Ligamentum Flavum Buckling vs Hypertrophy in Cervical Myelopathy Using Dynamic Imaging: Are Instability and Loss of Disc Height the Culprits?

Int J Spine Surg 2022 Apr;16(2):300-308

Department of Spine Service, Indian Spinal Injuries Center, Vasant Kunj, New Delhi, Delhi 110070, India.

Background: The literature has not distinguished between LF "hypertrophy" and "buckling" when addressing cervical spondylotic myelopathy. The identification of buckling on dynamic magnetic resonance imaging can determine the levels for decompression more accurately and modify the surgical plan accordingly. No studies have been performed in the cervical spine to analyze the factors affecting LF buckling. Read More

Examining the protective role of the posterior elements of the spine against endplate fractures in a porcine model.

Eur Spine J 2022 Jun 4;31(6):1501-1507. Epub 2022 Apr 4.

Department of Kinesiology and Physical Education, Wilfrid Laurier University, Waterloo, ON, Canada.

Previous studies have shown that the posterior elements/facet joints provide strength to the overall functional spine unit (FSU) by taking 3-25% of vertical compressive load off the intervertebral disc (IVD). However, little is known regarding whether this offloading has a protective effect against endplate fracture. Therefore, the purpose of this study was to investigate if the posterior elements provide a protective role to the endplate in porcine cervical spines under fracture-inducing conditions. Read More

Acromioclavicular joint instability on cross-body adduction view: the biomechanical effect of acromioclavicular and coracoclavicular ligaments sectioning.

BMC Musculoskelet Disord 2022 Mar 23;23(1):279. Epub 2022 Mar 23.

Department of Orthopedic Surgery, Nara Medical University, 840 Shijoutyou, Kashihara City, Nara, 634-5821, Japan.

Background: The acromioclavicular (AC) and coracoclavicular (CC) ligaments are important stabilizers of the AC joint. We hypothesized that AC and trapezoid ligament injuries induce AC joint instability and that the clavicle can override the acromion on cross-body adduction view even in the absence of conoid ligament injury. Accordingly, we investigated how sectioning the AC and CC ligaments contribute to AC joint instability in the cross-body adduction position. Read More

High Volume PRP Therapy.

Authors:
Piotr Godek

Ortop Traumatol Rehabil 2022 Feb;24(1):43-60

Sutherland Medical Center, Warszawa, Polska / Sutherland Medical Center, Warsaw, Poland.

Background: The PRP method is widely used to support healing and regeneration in musculoskeletal and aesthetic medicine. The current literature, however, brings contradictory reports as to its effectiveness, which, at least in part, should be attributed to the diversity of methods for producing the concentrate, including the use of various volumes of whole blood, single vs double centrifugation vs filtration, use of thrombin vs calcium chloride to activate the process, and, finally, the use of an anticoagulant. The aim of the study was to retrospectively evaluate the effectiveness of high-volume PRP therapy with the Angel® system (Arthrex) in our patients. Read More

Delayed Treatment of Traumatic Cervical Dislocation: A Case Report and Literature Review.

Case Rep Orthop 2022 2;2022:7756484. Epub 2022 Mar 2.

Orthopaedic and Trauma Surgery Department, Les Cliniques du Sud-Luxembourg-Vivalia, Arlon, Belgium.

Neglected unreduced cervical dislocation is very uncommon. In our case (a lady who stayed asymptomatic for 13 months before development of cervicobrachialgia), the anterior reduction/arthrodesis was easy, and we did not find any benefit from an additional posterior procedure thanks to a congenital block between C7 and T1 vertebral bodies. This point is nevertheless a matter of debate. Read More

Minimally Invasive Posterior Cervical Discectomy: 2-Dimensional Operative Video.

Oper Neurosurg (Hagerstown) 2021 11;21(6):E536

Department of Neurosurgery, Henry Ford Hospital, Detroit, Michigan, USA.

Minimally invasive posterior cervical microdiscectomy is an appropriate surgical approach for patients with foraminal stenosis from herniated disc with radicular symptoms that is not responsive to conservative management. While anterior cervical discectomy and fusion (ACDF) or arthroplasty is increasingly utilized to treat herniated disc, a posterior approach eliminates the risk of potential approach related injuries to the esophagus, carotid artery, or recurrent laryngeal nerve. Additional benefits of posterior decompression include avoidance of instrumentation, which represents an increased healthcare cost, as well as potential long-term risks of adjacent-level pathologies or device failures.

Association between Condylar Bone Density and Disk Displacement in the Temporomandibular Joint.

J Clin Densitom 2022 Apr-Jun;25(2):215-222. Epub 2021 Jul 24.

Department of Orthodontics and Dental Research Institute, School of Dentistry, Seoul National University, Seoul, Korea. Electronic address:

Measuring bone density (BD) is a common method of determining bone quality; however, the relationship between condylar BD and the occurrence of temporomandibular joint (TMJ) disorders has not been investigated. To address this knowledge gap, we aimed to investigate condylar BD in terms of TMJ disk displacement (TMJ DD) using computed tomography (CT) and magnetic resonance imaging (MRI). We classified TMJ MRI results according to the position of the disk: normal disk position (Normal), anterior disk displacement with reduction (ADDR), and anterior disk displacement without reduction (ADDNR).

Association of neurologic signs with high-field MRI findings in 100 dogs with osseous-associated cervical spondylomyelopathy.

Vet Radiol Ultrasound 2021 Nov 9;62(6):678-686. Epub 2021 Aug 9.

Department of Veterinary Clinical Sciences, College of Veterinary Medicine, The Ohio State University, Columbus, Ohio, USA.

Although osseous-associated cervical spondylomyelopathy (OA-CSM) findings have been well described using magnetic resonance imaging (MRI), there are no large-scale published studies on the associations between dog size, age, high-field MRI and neurologic findings. Using a retrospective, observational study design, we aimed to investigate an association between neurologic and high-field MRI characteristics in OA-CSM. Records were reviewed for dogs diagnosed with OA-CSM using high-field MRI. Read More

Poor Bone Quality, Multilevel Surgery, and Narrow and Tall Cages Are Associated with Intraoperative Endplate Injuries and Late-onset Cage Subsidence in Lateral Lumbar Interbody Fusion: A Systematic Review.

Clin Orthop Relat Res 2022 01;480(1):163-188

Department of Orthopaedics and Traumatology, The University of Hong Kong, Hong Kong SAR, China.

Background: A major complication of lateral lumbar interbody fusion (LLIF) is cage subsidence, which may lead to clinical problems, including loss of disc height correction, altered spinal alignment, recurrent pain, and vertebral body fracture. A thorough review of the current knowledge about the risk factors for the two types of cage subsidence after LLIF-intraoperative endplate injury and late-onset cage subsidence-could bring attention to well-established risk factors for clinical consideration while identifying any incompletely characterized factors that require further research to clarify.

Questions/purposes: We performed a systematic review to answer the following questions: (1) Are bone quality and surrogates for bone quality, such as patient age and sex, associated with an increased likelihood of cage subsidence? (2) Are implant-related factors associated with an increased likelihood of cage subsidence?

Methods: Two independent reviewers comprehensively searched Medline, Embase, Cochrane Library, PubMed, and Web of Science from 1997 to 2020 to identify all potential risk factors for cage subsidence after LLIF. Read More
