Abstract
BACKGROUND Diabetes mellitus often exists for many years prior to diagnosis, and very little is known about the role of the prediagnosis stage of metabolic impairment in contributing to hand and upper-extremity pathology. The goal of this study is to determine the prevalence of undiagnosed glucose dysregulation in patients presenting with the 2 most commonly treated conditions of the hand and wrist. METHODS A retrospective study was performed of hand surgery patients with no established diagnosis of prediabetes or diabetes referred for a 2-hour glucose tolerance test according to American Diabetes Association criteria. Patients were divided into 3 groups: peripheral neuropathies, trigger finger, and controls with various upper-extremity diagnoses. Rates of undiagnosed prediabetes and diabetes were compared between groups, including subgroup analysis of patients based on unilateral or bilateral presentation. Binary logistic regression analysis was also used to calculate odds ratios for multiple variables. RESULTS Patients with neuropathy had a significantly higher incidence of undiagnosed dysglycemia compared with the control group. Of those patients, 51.3% were prediabetic and 12.8% were diabetic. The control group had significantly lower rates. Within the bilateral neuropathy patients, 59.6% had prediabetes and 15.4% had diabetes, versus 34.6% with prediabetes and 7.7% with diabetes in the unilateral group. CONCLUSIONS Hand surgeons encounter a patient population with high rates of undiagnosed prediabetes and diabetes, with some presentations as much as 6 times higher than the general population. Certain patient presentations should prompt appropriate diagnostic testing and referral, especially those presenting with bilateral compression neuropathy and elevated body mass index.

Abstract
BACKGROUND This study aimed to examine the relationship between anatomical surface landmarks in fresh frozen cadavers as related to in vivo endoscopic trigger finger release (ETFR) and present clinical outcomes after a single-portal antegrade ETFR technique. METHODS Endoscopic trigger finger release was performed on 40 cadaveric digits. Each digit was dissected and the following measurements were recorded: distance from palmar digital crease and A1 pulley, length of the A1 pulley, percentage of A1 pulley released, and injury to vulnerable anatomy. A retrospective chart review was performed on 48 patients (62 digits) treated with ETFR. Outcome measures included grip and pinch strength, range of motion, Disability of Arm, Shoulder, and Hand (DASH) questionnaires, and Visual Analog Scale (VAS) pain scores. RESULTS Release of the A1 pulley was achieved in 33 of the 40 cadaveric digits (83%) with an A2 pulley laceration rate of 25%. No flexor tendon or neurovascular injuries occurred. Gross grasp, lateral pinch, 3-jaw chuck, and precision pinch strength had 85%, 90%, 82%, and 90% recovery, respectively. At the final follow-up, average metacarpophalangeal joint, proximal interphalangeal joint, and distal interphalangeal joint range of motion were within the normal limits. Mean VAS scores decreased from 5.7 preoperatively to 1.0 postoperatively and mean DASH score at the final follow-up was 4.8. CONCLUSIONS With the use of anatomical surface landmarks, ETFR may be performed in an efficient and reproducible manner. Patients treated with ETFR had low complication rates, good functional recovery, and improved pain at short-term follow-up. Further study of long-term outcomes and cost-effectiveness of ETFR is warranted.

Abstract
PURPOSE We hypothesized that increased friction between the flexor tendon and surrounding structures due to hand arthritis is an important risk factor for trigger finger (TF) after carpal tunnel release (CTR). Therefore, we compared TF development according to the presence or absence of arthritis in carpal tunnel syndrome (CTS) patients treated with CTR. METHODS This retrospective study was based on data collected from the National Health Insurance Service-National Sample Cohort (NHIS-NSC) in the Republic of Korea between January 1, 2002, and December 31, 2015. Patients diagnosed with TF between one month and one year after the CTR date or with a history of surgery were included in the study. During subsequent follow-up, the patients were divided into subgroups of those (1) with TF and (2) without TF. Sex, age, arthritis, and TF-related comorbidities were compared between the subgroups. RESULTS The subgroup with TF had a higher proportion of women (9.43% vs 90.57%), the highest age range between 50 and 59 years, more cases of arthritis (32.55% vs 16.79%), and a higher proportion of patients with hypothyroidism (10.85% vs 4.60%) than the group without TF. The association between arthritis and TF after CTR was examined using a multivariate logistic regression model, showing arthritis to be a significant risk factor for TF after CTR (odds ratio, 1.35; P = 0.049). CONCLUSIONS We identified arthritis as an important risk factor for the development of TF after CTR.

Abstract
INTRODUCTION Trigger finger (TF) often occurs after carpal tunnel release (CTR), but the mechanism and outcomes remain inconsistent. This study evaluated the incidence of TF after CTR and its related risk factors. MATERIALS AND METHODS PubMed, Embase, and Scopus databases were searched up to 27 August 2022, with the following keywords: "carpal tunnel release" and "trigger finger". Studies with complete data on the incidence of TF after CTR and published full text. The primary outcome was the association between CTR and the subsequent occurrence of the TF and to calculate the pooled incidence of post-CTR TF. The secondary outcomes included the potential risk factors among patients with and without post-CTR TF as well as the prevalence of the post-CTR TF on the affected digits. RESULTS Ten studies with total 10,399 participants in 9 studies and 875 operated hands in one article were included for meta-analysis. CTR significantly increases the risk of following TF occurrence (odds ratio=2.67; 95% CI 2.344-3.043; P <0.001). The pooled incidence of TF development after CTR was 7.7%. Women were more likely to develop a TF after CTR surgery (odds ratio=2.02; 95% CI 1.054-3.873; P =0.034). Finally, the thumb was the most susceptible fingers, followed by middle and ring fingers. CONCLUSIONS High incidence of TF comes after CTR, and women were more susceptible than man. Clinicians were suggested to notice the potential risk of TF after CTR in clinical practice. LEVEL OF EVIDENCE Level III, meta-analysis.

Abstract
Background: Trigger digit(s) (TD) is one of the most common disorders of the hand in the elderly population. The aim of this study is to determine the prevalence and identify the risk factors for TD in an elderly Japanese population. Methods: We randomly sampled 1,297 subjects between the ages of 50 and 89 years from the population registry of a town in Japan. About 413 subjects agreed to participate in the study, and all were examined for the presence of TD. Subjects were divided into three groups namely history of treatment for TD in the past (PTD), current evidence of TD (CTD) or both (BTD). The prevalence of TD was weighted by age according to the composition of the Japanese population. Age, female gender, obesity, hard manual work, exposure to vibration tools, sports activity, smoking, alcohol, wrist fracture, hypertension, hypothyroidism, diabetes mellitus, rheumatoid arthritis and carpal tunnel syndrome were assessed as risk factors for TD using univariate and multivariate logistic regression analysis. Results: Forty subjects had TD. This included 18, 19 and 3 subjects with PTD, CTD and BTD, respectively. The weighted prevalence of TD was 9.7% (female, 14.3%; male, 4.4%) in the Japanese population aged 50-89 years. Age 70-79 and female gender were identified as risk factors for TD. Conclusions: The random sampling of a Japanese population registry between the ages of 50 and 89 years revealed the prevalence of TD as 9.7% and identified age between 70 and 79 and female gender as risk factors for developing TD. Level of Evidence: Level II (Therapeutic).

Abstract
The interventional use of sonography is growing fast, and percutaneous sonographically guided release is more and more used as minimally invasive treatment of carpal tunnel syndrome as well as trigger finger digit. The benefits of these procedures seem promising in clinical studies, but biomechanical studies comparing these procedures with open classical surgery are scarce. Minimally invasive releases of carpal tunnel and trigger finger could limit the phenomenon of tendon bowstringing observed after open surgery. A new model is presented to compare the biomechanical effects of open and sono-guided carpal tunnel and trigger finger releases.

Abstract
INTRODUCTION 'The diabetic hand' has traditionally referred to hand complications due to diabetes mellitus (DM), including trigger finger (TF) and Dupuytren's disease (DD). Recent publications have also proposed DM as a risk factor for carpal tunnel syndrome (CTS), ulnar nerve entrapment (UNE), and possibly osteoarthritis (OA) of the first carpometacarpal (CMC-1) joint. This study aimed to explore prevalence and incidence of diabetic hand complications among the population in southern Sweden. RESEARCH DESIGN AND METHODS Approximately 1.1 million inhabitants in the region of Skåne aged ≥18 years, whereof 50 000 with DM, were included. Data on incident CTS, UNE, TF, DD, and OA of the CMC-1 joint between 2004 and 2019 were collected from the Skåne Healthcare Register and cross-linked with the National Diabetes Register. Prevalences on December 31, 2019 and 10-year incidence ratios were calculated for type 1 diabetes (T1D), type 2 diabetes (T2D), and the population without DM, stratified for sex. Prevalence ratios and incidence rate ratios with 95% CIs were used for group comparisons. RESULTS The prevalences of all five studied diagnoses were higher in both men and women with T1D and T2D (p<0.01) and both T1D and T2D had more concomitant prevalent diagnoses (p<0.0001). The 10-year incidence rates of all diagnoses were higher among T1D and T2D (p<0.0001), except OA of the CMC-1 joint in men with T1D (p=0.055). CONCLUSIONS CTS, UNE, and possibly also OA of the CMC-1 joint should be included together with TF and DD when referring to 'the diabetic hand'. The incidence of hand disorders was up to eight times higher among T1D, and both T1D and T2D had more concomitant prevalent diagnoses compared with the population without DM. Future studies should elucidate the pathophysiology behind diabetic hand complications to enable development of effective preventive measures in patients with diabetes.

Abstract
Carpal tunnel syndrome (CTS) is one of the most common peripheral neuropathies caused by chronic compression of the median nerve in the area of the carpal tunnel and its etiology is multifactorial. Trigger fingers and de Quervain’s disease are common disorders of the hand related to CTS in adults.Theaim of this study was to present the most common disorders of the hand such as stenosing tenosynovitis in adults with surgically treated CTS and to evaluate their demographic data.Material and methods: A total of 116 surgically treated patients with established diagnosis of CTS (clinically and by electrophysiological examination) were included in this prospective study, which was conducted at the University Clinic for Orthopedic Diseases in Skopje. Demographic data, findings of history of the disease and clinical examination were recorded and analyzed.Results: Participants with CTS included in the study were with a mean age of 55.41±10.7 years (age range 29-75). 75% of them were female. 63.8% of participants suffered from one or more comorbid chronic diseases. On admission to hospital, disorders such as trigger fingers and de Quervain’s disease were concomitantly diagnosed in 15.51% on ipsilateral hand with CTS. All disorders were surgically treated following open carpal tunnel release, as “one stage procedure”, under local anesthesia.Conclusion: Our findings have determined concomitant existence of CTS and stenosing tenosynovitis (trigger fingers and de Quervain’s disease) on ipsilateral hand, which suggests common etiological factors. Female gender and age range 40-60 years are major common factors related to these three disorders.

Abstract
Diabetes has an important role in the development of several musculoskeletal disorders, such as adhesive capsulitis of the shoulder (ACs) and stenosing flexor tenosynovitis of the finger (SfTf). The etiopathophysiology of ACs and SfTf in diabetic patients is associated with both chronic hyperglycemia, increased amounts of visceral adiposity and chronic inflammation. Chronic hyperglycemia stimulates the creation of cross-links between collagen molecules, impairing degradation and resulting in the build-up of excessive collagen deposits in the cartilage, ligaments, tendon sheaths and tendons. Increased adipocytes in diabetic patients secrete proteins and cytocines such as TNF-α, IL-6 and IL-13 which result in overproduction of pro-inflammatory factors, destruction of normal tissue architecture and fibrosis. Both hyperglycemia and adipocytes inhibit efferocytosis, limiting natural resolution. Recently, multiple image-guided interventional radiology musculoskeletal treatment options have been developed, such as ultrasound-guided glenohumeral capsule hydrodistension for ACs and ultrasound-guided percutaneous pulley release for trigger finger. Diabetes can negatively influence outcomes in patients with ACs and SfTf and may impact the decision of which specific procedure technique should be employed. Further studies are necessary to define how diabetes influences response to interventional radiology treatments of these disorders, as well as the extent to which control of blood sugar levels can contribute towards the personalization and optimization of patient follow up.

Abstract
OBJECTIVE The aim of this study was to determine the incidence of hand disorders in a general rural area, record the demographic characteristics for each condition, and evaluate the tendencies overtime in the incidence of these conditions. METHODS Using nationwide census data, we identified a health network system serving a geographic area with stable population. Subsequently, we retrospectively analyzed all the patient records (n=731 patients) with hand disorders documented between 2001 and 2015. We performed a retrospective review and collected demographic data for the patients and disorders treated surgically. We calculated the incidence of these conditions based on the census data and performed qualitative and categorical analysis with different demographic and disease-related variables. RESULTS We reviewed surgically treated 204 male and 527 female patients with hand disorders. The mean annual incidence was 222.5 cases per 100,000 individuals per year. More than 55% of the patients were between 50 and 69 years old. Trigger finger (TF) accounted for approximately 42% of patients, followed by 35% with carpal tunnel syndrome (CTS). TF and CTS were related to hand dominance, and right hand was affected in 53.4% of the patients. CONCLUSION Hand disorders in a rural area seem to correlate with the occupational sector activities, such as farming and agriculture. CTS was the most common disorder in the past; however, the dramatic increase in the incidence rate of TF made it the most common hand disorder in the last decade. Incidence rates in both males and females showed an increasing trend.

Abstract
Surgical treatment of carpal tunnel syndrome (CTS) was recently started in our department, and we noticed that the development of trigger finger (TF), with which neurosurgeons are generally unfamiliar, is not rare after such treatment. We summarized the clinical and pathogenetic aspects of TF and retrospectively analyzed the medical records of all 39 patients who underwent CTR in our department to investigate the occurrence of TF. In 39 patients with CTS, 46 surgical interventions were performed in our department. All surgical procedures were carried out by open release of the transverse carpal ligament under local anesthesia infiltration, but the distal forearm fascia was not released. The mean postoperative follow-up period was 21.1 ± 16.8 months. TF after CTR occurred in nine hands of eight patients (9 of 46 hands, 19.6%). The mean interval between CTR and TF onset was 5.3 ± 2.8 months. TF after surgical treatment of CTS is not rare; therefore, surgeons who treat CTS should understand the clinical features of TF and carefully assess affected patients, particulary at presentation and within 6 months postoperatively.

Abstract
BACKGROUND Trigger digit is a common disorder of the hand associated with carpal tunnel syndrome. Carpal tunnel release (CTR) surgery may be a risk factor for trigger digit development; however, the association between surgical approach to CTR and postoperative trigger digit is equivocal.
AIM To investigate patient risk factors for trigger digit development following either open carpal tunnel release (OCTR) or endoscopic carpal tunnel release (ECTR).
METHODS This retrospective chart analysis evaluated 967 CTR procedures from 694 patients for the development of postoperative trigger digit. Patients were stratified according to the technique utilized for their CTR, either open or endoscopic. The development of postoperative trigger digit was evaluated at three time points: within 6 mo following CTR, between 6 mo and 12 mo following CTR, and after 12 mo following CTR. Firth’s penalized likelihood logistic regression was conducted to evaluate sociodemographic and patient comorbidities as potential independent risk factors for trigger digit. Secondary regression models were conducted within each surgical group to reveal any potential interaction effects between surgical approach and patient risk factors for the development of postoperative trigger digit.
RESULTS A total of 47 hands developed postoperative trigger digit following 967 CTR procedures (4.9%). In total, 64 digits experienced postoperative triggering. The long finger was most commonly affected. There was no significant difference between the open and endoscopic groups for trigger digit development at all three time points following CTR. Furthermore, there were no significant independent risk factors for postoperative trigger digit; however, within group analysis revealed a significant interaction effect between gender and surgical approach (P = 0.008). Females were more likely to develop postoperative trigger digit than males after OCTR(OR = 3.992), but were less likely to develop postoperative trigger digit than males after ECTR (OR = 0.489).
CONCLUSION Patient comorbidities do not influence the development of trigger digit following CTR. Markedly, gender differences for postoperative trigger digit may depend on surgical approach to CTR.

Abstract
Trigger finger (TF) is a common referral to a hand surgeon, with people with diabetess being the most at-risk population. Abnormal thickening, scarring, and inflammation occur at the A1 pulley and flexor tendon, and histological changes correlate well with the clinical severity of TF. Corticosteroid injections decrease the thickness of the A1 pulley and are considered a first-line treatment. However, corticosteroids are only moderately effective, especially for people with diabetes. Patients may elect for surgery if nonoperative treatments prove ineffective; some may choose immediate surgical release instead. To release the A1 pulley, patients have the option of an open or percutaneous approach. The open approach has a greater risk of infection and scar tissue formation in the short run but an overall superior long-term outcome compared with the percutaneous approach. METHODS We critically reviewed the efficacy and cost-effectiveness of the treatment methods for TF through a comprehensive search of the PubMed Database from 2003 to 2019. RESULTS To reduce costs, while still delivering the best possible care, it is critical to consider the likelihood of success for each treatment method in each subpopulation. Furthermore, some patients may need to return to work promptly, which ultimately may influence their desired treatment method. CONCLUSIONS Currently, there is no universal treatment algorithm for TF. From a purely financial standpoint, women without diabetes presenting with a single triggering thumb should attempt 2 corticosteroid trials before percutaneous release. It is the most cost-effective for all other subpopulations to elect for immediate percutaneous release.

Abstract
INTRODUCTION Trigger finger (TF) is a frequent pathology depending on several factors. The objective of this study was to assess the relationship between multiple TF and systemic or musculoskeletal disorders in a sample of young patients. MATERIAL AND METHOD A retrospective study was performed of all patients with TF operated in our hospital between 2011 and 2015. Multiple or single TF diagnosis and pathologies such as diabetes mellitus (DM), thyroid dysfunction, carpal tunnel syndrome (CTS), epicondylalgia or DeQuervain's disease were collected. Statistical results included a bivariate analysis and a multiple logistic regression. RESULTS Two hundred and seventy-nine patients with a mean age of 48.45years were included. The dominant hand was affected in 217 cases. There were 59 patients with multiple TF, 21 DM, 55 STC, 16 epicondylalgia and 14 DeQuervains. Prevalence of CTS was 19.7%, significantly higher than the general population (2%-4%). No statistical differences were found in age, sex, hypothyroidism, epicondylalgia or DeQuervain in the multiple TF group. Bivariate analysis detected that DM and CTS patients in the multiple TF group was significantly higher than in the single TF group (P=.007, P<.01). Multiple TF was also more frequent on the dominant side (P<.01). Multivariate logistic regression confirmed these findings, showing a statistically significant association between the multiple TF group and DM (OR: 4.98, P<.01), STC (OR: 2.09, P=.037) and dominant side (OR: 3.76, P=.016). CONCLUSIONS Diabetes, CTS and dominant side are independently associated with multiple TF in young patients.

Abstract
Diabetics have a much greater prevalence of trigger finger than nondiabetics and are more likely to have severe symptoms. Diabetic trigger finger may be more accurately described on a spectrum of diabetic hand pathology alongside carpal tunnel syndrome and cheiroarthropathy. Recent publications have called into question the current treatment algorithm for diabetic trigger finger. Although some evidence supports the use of corticosteroid injections, a recent cost analysis reported that immediate surgical release of the A1 pulley in the clinic is the most cost-effective management of diabetic trigger finger. In addition to traditional treatment with injection and open release, percutaneous release with or without simultaneous corticosteroid injection has shown promising results and may have a role in patient care. The appropriate treatment algorithm in terms of efficacy, safety, and cost remains controversial.

Abstract
PURPOSE Carpal tunnel syndrome and trigger finger (TF) frequently present concomitantly; some studies suggest that carpal tunnel release (CTR) is a risk factor for the development of ipsilateral TF in the postoperative period. The primary objective of this study was to elucidate the relationship between CTR and the subsequent development of TF. METHODS A retrospective study was conducted of 1,386 hands in 1,140 patients who underwent primary CTR at a tertiary referral center from July 2008 to June 2013. After exclusion of cases in which contralateral CTR was performed within the first postoperative year after ipsilateral CTR, conditional logistic regression was performed in 906 hands in 890 patients to determine the association between CTR and TF in the first postoperative year in the operative hand compared with the contralateral hand. Conditional logistic regression and Poisson regression were performed in 1,386 hands in 1,140 patients to examine the association between CTR and TF in the year before surgery compared with the year after surgery. Multivariable regression analysis was used to determine associated risk factors. RESULTS Of 1,386 hands, a new TF was seen in 147 (10.6%) within 1 year before CTR and 81 (5.8%) within 1 year after CTR. The occurrence of postoperative TF was associated with 2.5 times higher odds in the operative hand compared with the contralateral hand in the conditional logistic regression model of 906 cases. However, the incidence of TF was associated with 0.5 times lower odds during the year after CTR compared with the year before CTR in both conditional logistic regression and Poisson regression models of 1,386 cases. Increased body mass index is statistically associated with TF after CTR, but the attributable risk is negligible. CONCLUSIONS There is a predisposition for these 2 common hand pathologies to present in the same hand; however, patients can be counseled that CTR does not cause new incidence of TF in the operative hand. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic IV.

Abstract
De Quervain's disease, carpal tunnel syndrome (CTS), and trigger finger (digit) are three common pathological conditions of the hand. They are considered overuse syndromes and occur predominantly in females. The prevalence rate and cause-specific risks of these three tendinopathies have not yet been clarified. Data from 41,871 cases listed in the Taiwan National Health Insurance Research Database (NHIRD) from 2010 to 2014 were analyzed. The prevalence rate of these 3 conditions by age, sex, and the risk factors of female-dominant diseases (e.g., osteoporosis, rheumatoid arthritis [RA], and tendinopathy), diabetes mellitus, and hormone antagonist treatment was evaluated. We found that 1.59% of the population developed CTS, 0.49% developed de Quervain's, and 1.07% developed trigger finger. Cases were more likely to develop the three hand tendinopathies if they were female, between 50 and 59 years old, and, according to a multivariate analysis, comorbid with RA, diabetes, using hormone antagonists. Our findings should provide an understanding of the risk factors associated with hand tendinopathy.

Abstract
BACKGROUND Carpal tunnel syndrome (CTS) and trigger digits are among the most common nontraumatic hand disorders treated by plastic surgeons. The onset of trigger digits after carpal tunnel release (CTR) has been inconsistently reported. This systematic review assessed the prevalence of trigger digits development in patients after CTR surgery. METHODS We searched the MEDLINE, EMBASE and SCOPUS databases for papers published between January 1966 and August 2016. Eligible studies contained quantitative data on the incidence of trigger digits after CTR. The primary outcome measure was the onset of trigger digits after CTR. The secondary outcome measure was the prevalence of digital involvement in patients who developed trigger digits after CTR. RESULTS A total of 5654 CTR surgeries were performed in the included nine studies, and 483 patients (8.5%) developed trigger digits after CTR. The reported incidence of trigger digits after CTR ranged from 5.2% to 31.7%. The time to development of trigger digits was approximately 6 months postoperatively. In the eight observational studies and in the randomized controlled trial, the thumb and ring finger were reported as the most commonly involved trigger digits, respectively. CONCLUSIONS The incidence of trigger digits after CTR surgery is not negligible. Thumbs and ring fingers are the most commonly involved digits. This topic should therefore be suitably addressed during preoperative consultations.

Abstract
The aim of this study was to assess the overall and cause-specific incidences of diabetic hand syndromes (DHS) in patients with diabetes mellitus (DM) by using age and sex stratifications.The DM and control cohorts comprised 606,152 patients with DM and 609,970 age- and sex-matched subjects, respectively, who were followed up from 2000 to 2008. We estimated the incidence densities (IDs) of overall and cause-specific DHS, namely carpal tunnel syndrome (CTS), stenosing flexor tenosynovitis (SFT), limited joint mobility (LJM), and Dupuytren disease (DD), and calculated the hazard ratios (HRs) of DHS in relation to DM by using a Cox proportional hazards model with adjustment for potential confounders.Over a 9-year period, 51,207 patients with DM (8.45%) and 39,153 matched controls (6.42%) sought ambulatory care visits for various DHS, with an ID of 117.7 and 80.7 per 10,000 person-years, respectively. The highest cause-specific ID was observed for CTS, followed by SFT, LJM, and DD, regardless of the diabetic status. After adjustment for potential confounders, patients with DM had a significantly high HR of overall DHS (1.51, 95% confidence interval [CI] = 1.48-1.53). Men and women aged <35 years had the highest HR (2.64, 95% CI = 2.15-3.24 and 2.99, 95% CI = 2.55-3.50, respectively). Cause-specific analyses revealed that DM was more strongly associated with SFT (HR = 1.90, 95% CI = 1.86-1.95) and DD (HR = 1.83, 95% CI = 1.39-2.39) than with CTS (HR = 1.31, 95% CI = 1.28-1.34) and LJM (HR = 1.24, 95% CI = 1.13-1.35).Men and younger patients with DM have the highest risk of DHS. Certain hand syndromes, such as SFT and DD, were more strongly associated with DM than with other syndromes and require the attention of clinicians.

Clin Orthop Relat Res 2015; 473:2371-82. [PMID: 25690168 PMCID: PMC4457761 DOI: 10.1007/s11999-015-4189-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2014] [Accepted: 02/03/2015] [Indexed: 02/09/2023]
Abstract
BACKGROUND The impaired sensory function of the hand induced by carpal tunnel syndrome (CTS) is known to disturb dexterous manipulations. However, force control during daily grasping configuration among the five digits has not been a prominent focus of study. Because grasping is so important to normal function and use of a hand, it is important to understand how sensory changes in CTS affect the digit force of natural grasp. QUESTIONS/PURPOSES We therefore examined the altered patterns of digit forces applied during natural five-digit grasping in patients with CTS and compared them with those seen in control subjects without CTS. We hypothesized that the patients with CTS will grasp by applying larger forces with lowered pair correlations and more force variability of the involved digits than the control subjects. Specifically, we asked: (1) Is there a difference between patients with CTS and control subjects in applied force by digits during lift-hold-lower task? (2) Is there a difference in force correlation coefficient of the digit pairs? (3) Are there force variability differences during the holding phase? METHODS We evaluated 15 female patients with CTS and 15 control subjects matched for age, gender, and hand dominance. The applied radial forces (Fr) of the five digits were recorded by respective force transducers on a cylinder simulator during the lift-hold-lower task with natural grasping. The movement phases of the task were determined by a video-based motion capture system. RESULTS The applied forces of the thumb in patients with CTS (7 ± 0.8 N; 95% CI, 7.2-7.4 N) versus control subjects (5 ± 0.8 N; 95% CI, 5.1-5.3 N) and the index finger in patients with CTS (3 ± 0.3 N; 95% CI, 3.2-3.3 N) versus control subjects (2 ± 0.3 N; 95% CI, 2.2-2.3 N) observed throughout most of the task were larger in the CTS group (p ranges 0.035-0.050 for thumb and 0.016-0.050 for index finger). In addition, the applied force of the middle finger in patients with CTS (1 ± 0.1 N; 95% CI, 1.3-1.4 N) versus the control subjects (2 ± 0.2 N; 95% CI, 1.9-2.0 N) during the lowering phase was larger in CTS group (p ranges 0.039-0.050). The force correlations of the thumb-middle finger observed during the lowering phase in the patients with CTS (0.8 ± 0.2; 95% CI, 0.6-0.9) versus the control subjects (0.9 ± 0.1; 95% CI, 0.8-1.0; p = 0.04) were weaker in the CTS group. The thumb-little finger during holding in the patients with CTS (0.5 ± 0.2; 95% CI, 0.3-0.7) versus the control subjects (0.8 ± 0.2; 95% CI, 0.6-0.9; p = 0.02), and the lowering phase in the patients with CTS (0.6 ± 0.2; 95% CI, 0.3-0.8) versus the control subjects (0.9 ± 0.1; 95% CI, 0.8-1.0; p = 0.01) also were weaker. The force variabilities of patients with CTS were greater in the CTS group than in the control subjects: in the thumb ([0.26 ± 0.11 N, 95% CI, 0.20-0.32 N] versus [0.19 ± 0.06 N; 95% CI, 0.16-0.22 N], p = 0.03); index finger ([0.09 ± 0.07 N; 95% CI, 0.05-0.13 N] versus [0.05 ± 0.03 N; 95% CI, 0.04-0.07 N], p = 0.03); middle finger ([0.06 ± 0.04 N; 95% CI, 0.04-0.08 N] versus [0.03 ± 0.01 N; 95% CI, 0.02-0.04 N], p = 0.02), and ring finger ([0.04 ± 0.03 N; 95% CI, 0.20-0.06 N] versus [0.02 ± 0.01 N; 95% CI, 0.02-0.02 N], p = 0.01). CONCLUSIONS Patients with CTS grasped with greater digit force associated with weaker correlation and higher variability on specific digits in different task demands. These altered patterns in daily grasping may lead to secondary problems, which will need to be assessed in future studies with this model to see if they are reversible in patients undergoing carpal tunnel release. CLINICAL RELEVANCE The current results helped to identify altered patterns of grasping force during simulated daily function in patients with CTS and to provide the clinician with potential information that might help guide the rehabilitation of grasp in these patients.
