Near infrared absorption (NIR) spectra of natural morphologically cubic polycrystalline diamonds (cuboid) were obtained at room temperature, and the stretching plus bending combination band of molecular water was observed. The spectrum consisted of the main band at 5180 cm 1 due to liquid water and a shoulder at 5000 cm . The 5000 cm 1 band suggests the presence of a phase with stronger hydroge...

Optimal path planning problems for rigid and deformable (bendable) cuboid robots are considered by providing an analytic safety constraint using generalized Lp norms. For regular cuboid robots, level sets of weighted Lp norms generate implicit approximations of their surfaces. For bendable cuboid robots a weighted Lp norm in polar coordinates implicitly approximates the surface boundary through...

Aneurysmal bone cysts (ABC) are rare and they represent 1- 1.4 % of all primary bone tumors. ABC of cuboid bone are extremely rare, especially in children. Very few cases have been reported in the literature since 1967. We present a case of pathological fracture of cuboid bone due to an aneurysmal cyst in a 10-year-old girl. Surgery was performed, which included open biopsy with aspiration and ...

Introduction: Transcuneiform fracture patterns without dislocations are uncommon. In a review of the literature, numerous case reports describe cuneiform fracture-dislocations involving either the transmetatarsal or midtarsal joint complexes due to direct trauma; however, an isolated transcuneiform fracture pattern without dislocation has not been reported. Methods: We present a rare injury of ...

 Proximal humerus fractures are common, but associated injury of the axillary artery is uncommon. The majority of published blunt traumatic axillary artery injuries are associated with anterior glenohumeral dislocation; a few are associated with isolated proximal humerus fractures or fracture-dislocation. Experience within our institution demonstrates that axillary artery injury is often unreco...

Isolated posterior dislocation of the shoulder with ipsilateral humeral shaft fracture is a rare combination. Three cases of such co-existence have been reported so far. We report a fourth case and review the literature. Our aim is to highlight the importance of this rare co-existence. A high index of suspicion is necessary to diagnose posterior dislocation of the shoulder as most concentration...

Isolated dislocation of the proximal tibiofibular joint is a rare injury. We present a 23-year-old caucasian man who sustained a traumatic anterolateral dislocation of the proximal tibiofibular joint. There is no consenus on definitive management, and we review the different published treatment and rehabilitation regimens for this injury. Our patient was successfully treated by open reduction a...
