Tibial Plateau fracture is relatively common injury which often produce major disability, and their treatment has been in controversy. Recent studies suggest that early knee motion and perhaps better surgical techniques have improved clinical end results. Protection from weight bearing and length of immobilization have varied among authors and variable treatment methods. Thirty-eight tibial plateau fractures treated at Kangnam Sacred Heart Hospital from March in 1984 to December in 1988 were analized and the followings were obtained. l. Of 38 patients, 29 patients were male and 9 female. 2. The most common associated injury was an ipsilateral fibular fracture. 3. Average duration of immobilization was 4 to 6 weeks in conservative treatment and 2 to 4 weeks in operative treatment. 4. We started partial weight bearing in 24 patients within 6 weeks and full weight bearing in 28 patients between 8 and 12 weeks, and good end results were obtained.

Nine patients with ipsilateral tibial shaft fractures and knee ligament injuries were retrospectively reviewed to determine the methods of the diagnosis and the results of the treatment. The incidence of this combined injuries was 5% in one hundred and eighty two tibial shaft fractures. The injuries of posterior cruciate ligament were combined most freqently. Five of nine patients were open fractures. Bone union was obtained in all cases and the mean duration of bone union was 22.5 weeks. Athroscopy and stress X-ray for the cruciate ligament were helpful to diagnose this combined injures. The ligament injuries were surgically managed in eight and conservatively in one. Better results were obtained when this combined injuries were operated early, but four of nine patients were disabled. The results suggest that the examination of the knee is necessary to document ligamentous injuries that occur with tibial shaft fractures.

Thirty-two consecutive patients with spondylolisthesis associated with displacement in varying degrees were operated by the Steffee procedure. Slippings more than Meyerding Grade III were reduced by modified Schollner technique:destabilization of the slipped segement, local distraction with spinal elevator and completion of reduction with a cork screw force pulling backward. Autogenous bone and Pyrost were added to get solid fusion. The authors reviewed thrity-two cases of symptomatic lumbar spondylolisthesis which were operated since March in 1987 at Kangnam Sacred Heart Hospital, Hallym University and the followings were obtained. 1. There were 17 males and 15 females, and the age of the patients was 44.2 years in average ranging from 19 to 66 years. 2. The types of spondylolisthesis were isthmic defect at 19 levels in 18 cases and degenerative in 14 cases. The level of the lesion was L5-Sl in 17 cases, L4-5 in 15 cases and L2-3 in 1 cases. 3. The clinical symptoms were low back pain, radiating pain, intermittent claudication, and motorsensory deficit in order of incidence. 4. Preoperatively, the degree of slinpping was Meyerding Grade I in 18, Grade III in 12 and Grade Ill in 3 cases. The slipping was reduced to nearly anatomic position in 13 cases and Grade I in 20 cases. The average slipping measured by Taillard method was changed from 23.4% preoperatively to 5% postoperatively. 5. Clinically, the results were judged as excellent in 13(13%) cases, good in 16(50%) cases and fair in 3(9%) cases according to Kim's criteria. 6. Postoperative complications were leg pain in 3 cases and "stress transfer" in 1 cases.

There are several rnethods to correct the tibial bony defect including resection, cement filling, autograft or allograft and metal augmentation. The purpose of this study is to find the adequate treatment method of tibia bony defect through analysis of the result with above methods. From Sep. 1993 to Dec. 1997, the authors analyzed 93 cases of tibial medial bony defect corrected by overresection of lateral condyle, allograft and metal wedge or block among 358 cases of primary total knee arthroplasty(TKA) operated at Asan Medical Center. All cases were devided into four groups according to the treatment method; group A(31 cases) with overresection of lateral condyle, group B(37 cases) with metal wedge, group C(21 cases) with metal block and group D(4 cases) with allograft. The mean follow up period was 23.6 months(12 56 months). The results were as follows, 1. There were no definite statistical difference between group A, B, C and D in HSS knee score, ROM, correction of deformity. But in group D, there is one case of loss of the correction. 2. Loosening of the implant was not noted, but 17 cases of mild bony resorption was found just beneath the implant. It was particularly prominent in group B(9 cases) than group A(5 cases) and C(3 cases). 3. Among 4 cases of allograft, one has developed collapse of allograft. 4. 3 cases of deep infection developed only in group C, which were followed by revision TKA. Although further follow up study should be carried out, we concluded that resection of lateral tibial condyle, allograft, metal augmentation is a good substitute to the correction of the tibial bony defect in primary TKA.

BACKGROUND: Trauma is the third leading cause of death, irrespective of age, and the leading cause of death in persons under 40 years of age. Computed tomography (CT) is an effective technique in the initial emergent evaluation of the abdomen and head following blunt trauma. Most chest indies are not seen on conventional chest radiography, or may be underestimated. But routine use of CT in the initial emergent evaluation of chest trauma is controversial. CT, however, has been shown to be useful in the diagnosis of unsuspected chest injuries and in directing therapeutic interventions. This review discusses the efficacy of emergent CT in patients with blunt trauma on the chest. METHODS: To evaluate the efficacy of CT of the thorax, a retrospective study comparing early thoracic CT scanning with initial chest roentgenogram(CXR) was carried out on 121 patients with blunt trauma on the chest. The interval between CXR and CT was less than 1 hour. RESULTS: Among 121 patients, 42 patients had normal initial chest roentgenogram in whom 19 patients showed normal CT findings. Sensitivities of diagnosing pneumothorax and pleural effusion by CXR were low (49.3%and 45.1%respectively), whereas 65.7% (44/67) of patients had thoracostomy only by CXR. CONCLUSIONS : Although sometimes abused in patients with chest trauma, CT of the thorax is an effective method of detecting thoracic injuries and provides accurate information regarding their pattern and extent in the initial emergent diagnosis.

Folliculosebaceous cystic hamartoma (FCH) is a recently recognized adnexal tumor and is composed of follicular, sebaceous and mesenchymal elements such as small vessels, adipocytes and neural component in the fibrous stroma. It usually presents as an exophytic papule or nodule on the central part of the face. We describe a 39-year-old woman with FCH on the right upper back, which is an unusual site. A biopsy specimen demonstrated a follicular structure in infundibuiar nature, sebaceous lobules attached to it, and compactly laminated fibrous stroma with an increased number of vessels in it. Immunohistochemically, many of the vessels in the stroma showed positive reaction for CD34, and Factor VIII.

The fractures of the cervical spine are relatively uncommon, but they may cause serious neurologic deficits temporarily or permanently. So, it is very important to treat the patients early by way of exact evaluation for the sites and the mechanisms of the injuries. The authors reviewed retrospectively 188 cervical spinal fractures in 100 patients from Sep. 1984 to Aug. 1990. Commonly involed levels were C5 and C6 in lower cervical level and C2 in upper cervical level and the sites in each spine were body; lamina and odontoid process. The hyperflexion injury was the most common type of the cervical spinal fractures occupying 53% of all cervical fractures and cause more multipe fractures(2.26 fractures/patient) than in hyperextension (1. 68 fractures/patient). In hyperflexion injuries, body, transverse and spinous process were commonly involved but lamina fracture was relatively common in hyperextension injury. The dislocations associated with fractures were developed most commonly in hyperflexion injury and 70% of these were anterior dislocation and the most commonly involved levels were C5-6 and C6-7. In conclusion, hyperflexion injury needs more close examination for the entire spinal levels than injuries of other mechanisms because it results in more severe fractures with or without dislocation and relatively frequent multiple fractures in different levels.
