PURPOSE: We studied the diagnostic significance of bone scan in evaluation of bone metastasis by lung cancer, prevalence rate, and the causes of false positive bone scan and soft tissue accumulation of bone seeking agent. MATERIALS AND METHODS: The subject included 73 lung cancer patients with bone scan. We analyzed the frequency of bone metastasis, its distribution and configuration, and any relationship between bone pain and corresponding region on bone scan. The positive findings of bone scan were compared with simple X-ray film, CT, MRI and other diagnostic modalities. The false positive bone scan and the soft tissue accumulation of bone seeking agent were analized. RESULTS: The positive findings on bone scan were noted in 26 cases(36%) and they were coexistant with bone pain in 30%. The correspondance between bone scan and bone X-ray was 38%. False positive bone scans were seen in 12 cases(16%), which include fracture due to thoracotomy and trauma, degenerative bone diseases, and bifid rib. Accumulation of bone seeking agent in soft tissue were seen in 13 cases(18%), which included primary tumor, enlarged cervical lymph node, pleural effusion, ascites and pleural thickening. CONCLUSION: Bone scans should be carefully interpreted in detecting bone metastasis in primary malignancy, because of the 16% false positivity and 18% soft tissue accumulation rate. It is very important to note that the correlation between bone pain and positive findings of bone scans was only 38%.

Intracranial tumor with extracranial metastasis has been seldom reported. A 28 year-old-male was admitted to Presbyterian Hospital in Daegu on May 9, 1977. Who was diagnosed to have a medulloblastoma in the right cerebellar hemisphere with metastases to the right axillary lymphnode and head of pancreas by pathological reports. In generally medulloblastoma with extracranial metastasis occurs very rarely in the cerebellar hemisphere, and especially in adulthood. Distant metastasis of the intracranial tumor is discussed with review of the literatures.

Bone metastasis of hepatocellular carcinoma appears to be peculiar when clinical manifestation of liver disease is not apparent, and initial diagnosis of metastatic hepatocellular carcinoma by fine needle aspiration cytology is rarely obtained. We experienced a case of 45-year-old man with metastatic hepatocellular carcinoma in the sacrum, which was diagnosed by fine needle aspiration cytology. The intrahepatic mass, measuring 1.2cm in diameter and kept unchanged in size for two years, was never proved to be hepatocellular carcinoma histopathologically. The aspirated neoplastic cells were mostly in sheets, showing abundant acidophilic cytoplasm and large, round, centrally located nuclei with single, prominent acidophilic mucleoli. In the cell block section, diagnosis of metastatic well-differentiated hepatocellular carcinoma was made without difficulty, and definite trabecular fashion with sinusoidal endothelial cell lining was found.

12,688 cases of operative patients who received operation at kyungpook National University Hospital from Jul. 1977 to Dec. 1981 were analyzed according to each year, each surgical department, anesthetic technique, and the ratio of medical insurance patients after enforcement of medical insurance system. 1) Total operative patients were 12,688 cases including general patients 7,084 cases(54%) insurance patients 3,934 cases(31%), public assistance recipient 906 cases(7%), and industrial accident patients 764 cases(6%). 2) Total patients and insurance patients increased annually, while general patients decreased gradually. 3) Though regional and general anesthetic cases of general patients, decreased annually, those of insurance patients increased year by year. 4) Among the surgical department, the highest rate wwas neurosurgery 850 cases(73%) in general patients, E.N.T. 354 cases(54%) in insurance patinets, chest surgery 94 cases(17%) in public assistance recipient, and orthopedic surgery 350 cases(17%) in industrial accident patients. 5) E.N.T. department showed largest increase in insurance patients among surgical sections.

Recently, intramedullary nailing has been used classically in a closed transverse fracture in middle one-third of the fernur. But difficult femorsl fracture, such as severe comminution or nonunion, present a much more difficult problem. To treat these difficult femur fractures effectively, several investigators have developed and implemented a interlocking nail. Huckstep nail, one of the variants of the inter-locking nail, is a solid four sided intramedullary nail with screw fixation device and titanium alloy. For the purpose of rigid fixation and compression, screw fixation the nail and both cortice has been used in the difficult femorsl fractures. The author have experienced the 19 cases of Huckstep nailing for the treatment of difficult femoral fracture at the Choongahng Gil Hospital from Jan., 1984 to Dec., 1987. The results are summarized as follows. 1) In the difficult femoral fractures, such as fracture on severe comminuted fracture, nonunion and metal failure etc, Huckstep nailing may be excellent fixation. 2) Open comrninuted femoral frsctures were treated by conservative treatment as antibiotic therapy and skeletal traction, but when general conditions return to normal and risk of infection rate minimized, Huckstep nailing should be done. This generally requires 4 to 6 weeks. 3) The mean duration of bone union was 21.2 weeks. 4) Early joint mobilization can be done. The results of 17 cases were excellent by Denker's criteria. 5) Important complication were metal failure with refracture, screw failure and refracture after extraction of nail, these were caused by incorrect placement of nail, incorrect length of nail and more rapidly early weight bearing. 6) Nail of 11.5 mm in diameter is suitable in our study.

The clinical observation was performed on 27 patients of acetabular fracture, who had been admitted and treated at Department of Orthopedic Surgery, Choong-ahng Gil Hospital from January 1983 to December 1986. The results obtained were as follows. 1. The prevalent age ranged from 20 to 50 years, and the ratio between males and females was 2.4:1. 2. The most common cause of injury was traffic accident. 3. According to Letournel's classification, 8 cases were posterior wall fractures, 4 cases were pure transverse fractures, 3 cases were “T” shaped fractures, and 3 cases were fractures of both column. 4. The most common associated injury of the another part of the body was pelvic bone fracture and the most common associated soft tissue injury was cerebral contusion. 5. The satisfactory result of conservative treatment was 84.6% and surgical treatment was 78.6%. 6. The complications were degenerative arthritis(66.7%), bed sore(13.3%), ectopic ossification(6.7%), sciatic nerve palsy(6.7%), pin tract infection(6.7%) respectively. 7. The accurate anatomical reduction & rigid fixation was an important factor for intraarticular fracture.
