Background: Transpedicular fixation depends on accuracy of the entry points, angle of insertion and pedicular isthmus width for adequate screw insertion. Preoperative measurements of pedicle dimensions reduce the chances of failure during insertion. These pedicle dimensions (transverse diameter, longitudinal diameter, and maximum length of purchase [MLP]) vary with sex and race. Such data, from a large-scale study, are not available for our population. Objective: The study aims to evaluate the dimensions of pedicle that are relevant for pedicle screw fixation in Southeast Nigerian population. Materials and Methods: A prospective multi-slice CT based clinical anatomy study done at Memfys Hospital for Neurosurgery, Enugu. This study is on the lumbar pedicle dimensions that are related to transpedicular fixation (transverse and longitudinal diameters of the pedicle, MLP, pedicle transverse and longitudinal angles of inclination). Sample size (273) was calculated with the confidence interval formula based on the number of patients that present for images. Consent and ethical approval were obtained. Results: The mean values are as follow: LD1 8.22 mm, LD2 7.73 mm, LD3 7.40 mm, LD4 7.16 mm, LD5 6.87 mm TD1 5.05 mm, TD2 5.31 mm, TD3 6.72 mm, TD4 8.27 mm, TD5 11.31 mm, MLP1 46.60 mm, MLP2 47.97 mm, MLP3 47.14 mm, MLP4 45.54 mm, MLP5 43.47 mm TA1 17.8°, TA2 19.34°, TA3 20.80°, TA4 22.00°, TA5 25.70° LA1 19.42°, LA2 18.61°, LA3 18.00°, LA4 17.09°, LA5 16.40°. Unlike transverse diameter, transverse angle, longitudinal dimension, longitudinal angle (LA), MLP there was significant correlation between age and mean LA. The mean values also correlated significantly with the gender. Conclusion: The mean values varied with the different vertebral levels and was good correlations between some of the parameters with age and gender. [ABSTRACT FROM AUTHOR]

Liponeurocytoma is a newly defined clinical entity predominantly seen in the cerebellum as a slow-growing tumor. In this report, we present the case of a 6-year-old Nigerian girl with a liponeurocytoma, and review of literature. [ABSTRACT FROM AUTHOR]

Spine conditions are common and the surgery is evolving even in developed economies. This study aims to review the changing trends and challenges of spine surgery, particularly from a low-income country. This is a retrospective study of patients who were surgically treated for spine conditions in Enugu, Nigeria. Patient records from 2006 to 2016 were reviewed. Relevant clinical information was extracted from the operation theater logbooks and patient case files. A total of 463 spine surgical procedures were carried out on the same number of patients. The number of treated patients has been on the increase and shows a male predominance. Pediatric spine cases accounted for 1.5%, adult/middle aged patients accounted for 77.8%. Degenerative conditions, trauma, and neoplasms were the most frequent indications for operation, accounting for 52.3%, 30.5%, and 11.4%, respectively. The most commonly operated region was cervical and lumbar regions among male (49.3%) and female (51.8%) patients, respectively. Spine fixation was required in 137 patients (29.6%). A paradigm shift from trauma to degenerative conditions among patients was noted after 2010. Prior to 2009, spine wiring techniques were the most common spine stabilizing method, but from 2011 to 2013 anterior cervical discectomy and anterior cervical discectomy and fusion predominated, and thereafter pedicle screws predominated. Cost implications, lack of trained personnel, and lack of and basic equipment pose significant challenges to spine care. The trend in spinal surgery has improved rapidly and consistently in Nigeria over the 10 years of the study and is related to increasing expertise, more available facilities, and implant availability.
