Email: [email protected]. Abstract: In pelvic organ prolapse, anatomical defects may occur in either the anterior, posterior, or apical vaginal compartment. The apex must be evaluated correctly. Often, defects will occur in more the one compartment with apical defects contributing primarily to the descent of the anterior or posterior vaginal wall. If the vaginal apex, defined as either the cervix or vaginal cuff after total hysterectomy, is displaced downward, it is referred to as apical prolapse and must be addressed. Apical prolapse procedures may be performed via native tissue repair or with the use of mesh augmentation. Sacrospinous ligament suspension and uterosacral ligament suspension are common native tissue repairs, traditionally performed vaginally to re-support the apex. The uterosacral ligament suspension may also be performed laparoscopically. We review the pathophysiology, clinical presentation, evaluation, pre-operative considerations, surgical techniques, complications, and outcomes of these procedures.

Hip bone, especially t he greater sciatic notch is valuable in deformed diagnostic features. The greater sciatic notch is especially bones because it is highly sexually dimorphic, is resistant to valuable in such situations because it is highly sexually damage, and thus can often be scored in poorly preserved dimorphic, is resistant to damage, and thus can often be skeletons.

  • Sexing of Human Hip Bones of Indian Origin by Discriminant Function Analysis
    JOURNAL OF FORENSIC AND LEGAL MEDICINE Journal of Forensic and Legal Medicine 14 (2007) 429–435 www.elsevier.com/jflm Original Communication Sexing of human hip bones of Indian origin by discriminant function analysis S.G. Dixit MD (Principal Investigator) *, S. Kakar MS (Guide), S. Agarwal MS (Co-Guide), R. Choudhry MS (Co-Guide) Department of Anatomy, Lady Hardinge Medical College & S.S.K. Hospital, New Delhi, India Received 5 September 2006; received in revised form 6 March 2007; accepted 23 March 2007 Available online 20 July 2007 Abstract The present study was carried out in terms of discriminant analysis and was conducted on 100 human hip bones (of unknown sex) of Indian origin. Based on morphological features, each of the hip bone was rated on a scale of 1–3 for sexing. Twelve measurements and five indices were recorded. The results of discriminant function analysis showed that the acetabular height (vertical diameter) and indices 1 (total pelvic height/acetabular height), 2 (midpubic width/acetabular height) and 3 (pubic length/acetabular height) were very good measures for discriminating sexes. Pelvic brim depth, minimum width of ischiopubic ramus and indices 4 (pelvic brim chord · pelvic brim depth) and 5 (pubic length · 100/ischial length) were also good discriminators of sex. The remaining parameters were not significant as they showed a lot of overlap between male and female categories. The results indicated that one exclusive criterion for sexing was index 3 (pubic length/acetabular height). In comparison with the morphological criteria, the abovementioned index caused 25% and 10.25% increase in the hip bones of female and male category, respectively.

  • Lab #23 Anal Triangle
    THE BONY PELVIS AND ANAL TRIANGLE (Grant's Dissector [16th Ed.] pp. 141-145) TODAY’S GOALS: 1. Identify relevant bony features/landmarks on skeletal materials or pelvic models. 2. Identify the sacrotuberous and sacrospinous ligaments. 3. Describe the organization and divisions of the perineum into two triangles: anal triangle and urogenital triangle 4. Dissect the ischiorectal (ischioanal) fossa and define its boundaries. 5. Identify the inferior rectal nerve and artery, the pudendal (Alcock’s) canal and the external anal sphincter. DISSECTION NOTES: The perineum is the diamond-shaped area between the upper thighs and below the inferior pelvic aperture and pelvic diaphragm. It is divided anatomically into 2 triangles: the anal triangle and the urogenital (UG) triangle (Dissector p. 142, Fig. 5.2). The anal triangle is bounded by the tip of the coccyx, sacrotuberous ligaments, and a line connecting the right and left ischial tuberosities. It contains the anal canal, which pierced the levator ani muscle portion of the pelvic diaphragm. The urogenital triangle is bounded by the ischiopubic rami to the inferior surface of the pubic symphysis and a line connecting the right and left ischial tuberosities. This triangular space contains the urogenital (UG) diaphragm that transmits the urethra (in male) and urethra and vagina (in female). A. Anal Triangle Turn the cadaver into the prone position. Make skin incisions as on page 144, Fig. 5.4 of the Dissector. Reflect skin and superficial fascia of the gluteal region in one flap to expose the large gluteus maximus muscle. This muscle has proximal attachments to the posteromedial surface of the ilium, posterior surfaces of the sacrum and coccyx, and the sacrotuberous ligament.

  • Curvature of the Greater Sciatic Notch in Sexing the Human Pelvis HIDEO TAKAHASHI1*
    ANTHROPOLOGICAL SCIENCE Vol. 000, 000–000, 2006 Curvature of the greater sciatic notch in sexing the human pelvis HIDEO TAKAHASHI1* 1Department of Anatomy, Dokkyo University School of Medicine, 880 Kitakobayashi, Mibu-machi, Shimotuga-gun, Tochigi, 321-0293 Japan Received 11 November 2005; accepted 26 January 2006 Abstract The maximum curvature of the greater sciatic notch and two standardized indices were cal- culated for use in the sexing of human hip bones. This was done by means of quadratic regression of the contour points of the greater sciatic notch. The new variables are not directly affected by the osteo- metric landmarks (e.g. ischial spine, tubercle of the piriformis, and posterior inferior iliac spine) which determine the greatest width of the notch. These landmarks are, however, known to be ill-defined on occasion, but nevertheless have been used to derive the conventional depth-to-width index and angles of the sciatic notch. The curvature parameter and its new indices were applied to the sciatic notch of 164 Japanese hip bones of known sex (104 males and 61 females). The accuracy of the new variables in the determination of sex was assessed and compared with that of the conventional indices and angles of the sciatic notch. The best discriminating variable was found to be the posterior angle with an accu- racy of 91%. The new parameters of the present study that represent localized shape of the sharply curved edge of the notch diagnosed sex with an accuracy of 88%. In paleoanthropological or forensic cases, using the maximum curvature of the sciatic notch and its indices may be applicable to sexing the hip bones of specimens with postmortem damage.

Jamali, M.D., Anto T. Fritz, M.D., Deepak Reddy, B.S., and John P. Meehan, M.D. Abstract: Femoroacetabular impingement (FAI) has been recently established as a risk factor in the development of osteoarthritis of the hip. Intraosseous cysts are commonly seen on imaging of FAI. In most cases these cysts are incidental and do not require specific treatment at the time of surgical treatment of hip impingement. However, in some cases the cysts may mechanically compromise the acetabular rim or femoral neck. We present a technique for treating such cysts with an all-arthroscopic technique using a commercially available bone graft substitute composed of cancellous bone and demineralized bone matrix placed within an arthroscopic cannula for direct delivery into the cysts. This technique may be of benefit to surgeons treating FAI with an all-arthroscopic technique.

Relevant articles were retrieved with PubMed using keywords such as “coccydynia”, “coccyx”, “coccyx pain”, and “coccygectomy”. Methods: Literature accumulated for this study was accumulated from PubMed using sources dating back to 1859. All sources were read thoroughly, compared, and combined to form this study. Images were also added from three separate sources to aid in the understanding of the coccyx and coccydynia. Focal points of this study included the anatomy of the coccyx, etiology and presentation of coccydynia, how to properly diagnose coccydynia, and possible treatments for the variety of etiologies. Results: The coccyx morphology is defined using different methods by different authors as presented in this study. There is no conclusive quantitative data on the incidence of coccydynia; however, there are important factors that lead to increased risk of coccydynia such as obesity, age, and female gender.
