PURPOSE AND HYPOTHESIS: Correct femoral component rotation at knee arthroplasty influences patellar tracking and may determine function at extremes of movement. Additionally, such malrotation may deleteriously influence flexion/extension gap geometry and soft tissue balancing kinematics. Little is known about the effect of subtle rotational change upon load transfer across the tibiofemoral articulation. Our null hypothesis was that femoral component rotation would not influence load across this joint in predictable manner...

Heterotaxy syndrome (HS) is a congenital disorder resulting from an abnormal arrangement of visceral organs across the normal left-right axis in the embryonic period. HS is usually associated with multiple anomalies, including defects of the major cardiovascular system and the extracardiovascular system such as intestinal malrotation, abnormal lung lobulation, bronchus anomalies, and pancreatic dysplasia. Although pancreatic dysplasia is occasionally accompanied with HS, the occurrence of diabetes mellitus (DM) due to pancreatic dysplasia in HS is rarely reported...

Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) is a rare disease of functional obstruction affecting the bladder and intestines, characterized by a markedly distended bladder, microcolon, and decreased or absent intestinal peristalsis. Afflicted neonates have very poor prognosis, usually with fatal outcomes in first days to months of life. Placental fetal thrombotic vasculopathy (FTV) is a thrombo-occlusive disorder of the chorionic plate and fetal circulation. Herein, we describe an undocumented association of MMIHS and placental FTV...

BACKGROUND: The purpose of this study was to determine whether placing the suture-button device between the long and small finger metacarpals following ring finger ray amputation may better close the intermetacarpal gap and allow early range of motion without increasing the risk of malrotation than soft tissue repair alone. METHODS: We performed ray amputation of the ring finger of 14 cadaver specimens by performing an osteotomy of the base of the ring finger metacarpal and then excising the remainder of the digit...

OBJECTIVE: The cause of the chylous ascites in infants isn't completely clear. The purpose of this study is to discuss our experience of recognition of intestinal malrotation as a cause of congenital chylous ascites in infants. METHODS: Medical information of 10 infants with chylous ascites, who were admitted to the hospital between 2001 and 2014, was retrospective analyzed. Preoperatively, all patients underwent a period of conservative treatment. RESULTS: We found that nine of ten patients with intestinal malrotation, six of them underwent laparoscopic Ladd's procedure and three patients underwent open Ladd's procedure...

INTRODUCTION: Various reconstructions of the gastro-intestinal tract have been described in the past after distal gastrectomy. Among these, a Billroth II (BII) anastomosis can be performed with the addition of the Omega entero-enterostomy that may theoretically reduce the alkaline reflux. Given the significant complications associated with this procedure such as biliary reflux, marginal ulceration, and afferent loop syndrome, a revision into a Roux-en-Y anatomy is generally recommended...

BACKGROUND: Anatomical imaging findings indicating normal bowel rotation can be identified on cross-sectional imaging, including magnetic resonance imaging (MRI) performed for non-related indications. OBJECTIVE: The goal of our study was to assess whether non-targeted MRI can accurately assess intestinal malrotation. MATERIALS AND METHODS: Four anatomical landmarks were assessed on MRIs of the chest, spine or abdomen performed from January 2006 to June 2014, on patients who also had upper gastrointestinal series (UGI) performed within 10 years of the MRI date: 1) retroperitoneal duodenum, 2) left upper quadrant duodenojejunal junction, 3) superior mesenteric artery to the left of the superior mesenteric vein, and 4) right lower quadrant cecum...

Hand fractures are among the most common skeletal injuries. Approximately 150,000 hand fractures occur in the United States each year. The management of hand fractures consists of reduction, immobilization, and rehabilitation to return patients to their preinjury status. Hand fractures are managed by restoring articular congruity, reducing malrotation and angulation of the fracture, and maintaining the reduction, all of which should be accomplished with minimal surgical intervention. Surgeons must assess concomitant soft-tissue injuries and respect the soft tissues during the surgical management of hand fractures...

BACKGROUND: The most common modes of failure for megaprostheses are aseptic loosening followed by periprosthetic infection and stem fracture. Surgical technique for bone and implant exposure is controversial and may influence the success of revision and the need for additional future revisions. The purpose of this study was to evaluate the effectiveness of cortical fenestration for megaprosthesis revision, particularly for stem fracture. METHODS: From 1985-2014, 196 adult and pediatric patients underwent limb salvage with a distal femoral or proximal tibial megaprosthesis (109 cemented, 87 pressfit)...

We report a case of a 53-year-old male who presented with acute onset right upper quadrant (RUQ) abdominal pain with investigations demonstrating malrotation causing midgut volvulus and subsequent intestinal obstruction. The patient was consented for an emergent operation and underwent an exploratory laparotomy. Operative findings included the presence of adhesive bands in the RUQ (Ladd's Band), volvulus of the mid-portion of the small bowel in a clockwise fashion and multiple intra-abdominal adhesions causing internal hernias...

INTRODUCTION: Volvulus may be noted in up to two-thirds of cases involving malrotation beyond infancy. Laparoscopic devolvulation has been described as a frustrating procedure because of restricted visualization. Here, a setup and technique that address these concerns are proposed. MATERIALS AND SURGICAL TECHNIQUE: Three boys (median age: 7 years) who had been diagnosed preoperatively with malrotation underwent laparoscopic exploration and devolvulation for volvulus found intraoperatively...

PURPOSE: The gold standard for the diagnosis of malrotation is barium contrast study of the upper gastrointestinal system (UGCS), while color Doppler ultrasonography (CDUS) is another method used in the diagnosis. We investigated the value of CDUS for the diagnosis of malrotation in this study. METHODS: UGCS images, CDUS images, plain abdominal images, demographic data, and symptoms of 82 patients who were investigated for presumed malrotation during a 7-year period were evaluated, retrospectively...

Lymphedema distichiasis syndrome (LDS) is a rare, autosomal dominant genetic condition, characterized by lower limb lymphedema and distichiasis. Other associated features that have been reported include varicose veins, cleft palate, congenital heart defects, and ptosis. We update a previously reported family with a pathogenic variant in FOXC2 (c.412-413insT) where five affected individuals from the youngest generation had congenital renal anomalies detected on prenatal ultrasound scan. These included four fetuses with hydronephrosis and one with bilateral renal agenesis...

Interlocked intramedullary nailing is the treatment of choice for femoral shaft fractures. However, distal locking is a technically challenging part of the procedure that can result in distal femoral malrotation and high radiation exposure. We have tested a robotic procedure for robotic distal locking based on the computation of a drilling trajectory on two calibrated fluoroscopic images. Twenty distal holes were attempted in ten cadaveric femur specimens. Successful screw hole drilling was achieved at the first attempt in each of the ten specimens (20 drill holes in total)...

Malunion at the shaft of the middle phalanx yields less functional problems compared with malunion at the shaft of the proximal phalanx and metacarpal bones. In the present report, the patient sustained a minimally displaced fracture at the distal portion of the distal middle phalanx of the ring finger spraining the finger during playing flag football. Fracture was treated conservatively and fracture union was completed. However, the patient complained of functional problems in activities of daily living due to the malrotational deformity of the finger...
