Object Although MRI with short-term T1 inversion recovery (STIR) sequencing has been widely adopted in the clearance of cervical spine in adults who have sustained trauma, its applicability for cervical spine clearance in pediatric trauma patients remains unclear. The authors sought to review a Level 1 trauma center's experience using MRI for posttraumatic evaluation of the cervical spine in pediatric patients. Methods A pediatric trauma database was retrospectively queried for patients who received an injury warranting radiographic imaging of the cervical spine and had a STIR-MRI sequence of the cervical spine performed within 48 hours of injury between 2002 and 2011. Demographic, radiographic, and outcome data were retrospectively collected through medical records. Results Seventy-three cases were included in the analysis. The mean duration of follow-up was 10 months (range 4 days–7 years). The mean age of the patients at the time of trauma evaluation was 8.3 ± 5.8 years, and 65% were male. The majority of patients were involved in a motor vehicle accident. In 70 cases, the results of MRI studies were negative, and the patients were cleared prior to discharge with no clinical suggestion of instability on follow-up. In 3 cases, the MRI studies had abnormal findings; 2 of these 3 patients were cleared with dynamic radiographs during the same admission. Only 1 patient had an unstable injury and required surgical stabilization. The sensitivity of STIR MRI to detect cervical instability was 100% with a specificity of 97%. The positive predictive value was 33% and the negative predictive value was 100%. Conclusions Although interpretation of our results are diminished by limitations of the study, in our series, STIR MRI in routine screening for pediatric cervical trauma had a high sensitivity and slightly lower specificity, but may have utility in future practices and should be considered for implementation into protocols.

✓ Eighty-eight consecutive patients underwent anterior cervical discectomy (ACD) with banked fibula fusion and internal fixation using the locking cervical plate. Pathology included cervical spondylotic radiculopathy in 48, cervical spondylotic radiculomyelopathy in 30, cervical facet dislocations with associated disc herniations in six, and autologous iliac crest graft collapse pseudoarthrosis with recurrent symptoms in four patients. Operations were single-level banked fibula fusion with plating in 37, multilevel banked fibula fusion with plating in 45, and combined single-level ACD banked fibula fusion with plating and posterior fusion in six patients. The only perioperative complication was transient hoarseness. There were no transfusions, infections, neurological injuries, or deaths. The mean time in the hospital for the nontraumatic cases was 1.8 days. The mean follow up was 22 months (range 12–30 months). There has been no motion at the fused level on flexion/extension films, no kyphosis, no screw plate backout, and no banked fibula has suffered graft collapse. Following a high-speed motor vehicle accident 6 months after a multilevel fusion, one alcoholic man suffered a fractured plate with transient worsening of neck pain, and the plate has remained in place for an additional 11 months of follow-up care. Compared to 100 consecutive autologous iliac crest fusions performed by the same surgeon, there were significantly fewer graft-related complications (p < 0.001). There was a significantly greater chance of autologous iliac crest collapsing with the passage of time as compared to banked fibula. Time until return to work was shorter by 5 weeks for the plate/banked fibula group (p < 0.05). When fusion is considered following ACD, the combination of banked fibula and locking cervical plates is significantly superior to autologous iliac crest grafts.

Abstract Background Extreme obesity leads to increased health risks and perioperative complications. The results of bariatric surgery in patients with super-super obesity (SSO) are presented in this study. Methods From April 2008 to August 2019, 60 patients with SSO underwent bariatric surgery. Their weight loss and surgical outcome were analyzed. The mean follow-up time was 7.2 years. Results At baseline, the mean age was 41.5 years old, the mean BMI was 63.8 kg/m2, 80% of the patients suffered from co-morbidities, and 23.33% were revisional surgeries. Weight loss continued for up to two years after surgery. The percentage of EBW lost at two years was 62.27%, from two to five years: 61.48%, from five to 10 years: 36.82% and after ten years it was 31.89%, the differences in weight change over the time is significative (P<.001). The mean BMI at last visit (Mean 7.2 years) was 45.1 kg/m2 and 48.33% of the patients failed to lose at least 50% of EBW. Patients with fatty liver, diabetes, sleep apnea and hyperlipidemia had a remission or improvement in more than 70% of the cases. There were 5% perioperative complications, one perioperative death (1.67%) and other patient died in a motor vehicle accident, overall mortality 3.33%. Conclusion In the long term, almost half of the patients failed to lose 50% of their EBW. However, the metabolic effects of bariatric surgery were maintained during the follow-up time with a high remission of comorbidities. Revisional bariatric surgery increased the risk of mortality.

Object. Despite the wide use of anterior cervical instrumentation in the management of multilevel cervical spondylosis, the incidences of pseudarthrosis and instrument-related failure remain high. The use of a dynamic implant may aid in the prevention of these complications. The purpose of this study was to evaluate the DOC dynamic cervical implant in the treatment of multilevel cervical spondylosis. Methods. The authors evaluated 34 cases in which anterior multilevel cervical decompression and fusion were performed using the DOC Ventral Cervical Stabilization System. Postoperatively, and at each follow-up visit, the sagittal angle and the degree of subsidence that developed were measured. Fusion rates and clinical outcomes were also evaluated. The mean postoperative sagittal angle was 14° of lordosis. The mean change in the sagittal angle during the follow-up period was 0.4° of lordosis. By 6 months postoperatively some subsidence had occurred in most patients, with no subsidence occurring in only 15%. By 3 months greater than or equal to 2 mm of subsidence was demonstrated in 61% of cases. The overall fusion rate was 91%. In the majority of patients (79%) symptoms were judged to be improved or resolved. Conclusions. The DOC dynamic cervical implant permitted controlled subsidence and prevented progression of kyphotic deformity. There was one construct failure (related to a motor vehicle accident) and an overall fusion rate of 91%. The DOC implant is a safe and effective cervical construct for multilevel spondylotic disease.

Recurrent Anterior Shoulder Instability

Background: Recent studies have demonstrated equivalent short-term results when comparing arthroscopic versus open anterior shoulder stabilization. However, none have evaluated the long-term clinical outcomes of patients after arthroscopic or open anterior shoulder stabilization, with inclusion of an assessment of preoperative glenoid tracking. Purpose: To compare long-term clinical outcomes of patients with recurrent anterior shoulder instability randomized to open and arthroscopic stabilization groups. Additionally, preoperative magnetic resonance imaging (MRI) studies were used to assess whether the shoulders were “on-track” or “off-track” to ascertain a prediction of increased failure risk. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A consecutive series of 64 patients with recurrent anterior shoulder instability were randomized to receive either arthroscopic or open stabilization by a single surgeon. Follow-up assessments were performed at minimum 15-year follow-up using established postoperative evaluations. Clinical failure was defined as any recurrent dislocation postoperatively or subjective instability. Preoperative MRI scans were obtained to calculate the glenoid track and designate shoulders as on-track or off-track. These results were then correlated with the patients’ clinical results at their latest follow-up. Results: Of 64 patients, 60 (28 arthroscopic and 32 open) were contacted or examined for follow-up (range, 15-17 years). The mean age at the time of surgery was 25 years (range, 19-42 years), while the mean age at the time of this assessment was 40 years (range, 34-57 years). The rates of arthroscopic and open long-term failure were 14.3% (4/28) and 12.5% (4/32), respectively. There were no differences in subjective shoulder outcome scores between the treatment groups. Of the 56 shoulders, with available MRI studies, 8 (14.3%) were determined to be off-track. Of these 8 shoulders, there were 2 surgical failures (25.0%; 1 treated arthroscopically, 1 treated open). In the on-track group, 6 of 48 had failed surgery (12.5%; 3 open, 3 arthroscopic [ P = .280]). Conclusion: Long-term clinical outcomes were comparable at 15 years postoperatively between the arthroscopic and open stabilization groups. The presence of an off-track lesion may be associated with a higher rate of recurrent instability in both cohorts at long-term follow-up; however, this study was underpowered to verify this situation.

Abstract BACKGROUND Retroclival epidural hematomas (REDHs) are infrequently reported. To our knowledge, only 19 case reports exist in the literature. OBJECTIVE This study was performed to better elucidate this pathology. METHODS We prospectively collected data for all pediatric patients diagnosed with REDH from July 2006 through June 2009. Data included mechanism of injury, Glasgow Coma Scale score, neurological examination, treatment modality, and outcome. Magnetic resonance imaging was used to measure REDH dimensions. RESULTS Eight children were diagnosed with REDH, and the hematomas were secondary to motor vehicle–related trauma in all cases. The mean age of patients was 12 years (range 4–17 years). The mean REDH height (craniocaudal) was 4.0 cm, and the mean thickness (dorsoventral) was 1.0 cm. At presentation, the mean Glasgow Coma Scale score was 8 (range 3–14), and there was no correlation between hematoma size and presenting symptoms. Two patients died soon after injury, and 2 additional patients had atlanto-occipital dislocation that required surgical intervention. No patient underwent surgical evacuation of the REDH. The mean follow-up was 14 months. At most recent follow-up, 4 patients are neurologically intact, 1 patient has a complete spinal cord injury, and 1 patient has mild bilateral abducens nerve palsy. CONCLUSION To our knowledge, this study of 8 pediatric patients is the largest series of patients with REDH thus far reported. Based on our study, we found that REDH is likely to be underdiagnosed, atlanto-occipital dislocation should be considered in all cases of REDH, and many patients with REDH will have minimal long-term neurological injury.

AbstractIntroduction:Current paramedic training mandates complete immobilization of all patients, symptomatic or not, whose mechanism of injury typically is viewed as conducive to spinal trauma. It is common to observe confrontations between paramedics and walking, asymptomatic accident victims who fail to understand why they should “wear that collar and be strapped to that board.” Immobilized, frustrated patients then may wait for hours in a busy emergency department until a physician declares them to be without spinal injury. Patients frequently refuse treatment and transport.Hypothesis:Algorithms exist for physicians to “clear” the cervical spine (C-spine) without radiography. It was hypothesized that paramedics routinely assess and document these indicators in their patient evaluations.Methods:A retrospective chart review was conducted on 161 patients (Group 1) admitted to a regional medical center with a diagnosis of C-spine injury over a 52-month period. The charts of 225 motor vehicle accident (MVA) victims (Group 2) transported by ambulance to the emergency department over a five-month period then were studied. Indicators for C-spine injury documented by emergency medical service (EMS) personnel were abstracted.Results:All patients underwent mental status assessment and full spinal immobilization (neck and back) by EMS crews prior to transport to the hospital. Two or more indicators of possible C-spine injury were documented on each prehospital care report (PCR).Conclusion:Paramedics already assess most, if not all, of the criteria standard to C-spine clearance algorithms, but are inconsistent in their documentation of the presence or absence of all of the relevant findings.

✓ A case is reported of a 45-year-old man who developed quadriplegia following a trivial motor-vehicle accident. Investigation including computerized tomography (CT) of the cervical spine revealed a large calcified lesion displacing the spinal cord and nerve roots, which proved to be a tuberculoma. The case is unusual in regard to the age of the patient, the size, location, and nature of the lesion, the mode of presentation, and the delineation of the lesion by CT scanning.

Introduction: The intrarenal resistance index (RI) is a calculated parameter for the assessment of the status of the graft during the follow-up ultrasound of the transplanted kidney. Currently it is still unclear the predictive value of RI, also in function of the time. Materials and Methods: We retrospectively investigated the correlation between the RI and the graft survival (GS) and the overall survival (OS) after transplantation. We evaluated 268 patients transplanted between 2003 and 2011, the mean followup was 73 months (12-136). The RI was evaluated at 8 days, 6 months, 1 year and 3 years. The ROC analysis was used to calculate the predictive value of RI and the Kaplan Mayer curves was used to evaluated the OS and PS. Results: The ROC analysis, correlated to the GS, identified a value of RI equal to 0.75 as a cut-off. All patients was stratified according to the RI at 8 days (RI ≤ 0,75: 212 vs RI &gt; 0.75: 56), at 6 months (RI ≤ 0.75: 237 vs RI &gt; 0.75: 31), at 1 year (RI ≤ 0.75: 229 vs RI &gt; 0.75: 39) and at 3 years (RI ≤ 0.75: 224 vs RI &gt; 0.75: 44). The RI showed statistically significant differences between the two groups in favor of those who had an RI ≤ 0.75 only at 8 days and at 6 moths (p = 0.0078 and p = 0.02 to 8 days to 6 months) on the GS. On the contrary, we observed that the RI estimated at 1 year and 3 years has not correlated with the GS. The same RI cut-off was correlate with PS after transplantation. We observed that there are no correlations between the RI and OS. Conclusions: The RI proved to be a good prognostic factor on survival organ when it was evaluated in the first months of follow- up after transplantation. This parameter does not appear, however, correlate with OS of the transplanted subject.
