Figure 1. (a) Anteroposterior view of the right wrist demonstrating transradial styloid lunate dis-location. The lunate is seen overlapping the capitate, creating the classic " piece-of-pie " sign (white arrow). (b) Lateral view of the right wrist demonstrating lunate dislocation. The lunate is displaced and angulated out of the lunate fossa, producing the " spilt teacup " appearance (black arr...

A palmar dislocation of scaphoid and lunate is uncommon. We have found only 19 reported cases in the literature. We reported a simultaneous, divergent dislocation. The closed reduction followed by percutaneous pinning has given a good result without avascular necrosis of any carpal bone.

Most carpal dislocations occur in the lunate bone or around it (perilunate). An isolated dislocation of the carpal scaphoid is a rare injury. We report a case of a palmar scaphoid dislocation combined with a dorsal perilunate dislocation, which was treated with open reduction, fixed with two Kirschner wires and ligament repair, with a good result.

Introduction: The scapholunate ligament (SLL) injury can cause wrist pain and instability. There is a wide variety of surgical techniques used for the treatment this lesion, such as dorsal capsulodeses, tenodeses with flexor or extensor tendons, bone-ligament-bone graft.
 Objective: To describe new technique SLL aiming to stabilize dissociated carpus double capsulodesis.

INTRODUCTION Kienböck's disease is a condition of osteonecrosis of the lunate bone in the hand, and most patients present with a painful and sometimes swollen wrist with a limited range of motion in the affected wrist. Vaughan-Jackson syndrome is characterized by the disruption of the digital extensor tendons, beginning on the ulnar side with the extensor digiti minimi and extensor digitorum co...

BACKGROUND To determine the association between lunate morphology and the scapholunate instability using radiographic images, and investigate the association between lunate morphology and scaphoid fracture location. METHODS Between January 2003 and December 2011, we retrospectively evaluated the plain radiographs and computed tomography (CT) images of 70 patients who underwent surgical interv...

OBJECTIVE the aim of this study is try to show the best view for distal radius fractures so called die-punch fractures. METHODS There has been used a human cadaver radius bone from the Salvador Arena Tissue Bank. This bone was cleaned up after removing the soft tissues and osteotomies created displaced lunate fossa fractures of 0, 1, 2, 3 and 5 mm. We have fixed this fragment with adhesive ta...

INTRODUCTION The aim of the present study was to assess the prevalence and characteristics of subclinical arthritis of carpal and metacarpophalangeal joints in patients with systemic sclerosis (SSc). METHODS Low-field (0.2 T) magnetic resonance imaging (MRI) was performed in consecutive patients with SSc attending our center between January 2010 and March 2011. Results were assessed in a stan...

The aim of this study was to identify possible anatomical risk factors for Kienbock's disease. We measured on a posteroanterior radiograph of the wrist, in zero-position, the Lunate Diameter and Height, Lunate Tilting Angle, Lunate Uncovering Index, Lunate Fossa Inclination, Radial Inclination and Ulnar Variance. We measured these seven parameters on the unaffected hand in the Kienböck group (N...
