BONE RECONSTRUCTION IN THE TREATMENT OF TIBIAL HEMIMELIA: AN ALTERNATIVE TO AMPUTATION?

Objective: To evaluate the advantages and disadvantages of bone reconstruction and lengthening compared to amputation in the treatment of tibial hemimelia for patients and their families.

Methods: Systematic review of articles published in English and Portuguese between 1982 and 2022 in the MEDLINE, PubMed, Cochrane and SciELO databases. The variables of interest were: year of publication, sample characteristics, classification of tibial hemimelia according to Jones, treatment outcome and follow-up time.

Comparison of sacroiliac screw techniques for unstable sacroiliac joint disruptions: a finite element model analysis.

Vertically unstable pelvic injuries associated with sacroiliac disruption are challenging. Although percutaneous iliosacral fixation using two screws at S1 vertebral body has been shown beneficial, the use of two transiliac screws at S1 has been proposed to increase the fixation strength of the construct. In the herein study, the finite element method (FEM) was performed to analyse the biomechanical behaviour of five different constructions using iliosacral screws only, transiliac screws only, and combining an iliosacral and a transiliac screw.
