Various anatomical defects have been described in the surviving co-twin who had stillborn, macerated monozygotic co-twin with disseminated intravascular coagulation. The suggested mechanism was the transfer of emboli or thromboplastic materials of dead fetus to co-twin through placental vascular anastomoses. Multicystic encephalomalacia is the condition defined anatomically by the presence of multiple cavities in the great part of both cerebral hemispheres. The most common pathogenesis is circulatory disturbance caused by neonatal asphyxia during the perinatal period. We experienced two cases of monozygotic twin with deceased co-twin at 26 weeks, 33 weeks of gestation and confirmed the diffuse multicystic encephalomalacia by cranial ultrasonography and MRI in a surviving co-twin. Only one patient has been followed who showed spastic cerebral palsy and severe mental retardation. We report two cases of multicystic encephalomalacia in a surviring co-twin with a intrauterine fetal death and its related literatures.

The dual muscle flap (Latissimus dorsi+ Serratus anterior muscle) based on the thoraco-dorsal vascular system for limb reconstruction has been infrequently reported. We have used this flap as a free flap for limb reconstruction in four patients (3 cases in lower linb, 1 in upper limb). A Latissmusi dorsi muscle or musculocutaneous flap and Serratus anterior muscle flap were used and all cases healed satisfactorily. The indications for this flap are to resurface two separate defects simultaneously or to resurface very large defects. It has the advantage of requiring anastomosis of one vascular pedicle only. This flap is particularly suitable for resurfacing defects wider than their length, in relation to the long axis of the limb.

Benign chondroblastoma of bone is a relatively rare primary bone tumor which develops in the 2nd to 3rd decade involving the epiphysis of the long bone. The over-all reported cases of the world have been lesser than 400 after determining the entity as benign chondroblastoma in 1942 by Jaffe and Lichtenstein. A case of the benign chondroblastoma with involvement of the greater trochanter of the femur of a 19 years old boy is presented. The conclusive diagaosis was led by histological examination. Considerable new bone formation and bony spicules which might be derived from previous multiple puncture made us to confuse with osteogenic sarcoma. The specimen was composed of reddish brown hemorrhagic and fragile tissue with scattered either yellowish gritty calcified material or bluish translucent ones. The postoperative course has been smooth and there has been no evidence of recurrence for postoperative 15 months.

Extraosseous tuberculosis of the extremities is relatively rare even in the wide spread incidence of bone and joint tuberculosis. And few reports about extraosseous tuberculosis of the extremities have been published in the literatures. Eight cases of the extraosseous tuberculosis of the extremities were experienced at the Department of Orthopaedic Surgery, National Medical Center, from 1975 to Sep. 1979. Five out of 8 extraosseous tuberculosis were tenosynovitis and the others were bursitis in location. All cases were surgically excised and combined with antituberculous chemotherapy, and primarily cured.

Degenerative spondylolisthesis, which occurs frequently in middle-aged women, is a disease that causes canal stenosis of the lumbar spine and low back pain. Although the clinical features have been described characteristically, its pathogenic mechanism and therapeutic principles are still to be clarified. Some investigators have claimed that the disease originates from morphologic abnormalities of laminae and facet joints or that it is primarily due to degeneration of the intervertebral disks and degenerative changes of the facet joints. We selected two groups of patients retrospectively. The one was a group of patient who had normal findings on their magnetic resonance imaging(Group I ) and the other was a group of patients who showed degenerative spondylolisthesis at L4-5 and had been managed surgically(Group II ). We measured the total lordosis from Ll to S 1 and segmental lordosis of L3-4, L4-5 and LS-S 1 in both groups by Cobbs method. In group 3, we measured the degree of slippage of the L4 vertebral body and investigated the associated congenital anomalies of the lumbosacral vertebra on simple anteroposterior and lateral radiographs in both groups. And we measured the facet joint angles of the L3-4, L4-5 and L5-Sl at both side on MRI. Then we analysed the results statistically and got the following conclusions. 1. In Group I, total lordosis decreased significantly. The segmental lordosis of L4-5 and LS-S1 decreased, too, but the segmental lordosis of L3-4 increased. 2. The facet joint angles of L4-5 in Group I increased significantly in both sides. 3. The intercrestal line was lower in Group I than in Group II. 4. The degree of slip was not related with the facet joint angles of L4-5.

Horizontal tear of the meniscus occurs most commonly in older patients. The tear begins initially with a simple horizontal cleavage which divides the meniscus into superior and inferior leaves resembling a fish mouth and which may become a flap or more complex tear with time if subjected to repeated injury. Thirty-four patients(36knees/40menisci) with horizontal tear of the meniscus, treated with arthroscopic partial meniscectomy except in 3 extensive tears at Ulsan University Hospital from Jan. 1993 to Jun. 1996, were analyzed to investigate the factors that may be associated with this type of meniscal tear, and the results were as follows; 1. The tears commonly occurred in labor workers(61.7%) and without obvious trauma history(67.6%), and the average age at the time of surgery was 44 years. 2. The most common site of the tear was posterior horn of the medial meniscus (62.5%). 3. The 40 horizontal tears consisted of 12 horizontaVcleavage(30%), 3 horizontaVflap(7.5%), and 25 horizontaUdegenerative complex tears(62.5%). 4. Degenerative changes were frequently noted in both arthroscopy(69.5%) and roentgenography (72.2%).
