In the distal radius fracture requires radiographic views that allow you to see the articular surface without interposition. The objective was to determine whether lateral radiographic projections 7 and 22° improve the analysis of this surface. METHOD: Case series study with radiographs of healthy and operated patients, in order to identify the lunate and scaphoid facets in lateral and anteroposterior projections. Qualitative analysis was made on the radiographs of the distal radius with wedges of 7 and 22° in the lateral views and 11° in the anteroposterior view...

Aim To evaluate the outcome of these complex fractures using a volar approach and the DePuy Synthes variable-angle 2.4-mm distal radius rim plate. This plate is precontoured to the volar rim for placement distal to the watershed line allowing purchase of the rim fragment of the lunate facet. Its low profile and smooth edges are designed to minimize flexor tendon irritation. Method We report on a consecutive series of far distal AO-23B3 and AO-23C3 fractures treated using this plate in a tertiary hand center between November 2011 and May 2014...

Traumatic lunate fractures are very rare and those treatments require an understanding of anatomical features. We present a case of an ulnolunate ligament avulsion fracture of the lunate that was successfully repaired by surgical fixation with open reduction and internal fixation. We believe that restoration of ulnolunate ligament function is important to prevent further deterioration of wrist function after this injury.

Background Flexion and extension of the wrist is achieved primarily at the radiocarpal and midcarpal joints. Carpal kinematics have been investigated, although there remains no consensus regarding the relative contribution of each bone to wrist motion. Purpose To determine the kinematics of the scaphoid, lunate, and capitate during unconstrained simulated wrist flexion/extension and to examine the effect of motion direction on the contribution of each bone. Materials and Methods Seven cadaveric upper extremities were tested in a passive wrist simulator with 10N tone loads applied to the wrist flexors/extensors...

It is widely hypothesized that mechanical loading, specifically repetitive low-intensity tasks, influences the inner structure of cancellous bone. As such, there is likely a relationship between handedness and bone morphology. The aim of this study is to determine patterns in trabecular bone between dominant and non-dominant hands in modern humans. Seventeen healthy patients between 22 and 32 years old were included in the study. Radial carpal bones (lunate, capitate, scaphoid, trapezium, trapezoid, 1st, 2nd and 3rd metacarpals) were analyzed with high-resolution micro-computed tomography...

BACKGROUND: Interpreting the structure in the wrist is complicated by the existence of multiple joints as well as variability in bone shapes and anatomical patterns. Previous studies have evaluated lunate and capitate shape in an attempt to understand functional anatomical patterns. OBJECTIVE: The purpose of this study was to describe anatomical shapes and wrist patterns in normal wrist radiographs. We hypothesized that there is a significant relationship in the midcarpal joint with at least one consistent pattern of wrist anatomy...

This article examines the purpose of the post-mortem in the late Victorian asylum and discusses what the findings reveal about contemporary understanding of mental health. By examining the practice at the Littlemore Asylum of Oxford, the definition of the asylum post-mortem will be questioned and issues of consent and ownership of the dead body explored. It will be argued that the purpose of the examination was partly to appease the demands of the Commissioners in Lunacy, to protect the asylum against accusations of malpractice, and to appease the resident assistant medical officer's own morbid curiosity...

Spiegelian hernia is a rare anterior abdominal wall hernia, described in 1764 by a Hungarian surgeon. It often remains undiagnosed because of its unusual location on the semilunar line, laterally to the rectus muscle. CT presentation is specific. Because of its high risk of strangulation, a surgical management should be proposed, even in case of fortuitous discovery. We present three cases of Spiegelian hernia, two fortuitously discovered and one detected on the occasion of a small bowel incarceration. We also evoke a similar case of eventration on the lunate line requesting the knowledge of the detailed surgical antecedents for diagnosis...

A technique for using an x-ray detectable radiopaque element from a surgical sponge to assess the adequacy of debridement of carpal bone cysts, Kienböck disease (lunate avascular necrosis), enchondroma of the digits, and scaphoid nonunions is described. The technique is simple to perform, inexpensive, and presents minimal additional risk to the patient. The technique has been used over the past 16 years and has enabled adequate debridement of these hand and wrist maladies by radiographically demonstrating the adequacy of the debridement to be bone grafted...

Carpal tunnel syndrome is among the most frequently diagnosed forms of peripheral nerve compression. Carpal tunnel syndrome due to carpal collapse that had progressed over decades, with a palmarly dislocated lunate, is rare. Hints of past trauma to the wrist going back decades should prompt further radiological examination in case of recurrent median nerve compression. With sufficient preoperative evaluation, the causes can be accurately detected and treated. Therefore, precise and complete history-taking is mandatory...

London County Council's pathological laboratory in the LCC asylum at Claybury, Essex, was established in 1895 to study the pathology of mental illness. Historians of psychiatry have understood the Claybury laboratory as a predecessor of the Maudsley Hospital in London: not only was this laboratory closed when the Maudsley was opened in 1916, but its director, Frederick Walker Mott, a champion of the 'German' model in psychiatry, was instrumental in the establishment of this institution. Yet, as I argue in this essay, for all the continuities with the Maudsley, the Claybury laboratory should not be seen solely as its predecessor - or as a British answer to continental laboratories such as Theodor Meynert's in Vienna...

Vascularized small-bone grafting is an efficient and often necessary surgical approach for nonunion or necrosis of several bones in particular sites of the body, including scaphoid, lunate, distal ulna, and clavicle. The medial femoral condyle is an excellent graft source that can be used in treating scaphoid, ulna, clavicle, or lower-extremity bone defects, including nonunion. Vascularized bone grafting to the small bones, particularly involving reconstruction of damaged cartilage surfaces, should enhance subchondral vascular supply and help prevent cartilage regeneration...

REVIEW
James P Higgins, Heinz K Bürger
Vascularized osteochondral flaps are a new technique described for the reconstruction of challenging articular defects of the carpus. The medial femoral trochlea osteochondral flap is supplied by the descending geniculate artery. This osteochondral flap has shown promise in the treatment of recalcitrant scaphoid proximal pole nonunions and advanced avascular necrosis of the lunate. The anatomy, surgical technique, and results are discussed, with clinical cases provided.

Kienböck disease is an aseptic osteonecrosis of the lunate, which gradually leads to total carpal collapse. Lichtman's classification relates radiographic evidence of wrist damage to four different stages and supports surgical decision-making. This study pertains to six patients (2 males and 4 females) affected by stage IV Kienböck's disease who underwent proximal row carpectomy and received an RCPI implant. The clinical outcomes consisted of wrist range of motion (ROM), pain on a VAS scale (0-10), the DASH score and the patient's level of satisfaction...

Nguyen Van Minh, Yuzuru Hamada
OBJECTIVES: The degree of expression of sulcal patterns on endocasts of nonhuman primates has been shown to depend primarily on species (brain size) and age of the individual. It has been suggested that brain details on endocasts are reproduced better in juvenile than adult primates. Here, we investigated age-related changes in the imprint of the major sulci on the endocranium of Japanese macaques (Macaca fuscata) from the juvenile period to adulthood. MATERIALS AND METHODS: Using CT scans of 25 (12 males, 13 females) cranial specimens from macaques, we generated virtual endocasts to assess imprints of the seven main sulci on the endocranial surface...

OBJECTIVES: This study aims to investigate whether or not it is possible to avoid intra-articular screw penetration in the application of distal radius volar plate with minimal use of fluoroscopy and thereby reduce to a minimum the risk of exposure of the surgical team to radiation. PATIENTS AND METHODS: Volar plate with distal screw application with minimal use of fluoroscopy was performed in a total of 50 patients (22 males, 28 females; mean age 43.52 years; range 18 to 76 years) with unstable distal radius fracture following reduction of fracture between June 2014 and May 2016...

Kienböck disease typically presents with wrist pain, swelling, restricted range of motion, and difficulty in performing activities of daily living. Because the etiology and evolution of disease remain unclear, broad ranges of treatments have been designed. Percutaneous cementoplasty is expanding its role for managing painful bone metastases outside the spine. We can draw a parallel between lytic tumoral lesions and Kienbock's disease. Increasing the strength and rigidity of lunate with cementoplasty can prevent it from collapse, relieve the symptoms associated with the process of avascular necrosis, and increase the wrist range of motion...

Madelung deformity is an abnormality of the distal part of the forearm due to a growth arrest in the distal radial physis creating an increase of the radial tilt angle associated with a dorsal subluxation of the distal ulna in most cases. It is a rare condition which represents only 1.7% of hand deformities being characterized by the presence of an abnormal structure, Vickers ligament, that tethers the distal radius to the lunate bone. Although it is believed to be a congenital disorder, the symptoms are absent till late childhood...

In recent years there has been growing acknowledgement of the place of workhouses within the range of institutional provision for mentally disordered people in nineteenth-century England. This article explores the situation in Bristol, where an entrenched workhouse-based model was retained for an extended period in the face of mounting external ideological and political pressures to provide a proper lunatic asylum. It signified a contest between the modernising, reformist inclinations of central state agencies and local bodies seeking to retain their freedom of action...
