STUDY DESIGNS: Retrospective analysis of the surgical treatment in patients of thoracolumbar spine fractures. OBJECTIVES: To measure by modified Cobb method the correction angle of thoracolumbar vertebral fractures and to comparison the difference between short segment pedicular fixation with fractured vertebra(group A) and without fractured vertebra (group B). SUMMARY OF LITERATURE REVIEW: The major treatment of thoracolumbar spine fractures is surgical correction of kyphotic angle by posterior decompression and posterolat. fusion at one level or more. MATERIALS AND METHODS: The materials are the patients who visited due to trauma beween 1991.1 and 2000.12. and treated by post. decompression and short segment posterolat. fusion with iliac bone graft. The number were A group, 28 persons and B group, 15 persons. The method of radiologic measurement is done by the modified Cobb method. The follow up time is till 2001.7. and the duration are minimal 6 months and maximal 77 months. The age was between 17 old and 60 old. The neurologic abnormalities in patients are 12 persons. The fractures were classified by the Denis classification. There are compressive fracture are 3 persons and bursting fracture type A are 18 persons, type B are 22 persons. The materials were confirmed by radiologic union and excluded if more than one vertebra fusion is needed. RESULTS: The most fractures were due to falldown injury. The most fracture site was T-L level (T12-L3). The one case was complicated by deep infection and treated and the other case was reduction loss due to metallic failure. The results of the loss of correction were A group, 5.3 degree and B group, 6.2 degree. (P>0.05). The relative correction loss were A group, 42%, and B group, 54%. (P<0.05). CONCLUSION: The mean correction angle and loss of correction are more good results in the group of short segment pedicular fixation with fracture vertebra. But to get more good results, our study do more long term follow-up and rule out other statistical errors and consecutive radiologic follow-up.

PURPOSE: Neurofibromas may present as multiple or solitary lesions. Although there is no predilection site for solitary lesions, they are rare on the hand. In addition, solitary intramuscular neurofibromas are a very rare pathological type. Here, we report a rare solitary intramuscular neurofibroma in the hand. This paper examines the clinical characteristics of intramuscular neurofibroma arising from the lumbricalis in order to enable a correct diagnosis and treatment. METHODS: A 32-year-old male presented with a painless mass on the palm. The physical examination revealed a 3 x 2cm protruding mass that was non-tender to palpation. The vascular and sensory examinations were unremarkable, while the motor examination showed mild difficulty with flexion and extension. Magnetic resonance imaging demonstrated an enhancing solid mass between the thenar eminence and second metacarpophalangeal joint. The diagnosis of an intramuscular neurofibroma was confirmed following surgical excision and histological evaluation. RESULTS: The pathological examination was consistent with a neurofibroma, with delicate fascicles and loose fusiform cells in a fibrous stroma, with oval or spindle-shaped nuclei and scant cytoplasm. The background matrix was pale staining and had focal myxoid stroma. There was no significant nuclear pleomorphism and no mitoses. Immunohistochemistry with S-100 was slightly positive. At the 6-month follow-up, motor and sensory function were intact and the range of motion was full. CONCLUSION: A neurofibroma is a rare tumor of the hand, especially the intramuscular type. Hand surgeons should consider the diagnosis of this tumor based on the examination and imaging.

PURPOSE: Hands are the chief organs for physically manipulating the environment, using anywhere from the roughest motor skills to the finest, and since the fingertips contain some of the densest areas of nerve endings on the human body, they are continuously used organ with complex functions, and therefore, often gets injured. To prevent any functional loss, a detailed anatomical knowledge is required to have a perfect surgical treatment. Also it is necessary to have a thorough understanding of arrangements of the human extensor tendons and intertendinous connections when tenoplasty or tendon transfer is required. We performed a study of the arrangements of the human extensor tendons and the configuration of the intertendinous connections over the dorsum of the wrist and hand. METHODS: A total of 58 hands from Korean cadavers were dissected. The arrangements of extensor indicis proprius, extensor digitorum communis, and extensor digiti minimi tendons and intertendinous connections were studied. RESULTS: The most common distribution patterns of the extensor tendons of the fingers were as follows: a single extensor indicis proprius(EIP) tendon which inserted ulnar to the extensor digitorum-index(EDC-index); a single EDC-index; a single EDC-middle; a double EDC-ring; an absent EDC-little; a double extensor digiti minimi(EDM), a single EDC-index(98.3%), a single EDC-middle(62%), a double EDC-ring(50%), and an absent(65.5%) or a single (32.8%) EDC-little. A double(70.6%) EDM tendons were seen. Intertendinous connections were classified into 3 types: type 1 with thin filamentous type, type 2 with a thick filamentous type, and type 3 with a tendinous type subdivided to r shaped 3r type and y shaped 3y type. The most common patterns were type 1 in the 2nd intermetacarpal space, type 2 in the 3rd intermetacarpal space, and type 3r in the 4th intermetacarpal space. And in the present study, we observed one case of the extensor digitorum brevis manus(EDBM) on the boht side. CONCLUSION: A knowledge of both the usual and possible variations of the extensor tendon and the intertendinous connection is useful in the identification and repair of these structures.

The mainstay of diagnosing scrub typhus is through serologic testing. However, because of the delay of several days from the onset of the illness to the increase in the antibody titer, diagnosis can be difficult in the early stage of the illness. The aim of this study was to determine the clinical usefulness of adenosine deaminase activity (ADA) in diagnosing scrub typhus. A total of 104 patients were enrolled during the study period. Of these patients, 59 patients were diagnosed with scrub typhus and the mean serum ADA level was 46.7+/-11.6 U/L. High serum ADA levels strongly supported the diagnosis of scrub typhus, especially in patient without eschar. The remaining 44 patients did not have scrub typhus and 95% (42/44) of them had normal serum ADA levels. Therefore, evaluating serum ADA level could help diagnose patients with acute febrile disease such as scrub typhus, especially in its early stage of disease progression.

PURPOSE: To investigate postoperative incidence of complications and functional results between two groups, primary bipolar hemiarthroplasty and internal fixation with compression hip screw on unstable intertrochanteric fractures of the femur with severe osteoporosis in elderly patients. MATERIALS AND METHODS: 78 cases treated under unstable intertrochanteric fractures of the femur with severe osteoporotic elderly patients from March 1997 to August 2001 who have been followed up for more than a year were evaluated retrospectively between the group of bipolar hemiarthroplasty, 38 cases out of 60 cases and group of compression hip screw, 40 cases out of 59 cases. The incidence of complications and functional ability according to Merle d'Aubigne scale and the mortality rate were compared using student t-test. RESULTS: The means of Merle d'Aubigne scale for the hemiarthroplasty group and the compression hip screw group were at the last follow up, 15.0 and 13.6 respectively. The differences were statistically significant (p=0.04). Bipolar group revealed significant differences in general (18%) and mechanical complications (5%) between two groups (p<0.05). The mortality rates were 28% and 22% respectively and there were no significant differences statistically (p>0.05). CONCLUSION: We consider that primary bipolar hemiarthroplasty would be better method in the treatment of the unstable femoral intertrochanteric fracture with severe osteoporosis but we need much longer follow up.

The present research was conducted through the research fund of Dankook University in 2006. Rectal recurrence of gastric cancer is uncommon. A few cases have been reported, with the majority of them associated with peritoneal recurrence. A 71-year-old man visited our hospital complaining of bowel habit changes and fecal incontinence. He had undergone radical subtotal gastrectomy and postoperative adjuvant chemotherapy for advanced gastric cancer 9 years earlier. Colonoscopy showed a rigidly constricted and erythematous rectum. Abdominopelvic CT showed diffuse rectal wall thickening with enhancement. PET-CT showed a hot uptake in the corresponding area on abdominopelvic CT scan, with no evidence of distant metastasis. We performed transanal full thickness biopsy and confirmed a diagnosis of adenocarcinoma pathologically similar to the former gastric cancer. The patient was diagnosed with solitary rectal recurrence simulating linitis plastica, without gastric remnant recurrence. We report this case with a review of the literature.

Interests in the microanatomy of the proximal segment of the internal carotid artery(ICA) have been increased due to the anatomical complexity of this region and the potential sites of the aneurysmal formation. In this study, microanatomical dissections were performed in 70 specimens obtained from 35 formalin-fixed human cadaveric heads to examine the superior hypophyseal arteries(SHAs), ophthalmic artery, and the carotid cave. In our study, 54(77%) carotid caves were presented in 70 specimens. Twenty-five(71%, 50 caves) cadavers harbored the carotid caves on both sides, 4(11%, 4 caves) cadavers only on the one side and the remaining 6(17%) didn't have the caval structure. Total of 162 SHAs which have showen to arise from the medial or posterior aspect of the ophthalmic(C6) segment of the ICA in all cases were identified: 108(67%) arose from the proximal half of the C6 segment and 54(33%) from the distal half. Interestingly, in 54 specimens which had the carotid caves, one to four SHAs arose from the part of the C6 segment within the cave in the 43(80%) specimens. Total number of the SHAs originated within the carotid cave were 51. Sixty-four(91%) of ophthalmic arteries have shown to arise just distal to the distal dural ring on C6 segment, whereas 4(6%) from the clinoid(C5) segment and in 2(3%) cases, the ophthalmic artery arose just at the insertion of the distal dural ring level. The authors describe the microanatomical relationships between the SHA and the carotid cave, and the origin of the SHA and the ophthalmic artery. We hope to get better knowledge of the vascular relationship and the possible mechanism of the SHA aneurysm.

STUDY DESIGN: A case report and review of the literature. OBJECTIVES: To discuss an epidural hemangioma and review the literature. MATERIAL AND METHOD: A 56-year-old woman had back pain and pain radiating to the left lower extremity that had gradually worse over 2 weeks. No definite history of trauma was disclosed. The straight leg raising test was positive at 60degree on the left side. Sensation to pinprick was diminished in the L5, S1 dermatome on her left leg. Examination of the left leg revealed weakness of the extensor hallucis longus(3/5 strength). Plain films of the lumbar spine showed degenerative scoliosis and degenerative L4-5 spondylolisthesis with no bone involvement. In retrospective study, T1-,T2-weighted image showed a hyperintense signal mass, unlike an usual MR imaging of epidural hemangioma. A preoperative diagnosis of spondylolisthesis with spinal stenosis was made. RESULTS: The mass compressing L5 root was excised through posterior approach and the fusion was performed from L4 to S1 with bone graft, instumentation. A purple encapsulated tumor, size 1.5x1x.8cm, was found. Histopathologic examination revealed a thin walled sinusoidal vascular space of varying sizes, lined with a single layer of endothelial cells, consistent with typical hemangioma. The patient had a complete neurologic recovery and is doing well 5 months after surgery. CONCLUSIONS: Although the diagnosis of epidural hemangioma was difficult, because of the rarity of that, we should pay attention to awareness of the possibility of such lesion, differential diagnosis in clinical manifestration, neuroradiologic study.
