Background

developmental dysplasia of the hip constitutes the most frequent affection for the development of the musculoskeletal system. In the context of radiographic diagnosis of this disease in infants, digital radiographs offer advantages that could be used for a more accurate diagnosis.

Objective

to describe the DDC_Calc software operation to perform radiographic measurements in digital format.

Methods

a technological innovation study was carried out during 2019, at the Paquito González Cueto University Pediatric Hospital, in Cienfuegos, specifically in the Orthopedics Service and with the specialists’ contribution from the "Marta Abreu" Central University’ Mathematics, Physics and Computing Faculty, Las Villas. The Viola-Jones artificial vision algorithm was used for the detection of the structures, as well as a rule-based system with a view to a diagnostic suggestion.

Results

the software integrated the necessary tools to carry out the measurements used (angles, distances, positions) in the radiographic diagnosis of developmental dysplasia of the hip. Its functionalities, requirements and operation of the application were described, based on a real clinical case, all illustrated with images.

Conclusions

the use of the software facilitates the performance of more accurate measurements by the doctor, thus guaranteeing higher quality in the diagnosis and the preservation of the initial radiographic findings, which are very useful in the radiographic follow-up of the condition in time.
