NEWBERN, ) ) Plaintiff, ) ) v. ) Case No. 2:13-CV-31-RWS-NAB ) CAROLYN W. COLVIN, ) Acting Commissioner of Social Security, ) ) Defendant. ) REPORT AND RECOMMENDATION This is an action under 42 U.S.C. § 405(g) for judicial review of the Commissioner of Social Security’s final decision denying Scott L. Newbern’s (“Newbern”) application for benefits under Title II of the Social Security Act, 42 U.S.C. § 401 et seq. Newbern alleged disability due to torn ligaments in the right knee, no bicep muscle in the right arm, steel plate in the neck, diabetes, and Hepatitis C. (Tr. 179.) This matter was referred to the undersigned United States Magistrate Judge pursuant to 28 U.S.C. § 636(b)(1) for a report and recommendation. [Doc. 4.] I. Background On August 12, 2010, Newbern applied for disability insurance benefits. (Tr. 131-136.) The Social Security Administration (“SSA”) denied Newbern’s claim and he filed a timely request for a hearing before an administrative law judge (“ALJ”). (Tr. 65-69, 72-74.) The SSA granted Newbern’s request for review. (Tr. 76-77.) An administrative hearing was held on February 1, 2012. (Tr. 27-54.) The ALJ issued a written opinion upholding the denial of benefits. (Tr. 9-22.) Newbern requested review of the ALJ’s decision from the Appeals Council. (Tr. 5.) On January 28, 2013, the Appeals Council denied Newbern’s request for Case: 2:13-cv-00031-RWS Doc. #: 29 Filed: 02/13/14 Page: 2 of 16 PageID #: <pageID> review. (Tr. 1-3.) The decision of the ALJ thus stands as the final decision of the Commissioner. See Sims v. Apfel, 530 U.S. 103, 107 (2000). Newbern filed this appeal on March 26, 2013. [Doc. 1.] The Commissioner filed an Answer and the certified Administrative Transcript on May 24, 2013. [Docs. 9, 10.] Newbern filed a Brief in Support of Complaint on October 31, 2013. [Doc. 23.] The Commissioner filed a Brief in Support of the Answer on January 27, 2014. [Doc. 28.] II. Standard of Review The Social Security Act defines disability as an “inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or has lasted or can be expected to last for a continuous period of not less than 12 months.” 42 U.S.C. § 423(d)(1)(A). The Social Security Administration uses a five-step analysis to determine whether a claimant seeking disability benefits is in fact disabled. 20 C.F.R. § 404.1520(a)(1). First, the claimant must not be engaged in substantial gainful activity. 20 C.F.R. § 404.1520(a)(4)(i). Second, the claimant must establish that he or she has an impairment or combination of impairments that significantly limits his or her ability to perform basic work activities. 20 C.F.R. § 404.1520(a)(4)(ii). Third, the claimant must establish that his or her impairment meets or equals an impairment listed in the appendix to the applicable regulations. 20 C.F.R. § 404.1520(a)(4)(iii). Fourth, the claimant must establish that the impairment prevents him or her from doing past relevant work. 20 C.F.R. § 404.1520(a)(4)(iv). At step five, the burden shifts to the Commissioner to establish that the claimant maintains the residual functional capacity to perform a significant number of jobs in the national economy. Singh v. Apfel, 222 F.3d 448, 451 (8th Cir. 2 Case: 2:13-cv-00031-RWS Doc. #: 29 Filed: 02/13/14 Page: 3 of 16 PageID #: <pageID> 2000). If the claimant satisfies all of the criteria under the five-step evaluation, the ALJ will find the claimant to be disabled. 20 C.F.R. § 404.1520(a)(4)(v). This Court reviews decisions of the ALJ to determine whether the decision is supported by substantial evidence in the record as a whole. 42 U.S.C. § 405(g). Substantial evidence is less than a preponderance, but enough that a reasonable mind would find adequate support for the ALJ’s decision. Smith v. Shalala, 31 F.3d 715, 717 (8th Cir. 1994). Therefore, even if this Court finds that there is a preponderance of evidence against the weight of the ALJ’s decision, the decision must be affirmed if it is supported by substantial evidence. Clark v. Heckler, 733 F.2d 65, 68 (8th Cir. 1984). An administrative decision is not subject to reversal simply because some evidence may support the opposite conclusion. Gwathney v. Chater, 1043, 1045 (8th Cir. 1997). To determine whether the ALJ’s final decision is supported by substantial evidence, the Court is required to review the administrative record as a whole to consider: (1) The findings of credibility made by the ALJ; (2) The education, background, work history, and age of the claimant; (3) The medical evidence given by the claimant’s treating physician; (4) The subjective complaints of pain and description of the claimant’s physical activity and impairment; (5) The corroboration by third parties of the claimant’s physical impairment; (6) The testimony of vocational experts based upon prior hypothetical questions which fairly set forth the claimant’s physical impairment; and 3 Case: 2:13-cv-00031-RWS Doc. #: 29 Filed: 02/13/14 Page: 4 of 16 PageID #: <pageID> (7) The testimony of consulting physicians. Brand v. Sec’y of Dept. of Health, Educ. & Welfare, 623 F.2d 523, 527 (8th Cir. 1980). III. ALJ’s Decision First, the ALJ determined that Newbern last met the insured status requirements of the Social Security Act on March 31, 2011 and that he had not engaged in any substantial gainful activity from his amended alleged onset date of March 27, 2009 through his date last insured. (Tr. 11.) Second the ALJ found that Newbern had the severe impairments of disc protrusion at L5-S1; multi-level degenerative changes of the cervical spine; status post anterior cervical discectomy and fusion1 (“ACDF”) at C5-C6 and C6-C7; disc herniation at C7-T severe cervical stenosis at C4-C5; moderate cervical stenosis at C5-C6; anterior cruciate ligament2 (“ACL”) repair of the right knee; diabetes; hepatitis C; and obesity. (Tr. 11.) Third, the ALJ determined that Newbern did not have an impairment or combination of impairments that met or medically equaled the severity of one of the listed impairments in 20 C.F.R. Part 404, Subpart P, Appendix 1. (Tr. 13.) The ALJ found that Newbern had the residual functional capacity to perform sedentary work, however, he is limited to occasionally stooping, kneeling, crouching, crawling, balancing, and climbing ramps, stairs, ladders, ropes or scaffolds. (Tr. 15.) Fourth, the ALJ found that Newbern could not return to his past relevant work; but jobs existed in significant numbers in the national economy that he could perform. (Tr. 21.) Finally, the ALJ concluded that Newbern was not under a disability from March 27, 2009 through March 31, 2011. (Tr. 21.) 1 Anterior decompression and fusion is the removal of pressure and fixation of the bones between two or more vertebrae. Stedman’s Medical Dictionary 90, 462, 720-21 (27th ed. 2000). 2 Anterior cruciate ligament is “the ligament that extends from the anterior intercondylar area of the tibia to the posterior part of the medial surface of the lateral condyle of the femur.” Stedman’s Medical Dictionary 997 (27th ed. 2000). 4 Case: 2:13-cv-00031-RWS Doc. #: 29 Filed: 02/13/14 Page: 5 of 16 PageID #: <pageID> IV. Administrative Record The following is a summary of relevant evidence before the ALJ. A. Administrative Hearing At the administrative hearing, the ALJ heard testimony from Newbern and he was represented by counsel. Newbern testified that at the time of the hearing he was 44 years old and the primary care giver to his children, ages 4 and 15. (Tr. 33-34.) Newbern drives daily to his kids’ school, the grocery store, and the doctor’s office. (Tr. 35.) Newbern currently works part-time at McDonald’s where he takes out the trash, cleans the tables, and filters the grease. (Tr. 38.) He works there for 12 to 14 hours per week and he is allowed to take breaks, as needed, if he is hurting. (Tr. 39.) Newbern states that it hurts when he stands too long or has to lift even light things. (Tr. 40.) He cannot lift with his knees so lifting places extra pressure on his neck and back. (Tr. 40.) Newbern testified that he is exhausted and hurting at the end of his shift and is unable to obtain a good rest at night. (Tr. 41.) On work days, the symptoms are worse than the days when he is not working. (Tr. 41.) Newbern testified that neck surgery in March 2009 provided only temporary relief. (Tr. 41.) Newbern states that his hands and fingers are numb, he has pain in his neck and feels like someone is standing on his back and pulling his arms backwards. (Tr. 41-42.) Newbern stated that he cannot grip and cannot carry anything unless he can hold it by the bottom. (Tr. 42.) Newbern has no tricep muscles; therefore, he cannot lift any kind of weight over his head, push up over his head or push anything away from him. (Tr. 42.) He cannot hold his arms out in front of him for an extended length of time.

GAG accumulation affects both primary bone formation and secondary bone growth, resulting in growth impairment. Typical spinal manifestations in MPS are atlantoaxial instability, thoracolumbar kyphosis/scoliosis, and cervical/lumbar spinal canal stenosis. Spinal disorders and their severity depend on the MPS type and may be related to disease activity. Enzyme replacement therapy or hematopoietic stem cell transplantation has advantages regarding soft tissues; however, these therapeutic modalities are not effective for bone or cartilage and MPS-related bone deformity including the spine. Because spinal disorders show the most serious deterioration among patients with MPS, spinal surgeries are required although they are challenging and associated with high anesthesia-related risks. The aim of this review article is to provide the current comprehensive knowledge of representative spinal disease in MPS and its surgical management, including the related pathology, symptoms, and examinations.

Abstract: Degenerative cervical myelopathy (DCM), earlier referred to as cervical spondylotic myelopathy (CSM), is the most common and serious neurological disorder in the elderly popu- lation caused by chronic progressive compression or irritation of the spinal cord in the neck. The clinical features of DCM include localised neck pain and functional impairment of motor function in the arms, fingers and hands. If left untreated, this can lead to significant and permanent nerve damage including paralysis and death. Despite recent advancements in understanding the DCM pathology, prognosis remains poor and little is known about the molecular mechanisms underlying its pathogenesis. Moreover, there is scant evidence for the best treatment suitable for DCM patients. Decompressive surgery remains the most effective long-term treatment for this pathology, although the decision of when to perform such a procedure remains challenging. Given the fact that the aged population in the world is continuously increasing, DCM is posing a formidable challenge that needs urgent attention.

  • (MRI) in the Follow-Up Management of Spinal Injury
    Paraplegw 29 (1991) 39&-410 © 1991 International Medical Society of Paraplegia Paraplegia The value of Magnetic Resonance Imaging (MRI) in the Follow-up Management of Spinal Injury P. Sett, MS, FRCS (SN)/ H. Alan Crockard, FRCS2 [Thorn Research Fellow, 2Consultant Neurosurgeon, The Department of Surgical Neurology, The National Hospitals for Nervous Diseases, Maida Vale, London W9 ITL, UK. Summary Twenty-seven patients with spinal injury have been studied with follow-up Magnetic Resonance Imaging (MRl). MRI has helped (a) to determine the extent of cord injury; (b) to detect continuing compression to the spinal cord; (c) to discover unexpected pathol­ ogies and most importantly (d) to detect the development of post traumatic syrinx. MRI was most valuable in patients with post-traumatic syrinxes to evaluate any changes in the size, and, in those who had a shunting procedure, to assess the efficacy of the procedure. MRI also aided in planning complicated one stage operations by giving a 'complete' picture of the injury inflicted to the vertebrae, soft tissue structures and the spinal cord. As well as advantages in clinical audit it makes financial sense. It provides more infor­ mation than CT myelography and is non-invasive. When compared to the cost of neurological deterioration it is much more cost effective to follow-up spinal injury patients with MRI. It is the authors' contention that after the acute phase all patients with spinal injury should have at least one MRI. Key words: Spinal injury; Magnetic resonance imaging; Post traumatic syringomyelia; Cord compression; Myelomalacia. The incidence of spinal injury varies in the Western world.

Objectives: Our aim was to summarise the history, epidemiology, aetiological mechanism, pathological study, clinical and radiological evaluation, treatment and prognosis of subacute posttraumatic ascending myelopathy (SPAM). Methods: Medical literature on SPAM were searched in the PubMed, Medline, Ovid and Embase databases. The cases of SPAM reported in literature were analysed, and the history, epidemiology, aetiological mechanism, pathological study, clinical and radiological evaluation, treatment and prognosis of SPAM were summarised. Results: SPAM remains a relatively rare disorder occurring within the first few weeks after spinal cord injury (SCI). The incidence rate ranges from 0.42% to 1% among all SCI. SPAM is likely to occur in young and middle-aged male patients. Risk factors of SPAM include complete injury, low blood pressure, early postoperative mobilisation and nonsurgical treatment. Conclusions: SPAM is well recognised according to typical clinical manifestation and magnetic resonance imaging characteristics. There is no effective therapy for this neurological deterioration. The prognosis of SPAM is poor. There is usually a slight improvement of one or more level(s) below the maximal level of deterioration. The mortality rate is approximately 10%.

  • Risk Factors Associated with Progressive Myelomalacia in Dogs
    Castel et al. BMC Veterinary Research (2019) 15:433 https://doi.org/10.1186/s12917-019-2186-0 RESEARCH ARTICLE Open Access Risk factors associated with progressive myelomalacia in dogs with complete sensorimotor loss following intervertebral disc extrusion: a retrospective case-control study Aude Castel1, Natasha J. Olby2,3* , Hongyu Ru2, Christopher L. Mariani2,3, Karen R. Muñana2,3 and Peter J. Early2 Abstract Background: Progressive myelomalacia (PMM) is a usually fatal complication of acute intervertebral disc extrusion (IVDE) in dogs but its risk factors are poorly understood. The objective of this retrospective case-control study was to identify risk factors for PMM by comparing dogs with complete sensorimotor loss following IVDE that did and did not develop the disease after surgery. We also investigated whether any risk factors for PMM influenced return of ambulation. Medical records of client-owned dogs with paraplegia and loss of pain perception that underwent surgery for IVDE from 1998 to 2016, were reviewed. Dogs were categorized as PMM yes or no based on clinical progression or histopathology. Walking outcome at 6 months was established. Signalment, onset and duration of signs (categorized), steroids, non-steroidal anti-inflammatory drugs (yes or no), site of IVDE (lumbar intumescence or thoracolumbar) and longitudinal extent of IVDE were retrieved and their associations with PMM and walking outcome were examined using logistic regression. Results: One hundred and ninety seven dogs were included, 45 with and 152 without PMM. A 6-month-outcome was available in 178 dogs (all 45 PMM dogs and 133 control dogs); 86 recovered walking (all in the control group).

  • Prediction of Neurologic Outcome in Acute Spinal Cord Injury: the Role of CT and MR
    Prediction of Neurologic Outcome in Acute Spinal Cord Injury: The Role of CT and MR Marry Silberstein , 1 Brian M . Tress,2 and O liver Hennessi PURPOSE: 1) To determine whether MR appearances of the spinal cord in acute trauma correlate with clinica l prognosis, and 2) to identify other MR and CT prognostic factors in acute spinal trauma. METHODS: Retrospective eva luation of MR , CT , and cl inica l examinations in 32 acute spinal trauma patients examined between 1987 and 1990. RESULTS: All 21 patients with abnormal spinal cords on MR had complete motor paralysis at presentation, compared to only three of 11 patients with normal cords. Whereas cord transection and hemorrhagic contusion had poor prognoses, 73 % of patients with cord edema and 100% of patients with normal cord had usefu l motor function at outcome. At follow-up MR, areas of cord contusion developed into cysts, while edema resolved , leaving residual areas of myelomalacia. Associated spinal fractures , ligament injury, and cord compression were associated (P < .05) with a worse prognosis. Spondylotic changes were a significant risk factor for spinal cord injury, media ted by cord compression. CONCLUSIONS: MR and CT are valuable techniques for quantifying injury and predicting prognosis in acute spinal tra uma.

  • Progressive Posttraumatic Myelomalacic Myelopathy: Imaging and Clinical Features
    Progressive Posttraumatic Myelomalacic Myelopathy: Imaging and Clinical Features Steven Falcone, Robert M . Quencer, Barth A. Green, Sherri J. Patchen, and M. Judith Donovan Post PURPOSE: To describe the imaging features, surgical management, and clinical outcome of progressive posttraumatic myelomalacic myelopathy (PPMM), a relatively unrecognized but im­ portant cause of progressive myelopathy in patients with previous spinal cord injuries. METHODS: The clinical records, imaging studies, and postoperative outcome of 10 patients with PPMM were reviewed. Fifteen preoperative and five postoperative MRs were analyzed for intramedullary signal abnormalities, the nature of these signal abnormalities, and cord tethering. All patients had intraoperative sonography. RESULTS: Neurologic signs and symptoms found in our patients included 1) progressive loss of motor function (6/1 0), 2) sensory level changes (4/1 0), 3) increased spasticity (4/ 10), 4) autonomic dysreflexia (4/10), 5) loss of bowel or bladder control (4/10), and 6) local and/or radicular pain (4/1 0). Preoperative MR in nine patients revealed intramedullary T1 / T2 lengthening (9/9), extramedullary tethering/ adhesions (9/9), ill-defined lesional borders (6/9), cord expansion (5/9), and increased signal intensity of the lesion on T1-weighted images compared with CSF (7 /9). Proton density images in five patients demonstrated a relative increase in signal intensity over CSF. In all five postoperative MRs, there was evidence of untethering of the spinal cord and a decrease in cord size in two patients. Intraoperative sonography revealed cord tethering and abnormal cord echotexture in all cases. Postoperative clinical evaluation revealed neurologic improvement in nine patients. CONCLUSIONS: PPMM may clinically and radiographically mimic progressive posttraumatic cystic myelopathy (PPCM).

  • Magnetic Resonance Imaging of the Chronically Injured Cervical Spinal Cord
    457 Magnetic Resonance Imaging of the Chronically Injured Cervical Spinal Cord Robert M. Quencer1 Thirteen patients with prior cervical spinal cord injury resulting in quadriplegia were Jerome J. Sheldon2 evaluated with magnetic resonance imaging (MRI) long after their initial injury, either M. Judith Donovan Post1 because of the relatively recent onset of new and worsening neurologic symptoms or Rosendo D. Diaz1 to rule our residual compression on the spinal cord or nerve roots. The results of MRI Berta M. Montalvo1 were compared with delayed metrizamide computed tomography (CT) in 10 cases, and in five of those the results were also compared with intraoperative spinal sonography. Barth A. Green3 4 It was found that MRI more accurately demonstrated the intramedullary abnormalities in Frank J. Eismont the injured spinal cord than did delayed metrizamide CT because the former could separate myelomalacia from a posttraumatic spinal cord cyst, a differentiation that was frequently difficult with delayed metrizamide CT. T2-weighted spin-echo pulsing se­ quences with long echo times were particularly useful in evaluating these patients. Over the years, the radiographic assessment of damage to a previously injured spinal cord has included Pantopaque myelography [1 , 2) , air meylography (3), percutaneous cord puncture [2 , 3) , and , most recently, delayed metrizamide computed tomography (CT) [1 , 3, 4) . Of these, delayed metrizamide CT is the most accurate, because it can detect an abnormal accumulation of water-soluble contrast media within the spinal cord , which suggests the presence of either a posttraumatic spinal cord cyst [4) or myelomalacia (5). Nonetheless, potential diagnostic pitfalls associated with delayed metrizamide CT during preoperative evaluation of a chronically injured spinal cord have been demonstrated by intraoperative spinal This article appears in the May/June 1986 sonography.

  • Post-Traumatic Spinal Cord Cysts Evaluated by Magnetic Resonance Imaging
    Paraplegia 29 (1991) 607-612 © 1991 International Medical Society of Paraplegia Paraplegia Post-traumatic Spinal Cord Cysts Evaluated by Magnetic Resonance Imaging H. A. Backe, MD: R. R. Betz, MD: M. Mesgarzadeh, MD,2 T. Beck, RN, M. Clancy, MDl 1 Shriners Hospitals for Crippled Children, 8400 Rossevelt Boulevard, Philadelphia 2 Unit, Philadelphia, Pennsylvania 19152, Temple University Hospital, 3401 North Broad Street, Philadelphia, PA 19140, USA. Summary In order to determine a more accurate prevalence of post-traumatic spinal cord cysts (PTSCC) in spinal cord injured (SCI) patients, we retrospectively reviewed magnetic resonance scans from symptomatic imaging and asymptomatic SCI patients . We found the incidence of PTSCC to be 51% in our patient population. The only symptom that correlated to the presence of a cyst was spasticity. The cyst develops at the site of injury and appears to be a common sequela of SCI. We believe that conservative treatment is indicated in most patients with a PTSCC. Key words: Post-traumatic spinal cord cyst; Syringomyelia; Paraplegia; Magnetic resonance lmagzng. Post-traumatic spinal cord cysts (P TSCC), or syringomyelia, are cystic lesions which are thought to be a rare sequela of spinal cord injury (SCI), occurring in less than 3·2% of SCI patients (Rossier, 1985). Late deterioration and worsening of neurological function in SCI patients has been attributed to the enlargement of these cysts (Rossier et al., 1985; Barnett and Jousse, 1973; Eismont et al., 1984; Quencer et al., 1983; Dworkin and Staas, 1985; Rossier et al., 1968; Jensen and Reske-Nielsen, 1977). Until the advent of magnetic resonance imaging (MRI), the diagnosis of PTSCC was made using CT myelography.
