Jokeit M, Cornaz F, Schader J, Harshbarger C, Calek A, Jecklin S, et al.
Eur Spine J
. 2025 Feb;
PMID: 39912946
Background: During full flexion of the spine, the paraspinal muscles are largely inactive. This suggests that passive structures like the posterior osteoligamentous complex (POLC), consisting of interspinous and supraspinous ligaments...

Spine Deform
. 2024 Oct;
13(2):423-431.
PMID: 39443425
Introduction: Accurate landmark detection is essential for precise analysis of anatomical structures, supporting diagnosis, treatment planning, and monitoring in patients with spinal deformities. Conventional methods rely on laborious landmark identification...

Tsagkaris C, Fasser M, Farshad M, Passaplan C, Cornaz F, Widmer J, et al.
Spine J
. 2024 Oct;
25(2):380-388.
PMID: 39357743
Background Context: Pedicle screw instrumentation is widely used in spine surgery. Axial screw misplacement is a common complication. In addition to the recognized neurovascular risks associated with screw misplacement, the...

Eur Spine J
. 2024 May;
33(7):2621-2629.
PMID: 38733400
Purpose: To analyze the effect of endplate weakness prior to PLIF or TLIF cage implantation and compare it to the opposite intact endplate of the same vertebral body. In addition,...

Calek A, Cornaz F, Suter M, Fasser M, Baumgartner S, Sager P, et al.
Spine J
. 2023 Nov;
24(5):889-898.
PMID: 37924848
Background Context: Posterior and transforaminal lumbar interbody fusion (PLIF, TLIF) are well-established procedures for spinal fusion. However, little is known about load sharing between cage, dorsal construct, and biological tissue...

J Arthroplasty
. 2023 Jun;
39(1):145-150.
PMID: 37331442
Background: Component malposition in total hip arthroplasty (THA) can lead to dislocation, early implant failure, and revision surgery. As the surgical approach might affect the targeted combined anteversion (CA) of...

Haupt S, Cornaz F, Falkowski A, Farshad M, Widmer J
J Biomech
. 2023 May;
153:111599.
PMID: 37137272
In the flexed end-of-range position (e.g., during slumped sitting), the trunk is passively stabilized. Little is known about the biomechanical consequence of posterior approaches on passive stabilization. The aim of...

Burkhard M, Calek A, Fasser M, Cornaz F, Widmer J, Spirig J, et al.
Eur Spine J
. 2023 Apr;
32(6):1876-1886.
PMID: 37093262
Purpose: The aim of this study was to elucidate segmental range of motion (ROM) before and after common decompression and fusion procedures on the lumbar spine. Methods: ROM of fourteen...

JOR Spine
. 2023 Mar;
6(1):e1237.
PMID: 36994463
Background: Vertebral endplate signal intensity changes visualized by magnetic resonance imaging termed Modic changes (MC) are highly prevalent in low back pain patients. Interconvertibility between the three MC subtypes (MC1,...

Eur Spine J
. 2023 Mar;
32(5):1695-1703.
PMID: 36930387
Purpose: To develop ligamentous vertebral stabilization techniques ("vertebropexy") that can be used after microsurgical decompression (intact posterior structures) and midline decompression (removed posterior structures) and to elaborate their biomechanical characteristics....
