BACKGROUND Posterolateral rotatory instability is a type of ulnohumeral instability seen following elbow trauma. It is caused by a deficiency in the lateral collateral ligament complex that allows the radius and ulna to subluxate as a single unit with respect to the distal part of the humerus. There are few studies on this type of instability in children. Our purpose was to evaluate cases of po...

BACKGROUND Objective measures to quantitate the amount of lateral compartment opening for patients with lateral and posterolateral knee injuries have not been well documented. The purpose of the present study was to measure lateral compartment opening secondary to applied varus stresses following posterolateral corner structure sectioning and to develop radiographic guidelines to quantify the a...

The authors describe an arthroscopic surgical technique for posterior capsulolabral repair using standard portals while patients are in the beach-chair position. The technique is unique in that the suture anchors are inserted from a superior-to-inferior direction instead of the traditional posterolateral-to-anteromedial direction. It involves the use of a posterolateral or mid-lateral portal th...

With the advent of the relatively safe water-soluble contrast medium metrizamide, cervical myelography followed by metrizamide computed tomography (CT) can be performed easily. Sixteen patients with cervical disk protrusions (eight central and eight posterolateral) were studied by both procedures to evaluate the diagnostic value of each. In 75% of the posterolateral disk protrusions, myelograph...

OBJECTIVE To describe patient selection criteria, surgical technique and early outcomes in patients undergoing reoperative coronary artery bypass surgery (RECABG) through a left thoracotomy without cardiopulmonary bypass (CPB). METHODS Eight patients with patent grafts to the anterior interventricular branch of left coronary artery (four of which had also patent grafts to the right coronary a...

To explore the role of oscillatory dynamics of the somatosensory thalamocortical network in perception and decision making, we recorded the simultaneous neuronal activity in the ventral posterolateral nucleus (VPL) of the somatosensory thalamus and primary somatosensory cortex (S1) in two macaque monkeys performing a vibrotactile detection task. Actively detecting a vibrotactile stimulus and re...

RSM is a powerful tool for optimizing photocatalytic processes. The BWO-GO photocatalysts have been successfully synthesized via inorganic-salt-assisted hydrothermal method. XRD, TEM, FESEM, HRTEM and STEM are used to characterize BWO-GO heterojunction. UV-vis, PL, ESR and radical scavenger experiments are used to explore the photocatalysis mechanism. The photocatalysts are evaluated by TC phot...

Abstract Morphological diversity of sound-producing structures has not been well investigated among members superorder Peracarida. Presumptive stridulatory organs have reported in some amphipods and tanaidaceans, sound production by these documented two isopod species Oniscidea Sphaeromatidea. We describe three presumptive the paranthurid Paranthura cf. japonica Richardson, 1909, first case kno...
