Implant materials, for examples, plaster of Paris, Bone cement and ceramics which are used experimentally to regain shape and function, act as a scaffold for bone growth and contribute to the healing processes at bone defect developed by trauma, infection and other causes. Therefore, the effect of plastei of Paris on the bone defects of adult rabbits may be an interesting subject, particularly in the orthopedic field. The authors carried out an experiment to study the effect of plaster of Paris on the bone defect, using 30 adult rabbits weighing fmm 3000-3500 gm, which were divided into 3 main gmups. (Each group was composed of 10 adult rabbits.). In Group 1, which was the control group, made a defect at the proximal metaphysis of the tibia, 6 mm×6 mm×6 mm in size, using a drill bit and filled by hematoma spontaneously. In Group II and Group IU, a defect was also made by the same method as in Group I and a piece of Gelfoam or plaster of Paris was inserted into the bone defect respectively. Then we studied the healing processes of the bone defect by sacrifying animals of each group at 6th and 12 th week after operation. The results of this experiment were as follows. 1. New bone formarion in the bone defect was poor in group I and Gmup Il, but it was good in Group III. 2. The plaster of Paris, filling into the defect, was absorbed and removed from the site of implantation continuously and stimulated the new bone formation. 3. The Gelfoam in Group II was more rapidly absorbed than plaster of Paris and didn't stimulate the new bone formation.

A fracture of the femoral neck in a young adult differs from the same fracture in an older patient in the following respects; 1. A relatively uncommon injury. 2. A significant difference in the severity of trauma. 3. A less satisfactory result. At the point of view, we studied the femoral neck fcartures in 15, 20- to 50-year-old patients. The aims were to analyze why these fractures occur in young adults, and what results can be expected after internal fixation. The results were as follows; 1. Common in men (3:1). 2. 80% (12/15 cases) of the fractures were caused by severe trauma. 3. The 3 cases (20%) were associated with the other fractures. 4. The factors infuencing the clinical results and complications in our study; a. Severity of trauma. b. Degree of displacement. c. Existence of posterior comminution. d. Time interval between accident and operation. 5. The multiple pinning got the more rigid fixation and diminished the rate of fixation failure. 6. All cases were achieved good to acceptable reduction. 7. Satisfactory functional results were achieved in 93.3%. 8. The rate of avascular necrosis was 15.4% (2/13 cases). It is concluded that the most of femoral neck fractures in younger patients occur because of the significant trauma. In our study, the incidence of avascular necrosis was not greater than in order patients. Therefore, to get as good a result as possible it seems important to perform the anatomical tion and rigid internal fixation with or without bone graft.

Fracture of the tibial shaft is one of the most common fractures of the long bones and frequently followed by malunion, delayed union and nonunion. We experienced the cases of further increase in the angulation after clinical union of the tibial shaft fractures treated by conservative method. So we analyzed 39 cases of tibial shaft fractures which were followed up from 12 weeks to 37 weeks after clinical union in adults. The results were as follows; l. 7 of the 39 cases(18%) showed the increase in the angulation, and all of them were male. 2. Increase in the angulation occurred more frequenlty in the comminuted fractures than simple fractures. 3. The increment of angulation was more marked in group of patients with higher angulation at the time of clinical union. 4. Increase in the angulation occurred more commonly in the cases not associated with fibula fracture than in the cases associated with fibula fracture. 5. Further increase in the angulation was less common in the cases in whom early weight bearing with PTB cast was started.

The courses of the progression in the fibrous dysplasia are characterized by asymptomatic progression or spontaneous regression in some cases after the growth has ceased and the aims of treatment for a fibrous dysplasia are prevention of the pathologic fractures and correction of the deformities. The osteogenic potentiality of the cambium layer in the periosteum and the beneficial effect on the osteogenesis of the impregnating bone graft with autologous red marrow are well documented. We experienced an extensive fibrous dysplasia with cortical thinning and pathologic fracture and it was managed with subperiosteal combined xenograft of Kiel bone with autologous red marrow for the induction of cortical thickening and prevention of the pathologic fractures because of the inoperability of curettage due to extensive lesion over the entire femur, limitations in obtaining large amount of autogenous cancellous bone for the graft and lack of the facilities of the bone bank. This subperiosteal composite xenograft with autologous red marrow for a fibrous dysplasia gave an excellent result of a remarkable cortical thickening and we think this can be a type of management for a entensive fibrous dysplasia. So we are reporting this case with bibliographic reviews.

Wide resection is an acceptable alternative to amputation for the management of primary sarcomas of the long bones or pelvis. The resected bone can be debrided of gross tumor tissue, autoclaved, and than replaced to reconstruct the limb anatomically. The procedure can be combined with prosthetic reconstruction of adjacent joints with sufficient strength to allow early unprotected weight-bearing. We had an experience of a large segmental defect in the shaft of the humerus after wide resection due to.a low grade malignant chondrosarcoma without extension to the surrounding soft tissues and this case had been managed by reimplantation after autoclaving the locally resected segment and autogenous iliac bone graft with a sound union and the favorable functional outcomes. So we are reporting this case with bibliographic reviews as a possible method of reconstruction for the management of the segmental defect which was produced by a local resection for a low grade malignancy.

Since osseous healing in the fracture of the femoral neck is carried out by endosteal bone formation, the size of contact area of the fracture fragments and impaction are of prime importance. It is not uncommon to be faced with the problem of back out of the internal fixation devices during healing period. It seems unnecessary to emphasize the benefit of sliding to close the gap between the fracture fragments. We report a retrospective study of 25 cases of the femoral neck fractures treated by closed reduction and fixation with multiple Knowles pins, paying particular attention to the amount and duration of sliding back out of the fixation devices and relating these to the final results of fracture union. Our clinical study led us to the following conclusions; 1. The shortoning of the femoral neck over 3mm occurred in 16 cases(64%) out of 25 cases. The average amount of back out of Knowles pin is 6mm. 2. Most of the shortening occurred during the first 8 weeks after surgery and extrusion of the nail is frequent findings in unstable fractures and osteoporoses. 3. Backing out over 12 weeks after surgery was associated frequently with delayed union and non-union. 4. Collapse or shortening is nceessary to promote a bone to bone contact and bone healing.

Speckled lentiginous nevus is a clinical variant of nevus-cell nevus first described by Stewart et al. in 1978. It is characterized by small, dark hyperpigmentated speckles superimposed on a tannish-brown background. The speckled areas show varying histologic patterns ranging from nevus incipiens to junctional or compound nevus. The back ground shows histologic features of Ientigo simplex. Recently, we observed clinical and histological features of 5 cases of speckled lentiginous nevi. The age of onset ranges from birth to infancy, The locations are face, thigh, back and scapula. One has zosteriform distribution in upper extrernity, chest and back. Histologic features of speckles are junctional or compound nevus. We suggest that the origin of dark speckles may be from the tannish-brown background, lentigo simplex.

Posterior chamber intraocular lenses were implanted into 40 eyes with inadequate capsular or zonular support by securing both haptics of the lenses to the sclera at ciliary sulcus with 10-0 prolene sutures. Our follow-up of 36 eyes with scleral fixated posterior chamber intraocular lenses ranged from 2 months to 8 months(average 4.6 months). At the last follow-up visit. 31 eyes(86%) had a vision of 0.5 or better. Mean refractive error was -1.15 +/- 1.13D. which was -0.67 +/- 0.99D more myopic than predicted (p<0.05). Measurement of anterior chamber depth showed deeper than the control group of posterior chamber intraocular lenses without scleral fixation suture(4.18 +/- 0.42mm, 3.96 +/- 0.29mm, respectively), but which was not statistically significant(p>0.05). Additionally, the difference of postoperative axial length between two groups was not statistically significant(23.39 +/- 0.87mm, 23.42 +/- 0.75mm, respectively). In 4 eyes(ll %), minor intraoperative bleeding oceured but was absorbed spontaneously without any sequelae. One eye(3%) of minimal decentration of PCL, one eye(3%) of subluxation of PCL, and one eye(3%) of exposed scleral fixation suture were noted, but no serious postoperative complication, such as corneal edema, glaucoma, persistent uveitis, or retinal detachment was detected.

PURPOSE: To describe the MR features of intraspinal cysticercosis. MATERIALS AND METHODS: Medical records and MR images of four cases of intraspinal cysticercosis were retrospectively reviewed. The MR findings were described with regard to the location and signal intensity of the lesions, contrast enhancement, presence or absence of associated intracranial cysticerci, and other findings. RESULTS: There were three cases of subarachnoidal form and one case of intramedullary form. Cysticerci of subarachnoidal form in three cases were located in retromedullary space at C2 level, anterior to cord at C1 -C6 levels, and lumbosacral area, respectively. The signal intensities of the lesions were same as those of CSF. Localized arachnoidal enhancement was found in all three cases. In one case there was a large area of high signal intensity within the spinal cord on T2 weighted image suggesting either ischemia secondary to vascular compromise or inflammatory edema. All of these three cases accompanied intracranial cysticercosis. Intramedullary cysticercosis in one case was shown as a single I cm cystic lesion at C2 level, which showed hypointense signal on T1 weighted image, hyperintense signal on T2-weighted image, and signet-ring-like enhancement. This lesion did not accompany intracranial cysticerci. CONCLUSION: lntraspinal cysticercosis manifested as single or multiple cysts within either spinal cord or subarachnoid space, and were frequently associated with arachnoiditis.
