    L\u2019analisi vuole far luce su alcuni aspetti e comportamenti delle imprese piemontesi iscritte all\u2019Albo Artigiani della Camera di Commercio. In particolare, si cerca di incominciare ad indagare e descrivere il fenomeno dell\u2019evasione contributiva e le sue relazioni con alcune caratteristiche osservabili delle aziende e, tra queste, gli eventuali finanziamenti ricevuti sugli specifici capitoli di sostegno all\u2019artigianato. A tale scopo vengono utilizzate le informazioni provenienti dagli archivi della vigilanza ispettiva INPS Piemonte, in cui sono riportati i risultati delle ispezioni effettuate dall\u2019Istituto negli anni 2000-2005, collegate con quelle contenute nella banca dati dell\u2019Osservatorio dell\u2019Artigianato. Lo scopo principale del progetto \ue8 mostrare la validit\ue0 del linkage tra i diversi archivi e le potenzialit\ue0 delle analisi che se ne possono trarre, mettendo in evidenza risultati utilizzabili per la valutazione delle politiche pubbliche

    Segond's fracture: a biomechanical cadaveric study using navigation

    Background Segond’s fracture is a well-recognised radiological sign of an anterior cruciate ligament (ACL) tear. While previous studies evaluated the role of the anterolateral ligament (ALL) and complex injuries on rotational stability of the knee, there are no studies on the biomechanical effect of Segond’s fracture in an ACL deficient knee. The aim of this study was to evaluate the effect of a Segond’s fracture on knee rotation stability as evaluated by a navigation system in an ACL deficient knee. Materials and methods Three different conditions were tested on seven knee specimens: intact knee, ACL deficient knee and ACL deficient knee with Segond’s fracture. Static and dynamic measurements of anterior tibial translation (ATT) and axial tibial rotation (ATR) were recorded by the navigation system (2.2 OrthoPilot ACL navigation system B. Braun Aesculap, Tuttlingen, Germany). Results Static measurements at 30 showed that the mean ATT at 30 of knee flexion was 5.1 ± 2.7 mm in the ACL intact condition, 14.3 ± 3.1 mm after ACL cut (P = 0.005), and 15.2 ± 3.6 mm after Segond’s fracture (P = 0.08). The mean ATR at 30 of knee flexion was 20.7 ± 4.8 in the ACL intact condition, 26.9 ± 4.1 in the ACL deficient knee (P[0.05) and 30.9 ± 3.8 after Segond’s fracture (P = 0.005). Dynamic measurements during the pivot-shift showed that the mean ATT was 7.2 ± 2.7 mm in the intact knee, 9.1 ± 3.3 mm in the ACL deficient knee(P = 0.04) and 9.7 ± 4.3 mm in the ACL deficient knee with Segond’s fracture (P = 0.07). The mean ATR was 9.6 ± 1.8 in the intact knee, 12.3 ± 2.3 in the ACL deficient knee (P[0.05) and 19.1 ± 3.1 in the ACL deficient knee with Segond’s lesion (P = 0.016). Conclusion An isolated lesion of the ACL only affects ATT during static and dynamic measurements, while the addition of Segond’s fracture has a significant effect on ATR in both static and dynamic execution of the pivot-shift test, as evaluated with the aid of navigation
