Diver's bone lesion was described for the first time by Grutzmacher in 1941. Ten cases of osteonecrosis of the femoral head in divers were analysed on the basis of clinical and pathologic feature. The pathologic feature of the osteonecrosis in divers was not reported in Korea previously. The cases were observed from March, 1985 to June, 1988. The authors treated the cases with total hip replacement and obtained good results. The results were as follows:1. The average ate age at the time of operation was 41.5 years. 2. The average follow-up was 20.4 months. 3. The specimens were confirmed as osteonecrosis mieroscopically. 4. By Meyer's modification of Marcus and Enneking classification the average stage was 3.7. 5. Divers bone lesion was increased with the length of diving experiences:diving depth, diving time, age and with bends. 6. The pathologic feature of osteonecrosis in divers differ from that of idiopathic avascular or aseptic osteonecrosis and could be differentiated easily. 7. After total hip replacement, according to Harris hip rading score system, all results were good.

STUDY DESIGN: This is a retrospective study analyzing 73 patients treated by decompression, pedicular screw instrumentation and posterior lumbar interbody fusion (PLIF) for lumbosacral spondylolithesis and symptomatic spinal stenosis. we used laminected laminar and spinous process instead of iliac bone. OBJECTIVES: This is to evaluate fusion rate and clinical results of PLIF with laminected laminar and spinous process. MATERIALS AND METHODS: PLIF in 73 patients with lumbosacral disorders who carried out at Pohang St. Mary's Hospital from March 1994 to January 1996. Fusion rate was evaluated by simple X-ray and dynamic view. Clinical effect was evaluated by Kirkaldy-Willis criteria. RESULTS: The solid fusion was achieved at 67 cases(91.8%) and the average period of fusion was 6.4 months. Complications were 2 cases of superficial skin infection and 3 cases of root irritation. The functional results by Kirkaldy-Willis were as follows ; excellent 40 cases, good 23 cases, fair 9 cases and poor 1 case. CONCLUSIONS: This PLIF procedure combined with transpedicular instrumentation showed sufficient fusion rate and excellent clinical results and improvement in vertebral alignment.

Osteoporosis is the most common generalized skeletal disease, which lays a significant socioeconomic burden to Korea. The early diagnosis and treatment of osteoporosis are of the great interest to minimize the economic co nsequence. We have studied vertebral BMD and bone scan of 30 patients with osteoporotic compression fractures. The purpose of this study was to investigate the effect of osteoporotic compression fracture on bone mineral density(BMD). We have measured the vertebral heights, vertebral bone mineral density, and bone scan counts of vertebral bodies on osteoporotic patients. Vertebral BMD was measured from T12 to L4 using dual photon absorptiometry. Anterior(Ha), middle(Hm), and posterior(Hp) height of vertebrae were measured from T12 to L4, and the spinal deformity indices(Ha/Hp, Hm/Hp, and Hp/Hi ratios) were calculated. The bone scan counts were measured from T12 to L4, and bone scan ratios were calculated. The BMD of fractured vertebrae was significantly higher than that of non-fractured vertebrae The spinal deformity indices were not correlated to the BMD of fractured vertebrae. The bone scan ratio was correlated to the BMD of fractured vertebrae. This study suggests that the increased BMD observed in fractured vertebrae is related to metabolic effect of compression fractures rather than mechanical effect.

Dyke-Davidoff-Masson syndrome is a rare disorder which developed hemiatrophy of brain, enlargement of ventricles and prominent pneumatization of petrous pyramid of the temporal bone. It manifests hemiparesis, varying type seizure, and mental retardation. We experienced two cases of Dyke-avidoff-Masson Syndrome, in a 6/12 year-old boy and a 1, 10/12 year-old girl who were admitted to our department of pediatrics, because of convulsion and hemiparesis The brain CT scan showed marked dilatation of lateral ventricle, prominent sylvian fissure and cortical sulci. So we report two cases of Dyke-Davidoff-Masson syndrome with review of literature.

PURPOSE: To evaluate the clinical efficacy of amniotic membrane transplantation and limbal-conjunctival autograft for patients with recurrent pterygium or pseudopterygium, the results of 15 eyes of 14 patients were analyzed. METHODS: Total 10 cases of recurrent pterygium and 5 cases of pseudopterygium were surgically managed during June 1998 to July 2000. After excision of pterygium, amniotic membrane was attached on the bare sclera and limbal-conjunctival autograft was transplanted over the amniotic membrane. Mean follow-up period was 47.2 week and all patients were examined for recurrence, which was graded from G0(no vessel) to G3(fibrotic tissue invading the limbus). RESULTS: 12 out of 15 cases(rate 80%) showed no recurrence(grade 0). 1 case of grade 2 recurrence and 2 cases of grade 3(total 3 cases) were observed(rate 20%). Reoperation was performed on 2 cases of grade 3 recurrence. There was no further recurrence necessitating additional reoperation. 1 case of limbal graft was detached and removed. The operation time of this more prolonged than the other procedures, but there were no significant complications. CONCLUSION: Amniotic membrane and limbal-conjunctival autograft for patients with recurrent pterygium or pseudopterygium reconstructed complete ocular surface with less recurrence. Therefore, we recommend this surgical approach as a safe and effective method for the treatment of complicated cases of pterygium.

Narcotic analgesics may be added to spinal anesthetics solution to improve the quality of sensorimotor blockade and to produce postoperative pain relief. The opioid-related side effects of respiratory depression, pruritus, nausea, and urinary retension also occur with intrathecal administration and the effects are dose-related. It is difficult to select morphine with spinal anesthetic solution due to fatal side-effect, respiratory depression. Intrathecal morphine dose used for our study was less than 1mg, thereby the risk of respiratory depression was decreased. There was no report that the addition of morphine affected the motor block produced by the local anesthetics in spinal anesthesia. But in our study, we found that 0.9 mg of intrathecal morphine produced prolongation of optimal condition for operation(more than 3 hours duration), and sufficient postoperative pain relief(for about 20 hours) without respiratory depression in 28 out of 30 spinal anesthesia cases. On the other hand, 0.5 mg or 0.7 mg of intrathecal morphine produced sufficient postoperative pain relief without respiratory depression(for about 20 hours), but insufficient prolongation of optimal condition for operation in each 30 cases of spinal anesthesia.

The most common cause of orbital in/fection is a sinusitis, and if this orbital complication is not provided with appropriate and intensive treatments, serious status such as visual loss or life-threatening may occur. Osteomyelitis rarely results from sinusitis, and in cases where it happens, the frontal sinus is the most frequently involved site. However, zygomatic osteomyelitis has not been reported so far. We present a case of maxillary sinusitis which was initiated by oroantral fistula, and developed to preseptal and postseptal abscess, penetrating into the orbital septum. The case was complicated by zygomatic osteomyelitis. This case was successfully treated by draining pus by endonasal endoscopic sinus surgery, infraorbital incision, and was followed by antibiotic therapy for about 8 weeks.
