BACKGROUNDS: The high mortality and morbidity rates associated with traumatic rupture of the hollow viscera have been attributed to the clinical difficulty in establishing an early diagnosis. The accuracy of CT in the detection of injuries of the solid visceral organ is well established, but the value of CT in diagnosing small bowel perforation artier blunt abdominal trauma is controversal. This study was conducted to ascertain CT findings of small bowel perforation result from blunt abdominal trauma. METHODS: A retrospective analysis of preoperative abdominal CT findings in 40 patients was performed. Small bowel perforation was confirmed by surgery. Precontrast and postcontrast enhanced CT images were obtained in all patients. RESULTS: Diagnostic findings of small bowel perforation including intraperitoneal or retroperitoneal free air, discontinuity of the bowel wall and extravasation of oral or IV contrast materials were observed in 34 cases(85%). The most common fading of small bowel perforation was intraperitoneal or retroperitoneal free fluid collection(90%), followed by segmental bowel wall thickening(83%), intraperitoneal or retroperitoneal free air(80%) and focal mesenteric fat infiltration(70%). CONCLUSIONS : The CT scan is sensitive and effective modality for evaluation of small bowel perforation after blunt abdominal truauma, because of high detectability of diagnostic antral suggestive CT findings.

The advantage of the radiofrequency lesion method are presented, with excellent control of the lesion volume, excellent control of the lesion process using temperature monitoring to quantify the lesion size, prevent boiling, and to produce differential destruction of neural tissue. The presence of afferent fibers in the ventral root which are spared by dorsal rhizotomy suggested an explanation for the failure of this procedure. Nerve fibers with their cells in the ganglion from ventral root will be destructed with streotactic radiofrequency ganglionotomy. Since the dorsal root ganglion cells are more sensitive to than are other structures within the bundle, one is using a differential heat lesion to specifically affect pain pathways while leaving motor pathways. proprioception, and afferent input relatively intact. In the higher thoracic regions, the pleura can be injured when using an traditional approach. Hence in the upper thoracic region(T2-T9), this type of approach requires that a small burr-hole be made at the superior aspect of the corresponding thoracic zygapophyseal joint. Stereotactic thoracic dorsal root ganglionotomy have carried out under local anesthesia on an inpatient basis in 6 patients. A series of 5 patients with metastatic cancer pain and a patient with compression fracture have treated with stereotactic radiofrequency lesioning of the thoracic dorsal root ganglion. Four out of these 6 patients have been relieved of pain without serious complications. I think this should be a good armamentarium to the pain therapists in the management of intractable pain.

Osteoid osteoma is a distinctive benign lesion characterized by a less then 2 cm, pea-like mass of abnormal bone (nidus). The common sites of osteoid osteoma are femur, tibia, humerus, spine and talus. Mastoid tip, clavicle, acetabulum, coccyx, rib, hamate, scapula and scaphoid are rare sites of osteoid osteoma. Osteoid osteoma of the patella is also very rare and on review of literatures we could find only one reported case which was treated by surgical excision. We also experienced one case of osteoid osteoma located at the patella, so we report this case with review of literatures.

The Ilizarov technique for gradual distraction osteogenesis was developed in the 1950s. A correctly performed osteotomy is essential to the success of distraction osteogenesis and prepares for limb lengthening. Between Sept. of 1991 and 1994, thirty-four patients were treated by Ilizarov technique at St. Benedict Hosp. and Gang-Dong Hosp.. And then assigned to two separate groups : a corticotomy group (group A) and osteotomy group (group B; osteotomy with Gigli saw or osteotomy with multiple drill holes and osteotome). The regenerate segments were evaluated weekly for the first six weeks after operation. After the initial six-week evaluation period, observations of these segments were continued through a series of monthly radiographs. Distraction began on postoperative day seven in group A and on day eleven in group B; and continued at a rate of 1 mm/day and a frequency of 4 times/day. Group A displayed new bone formation earlier than group B: group A's mean was 16.5 ± 4.9 days, while B's mean was 25.3 ± 4.6 days. The first bridging callus occurred earlier in group A than it did in group B: A's mean was time of 36.7 ± 9.9 days, while B's mean was 44.0 ± 7.9 days. There was no significant difference between groups A & B in terms of first cortical formation : A's mean was 86.9 ± 24.0 days, and B's mean was 100.6 ± 25.2 days. There was no significant difference between groups A & B in terms of the bone healing index : A's mean was 41.6 ± 13.5 days and B's mean was 41.15 ± 8.10 days.

We experienced a case of unilateral vocal cord paralysis following tracheal extubation. The patient was a 60-year-old man undergoing subtotal gastrectomy. He had no laryngeal symptoms prior to operation and the trachea was intubated with a cuffed endotracheal tube. The surgical procedure lasted 6 hours and was uneventful. Three days later after operation, he began to complain of hoarseness and mild aspiration symptom. On endoscopic examination, left vocal cord paralysis was found. Fifteen weeks later the voice and left vocal cord function return to normal without specific management. In this case, we suggested that possible causes of unilateral vocal cord paralysis are compression of recurrent laryngeal nerve by overexpanded endotracheal cuff, laryngeal trauma during difficult intubation, stretching of the nerve as a result of traction on distant organ, decreased elasticity of trachea and surrounding tissues in the older age group and long operating time.
