Background: De Quervain's tenosynovitis is a stenosing tenosynovitis of the first extensor compartment of wrist and leads to wrist pain and impaired function of wrist and hand.  The aim of this study is to evaluate the role of high resolution ultrasonography in diagnosing suspected cases of de Quervain’s tenosynovitis and also to evaluate the role of high resolution ultrasonography in detecting the anatomical variants of the first extensor compartment which are predisposing conditions for de Quervain’s tenosynovitis.Methods: A prospective study of 15 consecutive cases who were referred with clinical diagnosis of de Quervain`s disease was done with ultrasonography in the department of Radio-diagnosis and findings were carefully analysed.Results: Thickened extensor retinaculum over the first extensor compartment was found in all the cases. Mean thickness of the thickened retinaculum is 1.65 mm. In 60% of cases multiple slips of APL tendon were found.Conclusions: From the study, we conclude that extensor retinaculum thickening is a common finding in de Quervain`s disease.

Abstract Background To evaluate the diagnostic accuracy of high-resolution ultrasound in the assessment of abdominal wall masses and mass-like lesions and to provide an overview of the sonographic appearances of different abdominal wall pathologies, 54 patients were included in a prospective study. The patients’ age was ranging from 1 to 75 years. Twenty-eight were females (51.9%) and 26 were males (48.1%); all were evaluated by a high-resolution ultrasound examination, and the results were correlated to the patients’ operative findings and histopathological results as well as the pelviabdominal CT findings. Results In comparison to the operative, histopathological, and CT findings, the high-resolution ultrasound had an overall 100% accuracy for abdominal wall lesions, and for hernia cases, it had 100% sensitivity, 100% specificity, 100% accuracy, 100% positive predictive value, and 100% negative predictive value. Conclusion The current study had encouraging results regarding the role of high-resolution ultrasound in the assessment of abdominal wall masses and mass-like lesions; nevertheless, it is considered as an effective and simple diagnostic tool that may limit the patients’ exposure to invasive biopsies and to the hazardous exposure to ionizing radiation and contrast media administration like that in CT examination.

Extensor Compartment

<p class="abstract"><strong>Background:</strong> First extensor compartment of the wrist comprises of abductor pollicis longus and extensor pollicis brevis. It helps in movement and stabilization of thumb. Variations in the number of tendons of APL muscle may be asymptomatic and often incidental finding. Stenosing tenosynovitis of the first dorsal compartment of the wrist or de Quervains disease is a commonly encountered debilitating condition of the wrist.</p><p class="abstract"><strong>Methods:</strong> This cadaveric study was done on 40 forearms in 20 cadavers available in Department of anatomy and forensic medicine at our institute. The muscles of extensor compartments were dissected, extensor retinaculum split over first extensor compartment, tendons of APL exposed. Study period from February-2017 to February-2018.<strong></strong></p><p class="abstract"><strong>Results:</strong> There were 6 female and 14 male cadavers. The APL muscle was found with a single tendon in 2, double in 30, triple in 8. There were variations in the insertion of the APL tendon as well. In all hands, the APL tendon had insertion into the first metacarpal bone and in 20 hands (50%), it had second insertion into the trapezium.</p><p class="abstract"><strong>Conclusions:</strong> Variation of APL muscle insertion in the Indian population and two or more tendinous slips attached commonly to the first metacarpal base and the trapezium may be the cause of treatment failure in DQT and cause of Trapeziometacarpal arthritis. Further studies needs to be done for further evaluation.</p>

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.
