Implant failure following pedicle based dynamic stabilization of the lumbar spine.

Acta Orthop Belg 2021 Mar;87(1):191-196

Pedicle-based dynamic stabilization (PBDS) devices such as Dynesys are promoted as an alternative and less invasive option for rigid stabilization of one and even more levels of the lumbar spine. Promising features of the Dynesys system, as well as shortcomings, became obvious in several clinical studies. Since 2012, we started using a new PBDS device as an alternative for the Dynesys, to avoid the screw loosening and the kyphosing effect. Read More

Expandable Cage Technology-Transforaminal, Anterior, and Lateral Lumbar Interbody Fusion.

Oper Neurosurg (Hagerstown) 2021 Jun;21(Supplement_1):S69-S80

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

This review of the literature will focus on the indications, surgical techniques, and outcomes for expandable transforaminal lumbar interbody fusion (TLIF), anterior lumbar interbody fusion (ALIF), and lateral lumbar interbody fusion (LLIF) operations. The expandable TLIF cage has become a workhorse for common degenerative pathology, whereas expandable ALIF cages carry the promise of greater lordotic correction while evading the diseased posterior elements. Expandable LLIF cages call upon minimally invasive techniques for a retroperitoneal, transpsoas approach to the disc space, obviating the need for an access surgeon and decreasing risk of injury to the critical neurovascular structures.

[Electrodiagnosis of Lumbar Spine Disorders and Cauda Equina Syndrome].

Authors:
Masahiro Sonoo

Brain Nerve 2021 Jun;73(6):715-724

Department of Neurology, Teikyo University School of Medicine.

Magnetic resonance imaging (MRI) is widely employed in the diagnosis of lumbar spine disorders, such as lumbar spinal stenosis or lumbar disc herniation. However, incomplete specificity is a definite drawback, given that MRI abnormalities are frequently identified in aged control subjects. Relying solely on MRI without considering clinical symptoms/signs or electrodiagnosis may lead to misdiagnosis. Read More

Biportal endoscopic posterior lumbar decompression and vertebroplasty for extremely elderly patients affected by lower lumbar delayed vertebral collapse with lumbosacral radiculopathy.

J Orthop Surg Res 2021 Jun 14;16(1):380. Epub 2021 Jun 14.

Department of Orthopedic Surgery, Spine Center, Kangnam Sacred Heart Hospital, Hallym University College of Medicine, 1, Singil-ro, Yeongdeungpo-gu, Seoul, Republic of Korea, 07441.

Background: Lower lumbar osteoporotic vertebral compression fracture in extremely elderly patients can often lead to lumbosacral radiculopathy (LSR) due to delayed vertebral collapse (DVC). Surgical intervention requires posterior instrumented lumbar fusion as well as vertebral augmentation or anterior column reconstruction depending on the cleft formation and intravertebral instability. However, it is necessary to decide on surgery in consideration of the patient's frail status, surgical invasiveness, and rehabilitation. Read More

A Current Update on Pelvifemoral Conditions That Should be in the Differential Diagnosis for Patients With Lower Extremity Radiculopathy.

Clin Spine Surg 2021 Jun 14. Epub 2021 Jun 14.

Department of Orthopedic Surgery, Northwestern Memorial Hospital, Chicago, IL Hospital for Special Surgery, New York, NY.

Patients presenting to an outpatient spine clinic frequently report symptoms of low back pain with associated buttock, groin, and lower extremity pain. While many of these individuals suffer from lumbar spine radiculopathy, a number of different orthopedic pathologies can mimic these symptoms. Management depends substantially on a detailed history and physical examination, in addition to working from a broad list of differential diagnoses when evaluating these patients. Read More

Effects of lumbar lordosis increment on gait deteriorations in ambulant boys with Duchenne Muscular Dystrophy: A cross-sectional study.

Braz J Phys Ther 2021 May 24. Epub 2021 May 24.

Antalya Training and Research Hospital, Department of Neurology, Health Sciences University, Antalya, Turkey; Antalya Training and Research Hospital, Neuromuscular Disease Center, Health Sciences University, Antalya, Turkey.

Background: Increment of lumbar lordosis, a frequent spinal finding in Duchenne Muscular Dystrophy (DMD), is a compensatory mechanism secondary to muscle weakness. However, excessive lumbar lordosis may change the position of the center of mass, and lead to balance and walking difficulties.

Objective: To study the relationship between factors that may influence ambulatory function in boys with DMD and to investigate the effects of lumbar lordosis increment on gait and balance perturbations. Read More
