Pars interarticularis injury in elite athletes - The role of imaging in diagnosis and management.

Eur J Radiol 2018 Nov 1;108:28-42. Epub 2018 Sep 1.

Fortius Clinic, 17 Fitzhardinghe Street, London W1H 6EQ, United Kingdom. Electronic address:

Injuries of the lumbar neural arch, in particular the pars interarticularis, are widely considered to be due to abnormal bone stress secondary to repetitive loading/shearing, and are a common pathology and a main cause of lower back pain in elite athletes across a range of sports. Medical imaging plays a pivotal role in the diagnosis, monitoring and prognostication of neural arch injury. Early detection is highly desirable in the young elite athlete, as early injuries have been shown to require shorter recovery time and have a higher potential of full healing, whilst accurate grading of injury allows appropriate rehabilitation planning.

Spondylolisthesis and tumors: a treatment algorithm.

Eur Spine J 2018 06 13;27(Suppl 2):206-212. Epub 2018 Apr 13.

IRCCS Galeazzi Orthopedic Institute, Milan, Italy.

Background: Pars defect and spondylolisthesis are frequent conditions, while bone tumors-particularly the primaries-are rare. The contemporary occurrence can delay the diagnosis of the tumor, if symptoms are considered related to spondylolisthesis, or can make reconstruction more demanding. To our knowledge, only two case reports of this contemporary occurrence have been published in the literature. Read More

Mild (not severe) disc degeneration is implicated in the progression of bilateral L5 spondylolysis to spondylolisthesis.

BMC Musculoskelet Disord 2018 04 2;19(1):98. Epub 2018 Apr 2.

Spine Service, Department of Orthopaedic Surgery, St. George & Sutherland Clinical School, University of New South Wales Australia, Kogarah, Sydney, NSW, 2217, Australia.

Background: Spondylolytic (or lytic) spondylolisthesis is often associated with disc degeneration at the index-level; however, it is not clear if disc degeneration is the cause or the consequence of lytic spondylolisthesis. The main objective of this computed tomography based finite element modelling study was to examine the role of different grades of disc degeneration in the progression of a bilateral L5-lytic defect to spondylolisthesis.

Methods: High-resolution computed tomography data of the lumbosacral spine from an anonymised healthy male subject (26 years old) were segmented to build a 3D-computational model of an INTACT L1-S1 spine. Read More

Acquired spondylolysis and spinopelvic sagittal alignment.

Eur J Orthop Surg Traumatol 2018 Aug 22;28(6):1033-1038. Epub 2018 Mar 22.

Spine Center Stuttgart, Paulinenhilfe, Diakonie-Klinikum Stuttgart, 38 Rosenbergstrasse, 70176, Stuttgart, Germany.

Acquired spondylolysis represents an uncommon complication of spine surgery, of an unknown incidence and etiology. We studied patients presenting this rare entity, with the purpose to investigate the incidence, imaging findings, patients' clinical characteristics, as well as to provide an interpretation of the mechanisms that may lead to this phenomenon. The presented working hypothesis, regarding etiology, suggests that there is a relation between variations in spinopelvic sagittal alignment and acquired spondylolysis. Read More

ISSLS PRIZE IN BIOENGINEERING SCIENCE 2018: dynamic imaging of degenerative spondylolisthesis reveals mid-range dynamic lumbar instability not evident on static clinical radiographs.

Eur Spine J 2018 04 22;27(4):752-762. Epub 2018 Feb 22.

Department of Orthopaedic Surgery, Orthopaedic Biodynamics Laboratory, University of Pittsburgh, 3820 South Water Street, Pittsburgh, PA, 15203, USA.

Purpose: Degenerative spondylolisthesis (DS) in the setting of symptomatic lumbar spinal stenosis is commonly treated with spinal fusion in addition to decompression with laminectomy. However, recent studies have shown similar clinical outcomes after decompression alone, suggesting that a subset of DS patients may not require spinal fusion. Identification of dynamic instability could prove useful for predicting which patients are at higher risk of post-laminectomy destabilization necessitating fusion. Read More

Traumatic Atlantoaxial Spondyloptosis Associated with Displaced Odontoid Fracture: Complete Reduction via Posterior Approach Using "Joint Remodeling" Technique.

World Neurosurg 2018 Feb;110:609-613

Department of Neurosurgery, All India Institute of Medical Sciences and Jai Prakash Narayan Apex Trauma Centre, New Delhi, India.

Background: Atlantoaxial spondyloptosis (AAS), which is defined as complete displacement of facets of atlas anterior to the facets of axis such that there is no contact between the 2 articulating surfaces, is an extremely rare manifestation of atlantoaxial instability. The reason for an extreme rarity of traumatic AAS is probably the severity of injury in traumatic AAS that is usually incompatible to life. It represents the most severe form of atlantoaxial dislocation, and complete reduction in such a case presents a real technical challenge because of the interlocking of C1-C2 facets. Read More
