Penetrating cerebral injuries caused by foreign bodies are rare in civilian neurosurgical trauma, although there are various reports of blast or gunshot injuries in warfare due to multiple foreign bodies like pellets and nails. In our case, a 30-year-old man presented to neurosurgery clinic with signs and symptoms of right-sided weakness after suicide bomb attack. The skull X-ray showed a single intracranial nail. Small craniotomy was done and the nail was removed with caution to avoid injury to surrounding normal brain tissue. At 6 months'follow-up his right-sided power improved to against gravity.

OBJECTIVETo examine the contribution of flexion and extension radiographs in the evaluation of ligamentous injury in awake adults with acute blunt cervical spine trauma, who show loss of cervical lordosis and neck pain.

METHODSAll patients who presented to our emergency department following blunt trauma were enrolled in this study, except those with schiwora, neurological deficits or fracture demonstrated on cross-table cervical spine X-rays, and those who were either obtunded or presented after cervical spine surgery. Adequacy of flexion and extension views was checked by the neurosurgery and radiology team members. All these patients underwent cross-table cervical spine view followed by flexion/extension views based on the loss of lordosis on cross-table imaging and the presence of neck pain.

RESULTSA total of 200 cases were reviewed, of whom 90 (45%) underwent repeat X-rays because of either inadequate exposure or limited motion. None of the patients with loss of lordosis on cross-table view had positive flexion and extension views of cervical spine for instability.

CONCLUSIONSOur results show that in patients who underwent acute radiographic evaluation of blunt cervical spine trauma, flexion and extension views of the cervical spine are unlikely to yield positive results in the presence of axial neck pain and/or loss of cervical lordosis. We can also hypothesize that performing flexion and extension views will be more useful once the acute neck pain has settled.

OBJECTIVETo determine the frequency of altered findings on repeat cranial tomography (CT) in patients with mild head injury along with stable neurological examination at tertiary care hospital.

METHODSCross-sectional study was done in the Department of Radiology, Liaquat National Hospital, Karachi from January 2008 to September 2010. All patients with mild head injury in terms of Glasgow Coma Scale (GCS) who underwent repeat scan without clinical or neurological deterioration in the emergency department of a tertiary care centre were included. The collected data were accordingly entered and analyzed by the principal investigator using Statistical Package for Social Sciences (SPSS) version 16.0.

RESULTSIn all 275 patients, only 17 (6%) of the patients were found worseing on repeat CT, 120 (43.63%) scans improved, 138 (50.18%) unchanged and 17 (6.18%) worsened. None of these patients showed signs of clinical deterioration.

CONCLUSIONOur results suggest that for patients with mild head injury and stable neurological examination, only 6% of them show deterioration on repeat CT, especially when patients'GCS is below 13.

STUDY DESIGN: This is a case series. PURPOSE: We wanted to identify variations in the practice patterns among neurosurgeons and orthopedic surgeons for the management of spinal disorders. OVERVIEW OF LITERATURE: Spinal disorders are common in the clinical practice of both neurosurgeons and orthopedic surgeons. It has been observed that despite the availability of various guidelines, there is lack of consensus among surgeons about the management of various disorders. METHODS: A questionnaire was distributed, either directly or via e-mail, to the both the neurosurgeons and orthopedic surgeons who worked at 5 tertiary care centers within a single region of Korea. The surgeons were working either in private practice or in academic institutions. The details of the questionnaire included demographic details and the specialty (orthopedic/neurosurgeon). The surgeons were classified according to the level of experience as up to 5 years, 6-10 years and > 10 years. Questions were asked about the approach to lumbar discectomy (fragmentectomy or aggressive disc removal), using steroids for treating discitis, the fusion preference for spondylolisthesis, the role of an orthosis after fusion, the preferred surgical approach for spinal stenosis, the operative approach for spinal trauma (early within 72 hours or late > 72 hours) and the role of surgery in complete spinal cord injury. The data was analyzed using SPSS ver 16. p-values < 0.05 were considered to be significant. RESULTS: Of the 30 surgeons who completed the questionnaire, 20 were neurosurgeons and 10 were orthopedic surgeons. Statistically significant differences were observed for the management of spinal stenosis, spondylolisthesis, using an orthosis after fusion, the type of lumbar discectomy and the value of surgical intervention after complete spinal cord injury. CONCLUSIONS: Our results suggest that there continues to exist a statistically significant lack of consensus among neurosurgeons and orthopedic spine surgeons when considering using an orthosis after fusion, the type of discectomy and the value of intervention after complete spinal injury.

STUDY DESIGN: Retrospective case series. PURPOSE: The objective of our study was to determine the change in management brought about by magnetic resonance imaging (MRI) of the cervical spine in alert and awake patients with facet dislocation and spinal cord injury presenting within 4 hours after injury. OVERVIEW OF LITERATURE: Spinal cord injury is a common clinical entity. The role of MRI is well established in evaluating spinal trauma. However, the time at which MRI should be used is still controversial. METHODS: Retrospective data from 2002-2010 was evaluated. All of the alert and awake patients with spinal cord injury, based on clinical examination with facet dislocation diagnosed on lateral cervical spine X-rays, were included. A questionnaire was also conducted, the data of which consisted of demographic details including age and sex, the mechanism of injury, clinical examination, X-ray findings, MRI findings, whether or not surgery was performed and the time elapsed since injury. Data was analyzed using SPSS ver. 17.0. Continuous variables such as age were expressed in terms of mean +/- standard deviation. Categorical variables such as change in management, X-ray/MRI findings and neurological motor level were assessed in terms of percentage. RESULTS: Fifty patients participated in our study. All these patients had spinal cord injury with defined motor levels. The mean age was 35.5 +/- 8.95 years (range, 20 to 52 years). Fifty percent showed a motor level at C6 level. None of the patients required any change in management based on the MRI. CONCLUSIONS: MRI of the spine in awake patients within 4 hours after injury does not change the management of patients. However, we can hypothesize that such patients can proceed to traction without waiting for the MRI.

STUDY DESIGN: Observational, case series. PURPOSE: To determine the sensitivity and specificity of clinical judgment as compared to the use of X-ray images in detecting cervical spine injuries in trauma patients presenting in the emergency department of Aga Khan University Hospital, Karachi. OVERVIEW OF LITERATURE: Cross-table cervical spine views are important in patients with signs and symptoms relating to cervical spine, but asymptomatic patients constitute a different subgroup. Accuracy of clinical examination in these patients has not been subjected to scrutiny. METHODS: All patients with blunt trauma who presented to the emergency department and underwent cross-table X-rays as part of their trauma workup were included. The X-rays were read by a radiologist not aware of the history of the patients. We recorded demographic data along with mechanism of injury, associated neck signs or symptoms whether present or not, cervical spine range of motion, associated injuries and X-ray findings. The history and examination were carried out by the on-call neurosurgery team member. The sensitivity and specificity along with negative and positive predictive value of the clinical examination were calculated. Data were analyzed using SPSS ver. 16.0. RESULTS: Of 50 patients with positive signs and symptoms, 4 (8%) had positive X-rays while only 1 out of 324 (0.3%) with no associated signs and symptoms had positive X-ray findings. CONCLUSIONS: The clinical examination is 80% sensitive and 73.98% specific in detecting true cervical spine injuries as compared to C-spine X-rays in alert and awake patients with blunt trauma.

STUDY DESIGN: Cross sectional study. PURPOSE: The purpose of this study was to determine the incidence and the associated risk factors of pinhole type of durotomy and cerebrospinal fluid (CSF) leakage following a simple laminectomy for spinal stenosis. OVERVIEW OF LITERATURE: The incidence of spinal stenosis is expected to rise with increasing life expectancy. Moreover, lumbar spinal stenosis is the most common indication for spinal injury in the geriatric population. It is therefore important to identify and prevent the risks associated with laminectomy, the most widely used surgical procedure for spinal stenosis. The serious complication of incidental dural tear or durotomy and subsequent CSF leakage has not been studied in the region of Southeast Asia. METHODS: In this cross sectional study, we included 138 adult patients (age>18 years), who underwent a simple laminectomy for lumbar stenosis between 2011 and 2012. CSF leakage was the main outcome variable. Patients' wounds were examined for CSF leakage up to 1 week postoperatively. RESULTS: The incidence of pinhole type durotomy and subsequent CSF leakage in our region was 8.7%. Univariate analysis showed that hypertension, diabetes and smoking were significantly associated with durotomy and increased CSF leakage by 16.72, 44.25, and 33.71 times, respectively. Multivariate analysis showed that only smoking and diabetes significantly increased the chances of leakage. CONCLUSIONS: Glycemic control and cessation of smoking prior to a simple laminectomy procedure reduced the incidence of a dural tear. Larger clinical studies on this lethal complication are required.
