The different prefrontal cortical regions exert executive control over processing occurring in posterior cortical regions. We examined with the autoradiographic method, in the macaque monkey, the course and terminations of the efferent corticocortical connections of the rostral prefrontal region, the function of which is least understood. Three efferent streams of fibers organized into three di...

OBJECTIVE To determine if diagnostic signs of adhesive capsulitis (AC) of the shoulder at Magnetic Resonance Imaging (MRI) and arthrography (MRA) are applicable to CT arthrography (CTA). METHODS 22 shoulder CTAs with AC were retrospectively reviewed for features described in MR literature. The control group was composed of 83 shoulder CTA divided into four subgroups 1) normal (N = 20), 2) oma...

OBJECTIVES To demonstrate a novel approach to cricoarytenoid joint (CAJ) injections. STUDY DESIGN Anatomic feasibility study. METHODS Five human cadaveric larynges providing 10 CAJ s were used to obtain trajectory measurements of a 27-gauge 1½-inch needle placed between the CAJ capsule and the contralateral cricothyroid membrane. Ten additional larynges providing 20 CAJ s were then used to ...

Computed tomography (CT) findings were analyzed in 17 patients with hypertensive putaminal hemorrhage accompanied by hemiplegia which had subsided almost completely by conservative therapy within one month after the onset. In such patients a high density area was not seen at the level of the lateral ventricles on CT scan. To study the reason for this, the relationship between the extent of a he...

Proximal tibiofibular subluxation is the symptomatic hypermobility of the proximal tibiofibular joint. Pain along the lateral aspect of the knee must be carefully evaluated as the anatomy and biomechanics of this region are very complex. Anatomical variants of the proximal tibiofibular joint may be key to understanding the pathomechanics and, thus, treatment of this joint. The "horizontal" prox...

Background: The anatomy of the posterolateral corner (PLC) knee is complex. approach PLC can be a challenging and stressful surgical time. Indications: indications are meniscal repair, open lateral meniscus allograft transplantation, tibial plateau fracture, reconstruction for grade III sprains. Technique Description: skin incision straight, realized with positioned at 90° flexion, passing slig...

We have demonstrated a novel Fourier-domain optical coherence tomography system and signal-processing algorithm for full-range, real-time, artifact-free quantitative imaging of the anterior chamber. Cross-sectional full-range images comprising 1024 x 800 pixels (axial x lateral) were acquired and displayed at 6.7 images/s. Volumetric data comprising 1024 x 400 x 60 pixels (axial x lateral x ele...

BACKGROUND Total knee arthroplasty (TKA) is a successful therapy for functional improvement and pain relief in advanced symptomatic degeneration of the knee joint. But it can be associated with many complications, one of which is instability. CASE PRESENTATION A 70-year-old woman was referred to our hospital because of right knee dislocation after TKA was performed on her right knee due to se...

Disruption of the major ligaments of the knee was seen in six young men, five parachutists and a house painter, after what we have termed abduction-traction injury. This unusual complaint results from the application of a sudden block to the ankle while falling head first, leading to traction and abduction of the knee. All the patients underwent operations, generally with unsatisfactory results...
