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...

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...

Although isolated distal radius and scaphoid fractures are common, the combination of both fractures is rare, with a reported frequency between 0.5% and 6%. This rarity is probably due to the fact that both fractures share the same injury mechanism. Published studies are limited, but most patients are males in their 40s and the injuries are typically due to high-energy trauma. In most studies, the distal radius fracture is displaced while the scaphoid fracture is not. Since the functional outcome depends of the severity of the radius fracture, we believe, as do others, that it is logical to fix both fractures with stable devices (i...

Scapholunate advance collapse (SLAC) and Scaphoid nonunion advance collapse (SNAC), are the two most common patterns of postraumatic wrist arthritis. SLAC wrist develops after attenuation, either traumatically or atraumatically, of the scapholunate ligament. Atraumatic causes of SLAC wrist include calcium pyrophosphate dehydrate deposition disease, reumathoid arthritis, neuropathic diseases, and b2-microglobulin asociated amyloid deposition diseases. On the other hand, SNAC wrist develops following a scahpoid fracture that has progressed to a nonunion...

BACKGROUND: The I-Space is a radiological imaging system in which Computed Tomography (CT)-scans can be evaluated as a three dimensional hologram. The aim of this study is to analyze the value of virtual reality (I-Space) in diagnosing acute occult scaphoid fractures. METHODS: A convenient cohort of 24 patients with a CT-scan from prior studies, without a scaphoid fracture on radiograph, yet high clinical suspicion of a fracture, were included in this study. CT-scans were evaluated in the I-Space by 7 observers of which 3 observers assessed the scans in the I-Space twice...

PURPOSE: Scaphoid nonunion can occur in both non-operative and operatively treated scaphoid fractures. Without treatment, this can lead to a predictable pattern of carpal collapse and degenerative arthritic change and patients can experience both pain and functional loss in the early and late phases of progression. An operative technique with a high success rate for union is important. This paper describes a technique for treatment of scaphoid nonunion with K-wire fixation and iliac crest cancellous bone graft...

Scaphoid fracture is the most common carpal fracture of the upper extremity and a significant proportion of these can eventually progress to nonunion. Excision of pseudoarthrosis and fibrous scar tissue at the nonunion site is regarded as one of the important steps in management of scaphoid nonunions. We describe a technique of internal bone grafting, where curettage of the nonunion site was performed through a drill hole in the scaphoid and bone graft was packed through this same hole before fixation with a headless compression screw...

Kienböck disease is a condition that typically occurs in the "at-risk" patient, in the "at-risk" aspect of the proximal condyle of the "at-risk" lunate. In the active male, repetitive loading causes the stress fracture that commences in the single layer proximal subchondral bone plate. The lunate fracture commences at the point the lunate cantilevers over the edge of the distal radius, and then takes on the shape of the radius. We postulate that the stress fracture violates the parallel veins of the venous subarticular plexus-leading to localized venous hypertension and subsequent ischemia and edema of the fatty marrow...

We report the case of a 15-year-old boy with combined fractures of the scaphoid, capitate, and hamate that represents a rare variation of the well-known Fenton's syndrome. Fixation was performed for the unstable fractures of the scaphoid and capitate with the use of cannulated Herbert screws and K‑wires respectively. K‑wires were removed after 6 months, with subsequent physiotherapy. After 6 months, CT confirmed complete consolidation of the two surgically treated carpal fractures and the conservatively treated fracture of the hamate...
