OBJECTIVE To determine the prevalence of heterotopic bone formation in cemented versus noncemented total hip joint replacement. DESIGN A prospective randomized controlled trial. Follow-up ranged from 2 to 6 years (mean 4 years). SETTING A university hospital. PATIENTS Two hundred and twenty-six patients who had primary or secondary osteoarthrosis of the hip were stratified according to ty...

BACKGROUND Heterotopic ossification is a common postoperative complication of acetabular fracture. However, functionally significant heterotopic ossification with associated late bone defects in the posterior wall of the acetabulum is rare and challenging to treat. When heterotopic ossification is a late complication of failed acetabular fracture operation, it is disabling and may only be treat...

Heterotopic brain outside the cranial vault is uncommon. It occurs most frequently in the nasal region, although rests elsewhere in the aerodigestive tract have been reported. We describe a case of heterotopic brain in the pterygopalatine fossa.

Heterotopic pregnancy once considered a rare phenomenon is now thought to be more common as the overall incidence of ectopic continues increase. We report series six cases heterotopic pregnancies seen in our department over period seven years. Two these occurred after assisted reproductive techniques; while other were spontaneous pregnancies. The clinical presentation was varied with late diagn...

We describe the case of a 37-year-old woman who had undergone reversal of tubal ligation with subsequent heterotopic pregnancy. We review the initial radiological evaluation of heterotopic pregnancies and the subsequent radiologic findings following appropriate therapy.

Ipsilateral displaced acetabular and femoral shaft fractures represent a dilemma for orthopedic surgeons because antegrade femoral nailing may complicate a Kocher-Langenbeck acetabular exposure. The goals of this study were to review the results of ipsilateral femoral and acetabular fractures treated with antegrade femoral nailing and a Kocher-Langenbeck approach and to evaluate the assertion t...

CONTEXT Heterotopic pancreatic tissue is defined as pancreatic tissue outside the boundaries of the pancreas that has neither anatomic nor vascular continuity with the pancreas. Heterotopic pancreatic tissue in the gallbladder is uncommon and has rarely been reported to cause symptoms. We report a case of heterotopic pancreatic tissue obstructing the gallbladder neck resulting in cholecystitis....

BACKGROUND Perivascular epithelioid-cell tumor (PEComa) is a group of rare mesenchymal neoplasms that express myomelanocytic-cell markers and exhibit a wide variety of histopathological features. Although heterotopic pancreas has been reported to occur in the gastrointestinal tract, intrahepatic heterotopic pancreas has been reported only rarely. CASE PRESENTATION We present a case of intrahe...

Cortical malformations are often associated with refractory epilepsy and cognitive deficit. Clinical and experimental studies have demonstrated an important role for glutamate-mediated synaptic transmission in these conditions. Using whole cell voltage-clamp techniques, we examined evoked glutamate-mediated excitatory postsynaptic currents (eEPSCs) and responses to exogenously applied glutamate...

Heterotopic pancreas is defined as arising of pancreatic tissue ectopically with no anatomical, neural or vascular connection to the normal pancreas [1]. We present here an unusual case that has two heterotopic pancreatic tissues in antrum. A 31-year-old woman was admitted to our outpatient clinic with a four-month history of epigastric pain and dyspepsia. All laboratory tests of the patient we...
