II. OVERVIEW By definition, PBI violates the subarachnoid space and creates a potential CSF leak. In addition to leakage from entry or exit sites, a fistula may occur at a remote site because of skull fracture and a dural tear from a blowout mechanism. High-velocity missiles may create transients of extremely high intracranial pressure, which can produce fractures even in the base of the skull....

Trapdoor fractures, or blowout fractures, result from muscle entrapment after orbital floor fractures. The incarcerated muscles may become necrotic because of ischemia; immediate surgery is recommended for symptomatic persistent diplopia or clinical evidence of entrapment. We report a case of spontaneous resolution of diplopia in a patient with a high suspicion of a trapdoor fracture. A 15-year...

PURPOSE To measure the femoral tunnel length created through a far medial portal and determine its correlation with body height, limb length, and thigh length in 404 Indian patients undergoing anterior cruciate ligament (ACL) reconstruction. METHODS 364 male and 40 female Indian patients aged 18 to 51 (mean, 26.8) years underwent ACL reconstruction by a single surgeon using the hamstrings ten...

Suppose a chaotic attractor A in an invariant subspace loses stability on varying a parameter At the point of loss of stability the most positive Lya punov exponent of the natural measure on A crosses zero at what has been called a blowout bifurcation We introduce the notion of an essential basin of an attractor with an invari ant measure This is the set of points such that the set of measures ...

In this paper, a novel approach of developing the Bayesian network for fault diagnosis based on operation procedures is presented. The proposed Bayesian network consists of operation procedure layer, fault layer and fault symptom layer. First, operation procedure layer containing procedure nodes and state decision nodes is developed. Second, the fault layer is determined based on the state deci...

Blowout fracture with entrapped orbital contents within the maxillary sinus is common due to fragility of inferior wall, but complete herniation eye globe extremely rare and emergent. Dealing such a case appears be real challenge for any ophthalmologist. We herein present 31-year-old woman entire eyeball missing from orbit following road traffic accident. Imaging revealed into sinus. The patien...

We examine global dynamics and bifurcations occurring in a truncated model of a stellar mean-field dynamo. This model has symmetry-forced invariant subspaces for the dynamics and we find examples of transient type I intermittency and blowout bifurcations to transient on-off intermittency, involving laminar phases in the invariant submanifold. In particular, our model provides examples of blowou...
