ABSTRACT: Atypical subtrochanteric and diaphyseal femoral fractures (AFF) have been suggested to be associated with the use of bisphosphonates (BPs), but the role of these drugs is still under debate. A 64-year old female, never treated with BPs was admitted to our Rehabilitation Institute because of a recent right AFF. The patient began suffering from low back pain radiating to the groin and to the anterior regions of the right thigh and leg, A nuclear magnetic resonance (NMR) of the lumbar spine showed disc protrusions at the L3-L4 and L5-S1 levels with impingement of the spinal nerve root...

OBJECTIVE: The purpose of this commentary is to provide an argument for the role and identity of chiropractors as spine care providers within the context of the greater health care system. DISCUSSION: Surveys of the general public and chiropractors indicate that the majority of patients seek chiropractic services for back and neck pain. Insurance company utilization data confirm these findings. Regulatory and legal language found in chiropractic practice acts reveals that most jurisdictions define the chiropractic scope of practice as based on a foundation of spine care...

PURPOSE: Debate remains whether posterior implants after thoracolumbar spine fracture stabilization should be removed routinely or only in symptomatic cases. Implant related problems might be resolved or even prevented but removal includes secondary risks. The aim of this study was to evaluate safety, patient satisfaction and quality of life after implant removal. METHODS: A retrospective cohort study was performed concerning 102 patients that underwent posterior implant removal after stabilization of a traumatic thoracolumbar fracture between 2003 and 2015...

BACKGROUND: The historical view of scoliosis as a primary rotation deformity led to debate about the pathomechanic role of paravertebral muscles; particularly multifidus, thought by some to be scoliogenic, counteracting, uncertain, or unimportant. Here, we address lateral lumbar curves (LLC) and suggest a pathomechanic role for quadrates lumborum, (QL) in the light of a new finding, namely of 12th rib bilateral length asymmetry associated with idiopathic and small non-scoliosis LLC. METHODS: Group 1: The postero-anterior spinal radiographs of 14 children (girls 9, boys 5) aged 9-18, median age 13 years, with right lumbar idiopathic scoliosis (IS) and right LLC less that 10°, were studied...

BACKGROUND: Clinicians who assess and treat patients for scoliosis typically use parameters that are all visible from the posterior view. Radiographs assess the internal spinal deformity, but do not directly evaluate body shape, either posterior or anterior. This is problematic, as the patient is most concerned about the way they appear in the mirror. An objective set of anterior measurements is needed to help quantify the anterior asymmetry that is present in scoliosis. METHODS: The design of this system of assessment was developed as a consensus of thinking from four points of view...

STUDY DESIGN: A systematic review and meta-analysis OBJECTIVE.: To investigate the outcomes of anterior lumber interbody fusion (ALIF) with and without an "access surgeon". SUMMARY OF BACKGROUND DATA: Anterior approaches for spine operations have become increasingly popular but may often involve unfamiliar anatomy and territory for spine surgeons, potentially placing the patient at risk to a greater proportion of approach-related complications. Thus many spine surgeons require or prefer the assistance of an "access surgeon" to perform the exposure...

BACKGROUND: Pre-donation of autologous blood prior to spine fusion for adolescent idiopathic scoliosis (AIS) has been used in deformity surgery. The effect of pre-donation on pre-operative hematocrit (Hct) remains debated. Multiple factors may influence pre-operative Hct including intravascular volume status, patient factors, and timing of pre-operative blood donation. The purpose of this study was to determine if pre-donation significantly lowers pre-incision Hct in AIS patients. METHODS: A retrospective cohort study of a Level-1 prospective randomized trial was conducted...

INTRODUCTION: High intensity zones (HIZ) of the lumbar spine are a phenotype of the intervertebral disc noted on MRI whose clinical relevance has been debated. Traditionally, T2-weighted (T2W) magnetic resonance imaging (MRI) has been utilized to identify HIZ of lumbar discs. However, controversy exists with regards to HIZ morphology, topography, and association with other MRI spinal phenotypes. Moreover, classification of HIZ has not been thoroughly defined in the past and the use of additional imaging parameters (e...

Cervical spine trauma in the athlete is not an insignificant occurrence with possibly catastrophic results. Football remains one of the most common and most well studied sporting activities associated with spine injuries. Transient spinal cord and peripheral nerve injuries may manifest as quadriparesis or burners/stingers with symptoms that resolve completely. More severe spinal cord injuries, typically from axial loading on the cervical spine, will cause bilateral symptoms with residual neurological deficit...

The capacity of the nervous system to generate neuronal networks relies on the establishment and maintenance of synaptic contacts. Synapses are composed of functionally different presynaptic and postsynaptic compartments. An appropriate synaptic architecture is required to provide the structural basis that supports synaptic transmission, a process involving changes in cytoskeletal dynamics. Actin microfilaments are the main cytoskeletal components present at both presynaptic and postsynaptic terminals in glutamatergic synapses...

INTRODUCTION: Spinal cord injury (SCI) is a devastating condition with very few treatment options. Surgical decompression of the spine after injury has been shown to improve outcomes; however, the optimal timing of surgery is a matter of debate. METHODS: We collected data from 78 patients with SCI. Based on the time to surgical decompression, we grouped patients into an ultra-early group (decompression within 12 hours of presentation), an early group (within 12-24 hours), and a late group (>24 hours)...

Just as the prevalence of scoliosis began to decline precipitously after World War II, American orthopedic surgeon Dr. Paul R. Harrington devised a new, invasive surgical system whereby implantable prosthetic metal rods and hooks were used to straighten curved backs. By the 1970s, "Harrington rods" had become the gold standard of surgical scoliosis care in the United States, replacing more conventional methods of exercise, bracing, and casting. This article situates the success of Harrington rods within a much larger and historically longer debate about why, when compared to those in other nations, American surgeons appear to be "more aggressive" and "knife-happy...
