Many difficult problems are encountered in the treatrnent of infected nonunion of long bone. To solve these difficult fractures, authors adopted an active approach-thorough debridement of the infected and necrotic soft tissue and bone, rigid internal fixation with autogenous cancellous bone graft and opening of the wound to ensure continuous drainage until union of the fracture. Authors treated 28 cases of infected nonunions with this method from Mar. 1980 to Feb. 1989, and the results are as follows ;1. Femur(54%) and tibia(43%) were most frequently involved sites. 2. Most of the cases(86%) were treated by rigid internal fixation and cancellous bone graft. 3. In most cases(64%), infection was controlled spontaneously by the time of bony union, but in 5 cases which showed persistent drainage, implant removal controlled the problem, and residual soft tissue and bony defect were solved by Papineau's technique or musculocutaneous flap. 4. Revision was required in 5 cases(18%) because of insercure fixation. 5. Union could be obtained in average 4.8 months, and infection could be controlled in all except 1 case.

Between Jan. 1976 and May 1987, Sixteen supracondylar fractures of the femur were treated by interlocking nailing. Of the 16 cases, 7 cases were intercondylar, 12 cases were segmental fractures of the femur, 4 cases were open fractures in the type of wound. 1. The simple supracondylar fracture involving the distal 9cm of the femur can be treated by interlocking nailing which makes firm fixation and allows early ambulation. 2. If the supracondylar fracture is accompanied with intercondylar fracture, careful reduction and transcondylar fixation by means of tibial bolt or cancellous screws are essential before the insertion of the nail. 3. The shape of the bent nail must be depended on the type of the fracture. If the nail is to be inserted into the anterolateral aspect of the distal fragment, the degree of bending of the nail is 400cm, and posteromedial is 110cm in radius. 4. The authors made several sagittal holes the at dorsum of the nail. So the screw can be easily inserted to the nail perpendicularly or obliquely, when the insertion of the screw through the transverse holes is difficult. 5. Of the 15 cases treated by interlocking nailing, 5 cases were excellent, 4 cases were good, 2 cases were fair, 4 cases were failure by schatzker assessment.

The degenerative arthritis following total menisectomy has led to consideration of the need for meniscal transplantation, this study evaluates the morphologic and histologic changes fol lowing fresh meniscal autograft and allograft in therabbits. Transplantation of the medial meniscus was carried out in two groups of 32 rabbits(autograft group=16 rabbits, allograft group=16 rabbits). The morphological and histological changes of the transplanted auto-and allografted menisci and the articular cartilage of the medial femoral and tibial condyle were observed at 2,4,6,8,10,12,22,28 weeks postoperatively. There were no significant differences between auto and allograft groups in gross appearance. Histologically, the fibrous adhesion was noted between grafted meniscus and joint capsule 2 weeks after operation, but complete healing was seen at the suture sites without rejection phenomenon at 6 weeks in both groups. There were prominent inflammatory reactions such as lymphocytes and inflammatory cells infiltration during early postoperative stages(2,4 weeks) only in the allograft group, and more prominent fibrotic reactions in the allograft group than auto-graft group. The results of this study suggest that meniscal allografts are able to adapt to the host tissues, survive within the joint environment, and provide a functional replacement for the removed meniscus, but further studies for graft-host immune response and a method to take the maintenance and deposits of graft must be needed to perform the meniscal allograft in human.

The intramedullary nailing is a good method of treatment in femur shaft fracture but it is not available in some fracture pattern or fracture level. And it is very difficult with conventional Kiintscher nailing to prevent torsional stress and fix rigidly in unstable fracture of the femur shaft. The unstable fracture by comminuted fracture or segmental fracture, nonunion and pathologic fracture needed the rigid fixation. Interlocking Kuntscher IM nailing can provide antitorsional stability, good axial alignment and prevent shortening of the fracture site, also allow early ambulation and joint exercise. We analysed 51 patients 52 cases of interlocking Kiintscher IM nailing from May 1981 to March 1988. The interlocking Kuntscher IM nailing prevents the rotational and axial roading. The interocking Kuntscher IM nailing has expanded its application in fracture pattern and fracture site. The interlocking IM nailing provides rigid fixation in severe comminuted fracture. segmental fracture, long spiral fracture, and other several unstable fractures and eliminates splinting or external supports, so it is possible doing early joint exercise. The interlocking Kuntscher IM nailing was also considered best internal fixation method in pathologic fracture or sever osteoporosis. The static interlocking for rigid fixation and the dynamic interlocking method for axial compression to fracture site during weight bearing can be adapted appropriately to fracture pattern. Radiation hazard during the interlocking nailing is not considerable.

A 26-year-old Korean man had an erythematous scaly plaque on his right thigh for fifteen years. He was diagnosed with chronic eczema and treated with topical steroid, but no clinical improvement was obtained for 15 years. Laboratory studies including complete blood cell count, urinalysis, liver and renal function test, and peripheral blood smear were normal. A biopsy specimen showed hyperkeratosis, acanthosis, and mononuclear cellular infiltration in the epidermis. These cells had a perinuclear halo and showed a Pautrier's microabscess like configuration. In the dermis, there was a band like infiltration of inflammatory cells. Infiltrates of the epidermis were negative for leukocyte common antigen(CD45) and positive for Pan T cell(CD45RO). He was treated with topical PUVA twice a week for twelve weeks. Clinical and pathological improvements were obtained. We propose PUVA may be a useful therapeutic modality to treat Woringer Kolopp disease.
