Background: The occurrence of vertebral fractures and spinal cord injuries in developing countries in Africa is high with an annual incidence rate of 12.1 to 57.8 per million; 82.8% of these occurring in males and the most common causes being vehicle crushes (41.4%) and falls (34.9%)1. Treatment of vertebral fractures is aimed at stabilising a segment and then restoring its mobility thereby preventing nerve damage2. Violation of the pedicle walls during transpedicular screw fixation may occur if the screw diameter is too large or there is wrong placement3. Prevalence of pedicle wall violation using the “free hand” technique was reported to be 1.4%4. Objective: To document the dimensions of the pedicles of lumbar vertebrae in the Zimbabwean population. Study design: A descriptive cross-sectional study. Place and duration of study: The study was conducted in the Gross Anatomy Laboratory of the Department of Anatomy, University of Zimbabwe College of Health Sciences, Harare. The duration of study was 6 months (from June 2019 to December 2019). Material and Methods: A total of 15 adult male cadaveric specimens were taken from the Department of Anatomy at University of Zimbabwe. The lumbar vertebrae were dissected and their Pedicle Transverse Diameter (PTD), Pedicle Vertical Diameter (PVD) and the chord length were measured using a vernier calliper. Statistical calculations were performed using SPSS version 20. Results: There was no significant difference between the pedicle dimensions of the right and left sides (P > 0.05). PTD steadily increases from vertebral level L1 to L4 followed by an abrupt increase at L5. PVD gradually decreases from L1 to L5 level. The chord length increases from a minimum at L1 to reach a maximum at L3 and then again decreases to L5 level. Conclusion: Pedicle dimensions for the Zimbabwean population differ from those reported in previous studies for other population groups. Key words: Chord length, Lumbar vertebrae, Pedicle dimensions.

ObjectiveGH deficiency (GHD) and glucocorticoid excess are associated with increased risk of fragility fractures. We aimed to evaluate whether the prevalence of vertebral fractures may be influenced by glucocorticoid over-replacement in hypopituitary males with GHD.DesignCross-sectional study.MethodsFifty-one adult hypopituitary patients (all males; mean age 55 years, range: 23–81) with severe adult-onset GHD (replaced in 21 patients and untreated in 30 patients) and glucocorticoid deficiency on replacement treatment were studied for vertebral fractures using a radiological and morphometric approach.ResultsVertebral fractures were observed in 31 patients (60.8%) in correlation with untreated GHD, urinary cortisol values, and cortisone doses. Patients were stratified according to treatment of GHD, and current and cumulative cortisone doses. In untreated GHD, vertebral fractures occurred more frequently in patients who had received higher (greater than median) cumulative and current doses of cortisone compared with patients who had received lower (less than median) drug doses (95.2 vs 50.0%, P=0.009 and 90.5 vs 55.6%, P=0.04 respectively). In untreated GHD, fractured patients had significantly higher urinary cortisol values compared with patients without vertebral fractures (84 μg/24 h, range: 24–135 vs 49 μg/24 h, range: 30–96; P=0.04). In treated GHD patients, by contrast, the prevalence of vertebral fractures was not influenced by cumulative and current cortisone doses and urinary cortisol values.ConclusionsGlucocorticoid over-replacement may increase the prevalence of vertebral fractures in patients with untreated GHD. However, treatment of GHD seems to protect the skeleton from the deleterious effects of glucocorticoid overtreatment in hypopituitary patients.

Anthropologic parameters of the spleen are important because many diseases present with reduction or enlargement of the spleen. No data exists about the standard dimensions of the normal spleen in Iranian population. Therefore, the objective of the study was to investigate anthropologic parameters of the spleen in Iranian cadavers.  In 2014-2015, this cross sectional study was undertaken from the Razavi Khorasan Province of Iran. Iranian cadavers (n=693, 152 female/541 male) with no history of poisoning, drug or alcohol addiction, no gross abnormality and injury of the spleen were included in the study. The length, width and thickness of spleen were measured using a Vernier caliper. The mean values of the demographic data were age= 40.28 ± 20.97 years; weight = 63.68 ± 17.40 kg; height = 160.03 ± 28.45 cm and BMI = 25.03 ± 20.46 kg/m2. The mean values of the spleen length, width, thickness, notch, weight and index in the cadavers were 11.32 ± 3.10 cm, 8.05 ± 2.35 cm, 20.12 ± 9.21 mm, 0.84 ± 1.35, 123.87 ± 82.46 g, and 2.01 ± 1.40, respectively. Accessory spleen was found in five cadavers. The anthropologic parameters of the spleen showed significant difference between males and females except for index of the spleen.  Having standard data on the spleen is useful for radiologists, surgeons, anatomists and anthropologists. The results of the study may provide valuable data in the standardization of the anthropologic parameters of the spleen in the Iranian population.

Background: It is observed that the morphologic and morphometric variability of the occipital bone structures may coexist in the same individual or among different subjects of the same or different populations and thus, a sound knowledge of the morphometry of this area can provide important benefits in determining safe surgical zones during surgical procedures. Aim: The present study was aimed at measuring the length (right and left) and width (right and left) of the hypoglossal canal among adult dry skulls of two states in southern Nigeria. Materials and Method: This study adopted the cross sectional study design. A total of eighty (80) hypoglossal canal; right and left were selected by simple random sampling and their length and width were measured with the aid of the digital vernier caliper. Results: The hypoglossal canal length on the right side was seen to be higher compared to the left length of the hypoglossal canal while the right hypoglossal canal width was seen to be higher compared to the left hypoglossal canal width and also observed differences between the right and left sides were statistically significant (P=0.01). Conclusion: There was a statistical significant difference with regard to hypoglossal canal length (right and left) and width (right and left) among the studied population.

Introduction: Digit ratio (2D:4D) has been associated with cardiovascular diseases using association with surrogate markers. Studies showing an association of digit ratio with cardiovascular parameters within normal limits are scarce. Aim: To explore the relation between different blood pressure components and digit ratio in normal young males within physiological range. Materials and Methods: In this cross-sectional pilot study, 25 apparently healthy male volunteers were included. Digit ratio (2D:4D) was measured. Body Mass Index (BMI) was estimated. Peripheral blood pressure, central aortic blood pressure and all four limb blood pressures were measured using periscope arterial health and cardiovascular analysis system. Blood pressure was measured using oscillometric method from all peripheral sites and estimated central aortic pressure by a validated transfer function. Pearson’s correlation studies were performed to assess any preliminary association. Two groups were formed of low and high digit ratio and Student’s t-test was performed to assess any significant difference between the groups. Results: Digit ratio of both hands correlated best with peripheral Diastolic Blood Pressure (DBP) (Right 2D:4D r=0.43, p<0.05/Left 2D:4D r=0.40, p<0.05). No significant association observed for peripheral systolic pressure (p>0.05) and digit ratio of both hands. Significant association observed for all four limb blood pressure components and digit ratio. Pulse pressure components did not show any association with digit ratio. Significant difference of blood pressure components was observed when low and high digit ratio groups were compared. It was observed that blood pressure components were on higher side within the normal limits among the subjects with high digit ratio. Conclusion: Preliminary observations from this pilot study suggests that in normal young adult males digit ratio associate positively with different blood pressure components in normotensive males and has the potential to be used as a potent marker for early changes in cardiovascular diseases.

Background: The vertebral column is the central pillar of the body which has cervical, thoracic, lumbar, sacral and coccygeal parts. Out of these, the lumbar part is made up of five lumbar vertebrae which lies between the thoracic part above and the sacral part below.  Objective: The study aimed to measure pedicle dimensions of lumbar vertebrae by using computed tomography scan. Methodology: This is a descriptive cross-sectional study which was conducted on 115 images of computed tomography scan collected from the Department of Radio-Diagnosis, Dhulikhel Hospital between May and October 2019 after receiving ethical approval from the Institutional Review Committee. All the scans available in the department were taken for the study. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. Data analysis was done in the Statistical Package for the Social Sciences version 16 (SPSS 16.0). Results: The pedicle chord length and breadth progressively decrease from L1 to L5 vertebral levels and pedicle thickness gradually increases from L1 to L5 vertebrae on both sides in both genders. The pedicle chord lengths were found significantly different whereas breadth and thickness were insignificantly different between males and females at all lumbar vertebral levels except at L1 for breadth. Conclusions: The pedicle chord length and breadth gradually decreases whereas thickness increases from L1 to L5 vertebral levels amongst Nepalese population.

: Knee deformities can be reliably assessed by using morphometric parameters of upper end of tibia. Total knee arthroplasties are done to treat many types of arthritis and injuries involving knee joint. So, there is a need to have data of various morphometric parameters of upper end of tibia in order to have better surgical outcomes. The present study was attempted to provide values of different parameters in the population of Bihar.: The present study was a cross-sectional and prospective study conducted on 50 tibia of unknown gender and age in the Department of Anatomy, Indira Gandhi Institute of Medical Sciences, Patna. Fully ossified, dried, macerated and thoroughly cleaned tibia were taken to measure different parameters of upper end with the help of digital vernier calliper. The data thus obtained were tabulated and analysed statistically using Microsoft excel software.: It was found that the diameters of medial condyle were more than the lateral condyle. The antero-posterior diameter was more than the transverse diameter in case of both the condyles. But the difference between the right and the left side was not statistically significant.: The present study will help in providing a baseline data for designing of the prosthesis used in total knee replacement surgeries. It will also be helpful to anthropologists and forensic experts.

Background: By assessing the size of the foramen magnum, it is possible to distinguish two genders, as well as the intergenerational interdependence of the affected individuals. The present study aimed at assessing the value of diameters of foramen magnum for gender identification among the Iranian population.Methods: This analytical comparative cross-sectional study was performed on 200 Iranian cadavers (100 men and 100 women) referred to Kahrizak Autopsy Hall in Tehran between 2017 and 2018. In each case, the foramen magnum was measured by observation and its parameters were measured in a longitudinal anteroposterior and transverse diameter, using a calibrated caliper.Results: The Mean±SD anterior-posterior diameter of the foramen magnum in men and women were 35.59±0.49 mm and 33.90±1.07 mm, respectively, which was significantly higher in men (P<0.001). Similarly, the Mean±SD transverse diameter of the foramen magnum in males and females was 29.49±0.56 mm and 28.5±0.50 mm, respectively, which was significantly higher in men (P<0.001). Based on the area analysis under the Receiver Operating Characteristic (ROC) curve, the anterior-posterior and transverse diameters of the foramen magnum had a high value in the differentiation of the male and female genders (AUC=0.953 and 0.896, respectively, P<0.001). The Mean±SD foramen magnum index in men and women was 84.15±3.02 and 82.87±1.95, respectively, which had a significant difference between the two genders.Conclusion: Given that the anterior-posterior and transverse diameters of the foramen magnum in Iranian men are far more than Iranian women, these diameters can be used to distinguish between the two genders in the precise legal field.

SummarySheep are frequently used as animal models in experimental spinal injury studies. Therefore, extensive knowledge of ovine spinal dimensions is essential for experimental design and interpretation of results obtained in these trials. This study aimed to obtain quantitative morphometrical data of the thoracolumbar dural sac in sheep and determine the anatomical relationship between the dural sac and the vertebral canal.Computed assisted myelography imaging was carried out in five adult German Black-Headed Mutton sheep under general anaesthesia. Transverse images were acquired with 2 mm slice thickness from the first thoracic to the sixth lumbar vertebrae. Sagittal and transverse diameters and the cross-sectional area of the dural sac and vertebral canal were measured. To determine the anatomical relationship between the dural sac and vertebral canal, the pedicledural sac distance (PPSD) and the epidural space as well as the SAC (available space for the dural sac) were calculated.Sagittal diameters of the dural sac ranged from 5.1 to 12.0 mm. Transverse diameters ranged from 5.6 to 12.2 mm. The dural sac area covered 45.9% and 49.0% of the thoracic and lumbar vertebral canal area. The PDSD in the lumbar vertebrae was up to 15.8% larger than in the thoracic ones. The dural sac area was significantly positively correlated with the transverse diameter and area of the vertebral canal.The lumbar vertebral canal contained more space for the dural sac, which seems to be safer for testing spinal implants.

Introduction: Radius is the lateral bone of forearm. Important parameters of its distal end include angle of radial inclination, palmar tilt, and length of radial styloid process. Morphometry of the distal end of radius is important in various clinical orthopaedic procedures such as reduction of distal radius fractures, design of distal radius prosthesis, and kinematics of the wrist joint. The aim of this study is to determine the angle of radial inclination, palmar tilt, length of styloid process, oblique width, transverse and anteroposterior diameter of distal end of human dry radii in Nepalese population. Methods: This is a descriptive cross-sectional study conducted in the dissection hall of Department of Human Anatomy, Nepalese Army Institute of Health Sciences, Sanobhyrang, Kathmandu, Nepal from October 2019 to November 2019 after obtaining ethical approval. Total 76 human dry radii were included in the study by convenience sampling method. Angle of radial inclination, palmar tilt, length of styloid process, oblique width, transverse and anteroposterior diameter of distal end of human dry radii were studied. Data was collected and analysed by SPSS version 24. Results: Mean length of styloid process was 1.09 cm. Mean anteroposterior and transverse diameter of distal end of radius was 1.88 cm and 2.85 cm respectively. Mean oblique width of distal radius was 2.82 cm. The mean palmar tilt and angle of inclination of radius were 9.72 and 23.62 degree respectively. Conclusions: This study provides the reference data for the anatomical alignment while treating the injuries of the distal end of radius in Nepalese population.

Background: Morphometric knowledge of the sternum is of great significance in cardiac surgery as variations in sternal dimensions have been considered a risk factor for translocation of suture material during median sternotomy, leading to poor outcomes. Fatalities attributed to subnor- mal sternal thickness have also been reported during sternal biopsies. Fractures of the sternum secondary to chest injury or cardio-pulmonary resuscitation may also be influenced by sternal thickness. Elongated xiphoid process can be mistaken for an epigastric mass which can be painful on palpation. Morphometric studies of African sterna are rare. The objective is to the study sought to describe the morphometry of adult sterna from the Galloway bone collection, Makerere University, Kampala, Uganda. Subjects and Methods: This study employed a descriptive cross sectional design to collect and analyze quantitative data. Eighty five dry adult sterna (75 males and 10 females) were examined at the Department of Human Anatomy, Makerere University. Data analysis at univariate and bivariate levels were performed using SPSS version 21.0 statistical software. Results:A significant difference in the average length of the mesosternum was found between males at 94.6 mm (SD 11.2) and females at 82.2 mm (SD 15.2) (P=0.002). Two cases (9.5%) presented with elongated xiphoid process and one (1.2%) with subnormal mesosternal thickness. Conclusions: Our study highlights the importance of knowledge of the sternal morphometry in sex identification, physical examination, sternal puncture and other thoracic procedures, calling for increased awareness of the findings.
