There are marked individual differences in the recollection of personal past events or autobiographical memory (AM). Theory concerning the relationship between mnemonic and visual systems suggests that eye movements promote retrieval of spatiotemporal details from memory, yet assessment of this prediction within naturalistic AM has been limited. We examined the relationship of eye movements to free recall of naturalistic AM and how this relationship is modulated by individual differences in AM capacity. Participants freely recalled past episodes while viewing a blank screen under free and fixed viewing conditions...

The spine is a frequent site of cancer metastasis leading to intractable pain, functional impairment, and poor quality of life. When analgesic regimens and nonpharmacological interventions fail, spine surgery may be indicated. For patients with advanced disease, the decision to operate can become a dilemma. A patient with colon cancer metastatic to his spine, who had undergone multiple procedures for back pain, was admitted to a palliative care unit, where pain persisted despite high-dose opioids and adjuvant analgesics...

Six degrees of freedom (6DOF) refers to the freedom of movement of a rigid body in 3-dimensional space. Specifically, the object can move in 3 translations: up/down, left/right, and in/out, and in 3 rotations: pitch, yaw, and roll. In fracture care, the principle of 6DOF can be applied to each individual fracture fragment to help better understand fracture reduction and alignment. In the instance of a distal radius fracture, the 6DOF concept can be utilized to reduce the articular block in a systematic and controlled fashion...

One component of vestibular rehabilitation in patients with vestibulo-ocular reflex (VOR) hypofunction is gaze-stabilizing exercises that seek to increase (adapt) the VOR response. These prescribed home-based exercises are performed by the patient and thus their use/training is inherently variable. We sought to determine whether this variability affected VOR adaptation in ten healthy controls (× 2 training only) and ten patients with unilateral vestibular hypofunction (× 1 and × 2 training). During × 1 training, patients actively (self-generated, predictable) move their head sinusoidally while viewing a stationary fixation target; for × 2 training, they moved their outstretched hand anti-phase with their head rotation while attempting to view a handheld target...

INTRODUCTION: Traditional Kirschner wire (K-wire) stabilization of first metatarsal distal chevron osteotomy involves 1 cortex of fixation; however, unicortical fixation is associated with a high complication rate, including pin migration. A method of K-wire fixation utilizing 3 cortices may be biomechanically superior and potentially equivalent to single-screw fixation. METHODS: Cadaveric specimens fixed with tricortical K-wires were tested in both the physiologic and cantilever conditions against specimens fixed with unicortical K-wires (N = 8) and single screws (N = 9) utilizing matched-pair comparison groups...

This article illustrates a new technique for repositioning the lip in the treatment of gummy smile. In particular, it introduces a formula to precisely calculate how much tissue should be eliminated to avoid the recurrence of gummy smile. The modified lip-repositioning technique (MLRT) also involves the microsurgical division of the tissue components (mucosa, periosteum, and bone) as well as the fixation of the surgically modified tissue to the periosteum component. The results of the technique are shown through case presentations of seven patients with follow-up of up to 3 years...

Ideberg type III glenoid fractures are relatively rare, and the mechanisms of injury and treatment strategies remain controversial. We reviewed the fracture patterns and final radiological findings in four cases. All fractures were wider on the medial side than on the side of the articular surface. All patients had multiple ipsilateral rib fractures; three out of four patients had a concomitant acromion fracture. Therefore, the mechanism of injury for the fracture is assumed to be external force applied in the caudal direction to the medial side of the body of the scapula...
