Importance of achieving Scoliosis Research Society-22r minimal clinically important difference for improving patient satisfaction after adult spinal deformity surgery
This study aimed to elucidate factors affecting patient satisfaction after thoracopelvic corrective fusion surgery in patients with ASD.METHODS: Data obtained in 187 patients with ASD who underwent extensive corrective fusion surgery from the thoracic spine to the pelvis between 2010 and 2017 and underwent follow-up for 2 years were retrospectively reviewed. The authors investigated the likelihood of achieving MCIDs in the function, pain, self-image, mental health, and subtotal domains 2 years after surgery. The following MCID values were used: function, 0.90; pain, 0.85; self-image, 1.05; mental health, 0.70; and subtotal...

Impact of focal apex angle on postoperative decompression status of the spinal cord and neurological recovery after cervical laminoplasty
CONCLUSIONS: NRR depends on preoperative SCA type; however, it is possible to change the type of SCA after laminoplasty. Preoperative FA and C2-7 angles influence change in SCA; therefore, they are important parameters for successful decompression with cervical laminoplasty.PMID:34298506 | DOI:10.3171/2020.12.SPINE201831 (Source: Journal of Neurosurgery.Spine)

Retrograde ejaculation following anterior lumbar surgery: a systematic review and pooled analysis
CONCLUSIONS: In a pooled analysis of currently published data on men undergoing first-time open anterior lumbar surgery, this study found an overall incidence of RE of 2.3%. Nearly half of these patients recovered, reporting resolution of symptoms anywhere between 3 months and 48 months. Analysis of risk factors was limited by a paucity of published literature segregating data by sex. However, there was an increased risk associated with rhBMP-2 only when including data collected prior to the FDA warning on its detrimental properties. The authors therefore posit that the risk of RE is probably overestimated in the literatur...

CONCLUSIONS: In a pooled analysis of currently published data on men undergoing first-time open anterior lumbar surgery, this study found an overall incidence of RE of 2.3%. Nearly half of these patients recovered, reporting resolution of symptoms anywhere between 3 months and 48 months. Analysis of risk factors was limited by a paucity of published literature segregating data by sex. However, there was an increased risk associated with rhBMP-2 only when including data collected prior to the FDA warning on its detrimental properties. The authors therefore posit that the risk of RE is probably overestimated in the literatur...

Does minimally invasive spine surgery improve outcomes in the obese population? A retrospective review of 1442 degenerative lumbar spine surgeries
CONCLUSIONS: Obese patients have poorer outcomes after posterior lumbar MIS when compared with nonobese patients. The use of an MIS technique can be of benefit, as it decreased EBL, operative time, LOS, and SSIs for posterior decompression with or without instrumented fusion in obese patients.PMID:34271544 | DOI:10.3171/2021.1.SPINE201785 (Source: Journal of Neurosurgery.Spine)

Removal of instrumentation for postoperative spine infection: systematic review
CONCLUSIONS: The data on this topic remain heterogeneous and low in quality. Retention may be preferred in the setting of early infection, when the risk of underlying spine instability is still high and the risk of mature biofilm formation on the implants is low. However, late infections likely favor instrumentation removal. Higher-quality evidence from large, multicenter, prospective studies is needed to reach generalizable conclusions capable of guiding clinical practice.PMID:34243152 | DOI:10.3171/2020.12.SPINE201300 (Source: Journal of Neurosurgery.Spine)

The associations between radiological and neurological findings of degenerative cervical myelopathy: radiological analysis based on kinematic CT myelography and evoked potentials of the spinal cord
CONCLUSIONS: This study found that the Hoffmann reflex is associated with chronic and severe spinal cord compression but not the dynamic factors. The Babinski sign is associated with severe spinal cord compression during neck flexion. The GTP is associated with large cervical lordosis. These imaging features can help us understand the characteristics of the neurological findings.PMID:34243153 | DOI:10.3171/2020.11.SPINE201626 (Source: Journal of Neurosurgery.Spine)

Antimicrobial prophylaxis in noninstrumented spine surgery: a prospective study to determine efficacy and drawbacks
J Neurosurg Spine. 2021 Jul 9:1-10. doi: 10.3171/2020.11.SPINE201891. Online ahead of print.ABSTRACTOBJECTIVE: The authors sought to evaluate the roles of perioperative antibiotic prophylaxis in noninstrumented spine surgery (NISS), both in postoperative infections and the impact on the selection of resistant bacteria. To the authors' knowledge, only one prospective study recommending preoperative intravenous (IV) antibiotics for prophylaxis has been published previously.METHODS: Two successive prospective IV antibiotic prophylaxis protocols were used: from 2011 to 2013 (group A: no prophylactic antibiotic) and from 2014 t...

Should L3 be selected as the lowest instrumented vertebra in patients with Lenke type 5C adolescent idiopathic scoliosis whose lowest end vertebra is L4?
CONCLUSIONS: In Lenke type 5C AIS patients with posterior selective TL/L fusion to L3 as the LIV, patients with their LEVs at L4 showed postoperative MT and TL/L curve progression; however, no significant differences were observed in global alignment and clinical outcome.PMID:34243158 | DOI:10.3171/2020.11.SPINE201807 (Source: Journal of Neurosurgery.Spine)

Does transforaminal lumbar interbody fusion induce lordosis or kyphosis? Radiographic evaluation with a minimum 2-year follow-up
In this study, the authors' aim was to identify factors that result in kyphosis or lordosis after TLIF.METHODS: A single-center, retrospective study of open TLIF without osteotomy for spondylolisthesis with a minimum 2-year follow-up was undertaken. Preoperative and postoperative clinical and radiographic parameters and cage specifics were collected. TLIFs were considered to be "lordosing" if postoperative induction of lordosis was> 0° and "kyphosing" if postoperative induction of lordosis was ≤ 0°.RESULTS: A total of 137 patients with an average follow-up of 52.5 months (range 24-130 mont...

Safety of direct injection of oligodendrocyte progenitor cells into the spinal cord of uninjured G öttingen minipigs
CONCLUSIONS: These data strongly support the safety of intraparenchymal injection of LCTOPC1 into the spinal cord using a model anatomically similar to that of the human spinal cord. Furthermore, this research provides guidance for future clinical interventions, including mechanisms for precise positioning and anticipated volumes of biological payloads that can be safely delivered directly into uninjured portions of the spinal cord.PMID:34243160 | DOI:10.3171/2020.12.SPINE201853 (Source: Journal of Neurosurgery.Spine)

Surgical outcomes for late neurological deficits after long segment instrumentation for degenerative adult spinal deformity
CONCLUSIONS: The incidence of PJF with late neurological deficits following ASD surgery was 4.7% in this cohort. The patients showed several morphological features. After revision surgery, perioperative complications were common and the prognosis for improved neurological status was not favorable.PMID:34243161 | DOI:10.3171/2020.12.SPINE20604 (Source: Journal of Neurosurgery.Spine)

The change in postoperative opioid prescribing after lumbar decompression surgery following state-level opioid prescribing reform
CONCLUSIONS: Patients undergoing surgery in the year after the implementation of a state-level opioid prescribing reform received significantly fewer MEDs while reporting no change in the total number of opioid prescriptions, PROs, or postoperative ED visits or hospital readmissions. These results demonstrate that state-level reforms placing reasonable limits on opioid prescriptions written for acute pain may decrease patient opioid exposure without negatively impacting patient outcomes after lumbar decompression surgery.PMID:34243163 | DOI:10.3171/2020.11.SPINE201046 (Source: Journal of Neurosurgery.Spine)
