The position of the lunate sulcus in fossil endocasts (when it can be determined) may serve as a potential marker of cognitive development in extinct hominid species. While the lunate sulcus is reliably present in the brains of great apes and forms the anterolateral boundary of the primary visual cortex, in humans its presentation is much more variable, and even if present, it does not correspo...

Perilunate Dislocation Anterior-posterior (AP) view (Figure 1) demonstrates the distal and proximal carpal rows overlapping, as well as a complete radial styloid fracture. Lateral view (Figures 2 and 3) demonstrates dorsal dislocation of the capitate, whereas the lunate remains articulated with the radius. More often seen in young men in their teens to twenties, rather than children or the elde...

Recent reports suggest the presence of a rare fracture type for which reduction and fixation cannot be achieved with volar locking plate (VLP). In particular, it is difficult to achieve reduction and fixation with volar lunate facet (VLF) fragments present on the volar ulnar aspect of the lunate facet, because of the anatomical structure and biomechanics in this region. Herein, we report two ch...

Perilunate dislocations are a devastating injury to the carpus that carry a guarded long-term prognosis. Mayfield type 4 perilunate dislocations are rare, high-energy injuries that carry a risk for avascular necrosis (AVN) of the lunate. When AVN ensues and the carpus collapses, primary treatment with a proximal row carpectomy or arthrodesis has been advocated. This case reports a successful cl...

We present an extreme rare case of traumatic partial avascular necrosis of the lunate after palmar perilunate dislocation with lunate fracture. A 32-year-old female was injured by motorcycle accident with palmar perilunate fracture dislocation and lunate fracture. Scapholunate and lunotriquetrum dislocations were reduced and fixed temporarily. The torn dorsal ligament was repaired. Considering ...

The present study examines the gross anatomical features of anomalous lunate sulcus detected incidentally in a cadaveric brain and discusses its clinical importance. The absence of lunate sulcus was carefully studied in a dissected brain specimen. The absence of lunate sulcus was observed unilaterally on the right side of a cadaveric brain specimen. The lunate sulcus was clearly appreciated on ...

Introduction: Avascular necrosis of the lunate bone was described in 1910 by Austrian radiologist Robert Kienböck, which is named after him. A mixture different factors such as mechanical, vascular and genetic predisposition may be related to pathogenesis this disease. As for natural evolution disease, failure early diagnosis treatment lead a gradual from stage I IV, causing discomfort patient....

Introduction Painful destruction of the wrist as a consequence of scaphoid non-union advanced collapse (SNAC) or chronic advanced scapho-lunate dissociation (SLAC) is a challenge to treat. In the late stages of either condition, only salvage procedures can be discussed. The option of proximal row carpectomy (PRC) only remains available in stage II, when the mid-carpal joint is still preserved a...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013009429 DESCRIPTION A 40-year-old woman presented to our orthopaedic clinic with left-sided wrist pain after falling. On physical examination, there was no limitation in range of motion of the wrist; however, flexion and extension were minimally painful. There was no ...
