The purpose of this study is the present the short rerm result of arthroscopic reconstruction for PCL injury. Since January l990, authors have implanted the synthetic polyester ligament (ABC ligament, Surgicraft, U.K) into the substance of ruptured PCL proper under arthroscopic control. The follow up period ranged from 24 months to 61 months (average,35months). The main cause of injuries were traffic accidents in 38. Thirtyfive of patient were men and three were women, range in age from 18 to 70 years (average, 37 years). 18 were acute injury and operated at average 12 days after injury and 20 knee were chronic injury and operated at average 9 months after injury. There were 25 case that had combined ligament injuries (l2 ACL injury, ]0 MCL injury, 8 LCL injury elc). In 15 knees, the tear was in the mid substance area and in 13 it was near femoral attach site and in lO it was near tibial attach site. Postoperative result were evaluated by roentgenographic evaluation of posterior sagging, KT-20 (0 arthrometer and Lysholm knee score. Difference were improved from 12.5 mm (mean: pre.op) to 3.8m (mean: post.op) on posterior drawer test. Both knee showedminimal difference on KT-20N) study (2.l mm on 201b) at the time of follow up. The average Lysholm knee score were 84.7. By Clancy criteria, the result were exceflent 9 case (24%), good in 20 case (53%), fair in 7 case (18'Po) and failui e in 2 case (5%). On based of this study, arthroscopic augmentation with ABC ligament in PCL injury is very effective treatment but more longer follow-up and more case must he needed to accept this method.

From January 1985, to June 1986, 7 cases in which supracondylar and intercondylar fractures of the femur were treated at our orthopaedic department using the Extensile Approach for an anatomical reduction and firm internal fixstion, show successful results in follow up stuides. l. All 7 cases were type III fractures of Neers classification. 2. Among the 7 cases treated surgically using the Extensile Approach, 5 cases showed excellent and good results and the remaining 2 csses showed one fair and one failed results. 3. Probably due to the additional open proximal tibia and patella fracture and delayed surgery from trauma one case had a fair results. The case which failed wss due to ipsilsteral ligamentous injuries and a nerve injury in addition to the femur fracture and slso the impossibility of early knee joint exercise due to associated injuries. 4. None of the results of the 7 csses had any relationship with the patients age. 5. One case of postoperative skin necrosis developed around the tibial tuberosity and was treated successfully by a cross leg flap. 6. In comminuted supracondylar and intercondylar fractures of the femur, the Extensile Approach is thought to be an excellent surgical technique by means of a wide surgical field for an anatomical reduction and firm internal fixation with the repair of associated ligamentous injuries.

Congenital pseudarthrosis of the tibia was accepted as one of the most difficult disease in respect of the frequency and treatment for the orthopaedists. Since April, 1984, we experienced 3 cases of congenital pseudarthrosis of the tibia, one 2 year-old boy involved left tibia only and the other 4 year-old female involved bilaterally, obtained solid bony union in all which were treated by massive surgical management that contained vascularized bone graft and electric stimulation. Several complications were faced such as refracture, valgus deformities of the ankle, skin irritation sign, angular deformities. But refracture was healed without delayed or nonunion by simple plaster cast immobilization. The vascularized bone graft snd electric stimulation is thought to be more improved methods for the treatment of congenital pseudarthrosis of the tibia. Althought solid bony union was obtained in congenital pseudarthrosis of the tibia, periodic follow-up and adequste management must be mandatory up to the end of the bony growth.

It would be naive to assume that any operative procedure is the solution to the problem of sacral pressure sore in the field of the orthopaedic surgery. The procedures outlined here involve the creation of compound myocutaneous flaps of the gluteus maximus muscle, skin, and the subcutaneous tissue. The myocutaneous flap us- ing the gluteus maximus muscle is a vascular flap instead of a random flap, with better blood supply for healing and advantage of an increased amount of cushion effect. We present an alternative method which will provide satisfactory and substantial soft tissue coverage in sscral pressure sores.

Sensation is the key element that allows the fingertip to participate effectively in virtually all hand functions. Therefore, it is very important to restore sensation as well as well padded, durable skin coverage following severe fingertip injuries. Many ingenious operations have been described to provide the fingertip with sensate coverage. Among them, the innervated cross-finger flap, reported by Cohen et al. in 1983, is very effective and successful in reconstruction of severe fingertip injuries, We report five cases of severe fingertip injuries treated with innervated cross-finger flap. The results are as follows : 1. The level of sensory return and the functional result is excellent in those fingertips reconstructed with the innervated cross-finger flap. 2. Mean time for flap detachment is 16 days post operative and local anesthesis at outpatient department is sufficient. 3. Four of five treated patients achieved excellent sensibility with measurable two-point discrimination(mean 5.0 mm) and ability to recongnize textures and objects.

Rhabdomyosarcoma which was first described by Weber has generally been considered asan uncommon tumor. Pack and Eberhart were of the opinion that rhabdomyosarcoma represented 13.9 percent of soft tissue sarcomata. Recently it was classified as four types such as pleomorphic, embryonal, botryoid and alveolar type by many authors. We have experienced two cases of embryonal rhabdomyosarcoma, one arised within left leg and the other within right foot. The former(3 months old, female) showed tumor mass at birth, the latter(13 months old, male) showed at 1 month after birth.

Severe injuries of hands frequently expose the bone and joint due to the defect of crushing of soft tissues. Although the several methods are introduced, the treatment of bone and joint exposure of finger and hand is very difficult to control satisfactorily. From October 1986 to February 1988, we performed the pedicled skin flap in 11 cases; 9 abdominal skin flaps and 2 pectoral skin flaps. Follow up stuides showed good results. The successful surviving of flaps was accomplished in all cases and the dead bones were regenerated by the creeping substitution. Therefore this pedicled skin flap operation can be considered to be a simple and effective method in treating the bone and joint exposure of fingers.
