Occurrence Of Carpal Tunnel Syndrome Research Articles

Association Between Thenar Musculature and Carpal Tunnel Syndrome.

Background: Dynamic forces acting on the transverse carpal ligament (TCL) may influence the mechanics of the carpal tunnel (CT), thus affecting the occurrence of CT syndrome (CTS). Previous studies demonstrated an association between muscle overlying the CT and the diagnosis of CTS. Understanding the location of insertion/origin of the thenar musculature will allow mechanical analysis of the forces applied to the TCL during performance of individual tasks. Our purpose was to determine the location of muscle overlying the CT on magnetic resonance imaging (MRI) in CTS and controls. Methods: Case-control study of 21 normal adult wrist MRI scans. MRI measurements were performed on an axial cut at the level of the hook-of-hamate. Median nerve cross-sectional area (CSA), median nerve shape and increased signal intensity within the CT were associated with CTS. The amount and length of muscle crossing the midline and the CT on the same cut was measured and the association with the occurrence of CTS was analysed. Results: We found an inverse relationship between the amount of muscle crossing the midline and the size of the CT, and a direct relationship with occurrence of CTS p less than 0.01, but no differences regarding length of muscle crossing the midline. Conclusions: This study supports an association between the thenar musculature location relative to the CT and the predictors of CTS on MRI. Since the location of muscle origin/insertion is variable, their effect may differ accordingly, therefore, further study is needed to describe the exact location of origin/insertion and its differential dynamic or static effect on the pathogenesis of CTS. Level of Evidence: Level IV (Diagnostic).

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>.

Correlation between Palmaris Longus Muscle and Carpel Tunnel Syndrome in Badminton Players

Background: Carpal Tunnel Syndrome (CTS) is commonly observed in athletes, especially those engaged in sports involving repetitive wrist activities. The role of the Palmaris Longus Muscle (PLM) in the development of CTS has been a subject of interest due to its anatomical location. Objective: To examine the correlation between the presence or absence of the PLM and the incidence of CTS among badminton players. Methods: In this cross-sectional study, 258 badminton players aged 18-23 years were assessed. Players with a history of carpal tunnel release surgery were excluded. The presence of the PLM was evaluated using Schaeffer’s test, while Phalen’s test was used to diagnose CTS. Statistical analysis involved chi-square tests to determine the association between PLM and CTS. Results: Of the participants, 193 (74.8%) had a positive Schaeffer’s test (indicating the presence of PLM), and of these, 72 (37.3%) also had a positive Phalen’s test (indicative of CTS). Conversely, among the 65 (25.2%) with a negative Schaeffer’s test, only 10 (15.4%) had a positive Phalen’s test. The chi-square analysis yielded a P-value of 0.001, indicating a statistically significant association between the presence of PLM and the occurrence of CTS. Conclusion: There is a significant correlation between the presence of the Palmaris Longus Muscle and the development of Carpal Tunnel Syndrome in badminton players. These findings underscore the importance of considering anatomical variations in PLM during the assessment and management of CTS in athletes.

Activities involving intensive use of hands over an extended period are often associated with the occurrence of Carpal Tunnel Syndrome (CTS). According to the 2013 ILO report, CTS is consistently detected in almost every incident of work-related diseases in several countries. One type of occupation at risk of CTS is online motorcycle taxi drivers. The aim of this study is to determine the relationship between characteristics, medical history, and obesity with CTS complaints in the Online Motorcycle Taxi Community of the Ciracas District, East Jakarta, in the year 2022. The study design is cross-sectional. The sample consists of 107 online motorcycle taxi drivers from the Ciracas District. The research was conducted from April to September 2022. Data collection was done using questionnaires. Data analysis included univariate, bivariate (Chi-square test), and multivariate (Logistic Regression test). The research findings reveal that respondents with CTS complaints in the at-risk category are 29.9%. The majority of respondents are below 40 years old (52.3%), have a work experience of less than 4.5 years (51.4%), work for more than 8 hours per day (59.8%), have no medical history (59.8%), and are not obese (71.0%). The bivariate analysis results show that variables significantly associated with CTS complaints include work experience (p = 0.012 and OR = 3.3), work duration (p = 0.021 and OR = 3.297), medical history (p = 0.046 and OR = 2.571), and obesity (p = 0.049 and OR = 2.654). The multivariate analysis results indicate that there is no single dominant factor with the highest influence on CTS complaints within the online motorcycle taxi community (p &gt; 0.05). The recommendation is to provide Health Education to online motorcycle taxi drivers regarding preventive measures for CTS complaints. This aims to help them manage their work schedule effectively and take preventive actions against CTS issues, such as regular breaks, supportive nutrition, and so forth.&#x0D; Keywords: characteristics, medical history, obesity, Carpal Tunnel Syndrome (CTS) complaints, Online Motorcycle Taxi

Body mass index and carpal tunnel syndrome: A case-control study.

To investigate the electrophysiological characteristics of carpal tunnel syndrome (CTS) and to evaluate the relationship between electrophysiological indexes and body mass index (BMI). In the analysis of 153 hospitalized patients with CTS, the median motor conduction velocity, motor conduction amplitude, motor conduction latency, sensor conduction velocity, sensor conduction amplitude and median sensory latency were analyzed. BMI was calculated. Total 171 healthy individuals were selected as control group. According to Guidelines for Prevention and Control of Overweight and Obesity in Chinese Adults, patients were divided into groups A, B and C. Patients with BMI (kg/m2) <24 were classified into group A; those with 24 ≤ BMI < 28 were regarded as overweight and classified into group B; and those with BMI ≥ 28 were regarded as obese and classified into group C. The BMI of CTS patients was significantly higher than that of healthy individuals (P < .05). For the sensory nerve, with the increase of BMI, the incubation period was gradually prolonged and the conduction velocity gradually decreases (P < .05). In terms of motor latency, with an increase in BMI, the latency showed a trend of first decreasing and then increasing, while the conduction velocity showed a trend of first increasing and then decreasing (P < .05). Electrophysiological examination plays an important supporting role in the diagnosis of CTS. BMI is positively correlated with the degree of CTS injury to a certain extent. Weight loss can effectively prevent the occurrence of CTS and slow the progression of nerve damage in CTS patients.

Serum Transforming Growth Factor β1 and Its Genetic Variants Are Associated with Increased Macrophage Inflammatory Protein 1β and Susceptibility to Idiopathic Carpal Tunnel Syndrome.

Carpal tunnel syndrome (CTS) is a common entrapment neuropathy in which one of the body's peripheral nerves becomes pinched or crushed. Transforming growth factor beta 1 (TGF-β1) plays an important role in the pathogenesis of CTS. An association between TGF-β1 polymorphisms and the susceptibility or progression of a number of diseases has been reported. In this study, three TGF-β1 single nucleotide polymorphisms (SNPs), serum TGF-β1, and macrophage inflammatory protein 1 beta (MIP-1β) were investigated as potential diagnostic markers for the progression of CTS in Egyptian patients. One hundred CTS patients and 100 healthy controls were recruited for the study. TGF-β1 SNPs +915G/C, -509C/T and -800G/A were determined by TaqMan genotyping assay. Serum TGF-β1 and MIP-1β levels were measured by ELISA. Serum TGF-β1 and MIP-1β levels increased significantly and were strongly correlated with the occurrence of CTS. The C allele of +915G/C, the T allele of -509C/T, and the G allele of -800G/A occurred more frequently in patients from CTS than in controls. The serum levels of TGF-β1 and MIP-1β in the group of carriers of the genotypes +915G/C GC and CC, the genotype -509C/T TT and the genotype -800G/A GA and AA were significantly higher in CTS patients. TGF-β1 and its +915G/C, -509C/T, and -800G/A SNPs and MIP-1β could be useful prognostic markers for the occurrence of CTS.

Association between carpal tunnel syndrome and trigger finger: a clinical and electrophysiological study

BackgroundCarpal tunnel syndrome is a prevalent mononeuropathy. Trigger finger is a flexor stenosing tenosynovitis. The aim of the study was to assess the concomitant occurrence of carpal tunnel syndrome and trigger finger in the same hand among patients presented with idiopathic carpal tunnel syndrome or idiopathic trigger finger. The study included 110 hands (75 patients) presented with carpal tunnel syndrome or trigger finger and 60 asymptomatic hands (46 apparently healthy individuals). Clinical assessment and neurophysiological evaluation were done.ResultsRegarding the presenting clinical complaints, there were 76 hands (69.1%) from 48 patients (64.0%) presented with idiopathic carpal tunnel syndrome. There 34 hands (30.9%) from 27 patients (36.0%) presented with idiopathic trigger finger. Classification of the patients into three groups depending on the final diagnosis: (I) carpal tunnel syndrome group, 57 hands (51.8%) with only carpal tunnel syndrome from 36 patients (48.0%); (II) trigger finger group, 25 hands (22.7%) with only trigger finger from 22 patients (29.3%); and (III) carpal tunnel syndrome with trigger finger group, 28 hands (25.5%) with both conditions from 24 patients (32.0%); and among them, seven patients had contralateral hand carpal tunnel syndrome only. The duration of complaints among the carpal tunnel syndrome with trigger finger group was significantly shorter than that in the other two groups. There were statistically significantly higher values of patient global assessment of hand symptoms and effect of hand symptoms on function and quality of life among the carpal tunnel syndrome with trigger finger group versus the other two groups. There was no statistically significant difference between the carpal tunnel syndrome with trigger finger group versus the carpal tunnel syndrome group regarding different classes of the Padua neurophysiological classification scale. The most common digit to have trigger finger was the middle finger in 19 hands (35.8%).ConclusionsThe concurrent presentation of idiopathic carpal tunnel syndrome and idiopathic trigger finger in the same hand is common. Each of them could be associated with the other one. The symptoms of one of them usually predominate the patient’s complaints. The identification of this association is essential for proper diagnosis and comprehensive management of patients presented with these conditions.

The Myth of Median Nerve in Forearm and Its Role in Double Crush Syndrome: A Cadaveric Study.

Purpose: This study aims to histologically compare the median nerve in the arm, forearm, and wrist, to help understand how cervical radiculopathy in a double crush phenomenon causes distal nerve dysfunction at the carpal tunnel and median nerve with concurrent absence of symptoms at the forearm.Methods: The study was performed on 12 fresh cadaveric upper limbs free from any injury or operation. Male cadavers in the age range of 35–40 years were used. The dissection of the median nerve and the histological examination of the specimens from the arm, forearm, and wrist were conducted to evaluate variations in the epineurium thickness (μm), perineurium thickness (μm), number of fascicles per nerve trunk, area percent of myelin covering, and area percent of neurolemmal sheath.Results: Morphometric and statistical results of the cadaveric median nerve trunk revealed that the mean epineurium and perineurium thickness measured in H&E-stained sections in the forearm were significantly greater than those in the arm and wrist specimens. Further, the mean percent area of the myelin covering in the forearm was significantly lower than that in the arm and wrist specimens in the sections stained with osmium oxide (p < 0.001). There were, however, no significant differences in the neurolemmal sheath among the arm, forearm, and wrist specimens in the silver-stained sections.Conclusion: The histological differences explained the high concomitant occurrence of carpal tunnel syndrome (CTS) and cervical radiculopathy and the concurrent absence of symptoms at the forearm. Hence, we suggest cautious evaluation of patients with upper limb symptoms, since the management of these conditions requires a different approach.

Risk factors related to complications of the fingers and hand after arthroscopic rotator cuff repair - carpal tunnel syndrome, flexor tenosynovitis, and complex regional pain syndrome.

Hypothesis/BackgroundComplications involving the fingers and hand after arthroscopic rotator cuff repair (ARCR) include complex regional pain syndrome, carpal tunnel syndrome (CTS), and flexor tenosynovitis (TS). The aims of this study were to diagnose the complications after ARCR and investigate the risk factors that could predispose individuals to these finger and hand complications.MethodsFifty patients (50 shoulders) who underwent ARCR participated in this study. The patients’ ages ranged from 36 to 84 years (mean, 63 years). Before ARCR, we determined the disease history of the fingers and hand (CTS or TS) and subjectively assessed their symptoms using a questionnaire that included a scale ranging from 1 (no symptoms or no disability) to 5 (the worst symptoms or severest disability). ARCR was performed in all patients using suture anchors. The mean observation period after surgery was 15.5 months (range, 12-48 months). We diagnosed complications involving the fingers and hand after ARCR and investigated the preoperative, intraoperative, and postoperative risk factors that could predispose patients to these complications using univariable and multivariable analyses.ResultsAfter ARCR, 20 patients (20 hands) (40%) had complications of the fingers and hand. Among them, the diagnosis was CTS in 2 hands, TS in 15 hands, and both CTS and TS in 3 hands. None of the hands exhibited complex regional pain syndrome. These complications occurred at an average of 1.8 months (range, 0.1-4 months) after ARCR. In the 47 patients who did not have symptoms just before the operation, both univariable and multivariable analyses between the complication group (n = 17) and the no-complications group (n = 30) showed a significant difference in the presence of a past history of CTS or TS (complication frequency: past history: 88%, no past history: 25%) (P < .05) and the preoperative subjective assessment for edema of the fingers and hand (complication frequency: edema ≥ 2 points: 89%, edema < 2 points: 24%) (P < .05). There were no relationships between the other candidate intraoperative and postoperative factors and complications.ConclusionIn all 20 hands with complications of the fingers and hand after ARCR, the diagnosis was CTS or TS. Complications of the fingers and hand after ARCR easily occurred in patients with a past history of CTS or TS and in patients with edema as per a subjective assessment. We speculate that the ARCR triggered the occurrence of CTS and TS postoperatively in patients who had subclinical CTS or TS before surgery.

The Role of Multifactorial Contribution in Carpal Tunnel Syndrome Occurrence

As one of the common peripheral neuropathies, carpal tunnel syndrome (CTS) is accountable for the majority of typical hand pain and functional disturbance in median nerve innervation. The median nerve compression may cause some uncomfortable sensations including pain, numbness, tingling, and strength loss which also depends on the severity of the condition. Many factors could contribute to CTS occurrence. Several risk factors are thought to be in charge in CTS progressions, such as body mass index (BMI), gender, pregnancy, and biomechanical exposures combination is significantly explained as the major component in suffering CTS. Clinicians need to know the contributing risk factor to benefit the information within the implication for the treatment and reducing symptoms severity. Keywords: carpal tunnel syndrome, risk factor, multifactor.

Clinical and Electrophysiological Profile of Carpal Tunnel Syndrome: A Study in a Tertiary Care Hospital

Introduction: Carpal tunnel syndrome (CTS) is a clinical syndrome that results from compression of median nerve within the carpal tunnel at the wrist. The aim of this study was to review the clinical and demographic characteristics and electrophysiological patterns of CTS patients who presented to a tertiary care hospital in Bangladesh.&#x0D; Methodology; A descriptive cross-sectional study was conducted on 150 CTS patients at the neurology department, Dhaka Medical College Hospital between January, 2019 to March , 2020 . All the subjects had clinical evaluation and standardized nerve conduction studies of upper limbs (300 limbs) using the same protocol.&#x0D; Results: 228 hands were found to have clinical and electrophysiological features consistent with CTS. There was female predominance (90%) and the highest occurrence of CTS was in the 45-55 years age group. Bilateral CTS was found in the majority of cases ie 78 (52%) and the rest had unilateral CTS. Among those with unilateral CTS, right hand was affected more (41, 57%) than left hand (31, 43%). Most of the cases were idiopathic. Neurophysiological studies showed most patients had mild CTS (121 hands, 53%). Most of the cases were idiopathic (102, 68%). Where a risk factor was found diabetes was commonest one (32) followed by hypothyroidism (12) and pregnancy (4).&#x0D; Conclusion: There was marked female predominance and the 45-55 years age group was predominantly affected. Majority of cases had mild CTS. Bilateral involvement was more common. Right hand was more affected than the left hand.&#x0D; J Dhaka Medical College, Vol. 29, No.2, October, 2020, Page 96-99

Association between smartphone use and carpal tunnel syndrome: A case-control study.

Context:Carpal tunnel syndrome (CTS) is a common entrapment neuropathy of the upper limb. No published Saudi Arabian study has explored the effect of smartphones on the median nerve.Aim:To assess the association between smartphone use and the development of CTS.Settings and Design:This case-control study involved adults aged 18 years and older who visited King Khalid University Hospital (KKUH) in Riyadh, Saudi Arabia.Materials and Methods:Patients were clinically diagnosed with CTS, and the diagnosis was confirmed by a nerve conduction study (NCS) and electromyography. The controls were free of CTS based on the disease-specific Boston Carpal Tunnel Questionnaire. Statistical analyses were performed using IBM-SPSS version 25.0.Results:In total, 95 cases and 190 controls were included. Most of the participants were females (84.2%). The mean ages in the controls and cases were 34.6 +/– 10.2 years and 51.8 +/– 10.6 years, respectively. Using smartphones for 2 hours per day or more was significantly associated with the occurrence of CTS. After adjusting for covariates, 4 hours or more per day of smartphone use was associated with CTS. Moreover, those who held the smartphone with both hands had 7.8 times higher odds of developing CTS than those who held it with one hand.Conclusion:CTS has a negative impact on patients’ daily activities and work. This study showed that an increased number of hours of smartphone use is associated with the development of CTS. Further prospective studies are needed to examine the long-term effects of smartphone use.

Demographics of Patients Undergoing Carpal Tunnel Release in an Urban Tertiary Hospital in Malaysia.

Introduction: Carpal tunnel syndrome (CTS) is the most commonly encountered neuropathy. The entrapment of the median nerve at the wrist can be corrected with a carpal tunnel release (CTR) procedure. The objective of this retrospective study was to determine the demographic, medical, and surgical characteristics of the patients with CTS who presented for CTR surgery in a tertiary hospital in Malaysia.Materials and Methods: Malaysians patients with CTS who had undergone a CTR during the period from 1st June 2017 to 31st December 2017 were enrolled into the study. Each patient had a minimum follow-up of three months. The demographic data of age, gender, race and occupation, and the comorbid illnesses and associated risk factors were recorded. The prevalence and occurrence of CTS in the dominant or non-dominant hand and the effectiveness of surgical intervention were also noted. Data was collected, analysed and stored in Microsoft Excel and SPSS 25.Results: There was a total of 76 cases of CTR surgeries done in 62 patients in the study. Eighty percent of the patients were female, and most of the patients belonged to the age group of 41-60 years. Malays constituted 74.2% of the patients, and 34% were housewives. Hypertension, dyslipidaemia and diabetes mellitus were the three major comorbidities. Cervical spondylosis was seen in one-fourth of the patients. Bilateral hand involvement was present in 54.8% of patients. 59.7% of CTR surgery was done on the dominant hand alone, 17.7 % CTR on the non-dominant hand alone and 22.6% CTR on both hands. Numbness and pain (50%) were the predominant presenting symptoms. The most positive signs were the Durkan test (77.6%), followed by the Tinel sign at the carpal tunnel and the Phalen’s test. At follow-up, three months or more, after the surgery, 75% of the patients showed a satisfactory improvement.Conclusion: Patients, who had undergone CTR, had a higher prevalence of pre-morbid conditions, and a quarter of them presented with associated cervical spondylosis. The most common presentation was a combination of numbness and pain. Many obtained satisfactory improvement post-surgery and thus open surgery could be considered a reliable treatment for CTS.

Familial occurrence of carpal tunnel syndrome.

The objective of this study was to investigate the incidence of familial carpal tunnel syndrome in patients admitted to the authors' institution for carpal tunnel release. Questionnaires completed by 120 patients: 92 women (77%) and 28 men (23%) at a mean age of 56 years at their baseline clinical examination were reviewed. Familial occurrence of the disease was noted in 21 patients (17%): 16 women and five men. Three family members were affected in three patients, two relatives in eight patients, and one relative in 10 patients, giving a total of 35 affected relatives. The patients' sisters (n = 16) were the most commonly involved, followed by mothers (n = 12), daughters (n = 2), brothers (n = 2), grandmothers (n = 2) and an aunt (n = 1). Bilateral manifestation of the disease was noted in 19 patients (90%) and in 31 (88%) of their affected relatives. The results suggest that carpal tunnel syndrome shows a moderate tendency to familial occurrence and, if so, it usually manifests bilaterally.
