Implications of cage impactions in single-level OLIF treatment of degenerative spondylolisthesis.

Introduction: Cage impactions (CI) of Oblique Lumbar Interbody Fusion (OLIF) appear to be a frequent mechanical complication with a potential functional impact.

Objectives: To determine the rate of CI occurrence, their risk factors and clinical implications in the case of combined single-level arthrodesis.

Method: A retrospective analysis of prospectively collected data was performed.

Posterior hinge fixation for the treatment of unstable traumatic sacroiliac joint injuries.

Introduction: Posterior hinge fixation (PHF) is a sacroiliac joint fixation method indicated for the surgical treatment of unstable pelvic ring fractures (tile C).

Hypothesis: PHF yields good functional outcomes based on the Majeed score at more than 1 year of follow-up.

Methods: A single-center, retrospective study of patients who had a Tile C pelvic ring fracture, who were operated by PHF and who were evaluated at a minimum follow-up of 1 year.

Minimally invasive unilateral lumbar interbody fusion (UNILIF) in over-80-year-olds. Continuous series of 42 patients at 1.4 years' follow-up.

Introduction: In lumbar stenosis, surgery aims to improve quality of life in increasingly elderly patients. Minimally invasive techniques better suit the requirements of elderly patients with increasing functional demand.

Hypothesis: The UNILIF unilateral lumbar interbody fusion technique improves functional scores at 1 year in over-80 year-olds, with low morbidity.
