Introduction: Cervical laminectomy is a very well-known posterior decompressive procedure for cervical compressive myelopathy (CCM). Our objective is to evaluate the functional effect of posterior decompressive laminectomy for poor grade CCM. Methods: This study was an observational retrospective study carried out on patients with poor-grade CCM who underwent decompressive laminectomy from January 2010 to December 2015. Patients with Nurick Grades 4 and 5 (walking with support or bedbound) were included in the study. Clinical data and radiological information were collected from medical records, and objective scales were applied to compare the surgical outcome between preoperative score and postoperative score. Results: A total of 69 patients who underwent decompressive laminectomy for poor grade CCM were included. The mean age was 54.9 years, and the male-to-female ratio was 5.3:1. Ossified posterior longitudinal ligament comprised 52.6% cases. The follow-up data of at least 6 months' duration after surgery was available for 57 (82.6%) cases. On comparing with preoperative Nurick grade at follow-up, 40 of the 57 patients (70.2%) were found to have improvement following surgery by at least one grade. The remaining 17 (29.8%) had either remained the same or had deteriorated further. The mean preoperative modified Japanese Orthopedic Association score was 8.4 ± 2.8, and the mean follow-up score was 11.8±0.3 (P = 0.0001). On multivariate analysis, the number of levels of laminectomy, postoperative deterioration, and anesthesia grade were predictors of outcome. Conclusion: Decompressive laminectomy for poor grade myelopathy is effective in improving functional outcome.

In an international trial involving 450 patients with acute subdural hematoma, craniotomy (bone flap replaced) and decompressive craniectomy (bone flap left out) yielded similar disability-related outcomes at 12 months.

Background: Decompressive craniectomy (DC) is a rescue operation performed for reduction of intracranial pressure due to progressive brain swelling, mandating the need for cranioplasty. Objective: To describe expansile craniotomy (EC) as a noninferior technique that may be effectively utilized in situations requiring standard DC. Materials and Methods: A decision to perform DC or EC was taken by consecutively allocation to either of the procedures. The bone flap was divided into three pieces, which were tied loosely to each other and to the skull using silk threads. The primary outcome included functional assessment using Glasgow outcome scale (GOS) score at 1 year. Results and Conclusions: Total 67 patients were included in the analyses, of which, 31 underwent EC and 36 underwent DC. Both the cohorts were matched in terms of baseline determinants for age, Glasgow coma scale, and Rotterdam score at admission. There was no significant difference in GOS scores and the extent of volume expansion obtained by EC as compared to DC. Complication rates though less in EC group did not differ significantly between the groups. EC appears to be the safe and effective alternative to DC in the management of brain swelling due to TBI with a potential to obviate the need of cranioplasty.

There are only a few case reports comprising exclusively of os omovertebrale. Here, we discuss various types, varied clinical presentations, associated abnormalities, and management strategies of this abnormality. We retrospectively analyzed three patients with os omovertebrale and their clinical presentation, and also reviewed the limited available literature. Patients were evaluated clinically and radiologically to diagnose this abnormality as well as the associated abnormalities. Two patients were operated for neurological deficits attributed to this deformity. It is quite common to miss this abnormality when it is of osseocartilaginous or fibrous type, especially when it is asymptomatic and not associated with Sprengel's scapula. By analyzing our patients and other reported cases, we have proposed a classification system. In addition, we discuss varied clinical presentations and their practical application. Os omovertebrale is a rare abnormality. It should be kept in mind and managed when encountered in clinical practice. The classification and clinicoradiological correlations described here can be useful to individualize management issues.

Context: Experience with elderly pedestrian neurotrauma at a major neurotrauma tertiary center. Aims: To highlight the specific injuries and outcome of the elderly pedestrian neurotrauma patients within the city of Bangalore and its surrounding districts. Settings and Design: A retrospective study consisting of demographic data, clinical findings, radiological details, and outcomes. Materials and Methods: A study was conducted at the casualty services, in which 143 consecutive elderly pedestrian (age >60 years) head injury victims were studied from June to September 2009. The records from the hospital mortuary were analyzed from 2007 to 2009. An analysis of 77 elderly patients who died as a pedestrian in accidents during this period was performed. Statistical Analysis Used: SPSS 15. Results: The elderly pedestrians constituted 27% (143/529) of all pedestrian traumas. Two wheelers were the most common accident vehicle (56.6%, 81/143). Most of the injuries (38.5%, 55/143) occurred during peak traffic hours, that is, 4 pm to 9 pm. Majority sustained moderate to severe head injury (61%, 87/143). More than three‑fourths of patients required a computed tomography (CT) scan (77%, 110/143), in which there was a higher frequency of contusion (31.5%, 45/143), and subdural hemorrhage (23.1%, 33/143). Most of the injured (43.3%, 13/30) underwent surgery for intracranial hematoma. The mortality rate was 22.8% (8/35). Nearly one‑fourth of conducted postmortems among pedestrians belonged to the elderly age group (77/326, 23.6%). Conclusions: Elderly pedestrian neurotrauma patients sustain a more severe injury as evident by poorer Glasgow Coma Score (GCS) scores and CT scan findings, and hence have a higher mortality rate.

Anterior communicating artery aneurysm rarely presents with symptoms of compression of anterior visual pathways. We report a case of 65 years old man, who had complete loss of vision in right eye and temporal hemianopsia in left eye due to giant anterior communicating artery aneurysm.

To the Editor: Hutchinson and colleagues (June 15 issue) 1 report that in patients with traumatic acute subdural hematoma, surgical evacuation by means of routine depressive craniectomy (in which the bone flap is not replaced) provides no outcome benefit over craniotomy (in which the bone flap is replaced). We are interested in clarification of some issues to assist in understanding the implications and generalizability of these results. The authors’ description of “too swollen” as a trial exclusion criterion without further detail (e.g., laterality of residual mass effect) is confusing with respect to the trial population. Was a “trial fit” maneuver (attempt . . .

Background: Fibrin glue as an adjunct in peripheral nerve injuries has gained recent popularity. Whether fibrosis and inflammatory processes which are the major hindrances in repair reduce with fibrin glue has more of theoretical support than experimental. Methodology: A prospective nerve repair study was conducted between two different species of rats as donor and recipient. Four comparison groups with 40 rats were outlined with or without fibrin glue in immediate post-injury period with fresh or cold preserved grafts were examined based on histological, macroscopic, functional, and electrophysiological criteria. Results: There was suture site granuloma along with neuroma formation and inflammatory reaction and severe epineural inflammation in allografts with immediate suturing (Group A), whereas suture site inflammation and epineural inflammation were negligible in cold preserved allografts with immediate suturing (Group B). Allografts with minimal suturing and glue (Group C) had less severe epineural inflammation with less severe suture site granuloma and neuroma formation as compared to first two groups. Continuity of nerve was partial in later group as compared to other two. In fibrin glue only group (Group D), suture site granuloma and neuroma were absent, with negligible epineural inflammation, but continuity nerve was partial to absent in most of the rats with some showing partial continuity. Functionally, microsuturing with or without glue demonstrated significant difference with better SLR and toe spread (p = 0.042) as compared with only glue. Electrophysiologically, NCV was maximum in Group A and least in Group D at 12 weeks. We report significant difference in CMAP and NCV between microsuturing group vs. only glue group (p < 0.05) and also between microsuturing with glue group vs. only glue group (p < 0.05). Conclusion: There may be more data required with proper standardization for adept usage of fibrin glue. Though our results have shown partial success, it nonetheless highlights the lack of sufficient data for widespread glue usage.

Background: A number of pharmacological agents have been tried to circumvent the problem of delayed cerebral ischemia (DCI) with ozagrel sodium being one such agent aimed at the prevention of DCI. Ozagrel is an inhibitor of thromboxane synthetase. It has anti-platelet aggregation action and it dilates vessels. Ozagrel was not available outside Japan till recently. It is available now in India and we had the opportunity to use it among patients with aneurysmal subarachnoid hemorrhage (SAH). Aims: To analyse the results of ozagrel administration for patients with aneurysmal SAH. Settings and Design: Tertiary care neurosurgical center. Materials and Methods: Retrospective analysis of the outcomes of patients who received ozagrel after microsurgical cllipping of aneurysm and comparison with a control grpup who received treatment as usual. Statistical Analysis: The t-test (two-tailed), Chi-square test, and Mann-Whitney U-test asymptomatic significance (two-tailed), were used respectively for continuous, categorical, and ordinal variables. The significance was determined at P = 0.05 level. Results: A total of 106 patients underwent surgical clipping of their ruptured intracranial aneurysms over a period of 22 months. Forty two (39.6%) patients received ozagrel, and 62 (60.4%) received the standard treatment. Ozagrel was started at a median of one [interquartile range (IQR) 0.75] day after the surgery, and was given for a median of five (IQR 5) days after the surgery. There was no difference in age, postictal days, World Federation Neurosurgical Society grade, Fisher grade, and the size of ruptured aneurysm in patients who received ozagrel compared to the patients who did not receive ozagrel. Of the 42 patients who received ozagrel, 30 patients (71.4%) had preoperative angiographic vasospasm which improved after the administration of ozagrel. Fifteen (35.5%) patients who received ozagrel developed delayed cerebral ischemia compared to only 11 (17.2%) patients who did not receive ozagrel. Thirty-six (85.7%) patients who received ozagrel had favorable outcome at discharge compared to 52 (81.3%) patients who did not receive ozagrel. No adverse event was observed with ozagrel therapy. At 3-month follow-up, 37 patients (88.1%) who received ozagrel had favorable outcomes against 53 patients (82.8%) who did not receive ozagrel. Conclusion: Ozagrel may be a useful drug in the armamentarium to treat vasospasm after aneurysmal SAH. A future multicenter large cohort study may validate the findings of our study.
