The fixation methods that can be used for unstable posterior pelvic ring injuries have undergone many innovative changes due to the recent development of surgical and imaging techniques. After understanding the appropriate indications of first and second sacroiliac screw fixation and spinopelvic fixation, innovative methods, including the trans-sacral screw fixation, posterior tension-band plate fixation, and the S2AI screw, would be chosen and applied. Considering the anatomical complexity and proximity to the surrounding vessels and nerves in the posterior fixation, the safe zone according to the fixation options should be well understood in preoperative planning. Moreover, the functional reduction of the posterior pelvic ring through the reduction and fixation of the anterior lesion should be achieved before placing the implant to reduce the number of malposition-related complications.

This is a case of a 51-year-old, Filipino, multipara, presenting with a five-month history of gradually enlarging pelvoabdominal mass. Initially assessed with multiple myoma, a total abdominal hysterectomy with bilateral salpingooophorectomy and excision of pelvic mass were done. Histopathology report of the mass showed Rosai-Dorfman Disease (RDD) and immunohistochemical stains, CD68 and S100, were both confirmatory. RDD within the pelvic cavity is an extremely rare occurrence with only seven reported cases globally on a wide-literature search. This paper describes the clinical presentation, imaging, management and histopathology of the case. The objective is to increase awareness on the pelvic manifestation of RDD and to provide health care professionals with additional knowledge for diagnosis and management of similar cases.

Objectives: This is a descriptive study to determine the origin of abnormal obturator arteries, the drainage of abnormal obturator veins, and if any anastomoses exist between these abnormal vessels in Filipino cadavers. Methods: A total of 54 cadaver halves, 50 dissected by UP medical students and 4 by UP Dentistry students were included in this survey. Results: Results showed the abnormal obturator arteries arising from the inferior epigastric arteries in 7 halves (12.96%) and the abnormal communicating veins draining into the inferior epigastric or external iliac veins in 16 (29.62%). There were also arterial anastomoses in 5 (9.25%) with the inferior epigastric artery, and venous anastomoses in 16 (29.62%) with the inferior epigastric or external iliac veins. Bilateral abnormalities were noted in a total 6 cadavers, 3 with both arterial and venous, and the remaining 3 with only venous anastomoses. Conclusion It is important to be aware of the presence of these abnormalities that if found during surgery, must first be ligated to avoid intraoperative bleeding complications.

Researching anatomy of renal pelvis for removal renal intrasinal calculi. From 1/1998 to 6/1999, 44 kidneys of adult were researched by classical dissection, plastic cast, selective arteriogram and 45 cases of renal intrasinusal calculi were removed: 30 lower partial nephrectomy, 3 upper partial nephrectomy, 12 pyelonephrectomy (resnick or extended Gil - Vernet) with the result: non nephrectomy, non mortality. The placement of pelvis and advantage, disadvantage of each operative technique in this procedure has been shown.

Pelvic nonunion is very difficult to treat. According to the nonunion site, anterior or posterior surgical approach should be used selectively. And if the nonunion site is located in both anterior and posterior, both anterior and posterior surgical approach should be used. We report a case of testicular necrosis after ilioinguinal approach used as a anterior approach to pelvis to treat pelvic nonunion developed as a result of unstable pelvic ring injury.

In a study of 20 primary tumors of osseous pelvis proven pathologically, computed tomographic appearance wasanalysed and correlated with the conventional radiographic appearance in terms of destructive patterns, tumor-bonemargins, internal architectures, periosteal reaction and extents of the tumors. CT was invaluable for theassessment of the extent of tumors/associated extraosseous soft tissue masses and the detection of the internalmatrix within the tumor. We found the additional information about the extent of soft tissue mase in 4 cases (20%)and about the internal matrix in 5 cases (25%). According to the analysis of the patterns of corticaltransgression, grade III was absent in benignancy, but in 6 cases of malignant tumors. CT is less useful in theevaluation of the periosteal reaction and tumor-bone margin in flat bony lesions, not tumor-soft tissue margins.Certain types of tumor behavior characterizing the lesions under discussion may be helpful in diagnosis.

Ureteral stent insertion is a common procedure in the urologic field. Although the migration of ureteral stent is uncommon, it can be serious complication. We report the migration of Thermo-Expandable Stent (Memokath) from upper ureter to renal pelvis, and which was managed by surgical removal after failed rigid and flexible ureteroscopic manipulation.
