n=7) with and without muscular contraction. The Levine Functional Severity Scale (LFSS) was used to measure the functional status of CTS patients. The Manual Muscle Testing (MMT) was used to assess muscle strength. Clinical outcomes were compared between the groups at one year of follow-up. The mean total preoperative LFSS score was significantly higher in Group NR than in Group C (p=0.010). The mean postoperative MMT score was significantly higher in Group C than in Group NR (p<0.001). There was no positive result in pick-up, button fastening, and needle pinch tests in Group NR (p<0.001). However, there were significant improvements in postoperative LFSS scores in Group C (p<0.05), while the scores remained unchanged in Group NR (p>0.05). Direct stimulation of the median nerve motor branch and observation of contraction response on APB muscle can be used to predict clinical recovery and facilitates making the decision for opponensplasty in severe CTS.

Carpal Tunnel Syndrome Associated with Immune Checkpoint Inhibitors.

Immune checkpoint inhibitors (ICIs) have transformed the therapeutic approach to diverse malignancies, leading to substantial enhancements in patient prognosis. However, along with their benefits, ICIs also increase the incidence of immune-related adverse events (irAEs). In the present paper, we highlight four cases of carpal tunnel syndrome (CTS) as an uncommon manifestation of toxicity induced by ICIs. Although diagnosed with different malignancies, the patients were undergoing ICI therapy when they developed CTS-consistent side effects accompanied by severe neuropathy. Prompt treatment with corticosteroids, intravenous immunoglobulins, or methotrexate resulted in complete symptomatic relief for all patients. This article therefore emphasizes the importance of recognizing and managing rare adverse events associated with ICI use to ensure optimal patient care.

Persistent Pain as an Early Indicator for Operative Carpal Tunnel Revision after Primary Release: A Retrospective Analysis of Recurrent and Persistent Carpal Tunnel Syndrome.

Prolonged symptoms of carpal tunnel syndrome (CTS) after primary carpal tunnel release (CTR) can reduce the quality of life and lead to multiple referrals across specialties. The following study aimed to identify differences in symptoms, signs, and intraoperative findings between recurrent and persistent CTS cases to avoid undesired outcomes after primary CTR. A retrospective analysis was conducted on revision CTRs performed between 2005 and 2015 using literature-based definitions for recurrent (a relapse of symptoms occurs following a symptom-free period of ≥3 months) and persistent (symptoms persisting longer than three months after surgical release) CTS. The parameters assessed were symptoms, clinical signs, and intraoperative findings. Out of 53 cases, 85% (n = 45) were external referrals, whereby our own revision rate was 0.67% (n = 8/1199). Paresthesia and numbness were frequent in both groups; however, abnormal postoperative pain was reported more often in persistent cases (86%; n = 30/35) in comparison to recurrent cases (50%; n = 9/18; p = 0.009). Scarring around the median nerve was observed in almost all recurrent cases (94%; n = 17/18) and in 40% (n = 14/35) of persistent cases (p < 0.001). Incomplete division of the palmar ligament was the primary cause for revision in the persistent cohort (49%; n = 17/35). For patients experiencing symptoms for more than three months after CTR, primarily presenting as pain, it is advisable to consider referring the patient to a certified hand clinic for additional evaluation.

Carpal Tunnel Syndrome: Neuropathic Pain Associated or Not with a Nociplastic Condition.

Carpal tunnel syndrome (CTS) has been traditionally classified as primarily a neuropathic condition with or without pain. Precision medicine refers to an evidence-based method of grouping patients based on their susceptibility to biology, prognosis of a particular disease, or in their response to a specific treatment, and tailoring specific treatments accordingly. In 2021, the International Association for the Study of Pain (IASP) proposed a grading system for classifying patients into nociceptive, neuropathic, or nociplastic phenotypes. This position paper presents data supporting the possibility of subgrouping individuals with specific CTS related-pain into nociceptive, neuropathic, nociplastic or mixed-type phenotypes. Carpal tunnel syndrome is a neuropathic condition but can also be comorbid with a nociplastic pain condition. The presence of extra-median symptoms and the development of facilitated pain processing seem to be signs suggesting that specific CTS cases can be classified as the nociplastic pain phenotype. The clinical responses of therapeutic approaches for the management of CTS are inconclusive. Accordingly, the ability to identify the predominant pain phenotype in patients with CTS could likely be problematic for producing efficient treatment outcomes. In fact, the presence of a nociplastic or mixed-type pain phenotype would explain the lack of clinical effect of treatment interventions targeting the carpal tunnel area selectively. We propose a clinical decision tree by using the 2021 IASP classification criteria for identifying the predominant pain phenotype in people with CTS-related pain, albeit CTS being a priori a neuropathic pain condition. The identification of a nociplastic-associated condition requires a more nuanced multimodal treatment approach to achieve better treatment outcomes.

Recurrent carpal tunnel syndrome: Outcomes after neurolysis and synovial flap

ObjectivesIf symptoms recur after primary neurolysis of the median nerve, surgical revision is required. Soltani et al. (2013) demonstrated that surgical revision with vascularized flap coverage had a higher success rate (86%) than surgical revision without a flap (75%). The aim of this retrospective study was to present clinical outcomes in 36 cases of secondary open neurolysis of the median nerve, with synovial flap in case of recurrent carpal tunnel syndrome. MethodThirty-three patients (36 hands) who had undergone secondary neurolysis of the median nerve combined with synovial flap coverage between 2012 and 2019 were selected for this study. We included only recurrent carpal tunnel syndrome cases presenting with scarring of the transverse carpal ligament or epineural fibrosis of the median nerve and with a symptom-free period of at least 3 months. The results were ranked on a 4-point scale as excellent, good, null or poor, depending on progression at last follow-up. ResultsDescriptive analysis showed that 80% of patients had a positive outcome (excellent 33%, good 47%), 6% null outcome and 14% poor outcome. ConclusionThis is an interesting, relatively non-invasive surgical option, and should be part of the therapeutic armamentarium for recurrent carpal tunnel syndrome in case of adherence of the nerve to the transverse carpal ligament.

Feasibility study of juxta-articular-type volar distal radius plate (ARIX Wrist System) for surgically treating marginal distal radius fractures

PurposeWe evaluated the feasibility of a juxta-articular-type volar distal radius plate for the surgical treatment of marginal distal radius fractures. Materials and methodsTwenty marginal distal radius fractures, defined by the location of the fracture line within 10 mm of the joint line of the lunate fossa, were retrospectively reviewed between July 2020 and July 2022. The fractures were fixed using a juxta-articular-type volar plate (ARIX Wrist System). The characteristics of the implant and surgical technique, radiologic, and clinical outcomes, and related complications were evaluated. ResultsBony union was achieved in all patients within six months. Acceptable radiological alignment was achieved with no significant differences between the fractured and the normal sides. The clinical outcomes were favorable, with satisfactory functional outcomes. There was one case of post-traumatic arthritis and two cases of carpal tunnel syndrome. No implant-related complications including flexor tendon problems were observed. ConclusionThe juxta-articular distal radius plate of the Arix Wrist system is feasible for treating marginal distal radius fractures and achieves favorable clinical outcomes without implant-related complications in East Asian patients.

AĞIR KARPAL TÜNEL SENDROMU İÇİN RİSK FAKTÖRLERİNİN İNCELENMESİ - EV HANIMLIĞI BİR RİSK Mİ?

Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy. In this study, risk factors of severe CTS were examined. This study was conducted on 227 patients diagnosed with CTS in EMG laboratuary. The criteria of American Academy of Electrodiagnostic Medicine was used as the diagnosis for CTS. All patients were examined for bilateral median and ulnar motor and sensory peak latency, amplitude and conduction velocities. The patients were classified into 4 groups electrophysiologically; Normal, Light, Medium, Severe. Electrophysiological classification was compared with the identified risk factors. The mean age of the patients was 51.04±13.37 (min=18-max=83). Severe CTS cases in both hands were higher in housewives. Housewifery increased the risk of severe CTS in the right and left hand by 2.74 and 2.23 times, respectively. In addition, obesity increased the risk of severe CTS in the right and left hand by 5.10-4.40, presence of lateral epicondylitis was 2.73-4.19 and medial epicondylitis was 4.39-4.93, respectively. Hand dominancy was increased the risk of severe CTS by 6.88 times for the left hand and 1.15 times for the right hand. Otherwise in multivariate analyse of left hand results, obesity increase the risk of severe CTS by 3.34, left hand dominancy 7.83 times, chronic disease 2.62 times, and for the right hand being a housewife increases the risk by 2.14, obesity 4.68 times and medial epicondylitis 6.40 times. This study put forth that being a housewife, obesity, dominant hand, presence of lateral or medial epicondylitis are the risk factors of severe CTS.

Can Electrodiagnostic Tests be Omitted from Surgical Decision-making for Typical Carpal Tunnel Syndrome? – A Randomized Controlled Trial

ABSTRACT Background: Although carpal tunnel syndrome (CTS) is common and frequently seen in daily practice, diagnostic criteria remain the subject of debate. Some authors consider electrodiagnostic tests as essential, whereas others view them as an unnecessary luxury. Objective: The objective is to investigate whether electrodiagnostic tests are necessary for surgical decision-making for typical CTS. Materials and Methods: The study was planned as a randomized controlled trial. After determining normative values for the population of the geographic region, 101 consecutive cases of typical CTS of the hand (suffering palmar dysesthesia that waking from sleep at night) were enrolled in the study. Hands were randomized into two groups using simple randomization. The first group comprised patients whose surgical candidacy was evaluated without electrodiagnostic tests, and the second group comprised patients whose surgery decisions were based on the results of electrodiagnostic testing. The patients were evaluated at 1, 3, and 12 months postoperatively. Results: Sixty-one hands were randomized to the first group and 40 hands were randomized to the second group. Four cases in the second group received medical treatment because their electrodiagnostic test results were within the normal limits, despite the presence of typical CTS symptoms. There were no differences in favor of the second group regarding any evaluation criteria during the entire follow-up period; however, the first group reported significantly more positive outcomes regarding awakening at the 3-month follow-up and regarding satisfaction at the 1-month follow-up. Conclusion: Additional electrodiagnostic tests may not be mandatory to clinically identify classical CTS or make surgical decisions in these cases. However, many cases may be caused by entrapment of the median nerve in the carpal tunnel, but they may lack typical CTS symptoms, such as waking from night-time sleep. In such cases, properly applied electrodiagnostic tests may be of immense help.

Novel Endoscopic Approach for Carpal Tunnel Syndrome: Functional Outcomes - A Prospective Study

Abstract Introduction: Carpal tunnel syndrome (CTS), a common entrapment neuropathy, can cause debilitating symptoms affecting hand function and sleep. While conservative treatments are initially attempted, surgical intervention becomes necessary for severe cases. The study introduces endoscopic carpal tunnel release (ECTR) as a minimally invasive alternative to open procedures to enhance patient outcomes. Methods: A prospective study from January 2019 to January 2022 investigated arthroscope-assisted carpal tunnel release for CTS. Patients with chronic medical conditions were excluded. The surgical procedure involved local anesthesia, a 1.5 cm incision, flexor retinaculum release under arthroscopic guidance, and postoperative care. Outcomes were assessed using the Global Symptom Scoring Scale (GSS). Results: The affected population (n = 60) had a mean age of 47.58 years, with 42 females and 18 males. Common symptoms included numbness (43.3%), paresthesia (35%), and weakness (13%). Most patients (67.1%) had no comorbidities. Complications were minimal (5.0% paresthesia, 1.7% scar tenderness, and 3.3% infection). The mean preoperative GSS was 38.57, reducing significantly (P &lt; 0.001) to 4.6 at 12 months’ follow-up. Conclusion: The study demonstrates the efficacy and safety of ECTR as a minimally invasive alternative for severe cases of CTS. With a low rate of complications and significant improvement in symptoms, including numbness, paresthesia, weakness, and surgeon expertise remains vital for successful outcomes.

The Diagnostic Value of the Median Nerve Sonography in Chronic Phase Carpal Tunnel Syndrome Cases in Indonesia

Background. Ultrasound evaluation on the median nerve in carpal tunnel syndrome (CTS) patients by measuring cross-sectional area (CSA) is widely known. However, studies have shown that CSA of the median nerve could vary in different demographical factors. Therefore, the cut-off CSA value for CTS in the Indonesian population could be significantly different. Purpose. To compare mean CSA of the median nerve between normal and CTS populations and establish a cut-off point of CSA to diagnose CTS. Materials and Methods. A comparative cross-sectional study was conducted involving 40 people divided equally into CTS and normal groups. Normal and CTS subjects are determined by Electrodiagnostic study (EDx) using EMG and Nerve Conduction Study (NCS). The CSA measurement was performed at the level of the carpal tunnel inlet. Results. The mean CSA value at the level of tunnel inlet of the normal group was 8.3 ± 1.4 mm2 and for the CTS group is 15.4 ± 4.4 mm2. The receiver operating characteristics (ROC) analysis showed 10.6 mm2 as the cut-off point with 95% sensitivity and 95% specificity (P&lt;0.001). Conclusion. The median nerve CSA at the tunnel inlet is significantly larger in the CTS population and the cut-off point can be recommended in detecting CTS in the Indonesian population.

A Comparative Analysis Between Ultrasound and Electromyographic and Nerve Conduction Studies in Diagnosing Carpal Tunnel Syndrome (CTS): A Systematic Review and Meta-Analysis.

Carpal tunnel syndrome (CTS) is the most common upper extremity neuropathy. The disease initially manifests as a sensory disorderin the form of paresthesia, numbness, or tingling of the fingers. The diagnosisis usually made based on history and clinical symptoms, which are confirmed using nerve conduction studies (NCS) and electromyography. More recently, ultrasound has gained more use in CTS diagnosis due to its advantages, which include patients' comfort during diagnosis, better visualization of anatomy and nerve forms directly, and cost-effectiveness. However, a literature review shows that the diagnostic accuracy of ultrasound over NCS is still in question; therefore, the present systematic review was carried out to compare the diagnostic accuracy of ultrasound to NCS and electromyography. A systematic literature search was performed on five electronic databases: PubMed, Medline, Web of Science, Embase, and Google Scholar. The search strategy limited the retrieval of literature published between 2000 and 2022. Of the 1098 articles retrieved from the electronic databases, only 12 met the inclusion criteria. A meta-analysis of outcomes from the included studies showed that thepooled sensitivity and specificity of the ultrasound were 0.80 (95% CI: 0.73, 0.88) and 0.90 (0.83, 0.96), respectively. On the other hand, combing the outcomes of electromyography and NCS resulted in sensitivity and specificity values of 0.89 (95% CI: 0.84, 0.95) and 0.77 (95% CI; 0.64, 0.90), respectively. The results show that ultrasound has comparable sensitivity and slightly higher specificity than NCS and electromyography; therefore, ultrasound can be used as an alternative diagnostic test for CTS. However, it cannot replace NCS and electromyography since more research needs to be done on doubtful and secondary cases of CTS.

Role of power Doppler and gray-scale ultrasound of the median nerve in the evaluation of carpal tunnel syndrome: A comparative analysis between sonographic and surgical measurements of the median nerve

Background: Carpal tunnel syndrome (CTS) is the prevalent cause of pain, numbness, tingling, and weakness. It is known that whenever the median nerve, a major peripheral nerve of the upper limb, originating from the forearm into the palm of the hand, becomes pressed or squeezed at the wrist, it leads to a condition commonly known as CTS. Aims and Objectives: The present study has been objectively conducted to assess the role of grey scale and power Doppler ultrasound of the median nerve at the wrist in evaluating CTS. The comparative analysis between USG findings and surgical findings of median nerve in CTS will also be made. Materials and Methods: The present prospective study has been conducted at the SKIMS-MC, Srinagar for a period of 6 months from January 2022 to June 2022 in the Department of Radio diagnosis and Imaging in association with the Department of Orthopedics. A total of 30 patients have been included in the study. The cases were referred from Department of Orthopedics with clinically characterized CTS. Results: Out of total 30 patients; 03 (10%) were males and 27 (90%) were females with a male to female ratio of 1:9. We observe that vascularity of median nerve was present in (56.7%) and absent in (43.3%) patients. The median nerve thinning and indentation were reflected by (80%) patients and the same was absent among (20%) patients, we did not find any agreement between surgical and sonographic parameters with the mean difference of 2.527 mm between sonographic and intraoperative perimeters, the difference was statistically significant (P&lt;0.001, CI 95%). Conclusion: The present study demonstrated that ultrasonography aided with power Doppler precisely detected CTS cases. Evidently, we find a significant difference between surgical and sonographic parameters with the mean difference of 2.527 mm between sonographic and intraoperative perimeters.

Prevalence Of Carpal Tunnel Syndrome Among Butchers In Pakistan

Carpal Tunnel Syndrome (CTS) is an ailment in which median nerve is trapped in carpal tunnel and as a result a person feels tingling, numbness, and weakness in the wrist joint. It is most caused when excessive pressure is applied on the wrist joint. Most of the professionals go through this condition because of the nature of their work. Hairdresser, dentists, and labourers are commonly affected by this condition. Objective: This study determines the prevalence of CTS among butchers in Pakistan. Methods: Butchers from different cities of Pakistan were selected to check out the prevalence of CTS. 400 butchers from different cities of Pakistan were selected. Observational study design was carried out and convenient sampling was used to collect the data. The butchers having the age of 20 to 40 years were included with having an experience of 3 years or more. All the butchers should use the manual instruments during the processing of meat. They were told about the purpose of our research and a consent form, personally designed CTS diagnosis questionnaire, Visual Analog Scale (VAS) and Boston Carpal Tunnel Syndrome Questionnaire (BCTSQ) were filled by them. Functional limitations and symptoms severity of butchers with CTS were also assessed. Results: The prevalence of CTS among butchers in Pakistan was 10.3%. The butchers having age between 26-30 years had 46% cases of CTS among them. 21-25 years old butchers had 17% of affected butchers among them. According to experience, butchers having 3-5 years’ experience was the most affected among them. 34% butchers of 3-5 years’ experience were involved. There was moderate level of functional limitation in CTS affected butchers according to BCTSQ. Next thing was the symptom severity with moderate level of symptoms severity was present in butchers suffering from CTS. Conclusion: The prevalence of CTS among butchers in Pakistan was 10.3%. All the butchers suffering from CTS had moderate level of intensity of pain. There was a moderate level of functional limitation and symptoms severity related to CTS affected butchers.
