OBJECTIVES: Malreduction in the axial plane (malrotation) following tibial fracture surgery is often undiagnosed. A few clinical and radiographic methods have been proposed for measuring tibial rotation intraoperatively, yet have failed to match the accuracy of computed tomography (CT). The aim of this study was to develop radiographic tools for future intraoperative assessment of the tibial shaft rotation profile. METHODS: The setting was a laboratory computerized analysis...

PURPOSE: Femoral component malrotation in total knee arthroplasty (TKA) is clinically proven to cause dissatisfaction and impaired function. This study is an attempt to characterize the tibiofemoral kinematics following femoral malrotation in posterior stabilized (PS) TKA. It was hypothesized that internal malrotation would introduce the most pronounced changes. METHODS: Six fresh-frozen cadaver specimens were mounted in a kinematic rig. Three motion patterns were applied with the native knee and following PS TKA (passive motion, open chain extension, and squatting) while infrared cameras recorded the trajectories of markers attached to femur and tibia...

Pediatric phalangeal fractures are extremely common, especially among toddlers and older children/adolescents involved in sporting activities. The physical examination must include an assessment for deviation and malrotation. In addition, concomitant injuries must be assessed for such as tendon and/or neurovascular injuries. Plain radiographs are typically sufficient to make the diagnosis and determine the treatment. The majority of pediatric and adolescent phalangeal fractures can be treated with immobilization...

This study is to prospectively evaluate the efficiency of sonography for volvulus diagnosis in neonates with clinically suspected intestinal malrotation.A total of 83 patients with suspected intestinal malrotation who underwent detailed abdominal sonography and upper gastrointestinal contrast study were included. Malrotation was characterized by inversion of the superior mesenteric artery (SMA) and superior mesenteric vein (SMV) in sonographic examination. The "whirlpool sign" of Color Doppler Sonography was recognized as a characteristic for malrotation with volvulus...

Extra-renal calyces are a rare anomaly of the renal collecting system, characterised by the presence of calyces and pelvis outside the renal parenchyma. It may also be associated with other anomalies, such as renal ectopia, fusion and malrotation. We describe an unusual case of extra-renal calyces with six long calyces arising from a suspected multicystic dysplastic kidney that was successfully managed laparoscopically.

Because most malrotations of the small intestine are thought to occur during repackaging, the location of the intestine should vary less during physiological herniation than afterwards. Examination of serial sagittal sections of 27 embryos and fetuses (gestational age six to nine weeks; crown-rump length 15-45 mm) during herniation showed that the jejunum and ascending colon passed through a small opening of the hernia sac at the levels of the stomach and pancreas in 16 specimens. Below the pancreas, a definite mesentery extended between the ascending and descending colon in the abdominal cavity...

Midgut malrotation and incomplete rotation are common causes of neonatal intestinal obstruction. At end of 10 week of intrauterine life, cecum will be placed in subhepatic region temporarily and descends to right lower quadrant by eleventh week. Arrest of cecum in subhepatic region or undescended cecum is a rare congenital anomaly of mid gut. Usually, it remains asymptomatic and is diagnosed incidentally. If any pathology occurs in anomalous part, like appendicitis then the diagnosis and treatment will be challenging in all age groups...

Ectopic thoracic kidney is an extremely rare condition caused by the abnormal location of one or both kidneys in the thoracic cavity. They are usually discovered incidentally on routine imaging. Although commonly asymptomatic, thoracic kidneys are at a risk of malrotation, pelviureteric junction obstruction, and subsequent obstructive nephropathy, by virtue of their long pedicle. We present a case report of an incidental thoracic kidney, for which a (99m)technetium-mercaptoacetyltriglycine ((99m)Tc-MAG3) renogram was performed to assess the baseline renal function...

PURPOSE: Small bowel length is the most reliable predictor of enteral independence in pediatric short bowel syndrome. Retrospectively measured bowel lengths on upper GI with small bowel follow-through (UGI/SBFT) were compared to operative measurements. METHODS: A pediatric radiologist and surgical trainees blinded to operative measurements retrospectively analyzed UGI/SBFT studies using the digital radiography curved measurement tool. Children with SBS and severe intestinal failure (parenteral nutrition >90days) at a multidisciplinary intestinal failure program 2002-2015 were included...

OBJECTIVES: To describe the frictional forces (FF) that constrain wire sliding in the initial alignment phase of treatment using a new term, the "constraining force" (CF), and to hypothesize that CF is dependent on two factors: the hyperelastic behavior of archwires and the specific type of tooth geometric malalignment present. MATERIALS AND METHODS: A laboratory device that simulates the four distinct malalignment types (in-out, rotation, tipping, and vertical step) was used to couple with an Instron testing apparatus...

BACKGROUND: The association of neonatal intestinal obstruction with situs inversus totalis is extremely rare with only few cases reported in the literature to date. This association poses dilemmas in management. We present two such cases (of Indian origin), and briefly discuss the pertinent literature and measures to prevent unfavorable outcome. CASE PRESENTATION: Case 1: a 1-month-old preterm (1300 g) male neonate belonging to Hindu (Indian) ethnicity presented with recurrent bile-stained vomiting, non-passage of stools and epigastric fullness...

We report the case of a malrotated right kidney associated with giant prenatal hydronephrosis due to a non vascular extrinsic ureteropelvic compression. The kidney presented an hyper-rotation of 180° in relation to the original fetal position, with the renal hilum backward looking. At neonatal surgery we discover that the inferior pole of the kidney pushes laterally the ureteropelvic junction like a violin bridge. The simple uncrossing of the ureteropelvic junction from the inferior renal pole relieves the extrinsic ureteral obstacle and the giant hydronephrosis...

BACKGROUND: Advances in diagnostic techniques and perioperative care have greatly improved the outcome of neonatal surgery. Despite this, disparity still exists in the outcome of neonatal surgery between developed and developing countries. METHOD: We performed a prospective study of neonates admitted and treated due to surgical congenital diseases and other conditions in our hospital from April 2015 to April 2017. RESULTS: There were 19 (28,7%) females and 47 (70,3%) males in this group...

Over the years, the aVR lead has been overlooked by clinicians while observing a normal 12-lead ECG (electrocardiogram). A positive P-QRS complex in the aVR lead should raise prompt suspicion for either a congenital heart malrotation or a lead misplacement. In this article we present a case of an asymptomatic patient and a pathological ECG strip displaying ST elevations and a positive QRS in the aVR lead. A follow-up ECG was performed in the emergency department, and revealed a normal sinus rhythm with no abnormalities indicating acute ischemia...

Immediate breast reconstruction is an acceptable treatment option after mastectomy for prophylaxis of early breast cancer. Different options exist for implant placement, incision technique, patient suitability, and institutional experience. This article is a case series exploring the feasibility and outcomes of patients undergoing immediate breast reconstruction using skin-sparing mastectomy without mesh or acellular dermal matrix (ADM) and with a vertical inframammary incision. METHODS: A single-institution retrospective analysis was performed for all patients who underwent immediate single-stage reconstruction with subcutaneous silicon implants without ADM between 2009 and 2014 inclusive...

Intestinal malrotation occurs if midgut does not complete or partially completes its 270° counter-clockwise rotation around the superior mesenteric artery during embryologic life. In general, it frequently manifests with vomiting due to duodenal obstruction and volvulus in the initial months of life, and it is very rare to manifest in the adulthood. A 20-year-old male patient who had severe abdominal pain, nausea, vomiting, and distention for one day was evaluated at the emergency department. On abdominal tomography "swirling appearance of structures around the superior mesenteric artery" was reported...
