PURPOSE OF THE STUDY Our study aimed to evaluate a group of patients who in the period from 2005 to 2014 underwent a four-corner arthrodesis of the wrist in our department. We also wanted to verify the hypothesis as to whether the use of conventional dorsal plate without the application of bone grafts leads to comparable results as the use of dorsal locking plates and routine application of bone grafts. MATERIAL AND METHODS Throughout the years 2005 to 2014 the four-corner arthrodesis of the wrist was performed in our department in a total of 62 patients, in two cases bilaterally...

The 'mad-doctor' Dr Francis Willis achieved national and international celebrity following his successful treatment of King George III's first major episode of insanity in 1788-9. At the time of his summons to attend the King, Willis was a well-established provincial practitioner and madhouse proprietor. An anonymous French visitor published a description of Willis's Lincolnshire madhouse and his therapeutic practices in 1796. The translated text of the full article provides a unique insight into the work of a key figure in the historical development of psychological medicine...

K C Kapil Mani, Parimal Acharya
PURPOSE: Conventional bone grafting and Herbert screw fixation give satisfactory results for scaphoid nonunion; however, vascularized bone grafting has superior results, especially in the case of avascular necrosis of proximal fragment. Vascularized bone grafting is technically more demanding with small error of margin, problems of getting the appropriate graft, fixation and incorporation, and requires longer duration for wrist immobilization. METHODS: Forty-five patients of scaphoid nonunion were treated by cancellous bone grafting, cortex containing graft if required and Herbert screw fixation...

Gustavo Mantovani Ruggiero
Injury to the flexor pollicis longus (FPL) tendon is one of the most frequent complications when fixing distal radius fractures with the volar locking plates. The author proposed a simple surgical technique providing a reliable soft tissue protection to prevent friction on the FPL with the volar locking plate, using a flap of the FCR sheath sutured to attachments of the volar capsule on the lunate buttress facet of the distal radius.

BACKGROUND: In vertebrate embryos, a "segmentation clock" times somitogenesis. Clock-linked genes, including Lunatic fringe (Lfng), exhibit cyclic expression in the presomitic mesoderm (PSM), with a period matching the rate of somite formation. The clock period varies widely across species, but the mechanisms that underlie this variability are not clear. The half-lives of clock components are proposed to influence the rate of clock oscillations, and are tightly regulated in the PSM. Interactions between Lfng and mir-125a-5p in the embryonic chicken PSM promote Lfng transcript instability, but the conservation of this mechanism in other vertebrates has not been tested...

PURPOSE: To identify factors influencing overall radiologic changes in the distal radioulnar joint after ulnar shortening osteotomy (USO) in patients with idiopathic ulnar impaction syndrome. MATERIALS AND METHODS: A total of 310 patients who had undergone USO between May 2007 and December 2013 were included in this retrospective case-control study. The patients were classified into two groups (with or without radiologic findings of new arthritic changes), after which the following factors were analyzed: 1) demographic factors; 2) radiologic aspects, including ulnar variance (UV), morphological DRUJ type (classified according to Tolat et al...

PURPOSE: To evaluate the diagnostic utility of scaphoid dorsal subluxation on magnetic resonance imaging (MRI) as a predictor of scapholunate interosseous ligament (SLIL) tears and compare this with radiographic findings. METHODS: Thirty-six MRIs were retrospectively reviewed: 18 with known operative findings of complete Geissler IV SLIL tears that were surgically repaired, and 18 MRIs performed for ulnar-sided wrist pain but no SLIL tear. Dorsal subluxation of the scaphoid was measured on the sagittal MRI cut, which demonstrated the maximum subluxation...

The distal forelimb (autopodium) of quadrupedal mammals is a key morphological unit involved in locomotion, body support, and interaction with the substrate. The manus of the tapir (Perissodactyla: Tapirus) is unique within modern perissodactyls, as it retains the plesiomorphic tetradactyl (four-toed) condition also exhibited by basal equids and rhinoceroses. Tapirs are known to exhibit anatomical mesaxonic symmetry in the manus, although interspecific differences and biomechanical mesaxony have yet to be rigorously tested...

Hippocampal neural stem cells (NSCs) integrate inputs from multiple sources to balance quiescence and activation. Notch signaling plays a key role during this process. Here, we report that Lunatic fringe (Lfng), a key modifier of the Notch receptor, is selectively expressed in NSCs. Further, Lfng in NSCs and Notch ligands Delta1 and Jagged1, expressed by their progeny, together influence NSC recruitment, cell cycle duration, and terminal fate. We propose a new model in which Lfng-mediated Notch signaling enables direct communication between a NSC and its descendants, so that progeny can send feedback signals to the 'mother' cell to modify its cell cycle status...

BACKGROUND: Scapholunate ligament injury is a commonly occurring carpal ligament injury. Pathology associated with scapholunate ligament injury depends on several factors such as the time after injury, type of injury (instability) and the development of osteoarthritis. The aim of this study was to investigate and compare contact mechanics in the lunocapitate and scaphocapitate joints in the normal, injured (scapholunate dissociation) and repaired (postoperative) wrist. METHODS: Four human subjects with scapholunate ligament dissociation participated in this study...

INTRODUCTION: Avascular necrosis (AVN) of the bones of the wrist most commonly involves the lunate followed by the proximal pole of the scaphoid and the capitate. Trapezium avascular necrosis is extremely rare with only two cases reported in the literature, both of which were treated surgically. In this article, we report a unique case of trapezium avascular necrosis treated conservatively. CASE PRESENTATION: A 38-year-old man complaining of a 4-month history of mild pain on the base of his right thumb...

Kienbock's disease, or avascular necrosis of the lunate, is a progressive disease ultimately resulting in end-stage arthrosis of the wrist. Various surgical treatments are available for different Lichtman stages of disease. We review the surgical options and indications, expected radiologic post-operative appearance, as well as detail potential surgical complications, as they relate to Kienbock's disease.

Radial club hand is a complex congenital abnormality of the radial or pre-axial border of the upper extremity. It has a wide range of phenotypes from hypoplasia of the thumb to complete absence of the radius and the first ray. Centralization with tendon transfer is a popular method for maintaining the correct position of radial club hand. On the other hand, various corrections were devised, e.g. radialization after distraction to emphasize the fact that the head of the ulna is positioned under the radial carpal bones and is no longer placed in a slot in the center of the carpus, microvascular epiphysis transfer, gradual correction using Ilizarov method, for Bayne Type III or Type IV...

In order to study the microstructure characteristics of normal lunate bones, eight fresh cadaver normal lunates were scanned with micro-computed tomography. High-resolution images of the micro-structure of normal lunates were obtained and we analyzed the nutrient foramina. Then nine regions of interest (ROI) were chosen in the central sagittal plane so that we could obtain the parameters of trabecular bones of ROIs. The distal lamellar-like compact structure had statistically significant differences when it was compared with the ROIs in the volar and dorsal ends of the distal cortex...
