2.Extramedullary Versus Intramedullary Alignment Guide Systems in Total Knee Arthroplasty.
The Journal of the Korean Orthopaedic Association 1997;32(2):302-308
Fifty four consecutive total knee arthroplasties were reviewed to compare the accuracy of extramedullary versus intramedullary tibial resection guides. An extramedullary guide ( Group I ) was used in 25 cases and an intramedullary guide ( Group 2 ) was used in 29 cases. Group 1 system included the LCS knee system and Group 2 system included the Whiteside Ortholoc Advantim total condylar knee system. Preoperatively, the two groups were similar, with no statistical significant differences observed in diagnosis, alignment, and patient age. Postoperative tibial component alignment angles were similar in both group (Group 1, 0.8degrees varus; Group 2, 1.1degrees varus ). In group 1, 84% of tibial components were aligned within 2degrees of the 90degrees goal and in group 2, 83% of tibial components were aligned within the same range ( p > 0.05 ). In all cases, an intramedullary guide was used to prepare the distal femur. In femorotibial angles, with group 1 averaging 4.2degrees valgus versus 4.7degrees valgus in group 2 (p > 0.05). If the optimal femorotibial angle was defined by the range from 5+/-2, it was achieved in 76% in Group 1 and 72% in Group 2 ( p > 0.05 ). This study demonstrates no significant differences between the extramedullary and intramedullary group not only in optimal tibial component alignment angle but also in optimal femorotibial angle. This means that each system is satisfactory for the tibial side, but it is more important for the surgeon to appreciate that the indications, potential limitations and sources of errors are unique to each system and to decide which system to use according to the particular case in question.

Those unstable comminuted colles' fractures in which the dorsal or volar cortex of radius is fragmented, destroying the buttress of the bone essential to maitnain the alignment, result various residual complications. To overcome those complications, additional methods of fixation, including pin and plaster, percutaneous pinning or some forms of external fixations have been employed. Clinical analysis were made in 22 cases of unstable comminuted Colles fractures which were treated during January 1975 and September 1980 and followed-up for 6 months to 4 years and 7 months. The results were as follow: 1) The fracture occure predominantly in male (4 to 1). 2) Among the 9 cases treated with manipulative reduction followed by cast immobilization, 6 showed satisfactory results while the other 3 did not. 3 Among the 13 cases which were treated by coatinuous traction incorporated in cast, 10 showed satisfactory results and 3 did not. 4) Complications observed were; 9 cases of limited supination of affected forearm. 2 cases of ankylosed wrists. 2 cases of pin-tract infections, and 1 case of transient superficial radial nerve palsy.

It is indispensable to cover the skin defect when bone or tendon is exposed. In case of inevitable amputation of an extremity, it is possible to harvest a free flap from the amputed limb for providing coverage of the other wound. This technique allows immediate wound coverage without the morbidity of an additional donor site. We experienced an electrical burn case with inevitahle wrist disarticulation and successfully treated soft tissue defect of ankle using free vascularized flap.

5.T Cells in Cutaneous Lesions of Erythema Multiforme.

Anti-T cell monoclonal antibodies(OKT series. OKT4a, OKTSA, OKT)1) immunoperoxidase technique study for the presence of T cells in cutaneous lesions from four patients with erythema multiforme showed that most dermal and epidermal lymphoid cells were reactive with monoclonal antibodies to anti-pan T cell (l3KT11) in this semiquantitative assay. In the dermis most of the perivascular lirmphoid infiltrates were reactive with anti-helper/inducer T cell antibody, but in the epidermis and in the derrnopidermal interface the predominant cells were identified as suppressor/cytotoxic T cells. The histologic and immunopathologic changes in erythema multiforme appear to be due in part to cellular immune rnechanisms with the lyrnphocyte as the predominant effector cell. But complex interplays with other humoral immune mechanisms might be in work for the development of erythema multiforme.

A case of benign lichenoid keratosis(BLK) developed in a 25-year-old female is presented. She had two erythematous plaques with slightly verrucous surfaces on the lips for 4 weeks. A biopsy specirnen taken from the periphery of the lesion revealed a focal parakeratosis, the absence of granular cells, and hydropic degeneration of the basal cells in the epidermis. The upper dermal infiltrate composed chiefly of lymphacytes intermingled with a few histiocytes was also seen. The direct immunofluorescent study showed depositions of a few cytoid bodies and fibrin around the areas of the dermoepidermal junction. These plaques on her lips, demonstrating lichenoid tissue changes, cleared in 8 weeks from the evalution, without any treatment.

Majocchi's disease is one of chronic vascular disorders of the skin, histologically showing capillaritis with lymphoid cell infiltration. Although the hypothesis of delayed type hypersensitivity reaction against foreign antigen is proposed as the mechanism producing this condition, there are much yet to be defined. We tried to examine the lesional skin of five patients with Majocchi's disease by the direct immunofluorescence with anti-human immunoglobulins, C 3, and fibrin. As a result we found the deposition of immunoglobulins (M, and G) in papillary blood vessels in four patients, and C 3 and fibrin were found in all five patients. C3 was also found at the dermoepidermal junction in three patients. These findings suggest the posssibility that antibody mediated immunologic processes may alsobe involved in the pathogenesis of this disorder. With this observation Majocchis disease could be considered as a chronic immune vasculitis.

A clinical study was made on the 28 cases underwent prostatectomy during the 5 year-period from 1964 to 1968. The results are summarized as follows: 1. The patient underwent prostatectomy revealed increasing tendency in incidence, residual urine in average and being usually in the age range between 60 and 70 years. 2. The degree of prostatic enlargement was mostly grade 11 on rectal palpation and the removed prostate was 49. 3gm. in average weight. 3. Blood loss attributable to the operative manipulation was 1143 cc. in average. The patients underwent prostatectomy were discharged on the average 21.3 days postoperatively in which postoperative indwelling catheter was left in place for 15.3 days in average. 4. Postoperatively the convalescence was uneventful and the residual urine was disappeared or decreased markedly. 5. In the patients underwent prostatectomy via retropubic approach operative blood loss was mild and postoperative duration of indwelling catheterization was short as compared to that via the suprapubic approach. 6. No serious complication other than epididymitis developed in a few patients was observed postoperatively. 7. Suprapubic prostatectomy was found to be suitable for the patient with marked prostatic enlargement while the retropubic one yielded less tissue damage and somewhat rapid postoperative convalescence as compared to the former.
