Dynamic function of the fibula. Gait analysis evaluation of three different parts of the shank after fibulectomy: proximal, middle and distal.

The purpose of this case study was to investigate the dynamic features of fibular movement to gait pattern by analyzing the gait of individuals with three different parts of the fibula resected. Gait analyses revealed that proximal fibula resection impaired knee stability, whereas distal fibula resection disturbed ankle kinematics significantly. Except a mild secondary quadriceps weakness, middle fibula resection did not cause a significant biomechanical disturbance on gait.

Leiomyosarcoma of the small intestine found within an inguinal hernia sac: a case report.

Inguinal hernias and intra-abdominal malignancy are both common phenomena and their co-existence cannot be rare. Colon carcinomas are reported to be the most common cause of both intrasaccular and saccular tumours (1) but the occurrence of small intestine carcinoma inside an inguinal hernia has not been reported. We describe the first case--a leiomyosarcoma of the ileum--which was also complicated by irreduction.

Isolated hydatid cyst of the breast.

Although common in sheep-breeding communities, hydatid disease is actually found worldwide. Man is an occasional intermediate host in whom the disease is manifested by the presence of one or more hydatid cysts, usually located in the liver or lung and rarely at other sites such as the breast, as in our patient. A case of an isolated breast involvement that was diagnosed during surgery is presented and is followed by a brief discussion on the topic.

Ectopic liver tissue attached to the gallbladder.

A 55-year old woman underwent cholecystectomy for cholelithiasis. The removed gallbladder showed a serosal encapsulated nodule, measuring 14 x 6 mm, that histologically was an ectopic functioning liver. This nodule had no connection with the main liver.

Repairing great duodenal defects in rabbits by ePTFE patch.

The aim of this experimental study was to evaluate the results of repairing large duodenal defects in rabbits by an ePTFE (Gore-Tex) soft tissue patch graft. A defect as large as 50% of the total circumference of the duodenum (i.e.
