Traditional data modelling techniques of DSS and modern knowledge representation methodologies of ES are inconsistent. A new unifying model is needed for integrating the two systems into a unified whole. After a brief review of data modelling techniques and knowledge representation methodologies, the unifying model will be described and integrated systems will be used to exemplify the usefulness of the unifying model.

Minimally Invasive Reduction

Background Several minimally invasive techniques were developed for management of intraarticular calcaneal fractures. This study aimed to compare the functional and radiological outcomes of 2 minimally invasive reduction and fixation techniques using cannulated screws or Kirschner wires (K-wires) for fixation. Methods This study was a retrospective comparative review of patients with displaced intraarticular calcaneal fractures, who were treated with cannulated screws or K-wires techniques. Clinical and radiological data were collected and compared between both groups. Functional outcomes and patient satisfaction using the Maryland Foot Score (MFS) and the visual analogue scale (VAS) of pain, in addition to the complications, were compared between both groups. Results In total, 70 patients were included in the study: 34 in the cannulated screws group, with a mean age of 35.2 ± 4 years, and 36 in the K-wires groups, with a mean age of 33.4 ± 3 years. The operative time was shorter in the K-wires group (40.5 ± 5.6 minutes) compared to the cannulated screw group (49.5 ± 4.5 minutes), P < .001. There were no statistically significant differences between both groups regarding the radiological parameters, including Bohler’s angle, angle of Gissane, calcaneal width, height, or length. The mean MFS, mean VAS, and complications were not different between the 2 groups. Conclusion Treatment of displaced intraarticular calcaneal fractures with minimally invasive reduction and fixation using either cannulated screws or K-wires can achieve similar excellent functional and radiological outcomes, with high patient satisfaction. The use of K-wires has the advantage of reduced operative time than cannulated screws. Levels of Evidence: Level III: Retrospective comparative study
