Assessment of the lower limb biomechanics in patients after tibiofibular syndesmosis injury treatment
2021
Purpose: There is no consensus as to the number of bone cortices engaged in tibiofibular syndesmosis treatment. The purpose of our study was to assess the weight distribution on the lower limbs after tricortical or quadricortical syndesmosis fixation and different timing of screw removal. Methods: A total of 55 patients who underwent treatment for acute tibiofibular syndesmosis injury were analyzed in this study. The Zebris pedobarographic platform was used to measure the distribution of body weight on the lower limbs. The study population was stratified by the time to syndesmotic screw removal (8–15 weeks versus 16–22 weeks) and the number of bone cortices involved in fixation (three [tric…
Anatomia e biomeccanica del posterolateral corner del ginocchio
2009
“Dark side of the knee”: letteralmente, lato oscuro del ginocchio. Questa definizione ben si adatta alle strutture postero-esterne del ginocchio. Questa regione anatomica negli ultimi anni ha saputo attirare l’attenzione di ricercatori e studiosi, per molto e forse troppo tempo focalizzata sullo studio del legamento crociato anteriore. Comunque, l’analisi dei risultati e degli insuccessi della chirurgia ricostruttiva del legamento crociato anteriore ha dato uno slancio fondamentale per comprendere ancor di più la complessa biomeccanica del ginocchio e le lesioni associate a rottura dei legamenti del pivot centrale come quelle postero-laterali. In questa rivisitazione della letteratura ci si…
Radiographic Assessment of Tibiofibular Syndesmosis Injury with Different Durations and Types of Fixation
2022
Introduction: There is no consensus among orthopedic surgeons on the number of cortical layers (tricortical or quadricortical fixation) involved or the duration of syndesmotic fixation after a tibiofibular syndesmosis (TFSD)-injury treatment. The purpose of this study was to assess radiographic parameters following the treatment of TFSD injuries, with various time-windows of syndesmotic screw removal and numbers of cortical layers involved. Materials and Methods: Fifty-five patients, aged from 25 to 75 years, were included in the study. The follow-up period ranged from 2 years to 4 years and 2 months. The patients were subdivided into groups based on the duration of the syndesmotic fixation…
Mandibular odontogenic myxoma : reconstructive considerations by means of the vascularized fibular free flap
2006
The odontogenic myxoma is a rare entity located in mandible and upper maxilla. Due to its local aggressiveness, wide surgical excision is mandatory. Several surgical techniques have been described for the reconstruction of segmental mandibular defects. In comparison with other free flaps, the vascularized free fibular flap (VFFF) supports the longest amount of bone and, due to the nature of the vascular supply a complete freedom in location of the osteotomy is present. A precise mandibular arc can be performed following bone resection. We suggest the performance of the ?in situ? VFFF technique in order to recreate mandibular contour by means of several osteotomies, while the pedicle is stil…
