Carpal Tunnel Syndrome (CTS) is a neuropathy disease that affects the median nerve with an incidence of around 90%. Carpal Tunnel Syndrome appears in 3.8% of the general population, with the highest prevalence occurring in women. There are several risk factors associated with CTS, namely medical and non-medical factors. The mechanism of carpal tunnel syndrome until now is still very complex and is not known with certainty, but compression and traction factors in the median nerve are thought to be the most common cause of CTS. Carpal Tunnel Syndrome can manifest clinically with subjective signs such as paresthesia, proprioceptive changes, and paresis, as well as objective signs, such as changes in motor sensitivity and function, positive Tinel and Phallen tests, and thenar muscle atrophy. The diagnosis of Carpal Tunnel Syndrome is based on the classic symptoms of pain, numbness, tingling, and/or burning sensation in the distribution of the median nerve in the hand, as well as the abnormal function of the median nerve based on nerve conduction studies. Conservative therapy is an option. Especially in Carpal Tunnel Syndrome patients with mild to moderate symptoms. Conservative therapy can be given in the form of corticosteroid and physical therapy. Patients with severe CTS or whose symptoms have not improved after four to six months of conservative therapy should be considered for surgical treatment.

Tunnel Syndrome

Recent literature has revealed a long discussion about the importance and necessity of nerve conduction studies in carpal tunnel syndrome management. The purpose of this study was to investigate the possibility of automatic detection, based on electrodiagnostic features, for the median nerve mononeuropathy and decision making about carpal tunnel syndrome. The study included 38 volunteers, examined prospectively. The purpose was to investigate the possibility of automatically detecting the median nerve mononeuropathy based on common electrodiagnostic criteria, used in everyday clinical practice, as well as new features selected based on physiology and mathematics. Machine learning techniques were used to combine the examined characteristics for a stable and accurate diagnosis. Automatic electrodiagnosis reached an accuracy of 95% compared to the standard neurophysiological diagnosis of the physicians with nerve conduction studies and 89% compared to the clinical diagnosis. The results show that the automatic detection of carpal tunnel syndrome is possible and can be employed in decision making, excluding human error. It is also shown that the novel features investigated can be used for the detection of the syndrome, complementary to the commonly used ones, increasing the accuracy of the method.

Background: Increasing severity of carpal tunnel syndrome (CTS), as graded by nerve conduction studies (NCS), has been demonstrated to predict the speed and completeness of recovery after carpal tunnel release (CTR). The purpose of this study is to compare the cross-sectional area (CSA) of the median nerve in patients with severe and nonsevere CTS as defined by NCS. Methods: Ultrasound CSA measurements were taken at the carpal tunnel inlet at the level of the pisiform bone by a hand fellowship–trained orthopedic surgeon. Severe CTS on NCS was defined as no response for the distal motor latency (DML) and/or distal sensory latency (DSL). Results: A total of 274 wrists were enrolled in the study. The median age was 51 years (range: 18-90 years), and 72.6% of wrists were from female patients. CSA of median nerve and age were comparatively the best predictors of severity using a linear regression model and receiver operator curves. Using cutoff of 12 mm2 for severe CTS, the sensitivity and specificity are 37.5% and 81.9%, respectively. Conclusions: Ultrasound can be used to grade severity in younger patients (<65 years) with a CTS-6 score of >12.

ABSTRACTWe present a case of carpal tunnel syndrome (CTS) due to compression of the median nerve within the carpal tunnel, caused by cysticercosis. Nerve conduction studies revealed severe CTS. Magnetic resonance imaging suggested an inflammatory mass compressing the median nerve in carpal tunnel. The histological diagnosis was consistent with cysticercosis. The case resolved with conservative treatment. Such solitary presentation of entrapment median neuropathy as CTS caused by cysticercosis is extremely rare. To our knowledge, this is the only case of its kind reported in literature till date.

Background Choosing cutoff values for nerve conduction studies (NCS) and ultrasound cross-sectional area (CSA) in the diagnosis of carpal tunnel syndrome (CTS) is critical in determining the diagnostic accuracy of the tests. The goals of this study were to: (1) determine the sensitivity and specificity of various electrodiagnostic and ultrasound threshold values for diagnosis of CTS; and (2) determine the number of hands that underwent NCS and ultrasound that were within 10% of threshold values. Methods A total of 309 hands of 235 patients were included in this study. Diagnosis of median neuropathy was made based on NCS by the independent physician performing the NCS. Criteria analyzed included distal motor latency of 4.4+ ms, distal sensory latency of 3.6+ ms, difference in median-ulnar mixed nerve palmar latency of 0.4+ ms, and CSA of the median nerve of 10+ mm2. Results Median neuropathy was diagnosed in 235 hands, whereas 74 hands were found not to have median neuropathy. Overall, 141 hands (46%) had at least 1 of the 3 electrodiagnostic variables within 10% of the diagnostic cutoff values, and 137 hands (44%) had a median nerve CSA within 10% of 10 mm2. By performing ultrasound in addition to NCS for each patient, an additional 65 hands (21%) had a definitive diagnosis on at least 1 of the 2 diagnostic modalities. Conclusions Ultrasound and NCS yielded a similar number of patients within 10% of their diagnostic threshold values. When used together, the number of patients with a nonborderline diagnosis on at least 1 diagnostic modality was increased substantially.

Carpal tunnel syndrome is the most common entrapment neuropathy encountered in clinical practice. It is also the most common reason for referral to the electromyography laboratory. The anatomy of the median nerve and the carpal tunnel are outlined in details in this case presentation. The recommended nerve conduction studies needed to make a diagnosis are outlined. This includes internal comparison nerve conduction studies in which the median nerve is compared to a neighboring nerve such as ulnar or radial nerves, as well as the inching studies across the carpal tunnel. Finally, special situations are emphasized including severe carpal tunnel syndrome, carpal tunnel syndrome associated with peripheral polyneuropathy, carpal tunnel syndrome in the presence of Martin–Gruber anastomosis, and carpal tunnel syndrome during pregnancy.

And Function

A prospective study of electrophysiological examination and the Boston self-administered questionnaire (BQ) was carried out in patients with surgically-treated carpal tunnel syndrome. There were 104 hands in 93 patients (13 men and 80 women, mean age 56 years). The BQ was used to assess the severity of symptoms and function, and nerve conduction studies were done before surgical release by short incision at the palm, and at follow-ups 1 and 6 months after surgery. The BQ severity score improved or became normal in 98% of hands. The mean BQ scores and distal sensory and motor conduction velocities in the median nerve showed significant improvement at the 1 month follow-up. Further significant improvement was found at 6 months. There was no relationship between the improvements in BQ scores and the distal conduction in the median nerve. The degree of improvement in sensory and motor distal conduction velocities could be forecast from presurgical values, whereas the degree of improvement in the symptoms and the functional status after release could not be predicted from the presurgical BQ scores.
