RATIONALE: Idiopathic avascular necrosis of the scaphoid or lunate bone are known as Preiser disease and Kienböck disease, respectively. Although there are reports of avascular necrosis involving more than one carpal bone, concurrent idiopathic avascular necrosis of the scaphoid and lunate bones is rare, with only five cases reported in the English literature (including the two herein). Although the optimum treatment for Preiser disease with concomitant Kienböck disease has not been established, our cases underwent closed radial wedge osteotomy based on the evidence of satisfactory outcomes for treating Kienböck disease...

Previous 2D studies have shown that there is a spectrum of carpal mechanics that varies between row-type motion and column-type motion as a function of wrist laxity. More recent 3D studies have suggested instead that carpal bone motion is consistent across individuals. The purpose of this study was to use 3D methods to determine whether carpal kinematics differ between stiffer wrists and wrists with higher laxity. Wrist laxity was quantified using a goniometer in 10 subjects by measuring passive wrist flexion-extension range of motion...

Scaphoid non-union affects wrist joint function and is often associated with a predictable pattern of degenerative change. A 30-year-old man presented with a symptomatic 15-year-old right scaphoid fracture with secondary scaphoid non-union advanced collapse of his right wrist. There was no evidence of avascular necrosis. The initial injury was from a fall onto his outstretched hand. We performed a right scaphoid open reduction, internal fixation and iliac crest bone graft. One year after the operation, the patient had good wrist function and grip strength...

Hand and wrist radiographic indexes such as radial inclination, ulnar variance, carpal height ratio, and radial tilt play an important role in the diagnosis and management of medical disorders, so they should be modified regarding the population and race difference. This study aims to compare the normal radiologic wrist indexes in Mashhad population with other existing databases and define some of the factors that may influence the normal radiographic indexes. A total of 100 healthy participants were enrolled in this prospective cross-sectional study...

INTRODUCTION: To percutaneously fixate a midwaist scaphoid fracture, both volar and dorsal approaches are considered valid options although they may have different screw insertion angles relative to the scaphoid fracture plane influencing fixation stability. In this virtual simulation study, we investigated the accessibility of placing a screw perpendicular to the fracture plane in transverse and horizontal oblique scaphoid midwaist fracture models and compared standard volar and dorsal approaches...

INTRODUCTION: Scaphoid fractures in the pediatric population represent ∼3% of all hand and carpal fractures. Cast immobilization has been shown to yield excellent results in the acute phase, however some patients develop nonunions. Currently, there is no consensus regarding the best surgical treatment after development of a pediatric/adolescent scaphoid nonunion. METHODS: A comprehensive literature review was performed utilizing Medline, Ovid, and Embase databases to compare surgical techniques for adolescent scaphoid nonunions on the basis of union rates, functional outcomes, and operative complications...

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...

Isolated scaphoid dislocations are extremely rare injuries and are commonly associated with significant ligamentous disruptions. A dorsiflexion-supination force upon the hand is considered as the most common mechanism of injury. Different treatment options have been proposed for the management of this uncommon entity, ranging from conservative treatment with closed reduction and casting to a wide range of open or percutaneous surgical techniques. In this article, we reported ona case of this rare injury managed with open reduction and pinning along with ligamentous reconstruction...

We performed a cadaveric study to evaluate radiological performance of a technique for scapholunate intercarpal ligamentoplasty designed for treating reducible scapholunate dissociation. We created scapholunate instability in 12 fresh adult cadaveric forearms by sectioning the dorsal scapholunate interosseous ligament and the dorsal intercarpal ligament. All wrists showed scapholunate diastasis, dorsal intercalated segmental instability and posterior scaphoid subluxation. We performed scapholunate intercarpal ligamentoplasty in six wrists and Garcia-Elias three-ligament tenodesis in another six...

Chronic scapholunate ligament (SL) injuries are difficult to treat and can lead to wrist dysfunction. Whilst several tendon reconstruction techniques have been employed in the management of SL instability, SL gap reappearance after surgery has been reported. Using a finite element model and cadaveric study data, we investigated the performance of the Corella, scapholunate axis (SLAM) and modified Brunelli tenodesis (MBT) techniques. Scapholunate dorsal and volar gap and angle were obtained following virtual surgery undertaken using each of the three reconstruction methods with the wrist positioned in flexion, extension, ulnar deviation and radial deviation, in addition to the ulnar-deviated clenched fist and neutral positions...
