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.

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.

Porencephaly is relatively rare condition defined by an defect or a defect or cavity in the cerebrum owing to a developmental malformation or to a destructive lesion. Fory-five porencephaly patients diagnosed by Brain CT were clinically analyzed and the following results were obtained. 1) By the age group presenting initial symptoms, the peak incidence was from 1 month to below 3 years old. 2) In initial symptoms, seizure, spastic weakness, headache were showed in order of frequency. But 7 cases (15.5%) were asymptomatic. 3) The latency of diagnosis after presenting initial symptoms from the symptom onset time to 10 years. 4) The subsequent symptoms were as follows: spastic weakness, speech disturbance, gait disturbance, mental retardation, sensory loss and seizure showed independently or combined. 5) As etiologic factor, 21 cases (46.7%) were congenital, 16 cases (35.5%) were post-traumatic or post-operative and 8 cases (17.8%) were perinatal. 6) The prognosis was seen various from mild to severe. Out of 45 cases, 29 cases (64.4%) were no complications. But the prognosis in patients with post-traumatic or postoperative etiological factors was poor. With the advent of brain CT and the resultant capability of detecting structural defect and cerebral lesions responsible for epilepsy or focal neurologic signs, porencephaly was seen to be readily recongizable by CT examination. Since porencephaly is a significant contributor to the spectrum of CNS lesion and benign condition, ist recognition is important in determining prognosis and therapy.
