Open Reduction Internal fixation of Incarcerated Greater Tuberosity Avulsion Fracture: A Case Report.

Introduction: Proximal humerus fractures are common injuries of the upper extremity. These fractures are frequent in the elderly population due to low-energy trauma and in the younger patient secondary to high-energy trauma that is associated with shoulder dislocations. Proximal humerus fractures are frequently classified according to the Neer classification which is defined by the number of segments and the amount displacement required to define the fracture as displaced.

A Technique for Anterior Cruciate Ligament Reconstruction in the Setting of Unicompartmental Knee Arthroplasty.

Unicompartmental knee arthroplasty (UKA) is becoming a more prevalent treatment for medial-compartment arthritis. Traditionally, a competent anterior cruciate ligament (ACL) is required to achieve satisfactory results. This leads to the question of treatment for medial-compartment arthritis in the setting of an incompetent ACL.

The role of the dorsal dentate gyrus in object and object-context recognition.

The aim of this study was to determine the role of the dorsal dentate gyrus (dDG) in object recognition memory using a black box and object-context recognition memory using a clear box with available cues that define a spatial context. Based on a 10 min retention interval between the study phase and the test phase, the results indicated that dDG lesioned rats are impaired when compared to controls in the object-context recognition test in the clear box. However, there were no reliable differences between the dDG lesioned rats and the control group for the object recognition test in the black box.
