This is a report of three cases of congenital dislocation of the knee with the chief complaint of extension contracture knee, seen at the Severance Hospital Department of Orthopedic Surgery from January 1975 to the present time(April, 1978). In the first case, the dislocated knee was associated with congenital dislocation of the hip and congenital club foot. Family history revealed that the elder brother of the patient had died of complications of premature birth. The second case appeared to be an isolated congenital dislocation of the knee, without associated anomalies or relevent history in the family. In the third case, the dislocated knee was associated with adducted thumbs and genu valgum, as well as congenital dislocation of the hip and congenital club foot, although family history was irrelevant. In all the cases roentgenographic examinations revealed in the lateral view that the tibia was displaced anteriorly in relationship to the femur. Two cases were treated by four or five successive corrective castings, each lasting one week to ten days. It is contemplated that the third case will also be treated by a simillar corrective cast immobilization. Following this course of treatment, each of the two dislocated knees was completely reduced and the original limitation of flexion improved. Experience with these two cases suggests that good results may be obtained with conservative treatment in congenital dislocation of the knee. A brief review of the literature is submitted.

Reconstruction of extensive soft tissue defects of the lower extremity, especially when complicated by open fracture and bone loss, is usually a difficult problem for the plastic surgeon. Many methods have been devised to treat these conditions Musculocutaneous flaps add a valuable surgical alternative that bring vascularized cover to the defects, and the free microvascular transfer of these flaps gives the surgeon an added dimension of versatility. The latissimus dorsi is an extremly reliable musculocutaneous flap with a long, large-caliber vascular pedicle, so that dissection of the muscle can be performed with relative ease. The size of the latissimus dorsi muscle lends itself to coverage of large defects. While these characteristics appear to make the free latissimus dorsi musculocutaneous transfer ideal in many circumstances, it has some disadvantages. At the recipient site, the flap is ofter too bulky, and donor-site closure requires skin grafts if the flap is wider than 10cm. These skin grafts on the posterior thorax seriously detract from the final appearance of the donor site. The authors have experienced 12 cases of reconstruction of extensive lower extremity soft tissue defect in which the latissimus dorsi muscle alone was transferred and covered with a split-thickness skin graft. This method improves the recipient-site contour by decreasing the bulk of the flap and it also improves the donor-site appearance. We described technical considerations in each case and the advantages of free latissimus dorsi muscle flap and skin graft for the reconstruction of extensive soft tissue defect in the lower extremity.

A study of the effectivity and reliability of discectomy and anterior interbody fusion with autogenous iliac bone graft for spondylogenic and discogenic back pain and/or radiating pain has been done on 48 patients who had been hospitalized at Severance Hospital between January 1976 to June 1978. To the preoperative symptoms and signs such as the presence of back pain, sciatica, muscle atrophy, sensory change, motor change, spinal motion, deep tendon reflex, S.L.R., knee-chest compression test and Patricks test were checked, and after the operation, the same symptoms and signs were checked as to how they were improved or not. The age range of patients was 17 to 64 years and 40% of them were in the 3rd decade. Before the operation, for the confirmation of the origion of the back pain, we did perform dynamograms for instability and myelograms for root compression and spinal stenosis. The approach to the lesion was mainly retroperitoneal with anterior approach. Bony union after the operation was decided by a plane roentgenogram or clinical signs, and a dynamogram in some cases. The following results were obtained from analysis of the cases studied. 1. Eighty percent of the cases showed improved back pain in postoperative 3rd day and 83% showed improved sciatica in 6 months after the operation. 2. During the operation, the operative dislcogram could be done to verify the level of the lesion and the disc degeneration, disc protrusion, bony spur, narrowing of the joint space and instability during the operation could be confirmed in direct vision, so we could perform the operation for the accurate lesion. 3. Rather than the posterior approach, the anterior approach could allow all the remnants of the disc to be removed thoroughly. 4. In anterior interbody fusion, the strut of iliac bone was firmly impacted with two blocks, so its stability could be maintained, and patient could be mobilized earlier. 5. Clinical union of bone grafts was obtained in between 3 to 6 months and 96% of the cases showed bony union in 9 months. In 14 cases of two level fusions, the bony union was delayed compared to the one level fusion. 6. After the operation, the patient could return with the brace on to the office only within three months. The brace was taken off after the bony union was verified by plane roentgenogram and dynamogram.

To achieve full pronation and supination after fracture, many authors have pointed out the importance of the length of the bones, the absence of the angulatory deformity and rotational deformity, maintenance of the interosseous space and the curves of the radius, especially the lateral bowing of the radius. Over the years many methods of open reduction and internal fixation or the closed method have been advocated and comparisons have been made between the groups treated by the conservative method and open reduction and internal fixation. The authors have reviewed 108 cases of the fracture of the shaft af the forearm bones from 1 January 1971 to 31 March 1979 which were treated in Department of Orthopedic Surgery, Severance Hospital, Yonsei University College of Medicine. The following results were obtalned from analysis of the cases studies. 1. There was no difference between the conservative treatment group and the open reduction and internal fixation group for fractures of the radius or ulna alone in fracture heallng time, but there was delay in fracture healing time in the open reduction and internal fixation group compared to the conservative treatment group for fractures of both forearm bones. 2. Satisfactory functional results were shown in the open reduction and internal fixation group rather than in the conservative treatment group. 3. Angulatory deformities were shown in 47.2% of the conservative treatment group and 14.8% of the open reduction and internal fixatlon group. 4. In selected cases, an Evan's tuberosity view was taken and rotational deformities were shown in 30.0% of the conservative treatment group and in 8.8% of the open reduction and internal fixation group. 5. There was no difference between the conservative treatment group and the open reduction and internal fixatlon group in non-union rate and delayed union rate.

Excess hair growth in unwanted areas may result from heredity, endocrine disease, or drug therapy. Conventional methods of hair removal include shaving, wax epilation and chemical depilatories that frequently cause side effects such as contact dermatitis and that also have temporary effects. Electrolysis is a well-established medical method for permanent destruction of terminal hair follicles. However, this method is tedious and efficacy has been reported to range from 15-to-50% permanent hair loss. The evolution of the laser use for hair removal continues a year after Food and Drug Administration (FDA) approval of the first laser for these applications. The authors have experienced hair removal utilizing a long-pulsed alexandrite laser. This laser system employs the principle of thermokinetic selectivity, a revolutionary concept. The principle of thermokinetic selectivity involves the use of lasers with pulse durations below the thermal relaxation on a the large target such as the hair folllicle (40-100 msec), and significantly longer than the thermal relaxation time of smaller structures of the same chromophore (melanin) in epidermis (3-10 msec). The study was based on 76 patients treated with 20 msec pulse duration laser set to energy densities of 17-21 J/cm2. Treated areas included arms, legs, beard-chin, upper lips and bikini lines. Gross observation showed leaching of hair color, decresed size of the skin pores, easily broken hair shafts, and elimination of hair. Therefore, it can be assumed that the majority of hair follicles were destroyed by this procedure, Side effects included intermediary risk of hyperpigmentation and blister. Over 80% of treated patients were satisfied with the results. As the process of research and clinical application continues, we need the long-term results of this laser system to ensure its efficacy.

The use of artificial skins for full thickness wounds is an accepted technique, but unfortunately the take rate is low and the aesthetical result is not acceptable. The freeze-drying treatment of allogenic tissues can destroy cells with preserving the structural organization of extracellular matrices, permitting allogenic transplantation. In this study we investigated a new method to process the allogenic skin for transplantable allogenic dermis and this dermis was evaluated in a full thickness wound model. The results are as followings; 1. After treatment with NaCl and SDS solution and then with freeze-drying method, the allogenic dermis shows acellular dermal matrix with preserved normal extracellular matrix. 2. This allogenic dermis became completely incorporated into the wound without evidence of rejection or replacement by scar tissue. 3. The take rate of thin autografts overlying the allogenic dermis that were applied simultaneously was comparable to take rate of autograft alone. 4. The reduction in secondary contraction by allogenic dermis treated wounds was significant. 5. After grafting with cultured keratinocytes, the degree of epithelial coverage was 70% at 2 weeks. In conclusion, the allogenic dermis processed with our method displayed lack of antigenicity, and rapid revascularization. This allogenic dermis can permit simultaneous engraftment of an overlying STSG or cultured kerationocytes, reduce secondary contraction and improve cosmesis of full thickness wounds.

In many cases the breast reconstruction surpasses the goal of a normal breast mound appearance in clothing and achieves a result that, in time, may look almost normal in the unclothe state. Breast reconstructions with autologous transverse rectus abdominis myocutaneous (TRAM) flaps are well known to produce the most aesthetically excellent results. the pedicled to TRAM flap cannot be used in high risk patient such as obese or smoking patients due to partial flap necrosis. But, the free TRAM flap have more robust blood supply and less donor site morbidity than the pedicled TRAM flap and is therefore the currently preferred technique in western. However, the free TRAM flaps has a problem related to the anastomotic failure which has been reported as high as 6% to 10%. Moreover many Korean women have smaller sized breast than western women and have no risk factors compromising flap circulation. So the single pedicled TRAM flap can be safely used for breast reconstruction without any flap necrosis. 60% of the elevated flap area has a sufficient volume to mold a new breast that matches with the contralateral breast and the unneccessary distal portion of the flap that has the marginal circulation can be resected. In this study we review our 20 consecutive cases of breast reconstruction using the pedicled TRAM flap and have a conclusion that the pedicled TRAM flap produce an aesthetically acceptable new breast in Korean mastecotmy patients without any flap necrosis or donor site morbidity.

A clinical study of the tibial fracture was made on patients, total 234 tibias, who were treated at the Department of Orthopedic Surgery, Paik Hospital, Inje Medical College from 1974 to 1979. The results were as follows: 1. The ratio between male and female was 5. 5: 1 and majority was found between 3rd decade and 5th decade. 2. In the shape of fracture, commiuted fracture, transverse fracrure were common in order. 3. The most common cause of these fractures was traffic accident and the ratio between open and closed fracture was 1:2. 4. The most common associated injury was the fibular fracture. 5. More complications ensued in open reduction and internal fixation than in closed reduction. of 50 cases, which were treated by open reduction and internal fixation, delayed union in 32 cases (64%) and infection in 11 cases (22%) resulted. 6. In the treatment of open comminuted tibial fractures with skin and soft tissue loss or marked displacement, Hoffmans external fixation method and pin and resin external fixation method bad good results, Early motion of adjacent joint, easy care of wound and rigid fixation were obtained by it.
