Randomized Controlled Trial
BACKGROUND
One proposed mechanism of chronic low back pain might be paraspinal muscle impairment. Commonly, this impairment is treated with stabilization exercises. However, the effect size of stabilization exercises has been previously reported to be small.
DESIGN
Randomized controlled trial.
OBJECTIVE
To investigate the clinical benefit of using neuromuscular electrical stimulation as a supplement to stabilization exercises in patients with chronic low back pain.
METHODS
Thirty participants with chronic low back pain were randomized into a stabilization exercise only group (n=15) or a stabilization exercise plus neuromuscular electrical stimulation group (n=15). The stabilization exercises included abdominal, side support, and quadruped exercises. The neuromuscular electrical stimulation was applied to the lumbar paraspinal muscles for 20min each session. Both groups received their respective interventions twice a week for 6 weeks. Participant eligibility for inclusion was age between 18 and 60 years, body mass index ≤34, chronic low back pain ≥3 months, Numeric Pain Rating Scale ≥3, Modified Oswestry Disability Questionnaire score ≥20 and ability to understand English. Outcome measurements were self-reported neuromuscular electrical stimulation tolerability scale, Modified Oswestry Disability Questionnaire, Numeric Pain Rating Scale, Fear-Avoidance Beliefs Questionnaire and paraspinal muscle strength.
RESULTS
The neuromuscular electrical stimulation was reported to be tolerable. There were no significant between-group differences on any of the outcome measures (p>0.05).
CONCLUSIONS
The application of neuromuscular electrical stimulation on the paraspinal muscles was reported to be tolerable. Supplementing stabilization exercises with neuromuscular electrical stimulation did not offer any additional clinical benefit for the chronic low back pain patients.

Laboratory study using a repeated measures design. The aim of this study was to determine if ankle proprioception is targeted in exercises on unstable surfaces. Lateral ankle sprain (LAS) has recurrence rates over 70%, which are believed to be due to a reduced accuracy of proprioceptive signals from the ankle. Proprioceptive exercises in rehabilitation of LAS mostly consist of balancing activities on an unstable surface. The methods include 100 healthy adults stood barefoot on a solid surface and a foam pad over a force plate, with occluded vision. Mechanical vibration was used to stimulate proprioceptive output of muscle spindles of triceps surae and lumbar paraspinal musculature. Each trial lasted for 60 s; vibration was applied from the 15th till the 30th second. Changes in mean velocity and mean position of the center of pressure (CoP) as a result of muscle vibration were calculated. Results show that on foam, the effect of triceps surae vibration on mean CoP velocity was significantly smaller than on a solid surface, while for paraspinal musculature vibration the effect was bigger on foam than on solid surface. Similar effects were seen for mean CoP displacement as outcome. Exercises on unstable surfaces appear not to target peripheral ankle proprioception. Exercises on an unstable surface may challenge the capacity of the central nervous system to shift the weighting of sources of proprioceptive signals on balance.

Review
PURPOSE
The effect of paraspinal muscles atrophy and fat infiltration (FI) on the complications of spinal surgery has not been established.
METHODS
A review of the literature was conducted from a search of the PubMed, EMBASE, and Web of Science databases from inception through January 2021. The literature was searched and assessed by independent reviewers based on criteria that included an assessment of preoperative paraspinal muscle morphology in addition to measuring its relationship to surgical complications. All relevant papers were assessed for risk of bias according to the modified Newcastle Ottawa Scale and the Joanna Briggs Institute Critical Appraisal Tools. A narrative synthesis was conducted.
RESULTS
The initial search yielded 5632 studies, of which 16 studies were included in the analysis. All included studies were at a low risk of bias. There existed strong evidence that the atrophy and FI of paraspinal muscles had an association with the development of bone nonunion (two high quality studies), pedicle screw loosening (two high quality studies), adjacent segment degeneration (three high quality studies) and proximal junctional kyphosis (five high quality studies) after lumbar surgery. Besides, there is also limited evidence for association between atrophy and FI of paraspinal extensor muscles and less local and global curve improvement.
CONCLUSIONS
Strong evidence was found for an association between preoperative paraspinal muscle degeneration and multiple postoperative complications after lumbar surgery. However, the findings should be interpreted with caution due to the small quantity of the available literature and high heterogeneity among studies.

Composite hemangioendothelioma (CHE) is a very rare, low-grade malignant vascular tumor. It is most commonly seen as one or more nodules on both sides of the fingers and toes. This tumor rarely settles in the paraspinal muscles. The age of onset is usually between 21 and 72 years, with an average age of 39.5-41 years. Treatment is with gross total removal of the lesion. We present a case of a 54-year-old male patient with a 2-year history of low back pain. Lumbar spine magnetic resonance imaging revealed CHE in the right paravertebral muscle in the posterior vicinity of the transverse process between the right paraspinal muscle planes. The entire mass was removed grossly. The definitive diagnosis of CHE was made histopathologically. This is a rare case of CHE that had settled in the paraspinal region.

The paraspinal compartment acts as a bone-muscle composite beam of the spine. The elastic properties of the paraspinal muscles play a critical role in spine stabilization. These properties depend on the subjects' posture, and they may be drastically altered by low back pain. Supersonic shear wave elastography can be used to provide quantitative stiffness maps (elastograms), which characterize the elastic properties of the probed tissue. The aim of this study was to challenge shear wave elastography sensitivity to postural stiffness changes in healthy paraspinal muscles. The stiffness of the main paraspinal muscles (longissimus, iliocostalis, multifidus) was measured by shear wave elastography at the lumbosacral level (L3 and S1) for six static postures performed by volunteers. Passive postures (rest, passive flexion, passive extension) were performed in a first shear wave elastography session, and active postures (upright, bending forward, bending backward) with rest posture for reference were performed in a second session. Measurements were repeated three times for each posture. Sixteen healthy young adults were enrolled in the study. Non-parametric paired tests, multiple analyses of covariance, and intra-class correlations were implemented for analysis. Shear wave elastography showed good to excellent reliability, except in the multifidus at S1, during bending forward, and in the multifidus at L3, during bending backward. Yet, during bending forward, only poor quality was recorded for nine volunteers in the longissimus. Significant intra- and inter-muscular changes were observed with posture. Stiffness significantly increased for the upright position and bending forward with respect to the reference values recorded in passive postures. In conclusion, shear wave elastography allows reliable assessment of the stiffness of the paraspinal muscles except in the multifidus at S1 and longissimus, during bending forward, and in the multifidus at L3, during bending backward. It reveals a different biomechanical behaviour for the multifidus, the longissimus, and the iliocostalis.

BACKGROUND/AIM
Reconstruction of spinal soft tissue defects is challenging, especially when neural structures or prosthetic material are exposed. They should be covered with well-vascularized tissue such as paraspinal perforator flaps.
MATERIALS AND METHODS
This is a retrospective study of soft tissue reconstructions with paraspinal perforator flaps from 2011 to 2018. The technique is described and risk factors for poor wound healing were assessed. Postoperative complications are reported.
RESULTS
Twenty patients with a mean age of 63.65 years were included. Defects had an average size of 47 cm and were mainly located in the lumbosacral region (9 patients). Twelve patients suffered from infection following spinal stabilization, seven of whom were diagnosed with osteomyelitis, two patients presented with pressure sore and one patient experienced wound dehiscence. One partial flap necrosis with a lumbar defect occurred, which required revision surgery. No total flap loss occurred. Stable, closed wounds were achieved at their final follow-up.
CONCLUSION
Perforator paraspinal flaps are suitable for immediate reconstruction of spinal defects.

Review
UNLABELLED
Textilomas, gossypibomas, muslinomas and gauzomas, otherwise collectively known as Retained Non-absorbable Hemostatic Material (RNHM), are surgical materials such as cotton or gauze pads that are accidentally retained in the surgical bed post-operatively. They may present acutely with signs of infection or may rarely remain chronic and asymptomatic; the latter posing a significant challenge to clinical and imaging diagnosis. Textilomas are not routinely reported due to their medicolegal implications and are usually encountered fortuitously. Here, we report a case of an individual who presented with a non-specific lower backache, had a remote history of lumbar discectomy and in whom a textiloma at the postoperative site was seen to mimic a soft-tissue mass on imaging. In addition, we review current, up-to-date literature on delayed presentations of such retained materials after surgery of the lumbar spine.
CASE REPORT
A 43-year-old male presented with pain in his right lower back and gluteal region. He had undergone an L4-L5 discectomy 11 years ago, remained asymptomatic since, and noticed an insidious, worsening pain a week before presentation. Mild tenderness was elicited over the region of pain. A clinical diagnosis of L4-L5 extraforaminal disc prolapse with deep surgical site infection was made. Ultrasound showed an iso-to-hyperechogenic lesion in the right lower paraspinal region. MRI showed a very well-defined, ovoid T1-hypointense and T2-iso-hypointense lesion in the deep posterior paraspinal region of the L4/5 level adjacent to right laminar process of L4 vertebra. The lesion caused scalloping and chronic erosion of the laminar process. No obvious air pockets were present. The features of infection, like soft tissue oedema and collection, were absent. Based on imaging, differentials of nerve sheath tumour and gossipybomas was made. Open wound exploration was performed, which showed a wad of gauze within the right L4-L5 interlaminar space, with thin surrounding granulation tissue The L4-L5 disc and exiting nerve root were normal. The mass was removed, local washing was done and wound was closed.
CONCLUSION
Though unfortunate and relatively rare, the possibility of a textiloma must be considered among the differential diagnoses of a mass in the spinal region in the event of prior surgery, no matter how remote the history. Clinical presentation may vary, but the imaging appearance is largely consistent and can be relied upon to prevent unnecessary investigation and facilitate early surgical removal of the offending retained material.

Review
Traditional surgical techniques for benign intradural and paraspinal nerve sheath tumors often consisted of open posterior approaches. However, these were limited by the morbidity of open surgery. In addition, iatrogenic instability is often required for total resection of larger or laterally located tumors, thus necessitating the use of additional hardware for spinal fusion. Advances in surgical techniques and technologies have allowed for a plethora of minimally invasive approaches throughout the cervical, thoracic, and lumbar regions. These approaches and their particular applications for the resection of benign peripheral nerve sheath tumors are described, with special attention to modern surgical strategies.

Various techniques for regional anesthesia and analgesia of the thorax are currently being used in clinical practice. A recent international consensus has anatomically classified paraspinal blocks in the thoracic spinal region into the following four types: paravertebral, retrolaminar, erector spinae plane, and intertransverse process blocks. These blocks have different anatomical targets; thus, the spreading patterns of the injectates differ and can consequently exhibit different neural blockade characteristics. The paravertebral block directly targets the paravertebral space just outside the neuraxial region and has an analgesic efficacy comparable to that of the epidural block; however, there are multiple potential risks associated with this technique. Retrolaminar and erector spinae plane blocks target the erector spinae plane on the vertebral lamina and transverse process, respectively. In anatomical studies, these two blocks showed different injectate spreading patterns to the back muscles and the fascial plane. In cadaveric studies, paravertebral spread was identified, but variable. However, numerous clinical reports have shown paravertebral spread with erector spinae plane blocks. Both techniques have been found to reduce postoperative pain compared to controls; however, the results have been more inconsistent than with the paravertebral block. Finally, the intertransverse process block targets the tissue complex posterior to the superior costotransverse ligament. Anatomical studies have revealed that this block has pathways that are more direct and closer to the paravertebral space than the retrolaminar and erector spinae plane blocks. Cadaveric evaluations have consistently shown promising results; however, further clinical studies using this technique are needed to confirm these anatomical findings.

Review
Electrodiagnosis for cervical radiculopathy often involves exploration of the cervical paraspinal muscles. Accurate and reproducible results require a technique with specific anatomic localization, direction of insertion, extent of insertion, scoring system for insertion, and criteria for determining abnormality. We sought to understand if a published technique met these criteria. A Medline search found 39 articles with original research and 10 review articles involving the cervical paraspinals. A library search found 19 textbooks since 2000, but 9 were not available. Only two studies were specific to the question. Neither had reproducible techniques and they contradicted each other. Studies in which the paraspinals were used for comparison or inclusion did not provide any specific technique. The review articles and textbooks typically met none of our criteria and the few that discussed technique at all provided no reproducible methods. Despite 80 years of electrodiagnostic testing, there is no useful, reproducible technique for exploring the cervical paraspinal muscles. Yet such a paraspinal mapping technique has proven invaluable in the lumbar region. For cervical electromyography to be of value, the next step is to understand the anatomy and propose a reproducible technique. Subsequent research will determine whether the neck muscles are helpful in the diagnosis of cervical radiculopathy. The absence of a valid reproducible cervical paraspinal technique impedes clinical and scientific understanding of cervical radiculopathy.
