대퇴골 과상부 골절에 대한 연구 : 과간 골절을 중심으로 Focus on Intercondylar Fractures

이준규,임상덕 충남대학교 의과대학 지역사회의학연구소 1987 충남의대잡지 Vol.14 No.2

Supracondylar and intercondylar fractures of the femur remain difficult fracture to treat successfully, because of specific anatomical structure and location. There was a controversial in method of treatment, classification, and clinical result. Any mode of classification in intercondylar fracture, which reflects profound relationship of clinical aspects, has not been presented yet. So, a new classification system for fracture of the intetcondylar fracture of the distal femur are presented and clinical results are analyzed, according to type of fracture. The result are as follows: 1. The prevalent age was 3rd and 4th decade, and the sex ratio between males and females was 3.5:1. The mean age was 37.3 years old. 2. The satisfactory result of surgical treatment was 56.3% and conservative treatment was 33.3% respectively. 3. The intercondylar fracture of the distal femur were classified into 4 types, based on state of cortical comminution and involvement of joint surface. Type A (simple intercondylar fracture): there was no or slight comminution. Type B(lateral comminuted intercondylar fracture): there was comminution on lateral side of supracondylar or condylar cortex. Type C (medial comminuted intercondylar fracture) :

Massive pelvic disruption is an important and aften life threatening injury. The goals of orthopedic management of pelvic bone injuries are mobilization of parient as early as possible by achieving anatomical reduction and secure fixation of fragments. The authers reviewed 26 cases of unstable pelvic bone fracture treated at the orthopedic department of Chung Nam National University Hospital during the period from January 1985 to August 1990. The injury was classified according to the Pennal and Bucholz method and analyzed the causes of injury, methods of treatment. The results were obtained as follows. 1. The highest incidence was in the 3rd decade and sex ratio between male and female was 6:7. 2. The causes of injury were traffic accidents, fall down, motor bicycle accidents, industrial accidents in order of frequency. 3. According to classification of Pennal et al, type II fracture due to lateral compression injury was most common(68%). According to classification of Bucholz, type II fracture was most common(77%). 4. The fracture of tibia or fibular was most commonly associated bone injury and the most common associated soft tissue injury was genitounary tract injury. 5. 10 cases of Bucholz type II were treated with external fixation with internal fixation or internal fixation. 6 cases of Bucholz type III were treated external fixation or external fixation with internal fixation or internal fixation. 6. The result analysed by grading the outcome of pelvic fracture proposed SAID ABDUL MAJEED were excellant, good, fair, poor; 4, 6, 4, 0, in operative cases, 0, 3, 3, 4 in conservative cases. 7. The average weeks of immobilization were 6 in operative cases, 12 in conservative cases. 8. Even unstable pelvic bone fracture, we recommend early anatomical reduction and secure fixation with operative management.

The fracture of the ipsilateral femur and tibia is ususlly produced by violent external forces. It has many problems in the treatment, and may produce many complications. There are no many literatures about the method of treatment, and it may produce variable prognosis with different treatment. The most important objectives of the treatment is the restoration of the function. It can be obtained by early exercise therough the rigid fixation of the both fractures. The authors reviewed 18 cases of fracture of the ,ipsilateral femur and tibia treated at the department of orthopaedic surgery CNUH. and compared the results according to the method of treatment. The results were as follows: 1. Fifteen patients were male, and three patients were female. Of the eighteen patients, eleven patients were at their third and fourth decades. 2. The causes of the injury were traffic accident in fifteen cases, and industrial injuries in three cases. 3. The femoral fractures were open in five cases, and in twelve cases of the tibial fractures. 4. The femur fractures wer treated by internal fixation in sixteen cases, and by conservative treatmentin two cases. 5 The tibial fractures were treated by internal fixation in eight cases, by external fixtion in eight cases, and by conservative treatment in two case. 6. After follow up, the restoration of the function was maximum in the group of femoral internal fixation and tibial internal fixation, and the restoration of the function was minimum in the group of conservative treatment of the femur fractures. 7. The most important point of the treatment was early exercise through the rigid fixatioo of the both fractures.

Sacral fractures and lumbosacral dislocation are rare condition but almost constitute approximately 1% of all spinal fractures. They are frequently associated with pelvic fractures and often are overlooked. Lafollette, Levine, and McNiesh noted that 60% of sacral fractures are missed initially. So simple plain radiology are not sufficient for diagnose sacral fractures. Recently advanced diagnostic immaging technique, ie computerized tomogram, has more accate diagosis of sacral fractures. A high index of suspicioun is necessary to diagnose sacral fractures in patients with multiple trauma. The most common causes of this fractures are motor vehicle accidents and falls. Neural and nerve roots damage frequently noted in sacral fractures and lumbosacral dislocation because sacrum is continuation of the spine and contain of the neural tissue. The classification of sacral fractures are not well established until now, some authurs classified sacral fractures with corelation of neural damage, but it is not clear betwen fractures pattern and prognosis. The aimes of paper to evaluation of neural damage incidence, fracrures patterns, prognosis of the sacral fractures, So we studied 12 cases of sacral fractures retrospectively admmited to Dept' of orthpaedic surgery of Chungnam university hospital from 1987 to 1992 and mean follow up is 27 months. The results of this study are following. 1) Sacral fractures combined pelvic fracure always. 2) Simple plain X-ray missed sacral fractures frequently, so computerized tomogram is necessary at unstable pelvic fracture. 3) The sacral fractures are involved the neural canal and foramen commonly, but neural deficits are uncommon. 4) The overall prognosis of sacral fractures are followed by combined pelvic farctures. 5) The isolated sacral fractures are rare and the prognosis is good.

이준규,김경태,오기영 충남대학교 의과대학 지역사회의학연구소 1995 충남의대잡지 Vol.22 No.1

We conducted a clinical effectiveness and safety of Loxoprofen sodium, a nonsteroidal antiinflammatory drug(NSAID) for the treatment of chronic low back pain. Loxoprofen sodiun 180 mg/day(60 mg three time daily) was administered to 30 patients with chronic low back pain associated with a range of arthritic disorders, for a period up to 4 weeks, and clinical efficacy was evaluated by objective and subjective methods. 4 weeks therapy, loxoprofen showed subjective improvements of 100%, 64.7% and 63.6% in patients with mild to moderate, moderate to severe, and severe lumbar pain etc, respectively. Objective and subjective improvements were significant after only 1 week therapy in patients with mild to moderate pain and after 4 weeks, over all intensities of pain were improved. The incidence of adverse effects over this study population was extremely low, affecting only 3.3% of patients, and were mild in nature and edematous change. Loxoprofen is thus a well-tolerated NSAID in the treatment of chronic lumbar pain.

승온시 Si₂H가스 주입을 이용한 저온 Si 에피택시에 관한 연구

In this study, we studied on the low temperature Si epitaxy growth for Si epitaxial growth temperature below 650。C. Usually, the Si epitaxy films by chemical vapor deposition are crystallized to polycrystalline films due to a formation of SiO₂layer at the epitaxial Si/Si substrates interfaces. Formation of SiO₂layer on Si surface can be effectively prevented by flowing the Si₂H?? gas during the heating-up procedure for Si deposition. In this way, Si epitaxial layer onto (100) Si substrates was grown epitaxial layer during the post-deposition heat treatments. The suppression of surface BIO₂can be explained in terms of adsorption of SiH?? adspecies, instead of oxygen from residual gases in the reactors, to Si surfaces after desorption of hydrogen from H-passivated Si surfaces. Employing Si₂H?? flowing and epitaxial growth, high-quality epitaxial Si layer was the low temperature below 650。C without conventional high temperature cleaning procedures. And the crystallinity of epitaxial layer measured as deposition conditions using ultraviolet reflectance. AS this results, we could be aquaired process temperature region for high-quality low temperature Si epitaxial growth.

In general, hangman's fracture, odontoid Type III fractures, and most miscellaneous axis fractures are effectively managed with nonoperative methods (typically, the halo vest with its rigid external immobilization). Halo apparatus is a reliable instrument for the management of cervical spine injury, including that of odontoid fractures and other C1-2 injuries. Surgical fusion is the usual alternative to the halo device. Posterior wiring with or without fusion using autogenous iliac bone graft is probably the most common surgical treatment of cervical spine fracture and dislocation. The purpose of this study was to compare with stability of each others and to estimate the atlanto-dental interval and space for available in patients who were received conservative treatment and operative treatment due to upper cervical spine fracture and/or dislocation. 25 patients who were recieved conservative and operative management due to fracture and/or dislocation of the upper cervical spine (Cl and C2) during 1990. Jan. to 1997. May. were defined as a patient group. 12 patients were received conservative treatment. 13 patients were received operative treatment. In patient group who were received conservative treatment, the average of ADI and SAC was within normal range. In patient group who were received operative treatment, the average of ADI and SAC was within normal range. The patient group with the ADI and SAC of normal range were stable with good bone union at the last follow-up examination. Also the patient group was received fusion as their initial treatment for injuries incurred 1 month to 8 month prior to hospitalization were stable with good bone union.

요통의 생체 역학적 연구 : 추간판 장애의 추간판 조영술을 동반한 컴퓨터 단층 촬영의 의의 The significance of the discography with computed tomogram for the internal disc derangement

The utility of the discorgram in diagnosing of the painful discs remains controversial. We performed discography with computed tomogram and evaluated the relationship between volume, pressure resistance, pain response and discs morphology. The results of discogram of 72 discs were reviewed retrospectively. All patients had chronic back pain unresponsive to conservative measures. Discogram were performed by one examiner using the same method subjectively documenting pain response(PR), pressure(P) immediately after penetration of the nucleus and then prior to removal(Low, High), volum(V) of Iohexol in ml and immediately followed by biplanar X-ray and computed tomogram(CT) scan. A positive pain response was defined as Grade Ⅲ or Ⅳ. Discogram morphology was classified into 5 Types, Type Ⅰ being a normal appearing disc and Type Ⅴ showing greater than 60% degeneration. Reviewers of X-ray studies were blined to the clinical data and those reviewing the clinical date were unaware of the morphology. In general a trend of increasing pressure is evident as disruption worsens. When a subgroup of discs with a low-to-high pressure response in disc morphology Type Ⅳ and Ⅴ was examined separately 30 of 34 levels, 88%, were pain response positive. The subgroup high-to-high had a distinctive immediate pain response positive in 6 to 9, 67%, positive responders. The results of this study may increase the predicability of a positive pain response and elucidate the possibility of different pain mechanism in disc pathology.
