Background: Scaphoid fracture is the most common among carpal bone fractures, frequently imperceptible on initial radiographs. Tendency of scaphoid fracture to undergo in non-union makes it an important challenging injury for all orthopaedic surgeons. Displaced scaphoid fracture has high non-union rate in conservative management asserting the need to explore operative treatment. Materials and method: A prospective study was conducted in our institution in thirty patients in 20 to 50 year age group, for displaced scaphoid fracture (<30 days duration)...

BACKGROUND: Perilunate dislocations and fracture-dislocations are a subcategory of the carpal instability complex. Herein, we report our university hospital experience with this complex injury. The goal of our study was to find predictive factors and quantify the development of arthritis and lunate necrosis. We tried to measure the impact of arthritis on hand function. METHODS: Between January 2000 and December 2014, 21 patients underwent surgery for perilunate dislocations and perilunate fracture-dislocations of the wrist in our tertiary university center...

Clear definitions of 'normal' equine gestation length (GL) are elusive, with GL being subject to a considerable number of internal and external variables that have confounded interpretation and estimation of GL for over 50 years. Consequently, the mean GL of 340 days first established by Rossdale in 1967 for Thoroughbred horses in northern Europe continues to be the benchmark value referenced by veterinarians, breeders and researchers worldwide. Application of a 95% confidence limit to reported GL range values indicates a possible connection between geographic location and GL...

Introduction: The anterior perilunate dislocations of the carp (PDC)are exceptional and poorly known lesions, which may go unnoticed in an emergency. They derive their importance from the severity of sequelae, which are dominated by chronic wrist instability and long-term osteoarthritis. Case Report: We report the case of an open anterior PDC with no carpal fracture in a young patient. The injury occurred in a road accident and was treated at once with satisfactory results 1year after...

BACKGROUND: Considering articular distal radius fractures treated with volar plate, we hypothesized that articular radio-carpal displacement was better reduced with arthroscopic control than with only fluoroscopic control. METHODS: Forty patients with similar articular radius fracture (type C according to AO classification) and high functional needs were treated with volar plate fixation. They were divided in two comparative groups: 20 patients in Fluoroscopic group and 20 patients in Arthroscopic group...

Scaphoid fractures are the most common fractures of the carpal bones, corresponding to 60%. Of these, 10% progress to nonunion; moreover, 3% can present necrosis of the proximal pole. There are various methods of treatment using vascularized and non-vascularized bone grafts. To evaluate and compare the rate of scaphoid consolidation with necrosis of the proximal pole using different surgical techniques. The authors conducted a review of the literature using the following databases: PubMed and BIREME/LILACS, where 13 case series were selected (ten with use of vascularized bone grafts and three of non-vascularized bone grafts), according to inclusion and exclusion criteria...

Scaphoid non-union management is still a challenge in clinical practice for orthopaedic surgeons. Though several treatment methods have been described, there is an ongoing debate about optimum management. Based on new concepts about avascular conditions, promising results were reported with metaphyseal decompression of the distal radius by increasing the vascularization of the radial column of the carpus. We aimed to evaluate the clinical, radiological, and functional outcomes of distal radius core decompression and fixation with palmar percutaneous cannulated compression screws without grafting in patients with scaphoid waist fracture non-union...

Temminck's ground pangolin is the only pangolin present in South Africa. It is a myrmecophagous mammal with a bipedal gait. The thoracic limbs are used to break open ant nests, dig for food, and expand previously occupied burrows. This study describes the osteology and radiological anatomy of the thoracic limbs of this threatened species. Thoracic limbs from four Temminck's ground pangolins, which succumbed from electrocution or natural causes, were digitally radiographed in situ. The individual bones were then cleaned, described and digitally radiographed...

REVIEW
David Pope, Peter Tang
Carpal tunnel syndrome (CTS) after distal radius fractures can present in 3 forms: acute, transient, and delayed. Acute CTS requires an emergent carpal tunnel release. Many patients with transient CTS after distal radius fracture do not require surgical release of the carpal tunnel once the fracture is repaired. Prophylactic carpal tunnel release in the absence of signs and symptoms of CTS after a distal radius fracture is not indicated. For patients with delayed CTS after a distal radius fracture, all possible causes of nerve compression should be considered and addressed in standard fashion...

Ramin Mandegaran, Sam Gidwani, Ali Zavareh
OBJECTIVE: The scaphoid is the most commonly fractured carpal bone. The presence of a concomitant hook of hamate fracture is of particular relevance given that it is often occult on routine wrist/scaphoid radiographs and that hook of hamate fractures are prone to symptomatic non-union, resulting in chronic ulnar wrist pain. Prompt diagnosis and immobilisation/fixation may minimise such complications. Our study is aimed at assessing the frequency of concomitant hook of hamate fractures in patients with scaphoid fractures...

The aim of this study was to analyse lunate fractures and any associated osseo-ligamentous injuries. A systematic review identified 34 cases. We identified carpal instabilities at the radiocarpal and midcarpal joints in volar and dorsal directions. Radiocarpal instabilities (10/34) were usually dorsoradial (8/10), with a transverse lunate fracture, best seen on a coronal image. Midcarpal instabilities (24/34) were usually volar (14/18), with a volar lunate shear fracture, best seen on a sagittal image. Instabilities were sub-classified into non-displaced, subluxated and dislocated...

Christophe L Mathoulin, Margareta Arianni
Treatment of scaphoid fractures has been focused mainly on achieving union, with less attention to restoring normal scaphoid shape and orientation. Malalignment of one carpal bone will disrupt the kinetics of the entire wrist. The dorsal intercalated segment instability deformity associated with scaphoid waist nonunion is a nondissociative form of carpal instability. It has to be reduced in the treatment of scaphoid waist nonunions to avoid kinetic problems that will lead to arthritic changes. Computerized tomography scanning has become indispensable to visualize the humpback deformity clearly...

Radial styloidectomy along with scaphoid nonunion reconstructive surgery is considered an acceptable surgical treatment for stage 1 scaphoid nonunion advanced collapse. The extent of radioscaphoid joint wear that defines scaphoid nonunion advanced collapse stage 1 is unclear. An appropriate radial styloidectomy is limited to 6 mm styloid removal to prevent carpal instability. The aim of this study was to determine whether nonunion fracture location can be a guiding factor in determining whether the scaphoid bone can be retained with scaphoid nonunion reconstructive surgery and radial styloidectomy...

BACKGROUND: Volar plate fixation of distal radius fractures can result in soft tissue injuries. Abnormal contour of the dorsal cortex of the distal radius provides difficulties in discerning screw penetration on standard radiographs. The skyline and carpal shoot-through views are additional views to improve dorsal cortex visibility. We report on the sensitivity and specificity of determining screw protrusion with these views. METHODS: Seven fresh frozen cadavers were instrumented with a distal radius volar locking plate...

This meta-analysis compared outcomes between percutaneous pinning/wiring and open reduction internal fixation (ORIF) with locking plates for treatment of unstable distal radius fractures. Medline, Cochrane, EMBASE, and Google Scholar were searched through December 30, 2015. Twenty randomised controlled trials (RCTs) and non-randomised two-arm studies were included. Outcomes included scores of Disabilities of the Arms, Shoulders and Hands (DASH), visual analogue scale (VAS) pain, and patient rated wrist evaluation (PRWE) score, as well as range of motion (ROM) and complication incidence...

INTRODUCTION: Hamulus fractures are uncommon injuries constituting 2-4% of carpal fractures and are usually reported in athletes. Stress fractures of hamulus are even rarer and very few cases have been reported till date. In this case report, we present the first documented case of stress fracture of hamulus in a cricket batsman and review the existing literature on hamulus fractures, both acute and stress fractures, in sportspersons in general. CASE REPORT: A 23-year-old, right-handed, cricket batsman presented with pain in the hypothenar region of his left hand of 7 weeks duration...

INTRODUCTION: Open reduction and internal fixation (ORIF) with plate and screws represents the recommended treatment for unstable intra-articular distal radius fractures. Although significant progresses in surgical technique have been made, anatomical reconstruction of radio-carpal articular surface still represent a difficult task, especially in multifragmentary fractures. Available PEEK reinforced-carbon fiber composite radiolucent devices allow both an easier and more careful assessment of intra-operative reduction of the articular surface of distal radius and prompt correction of any residual step deformity...

OBJECTIVE: This case-control study was designed to test the hypothesis whether carpal tunnel release (CTR) during fixation of distal radius 23-C2 AO fractures improves outcomes. METHODS: Thirty-five consecutive patients who sustained distal radius fractures of the dominant hand participated in this study. Patients were allocated into two groups: (a) The ORIF + CTR (16 patients (11 males and 5 females)); (b) the ORIF and NOT CTR 19 patients (12 males and 7 females)...

This study aimed to evaluate whether radiographic abnormalities at yearling sales were associated with the failure to start racing at 2-3 years of age. Radiographic abnormalities in the carpal (n=852), tarsal (n=976), metacarpophalangeal (n=1,055), and metatarsophalangeal joints (n=1,031) from 1,082 horses, recorded at yearling sale, were reviewed. Eighty-two horses (7.6%) failed to start racing. Radiographic abnormalities such as wedged or collapsed tarsal bones, irregular lucency of a sagittal ridge at the distal aspect of the distal third metatarsal bone, and proximal dorsal fragmentation of the first phalanx in metatarsophalangeal joints were associated with failure to start racing in these horses...
