ABSTRACT
The accessory navicular bone is a common and frequently unrecognized anomaly, but occasionally the source of pain over the instep of a flat footed person. Since the tibialis posterior tendons are attached to it and navicular bone, thus, the tendons of tibialis posterior were observed. A total of 388 feet (207 males and 181 females) were involved in this study. In each case, all tendons were symmetrical. There were 293 feet (75.5%) with two types of tendon attached to the navicualr bone; naked tendons were found in 188 feet (48.4%) and sesamoid cartilage or bones within the tendon wee found in 105 feet (27.1%). These two tendon types passed under the medical border of each foot. The tendons that were attached to accessory navicular bones were found in 95 feet (24.5%); as a separated bone, in 64 feet (16.5%) and as a prolongation inward (cornuate navicular), in 31 feet (8%). Among these tendons, the abnormal courses of tendons were found inward and upward displacement in parallel with the medial border of the feet. No significant difference was found according to the sex of these subjects (p = 0.254).
ABSTRACT
Common bile duct and main pancreatic duct of 89 Thai cadavers; 52 males and 37 females, were studied. Five types of the pattern of opening of common bile duct main pancreatic duct were found. The types which both ducts united to be hepatopancreatic duct before opening into the duodenal lumen were more common than the individual opening types, found in 61.8% and 35.95% respectivity. The rest was a special type which pancreatic duct divided into two channels : one channels : one channel joined common bile duct outside duodenum and the other joined the common bile duct in the wall of duodenum. The distribution of types in both sexes were not statistically significant difference. The length of hepatopancreatic duct varied from 1.3 to 11.95 millemeters.
