Abstract
 Background: In this study, we examined whether carpal bones (lunate, hamate, capitate) morphologies and fourth metecarp-capitate articulation have an effect on the distal radius fracture pattern.
 
 Methods: 206 patients who applied to emergency department with between 2016-2020 were included in study. Preoperative pre-reduction x-ray films of examined. Lunate, capitate...

The aim of this study was to identify anatomic risk factors for scapholunate dissociation. On a PA view of the wrist, in zero position, the scaphoid and lunate diameter and height, lunate tilting angle, lunate uncovering index, lunate fossa inclination, radial inclination and ulnar variance were measured; on a lateral view the scapholunate angle and palmar tilting angle were measured. In a cont...

A rare case of radiocarpal dislocation is presented. The lunate and proximal pole of the scaphoid were displaced in a volar and proximal direction. The injury was missed initially and the patient was subsequently operated on six weeks later. Open reduction and internal fixation of the scaphoid was performed and this was followed by an uneventful postoperative period, with a satisfactory functio...

Fig. 2. A preoperative T2-weighted magnetic resonance imaging image revealed a high signal intensity in the lunate. Fig. 1. A 40-year-old woman presented with pain in the dorsal aspect of the right wrist. Im ag es droma shows a round, transparent osteolytic bony change [2]. It is generally asymptomatic, but may expand [3]. Although enlargement of enchondroma with cortical thinning and protrusio...

Kienbock's disease, which is an idiopathic osteonecrosis and collapse of the lunate bone, is an uncommon disease in children. This report describes a case of an 11-year-old girl, who presented with avascular necrosis of lunate bone confirmed by radiographic and magnetic resonance imaging evidence. After a short period of casting, the case was fully recovered within one year. The signal change w...

Kienbock's disease, or osteonecrosis of the lunate, can lead to chronic, debilitating wrist pain. Etiologic factors include vascular and skeletal variations combined with trauma or repetitive loading. In stage I Kienbock's disease, plain radiographs appear normal, and bone scintigraphy or magnetic resonance imaging is required for diagnosis. Initial treatment is nonoperative. In stage II, scler...

Posttraumatic instability of the wrist, resulting in scapholunate dissociation, is a common injury pattern in the wrist [2]. Mayfield et al. [1] described instability progressing sequentially from a scapholunate interosseous ligament (SLIL) tear to complete ligament failure around the lunate, resulting in lunate dislocation. Linscheid et al. [4] also demonstrated that excision of the dorsal rad...

  Background: Abnormal angulation of the lunate can be an indication of intercarpal pathology. On magnetic resonance images (MRIs) the lunate often looks dorsally angulated, even in healthy wrists. The tilt on individual slices can also be different and might be misinterpreted as pathological, contributing to inaccurate diagnoses and unnecessary surgery. The primary aim of this study was to det...
