A clinical and biomechanical comparison of INFIX plus single versus double sacroiliac screw fixation for unstable pelvic ring injury.

Background: The aim of this study is to compare the clinical and biomechanical outcome of INFIX plus single with two sacroiliac screw fixation for unstable pelvic fractures of Type C.

Methods: Sixteen cadavers were randomly subjected to INFIX plus single or double sacroiliac screw fixations and then mounted onto the ElectroForce loading machine under different vertical loads. To investigate the clinical outcomes of the two techniques, nineteen patients were retrospectively analyzed.

[Imaging evaluations of Salter innominate osteotomy for developmental dysplasia of the hip].

Objective: To evaluate the imaging efficacies after Salter innominate osteotomy for developmental dysplasia of the hip (DDH).

Methods: A total of 51 DDH patients with 70 hips were recruited between March 2011 to August 2012. All of them underwent Salter innominate osteotomy.
