isolated scaphoid dislocation is a rare injury of the wrist. to our knowledger, only 22 cases of isolated scaphoid dislocation have been reported in enghish-language literature and we could find only one case with pure radial dislocation. we present a 34-year-old man with isolated pure radial scaphoid dislocation that was treated by open reduction and repair of the scapholunate ligament and pin...

PURPOSE To compare 5 different Kirschner wire fixation techniques in terms of the failure loads seen as scapholunate (SL) dissociation in a cadaveric, biomechanical study. METHODS 10 fresh-frozen, finger-amputated wrists with sectioned SL ligaments from 3 male and 2 female cadavers were tested. The change of SL angle, SL dissociation, and the load to failure of the 5 different Kirschner wire ...

Excision of the proximal carpal row has proven over the past 60 years to be an effective technique for certain disorders of the wrist, including degenerative sequelae of scapholunate ligament dissociation and scaphoid nonunions, Kienböck disease, Preisser disease, and other fracture-dislocations of the wrist. The durability of this procedure may be due to remodeling of the capitate head to the ...

We present a novel framework for inferring 3D carpal bone kinematics and bone shapes from a single view fluoroscopic sequence. A hybrid statistical model representing both the kinematics and shape variation of the carpal bones is built, based on a number of 3D CT data sets obtained from different subjects at different poses. Given a fluoroscopic sequence, the wrist pose, carpal bone kinematics ...

Four corner arthrodesis is an accepted salvage operation for scapholunate advanced collapse and scaphoid non-union advanced collapse. Circular plates were introduced in 1999 and promoted as a rapid and more stable method for this procedure. A retrospective chart review was performed on all patients who were treated with the Spider Limited Wrist Fusion Plate (Kinetikos Medical Inc., San Diego, C...
