All clinical studies reported in the literature have indicated that non-operative treatment is the treatment of choice for the diaphyseal fractures of the clavicle. It has also been suggested by some that open reduction may contribute the development of nonunion. From 1985 to 1989, 23 of 133 diaphyseal fractures of the clavicle were treated by open reduction and internal fixation with the intramedullary pinning with or without cerclage wiring, or prebent plate and screw fixation with supplementary iliac bone graft in each instance. All fractures healed without any complication such as the infection, pin migration, other fixation failure, neurovascular accident, and pseudarthrosis. Based on our experience and review of the literature, we concluded that the indications for open reduction and internal fixation should be: 1. The patient's inability to tolerate prolonged immobilization or recumbency in multiple injury. 2. Widely distracted or displaced fractures in adults. 3. Comminution with one or more large butterfly fragments. 4. Neuro-vascular compromise due to displacement and impingement of the bone fragment. 5. Symptomatic delayed union or nonunion. 6. Refracture. And early operative treatment is safe, reliable and provide excellent results comparable to the conservative treatments.

Intramedullary nailing has become the most popular fixation method in the treatment of the shaft fractures of long bones especially of tibia and femur because it affords most rigid fixation of fracture via closed method which makes early rehabilitation possible. Nowadays intramedullary nailing of the humeral shaft is being performed by many surgeons with good results. Newer implants and better surgical techniques are being developed, which suggests application of this method can be widened. Purpose of this study was aimed to define whether intramedullary nailing could be an effective method or not in the treatment of humeral shaft fractures by documenting the practical points in the application of intramedullary nailing of humerus, effectiveness in fracture healing, any complications or obstacles. We managed thirteen humeral shaft fractures with closed locked intramedullary nailing with distal fanning devices(Seidel nail) from March 1993 to April 1994. Average follow-up period was 14 months(12 months-18 months). The results were as follows; 1, Union of the fracture was obtained at average 12.9 weeks(9 weeks-20 weeks) postoperatively except one case of nonunion, in which case, union was obtained at postoperative 10 months finally. 2. Among the 13 cases, painful limitation of shoulder motion remained in 6 cases. This complication was more common in the cases with protruded proximal end of the nail. Above results suggest that locked intramedullary nailing seemed to be one of the useful method in the treatment of the humeral shaft fractures. However, destruction and irritation of shoulder by the nail was found to be a grave problem, and we found that further investigations should solve this problem.

Neurofibromatosis is a complex hereditary disease involving many organs and systems. The incidence in pregnancy is less frequent and has been reported as 1/5000 to 1/18500 deliveries. Therefore, little is known about the interactions between neurofibromatosis and pregnancy. A survey of relevant literature suggests that patients with NF have an increased risk of perinatal complications (pregnancy induced hypertension, IUGR, preterm labor, abortion, stillbirth, high cesarean section rate) and maternal disease aggravation (rupture of an aneurysm, sarcomatous degeneration of neurofibroma, activation of pheochromocytoma). Refined ultrasound, flow studies and fetal monitoring allow us to provide improved pregnancy care for neurofibromatosis. However, It should be remembered that even now, neurofibromatosis places pregnant women and their fetuses in a high risk group with the potential to develop life threatening complications. We report a case of vertebral artery aneurysm and preeclampsia complicating a pregnancy with neurofibromatosis."

The purpose of this study was to investigate the morphologic changes of the bile canaliculi and its associated structures of the liver induced by common bile duct ligation(CBDL) in the rat. The canalicular surface and lateral surface of the dry-fractured hepatocytes was studied with scanning electron microscopy at 1~6 weeks post ligation. The first week after CBDL, the bile canaliculi were dilated. The microvilli were increased in number and the lumens contained granular materials After 2 weeks or more, the bile canaliculi were dilated to a variable degree, and with irregularity, measuring from 1.5 to 5 micrometer in diameter, and in the advanced stage, the canaliculi showed blunting and the disappearance of microvilli. Some canaliculi had sprouting side branches. At 4~6 weeks post-ligation, the lateral surface of the hepatocytes also showed some irregularity and a tortuous appearance, and numerous small sized microvillous projections were formed. The tubular structures of the proliferated SER distributed adjacent to the lateral surface of the hepatocytes, and the direct connection of a tubular structure and the cytoplasmic membrane was observed. These results suggest that the deformity and loss of microvilli of bile canaliculi reflect the disturbance of bile secretion from the hepatocytes. And prolonged obstruction of bile flow may result in bile excretion via the lateral surface of hepatocytes.
