A pilot project undertaken last year by Saint Petersburg State Paediatric Medical University (SPSPMU) has shown that custom orthotic insoles made using Delcam software can be used not only to correct disorders of patients’ feet but also to improve children’s posture.

The research, which was carried out on three patients, was undertaken under the supervision of Dr AA Gaiduk, chief doctor of the CDC and head of the Exercise Therapy, Physiotherapy and Sports Healthcare Department at SPSPMU. Each patient suffered problems associated with a skewed pelvis, which caused a shift in total body weight in the coronal plane and, consequently, foot overloads on the side of the pelvis skew.

For the project, Delcam Saint Petersburg installed a complete set of equipment and software for the design and manufacture of custom orthopaedic insoles, including an Iqube scanner, Orthomodel design software and the Orthomill machining system.

Initial tests on the patients were conducted using the Famus Diers diagnosis system. This has been used by orthopaedists at SPSPMU to detect postural disorders and to obtain digital and graphical data for the diagnosis and selection of relevant treatments since 2010.

Key benefits of product application

  • The patients’ feet were scanned using the Iqube scanner to obtain an accurate 3D digital model of the feet. Data from the Iqube and Famus Diers systems was combined by the orthopaedist to design the insoles within Orthomodel, which allowed consideration of the individual features of each patient, including compensation for differences in the height of the feet and the placement of correcting add-ons, such as metatarsal pads. Toolpaths for the milling machine were generated in Orthomill to manufacture the insoles.
  • The full set of tests was repeated on the three patients after they had been fitted with the insoles. The results showed significant improvement of their biomechanical poses and the state of their postures since they had been using the insoles.
  • The results of the pilot project showed that the use of the Delcam scanner and software, together with Famus Diers instrumental examination, provides not only objective diagnosis but also allows the production of height-compensating orthotics for the effective remedial treatment of children and teenagers with functional diseases of the loco-motor system.

Delcam supplies software and services that help manufacturing companies to maximise their profitability by increasing productivity, improving quality and reducing lead times. The company is the world's largest specialist supplier of computer-aided machining software, with its PowerMILL, FeatureCAM, Partmaker and ArtCAM programs making up the most comprehensive range of CAM systems from any developer.

This broad selection allows Delcam to offer a CAM system capable of machining virtually any product, in any material on any type of equipment. Delcam also develops product design, tooling design and quality control programs. The unique Tribrid Modelling approach to design incorporates solid modelling, surface modelling and triangle modelling in a single program, enabling complete design and reverse engineering projects to be undertaken without transferring data between software.

Delcam's Powerinspect offers fast, reliable comparison of parts, prototypes and tooling against CAD data on all types of inspection equipment and even on machine tools. This versatility has made it the world's leading hardware-independent inspection software. Related programs are available for checking machine tool set-up and part location. Delcam software is used in over 80 countries worldwide by around 40,000 organisations, from large multi-nationals to small sub-contractors, in industries including aerospace, automotive, dental, engineering, footwear, medical and toolmaking.
