This study is a retrospective review of 122 patients who underwent single-level lumbar spine fusion. The objectives were to directly compare perioperative morbidity and early results of single-level anterior interbody posterolateral intertransverse process lumbar spine fusion and to provide objective findings that may be useful in selecting surgical method. Lumbar spinal fusion is a well-recogn...

Spinal intradural extramedullary schwannomas commonly occur posterolateral or anterolateral to the spinal cord. A case of a pure midline ventrally situated cervicodorsal extramedullary schwannoma in a 33-year-old female patient with subacute cord compression and sphincteric involvement is presented. Spinal MR imaging showed a C2-D3 midline ventrally situated extramedullary tumor with severe spi...

posterior malleolar fracture is a displaced fragment that involves more than 25%–35% of the articular surface of the distal tibia. A number of different surgical approaches to this fracture have been advocated. Often, the posterior fragment reduces simultaneously when the lateral malleolus is reduced because of their respective attachments to the posteroinferior tibiofibular ligament (PITFL). T...

injuries to the posterolateral corner (plc) comprise a significant portion of knee ligament injuries. a high index of suspicion is necessary when evaluating the injured knee to detect these sometimes occult injuries. moreover, a thorough physical examination and a comprehensive review of radiographic studies are necessary to identify these injuries. in this sense, stress radiographs can help to...

OBJECTIVE Evaluate the correlation between magnetic resonance imaging, clinical examination and intraoperative identification of posterolateral corner injuries of the knee. METHODS We compared the findings of physical examination under anesthesia and intraoperative findings as the gold standard for the posterolateral corner injury with the reports of the MRIs of patients who underwent reconst...

INTRODUCTION Autogenous iliac crest bone graft continues to be the material of choice for posterolateral lumbar intertransverse process spine fusion. However, continued interest lies in developing bone graft alternatives that can be used as either graft extenders, graft enhancers, or graft substitutes. It was the purpose of this study to evaluate the efficacy of a demineralized bone matrix/ hya...

To determine how often acute lateral myocardial infarcts may be electrocardiographically "silent," a new approach was utilized in which subjects were selected by admission thallium scintigraphy. Thirty-one patients with their first infarction were identified with moderate to severe perfusion defects of the lateral and posterolateral walls, persistent over 7 days and associated with severe wall ...

OBJECTIVE Posterior fossa hemorrhages may be underdiagnosed in surviving neonates, with cerebellar hemorrhage discovered in 10% to 25% of autopsy specimens from very low birth weight infants. Posterior fossa lesions have been difficult to visualize by the traditional ultrasonography approach through the anterior fontanelle. Late in 1994, routine posterior fossa imaging through the posterolatera...

BACKGROUND There is controversy regarding the necessity of reconstructing both the posterolateral and anteromedial bundles of the anterior cruciate ligament. HYPOTHESIS A laterally oriented transtibial drilled femoral tunnel replaces portions of the femoral footprints of the anteromedial and posterolateral bundles of the anterior cruciate ligament. STUDY DESIGN Descriptive laboratory study....

An anatomical study was conducted to gain orientation regarding the posterolateral approaches. The asterion is defined as the junction of the lambdoid, parietomastoid, and occipitomastoid sutures. This anatomical point has been widely used as a landmark in lateral approaches to posterior fossa. Although there are many common practices in posterolateral approaches, studies providing accurate ana...
