We reviewed thrity-one cases of unstable tibial fractures treated with Ilizarov method from January 1991 to December 1992. We attained satisfactory bony union in all cases without bone graft(Average time 19.2 weeks). There were numbers of complications, but its were soluble and careful management & numbers of minor surgery were needed to prevent & solve such complications. Post-op immediate weight bearing and ROM exercise were possible and showed no difficulty in getting mainteance of reduction & fracture healing, and serious joint ankylosis was not developed. In conclusions, Ilizarov method is an excellent treatment in getting reduction, maintenance of reduction, early ambulation and fracture healing in the cases of unstable tibia fractures.

Traumatic atlanto-occipital dislocation is usually fatal. To date, few cases have been reported in the literature because survival after traumatic atlanto-occipital dislocation is extremely rare. We present the case of a 47-year-old man with traumatic atlanto-occipital rotatory posterior dislocation combined with atlanto-axial rotatory subluxation and treated by occipito-cervical fusion using Bohlman's triple wiring technique.

An erectiometer for the measurement of sleep erections is described. Clinical data using the erectiometer indicates that it processes a significant potential for valid measurement of the circumfernetial increase that may occur during sleep. Because of its reliability, simplicity, reproducible data and low cost the erectiometer is proposed as a screening procedure or as a diagnostic alternative when sleep laboratory facilities are not feasible practically.

Spinal epidural hematoma is a rare complication of epidural anesthesia and most commonly associated with intraoperative or postoperative anticoagulant administration. We describe the case of an acute thoracolumbar epidural hematoma at the T12-L4 level complicated by cauda equina syndrome, which occurred after placement of spinal epidural catheter for anesthesia and anticoagulant therapy for acute myocardial infarction developed postoperatively. In our experience, the spinal epidural catheterization and anticoagulant therapy may potentially increase the risk of epidural hematoma formation.

The effect of acetabular augmentation with bone graft was reviewed in 12 patients with acetabular deficiency in total hip arthroplasty, performed between 1981 and 1984 at Hanyang University Hospital. Follow-up ranged from 12 to 18 months and averaged 23.3 months. Follow-up radiographs were analyzed. Based on radiography, all grafts were regarded as incorporated and equally successful with autogenous and allograft bone. Long-term follow-up evaluation revealed no evidence of progressive radiolucency or graft resorption. There was one sciatic nerve palsy after operation but recovered at 11 months later.

A case of nonfunctioning pancreatic islet cell tumor is described. A 34 years old female patient had intermittent epigastric pain and nausea for 6 months and she had nothing suggestive of neuroendocrine symtoms. Physcial examination showed an epigastric mass which wae deepseated, nontender, and well-demarcated. The routine upper endoscopic evatuation was negative. Abdominal ultrasonography and computed tomography showed a well-defined round solid mass with multifocal necrosis but did not revealed the origin of the lesion. Endoscopic retrograde pancreatography showed upward and rightward displacement of the proximal body portion of main pancreatic duct with nonvisualization of the secondary branches of pancreatic duct, suggesting that the mass originated from the pancreas. Resection of the mass with partial pancreatectomy and Roux-en-Y pancreaticojejunostomy was perfomed and the pathology was coafirmed as nonfunctioning pancreatic islet cell tumor containing somatostatin by immunohistochemical technique.

Objectives: The purpose of study is to evaluate serial MR imaging of myocardial infarction using non-surgical model of myocardial infarction after percutaneous transcatheter coronary arterial embolization in dogs. MATERIALS AND METHODS: We evaluated serial pre- and post-contrast MR images with Gd-DTPA (gadolinium-diethylenetriamine-pentaacetic acid) of heart of the eleven mongrel dogs (immediate group (n=3), one week group (n=3), three weeks group (n=5)) after making non-surgically induced myocardial infarction. We confirmed the infarct with TTC staining and microscopically. The location and extents of the myocardial infarction were correlated. RESULTS: A total of 24 MR images were archived; 11 images of the immediate post-embolic period, 8 images of one-week follow-up, and five of 3-week follow-up images. Comparing with the signal intensity of normal myocardium, immediate post-embolic MR images showed low or iso signal intensities (SI) of the infarct area on T1-weighted images (T1WI) and high SI on T2-weighted images (T2WI). No contrast enhancement with Gd-DTPA was made in all cases of the immediate post-embolic MRI. One-week and 3-week follow-up MR images showed low or iso SI on T1WI and slight high or iso SI on T2WI. Contrast enhancement images in both one-week and 3-week follow-up MRI showed denser enhancement of infarct area in one-week follow-up. The myocardial wall thinning was seen in 5 of eight dogs after one week and in 3 of five after 3 weeks. CONCLUSION: In non-surgical animal models of myocardial infarction, MR images showed low or iso SI on T1WI, and high SI on T2WI in various stages, and contrast enhancement was maximum after one week and gradual decrease to 3 weeks. The myocardial wall thinning was seen in one-to 3-week follow-up MR images.
