PURPOSE: This study was performed to evaluate the width of symphysis pubis and its radiographic appearance in different age and sex, and it was aimed to establish a radiographic diagnosis criteria for diastasis of the joint. MATERIALS AND METHODS: The width and the appearance of symphysis pubis were observed by pelvic X-ray in 92 males and 169 females who had no history of any joint disease. The mean width of symphysis pubis was calculated and data were analyzed by age, sex and parity using student t-test. RESULTS: The mean width of symphysis pubis was 2.88+/-0.71 mm in male group and was 3.24+/-0.68 mm in female group. It was 3.34+/-0.84 mm in parturient and 2.82+/-0.55 mm in nullipara and the difference between these two groups was significant (P<0.05). Osteoarthritic changes were noted in most cases over 60 irrespective of sex. CONCLUSIONS: Based on the results from this study and reported value of physiological relaxation of symphysis pubis through pregnancy and labor, a separation over 6 mm and/or a vertical migration over 3mm can be diagnosed as diastasis of symphysis pubis. This criteria would facilitate the earlier diagnosis of relaxation and separation of this joint by labor or trauma.

To investigate the mechanism of crescent formation, sequential pathologic changes from the New Zealand White rabbits with anti-GBM antibody induced GN by administration of guinea pig anti-GBM IgG were studied by light (LM), immunofluorescent (IF) and electron (EM) microscopy. Although no glomerular changes were observed in LM, swelling of the endothelial cells and the epithelial cells were noted in EM by day 2. By day 7, early and cellular crescents were evident. Proteinaceous materials and fibrins were noted in the glomerular capillary lumina (GCL) and Bowman's space (BS) associated with segmental hypercellularity. The GBM damage became progressively severe, followed by focal detachment of the visceral epithelial cells from the GBM. At day 14, fibrin strands, mononuclear cells and collagen fibrils were present between the proliferating extracapillary cells. At day 31, fibrocellular crescents were predominated. Elongated spindle cells, morphologically resembling myofibroblasts, were noted near the Bowman's capsule (BC). A degree of tubular atrophy, interstitial fibrosis, and inflammatory infiltrates increased as it did with fibrous organization of crescent. Intense linear IF staining for IgG and C3 were seen throughout the experiments along the GBM. In conclusion, the progression of crescent from an early "proteinaceous" stage through cellular, fibrocellular and fibrous stages was well documented in this study. Inflammatory cells and coagulation mechanism may activate the initiation of the GBM damage at the early stage. Activated periglomerular mononuclear cells may also cause disruption of BC which facilitates entry of activated periglomerular cells and fibroblasts into BS leading to progressive fibrous crescent formation.

A retrospective study was made of 10 consecutive patients who underwent mandibular reconstruction with PCBM from December 1994 to July 1996. Free autogenous iliac bone in the from of particulate cancellous bone and marrow was densely packed into the crib that was adapted to bridge the mandibular discontinuity defect. Frozen-treated autogenous mandibular bone, splitted autogenous rib, and titanium mesh(Dumbach, Leibinger) were used as cribs carrying the PCBM. All ten cases underwent successful healing with the formation of a continuous bony union with the remaining mandible. The rate of resorption was assessed by sequential panoramic radiographs. The mean horizontal dimension of the madibular defects was 44mm and the mean vertical dimension of the reconstructed segments was 23mm. The bony height of the reconstructed segments retained about 90% of the bony height of over a 1-year period. We confirmed that PCBM grafts were the most successful and predictable grafts in mandibular discontinuity reconstruction.

We have recently experienced a rare case of abdominal aortic injury caused by shearing force falling from 8 meter height in upright position. The patient was 43 year old and sustained Ll, L2, L5, compression fractures and both distal tibia and fibula comminuted fractures involving ankle joints. 2 years and 2 months later, marked stenosis of the distal abdominal aorta was found together with clinical manifestations of ischemia of both legs. Aorto-femoral bypass on both sides has completely relieved the symptoms.

Proximal femoral focal deficiency (PFFD) in early infancy is characteristic by quite shortening of the tight segment, flexed, abducted and externally rotated position In assciation with a stable hip which Is freely mobile. Authors experienced a case with the congenital deficiency of the femoral head. The case showed the normal femoral segment and no any other bony anomalies which cannot be Included in Aitkens or Amstutz's classification.

Melorheostosis is a rare entity while causes pain and stiffness in a limb and has an unknown etiology. It is characterized by roentgenographic appearance of melting wax dripping down one side of a candle along the major axis of long bone. The present case represents a melorheostosis of the left tibia accompanied by synovial chondromatosis in the left knee. Good result was obtained by arthrotomy of the left knee and removal of the bony masses in the joint.

Extra-capsular synovial chondroma is a rare condition in which metaplastic cartilaginous mass is formed by the cartilage nodule within the synovial connective tissue break through the joint capsule and continue to proliferate. The authors have experienced a case of giant extracapsular synovial chondroma, affecting the knee joint of 54 years old woman. A case of giant extra-capsular synovial chondroma is reported with brief review of literature.
