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...

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...

Background Three-dimensional (3D) printing has developed as a revolutionary technology with the capacity to design accurate physical models in preoperative planning. We present our experience in surgeon-based design of 3D models, using home 3D software and printing technology for use as an adjunct in vascularized bone transfer. Methods Home 3D printing techniques were used in the design and execution of vascularized bone flap transfers to the upper extremity. Open source imaging software was used to convert preoperative computed tomography scans and create 3D models...

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 challenging cases of difficulty in fixation of the VLF fragment in distal radius fracture. For this fracture type, it is most important to identify the volar ulnar bone fragment before surgery; it may also be necessary to optimize distal placement of the VLP via a dual-window approach and to apply additional fixations, such as a small plate, anchor, and/or external fixation...

In this study, document analysis is used to examine case books from the Beechworth Lunatic Asylum with the aim of determining the extent of family involvement in patients' admission and discharge. There were 420 male and 278 female patients admitted in the study period, with over half transferred from other Victorian asylums. Next of kin were identified for 64% of male and 84% of female patients. Families were involved in the admission of 52 (12%) male and 50 (18%) female patients, usually by bringing patients to the asylum or providing evidence of behavioural changes...

This article looks into the establishment and development of two criminal asylums in Norway. Influenced by international psychiatry and a European reorientation of penal law, the country chose to institutionalize insane criminals and criminally insane in separate asylums. Norway's first criminal asylum was opened in 1895, and a second in 1923, both in Trondheim. Both asylums quickly filled up with patients who often stayed for many years, and some for their entire lives. The official aim of these asylums was to confine and treat dangerous and disruptive lunatics...

This article explains how old, poor people living with dementia came to be institutionalised in 19th-century Britain (with a focus on London), and how they were responded to by the people who ran those institutions. The institutions in question are lunatic asylums, workhouses and charitable homes. Old people with dementia were admitted to lunatic asylums, workhouses and charitable homes, but were not welcome there. Using the records of Hanwell lunatic asylum, published texts of psychiatric theory, and the administrative records that all of these institutions generated at local and national levels, this article argues that 'the senile' were a perpetual classificatory residuum in the bureaucracy of 19th-century health and welfare...

We report about a dorsal dislocation of the lunate accompanied by a trapezoid fracture in a 41-year old male patient after a motorcycle accident. The lunate dislocation with no dorsal or volar intercalated segment instability (DISI, VISI) was diagnosed by x-ray whereas the trapezoid fracture was only diagnosable by computed tomography. A closed reduction and internal fixation of the lunate by two Kirschner wires was performed, the trapezoid fracture was conservatively treated. Surgery was followed by immobilization, intense physiotherapy and close follow-up...

OBJECTIVE: Wrist joint space narrowing is a main radiographic outcome of rheumatoid arthritis (RA). Yet, automatic radiographic wrist joint space width (JSW) quantification for RA patients has not been widely investigated. The aim of this paper is to present an automatic method to quantify the JSW of three wrist joints that are least affected by bone overlapping and are frequently involved in RA. These joints are located around the scaphoid bone, viz. the multangular-navicular, capitate-navicular-lunate, and radiocarpal joints...

OBJECTIVE: To investigate the relationship between electrodiagnosis and various ultrasonographic findings of carpal tunnel syndrome (CTS) and propose the ultrasonographic standard that has closest consistency with the electrodiagnosis. METHODS: Ultrasonography was performed on 50 female patients (65 cases) previously diagnosed with CTS and 20 normal female volunteers (40 cases). Ultrasonography parameters were as follows: cross-sectional area (CSA) and flattening ratio (FR) of the median nerve at the levels of hamate bone, pisiform bone, and lunate bone; anteroposterior diameter (AP diameter) of the median nerve in the carpal tunnel; wrist to forearm ratio (WFR) of median nerve area at the distal wrist crease and 12 cm proximal to distal wrist crease; and compression ratio (CR) of the median nerve...

Background It has been over 100 years since the initial description of avascular necrosis of the lunate. Over the last two decades, there has been the introduction of advanced information regarding the etiology, natural history, classification, and treatment options for lunate osteonecrosis. There have been new classifications developed based on advanced imaging, perfusion studies of lunate viability, and arthroscopic assessment of the articular cartilage. Purpose This article brings together a new treatment algorithm, incorporating the traditional osseous classification system (Lichtman) with the perfusion/viability classification (Schmitt) and the articular cartilage classification (Bain)...
