Ex.traosseous osteogenic sarcoma is exceedingly rare although bone formation occurs commonly in different reactive processes or neoplasms. Most of this tumors occurred in the lower extremities of middle aged people. The overall prognosis is grave and local recurrence following simple local excision possibly contributes to the poor prognosis. An agressive surgical approach including major amputation is recommended as the primary form of treatment. We have experienced a case of extraosseous osteogenic sarcoma of left gluteal region at the site of therapeutic irradiation for cervical carcinoma 16 years previously.

The purpose of this investigation was to study the changes in the epiphyseal plate of growing mice by histological, histochemical and electron microscopic observation through the administration of radioactive isotope I which induced hypothyroidism. To confirm hypothyroidism induced, radioimmunoassay for triiodothyronine was carried out and the morphologic changes of thyroid gland were observed by a light microscope. Of the total of eighty ICR strain of mice, fifty received single intraperitoneal injection of 20ue/gm of radioactive isotope I which were dissolved in 0.2ml of saline. Thirty received single intraperitoneal injection of only 0.2ml of saline and these mice were used as control groups. At the end of first, second, third, fourth, sixth and eighth week after injection, both saline injected and I treated mice were sacrifised. The thyroid gland and epiphyseal plate being removed were stained with hematoxylin and eosin, alcian blue and with uranyl acetate lead citrate in each for histological, histochemical and electron microscopic studies, The results obtained are as follows: 1. The thickness of epiphyseal plate was narrowed in the I treated animals. In each zone of epiphyseal plate the cell size was reduced although the cell numbers of each cell column were not changed. This means that the reduction of thickness in the epiphyseal plate was due mainly to decreased cell size and scanty territorial matrix not to decreased cell number. 2. Alcianophility was markedly decreased ln proliferative zone, indicating that acid mucopolysaccharide diminished markedly or was absent in the proliferative zone. 3. In electron microscopic examination, the number of rough surfaced endoplasmic reticulum was decreased and their cisternae were narrowed. Decreasing tendency of dilatation and sacculation of cisternae, .reduced number of attached ribosomes on the endoplasmic reticulum, and atrophy of the Golgi apparatus with diminished number of its vesicles were noted, However glycogen particlea were accumulated. 4. The number and length of each trabeculae in the metaphysis just adjacent to the epiphyseal cartilage plate were reduced markedly, and occasionally chondrocytes which were not consumed by endochondral ossification were observed in the cartilage lattice.

In open wounds of the hand that have exposed bone or tendons, management may be difficult. Compared with conventional cutaneous pedicle flaps, the fascial radial flap transfer has several advantages : (1) one operation is required by one operating team reliably and easy to perform, (2) the appearance is not bulky, (3) the donor area is closed primarily, and (4) the hand is free for early motion of the shoulder and the elbow. One potential disadvantage is the permanent loss of the contribution of the radial artery to the circulation of the hand. One case of the fascial radial flap transfer was performed at the Department of Orthopaedic Surgery of Hanyang University Hospital, and satisfactory result was obtained.

Two cases of old unreduced radial head dislocation in children were experienced in this hospital. These were the results of neglected Monteggia fracture. Dislocated radial heads were reduced under direct vision and the anular ligaments were reconstructed. Follow up study taken 9 months and 6 years respectively after operation revealed excellent elbow motion including pronation and supination. The radial nerve palsy which had been developed in one of the two patients after injury was recovered spontaneously after reduction of the radial head without opening of the Arcade of Frohse. Then we are reporting these cases with a review of the literature.

A tibial plateau fracture was first described in the literature by Thamhayn, in 1852. It is a fracture of the proximal end of the tibia, usually involving an articular surface. The fracture is regarded as serious as it involves a major weight bearing joint and loss of function results in a high percentage disability of the extremity. Of the tibial plateau fractures treated at Hanyang University Hospital between June 1972 and August 1979, the 44 cases that could be followed for three months to two years have been analysed according to its cause, classification, treatment and result. Open reduction is indicated in anyone of or a combination of the following deformities as shown by roentgenograms: 1. a vertical depression in the plateau of greater than eight milimeters; 2. a horizontal displacement of the lateral or medial condyle of greater than four milimeters; 3. valgus or varus instability of the knee one or more milimeters in excess of that of the uninjured knee. Manipulation under anesthesia with skeletal traction is indicated in severe comminuted fracture that it is difficult to reduce with internal fixation, and open fracture that it is inevitable to delay operation. Plaster immobilization is indicated in the remaining situations except those of open reduction and skeletal traction. Anatomical considerations and a clinical end-result study of the 44 fractures emphasize the vulner-ability of the lateral tibial plateau to a valgus force on the extended knee. Among the 44 cases twenty-two (50 percent) were treated by plaster immobilization, 2 (4.5 percent) by skeletal traction, and 20 (45.5 percent) by operation. Thirty-nine cases (88.6 percent) out of 44 revealed the rating of “ACCEPTABLE” according to Hohl and Luck criteria.

In spite of numerous clinical and patho-anatomical studies made in the past, there are still different opinions concerning the machanism of low back pain. We have focused attention on the posterior structures as an alternative source of low back pain with leg radiation, so we have studied and analyzed the effect of the injection of mixture methylprednisolone acetate suspension (20-40 mg) and local anesthetic (1% procaine, 1cc) into the posterior facet joint. In this paper, the records of 41 in-patients who have chiefly compalned of low back pain wlth leg radiation and have been treated at the Departmnt of Orthopedics, Han Yang University Hospital from May, 1979 to April, 1980 were studied. The following results are recognized by observing and analyzing their chief complalnts, physical examination, x-ray findings, the effect of facet block and the follow-up studies after facet block. 1. Low back pain with sciatica was 1.9 times more common in female than male, and frequently occured In 4th to 6th decades (75.7%). 2. The abnormal findings of plain x-rays were osteophyte (35.6%), marginal sclerosis (27.1%), narrowing of disc spce (18.6%), lumbarization (11.9%), spina bifida (3.4%), and tropism (3.4%). 3. The most frequent site of abnormal posterior facet joints was at the level between 4th and 5th lumbar vertebra (42.9%), and all were on lower lumber region. 4. The range of lumbar motion was decreased in the cases of abnormal posterior facet jolnt or degenerative changes, and it was especially more decreased in the combined cases. 5. The effect of facet block was as follows; In initial assessment, 29 of 41 cases (70.7%) showed complete rellef and one month later, 16 of 29 cases (55.2%) showed continuous rolief, 4 of 18 cases (22.2%) which were followed for 3 more months showed complete relief. 6. The effect of facet block according to pain character was as follows: 20 of 26 cases (76.9%) of numbness, 5 of 6 cases (83.3%) of dull pain and 4 of 8 cases (50.0%) of radlating pain were completely relleved and a case of burning pain was partially relleved.

Replantation of a severed limb is an elective procedure and, as such, the decision to carry it out must be assessed anew in each case. The arm is progressively more valuable from shoulder to fingers, the leg, on the contrary, is progressively of less significance. Especially, the replantation of severed hand at the level of carpal bones or wrist joint is technically more difficult than at the level of forearm or arm. We have a successful case of replanted hand at the level of intercarpal joint without bony shortening.

Microsurgical compoeite tissue transplantation to date has contributed to reconstructive surgery by expediting transfer of large blocks of tissue. We have performed the first successful transplantation of microneurovascular tendocutaneous free flap from the dorsum foot to the defect of dorsum hand including extensor tendons. We considered the free flap with extensor tendons from the dorsum foot was the best donor site for functional recovery of the defect of dorsum hand. Two cases of tendocutaneous free flap transplantation were performed at the Department of Orthopedic Surgery of Hanyang University Hospital, and satisfactory results were obtained.

The increased knowledge of the cutaneous circulation of the body and refinements in surgical technique have provided the basis for the successful microvascular transfer of various muscle, skin and myocutaneous free flap. We have found the tensor fascia lata(TFL) inyocutaneous flap to be reliable one and its transfer as a free flap. The TFL myocutaneous free flap was first introduced by Hill et al in 1978 and our two cases report were first introduced in Korea. Two cases of microvascular TFL myocutaneous free flap transfer were performed at the department of Orthopaedic Surgery of Hanyang University Hospital and satisfactory result was obtained from the one of those.

Application of the Gracilis or Pectoralis Musculocutaneous Free Flap to restore finger fiexion after destruction of forearm flexors had been reported by a surgical team at the Six Peoples Hospital at Shanghi in 1976. Viability is maintained by microvascular anastomoses of the muscles artery and vein to a suitable artery and vein in the recipient site. Gracilis is suitable for obtaining the dynamic requirement of transplanted forarm flexors. We presented two cases of muscle transplantation using Gracilis Musculocutaneous Free Flap for the loss of function of the long flexors to digits due to Volkmanns ischemic contracture of which one was after supracondylar fracture and the other was infection after deep laceration on elbow. In both cases transplanted muscles survived but funtioning was well in one case and other case was not good due to the previous infection. In first case, excellent grip strength and nearly a full flexor finger movement was provided by transplanted muscles.
