Richter's type of obturator hernia with Howship Romberg sign: a case report

Obturator hernia is a rare type of pelvic hernia in which intraperitoneal contents protrude through the obturator foramen and is most commonly found in females. It accounts for about 1% of all abdominal hernias and possesses a great diagnostic challenge due to the non-specific symptoms and meagre clinical signs. Hereby we report a case of obturator hernia in an nonagenarian emaciated fragile old lady who presented with features of acute Intestinal obstruction and was diagnosed using computed tomography as right sided obturator hernia and eventually was taken up for emergency laparotomy. The herniated segment was resected and anastomosis was done with primary closure of the defect. Postoperative period was uneventful and the patient was discharged on postoperative day 7.

Predicting the shape of the obturator foramen in the surgical treatment of stress urinary incontinence in women

The aim of the study was to study the possibility of predicting the shape of the obturator foramen depending on the shape of the pelvic bone cavity in the aspect of the surgical treatment of stress urinary incontinence in adult women. Materials and methods. 61 preparations of the female bone pelvis were studied. A pelviometric form was developed, according to which the linear and angular parameters of the pelvis and obturator foramen, indices of the pelvic cavity and obturator foramen were evaluated. A discriminant analysis was applied to classify the shapes of the obturator foramen. Results. Based on the calculated pelvic cavity indices, the shape of the pelvic cavity was determined: narrowing to the bottom, cylindrical and widening to the bottom. Using discriminant analysis, a model was developed to predict the shape of the obturator foramen, depending on the shape of the pelvis. Two main forms of the obturator foramen are distinguished: triangular and elliptical. It was found that the triangular form of the obturator foramen is most characteristic of the cylindrical form of the pelvic cavity and to a lesser extent of the downwardly tapering form. The ellipsoidal shape of the obturator foramen predominated in the downwardly expanding pelvic cavity. It is also shown that a narrow under-pelvic angle is characteristic of the downward pelvic cavity and a wide under-pelvic angle is characteristic of the downward dilating pelvis. Conclusion. The presented index of the lateral deviation of the ischial tubercles makes it possible to determine the shape of the pelvic cavity: narrowing to the bottom, cylindrical and dilating to the bottom. The method of discriminant analysis provides a high degree of certainty in predicting the shape of the obturator foramen, depending on the shape of the pelvic cavity.

SEX DETERMINATION FROM HIP BONE FRAGMENT IN DHANBAD, JHARKHAND

The current study used discriminant function analysis to derive a model for determining sex from an adult hip bone fragment (distal ischio-pubic portion). The discriminant function obtained was DF = .76*SYL +1.60*SYW + 4.36. *DOF – 24.88. The three predictors [maximum vertical length of symphyseal surface (SYL), maximum width of symphyseal surface of pubis (SYW), and maximum diameter of the obturator foramen (DOF)] accurately categorised 90.0 % of the cases. Cross-validated ndings revealed 86.7% accurate categorization. This preliminary research's ndings indicate that these three factors lead to gender discrimination in the study participants. Again, discriminant functions are population specic. Using the discriminant function on a sample from the population of Dhanbad, Jharkhand, the hipbone may be sexed quite accurately. This metric analysis may be utilised for the population's hipbone fragments.

Irreducible Overlapping Pubic Symphysis Dislocation Managed with Distraction Osteotomy of the Contralateral Superior Pubic Ramus: A Rare Case Report

Introduction: Overlapping pubic symphysis dislocation (OPSD) or a locked pubic symphysis is a compression of the pelvic ring with the intact pubis trapped into the contralateral obturator foramen. Reduction can be difficult and contralateral suprapubic osteotomy is a good way to address the irreducible OPSD. The technique has only been discussed thrice in the available literature. Case Report: We report the case of a 26-year-old man who had his right pubic ramus entrapped within the contralateral obturator foramen, having an overlap of >4 cm with associated ipsilateral sacroiliac joint (SI joint) disruption and urethral injury. When all the maneuvers of closed and instrumented open reduction failed, we performed a superior pubic ramus osteotomy on the left side and unlocked the incarcerated right pubic ramus. The osteotomy site was stabilized with a 6-hole recon plate and SI joint was stabilized with a 6.5mm percutaneous sacroiliac screw. The patient underwent delayed urethral repair at 10 weeks after the index surgery. At 3-year follow-up, the patient did not report any pubic discomfort, urinary and sexual problems. Conclusion: Locked OPSD is a rare injury and is frequently associated with sacroiliac and urethral injuries. Distraction osteotomy of the contralateral superior pubic ramus is a viable option for irreducible cases. Keywords: Lateral compression injury, locked symphysis pubis, superior pubic ramus osteotomy, overlapping pubic symphysis dislocation.

Gross Anatomical Studies on the Hind Limb of the West African Giraffe (Giraffa camelopardalis peralta)

This study on the gross anatomy of the West African giraffe’s hind limb was aimed at investigating the unique morphological features and number of bones making up this region of the skeleton. Two (2) adults obtained as carcasses at different times after postmortem examination were prepared to extract the bones via cold water maceration for use in the study. The appearance of the ossa coxarum and its features presented similarities to that of the horse. However, differences were evident in the convex cranial border of the ilium, small less prominent coxal tuber, and wider interval between the opposite sacral tuber and an oval obturator foramen. Common features reported in most species such as the gluteal line and psoas tubercle were absent. The long femur presented proximally; the greater trochanter connected obliquely via the trochanteric crest to the lesser trochanter. The supracondyloid fossa, obliquely directed medial condyle, and trochlea with two unequal ridges were presented distally. The fibula was absent while the tibia was typical of ruminant presentation with one popliteal line and no muscular lines on its caudal surface. The five (5) tarsals were arranged three proximally and two distally. One (1) metatarsal (3rd and 4th fused) presented two condyles that anchor two (2) digits with 3 phalanges and 3 sesamoid bones each. The total number of bones making up the hind limb was accounted to be 45. In conclusion, this study has provided a baseline data for further biological, archeological, and comparative anatomical studies.

Bowel obstruction in obturator hernia: a challenging diagnosis

The obturator hernia is a rare pelvic hernia that presents as bowel obstruction caused by the presence of an intestinal segment, more often ileum passing through obturator foramen. This type of hernia accounts for 0.5-1.4% of all hernias. We reported the clinical case of a 74 year old woman with no previous surgical interventions, presented to ER with abdominal pain and distension, features of intestinal obstruction, which she had experienced for previous three days. A CT scan revealed a right jejunal, obstructed obturator hernia. The patient underwent an emergency surgical intervention with emergency exploratory laparotomy and repair. This case was presented as obturator hernia was a rare type of hernia due to its diagnosis, which is often unclear with non-specific pain radiating to legs mimicking neurological symptoms. A prompt suspect based for the non-specific symptoms is crucial for the diagnosis. Surgical management depends on early diagnosis and it is the only possible treatment for this pathology.

The path to minimizing instability in developmental dysplasia of the hip: is Capsulorrhaphy a necessity or a futile habit?

Background To evaluate and quantify the intraoperative effect of capsulorrhaphy on the deep seating of femoral head within the acetabulum as measured by medial joint space, a surrogate measure of acetabular-head contact. Methods In order to determine the exact effect of capsulorrhaphy, we prospectively scrutinized a consecutive sample of 18 patients with unilateral dysplastic hips aging > 18 months and followed them for a period of at least 12 months. The procedure of open reduction is described in detail. Two pediatric orthopedists carried out the operations from August 2014 to January 2019 at a tertiary pediatric hospital. Intraoperatively, AP radiographs of the pelvis were obtained before and after capsulorrhaphy. The distance between the inferomedial edge of the proximal femoral metaphysis and the lateral edge of the obturator foramen was recorded. To determine if there were differences in medial joint space due to capsulorrhaphy, a generalized linear model was run on the study sample. All patients were followed for at least 12 months to determine the rate of re-dislocation. Results Mean age (±standard deviation) of the participants was 37.5 (±24.7) months. All cases underwent Salter osteotomy, 5 cases needed femoral shortening (27.8%) and none needed derotational osteotomy. Capsulorrhaphy lead to a statistically significant decrease in the mean medial joint space from 1.59 cm before (95% CI: 1.12–2.05) to 0.76 cm after (95% CI: 0.50–1.02) the capsulorrhaphy (P < 0.001). When we took the effect of age into account the corresponding figures were 1.47 (95% CI: 1.22–1.75) and 0.67 (95% CI: 0.39–0.94), respectively (P < 0.001). After follow up periods of 1 to 5.5 years, none of the patients experienced instability or re-dislocation. Conclusions Capsulorrhaphy, independently, of age was associated with a 1-cm decrease in the mean medial hip joint space and a more deeply seated femoral head. Furthermore, this study presents a successful experience with capsulorrhaphy to prevent hip instability.

Obturator hernia: case report

Obturator hernia, protrusion of abdominal content through the obturator foramen, is a rare type of abdominal wall hernia. Late patient presentation is associated with significant morbidity and mortality. We present rare case of obturator hernia causing small bowel obstruction in a 65-year-old-female patient. She presented with crampy abdominal pain, nausea and vomiting of three days duration. She was diagnosed with acute surgical abdomen and managed surgically at Arsi University College of health sciences, Assela, Ethiopia. Intraoperative finding revealed left-side obturator hernia, which is an extremely rare occurrence. Despite delayed presentation, our patient had smooth postoperative recovery. Obturator hernia is exceedingly rare, and it poses a diagnostic challenge as signs and symptoms are often nonspecific, making a preoperative diagnosis difficult. So, it should be considered as differential diagnosis in elderly patients presenting with acute surgical abdomen.
