“…Also, despite previously established thresholds, considerable overlap with healthy wrists exists (McCarroll et al., 2008, 2010). Hegazy et al. (2019) recently developed a modified 2-D technique using the capitate as a bony landmark instead of the ulna, observing an improved inter-and intra-rater agreement for some, but not all measurements.…”

In the diagnostic work-up of Madelung deformity conventional radiographic imaging is often used, assessing the three-dimensional deformity in a two-dimensional manner. A three-dimensional approach could expand our understanding of Madelung deformity’s complex wrist anatomy, while removing inter- and intra-rater differences. We measured previous two-dimensional-based and newly developed three-dimensional-based parameters in 18 patients with Madelung deformity (28 wrists) and 35 healthy participants (56 wrists). Madelung deformity wrists have increased levels of ulnar tilt, lunate subsidence, lunate fossa angle, and palmar carpal displacement. The lunate fossa is more concave and irregular, and angles between scaphoid, lunate, and triquetral bones are decreased. These findings validate the underlying principles of current two-dimensional criteria and reveal previously unknown anatomical abnormalities by utilizing novel three-dimensional parameters to quantify the radiocarpal joint.

“…In an additional experiment for accuracy verification, four examiners used the same method on five hands of five healthy volunteers. Previous reports were referred for the number of raters, and accordingly, the number was set to be equal to or to exceed the number included in these reports [ 38 , 39 , 40 ].…”

Research into hand-sensing is the focus of various fields, such as medical engineering and ergonomics. The thumb is essential in these studies, as there is great value in assessing its opposition function. However, evaluation methods in the medical field, such as physical examination and computed tomography, and existing sensing methods in the ergonomics field have various shortcomings. Therefore, we conducted a comparative study using a carbon nanotube-based strain sensor to assess whether opposition movement and opposition impairment can be detected in 20 hands of volunteers and 14 hands of patients with carpal tunnel syndrome while avoiding existing shortcomings. We assembled a measurement device with two sensors and attached it to the dorsal skin of the first carpometacarpal joint. We measured sensor expansion and calculated the correlation coefficient during thumb motion. The average correlation coefficient significantly increased in the patient group, and intrarater and interrater reliability were good. Thus, the device accurately detected thumb opposition impairment due to carpal tunnel syndrome, with superior sensitivity and specificity relative to conventional manual inspection, and may also detect opposition impairment due to various diseases. Additionally, in the future, it could be used as an easy, affordable, and accurate sensor in sensor gloves.

“…El carpo permanece subluxado volar y cubitalmente, y, debido al aplanamiento de la fisis cubital del radio distal, se produce el arqueamiento de la diáfisis anterior radial. [16][17][18][19][20] La superficie de la articulación radial muestra una desviación cubital promedio de 60°en la vista anteroposterior (los valores normales son de $ 23°), y una inclinación volar de 35°en la vista lateral (normal: 11°). El ángulo entre el radio y el tercer hueso metacarpiano, generalmente de 5°, es mayor de 15°en la DM.…”

[16][17][18][19][20][21] Los cambios antes mencionados, cuando se identifican de forma aislada, no justifican el diagnóstico y, por lo tanto, McCarroll et al 16 han determinado patrones radiográficos que, sumados, proporcionan un alto valor predictivo positivo para el diagnóstico de la DM.

Madelung deformity (MD) comprises an increased volar and ulnar tilt of the joint facet of the distal radius, secondary to an idiopathic physeal dysplasia. Such change causes radial shortening and consequent distal ulnar prominence, along with wrist pain and loss of motion. Surgery becomes an option in patients with severe deformity that do not respond to conservative treatment.The classic surgical techniques are problematic for adults, as they are specific for children and adolescents, whose radial physis is still open. Very few papers discuss the treatment of adult patients; furthermore, most are focused on the distal radioulnar joint, and thus do not approach the origin of the pathology.When analyzing computed tomography scans with tridimensional reconstruction, a feature of MD, growth arrest of the volar and ulnar portions of the distal radius, is noted, causing the typical distal radius deformity that leads to lack of coverage of the lunate bone. That leads to palmar subluxation of the lunate bone and consequent radiocarpal instability.We herein describe the possibilities of treatment in different stages of evolution, summarizing the authors' view on MD.
