Purpose: Dislocation is the second most common cause of failure, after implant loosening, in revisional THA (Total hip arthroplasty), and its evaluation and treatment still remain controversial issue. This study was undertaken to evaluate the risk factors after THA using the posterolateral approach and posterior soft tissue repair. Materials and Methods: Between January 1998 and May 2003, 211 consecutive primary total hip replacement arthroplasties using the posterolateral approach and posterior soft tissue repair were performed by the same surgeon. To compare the dislocation groups (6 cases) with the non-dislocation groups (205 cases), we randomized 120 of the non-dislocation cases. The risk factors for hip dislocation were categorized into patient factors and surgical factors. Patient factors included gender, age, preoperative diagnosis, underlying systemic disease, and alcoholic history. Surgical factors included position of the component (acetabular version and inclination, femoral anteversion), leg length discrepancy, and sum of anteversions of the cup and stem. Their parameters were measured on postoperative radiographs. Statistics were performed with Fishe`s Exact test and T test. Results: Dislocations occurred at an overall incidence rate of 2.8% (6/211cases). There were 4 (1.9%) cases of anterior dislocations and 2 (0.9%) cases of posterior dislocations. Dislocations occurred on average at postoperative day 6.1 and all dislocated hips were reduced with the closed method, except for one case that was treated surgically. There was no statistical significance in patient factors between the two groups, except for neurologic disease and alcoholic history. However, the sum of the acetabular and femoral anteversions in the anterior dislocation group was larger than that of the non-dislocation group by approximately 19 degrees. Conclusion: Our results demonstrated that by using the posterior approach and repair of soft tissue, the posterior dislocation rate after total hip replacement arthroplasty can be reduced and the sum of the acetabular and femoral anteversions had more influence on dislocations after THAs than did either anteversion alone.

The purpose of this study are to delineate the temporal and spatial changes of bone mineralization at the distraction gap and adjacent parent bone, and to investigate the effect of microaxial dynamization on regenerate bone healing and on development of regional osteopenia at the adjacent parent bone, during callotasis. Sixteen Korean adult mongrel dogs underwent bilateral tibial lengthening by callotasis. To the right hindlimbs, no dynamization was applied and served as control group (group I, and axial elastic dynamization was conffered to the left hindlimbs (group II). Bone mineral density(BMD) was measured by dual X-ray absorptionmetry(DXA) at immediate post-operative day, post-operative 12 day, 22 day, 36 day, 50 day, 65 day, and 85 day. Quantitative computed tomogram(Q-CT) was also taken after sacrifice to analyze temporal changes of mineralization pattern in the distraction gap. The following results were obtained; 1. In both group I and II, the BMD was lowest at the interzone in the distraction gap and increased linearly toward the corticotomy surface. This pattern did not change with time until the consolidation of the distraction gap, but the difference of BMD between the interzone and adjacent parent bone decreased with progress of consolidation. 2. During the distraction period, BMD increased progressively at the distraction gap and adjacent parent bone in both group I and II. During consolidation period, although BMD of the distraction gap still increased progressively, that of the adjacent parent bone decreased progressively in group I; the more distant from the corticotomy surface, the more decreased the relative BMD. in group II, the decrease in BMD of the adjacent parent bone was less than that in group I which was statistically significant in mid-consolidation period. In conclusion, the new bone in the distraction gap during callotasis appeared to form in bilateral direction with linear gradient from interzone toward corticotomy surface. Dynamization during callotasis not only stimulated regenerate bone healing in the distraction gap, but also prevented the occurrence of transient regional osteopenia at the distant part of the adjacent bone during midconsolidation period.

Favre-Racouchot syndrome(nodular elastosis with cysts and comedones) is a peculiar complication of solar elastosis in which comedones, follicular cysts, and nodules of altered elastic tissue occur mainly sround the orbits, on the cheeks, on snd around the nose, and oceasionally in other exposed areas, but sornetimes on the neck or behind the ears. We present a typical case of the Favre-Racouchot syndrome in a 66 year old man with maxillary cancer. The patient had numerous yellowish cysts and black topped comedones located on the forehead, around the orbits and the nose, on the neck, and also behind the ears of 5 years duration. The histopathology of the lesion showed dilated pilosebaceous openings and epitheliaI lined cysts filled with layered keratin in addition to pronounced solar elastosis.

Histiocytic medullary reticulosis is a rare, uniformly fatal, acute disease of the reticuloendothelial system. The disease is associated with fever, malaise, weakness, weight loss, lymphadenopathy, hepatosplenomegaly, jaundice, and purpura. Common laboratory findings are severe anemia, leukopenia, and thrombocytopenia. A 49-year-old male patient is described who had multiple purple nodules and tumors in the skin. A biopsy taken from a skin lesion showed a diffuse proliferation of atypical histiocytes in the dermis and subcutaneous tissue.However, erythrophagocytosis of these atypical histiocytes was not seen.

Cryptococcosis is an acute, subacute or chronic infectian caused by the encap sulated yeast Cryptococcus neoformans. The case of Cryptococcosis is a 2 5/12 year-old boy with involvement of the skin, lungs, liver, spleen, lymph node and central nervous system is reported. He has suffered from fever, nausea., vomiting and multiple skin lesions for a month. Thcre were various cutaneous lesions consisting of papules, pustules, nodules, crusts and ulcers on the scalp, face, back, buttocks and both extremities. Diagnosis was confirmed by the clinical characteristics, histopathologic findings and culture of the C. neoformans from cerebrospinal fluid and marcerated skin tissue. He was successfully treated with combination of Amphotericin B and 5-fluorocytosine.

The purpose of this study was to evaluate the results of various types of opponensplasties which have been performed for the last 15 years. For the patients who had median nerve injury with or without ulnar nerve injury, we usually transferred the ECRL or ECRB to restore thumb opposition and Huber s procedure were usually done for thumb hypoplasia. With the criteria outlined by Sundararaj and Mani, postoperative function of 27 hands from 23 patients who underwent the opponensplasty from March 1981 to March 1995 were evaluated. The results from each etiology group were analyzed by the same criteria. Also subjective opinion of the patients about the scar were investigated by our own criteria. The analysis from overall 27 hands yielded 19 excellent (70.4%), 4 good (14.8%), 3 fair (11.1%), and 1 poor (3.7%) results with Sundararaj and Mani s criteria and 1 excellent (3.7%), 14 good (81.5%), 3 fair (11.1%), and 1 poor (3.7%) results about the scar. In 11 patients with nerve injury (median nerve with or without ulnar nerve injury), 7 excellent and 2 fair results were yielded by the ECRL or ECRB transfer, 1 excellent by Phalen-Miller's procedure, and 1 excellent by Burkhalter's procedure. In 8 patients with congenital hypoplastic thumb, 7 excellent results were yielded by Huber's procedure and 1 excellent by the ECRB transfer. In 8 patients with residual poliomyelitis or brachial plexus injury, the ECRB transfer yielded 3 excellent results. However, 2 good and 1 fair results were obtained by Bunnell's procedure; and l good, l poor by Camitz's procedure. In summary, the ECRL or ECRB transfer in the patients who had neuropathy, such as median with or without ulnar nerve injury, brachial plexus injury or residual poliomyelitis; and Huber's procedure in congenital hypoplastic thumb were thought to be one of the useful methods for the restoration of the thumb opposition.
