“…The syndrome affects an estimated 2.7% of the population [2,3,7,8,13]. Overall prevalence of CTS in the United States may affect as many as 1.9 million people and may account for 500,000 surgical procedures annually, with costs over $2 billion [12].…”

This study investigated whether body mass index (BMI) was associated with effectiveness of carpal tunnel release as measured by physical and self-assessment tests. This prospective, longitudinal study was conducted from March 2001 to March 2003 using 598 cases (hands) diagnosed with carpal tunnel syndrome and scheduled for surgery at The Curtis National Hand Center, Baltimore, Maryland, and at the Pulvertaft Hand Centre, Derby, England. Body mass index was calculated, and demographic, clinical, and functional data were collected preoperatively and at 6-month follow-up. Grip, pinch, and Semmes-Weinstein scores were measured preoperatively and at 6-month follow-up. Levine-Katz self-assessment scores for symptom severity and functional status were measured preoperatively and at 6-month follow-up. Grip and pinch increased, whereas Semmes-Weinstein, symptom severity, and functional scores decreased by 6-month follow-up. Cases with BMI >35 had lower grip strength and higher symptom severity in males and higher functional status in both sexes pre-and postoperatively compared to normalweight BMI cases. BMI had no relationship to patient satisfaction. Although morbidly obese cases did worse on some physical and self-assessment tests compared to normal BMI cases preoperatively, all improved to the same extent postoperatively regardless of BMI.

“…CTS is progressive and produces numbness, pain, swelling, and weakness of hands, causing significant inconvenience for patients. The prevalence of CTS has been reported from 1 to 3 % in a general population [1], and there is some evidence indicating that the incidence of CTS is increasing [2]. Moreover, about 400,000 procedures of carpal tunnel release, which is the most common hand and wrist surgery, are performed in the USA per year [2].…”

A Knowledge-Based Approach for Carpal Tunnel Segmentation from Magnetic Resonance Images

Carpal tunnel syndrome (CTS) has been reported as one of the most common peripheral neuropathies. Carpal tunnel segmentation from magnetic resonance (MR) images is important for the evaluation of CTS. To date, manual segmentation, which is time-consuming and operator dependent, remains the most common approach for the analysis of the carpal tunnel structure. Therefore, we propose a new knowledge-based method for automatic segmentation of the carpal tunnel from MR images. The proposed method first requires the segmentation of the carpal tunnel from the most proximally cross-sectional image. Three anatomical features of the carpal tunnel are detected by watershed and polygonal curve fitting algorithms to automatically initialize a deformable model as close to the carpal tunnel in the given image as possible. The model subsequently deforms toward the tunnel boundary based on image intensity information, shape bending degree, and the geometry constraints of the carpal tunnel. After the deformation process, the carpal tunnel in the most proximal image is segmented and subsequently applied to a contour propagation step to extract the tunnel contours sequentially from the remaining cross-sectional images. MR volumes from 15 subjects were included in the validation experiments. Compared with the ground truth of two experts, our method showed good agreement on tunnel segmentations by an average margin of error within 1 mm and dice similarity coefficient above 0.9.

“…The prevalence of this disorder has been estimated between one and five percent in the general population [1][2][3] with higher estimated rates of 10% or more reported among workers in some industries [4][5][6]. The direct costs for treatment and indirect costs for lost work time and permanent functional disability make this syndrome costly for patients as well as employers [7,8].…”

Prevalence of Carpal Tunnel Syndrome in a General Population

Abstract: Symptoms of pain, numbness, and tingling in the hands are common in the general population. Based on our data, 1 in 5 symptomatic subjects would be expected to have CTS based on clinical examination and electrophysiologic testing.
