RESUMO
Background/Objectives: There exists limited data guiding open-door laminoplasty. The objective of this study is to determine if open-door laminoplasty affects radiographic decompression or arm pain outcomes. Methods: Adult patients who underwent unilateral open-door laminoplasty cervical myelopathy were included. The side opened was dependent on surgeon discretion. We recorded preoperative side of symptoms, side of radiographic compression, arm pain scores, and canal diameter. Patients with open-side ipsilateral or contralateral to dominant symptoms or compression were compared to determine any effect on arm pain outcomes or spinal canal diameter. If the symptoms were equal bilaterally, patients were neutral. Results: A total of 167 patients were included, with an average age of 64 ± 11 years and average follow-up time of 64.5 ± 72 weeks. The average preoperative arm pain visual analog score (VAS) was 2.13 ± 2.86, and the average arm VAS after 6 months was 1.52 ± 2.68. For dominant symptoms, the ipsilateral, contralateral, and neutral groups had a significant improvement in arm VAS at >6 months postoperatively. For dominant compression, the ipsilateral and contralateral groups had a significant improvement in both arm VASs and canal diameter at >6 months postoperatively. No differences were seen between groups for either. We observed a significant correlation between size of plate and change in canal diameter; however, no differences were noted for arm pain. Conclusions: Laminoplasty may be effective in addressing radicular arm pain by increasing the spinal canal's diameter and space available for the cord. The laterality of open-door laminoplasty did not affect arm pain improvement or canal expansion.
RESUMO
A Division I baseball pitcher presented with chronic forearm pain in his throwing arm while pitching. Physical examination was remarkable for point tenderness over the radial tunnel. A postexertion magnetic resonance imaging (MRI) scan revealed edema around the posterior interosseous nerve. The patient underwent decompression of the nerve along with radial tunnel release, which resulted in full resolution of symptoms and return to full baseball activities. Radial tunnel syndrome is a rare phenomenon but can occur in throwing athletes. MRI immediately after a pitching session aided in accurate diagnosis and successful surgical management.
RESUMO
The fascial system (FS) represents a sophisticated and intricate network within the human body, comprising both superficial and deep fascial layers. Disruptions or dysfunctions within this system have been implicated in a variety of musculoskeletal (MSK) disorders and pain syndromes. Specifically, fascial tightness has been associated with diminished range of motion and localized pain. Glucopuncture, a novel therapeutic approach, involves the administration of 5% dextrose injections directly into the fascial layers, such as the superficial fascia, to address these issues. This article presents a case series involving three patients who underwent palpation/ landmark-guided glucopuncture for the treatment of superficial fascial dysfunction. The first case involves a 45-year-old male with a nine-month history of left groin pain, who experienced significant pain relief following glucopuncture below the inguinal ligament, with complete resolution of symptoms within four weeks. The second case describes a 36-year-old female suffering from left arm and neck pain for two years, who reported gradual pain alleviation over six weeks after receiving multiple injections in the fasciae of the neck, scapula, and lateral aspect of the triceps muscle. The final case involves a 67-year-old female with a six-month history of low back and buttock pain, who showed improvement after four weeks following multiple injections in the fasciae of the low back, lumbar region, and buttocks. These cases highlight the potential of palpation-guided glucopuncture as a simple, cost-effective method for modulating regional pain caused by superficial fascial dysfunction. However, further research is necessary to fully ascertain the efficacy and safety of glucopuncture for treating fascial dysfunction.
RESUMO
BACKGROUND: The high thoracic erector spinae plane block (ESPB) has been used for the management of chronic shoulder pain or arthroscopic shoulder surgery. No study has evaluated the analgesic efficacy of ESPB in patients with cervical radiculopathy although it is a favored and easy technique compared to neuraxial block. The purpose of this study was to compare the treatment outcome of cervical radiculopathy using high thoracic ESPB or cervical interlaminar epidural injection (CEPI). METHODS: This study included 82 patients with neck and arm pain who received CEPI (CEPI group) using 4 ml of 0.1% ropivacaine or high thoracic ipsilateral ESPB (ESPB group) at the T2 or T3 level using 20 ml of 0.1% ropivacaine 20 ml. The degree of pain relief and disability were assessed using an 11-point numerical scale (NRS) and neck disability index (NDI), respectively. RESULTS: The CEPI and ESPB groups demonstrated an equal number of patients with excellent pain relief (NRS reduction ≥ 50%). Significant reduction of NRS was found in both groups, and the effect of time was statistically significant in the groups (P < 0.001). The number of patients who showed an excellent improvement in NDI (NDI reduction ≥ 30%) was 20 (48.8%) and 22 (53.7%) in the CEPI and ESPB groups, respectively. CONCLUSIONS: Both the CEPI and ESPB demonstrated significant relief in neck and arm pain with improvement in disability.
RESUMO
OBJECTIVE: A mechanism-based clinical framework for spine-related pain differentiates (i) somatic referred pain, ii) heightened nerve mechanosensitivity, iii) radicular pain, iv) radiculopathy and mixed-pain. This study aimed to determine the reliability of proposed framework. METHOD: Fifty-one people with unilateral spine-related neck-arm pain were assessed and categorized by examiner-1. The classifications were compared to those made by two other examiners, based on written documentation of examiner-1. Cohens kappa was calculated between examiner-pairs; Fleiss Kappa among all examiners to assess agreement in classifying subgroups and entire framework. RESULT: Inter-rater-reliability showed moderate to almost perfect reliability (somatic: no variation, mechanosensitivity: 0.96 (95% CI 0.87-1.0) to 1.0 (95% CI: 1.0-1.0), radicular pain: 0.46 (95% CI: 0.19-0.69) to 0.62 (95% CI: 0.42-0.81), radiculopathy: 0.65 (95% CI: 0.43-0.84) to 0.80 (95% CI: 0.63-0.96) mixed-pain: 0.54 (95% CI: 0.21-0.81) to 0.75 (95% CI: 0.48-0.94). There was almost perfect to moderate reliability among all examiners (somatic: no variation, mechanosensitivity: 0.97 (95% CI: 0.82-1.0), radicular pain: 0.56 (95% CI: 0.40-0.71), radiculopathy: 0.74 (95% CI: 0.58-0.90), mixed-pain: 0.63 (95% CI: 0.47-0.79), entire framework: 0.64 (95% CI: 0.57-0.71)). Intra-rater-reliability showed substantial to almost perfect reliability (somatic: no variation, mechanosensitivity: 0.96 (95% CI: 0.87-1.0), radicular pain: 0.76 (95% CI: 0.57-0.92), radiculopathy: 0.84 (95% CI: 0.67-0.96), mixed-pain: 0.83 (95% CI: 0.60-1.0), entire framework: 0.80 (95% CI: 0.61-0.92). CONCLUSION: Moderate to almost perfect reliability in subgrouping people with spine-related neck-arm pain and substantial reliability for entire framework support this classification's reliability.

OBJECTIVE: Axial neck pain is a prevalent condition that causes significant morbidity and productivity loss. This study aimed to review the current literature and define the impact of surgical intervention on the management of cervical axial neck pain. METHODS: A search was conducted of three databases (Ovid MEDLINE, Embase, and Cochrane) for randomized controlled trials and cohort studies written in the English language with a minimum 6-month follow-up. The analysis was limited to patients with axial neck pain/cervical radiculopathy and preoperative/postoperative Neck Disability Index (NDI) and visual analog scale (VAS) scores. Literature reviews, meta-analyses, systematic reviews, surveys, and case studies were excluded. Two patient groups were analyzed: the arm pain predominant (pAP) cohort and the neck pain predominant (pNP) cohort. The pAP cohort had preoperative VAS neck scores that were lower than the arm scores, whereas the pNP cohort was defined as having preoperative VAS neck scores higher than the arm scores. A 30% reduction in patient-reported outcome measure (PROM) scores from the baseline represented the minimal clinically important difference (MCID). RESULTS: Five studies met the inclusion criteria, involving a total of 5221 patients. Patients with pAP showed a slightly higher percent reduction in PROM scores from baseline than those with pNP. The NDI reduction in patients with pNP was 41.35% (mean change in NDI score 16.3/mean baseline NDI score 39.42) (p < 0.0001), whereas those with pAP had a reduction of 45.12% (15.86/35.15) (p < 0.0001). Surgical improvement was slightly but similarly greater in pNP patients compared with pAP patients (16.3 vs 15.86 points, respectively; p = 0.3193). Regarding VAS scores, patients with pNP had a greater reduction in neck pain, with a change from baseline of 53.4% (3.60/6.74, p < 0.0001), whereas those with pAP had a change from baseline of 50.3% (2.46/4.89, p < 0.0001). The difference in VAS scores for neck pain improvement was significant (3.6 vs 2.46, p < 0.0134). Similarly, patients with pNP had a 43.6% (1.96/4.5) improvement in VAS scores for arm pain (p < 0.0001), whereas those with pAP had 66.12% (4.43/6.7) improvement (p < 0.0001). The VAS scores for arm pain were significantly greater in patients with pAP (4.43 vs 1.96 points, respectively; p < 0.0051). CONCLUSIONS: Overall, despite significant variations in the existing literature, there is mounting evidence that surgical intervention can lead to clinically meaningful improvements in patients with primary axial neck pain. The studies suggest that patients with pNP tend to have better improvement in neck pain than in arm pain. In both groups, the average improvements exceeded the MCID values and reached substantial clinical benefit in all studies. Further research is necessary to identify which patients and underlying pathologies will benefit most from surgical intervention for axial neck pain because it is a multifaceted condition with many causes.

BACKGROUND CONTEXT: Anterior cervical discectomy and fusion (ACDF), the gold standard treatment for radiculopathy and myelopathy, has the potential risk of inducing facet-mediated pain through over-distraction. However, the relationship between the clinical outcomes and facet distraction after ACDF remains unclear. PURPOSE: To measure facet distraction using computed tomography (CT) and compare the results with the clinical outcomes after ACDF. STUDY DESIGN: Retrospective cohort study. PATIENT SAMPLE: A consecutive series of patients (n = 144) who underwent a single-level ACDF were included. OUTCOME MEASURES: Interfacet distance on preoperative and postoperative lateral cervical radiographs and CT. Visual analog scale for neck pain (VASn), and arm pain (VASa), neck disability index (NDI), the Short Form 36-item health survey (SF-36) were used for clinical outcomes. METHODS: Each patient underwent plain radiography of the lateral cervical spine preoperatively, immediately and two years postsurgery. CT was performed preoperatively, and at 3 days and 1-year postsurgery. The inter-facet distance was measured at each time point, and changes in values from the preoperative distance were noted and used for study. Patient-reported outcome measures were obtained preoperatively and at 2-year follow-up. Receiver operating characteristic (ROC) curves were generated to derive the critical facet distraction point. RESULTS: The 3 weeks postoperative VASn score was the most severe and showed a tendency to decrease during the follow-up period. There was a significant positive correlation between the change value of facet distraction measured using CT and 3 weeks postoperative VASn score. ROC curve analysis showed that the cut-off value of Δ facet distraction was 1.8 mm. The over-distraction group (Δ facet distraction ≥1.8 mm, n = 75) showed significantly worse clinical outcomes than the control group (Δ facet distraction <1.8 mm, n = 69), including neck and arm pain VAS scores at all time points until the final 2-year follow-up. CONCLUSION: The change value of facet distraction measured using CT rather than plain radiography correlated better with neck pain, and over-distraction contributed to adverse long-term outcomes, including neck and arm pain after ACDF. Additionally, an over-distraction of ≥1.8 mm may cause radiculopathy of adjacent segments along with facet-mediated axial pain; therefore, cage height should be carefully determined to avoid over-distraction during ACDF.

AIMS: The number of patients undergoing surgery for degenerative cervical radiculopathy has increased. In many countries, public hospitals have limited capacity. This has resulted in long waiting times for elective treatment and a need for supplementary private healthcare. It is uncertain whether the management of patients and the outcome of treatment are equivalent in public and private hospitals. The aim of this study was to compare the management and patient-reported outcomes among patients who underwent surgery for degenerative cervical radiculopathy in public and private hospitals in Norway, and to assess whether the effectiveness of the treatment was equivalent. METHODS: This was a comparative study using prospectively collected data from the Norwegian Registry for Spine Surgery. A total of 4,750 consecutive patients who underwent surgery for degenerative cervical radiculopathy and were followed for 12 months were included. Case-mix adjustment between those managed in public and private hospitals was performed using propensity score matching. The primary outcome measure was the change in the Neck Disability Index (NDI) between baseline and 12 months postoperatively. A mean difference in improvement of the NDI score between public and private hospitals of ≤ 15 points was considered equivalent. Secondary outcome measures were a numerical rating scale for neck and arm pain and the EuroQol five-dimension three-level health questionnaire. The duration of surgery, length of hospital stay, and complications were also recorded. RESULTS: The mean improvement from baseline to 12 months postoperatively of patients who underwent surgery in public and private hospitals was equivalent, both in the unmatched cohort (mean NDI difference between groups 3.9 points (95% confidence interval (CI) 2.2 to 5.6); p < 0.001) and in the matched cohort (4.0 points (95% CI 2.3 to 5.7); p < 0.001). Secondary outcomes showed similar results. The duration of surgery and length of hospital stay were significantly longer in public hospitals. Those treated in private hospitals reported significantly fewer complications in the unmatched cohort, but not in the matched cohort. CONCLUSION: The clinical effectiveness of surgery for degenerative cervical radiculopathy performed in public and private hospitals was equivalent 12 months after surgery.Cite this article: Bone Joint J 2023;105-B(1):64-71.

PURPOSE: By using data from the Norwegian Registry for Spine Surgery, we wanted to develop and validate prediction models for non-success in patients operated with anterior surgical techniques for cervical degenerative radiculopathy (CDR). METHODS: This is a multicentre longitudinal study of 2022 patients undergoing CDR surgery and followed for 12 months to find prognostic models for non-success in neck disability and arm pain using multivariable logistic regression analysis. Model performance was evaluated by area under the receiver operating characteristic curve (AUC) and a calibration test. Internal validation by bootstrapping re-sampling with 1000 repetitions was applied to correct for over-optimism. The clinical usefulness of the neck disability model was explored by developing a risk matrix for individual case examples. RESULTS: Thirty-eight percent of patients experienced non-success in neck disability and 35% in arm pain. Loss to follow-up was 35% for both groups. Predictors for non-success in neck disability were high physical demands in work, low level of education, pending litigation, previous neck surgery, long duration of arm pain, medium-to-high baseline disability score and presence of anxiety/depression. AUC was 0.78 (95% CI, 0.75, 0.82). For the arm pain model, all predictors for non-success in neck disability, except for anxiety/depression, were found to be significant in addition to foreign mother tongue, smoking and medium-to-high baseline arm pain. AUC was 0.68 (95% CI, 0.64, 0.72). CONCLUSION: The neck disability model showed high discriminative performance, whereas the arm pain model was shown to be acceptable. Based upon the models, individualized risk estimates can be made and applied in shared decision-making with patients referred for surgical assessment.

BACKGROUND CONTEXT: Anterior cervical discectomy and fusion (ACDF) is commonly performed in patients with radiculopathy and myelopathy. Although the goal of surgery in patients with radiculopathy is to improve function and reduce pain, patients with myelopathy undergo surgery to halt disease progression. Although the expectations between these preoperative diagnoses are generally understood to be disparate by spine surgeons, there is limited literature demonstrating their discordant outcomes. PURPOSE: To compare improvements in patient reported outcome measures (PROMs) for patients undergoing ACDF for myelopathy or radiculopathy. Secondarily, we analyzed the proportion of patients who attain the minimum clinically important difference (MCID) postoperatively using thresholds derived from radiculopathy, myelopathy, and mixed cohort studies. STUDY DESIGN/SETTING: Single institution retrospective cohort study PATIENT SAMPLE: Patients undergoing primary, elective ACDF with a preoperative diagnosis of radiculopathy or myelopathy and a complete set of preoperative and one-year postoperative PROMs. OUTCOME MEASURES: Outcome measures included the following PROMs: Short-Form 12 Physical Component (PCS-12) and Mental Component (MCS-12) scores, the Visual Analog Scale (VAS) Arm score, and the Neck Disability Index (NDI). Hospital readmissions and revision surgery were also collected and evaluated. METHODS: Patients undergoing an ACDF from 2014 to 2020 were identified and grouped based on preoperative diagnosis (radiculopathy or myelopathy). We utilized "general MCID" thresholds from a cohort of patients with degenerative spine conditions, and "specific MCID" thresholds generated from cohorts of patients with myelopathy or radiculopathy, respectively. Multivariate linear regressions were performed for delta (∆) PROMs and multivariate logistic regressions were performed for both general and specific MCID improvements. RESULTS: A total of 798 patients met inclusion criteria. Patients with myelopathy had better baseline function and arm pain (MCS-12: 49.6 vs 47.6, p=.018; VAS Arm: 3.94 vs 6.02, p<.001; and NDI: 34.1 vs 41.9, p<.001), were older (p<.001), had more comorbidities (p=.014), more levels fused (p<.001), and had decreased improvement in PROMs following surgery compared to patients with radiculopathy (∆PCS-12: 4.76 vs 7.21, p=.006; ∆VAS Arm: -1.69 vs -3.70, p<.001; and ∆NDI: -11.94 vs -18.61, p<.001). On multivariate analysis, radiculopathy was an independent predictor of increased improvement in PCS-12 (ß=2.10, p=.019), ∆NDI (ß=-5.36, p<.001), and ∆VAS Arm (ß=-1.93, p<.001). Radiculopathy patients were more likely to achieve general MCID improvements following surgery (NDI: Odds ratio (OR): 1.42, p=.035 and VAS Arm: OR: 2.98, p<.001), but there was no difference between patients with radiculopathy or myelopathy when using radiculopathy and myelopathy specific MCID thresholds (MCS-12: p=.113, PCS-12: p=.675, NDI: p=.108, and VAS Arm: p=.314). CONCLUSIONS: Patients undergoing ACDF with myelopathy or radiculopathy represent two distinct patient populations with differing treatment indications and clinical outcomes. Compared to radiculopathy, patients with myelopathy have better baseline function, decreased improvement in PROMs, and are less likely to reach MCID using general threshold values, but there is no difference in the proportion reaching MCID when using specific threshold values.

OBJECTIVE: We aim to compare the postoperative clinical outcomes, through patient-reported outcome measures (PROMs) and minimum clinically important difference (MCID), in patients undergoing cervical disc replacement (CDR) with preoperative predominant neck pain (pNP) or arm pain (pAP). METHODS: Patients undergoing primary CDR were separated into pNP or pAP cohorts. Demographic, perioperative characteristics, PROMs at preoperative and postoperative time points, and MCID were compared using inferential statistics. Assessed PROMs included Patient-Reported Outcome Measurement Information System-Physical Function (PROMIS-PF), 12-Item Short Form Physical/Mental Component Score (SF-12 PCS/MCS), visual analog scale (VAS) neck, VAS arm, and Neck Disability Index. RESULTS: There were a total of 84 patients, with 54 patients in the pNP cohort. The pNP cohort showed significant postoperative improvement in all PROMs, except for 6-week and 1-year SF-12 PCS, 1-year SF-12 MCS, and 6-month VAS arm score (P ≤ 0.023, all). The pAP cohort showed significant postoperative improvement in all PROMs, apart from 6-month to 1-year SF-12 PCS, and all SF-12 MCS (P ≤ 0.041, all). Greater MCID achievement rates were found in the pNP cohort for SF-12 MCS (P = 0.030). The pAP cohort had higher MCID achievement rates in VAS arm score and Neck Disability Index (P ≤ 0.046, all). CONCLUSIONS: Independent of predominant pain location, patients reported improved physical function, pain, and disability outcomes. Patients with pNP had higher MCID achievement rates in mental function. Patients with pAP had higher rates of MCID achievement in arm pain and disability outcomes. Considering the predominant location of preoperative pain may be helpful in managing expectations for patients undergoing CDR.

AIMS: The aim of this study was to investigate whether the type of cervical disc herniation influences the severity of symptoms at the time of presentation, and the outcome after surgical treatment. METHODS: The type and extent of disc herniation at the time of presentation in 108 patients who underwent anterior discectomy for cervical radiculopathy were analyzed on MRI, using a four-point scale. These were dichotomized into disc bulge and disc herniation groups. Clinical outcomes were evaluated using the Neck Disability Index (NDI), 36-Item Short Form Survey (SF-36), and a visual analogue scale (VAS) for pain in the neck and arm at baseline and two years postoperatively. The perceived recovery was also assessed at this time. RESULTS: At baseline, 46 patients had a disc bulge and 62 had a herniation. There was no significant difference in the mean NDI and SF-36 between the two groups at baseline. Those in the disc bulge group had a mean NDI of 44.6 (SD 15.2) compared with 43.8 (SD 16.0) in the herniation group (p = 0.799), and a mean SF-36 of 59.2 (SD 6.9) compared with 59.4 (SD 7.7) (p = 0.895). Likewise, there was no significant difference in the incidence of disabling arm pain in the disc bulge and herniation groups (84% vs 73%; p = 0.163), and no significant difference in the incidence of disabling neck pain in the two groups (70.5% (n = 31) vs 63% (n = 39); p = 0.491). At two years after surgery, no significant difference was found in any of the clinical parameters between the two groups. CONCLUSION: In patients with cervical radiculopathy, the type and extent of disc herniation measured on MRI prior to surgery correlated neither to the severity of the symptoms at presentation, nor to clinical outcomes at two years postoperatively.Cite this article: Bone Joint J 2022;104-B(11):1242-1248.

(1) Background: Cervical foraminal stenosis (CFS) is a common cause of axial neck and arm pain. The aim of this study was to determine the relationship between the severity of CFS and clinical symptoms in terms of severity and sidedness. (2) Methods: We retrospectively reviewed 75 consecutive patients with degenerative CFS. We graded 900 foramina from C3-4 to T1-2 using Park's grading system. We collected visual analogue scale (VAS) and neck disability index (NDI) values from the neck and both arms. We analyzed the relationships with CFS grades and total number. We defined four types of left/right dominance of CFS (none, left-dominant, right-dominant, and both) by comparing left and right sides using total counts and maximal grade of CFS, respectively. We compared arm pain sidedness (no arm pain, left-only, right only, and bilateral) among different left and right CFS dominance types. (3) Results: Mean neck and left and right arm VAS scores were 4.4 ± 2.5, 4.9 ± 1.6, and 4.6 ± 2.0, respectively. The mean total NDI was 16.0 ± 8.0. The CFS grade at C3-4 and total count were correlated with neck VAS. Arm VAS was also correlated with CFS grade and total counts. Total NDI score was not correlated with radiological parameters. The presence and sidedness of arm pain were significantly different between left and right CFS dominance groups divided by total count of grade 2 and 3 CFS. (4) Conclusions: The CFS grade and total count were correlated with neck and arm VAS. Arm pain occurred more frequently on the side with more grade 2 and 3 CFS.
RESUMO
OBJECTIVE: The impact of the type of pain presentation on outcomes of spine surgery remains elusive. The aim of this study was to assess the impact of predominant symptom location (predominant arm pain vs predominant neck pain vs equal neck and arm pain) on postoperative improvement in patient-reported outcomes. METHODS: The Quality Outcomes Database cervical spine module was queried for patients undergoing 1- or 2-level anterior cervical discectomy and fusion (ACDF) for degenerative spine disease. RESULTS: A total of 9277 patients were included in the final analysis. Of these patients, 18.4% presented with predominant arm pain, 32.3% presented with predominant neck pain, and 49.3% presented with equal neck and arm pain. Patients with predominant neck pain were found to have higher (worse) 12-month Neck Disability Index (NDI) scores (coefficient 0.24, 95% CI 0.15-0.33; p < 0.0001). The three groups did not differ significantly in odds of return to work and achieving minimal clinically important difference in NDI score at the 12-month follow-up. CONCLUSIONS: Analysis from a national spine registry showed significantly lower odds of patient satisfaction and worse NDI score at 1 year after surgery for patients with predominant neck pain when compared with patients with predominant arm pain and those with equal neck and arm pain after 1- or 2-level ACDF. With regard to return to work, all three groups (arm pain, neck pain, and equal arm and neck pain) were found to be similar after multivariable analysis. The authors' results suggest that predominant pain location, especially predominant neck pain, might be a significant determinant of improvement in functional outcomes and patient satisfaction after ACDF for degenerative spine disease. In addition to confirmation of the common experience that patients with predominant neck pain have worse outcomes, the authors' findings provide potential targets for improvement in patient management for these specific populations.

BACKGROUND: No prior work has explored whether the presence of degenerative spondylolisthesis impacts patient-reported outcome measurements (PROMs) after an anterior cervical discectomy and fusion (ACDF); therefore, the goal of the current study was to determine whether the presence of a spondylolisthesis affects PROMs after an ACDF. METHODS: A retrospective cohort study was conducted on patients over the age of 18 who underwent a 1- or 2-level ACDF. All patients received preoperative standing lateral x-rays and were placed into 1 of 2 groups based on the presence of cervical spondylolisthesis from C2-T1: (1) no spondylolisthesis (NS) group or (2) spondylolisthesis (S) group. Preoperative, postoperative, and delta (postoperative minus preoperative) were recorded and compared between groups via univariate and multivariate analysis. Outcomes reported were the Physical Component Scores of the Short Form-12 (PCS-12), the Mental Component Scores of the Short Form-12 (MCS-12), the Neck Disability Index (NDI), and visual analog scale (VAS) Arm/Neck. RESULTS: A total of 202 patients were included in the final analysis with 154 in the NS group and 48 in the S group. Both patient cohorts reported significant postoperative improvement in PCS-12, NDI, and VAS Arm/Neck. When comparing outcome scores between groups, only MCS-12 delta scores were different between groups, with the S group exhibiting a greater mean delta score (8.3 vs 1.3, P = 0.024) than the NS group after ACDF. Multiple linear regression analysis indicated having spondylolisthesis at baseline was a significant predictor of greater change in MCS-12 than the NS group (ß = 4.841; 95% CI, 0.876, 8.805; P = 0.017). CONCLUSION: Both groups demonstrated significant postoperative improvement in PCS-12, NDI, or VAS Neck/Arm pain scores with no significant differences between groups. Patients with spondylolisthesis were found to have significantly greater improvement scores in MCS-12 scoring than those without spondylolisthesis after ACDF surgery.
RESUMO
STUDY DESIGN: Retrospective comparative study. OBJECTIVE: Whereas smoking has been shown to affect the fusion rates for patients undergoing an anterior cervical discectomy and fusion (ACDF), the relationship between smoking and health-related quality of life outcome measurements after an ACDF is less clear. The purpose of this study was to evaluate whether smoking negatively affects patient outcomes after an ACDF for cervical degenerative pathology. METHODS: Patients with tumor, trauma, infection, and previous cervical spine surgery and those with less than a year of follow-up were excluded. Smoking status was assessed by self-reported smoking history. Patient outcomes, including Neck Disability Index, Short Form 12 Mental Component Score, Short Form 12 Physical Component Score (PCS-12), Visual Analogue Scale (VAS) arm pain, VAS neck pain, and pseudarthrosis rates were evaluated. Outcomes were compared between smoking groups using multiple linear and logistic regression, controlling for age, sex, and body mass index (BMI), among other factors. A P value <.05 was considered significant. RESULTS: A total of 264 patients were included, with a mean follow-up of 19.8 months, age of 53.1 years, and BMI of 29.6 kg/m2. There were 43 current, 69 former, and 152 nonsmokers in the cohort. At baseline, nonsmokers had higher PCS-12 scores than current smokers (P = .010), lower VAS neck pain than current (P = .035) and former (P = .014) smokers, as well as lower VAS arm pain than former smokers (P = .006). Postoperatively, nonsmokers had higher PCS-12 scores than both current (P = .030) and former smokers (P = .035). Smoking status was not a significant predictor of change in patient outcome in multivariate analysis. CONCLUSIONS: Whereas nonsmokers had higher function and lower pain than former or current smokers preoperatively, smoking status overall was not found to be an independent predictor of outcome scores after ACDF. This supports the notion that smoking status alone should not deter patients from undergoing ACDF for cervical degenerative pathology.
RESUMO
Despite normal neurological integrity tests, some patients with non-specific neck-arm pain (NSNAP) have heightened nerve mechanosensitivity upon neurodynamic testing. The aim of this study was to determine whether or not a nerve dysfunction is present in patients with positive neurodynamic tests compared to those with negative neurodynamic tests or healthy controls. Somatosensory profiling using quantitative sensory testing (QST) was established in 40 consecutive patients with unilateral NSNAP; 23 had positive upper limb neurodynamic tests (ULNTPOS) and 17 had negative neurodynamic tests (ULNTNEG) and in 26 healthy controls. QST included measurement of thermal and mechanical detection and pain thresholds in the maximal pain area on the symptomatic side as well as the corresponding contralateral area. Fifty-seven percent of patients with NSNAP had positive neurodynamic tests. Somatosensory profiling revealed a loss of function phenotype in NSNAP patients compared to healthy controls both in the maximal pain area and asymptomatic side. Hyperalgesia (cold, heat and pressure) was present bilaterally in both NSNAP groups. Direct comparison between the patient groups revealed no significant differences in somatosensory profiles. However, the ULNTPOS group demonstrated sensory loss compared to healthy controls in more parameters than the ULNTNEG group. The ULNTNEG subgroup represented an intermediate phenotype between ULNTPOS patients and healthy controls in most detection thresholds as well as thermal and pressure pain thresholds. Even though patients with NSNAP present as a spectrum, it remains unclear whether the sensory changes are indicative of a nerve dysfunction/lesion or rather a marker of altered central pain processing.

OBJECTIVE: Vertebral body sliding osteotomy (VBSO) is a safe, novel technique for anterior decompression in patients with multilevel cervical spondylotic myelopathy. Another advantage of VBSO may be the restoration of cervical lordosis through multilevel anterior cervical discectomy and fusion (ACDF) above and below the osteotomy level. This study aimed to evaluate the improvement and maintenance of cervical lordosis and sagittal alignment after VBSO. METHODS: A total of 65 patients were included; 34 patients had undergone VBSO, and 31 had undergone anterior cervical corpectomy and fusion (ACCF). Preoperative, postoperative, and final follow-up radiographs were used to evaluate the improvements in cervical lordosis and sagittal alignment after VBSO. C0-2 lordosis, C2-7 lordosis, segmental lordosis, C2-7 sagittal vertical axis (SVA), T1 slope, thoracic kyphosis, lumbar lordosis, sacral slope, pelvic tilt, and Japanese Orthopaedic Association scores were measured. Subgroup analysis was performed between 15 patients with 1-level VBSO and 19 patients with 2-level VBSO. Patients with 1-level VBSO were compared to patients who had undergone 1-level ACCF. RESULTS: C0-2 lordosis (41.3° ± 7.1°), C2-7 lordosis (7.1° ± 12.8°), segmental lordosis (3.1° ± 9.2°), and C2-7 SVA (21.5 ± 11.7 mm) showed significant improvements at the final follow-up (39.3° ± 7.2°, 13° ± 9.9°, 15.2° ± 8.5°, and 18.4 ± 7.9 mm, respectively) after VBSO (p = 0.049, p < 0.001, p < 0.001, and p = 0.038, respectively). The postoperative segmental lordosis was significantly larger in 2-level VBSO (18.8° ± 11.6°) than 1-level VBSO (10.3° ± 5.5°, p = 0.014). The final segmental lordosis was larger in the 1-level VBSO (12.5° ± 6.2°) than the 1-level ACCF (7.2° ± 7.6°, p = 0.023). Segmental lordosis increased postoperatively (p < 0.001) and was maintained until the final follow-up (p = 0.062) after VBSO. However, the postoperatively improved segmental lordosis (p < 0.001) decreased at the final follow-up (p = 0.045) after ACCF. CONCLUSIONS: Not only C2-7 lordosis and segmental lordosis, but also C0-2 lordosis and C2-7 SVA improved at the final follow-up after VBSO. VBSO improves segmental cervical lordosis markedly through multiple ACDFs above and below the VBSO level, and a preserved vertebral body may provide more structural support.
RESUMO
INTRODUCTION: Overuse injury in youth overhead athletes remains a concern. The introduction of pitch count guidelines was designed to limit the number of pitches per game. South Carolina is considered a warm weather climate which has been proven to expose overhead athletes to higher risk for injury. The purpose of this study was to detect baseline rates of arm pain and sequelae (injury, surgery, impact on participation) among southern youth baseball/softball players to better counsel players, parents, coaches and league administration on the prevention of arm injury. METHODS: A survey was distributed to 14 pediatric practices within the South Carolina Pediatric Practice Research Network. The 2-page survey included 28 closed-ended and descriptive questions that investigated physical and psychosocial responses during and after play. Additional questions were conducted on adherence and understanding of USA Baseball guidelines and pitch counting behavior. RESULTS: Two hundred and seventy three surveys were completed by parents of baseball/softball players. The players' average age was 11.6 years, who played on an average of 1.78 teams/leagues for 5.2 months each year. Only 26% of baseball players answered "Sometimes", "Often" or "Always" to their arm hurting. Arm fatigue, older age, parent/coach frustration with play, and months played were statistically significantly associated with arm pain. The survey revealed 58.9% of families were familiar with pitch count guidelines. DISCUSSION: Arm pain is relatively prevalent among the South Carolina youth baseball community and worse in older players and experience fatigue. This survey found lower percentage of youth overhead athletes experiencing arm discomfort when compared to prior studies. It is important for warm weather climate athletes to abide by guidelines, as they are more susceptible to arm injury. Increased recognition, education and compliance with pitch count guidelines will help protect these youth athletes from overuse injury. LEVEL OF EVIDENCE: IV, Descriptive Epidemiology Study.
RESUMO
CONTEXT: Sport specialization is thought to be a primary contributor to the throwing-related injury risk in youth baseball players. OBJECTIVE: To (1) establish arm-injury incidence in a cohort of male youth (9-12 years old) baseball players and (2) examine sport specialization and the frequency of arm injuries in the same cohort. DESIGN: Cohort study. SETTING: Greenville, South Carolina, youth baseball programs and tournaments. PATIENTS OR OTHER PARTICIPANTS: A total of 159 asymptomatic youth baseball players (age = 11.1 ± 1.1 years) were physically assessed and then were prospectively followed for 6.7 ± 1.5 months. MAIN OUTCOME MEASURE(S): Athlete demographics and playing and injury histories were initially recorded. Athlete-exposures and presence of arm injury were prospectively tracked. All injuries were physically confirmed by a licensed physical therapist. RESULTS: Youth players demonstrated an arm-injury incidence rate of 2.22 per 1000 athlete-exposures. Parents and players underestimated sport-specialization status based on the standard research definition (self versus research based: 31% versus 83%, respectively; P = .001). The frequency of arm injuries was higher in specialized players (100%) than in nonspecialized players (80%, P = .03) but did not differ between pitchers and position players (13.2% each, P = 1.00). CONCLUSIONS: Sport specialization was associated with throwing-related arm injuries in a small cohort of youth baseball players. It is concerning that 57.9% of parents and specialized players were unaware of the athletes' status. Larger studies with longer follow-up periods are needed to further evaluate injury-risk profiles in physically developing youth populations.
