Diastematomyelia is a rare form of spinal dysraphism characterized by a sagittal cleft of varying extent in the spinal cord, conus medullaris or filum terminale with splaying of the posterior vertebral elements. This condition results from the presence of an osseous, cartilaginous or fibrous septum producing a complete or incomplete sagittal division of the spinal cord into two hemicords. It may be isolated or associated with other segmental anomalies of the vertebral bodies (1).

Background: Flexor digitorum brevis is an intrinsic muscle of the sole of foot that lies immediately deep to central part of plantar aponeurosis.The flexor digitorum brevis divided into four tendons for lateral four toes. Each tendon is divided into two slips at base of proximal phalanx, to allow the flexor digitorum longus tendons and get inserted on both sides of the shaft of middle phalanx. It helps to reinforce arch of foot by flexing the proximal interphalangeal and metatarsophalangeal joints of the lateral four toes. Flexor digitorum brevis muscular flap is used in the reconstruction of the heel pad and it is frequently used to correct crossover toe deformity so architecture of the foot is important because it may help in the surgical procedures during correction of above deformities.

Background: Variation in renal arteries are very common but bilateral variation is rare and is clinically important for urologist especially during the renal transplantation. Generally main renal artery divides into anterior and posterior branches just before entering the hilum of kidney, but sometimes two or more polar arteries; prehilar branching and segmental arteries arise from main renal artery .Renal artery variations are often seen and are generally categorized into presence of accessory or aberrant renal arteries, polar arteries and prehilar branches. Prehilar multiple branching of main renal artery variation is frequently seen. Materials and Method:The present study was conducted in 80 kidneys from 40 cadavers during the routine dissection in the Department of Anatomy Maharishi Markandeshwar Medical College and Muzaffarnagar Medical College .Out of 80 kidneys studied bilateral prehilar branching of renal arteries from the main renal artery were observed in 5 kidneys (6.5%). Conclusion:Different arterial branching patterns was observed in five cases in which prehilar branches originated directly from main renal artery, entering the upper pole of kidney. Knowledge of such variation is important for radiologists, anatomists and urologists while performing renal transplantation, laparoscopic renal surgeries, nephrectomies, and other renal surgeries and diagnosis.
