The purpose of this study was to analyze the change of morphologic pelvis according to age and gender. Pelvis AP(anterior-posterior) projection were taken from 382 individuals (men: 194, women: 188) at the age of twenty and older. We measured four values of pelvis using CR (computed radiological system) including maximum pelvic breadth (MPB), sacral breadth (SB), transverse diameter of pelvic inlet (TD), and distance between femoral heads (DFH). Average (t-test, ANOVA) and Pearson correlation were calculated for comparison. While there was no significant difference of gender in case of MPB, significant differences were observed in SB (men 97.76 mm, women 102.00 mm), TD (men 138.0 mm, women 149.79 mm), and DFH (men 141.94 mm, women 150.39 mm). The DFH values were negatively correlated with the age (men r=-0.280, women r=-0.207). The morphological changes of pelvis were measured high in the men of 50's and in the women of 60's and 70's. The SB, TD and DFH were greater in the women than in the man. As the ages get higher, the deviation of pelvis were gradually increased, which indicates that the morphological changes of pelvis with respect to the age reflects an aging process.

A 7-year-old neutered male Korean domestic short-haired cat was referred to our clinic to treat constipation which had persisted for 6 months. The rectal examination revealed narrowing of the right lateral portion of the pelvic canal. A reduced pelvic canal diameter by pelvic fracture malunion was revealed on radiography. The pelvic canal diameter ratio measured from preoperative was 0.68. Based on rectal and radiographic examinations, constipation caused by pelvic canal narrowing was confirmed. Pelvic symphyseal distraction-osteotomy and iliac wedge osteotomy were performed. An iliac osteotomy of the ilium was performed to ease the pelvic symphyseal distraction. After the symphysis was split longitudinally, pelvic symphyseal distraction was maintained by using a spacer made of poly-methyl-methacrylate. The osteotomy of the ilium was fixed using a bone plate and screws. Increased pelvic canal diameter was confirmed on post-operative radiography and the postoperative pelvic canal diameter ratio was 0.91. The patient received antibiotics, NSAIDs, crystalloids and Lactulose for post-operative care. The cat recovered normal defecation abilities and did not have constipation at one week postoperatively. No episodes of constipation persisting longer than 6 months have been reported by owners in previous studies. Pelvic symphyseal distraction osteotomy and iliac wedge osteotomy may prove to be a useful surgical procedure to treat pelvic canal stenosis that is caused by pelvic fracture malunion.

The purpose of this study was to investigate effects of three pelvic floor muscle (PFM) exercises on the thickness of PFM and transverse abdominal muscle (TrA), the internal oblique muscle, and the external oblique muscle. The PFM and trunk muscles were measured using ultrasonography in 4 conditions.rest, conventional PFM contraction (Ex A), PFM contraction with hip adductor contraction (Ex B), and PFM contraction with real-time ultrasound imaging (Ex C). The thickness of PFM in Ex C showed a significantly more decrease compared to rest and others (all comparisons, p<.05). The thickness of TrA in Ex C showed a significantly more increase compared to rest and others (all comparisons, p<.05). This study would recommend the use of PFM contraction with real-time ultrasonographic imaging to improve women's incontinence.

The purpose of this study was to investigate the effects of pelvic adjustment on low back pain and spino-pelvic parameters in middle-aged women. Thirty-eight middle-aged women with chronic low back pain were randomly assigned to the pelvic adjustment (n = 20) oruntreated control (n = 18) group. Pelvic adjustment interventionswereperformed four times a week for 8 weeksin the former group. At baseline and after 8 weeks, the back pain and back function were evaluated using the visual analogue scale (VAS), Oswestry disability index (ODI), and back flexibility. Additionally, the spino-pelvic radiographic parameters and serum C-reactive protein (CRP) levels were assessed. After 8 weeks, the VAS, ODI, and back flexibility significantly improved in the pelvic adjustment group compared with the control group. It was found that the changes from baseline in the lumbar lordotic angle, sacral slope, pelvic crest unleveling, and femoral head height inequality were significantly greater in the pelvic adjustment group than in the control group. There were no significant changes in the pelvic incidence or serum CRP levels in either group. In conclusion, pelvic adjustment has beneficial effects on chronic low back pain and back function, suggesting that the effects of pelvic adjustment on back pain may at least in part result from changes in the spino-pelvic alignment.

Pcrosonimr westermani is a lung fluke of humans that Is usually found in the lunes but may be fecund elsewhere in many unusual locations. A case of pelvic paragonimiasis was found incidentally by surgical intervention of inamatov disease and myoma uteri. She was a 51-year-old Korean woman complaining of lower abdominal pain and intermittent vaginal spotting. Numerous Porosonimus ova were observed in the reseated omentum in the pelvis after total abdominal hysterectomy. It is suggested that pelvic paragonimiasis may be one of causative agents of pelvic inflammatory disease.

Unstable pelvis ring trauma can accompany urologic injuries such as bladder, ureter, or urethral injuries. In very rare cases, testicular dislocation can accompany a pelvic ring injury. Testicular dislocation causes pain, but can be regarded as the pain caused by pelvic ring injury. If not detected early, testicular dislocation may result in gangrenous testes. The authors report a case of pelvic ring injury with testicular dislocation.

Traumatic pelvic injuries usually include high-energy crush injuries and are associated with significant morbidity and mortality. Mortality rates range from 6% to 15% and increase to 36%-54% in cases of fractures that result in increased pelvic volume. Therefore, retroperitoneal hemorrhage can spiral and progress to hemorrhagic shock. Pelvic hemorrhage most commonly occurs secondary to disrupted pelvic veins or fractured bones, and 10%-20% of cases involve arterial injuries. Owing to extensive bleeding and limitations of surgery for pelvic hemorrhage, interventional treatment is at the forefront of pelvic hemorrhage management. CT is an accurate indicator of active hemorrhage in patients with pelvic trauma that affects the diagnosis and management, including interventions. Identification of the site of hemorrhage is necessary for focused interventional treatment. The current trend toward a more conservative approach for treatment of pelvic trauma and advances in interventional radiology in the field of pelvic trauma may favor widespread use of interventional treatment for patients with pelvic injuries. In this review, we discuss therapeutic modalities available to the interventional radiologist and common angiographic treatment strategies and techniques.

The objective of this study was to evaluate tire effects of modified triple pelvic osteotomy(TPO). The procedures of modified TPO were composed of two iliac osteotomies and a pubic symphysiotomy at a tittle. Medical records of modified TPO treatment on 36 dogs and of unilateral TPO on 7 dogs were reviewed on the basis of signalment, body weight, operation time, Healing time of osteotomy sites and complications from October 2002 to September 2004. The values of clinical status and hip dysplasia, Norberg angle, percentage of femoral head coverage and pelvic diameter from radiographs taken preoperative, immediately postoperative, 2, 4, 8, 12 and 24 weeks after operation, respectively, were measured. In .unilateral TPO, the dogs could start standing without assistance from $3.0\pm1.0days$ and walking from $8.3\pm0.6days$ (n=3). Mean clinical grade before and 24 weeks after surgery were $2.2\pm0.42$(n=6) and $3.5\pm0.7$ (n=2), respectively. Mean operation time was $107.3\pm38.9$ minutes (n=4). In modified TPO, the dogs were seen to staff standing without assistance from $4.9\pm3.7$ days and walking from $7.3\pm4.8days$ (n=25). Mean clinical grade before surgery and 24 weeks after surgery were $2.3\pm1.5$ (n=27) and $3.2\pm0.7$)(n=9), respectively. Postoperative clinical grade significantly improved against preoperative clinical grade (P<0.01). Mean operation time was $143\pm42.8$ minutes (n=24). This was shorter than time f3r twice unilateral TPO. By comparison with preoperative values, postoperative mean radiographic grade, percentage of femoral head coverage and Norberg angle measured at the recheck time point significantly increased (P<0.01). Mean postoperative pelvic diameter was significantly larger than preoperative pelvic diameter in modified TPO (P<0.01) but not in unilateral TPO. These results indicated that modified TPO was effective technique for the treatment of hip dysplasia in dogs.

This study measured the exposure dose during abdominal-pelvic CT exam which occupies 70% of CT exam and tried to propose a protocol for optimized exposure dose in abdomen and pelvis without affecting the imagery interpretation. The study scanned abdomen-pelvis using the current clinical scan method, the 120 kVp, auto exposure control(AEC), as 1 phase. As for the newly proposed 2 phase scan method, the study divided into 1 phase abdomen exam and 2 phase pelvis exam and each conducted tube voltage 120 kVp, AEC for abdomen exam, and fixed tube current method in 120 kVp, 100, 150, 200, 250, 300, 350, 400 mA for pelvis exam. The exposure dose value was compared using $CTDI_{VOL}$, DLP value measured during scan, and average value of CT attenuation coefficient, noise, SNR from each scan image were obtained to evaluate the image. As for the result, scanning of 2 phase showed significant difference compared to 1 phase. In $CTDI_{VOL}$ value, the 2 phase showed 26% decrease in abdomen, 1.8~59.5% decrease in pelvis for 100~250 mA, 12.7%~30% increase in pelvis for 300~400 mA. Also, DLP value showed 53% decrease in abdomen and 41~81% decrease in pelvis when scanned by 2 phase compared to 1 phase, but it was not statistically significant. As for the SNR, when scanning 2 phase close to heart, scanning 1 phase close to pelvis, scanning and scanning 1 phase at upper and lower abdomen, it was higher when scanning 2 phase for 200~250 mA. Also, the CT number and noise was overall similar, but the noise was high close to pelvis. However, when scanning 2 phase for 250 mA close to pelvis, the noise value came out similar to 1 phase, and did not show statistically significant difference. It seems when separating pelvis to scan in 250 mA rather than 400 mA in 1 phase as before, it is expected to have reduced effect of exposure dose without difference in the quality of image. Thus, for patients who often get abdominal-pelvic CT exam, fertile women or children, this study proposes 2 phase exam for smaller exposure dose with same image quality.
