Mariuccia Salvati dedicates the last chapter of volume to “almost” two lives Camillo Pellizzi, first characterized by militant adherence fascism, second “pure” study society. This article mainly deals with this phase, phase maturity, which coincides decades post-war period. The role sociologist played in many ways original and innovative, was however not always recognized appreciated Italian so...

The purpose of this study was to determine whether distraction osteogenesis can be used to treat hypertrophic nonunion associated with angular deformity and shortening after Coventry style high tibial osteotomy. Five consecutive patients were retrospectively reviewed. In all patients the alignment had collapsed into excessive varus or valgus and leg length discrepancy was present. The leg lengt...

PURPOSE The purpose of this study was to document results of a less invasive technique of open wedge proximal tibial osteotomy (PTO) for the varus knee in young adults using an intramedullary tibial nail. MATERIALS AND METHODS We prospectively studied 24 knees in 16 young patients with varus knee deformity. The mean follow-up was 54 months (range, 36 to 107 months) and the mean age of patient...

BACKGROUND Patella alta and patella baja are important conditions underlying a predisposition to many joint diseases, including patellar luxation and patellar chondromalacia of the articular cartilage. The frequencies of patella alta and patella baja have not yet been determined. The objectives of this study were to determine the frequency of patella alta and to determine reference values to th...

The aim of this study was to analyze clinical and radiologic results of an arthroscopic medial plication with the pullout technique and to define indications and limitations of this procedure for patellar instability. Records of 45 patients treated for patellar instability with arthroscopic medial plication with the pullout technique were reviewed. The mean patient age was 22.8±8.3 years. The t...

The purpose of this study is to determine if patellar maltracking is more prevalent among patellofemoral (PF) pain subjects with patella alta compared to subjects with normal patella height. We imaged 37 PF pain and 15 pain free subjects in an open-configuration magnetic resonance imaging scanner while they stood in a weightbearing posture. We measured patella height using the Caton-Deschamps, ...

The authors have retrospectively studied the results achieved with the AO/ASIF PFN system in the treatment of unstable intertrochanteric fractures of the proximal femur. Between June 1999 and February 2003, 51 patients with unstable intertrochanteric fractures of the proximal femur underwent intramedullary nailing with the PFN system. A total of 45 patients (28 women, 17 men, average age 72 yea...

Background: Recurrent patellar dislocation (RPD) and habitual (HPD) in flexion are frequently encountered children adolescents. Purpose: To compare the radiological features of RPD HPD Study Design: Cross-sectional study; Level evidence, 3. Methods: Imaging data were collected from patients aged 9 to 15 years who received surgical treatment for or at a single institution between June 2015 Septe...

Abstract. In this note we study the geometry of principally polarized abelian varieties (ppavs) with a vanishing theta-null (i.e. with a singular point of order two and even multiplicity lying on the theta divisor) — denote θnull the locus of such ppavs. We describe the locus θ null ⊂ θnull where this singularity is not an ordinary double point. By using theta function methods we first show θ n...
