Antegrade Posterior Column Acetabulum Fracture Screw Fixation via Posterior Approach: A Biomechanical Comparative Study [PDF]

Medicina, 2023
Background and Objectives: Minimally invasive surgeries for acetabulum fracture fixation are gaining popularity due to their known advantages versus open reduction and internal fixation.

Experimental ex vivo characterization of the biomechanical effects of laminectomy and posterior fixation of the lumbo-sacral spine [PDF]

Scientific Reports
Laminectomy and posterior fixation are well-established surgical techniques to decompress nervous structures in case of lumbar spinal stenosis. While laminectomy is suspected to increase the instability of the spine, posterior fixation is associated with

Efficacy and safety of lateral lumbar interbody fusion for lumbar degenerative diseases with or without auxiliary posterior fixation: a meta-analysis and systematic review [PDF]

BMC Musculoskeletal Disorders
Background There is no conclusive evidence from evidence-based medicine that clarifies whether the efficacy and safety of lateral lumbar interbody fusion (LLIF) differ significantly with or without auxiliary posterior fixation.

Defining a Safe Zone for Percutaneous Screw Fixation of Posterior Malleolar Fractures

, 2021
Posterior malleolar fractures require fixation to confer stability to the ankle. Although some have suggested that fractures involving less than 25% of the articular surface require no intervention, estimation of malleolar size on plain imaging is ...

Lateral rectus posterior fixation suture [PDF]

Journal of American Association for Pediatric Ophthalmology and Strabismus, 2010
Some authors have suggested that a posterior fixation suture on the lateral rectus muscle is ineffective because of the muscle's long arc of contact with the globe. We report a small case series of patients successfully treated using a lateral rectus posterior fixation suture.The surgical database of one surgeon (JMH) was reviewed for all patients ...

Influence of posterior pedicle screw fixation at L4–L5 level on biomechanics of the lumbar spine with and without fusion: a finite element method

BioMedical Engineering OnLine, 2021
Background Posterior pedicle screw (PS) fixation, a common treatment method for widespread low-back pain problems, has many uncertain aspects including stress concentration levels, effects on adjacent segments, and relationships with physiological ...

Comparison of the efficacy of posterior-anterior screws, anterior-posterior screws and a posterior-anterior plate in the fixation of posterior malleolar fractures with a fragment size of ≥ 15 and < 15%

BMC Musculoskeletal Disorders, 2020
Background Different fixation methods have been used to treat posterior malleolar fractures (PMFs), but the clinical efficacy of different fixation methods in the treatment of PMF with different fragmentation has rarely been reported. The purpose of this

The posterior superior iliac rim screw as an adjunct to pelvic fixation in complex spinopelvic stabilization

North American Spine Society Journal, 2021
Background: Fixation to the ilium is a commonly used alternative or supplement to sacral fixation in complex spinopelvic reconstructions. This can be achieved with traditional posterior superior iliac spine or S2 alar-iliac screws.
