Isolated dislocation of the carpal scaphoid is a rare injury. Such dislocation is extremely rare. In this article the authors report a twenty-eight-year-old man with isolated dislocation of the scaphoid with associating radial styloid fracture. We manage the patient with open reduction and Kirschner wire fixation. One year later there is a good functional and radiographic result.

The cause of dislocation of an intraocular lens is a direct blow or jerk, and dislocation may complicate both iris-supported and capsule-supported lenses. In capsule-supported lenses the implant dislocates towards the anterior chamber but in iris-supported lenses the dislocation is posterior. A technique for removal of a posterity dislocated lens is described.

  Background : Glenoid bone damages consisting of anterior rim erosion and bony avulsion are very important in decision making for treatment of recurrent dislocation in shoulder joint. This study was aimed to determine the prevalence of these damages in patients with anterior recurrent shoulder dislocation.   Methods : The study was a cross-sectional study evaluating patients with unstable shou...

Background: To facilitate shoulder reduction and shorten time from shoulder dislocation to reduction, we started in 2014 a protocol for ultrasound-guided interscalene block (UGIB) in pure shoulder dislocation as well as dislocation with greater tuberosity fracture and dislocated shoulder arthroplasty. Methods: Within 30 month, patients with shoulder dislocation, dislocation-fracture or dislocat...

A 35 year old man presented to our emergency department after a traffic injury. Radiographic evaluation showed plantar dislocation of the second metatarsophalangeal joint and dorsal dislocation at the second tarsometatarsal joint. Under general anesthesia, closed reduction of the metatarsophalangeal joint was performed, followed by percutaneous fixation with a Kirschner-wire, and immobilization...

We report experimental and three-dimensional discrete dislocation dynamics measurements to characterize the effect of high starting dislocation density on size-affected flow. Microcrystals were focused ion beam milled into a pre-strained bulk Ni single crystal to obtain a dense heterogeneous dislocation cell structure. The strength-scaling exponent is shown to decreases considerably with increa...

A review of 35 cases of acute injury of the upper thoracic spine associated with paraplegia was done. In 32, a fracture-dislocation was present; in two, there was a dislocation without associated fracture; and in one, neither fracture nor dislocation was identified. A total of 22 cases conformed to a pattern of injury consisting of anterior fracture dislocation with disruption of the intervenin...

We present a sorting algorithm for the case of recurrent random comparison errors. The algorithm essentially achieves simultaneously good properties of previous algorithms for sorting n distinct elements in this model. In particular, it runs in O(n2) time, the maximum dislocation of the elements in the output is O(logn), while the total dislocation is O(n). These guarantees are the best possibl...

The post-traumatic dislocation of the fifth-finger is a rare lesion. In the absence of treatment, this lesion results in joint degeneration and instability. This lesion is usually unstable, treated by open, Closed. We report the case of a carpal-metacarpal dislocation isolated palmar pure in a boxer, clinically the patient presented a disturbance of rotation of 15° with a shortening of 5 mm. Th...
