Intramural pregnancy is a rare variant of ectopic pregnancy, which was first reported in 1924 by Perli, and only 21 cases have been reported in the literature. The pathologic diagnosis of an intramural pregnancy can be made by the myometrium surrounding the products of conception that separate it from the endometrial cavity or fallopian tubes. Recent development of radiologic ultrasonography and radioimmunoassay of the beta-subunit of human chorionic gonadotropin has markedly enhanced the ability to diagnose intramural pregnancy during very early gestation. Many reports have noted that there would be possible relationships between the intramural pregnancy and prior uterine traumatic factor-curettage, cesarean section, myomectomy, salpingectomy, and manual removal of the placenta. We experienced a 28-year-old female patient with amenorrhea for 7 weeks and sudden vaginal spotting. She underwent dilatation and curettage at 4 weeks of gestation. We report this case with a brief review of the literature.

Acrylic bone cement is now widely used in surgery for many purposes. Therefore, the effect of bone cement on the growth plate of a growing bone may be an interesting subject, particularly in the orthopedic field. The authors carried out an experiment to study the effect of bone cement on the growth plate of the bone, using 32 growing rabbits weighing from 800 to 1000 gm, which were divided into 2 main groups. In Group I, which was the control group, the growth plates were injured mechanically by inserting a Kirschner wire and a stainless screw, 1.5 mm and 2.5 mm in diameter, respectively, which were then removed. In Group II, the growth plates were also injured by the same method as in Group I, and bone cement was inserted into the holes made by the insertion of the Kirschner wire and the screw. Then the histological findings of the injured plates were studied at 2, 4, 6 and 10 weeks after injury. Following observations were made. 1. In Group I, in which the growth plates were only mechanically damaged, the histologic changes were localized only in that portion of the plate which had been injured by a wire or a screw, leaving the rest of the plate relatively normal. In Group II, the extent and severity of the injury were more wide and severe. 2. Proliferation of mesenchymal fibroblasts and deformity of the growth plate were more severe in Group II. 3. In both groups the extent and severity of growth plate injury were more marked when injured by a screw.

Purpose: We evaluated, retrospectively, twenty hips that had undergone revision surgeries because of massive pelvic osteolysis in order to determine the retention rate of acetabular metal shells and polyethylene liner exchanges.. Materials and Methods: We performed liner exchanges for massive osteolysis around stable HG acetabular cups with severe polyethylene wear in twenty-three hips, between June 1996 and May 2003. Clinical and radiological follow-up was available for 20 hips for more than 2 years. In 18 hips, we performed curettage of the granulomatous tissue and tightly packed morselized cancellous allografts into the screw holes or the peripheral rims for the acetabular osteolytic lesions. The mean follow-up period was 3.8 years (range, 2.4 to 9.3 years) and the mean of time from the primary total hip arthroplasties to the component exchanges, was 8.2 years (range, 5.6 to 12.4 years). Results: During the follow-up period, all of the hips were functioning well, and none required any subsequent repeat surgeries. Dislocations occurred three times after the repeat operations in one hip, which was treated successfully with an abduction brace. None of the hips demonstrated a progression of the pre-existing osteolytic lesions or the development of any new osteolytic lesions. At the final follow-up, none of the acetabular components demonstrated any evidence of loosening. Conclusion: Our results demonstrated that isolated liner exchanges and debridement of the granulomatous tissue, with or without bone grafting, can be an effective alternative solution to revision of the cup for massive osteolysis around well-fixed, cementless, acetabular cups in selected patients. Retention of the pre-existing cementless acetabular cup provides less intra-operative and post-operative morbidity. However, in order to determine the longevity of the retained cementless acetabular cups, further long-term studies are necessary.

Intra-uterine fracture of normal bone is extremely rare. It was reported few cases in the other contries, but it was very rare in Korea. It is difficult to distinguish it from birth fracture and the other fractures or deformities seen at birth. The authors experienced a case of intra-uterine fracture of the femur in the middle third of the shaft, with abundant callus formation in infant without serious injury to the mother.
