OBJECTIVE To correlate spinopelvic balance with the development of degenerative spondylolisthesis and disk herniation. METHODS This was a descriptive retrospective study that evaluated 60 patients in this hospital, 30 patients with degenerative spondylolisthesis at the L4-L5 level and 30 with herniated disk at the L4-L5 level, all of whom underwent Surgical treatment. RESULTS Patients with ...

Objective. To propose and validate a dimensional parameter, the sagittal pelvic thickness (SPT) (distance between the middle point of the upper sacral plate and the femoral heads axis, expressed as a ratio with the length of the upper plate of S1: (SPT/S1) for the analysis of the sagittal balance of the pelvispinal unit. Methods. The parameters were analysed on standing radiographic imaging and...

Percutaneous iliosacral screws are useful in treating vertical posterior pelvic fractures and iliosacral disruptions. Iliosacral screws are far less invasive than spinopelvic fixation, and result in much lower morbidity. However, safe placement of the iliosacral screws is technically difficult and highly dependent on fracture reduction and adequate fluoroscopy. Inaccurate placement can result i...
