Abstract Objective Normal cervical spine canal morphometry is critical for understanding the pathology of certain diseases and for proper preoperative planning. Computerized tomography (CT) scan can replace older conventional radiography techniques by providing more accurate morphometric measurements. This study was aimed to find out various dimensions of the cervical spinal canal of central Indian population. Materials and Methods A prospective study was conducted including 100 consecutive cervical spine CT scan of asymptomatic adult subjects. The anteroposterior sagittal canal diameter (SCD), transverse canal diameter (TCD), canal surface area (CSA), and Pavlov-Torg Ratio (PTR) from C2 to C7 were calculated. Statistical Analysis Data were entered in Microsoft Excel Sheet 2007 and statistical analysis was performed by IBM SPSS statistics 2.0 version. p-Value < 0.05 was considered as significant. Results Age ranged from 18 years to 77 years with mean age 39.5 years. There was no significant difference in all the dimensions (SCD, TCD, CSA) in male and female except at C2 level, where SCD, TCD, and CSA were significant larger in male. The mean SCD, TCD, and CSA is largest at C2 level (14.4 ± 1.63 mm, 21.57 ± 1.59 mm, and 156.20 ± 24.98 mm2, respectively) and smallest at C4 level (12.77 ± 1.48 mm, 20.37 ± 1.72 mm, and 130.42 ± 21.20 mm2). PTR showed very little variation. Conclusion Normal values of cervical spinal canal could serve as a future reference. CT scan provides more accurate measurement. More studies are needed as there could be variations in dimensions in different regions in India.

Background: Manipulation during endotracheal intubation in patients with craniovertebral junction (CVJ) anomalies may cause neurological deterioration due to underlying instability. Fiberoptic-bronchoscopy (FOB) is better than video laryngoscope (VL) for minimizing cervical spine movement during intubation. However, evidence suggesting superiority of FOB in patients with CVJ instability is lacking. We prospectively compared dynamic movements of the upper cervical spine during intubation using FOB with VL in patients with CVJ anomalies. Methods: A prospective, randomized, and clinical trial was conducted in 62 patients of American Society of Anaesthesiologist Grade I-II aged between 12 and 65 years with CVJ anomalies. Patients were randomized for intubation under general anesthesia with either VL or FOB. The intubation process was done with application of skeletal traction and recorded cinefluroscopically. The dynamic interrelationship of bony landmarks (horizontal, vertical, and diagonal distances between fixed points on posterior C1 and C2) was analyzed to indirectly calculate alteration of the upper cervical spinal canal diameter (at CVJ). Atlanto-dental interval (ADI) was calculated wherever possible. Results: The alteration in canal diameter (using bony landmarks) at CVJ during intubation was not significant with the use of either VL or FOB (P > 0.05). In 41 patients, where ADI could be measured, ADI was reduced (increased spinal canal diameter) in a greater number of patients in VL group when compared to FOB group (P < 0.05). Conclusion: Using rigid skull traction, intubation under general anesthesia with VL offers similar advantage as FOB in terms of the spinal kinematics in patients with CVJ anomalies/instability. Nevertheless, greater number of patients intubated with VL may have an advantage of increased cervical spinal canal diameter when compared to FOB.

Background: Detailed knowledge of cervical canal and transverse foramens’ morphometry is critical for understanding the pathology of certain diseases and for proper preoperative planning. Lateral x-rays do not provide the necessary accuracy. A retrospective morphometric study of the cervical canal was performed at the authors’ institution to measure mean dimensions of sagittal canal diameter (SCD), right and left transverse foramens’ sagittal (SFD) and transverse (TFD) diameters and minimum distance between spinal canal and transverse foramens (dSC-TF) for each level of the cervical spine from C1-C7, using computerized tomographic scans, in 100 patients from the archives of the Emergency Room. Results: Significant differences for SCD were detected between C1 and the other levels of the cervical spine for both male and female patients. For the transverse foramen, significant differences in sagittal diameters were detected at C3, C4, C5 levels. For transverse diameters, significant differences at C3 and C4 levels. A significant difference of the distance between the transverse spinal foramen and the cervical canal was measured between left and right side at the level of C3. This difference was equally observed to male and female subjects. Conclusion: CT scan can replace older conventional radiography techniques by providing more accurate measurements on anatomical elements of the cervical spine that could facilitate diagnosis and preoperative planning, thus avoiding possible trauma to the vertebral arteries during tissue dissection and instrument application.

Background/Aim. A modern approach to surgical treatment of tuboperitoneal infertility is based on laporascopic techniques. The aim of this study was to compare results of tuboperitoneal infertility treatment by the use of laparoscopy and classical laparotomy. Methods. A retrospectiveprospective study on 66 women treated operatively form tuboperitoneal infertility was performed. Data from patient's anamnesis and those related to the surgical treatment results, obtained by the use of an inquiry, were used in retrospective and prospective analysis, respectively. Chi-square test was used in statistical analysis. P value < 0.05 was considered significant. Results. Classical laparotomy was used on 34 women in a period from 1996 to 1997, while 32 women were operated laparoscopically in a period from 1999 to 2000. The results were as follows: a total number of conceived women was 16 (24%), seven in the group I (20.6%) and nine in the group II (28.1%); 13 women were with one pregnancy, six in the group I (17.6%) and seven in the group II (22%). Twice pregnant were three women, one in the group I (2.9%) and two in the group II (6.2%). The resulting pregnancies were: five women with abortion spontaneous, two in the group I (5.9%) and three in the group II (9.4%); two women with extrauterine pregnancy in the group I (5.9%); three with pretemporal birth, one in the group I (2.9%) and two in the group II (6.2%), while six women were with the temporal birth, two in the group I (5.9%) and four in the group II (12.5%). Statistical analysis showed that there was no significant difference in the results between these two groups. Conclusion. Surgical treatment of tubeperitoneal infertility, regardless of the used methods (classical laparotomy or laparoscopy) was successful in a great number of women. These methods have a great advantage over in vitro fertilization, and they should not be ignored.

Abstract ObjectiveTo evaluate the value of intraoperative CT scanning in the treatment of fresh thoracolumbar burst fractures .MethodThe data of patients with thoracolumbar fractures from January 2008 to January 2015 were analyzed retrospectively,79 cases were treatment group which were treated with intraoperative CT scan and decompression mode was determined according to CT scan results during the period from October 2012 to January 2015; 82 patients as the observation group were treated without intraoperative CT scan and direct laminectomy were performed during the period from January 2008 to October 2012. In the treatment group, it is no further decompression of the spinal canal when the CT showed a reduction of the fracture block into the spinal canal, If the intraoperative CT showed that the fractures still occupied the spinal dura mater according to the three-dimensional CT information, The position and the size of the fracture of the spinal canal were determined, and the unilateral laminectomy was performed corresponding to the position of the lamina and intervertebral ligamentum flavum. The operative time, bleeding volume, neurological function, height of the anterior vertebral compression and Cobb angle were compared between the two groups.ResultIn the treatment group, CT scan showed 48 cases (60.8%) entered the spinal canal fracture completely or basically reset .31 cases (39.2%) still occupied the spinal canal compression spinal dura mater. There were significant differences in the operation time and bleeding volume between the two groups. The treatment group was less than the control group. There was no infection, secondary spinal cord injury, loose fixation and other complications. There was no difference in the ASIA classification before and after operation. The anterior vertebral height and COBB angle of the two groups were significantly improved compared with those before operation. There was no significant difference between the two groups in the postoperative height and COBB angle, but after 2 years the difference was statistically significant between the two groups, to retain the rear ligament complex treatment group was significantly better than the control group.ConclusionPatients of thoracolumbar vertebral fracture in hyperextension position combined with internal fixation can achieve good correction effect. Orthopedic postoperative CT scan and according to the results of the scan precision treatment can simplify the operation, there was no difference in clinical efficacy compared with total laminectomy, but some patients avoid the spinal canal decompression and part were treated by small fenestration laminectomy decompression, which is conducive to the protection of spinouts ligament complex integrity.
