RESUMO
OBJECTIVES: To collate and synthesise the literature to provide estimates of the diagnostic accuracy of imaging modalities, and summarise the reported imaging findings associated with de Quervain's syndrome. MATERIALS AND METHODS: A systematic search was performed in seven databases (MEDLINE, EMBASE, CINAHL, Cochrane Library, PROSPERO, Web of Science, and ProQuest Dissertations & Theses Global). Two reviewers independently performed screening, data extraction and quality assessment using a modified Quality Assessment of Diagnostic Accuracy Studies-2. Measures of diagnostic accuracy were summarised for different modalities and imaging findings. RESULTS: Twenty-two studies were included, reporting ultrasound, magnetic resonance imaging, X-ray and scintigraphy findings. Reported imaging findings included sheath effusion, retinaculum thickening, subcutaneous oedema, tenosynovitis, hypervascularity, increased tendon size, bony erosion, apposition, calcific lesions and increased uptake on scintigraphy. The most commonly reported imaging findings related to the tendon sheath, with a sensitivity ranging from 0.45 to 1.00 for thickening, and 0.29 to 1.00 for effusions. The risk of bias of studies is largely unclear owing to a lack of reported detail. CONCLUSIONS: The accuracy of imaging in the diagnosis of de Quervain's syndrome is unable to be determined because of the quality of the studies included. Ultrasound is the most frequently studied imaging modality and may be the modality of choice in clinical practice. Further research involving both symptomatic and asymptomatic participants and clear definitions of abnormal findings are required to better evaluate the effectiveness of imaging in identifying de Quervain's syndrome.

RESUMO
Background: De Quervain syndrome is the second most common compressive tendinopathy. Although the length of the first extensor compartment (FEC) has been studied previously, there is no documented reported comparison study of short-axis and long-axis sonographic measurements. The thread technique, or Guo Technique, has been applied to carpal tunnel syndrome, trigger finger, and superficial peroneal compressive neuropathy. To perform this procedure, it is critically important to accurately identify the boundaries for transection. Methods: Twenty-one fresh frozen cadaver upper extremities were examined under ultrasound to determine the length of the extensor retinaculum (ER) over the FEC. Using the sonographic landmarks, the ERs were measured in short axis and long axis over their proximal to distal margins and from the distal margins to the distal edges of the radial styloids. These sonographic measurements were then compared with gross anatomical measurements. Results: The short-axis sonographic measurement of the ER on average was 22.53 mm (95% confidence interval [CI] = 20.79-24.05 mm). The long-axis sonographic measurement of the ER on average was 15.65 mm (95% CI = 13.70-17.78 mm). The average length of the ER by gross anatomical dissection was 22.40 mm (95% CI = 21.15-23.51 mm). Conclusions: The short axis is not significantly different from the gross anatomical measurement; however, the long axis is significantly lower than the gross anatomical measurement. The results support the idea that the short axis is more accurate than the long axis.

OBJECTIVE: Both physical diseases such as infection and chronic pain and psychological disorders such as depression have been associated with herpes zoster (HZ) reactivation. However, the relationship between de Quervain syndrome (DQS), a painful tenosynovitis and HZ remains unclear. We investigated whether DQS increases the risk of HZ reactivation. DESIGN: A retrospective population-based cohort study. SETTING: Taiwan. PARTICIPANTS: We used a subset of Taiwan's National Health Insurance Research Database, the Longitudinal Health Insurance Database which contains the registration files and original claims data of 1 million randomly selected individuals from the National Health Insurance programme. The case group in this study comprised patients newly diagnosed with DQS between 2000 and 2012. Individuals without DQS comprised the control group. Cases and controls were 1:1 matched by age, sex and index year (defined as the year of DQS diagnosis). RESULTS: Approximately 55% of the participants were ≤49 years. Most participants were women (77%). The incidence rate of HZ in the DQS group was 8.39 per 1000 person years. After adjustments for age, sex and comorbidities, patients with DQS had a 1.30 times higher risk of HZ reactivation than the control group. Stratification analysis revealed taht DQS increases the HZ risk in individuals ≤64 years, women, and patients without comorbidities. CONCLUSION: DQS is associated with an increased risk of HZ. Clinicians should be aware of this risk when dealing with patients with DQS, particularly in young adults.

The primary aim of this study is to describe medium-term functional outcomes following first dorsal compartment decompression using a longitudinal incision in patients with de Quervain's syndrome. The secondary aims are to describe the improvement in health-related quality of life and patient satisfaction, and to determine the cost-effectiveness of this procedure. Pre- and postoperative QuickDASH, EQ-5D-5 L, and satisfaction scores were collected prospectively over five years. Paired data were available for 36 patients (90% at mean 32 months follow-up). The median QuickDASH score improved significantly from 50 to 9.1 (p < 0.01). Median EQ-5D-5L index scores improved from 0.65 preoperatively to 0.73 (p = 0.03). The satisfaction rate was 97% and there were no cases of superficial radial nerve injury or neuroma. The cost per quality-adjusted life year gained was £356 (398; $449). First dorsal compartment release using a longitudinal incision results in a significant improvement in function, with high levels of patient satisfaction, and low complication rates. In addition, health economic analysis revealed that this is a cost-effective procedure for the treatment of de Quervain's syndrome. LEVEL OF EVIDENCE: III (cohort study).

Muscle and tendon variations in the forearm, wrist and hand are commonly reported in the anatomical and surgical literature. They are frequently the source of inflammatory conditions such as de Quervain's tenosynovitis or carpal tunnel syndrome. During academic dissection, a cadaver presented with bilateral, additional muscles running parallel to the abductor pollicis longus muscles (APL) in the extensor compartment of the forearm. Both additional muscles had two bellies, one proximal and one distal, with an intervening tendon. The proximal bellies were separate and distinct from the adjacent APLs. The tendons traversed the first dorsal compartments with the tendons of the APLs and the extensor pollicis brevis muscles (EPB). The distal bellies lay adjacent to the abductor pollicis brevis (APB) muscles in the thenar compartments, and inserted onto the volar base of the proximal phalanges of the thumbs. Following a thorough search of the literature, we determined that these additional muscles constitute a previously unreported variation. This report details the variation, compares it with other reported variations, presents the related embryology, and reviews the significance of this variation as it relates to inflammatory conditions and surgical procedures.

Objective For patients with De Quervain syndrome using thumb spica orthosis is restricting, so many patient are dissatisfied with using static model. The aim of this study is to compare the effect of modified dynamic and conventional static orthoses on pinch power and functional abilities of hand in De Quervain syndrome. Method In this quasi-experimental study, palmar and lateral pinch strength of the thumb, pain and functional abilities of hand, patient's satisfaction of orthoses, were evaluated after using modified dynamic and conventional static orthosis in two groups. Results Both orthoses improved palmar and lateral pinch strength of the thumb, pain level and functional abilities. In comparison of mentioned variables, there was no significant difference between two groups regarding to pain recovery and abilities improvement (p > 0.05). However, the satisfaction level of the patients who had used dynamic orthosis was higher (p < 0.05). Conclusion It seems, adding a joint to the static thumb spica leads to patient's relief and consequently to their satisfaction. Implications for Rehabilitation The dynamic thumb spica, is easier to use and patients satisfaction is higher than static thumb spica. Therefore, it can be used for conservative treatment of De Quervain syndrome.

UNLABELLED: The purpose of this study was to find clinical or ultrasound characteristics that might predict the failure of conservative treatment in de Quervain's syndrome. A total of 42 ultrasound-guided injections have been performed in 41 patients after clinical and ultrasound examination. Patients were immobilized for 3 weeks with a spica splint cast, and clinically evaluated at 3 and 6 weeks and by phone call at the end of the study. Ultrasound showed a septum between the tendons of the first comportment in 34% of the wrists. At last follow-up (mean 15.6 months after the injection) ten patients (24%) had undergone surgery. When comparing ultrasound and clinical characteristics of the operated and non-operated wrists, we found that patients with a high baseline visual analogue scale, with all positive clinical tests and with a persistent intracompartmental septum, had a significantly higher risk of failure following conservative treatment. LEVEL OF EVIDENCE: III.

Tendinopathies involving the hand and wrist are common. Many are diagnosed easily, and in many cases, the management is straightforward, provided the pathology and principles are understood. Common conditions involving the tendons of the hand and wrist include trigger finger, tenosynovitis of the first through sixth dorsal extensor compartments, and flexor carpi radialis tendonitis. Management strategies include nonsurgical treatments, such as splinting, injection, or therapy, and surgical techniques such as tendon release.

BACKGROUND: The primary aim of this study was to determine predictors of missed research appointments in a prospective randomized placebo injection-controlled trial with evaluations 1 to 3 and 5 to 8 months after enrollment. METHODS: This study represents a secondary use of data from 104 patients that were enrolled in a prospective randomized controlled trial of dexamethasone versus lidocaine (placebo) injection for various diagnoses. Patients were enrolled between June 2003 and February 2008. Sixty-three patients (61%) had lateral epicondylosis, 17 patients (16%) had trapeziometacarpal arthrosis, and 24 patients (23%) had de Quervain syndrome. Each patient completed a set of questionnaires at time of enrollment. Bivariable and multivariable analyses were used to determine factors associated with missed research appointments. RESULTS: Fourteen patients (13%) did not return for the first follow-up and 33 patients (32%) did not return for the second follow-up. The best multivariable logistic regression model for missing the first research visit explained 35% of the variability and included younger age, belief that health can be controlled, and no college education. The best model for missing the second research visit explained 17% of the variability and included greater pain intensity, less personal responsibility for health, and diagnosis (trapeziometacarpal arthrosis and de Quervain syndrome). CONCLUSIONS: Younger patients with no college education, who believe their health can be controlled, are more likely to miss a research appointment when enrolled in a randomized placebo injection-controlled trial.
RESUMO
BACKGROUND: This study tested the null hypothesis that type of injection (corticosteroid vs. placebo) is not a predictor of arm-specific disability as measured with the Disabilities of Arm, Shoulder and Hand questionnaire 1 to 3 months after injection of dexamethasone or placebo for treatment of trapeziometacarpal (TMC) arthrosis or de Quervain syndrome. Secondly, we tested if type of injection was a predictor of pain intensity. METHODS: Thirty-six English-speaking adults with TMC arthrosis or de Quervain syndrome were randomized for a dexamethasone or a placebo injection. At time of the injection, patients completed a demographic data sheet and validated questionnaires assessing arm-specific disability, pain intensity, depressive symptoms, pain catastrophizing, and patient's health-related beliefs. At an average of 1.4 ± 0.42 months (range, 0.79-2.5 months) after the injection, patients completed questionnaires regarding arm-specific disability, pain, and treatment satisfaction. Grip and pinch strength measurements were measured at both time points. Bivariable and multivariable analyses assessed predictors of arm-specific disability and pain intensity at follow-up. RESULTS: Type of injection was not a predictor of arm-specific disability or pain intensity 1 to 3 months after injection. The best model both for arm-specific disability and pain intensity at follow-up included pain catastrophizing and explained 18 % and 33 % of the variability, respectively. CONCLUSIONS: Catastrophic thinking was a better predictor of both of arm-specific disability and pain intensity than diagnosis or type of injection (steroid vs. placebo) 1to 3 months after an injection.
RESUMO
The Abductor Pollicis Longus (APL) is known to have a big variety in its number of insertion tendons.Because of that, studies about variations in its origin are not frequently achieved like studies about its insertionforms. This study describes an anatomic variation of the Abductor Pollicis Longus, with an anomalous venteroriginated of the inferior portion of the lateral border of the radio. Surgical and clinical implications are inrelation principally with the big number of tendons of insertion of the APL, but there are related cases inthe literature in that additional venter of this muscle also can be involved in the physiopathology of clinicalsyndromes, like the tenosynovitis of de Quervain

Anatomical variations of abductor pollicis longus and extensor pollicis brevis are important in clinical assessment of diseased and traumatized hand. The present case reports an unusual fusion of muscle bellies of abductor pollicis longus and extensor pollicis brevis with two separate tendons of insertion, the medial tendon inserted into the base of first metacarpal and the lateral tendon into the abductor pollicis brevis muscle. Knowledge of such anatomical variations is of utmost importance in the management of De Quervain's disease and reconstructive surgeries of hand.
