Scaphoid fractures are the most common type of carpal injuries that occur in children and adolescents. The injury pattern seen in children and adolescents who have scaphoid fractures has recently shifted to resemble that of adults who have scaphoid fractures, with scaphoid waist fractures being the most common injury pattern. This shift has been attributed to increased body mass index in children and adolescents as well as more intense participation in extreme sports by both children and adolescents. The diagnosis of scaphoid fractures is based on both a clinical examination and radiographic fi ndings...

The goal of wrist denervation is to decrease pain at the wrist, whether caused by an intra- or extra-articular problem or even when the reason for the pain is unknown. It is an alternative to partial or total arthrodesis and proximal row carpectomy. Our hypothesis was that wrist denervation with a two-incision technique was a reliable and efficient way to treat painful degenerative wrists. Thirty-three patients, 48years old on average, were included in this study. Indications were scapholunate advanced collapse (SLAC) in 18 cases, scaphoid nonunion advanced collapse (SNAC) in 10, distal radius fracture sequelae with advanced radiocarpal osteoarthritis in 4, and post-traumatic ulnocarpal impingement in 1 case...

Cortical bone grafting is commonly required in the finger, hand, and carpus when managing bony trauma. A donor site that can provide a small or large amount of cortical bone graft that is easily accessible and within the same surgical field would be the ideal donor site. In high-energy injuries, a long cortical graft may be needed to reconstruct massive bony defects. In low-energy injuries such as scaphoid nonunions in which a wedge graft is needed, a reliable and easily accessible source of bone grafting would be beneficial...

Background: Whether antenatal and neonatal vitamin D status have clinical relevance in fracture prevention has not been examined extensively, although observational studies indicate that fetal life may be a sensitive period in relation to bone growth and mineralization during childhood.Objective: We examined whether 25-hydroxyvitamin D3 [25(OH)D3] concentrations in stored neonatal dried blood spot (DBS) samples are associated with pediatric fracture risk. We hypothesized that in particular, low neonatal vitamin D status may be a risk factor for fracture incidence among children...

Treatment of nondisplaced scaphoid waist fractures has evolved from conventional cast immobilization to percutaneous screw insertion. This study assessed clinical and radiologic outcomes of volar percutaneous screw fixation for 15 type B2 scaphoid fractures (according to the Herbert and Fisher classification). All patients were followed for an average of 33 months (range, 6-50 months). All fractures achieved radiographic union at an average of 57 days (range, 35-70 days), requiring no additional procedures...

BACKGROUND: The purpose of this systematic review is to analyze the indications, outcomes, and complications of scaphoid fixation with a staple. METHODS: The literature was reviewed for all cases of the scaphoid staple. Five articles including 188 patients, of 77 primary scaphoid fractures and 111 other indications that included delayed union, nonunion, and avascular necrosis, were reviewed. Demographic data, outcomes, and complications were recorded. RESULTS: The union rate of the scaphoid staple is 94...

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...

Shoulder fracture-dislocations are uncommon. Those associated with intrathoracic dislocation are very rare conditions, resulting from high-energy trauma; usually, the affected limb is in an abduction position. In Brazil, there is only one report of a teenager with displacement of the epiphysis into the chest cavity; the present is the first adult patient report of intrathoracic dislocation of the humerus. The authors present the case of a patient female, aged 56 years, who was hit by motorcycle and thrown approximately 5 meters away...

BACKGROUND: Scaphoid fractures progress to nonunion rates of up to 15% when non-displaced, and are even more frequent when the fracture is displaced. Standard treatment in these cases is surgery; however, individuals unable to undergo this operation, or for those who wish to try more conservative measures, there may be benefit from nonoperative options. Of these, low-intensity pulsed ultrasound (LIPUS) has been shown to improve fracture nonunion healing. The purpose of this study was to perform a comprehensive meta-analysis of relevant literature to determine success of the use of LIPUS for treatment of scaphoid nonunion...

We investigated the effect of an interfragmentary gap on the final compression force using the Acutrak 2 Mini headless compression screw (length 26 mm) (Acumed, Hillsboro, OR, USA). Two blocks of solid rigid polyurethane foam in a custom jig were separated by spacers of varying thickness (1.0, 1.5, 2.0 and 2.5 mm) to simulate an interfragmentary gap. The spacers were removed before full insertion of the screw and the compression force was measured when the screw was buried 2 mm below the surface of the upper block...

INTRODUCTION: In treatment of scaphoid non-union bone healing requires beside vital tissue and stability, enduring compression and a good interface between the graft and scaphoid fragments. While fixation techniques show a good primary stability, they reduce sintering and thus compression of fragments in the long term. Therefore, a modified technique optimising the cancellous interface between graft and scaphoid but still providing enough stability without fixating implants should be evaluated...

PURPOSE: In nonsurgical treatment for acute undisplaced or minimally displaced scaphoid waist fractures, immobilization of both wrist and thumb can be an option. However, in vivo scaphoid motion during forearm and thumb motion with the wrist immobilized in a cast has not been measured. Therefore, we examined the in vivo kinematics of the scaphoid during forearm and thumb motion with cast immobilization. METHODS: Ten healthy right wrists of 10 male volunteers were included...

PURPOSE: The recommended technique for the fixation of a scaphoid waist fracture involves a headless compression screw placed in the proximal fragment center. This is usually accomplished by placing a longitudinal axis screw as visualized by fluoroscopy. The screw length has been shown to have a biomechanical advantage. An alternative to these options, which has been debated in the literature, is a screw placed perpendicular to the fracture plane and in its center. The perpendicular screw may have a biomechanical advantage despite the fact that it may be shorter...

Background: Perilunate fracture dislocations are often associated with fractures of the distal pole of the scaphoid or the proximal pole of the capitate. However, the combination of perilunate dislocation with multiple carpal fractures and associated scaphocapitate syndrome is very rare. Methods: We report a unique case of scaphocapitate fracture syndrome with perilunate dislocation and fracture of the hamate resulting from a high-energy injury to the wrist during a dirt-bike competition. Results: Open reduction and internal fixation of the scaphoid fracture with a 3...

Background: Radial head fractures can be associated with soft tissue injuries of the forearm and wrist. The Essex-Lopresti injury can lead to significant morbidity, especially if the diagnosis is not made acutely. Better identification of such injuries is needed to allow optimal surgical treatment and prevent long-term sequelae. We used magnetic resonance imaging (MRI) to correlate the degree of soft tissue injuries with radial head fractures. Methods: Sixteen pairs of forearms with an associated radial head fracture in 15 patients prospectively underwent an MRI within 2 weeks of their injury...

REVIEW
Ai Dong Deng, Marco Innocenti, Rohit Arora, Markus Gabl, Jin Bo Tang
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...

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...
