Since the introduction of surgical microscope in microvesael surgery by Jacobson and Suarez in 1960, many surgeons have succeeded replantation, transplantation of composite segment of tissues so called free fiap-free bone graft and toe to hand transfer. McCraw & Furlow reported successfully transfered dorsal foot flap using dorsalis pedis artery in 1975 and Cobett transfered great toe to band for reconstruction of the amputated thunb. The authors experienced six cases of microsurgery using dorsalis pedis artery durig the recent two years in the department of Orthopaedic surgery of Soon Chun Hyang College and results in this paper. 1. Four cases out of six were dorsalis pedis free flap, one case was second toe to thumb and tbe other one was reconstruction of an amputated thumb in one stage using iliac bone graft and dorsalis pedis flap. 2. One case out of four cases of dorsalis pedis free flap was performed for reconstruction of contracted first web and the other cases were performed for foot. 3. Five cases out of six were successfully transfeed, one case which was toe to thumb was failed. The cause. of fail was probably due to post-operative hematoma. 4. Composite tissue using dorsalis pedis artery is one of the good donor site for composite tissue transfer for not only skin defect and scar contracture of the hand and foot but also reconstruction of the amputated fingers because it has several advantages; an acceptable thickness, a constant arterial supply, venous drainage through the saphenous system, and constant innervation through the terminal branches of the superficial and deep peroneal nerve.

Subtrochanteric fracture of the femur is more difficult to treat than other bone fracture. Subtrochanteric fracture occurs in bone that is predominently cortical and biomechanical analyeis of stress in the femur ahowed that there is a high concentration of stress in the subtrochanteric region. These two factors, involvement of cortical bone tissue and concentration of stress, frequently have been mentioned as reasons for the high incidence of complications in the treatment of these fractures. The authors treated 23 cases of subtrochanteric fracture of the femur in 1974 through 1981, at the Department of Orthopaedic Surgery, School of Medicine, Soon Chun Hyang College. The results were as follows: 1. Of 23 cases of subtrochanteric fracture, 15 cases occurred in man, 8 cases in woman. 2. The most common cause of fracture was due to traffic accident. 3. Of 23 cases of subtrochanteric fracture, 9 cases were type lI, and 7 cases were type I & II by Fielding's classification. 4. 19 cases out of 23 were treated by means of the open reduction and internal fixation. As the internal fixation material, we used Kuntscher nail, Smith-Peterson and Thornton plate, Compression hip screw and plate until December 1978, and Zickel nail from January 1979. 5. The mean duration of bony union in subtrochanteric fracture treated by Zickel nail was shorter than the other implants. The incidence of complications such as coxa vara, delayed union, metal breakage occurred higher in the cases treated by Kuntscher nail, Smith-Peterson nail and Thornton plate, Campression hip screw and plate. 6. Zickel nail is one of the good implant for the treatment of subtrochanteric fracture of the femur.

The ten cases of metallic failure after I-M nailing & plate fixation who were treated at depart tment of orthopaedic surgery, Soon Chun Hyang University during nine years from June, 1974 to May, 1983 were clinically analysed. The survey as summerized as follows: l. Of the ten cases, six cases were seen the breakage of plate, two cases were the loosening of screw, one case was the brakage of nail & one case was the angulation of nail. Of the six cases of plates, two cases were DCP, three cases were ordinary plate & one case was Thornton plate. 2. Of the six cases who metallic failure occurred as plate failure, five cases were the femur fractures, one case was the tibia fracture. All case who metallic failure occurred as nail failure were ferumr fractures. Of the two cases of screw loosening, one case was the fermur fracture. One case was the tibia fracture. 3. The average interval between operation and metallic failure. 1) The plate breakage was 6.3 months. 2) The screw loosening was 7 months. 3) The nail breakage was 6 months. 4) The nail angulation was 8 months. 4. The causes of failure after internal fixation. 1) The causes of plate breakage.

Several techniques are now avallable for the treatment of fractuers of the shaft of the femur. We must be aware of the advantages, disadvantages and Ilmitation of each if we are to select the proper treatment for each patient. During last decades treatment had been varied markedly from time to time and from place to place. Before Word War II, most fractures of the femoral shaft were treated conservatively either by skeletal traction or by manipulation and immobilization in a spica cast. After medullary fixation was Introduced during that war, it became popular, and until 1960 many surgeons considered it as the treatment of choice for most of these fractures. If the case is properly selected the medullary fixation is almost perfect, provlded no complications develop; convalescence can be shortened and resldual disability can be decreased. We had experienced 14 complications among the 78 cases of Kuntscher nailing from may, 1974, to May, 1980. The results are as follows: 1. We operated 78 cases with Kuntscher nail among the 121 femoral shaft fractures. 2. 14 (17.95%) complications developed among the 78 cases of the Kuntscher nailing. 3. Technical errors were incarcerated nailing with thick nail, too long nail and thin nailing. 4. Early postoperative complications within a year were infection, bendlng, bursitis, angulation and rotation. 5. Late complications after one year were proximal or distal migration and refracture.

It has been emphasized that the treatment of choice for the trochantric fracture of the femur is open reduction and rigid internal fixation to reduce complications by early ambulation. The incidence of trochanteric fracture of the femur in the young age group has been considerably increased in recent years because of increased traffic and industrial accidents. The author treated 38 cases of trochanteric fracture of the femur in the year 1974 through 1979, at the Department of Orthopaedic Surgery, School of Medicine, Soon Chun Hyang College. The results were as follows: 1. In sex distribution, 24 out of 38 were males and 14 were females. 16 cases out of 24 male patients were in the age group 20-40 and 9 cases out of 14 female were over 60 years of age. Over all mortality was 7.9%. 2. The numbers of patients of type I and III were 11 cases in each type out of 38 trochanteric fracture. 3. 26 cases out of 38 cases were treated by open reduction and internal fixation and the others were by traction and cast. 4. The applied metal devices were 3 types: Smith-Peterson nail and Thornton or McLaughlin plate, compression hip screw, and multiple pinning. 5. Mean duration of bony union is shorter in the group of open reduction and internal fixation (13 weeks) than the group of traction and cast (15 weeks). The cause of difference is that the 6 out of 9 cases of type IV and V were included in conservative group. 6. The incidece of the complications such as coxa vara, slipping screw, long nail and traction palsy occurred higher in the group fixed with Smith-Peterson nail and plate than the group fixed with compression hip screw.

Open long bone fracture is frequently difficult to reduce and maintain, especilly when there is extensive soft tissue damage. Infection, instability, malalignment and soft tissue complication often result in prolonged mobidity or failure. The Hoffmann's apparatus have merits, that can easily correct distracted, angular or rotational deformity of fracture site during early post-operative period, and stable fixation facilitates easily to the care of soft tissue injury. In addition, the affected limb can be elevated with balanced suspension, possible early exercise of neighboring joints. But we have exerienced some problems during treatment of fracture with Hoffmann's transfixation method. From February 1980 to December 1981, Hoffmann's transfixation method was employed in treatment of twenty-one patients that considered to have a poor prognosis with conversional forms of treatment. The results were obtained as follows; 1. For correction of distracted, angular, or rotational deformity, the fracture site should be reduced accurately. 2. Hoffmann pins should be transfixed as one plane and parrallel to each other. 3. Rigidity of fixation can be increased by increasing number of pins, actually three or more pins should be applied at each fragment of fracture. 4. Hoffmann's apparatus is more complex for management, more expensive and requires skillful technique compared with other external fixation apparatus. 5. The lateral view of fracture site could not be confirmed accurately due to overlapping of Hoffmann's adjustable connecting rod and bony shadow. 6. The main cause of injuries was due to traffic accidents in 17 cases (81%), involving tibia in 18 cases, femur in 2 cases and humerus in 1 case. 7. In the sixteen cases which could be assessed, the average times for external transfixation was 13.9 weeks and then followed by early weight bearing with P.T.B. cast or brace. The average time of bony union was 26.4 weeks. 8. The final result was excellent in 7 cases, good in 5 cases, acceptable in 3 cases, poor in 1 case.

A retrospective study has been made of 784 cases of road traffic casualties who were treated at the Soon-Chun-Hyang Hospital between July 1980 and December 1981. This study was conducted to find out the nature and pattern of the traffic accident from the clinical and epidemiological standpoints. In additions, the mode of injury from the road accidents were persued which might help to reduce the misdiagnosis rate. The results obtained were as follows: l. In this survey, male dominated in numbers (casualty rate, 70%). The highest incidence was in the age group between 31–40 year (26.5%). The predominance was found in younger casualties (ages between 21–50 years, 72.1% of all casualties). 2. The large number of casualties followed the rush hours. There was a peak between 10PM to midnight. The explanation for this high incidence during the hours was the hurry-up life due to midnight crufew, pedestrian's carelessness and hurry-scurry, and the negligence of traffic rules, the poor labor conditions and weariness due to drivers long continuous working hours, especially in taxi drivers. The highest seasonal incidence was in October. 3. The high incidences were in drivers and students; the drivers were the commonest victims in car passenger accidents and students were injured by pedestrians accidents respectively. The causes of high risk of injury in drivers were intimately related with their vocational aptitudes, the employment status, the driving attitudes and car maintainances; and in students, their carelessness and emotional instability, unsolved mass transportation system and their negligence of traffic rules were listed as the causative factors. 4. Over 51.8% of all casualties were injured by passenger car accidents, and 21.5% were by truck and other types of special vehicles. 5. Approximately 60% of victims were injuried in the road as pedestrian and other 40% were in the car as passengers. In general, the pedestrian injuries were more serious than those sustained in the car as passengers. 6. About 40% of total pedestrian casualties sustained injury at pedestrian's cross road. 7. About 80%of injured drivers were in the drunken state on arrival, and 20.4% of pedestrians were also heavily drunken. 8. The trauma risk was about twice higher in the front-seated passengers than the rear-seated ones in the car. In buses, the highest incidence was in the passengers seated in the front 1/3 of the seats. 9. Orthopaedic (40.5%) and head injuries (38.2%) were the commonest types of the injuries among the hospitalized casualties; about 35% of total patients had the tibial fractures. 10. Of the 784 cases, 479(61.6%) victims arrived hospital within 30 minutes after accident, and among them only 94 cases (12%) were transported by ambulance from the accident site to the hospital.

The new trial to apply the closed I-M nailing for 23 cases of long bone fracture has been used our department, loss of hematoma, further damage to periosteum and soft tissue were prevented; the risk of infection was reduced; and the early functional use of extremities without additional superflous external fixation could be made. The results obtained were as follows; 1. There was no case of non-union or other complication. 2. The average bone union rate was 26.1 weeks in femur, 22 weeks in tibia, or 11.5 weeks in forearm. 3. The advantages is simple method and be able to do early ambulation without following muscular atrophy or ankylosis. 4. The patients were satisfactory about cosmetic problem after operation. 5. The merits of this operation were the short hospitalization and early adaptation of social activity. 6. In conclusion, closed I-M nailing is method of choice for long bone shaft fracture when internal fixation is indicated and our operative is useful and simple.

A fracture of the distal tibial articular surface is fortunately an uncommon injury, since it can be exeptionally difficult to manage. The term plafond is gar'nering general acceptance since there is no anatomic name for the specific location of this fracture. The term was introduced more than 50 years ago in American orthopaedic literature to describe these injuries. The literal meaning of plafond is the underside of a floor, i.e., a ceiling, so the term refers to that portion of the distal articular surface of the tibia which articulates with the superior articular surface of the talus. It excludes the medial malleolar joint surface. Fracture of the plafond have also been called compression, pylon, Malgaigne and explosion fractures. A plafond fracture is defined as one caused primarily from direct axial compression resulting in elevation andgor displacement of all or part of the distal articular surface of the tibia, excluding isolated or combined fractures of the medial and posterior malleoli that are recognizably caused by rotational forces. We reviewed 16 cases(14 patients) of tibial plafond fractures treated at the Department of Orthopaedic Surgery of Soan Chun Hyang University Hospital during 8.5 years period from June 1974 to December 1982. The longest duration of follow-up was 5 years and 6 months, the shortest, 6 months, and the average, 1 year and 6 months. They were classified according to Moore et al., and assessed according to the criteria of Joy et al. The following results were obtained: l. Of the 14 patients, male were 12, female were 2. 2. The average age of the patients was 38 years old. 3. The most common causative injury was fall-down. 4. The most common type in radiological study was dorsiflexion type. 5. In method of treatment, operative treatment was done in 9 cases and non-operative in 6 cases. 6, The average duration of the cast immobilization in non-operative treatment was 12 weeks and operative, 10 weeks. 7. Better results were obtained by operative treatment than non-operative treatment. 8, The complications were encounted in 1 case of non-operative, 2 cases of operative treatment. 9. We agree that the accurate anatomical reduction with rigid internal fixation assures better results in the tibial plafond fracture.

Segmental Spinal Instrumentation (S.S.I.) is considered to the effective operative procedure in unstable fracture and fracture-dislocation of the thoracolumbar spine, providing improved correction effect, high rate of fusion and immediate rigid fixation which obviates the need for postoperative immobilization. Retrospective study was carried out of 24 cases of fracture or fracture-dislication of the thoracolumbar spine, There were treated with Harrington rod instrumentation and sublaminar wiring (8 cases) and Luque rod instrumentatiom and sublaminar wiring (16 cases) in Soonchnhyang University, from January 1986 to June 1988. We have analyzed the results of treatment, which were as follows ; 1. Thoracolumbar junction (T12 Ll) was most commomly involved segment (63%) and falling from a height was most common cause of injuries. 2. The most common type by Denis classification was burst fracture (38%). 3. About improvement of neurologic status by injury site and type of instrumentation, thoracolumbar junction (38.5%) and lumbar spine (35%) were better prognosis than thoracic spine (8.75%). 4. In commparison with kyphotic deformity and displacement, Harrington rod (66.4%) was better than Luque rod (58.9%) in postoperative correction. Also in total correction, Harrington rod was better than Luque rod in spite of more or less large amount of loss of correction. words : Thoracolumbar spine, Unstable fracture-dislocation, Segmental spinal instrumentation (S.S.I.)
