PURPOSE: It was hypothesized that malrotation of femoral component in total knee arthroplasty (TKA) will significantly impact clinical outcome. METHODS: Eighty-eight consecutive patients with primary osteoarthritis of the knee were prospectively evaluated. They received a cemented posterior stabilized TKA (NexGen, Zimmer/Biomet® Inc., Warsaw, IN, USA). The femoral component was placed in 3° of external rotation referenced to the posterior condylar line. Postoperatively, a CT scan was performed to evaluate rotation of femoral component in the transverse plane...

Malrotation of the gut is a common paediatric condition that usually presents in the first month of life. However, presentation in adults is rare, and as a diagnostic dilemma quite often surprises the surgeon intraoperatively. If this condition is not timely recognized, it may result in disastrous consequences, such as gangrene of the small gut. We present the case of a 21-year-old male who presented to the emergency room with recurrent episodes of colicky abdominal pain and bilious vomiting. Contrast-enhanced computerized tomography (CT) revealed malrotation of the gut...

BACKGROUND: "Grand-piano sign" has been used as a popular benchmark to facilitate correct rotational alignment during total knee arthroplasty (TKA). The purpose was to quantitatively determine morphological patterns on anterior femoral resection in mechanically aligned (MA) and kinematically aligned (KA) TKA. METHODS: Computed tomography scans of 60 TKA candidates were reconstructed into 3D models. Femurs were virtually cut with a 3D imaging program using various anterior flange flexion angles (AFFAs) of 3°, 5°, and 7°...

Introduction: Since the first description by William Ladd, the Ladd's procedure has been the surgery of choice for the correction of malrotation. The laparoscopic Ladd's procedure is becoming popular with the advent of minimal access surgery and is described in the literature. Various techniques of the Ladd's procedure have been described but none of them describes the stepwise technique for derotation of volvulus which is the most difficult and confusing part of the surgery. We describe 'steering wheel' technique for easy derotation of volvulus associated with malrotation...

The Wilms tumor suppressor gene (Wt1) encodes a transcription factor involved in the development of a number of organs, but the role played by Wt1 in pancreatic development is unknown. The pancreas contains a population of pancreatic stellate cells (PSC) very important for pancreatic physiology. We described elsewhere that hepatic stellate cells originate from the WT1-expressing liver mesothelium. Thus, we checked if the origin of PSCs was similar. WT1 is expressed in the pancreatic mesothelium. Between E10...

We report a novel patient with the phenotypic characteristics of Schaaf-Yang syndrome. In addition, the patient has a severe chronic digestive malfunction, rendering him dependent on intermittent enteral supplementation. To our knowledge, this is the first report of Schaaf-Yang syndrome associated with severe chronic digestive malfunction manifesting with both a malrotation and signs of a chronic intestinal pseudo-obstruction.

BACKGROUND Appendicitis is the most common cause of abdominal pain requiring emergent surgical intervention. Although typically presenting as right lower-quadrant pain, in rare cases it may present as left upper-quadrant pain secondary to abnormal position due to intestinal malrotation. Since atypical presentations may result in diagnostic and management delay, increasing morbidity and mortality, accurate and prompt diagnosis is important. Therefore, acute appendicitis should be considered in the differential diagnosis of left upper-quadrant abdominal pain...

INTRODUCTION: Gallbladder torsion is a rare condition of increasing prevalence in recent years. It is often difficult to diagnose pre-operatively and delayed intervention can lead to significant complications. PRESENTATION OF CASE: We present a case of an 81 year old lady who presented with symptoms of cholecystitis for 24 h with no evidence of cholelithiasis on imaging. She deteriorated within 24 h of admission despite intravenous antibiotics; Emergency laparoscopy was performed which showed the gallbladder malrotated 180 ° with features of necrosis...

Malrotation of the midgut is generally considered as a pediatric pathology with the majority of patients presenting in childhood. The diagnosis is rare in adults, which sometimes leads to delay in diagnosis and treatment. An index of suspicion is therefore required when dealing with patients of any age group with abdominal symptoms. We present a case of a 26-year-old male who presented with left lower abdominal pain with preoperative computed tomography showing suspected left-sided appendicitis associated with midgut malrotation...

BACKGROUND: Correct positioning of the cup is an important factor in total hip arthroplasty. Assessing its position from a plain anteroposterior pelvic radiograph is known to be hampered by systemic errors. This study focuses on developing a correction method to adjust for these potential sources of error and to eliminate them based on a 3D geometric analysis. METHODS: Computed tomography scans of 113 (66 male, 47 female) pelvices were reconstructed and virtually projected onto a plain radiograph with varying rotational and translational positions...

We present a case of 14-year girl with left-sided acute appendicitis who presented with lower abdominal pain. Midgut malrotation occurs at a rate of 1 in 500 live births. The condition is incidentally diagnosed during various radiological investigations done for other purposes. However, such patients may present with conditions like acute appendicitis, which poses a diagnostic dilemma if a high index of suspicion is not kept. The purpose of this case report is to increase awareness in the emergency physicians and young surgeons of this rare presentation; and the importance of radiological investigations in the diagnosis of left-sided appendicitis, to decrease morbidity and mortality...

INTRODUCTION: Isomerism, or heterotaxy syndrome, affects many organ systems anatomically and functionally. Intestinal malrotation is common in patients with isomerism. Despite a low reported risk of volvulus, some physicians perform routine screening and prophylactic Ladd procedures on asymptomatic patients with isomerism who are found to have intestinal malrotation. The primary aim of this study was to determine if isomerism is an independent risk factor for volvulus. METHODS: Kid's Inpatient Database data from 1997 to 2012 was utilized for this study...

Acute appendicitis is the most common cause of acute abdominal pain, requiring emergency surgery. Approximately one third of cases have pain unexcepted location due to its various anatomical location. Acute appendicitis is a very rare cause of left lower quadrant pain; if it occurs, a few congenital anomalies should be considered such as Situs Inversus totalis and Midgut Malrotation (MM). MM is a rare congenital anomaly; it occurs due to error in process of rotation or fixation of intestines around the superior mesenteric vessels and it refers to nonrotation or incomplete rotation of intestines...

We present a case of pyeloduodenal fistula in an 89-year-old woman with history of nephrolithiasis and recurrent urinary tract infection (UTI) who presented to the emergency department with back pain. CT revealed a malrotated right kidney with a large renal stone and possible fistulous connection between the second portion of the duodenum and the right renal collecting system. Technetium-99m scintigraphy confirmed presence of the fistula. The patient declined intervention and was discharged from the hospital with oral antibiotic suppressive therapy...

BACKGROUND: Malrotation of tibial and femoral components is a potential source of pain following total knee arthroplasty (TKA). This study aimed to 1) compare component rotation in TKA patients with unexplained pain versus a control group with well-functioning TKAs and 2) investigate the relationship between TKA component rotation and pain. METHODS: Seventy one patients with unexplained pain after primary TKA were compared to a control cohort of 41 well functioning TKA patients...

Anilawan Smitthimedhin, Angela Suarez, Ryan L Webb, Hansel J Otero
Intestinal malrotation is a continuum of congenital anomalies due to lack of rotation or incomplete rotation of the fetal intestine around the superior mesenteric artery axis. The abnormal bowel fixation (by mesenteric bands) or absence of fixation of portions of the bowel increases the risk of bowel obstruction, acute or chronic volvulus, and bowel necrosis. The clinical presentation of patients with malrotation without, with intermittent, or with chronic volvulus can be problematic, with an important minority presenting late or having atypical or chronic symptoms, such as intermittent vomiting, abdominal pain, duodenal obstruction, or failure to thrive...

Lucas S Marchand, Dane C Todd, Patrick Kellam, Temitope F Adeyemi, David L Rothberg, Travis G Maak
BACKGROUND: Restoring normal femoral rotation is an important consideration when managing femur fractures. Femoral malrotation after fixation is common and several preventive techniques have been described. Use of the lesser trochanter profile is a simple method to prevent malrotation, because the profile changes with femoral rotation, but the accuracy of this method is unclear. QUESTIONS/PURPOSES: The purposes of this study were (1) to report the rotational profiles of uninjured femora in an adult population; and (2) to determine if the lesser trochanter profile was associated with variability in femoral rotation...
