Computed Tomograms of 45 patients with or without lung mass were reviewed to determine the characteristics of the major and minor fissures. Also pulmonary vascular distibutions were analyzed to localize each pulmonary lobe. The results were as follows; 1. Each major fissure area was imaged frequently as lucent band, less frequently dense band. 2. The minor fissure areas were imaged as oval or triangular lucent zones. The oval or triangularlucent zones were as same frequency. 3. Avascular planes without above mentioned lucent zones were also correspond to minor fissure areas. 4. Slices of avascular zones were observated between pulmonary arteries to posterior segment or apicoposterior segment of upper lobe and to superior segement of lower lobe on both lungs.

Twenty cases of pulmonary metastases from pathologically proven stomach carcinoma were studies with specialreference to the clinico-radiological findings and the grades of cell-differentiation of stomach carcinoma. Theywere calssifed into five types based on the pattern of chest X-ray findings according to the reportedclassifications of metastatic pulmonary carcinoma. The radiological appearance of pulmoanry metastases formstomach carcinoma was didffferent from that of usual pulmonary metastatic cancers. The Type IV metastatic form(Type IV-Progressive increasing interstitial lung markings and then infiltration of pulmonary parenchyme with orwithout evidence of pleural effusion.) was most commonly seen in stomach carcinoma particularly in poorlydifferentiated cell type and more associates with respiratory symptoms than others.

Melorheostosis is a rare disease entity of bone with an etiology and pathogenesis. It cause pain and stiffness in an affected limb, and dense bone formation along the side of bone resembles the flow of candle dripping. Two cases of the disease involving left hand and wrist, and right lower leg are reported with the review of literature.

70 cases free fiap were performed from March 1978 to July 1985. The donor fiap were dorsalis pedis flap in 34 cases, groin flap in 8 cases, osteocutaeous flap in 3 cases, gracilis flap in 17 cases, and latissimus dorsi flap in 8 cases respectively. The success rate was 90% in total including partial success. The causes of failure were 2 cases infection necrosis, and 1 case kinking of drain vessel. The gracilis and latissimus dorsi myocutaneous flap were very satisfactory method for the reconstruction of the upper extremity flexion power, especially in the case of Volkmann's ischemic contracture. The neurovascular dorsalis pedis flap was regarded as excellent method for the heel pad reconstruction, and tactile sensation reconstruction of the hand.

The authors performed the interfascicular nerve grafting in the gap of injured nerves using the microsurgical technique to obtain the accurate coaptation of the fascicles. The authors experienced the 33 cases(26 patients) of the interfascicular nerve grafting in the median(11), ulnar(9), radial(2), common peroneal(3) and digital(8) nerves at the Department of Orthopaedic Surgery, College of Medicine, Kyung Hee University from Jan. 1980 to June 1984. The patients were followed up from 12 to 26 months (average 20 1/2 months). The following results were obtained; 1. The shorter the length of the donor nerve and the younger the age of the patients are, the better the recovery of the nerve function is. 2. The medial and lateral cutaneous nerves of forearm as donor nerve are suitable as well as the sural and superficial radial nerves. 3. The end result of each patient was evaluated by Seddon's classification. The excellent motor recovery was 72.0% (18/25) and the excellent sensory recovery was 81.8% (27/33). 4. The interfascicular nerve grafting is an excellent method in treating the widely separated,severed peripheral nerve injury.

We studied two hundread cases of replantations-61 cases of major limb replantation and 139 cases of finger replantation. 53 of 179 patients had multiple amputation. The most common cause of amputation was cutting-machine injury and the next one was belt and roller injury. The patients were followed than 6 months, ranging 6 months to 5 years and 10 months, averaging 36 months. The success rate of replantation is 86.9%(53/61) in the amputated limbs and 80.6%(112/139) in the amputated digits. Main causes of failure were tissue crushing, vessel thrombosis, long ischemic time, and amputation wound infection. Common complications were infection (25 cases), delayed union(7 cases), nonunion(2 cases), bleeding tendency and hematoma formation due to systemic heparinization(5 cases). We used Seddon's classification to assess the recovery of the nerve function of the replanted limbs and digits. 84.6 % of success cases of limb replantation presented the excellent result in the motor fuction recovery and 89.1% also presented the excellent sensory recovery. 89.8% of the success cases of the digit replantation showed the excellent result in the sensory recovery. The factors influencing the functional recovery of the replantation surgery were mechanism of injury, ischemic time, surgical technique, numbers of anastomosed vessels, ratio between anastomosed artery and vein, and wound infection. This analysis demonstrated that strict selection of the indication or the replantation is the first step in the limb and digit replantation surgery.

Buoy flap was useful method for soft tissue defect, bone defect or bone and soft tissue defect. Also the buoy flap could use monitoring for blood flow. The advantages of the buoy flap were long length of perforating cutaneous branch, large diameter of Peroneal vessel, transposition in same leg and the another advantage was that the fibula is the long, straight and mainly cortical bone. To obtain successful result of buoy flap, one must have the anatomic concept for vascular pattern (straight branch, proximal oblique branch, branch from muscular branch, distal oblique branch), relationships with surrounding muscles (between Peroneus m. and Soleus m., Through Peroneus m., through Soleus m.) and length of perforating branch. So, we studied total 19 person, 22 cases of buoy flap, who were admitted and took the operation at Kyung Hee University College hospital, from October 1985 to March 1987.

In certain low-grade malignant tumors and tumors that have a frequent recurring tendency in long bone, the wide segmental resection can cure and prevent to recur. But a main problem is prserving of bony continuity in bony defect site due to wide segmental resection. The traditional bone graft have the high incidence in non-union, malunion, delayed union, bony reabsorption, stress fracture despite long immobilization and stiffness of adjacent joint. We have attempted to overcome these problems by using a microvascular technique to transfer the fibula with its peroneal vascular pedicle as a living bone graft. From February 1980 to August 1986, we tried the reconstruction of wide bone defect after segmental resection at long bone tumors in 10 cases, using Vascularized Fibular Graft. The types of tumors were malignant fibrous histiocytoma in 2 cases, fibrous dysplasia in 2 cases, simple bone cyst in 1 case, giant cell tumor in 2 cases, cavernous hemangioma in 2 cases and multiple exostosis in 1 case. An average follow-up was 48 months, average bone defect after wide segmental resection of lesion was 12.3cm.These all cases revealed the good bony union in average 4.5 months, the free ambulation without external immobilization was got in average 6 months. And we got the wide range of motion of adjacent joint without recurrence and serious complications.
