Osteomyelitis of the carpal bones is rare and usually occurs in the setting of penetrating wounds or immune compromise. A case of hardware-associated scaphoid osteomyelitis is reported in a 33-year-old man who underwent screw fixation of a scaphoid fracture more than 20 years prior to presentation. The patient was treated with operative debridement including a total scaphoidectomy as well as intravenous antibiotics. Methicillin-sensitive Staphylococcus aureus was isolated from intraoperative cultures. A secondary proximal row carpectomy was performed to provide a stable wrist...

BACKGROUND: Cystic lesions of the carpal bones are rare entities that are infrequently reported in the literature. Scaphoid intraosseous cystic lesions represent a rare subset of carpal bone cysts. This review aims to summarize the available evidence on the evaluation and treatment of scaphoid cystic lesions to help guide clinical management. METHODS: Systematic electronic searches were performed using PubMed, Ovid, and Embase databases. Studies included were graded for their risk of bias...

OBJECTIVE: To systematically review the literature on the performance of ultrasound in diagnosing radiographically occult scaphoid fracture. METHODS: A systematic search was performed in the MEDLINE and Embase databases. Original studies investigating the performance of ultrasound in diagnosing radiographically occult scaphoid fracture in more than 10 patients were eligible for inclusion. Studies that included both radiographically apparent and occult scaphoid fractures (at initial radiography) were only included if independent data on radiographically occult fractures were reported...

BACKGROUND: Current techniques for fixation of proximal pole scaphoid fractures utilize antegrade fixation via a dorsal approach endangering the delicate vascular supply of the dorsal scaphoid. Volar and dorsal approaches demonstrate equivalent clinical outcomes in scaphoid wrist fractures, but no study has evaluated the biomechanical strength for fractures of the proximal pole. This study compares biomechanical strength of antegrade and retrograde fixation for fractures of the proximal pole of the scaphoid...

INTRODUCTION: We report the outcome of using a novel technique of minimally invasive internal fixation and distal radius bone grafting using the Jamishidi Trephine needle and biopsy/graft capture device. METHODS: The technique utilises a 8 mm incision at the distal pole of the scaphoid. The non-union is excavated using the standard Acutrak drill. An 8 gauge Jamshidi trephine needle is used to harvest bone graft from the distal radius which is impacted into the scaphoid and fixed with an Acutrak screw...

Background  An injury to the scapholunate interosseous ligament (SLIL) leads to instability in the scapholunate joint. Temporary fixation is used to protect the ligament during reconstruction or healing of the repair. Rigid screw fixation-by blocking relative physiological motion between the scaphoid and lunate-can lead to screw loosening, pullout, and fracture. Purpose  This study aims to evaluate changes in scaphoid and lunate kinematics following SLIL injury and the effectiveness of an articulating screw at restoring preinjury motion...

Scaphoid nonunion causes abnormal wrist kinematics and typically leads to carpal collapse and subsequent degenerative arthritis of the wrist. However, the natural history, including carpal collapse and degenerative arthritis of scaphoid nonunion, may vary at different fracture locations. This article reviews recent biomechanical studies related to the natural history of scaphoid nonunion. In the distal-type fractures (type B2 in Herbert classification), where the fracture located distal to the scaphoid apex, the proximal scaphoid fragment and lunate, which are connected through the dorsal scapholunate interosseous ligament (DSLIL) and dorsal intercarpal ligament (DIC), extend together, and the distal fragment of the scaphoid flexes individually...

Background: It is important to diagnose a scaphoid fracture accurately and start the correct treatment in the shortest time possible. However, the fracture of bone may not be visible on x-ray. In such cases, patients are clinically diagnosed with suspected or occult scaphoid fractures. The aim of this study was to define a scoring system based on physical examination to demonstrate the risk for bone injury in patients with clinically suspected and occult scaphoid fractures with negative radiographs and anatomical snuff box tenderness and to decrease the costs and workforce loss due to unnecessary treatment and magnetic resonance imaging (MRI)...

PURPOSE: Wrist has a complex anatomy and undergoes complex injuries. Scaphoid fracture is one of such injuries. It is the most common fracture in carpal bone. Most of the scaphoid fractures are missed on initial X-rays. Magnetic resonance imaging (MRI) is considered as a gold standard for diagnosing scaphoid fractures. Ultrasonography (USG) is emerging as a good alternative to make an early diagnosis of scaphoid fractures. Our aim is to throw light upon the role of USG in detection of scaphoid fractures...

OBJECTIVES: The purpose of this study is to determine the predictive value of clinical suspicion for scaphoid fracture in children aged 4 to 11 years, to look at the efficiency and practicality of current management of children presenting to the emergency department, and to help quantify the burden of the treatment strategy of immobilization for 10 to 14 days on clinical grounds despite negative or equivocal x-rays on presentation. METHODS: We performed a retrospective chart review study of a consecutive sample of all children aged 4 to 11 years old who presented to a tertiary pediatric emergency department from January 1, 2009, to December 31, 2013, within 24 hours of a wrist injury, with a clinical suspicion sufficient to order a scaphoid x-ray...

Scaphoid nonunions are challenging injuries to manage and the optimal treatment algorithm continues to be debated. Most scaphoid fractures heal when appropriately treated; however, when nonunions occur, they require acute treatment to prevent future complications like scaphoid nonunion advanced collapse. Acute nonunion treatment technique depends on nonunion location, vascular status of the proximal pole, fracture malalignment, and pre-existing evidence of arthrosis. Bone grafting and vascular grafts are common in nonunion management...

OBJECTIVES: Our primary aim was to evaluate the distribution and severity of cartilage damage in a sample of patients with scaphoid nonunion advanced collapse (SNAC), assessed on MDCT arthrography, with regard to two well-known SNAC staging systems. Secondarily, we wanted to see if the degree of cartilage damage varied with the location of the nonunion. METHODS: We retrospectively included 35 patients with a history of SNAC who had undergone MDCT arthrography. The location of the fracture was defined as the proximal, middle, or distal third of the scaphoid...

Background: Percutaneous screw fixation is widely used in acute fractures of the scaphoid. In this study, we aimed to present our results with volar percutaneous screw fixation in patients with scaphoid nonunions. Methodology: A total of 12 patients with scaphoid nonunion (≥13 weeks) that underwent volar percutaneous screw fixation were evaluated retrospectively. Two of the patients were female, and 10 were male. Mean age was 27 years (range = 19-41). The mean time that elapsed between the fracture and surgical procedure was 7...

BACKGROUND: The association of scaphoid or other carpal bone fractures with distal radius fractures is frequently reported, whereas few studies have described pisiform malalignment associated with distal radius fractures. The purpose of this study was to investigate the frequency and characteristics of pisiform malalignment associated with distal radius fractures. METHODS: We performed a retrospective study by reviewing the data of 152 consecutive patients with a mean age of 63 years who were treated surgically for distal radius fractures during a five-year period...

The aim of this study was to evaluate and compare the diagnostic accuracy, the inter-rater agreement and raters' certainty of cone beam computed tomography (CBCT) and radiography for the detection of scaphoid fractures. Our hypothesis is that the CBCT has a higher diagnostic accuracy for scaphoid fractures than radiography. We retrospectively analysed patients who underwent both radiography and CBCT examinations within 4 days to rule out a scaphoid fracture over a 2-year period in our institution. 4 blinded radiologists and orthopaedic surgeons independently rated the images regarding the presence of a scaphoid fracture...

The scaphoid is the most frequently fractured carpal bone and prone to non-union due to mechanical and biological factors. Whereas the importance of stability is well documented, the evaluation of biological activity is mostly limited to the assessment of vascularity. The purpose of this study was to select histological and immunocytochemical parameters that could be used to assess healing potential after scaphoid fractures and to correlate these findings with time intervals after fracture for the three parts of the scaphoid (distal, gap and proximal)...

REVIEW
Berthold Bickert
Complete rupture of the scapholunate (SL) ligament can cause a dissociative carpal instability (CID). These ligamentous lesions are caused by a fall from a limited height of approximately 1 m or a fall, e. g. when playing handball or soccer. For a freshly injured wrist joint, the X‑ray signs of a static instability (after excluding a fracture) are a SL distance ≥3 mm, a SL angle >60°, and a dorsal displacement of the proximal scaphoid pole. Dynamic instabilities are best seen in kinematography of the wrist joint...
