Osteosynthesis with headless compression screws is an established treatment option for unstable scaphoid fractures. Common implants are made of titanium alloy or steel and usually remain in place. Due to implant density and ferromagnetic properties, artefacts are common in postoperative imaging procedures, e.g. MRI. Now resorbable implants made of magnesium alloy (MgYREZr) have become available. They have biomechanical properties equivalent to human bone and may be used as an alternative to the nonresorbable screw systems...

BACKGROUND: Studies of hardware protrusion into joint spaces following fracture fixation have been performed to address whether or not there is discrepancy between the actual and radiographic appearance of screw prominence. The purpose of our study was to prove that, with respect to the scaphoid, prominence as visualized on CT scan is real and not a result of metal artifact. METHODS: Forty-two cadaveric wrists were separated into four allotted groups with 21 control specimens and 21 study specimens...

Scaphoid fractures are the most common carpal fractures. Percutaneous fixation is a popular treatment option for nondisplaced or minimally displaced scaphoid fractures. Placement of the guidewire in the percutaneous fixation procedure often requires several attempts and adjustments with the help of intraoperative fluoroscopy. This article describes a 1-shot procedure of percutaneous fixation for acute scaphoid fracture with patient-specific guiding templates made by computer reconstructions and 3-dimensional printing technique...

Basel A Khader, Mark R Towler
The distal radius and the scaphoid are the most commonly injured carpal bones among both active adults and the osteoporotic elderly. The purpose of surgical treatment is to restore form and function to the wrist. Depending on the nature of the fracture, either topical procedures or invasive surgery can be applied. This article critiques the treatments currently used for fixation of wrist fractures in order to drive the development of new materials to improve patient outcomes.

REVIEW
Mark J Winston, Andrew J Weiland
Scaphoid fractures are a common wrist injury, especially in athletes. Clinicians should have a high index of suspicion for a scaphoid fracture in any patient complaining of radial-sided wrist pain after a fall on an outstretched hand. Advanced imaging, including CT and MRI scans, may be useful in diagnosis and classification of fracture patterns. Treatment varies based on the fracture location, stability of the fracture, and predictability of the fracture to heal. Treatment involves either non-operative management with a thumb spica cast or brace, or operative fixation with a headless compression screw, k-wires, or scaphoid-specific plates...

PURPOSE: Achieving stable fixation of scaphoid fractures and nonunions continues to be a challenge. Compression screw fixation has been the current standard surgical procedure. However, in some cases, bone healing cannot be achieved and requires further revision. Recent series reintroduced volar plating as valid option for stable fixation. The aim of the study was to review clinical outcome of alternative scaphoid treatment. METHODS: From 2011 to 2014, nine patients with scaphoid fracture were treated by Headless Compression Screw (HCS) and seven patients with scaphoid nonunion by HCS or volar mini condylar plate with bone graft...

Introduction. Scaphotrapezial synostosis has been rarely reported in the literature and only one case underwent surgical treatment for scaphoid fracture. Presentation of Case. A 15-year-old male presented with a painful left wrist following a fall. The initial radiographs showed a displaced scaphoid proximal pole fracture and a Scaphotrapezial synostosis. The fracture was then fixed percutaneously with satisfactory outcome. Discussion. Scaphotrapezial synostoses are very rare and most found in patients with multiple congenital anomalies or as part of a hereditary syndrome...

BACKGROUND: Sometimes patients with a scaphoid fracture, especially in an acute phase of injury, can have normal radiographs and, therefore, initial diagnosis of the scaphoid fracture may be neglected. In this study, we determined the value in of clinical examination and a radiograph in the diagnosis of scaphoid fracture based on the results of a two-week follow-up magnetic resonance imaging (MRI). OBJECTIVES: In this study, sought to assess the value of using both a clinical examination (tenderness of scaphoid tubercle, tenderness of anatomical snuffbox, and compression test) and radiographic imaging in the diagnosis of scaphoid fractures based on the results after a two-week follow-up MRI...

A 13-yr-old adolescent boy presented with wrist pain after falling off a scooter onto his outstretched hand. Radiographs revealed a nondisplaced hairline fracture of the scaphoid bone and an irregular radiolucent line in the proximal metaphysis of the second metacarpal bone, consistent with an anomalous growth plate, or complete pseudoepiphysis. Complete pseudoepiphysis is a rare finding, with only a few cases reported. Learning about the common locations of growth plates and the radiographic differences between normal, injured, and anomalous growth plates can help decrease physician error and improve patient outcomes...

Background: Fractures of the proximal pole of the scaphoid can be difficult to heal because of its limited vascular supply. Furthermore, nonunion with avascular necrosis and secondary fragmentation makes surgical reconstruction a challenging procedure. Method: We describe a technique and report the outcome of a proximal hamate autograft to treat a proximal pole scaphoid nonunion with avascular necrosis. Results: At 3.5 years post reconstruction, the patient remains asymptomatic with union of his scaphoid reconstruction without any evidence of scapholunate instability...

Scaphoid fractures are common injuries which traditionally have been treated with long periods of immobilization even after open reduction and internal fixation (ORIF). The purpose of this pilot investigation was two-fold: 1) describe a precise postoperative Early Active Motion (EAM) rehabilitation protocol following ORIF of scaphoid fractures and 2) record the outcomes of the EAM protocol. Eight consecutive patients having undergone ORIF of the scaphoid were enrolled in the EAM and followed for a minimum of 1 year...

BACKGROUND: Our goal was to analyze the movement of acute scaphoid waist fracture fragments and adjacent bones in a common coordinate system. Our hypothesis was that the distal scaphoid fragment flexes and pronates and the proximal fragment extends. METHODS: Computed tomography (CT) scans of patients diagnosed with an acute scaphoid waist fracture were evaluated using a 3-dimensional (3D) model. The scans of 57 nondisplaced and 23 displaced fractures were compared with a control group of 27 scans showing no pathological involvement of the wrist...

INTRODUCTION: Perilunate dislocations are commonly seen after fall on an outstretched hand in extremes of dorsiflexion and ulnar deviation. A greater arc injury is one when there is an associated fracture of one or more bones around the lunate while a lesser arc injury is associated with pure ligamentous disruption around the lunate. CASE REPORT: We report a unique case of bilateral trans-scaphoid perilunate dislocation in a 35-year-old male labourer. This is the first reported case where the lunate dislocated into the forearm on the volar aspect...

Surgical treatment of scaphoid nonunion is not always successful, often requiring stabilization and bone grafting to achieve healing. Even after intramedullary screw fixation, residual instability may still hinder union. The purpose of this study was to describe the addition of Kirschner wires (KWs) through the capitate and the lunate to supplement an intramedullary screw for temporary enhanced stability, possibly improving healing of unstable fractures. A case-control study reviewing 25 cases with addition of KWs and 19 controls was performed...

Scaphoid fractures constitute 71% of all carpal bone fractures.(1) Early diagnosis and treatment has significant bearing on fracture union rates and better clinical outcomes. While displaced fractures can be readily seen on plain radiograph, undisplaced fractures can require advanced imaging modalities to confirm that diagnosis. Advanced imaging such as Magnetic Resonance Imaging (MRI), Computerised tomography (CT) and bone scintigraphy are routinely used for the diagnosis of scaphoid fractures but require significant radiation exposure, increased cost and can be difficult to access...

Introduction Fracture of the scaphoid bone is the most common fracture of the carpus. However, the fracture union occurs late or may not heal. Sometimes, fracture healing requires prolong immobilization. Because of potential for joint stiffness, muscle atrophy, or the inability to use the hand during and after prolonged immobilization, there is great incentive to develop therapies that will accelerate bone healing and allow a quick return to work. To date, the effect of platelet-rich plasma (PRP) on scaphoid fracture has not been studied...

PURPOSE: Scaphoid fracture commonly occurs around the mid-third of the scaphoid, and non-union of this fracture has several treatment options. The authors performed autologous cancellous bone graft from the iliac crest and headless compression screw fixation for the treatment of Mack-Lichtman type II scaphoid waist non-union. The purpose of this study was to determine whether this procedure was effective in achieving bony union and restoration of alignment. METHODS: Medical records and radiographs of 30 patients who underwent cancellous bone graft and headless compression screw fixation for non-union of scaphoid waist fracture were retrospectively reviewed...

We analysed scaphoid deformity as a result of surgical treatment of scaphoid fracture nonunion and assessed the deformity associated with a dorsal intercalated segmental instability pattern of carpal malalignment. A total of 45 patients who were treated for scaphoid fracture nonunion were included in the study. The height-to-length ratio of the scaphoid was measured on computed tomographic images and used to assess scaphoid deformity. Carpal malalignment was quantified based on the radio-lunate angle. A correlation analysis between the height-to-length ratio and the radio-lunate angle was performed...

In this literature review, the authors analyse the prognostic factors in the curative treatment of scaphoid non-unions. The main negative prognostic factors are smoking, the time elapsed since the fracture, and avascular necrosis of the proximal fragment. If the latter is present, the revascularization by a pedicle or microsurgical bone autograft is probably the treatment of choice. In non-unions without evidence of osteonecrosis, vascularized bone grafts are probably not superior to conventional bone grafts, which can presently be performed under arthroscopic control, with minimal morbidity...
