scaphoid fracture

PURPOSE: To study the clinical, radiological, and functional outcomes after of radioscapholunate (RSL) fusion for intra-articular malunion of the distal radius. METHODS: This retrospective study included 26 patients (17 males and 9 females) with intra-articular malunion of distal radius fractures who underwent RSL arthrodesis using locked miniplates (without distal scaphoid excision) between 2012 and 2020. Their mean age was 43 years (range, 32-56). Patients were assessed radiographically for union and clinically for range of motion, grip strength, and pain (assessed by Visual Analogue Scale (VAS) for pain)...

AIMS: The underlying natural history of suspected scaphoid fractures (SSFs) is unclear and assumed poor. There is an urgent requirement to develop the literature around SSFs to quantify the actual prevalence of intervention following SSF. Defining the risk of intervention following SSF may influence the need for widespread surveillance and screening of SSF injuries, and could influence medicolegal actions around missed scaphoid fractures. METHODS: Data on SSF were retrospectively gathered from virtual fracture clinics (VFCs) across a large Scottish Health Board over a four-year period, from 1 January 2018 to 31 December 2021...

Objective This study evaluated the epidemiological data and functional outcomes from patients with concomitant distal radial and scaphoid fractures treated in a single center specialized in hand surgery. Functional outcomes analysis used validated instruments. Methods  Patients diagnosed with distal radial and scaphoid fractures treated from January 2011 to December 2021 underwent assessments using the Disabilities of the Arm, Shoulder and Hand (DASH), Patient-Rated Wrist Evaluation (PRWE), Visual Analog Scale (VAS) for pain, goniometry, radiographic consolidation, and complications six months after surgery...

This case report is about a patient with self-induced hot water burns several hours after an infraclavicular block with ropivacaine for a scaphoid fracture operation. This patient was honest about what happened. However, some patients are too embarrassed to admit what they did to themselves. The injury may be misdiagnosed by the emergency department physician or by the surgeon because the history is incomplete. The resulting burn, which can lead to fingertip loss when severe, can be erroneously misdiagnosed as an ischemic injury after lidocaine with epinephrine local anesthesia...

Distal radius fractures are the most common fractures in adults and account for one quarter of all fractures, with increasing incidence. The number of patients and the requirement of an exact treatment are high. Continuous developments in diagnostic and operative possibilities enable in many cases a high-quality treatment with good clinical outcome; however, radius fractures rarely occur alone but in combination with additional fractures or ligamentous injuries. The frequency and extent of these injuries are not linked to the complexity of the primary injury...

AIMS: There is a lack of published evidence relating to the rate of nonunion seen in occult scaphoid fractures, diagnosed only after MRI. This study reports the rate of delayed union and nonunion in a cohort of patients with MRI-detected acute scaphoid fractures. METHODS: This multicentre cohort study at eight centres in the UK included all patients with an acute scaphoid fracture diagnosed on MRI having presented acutely following wrist trauma with normal radiographs...

PURPOSE: To review the existing literature to (1) determine the diagnostic efficacy of artificial intelligence (AI) models for detecting scaphoid and distal radius fractures and (2) compare the efficacy to human clinical experts. METHODS: PubMed, OVID/Medline, and Cochrane libraries were queried for studies investigating the development, validation, and analysis of AI for the detection of scaphoid or distal radius fractures. Data regarding study design, AI model development and architecture, prediction accuracy/area under the receiver operator characteristic curve (AUROC), and imaging modalities were recorded...

Perilunate dislocations are uncommon high energy injuries. The combination of fractures resulting in a trans-styloid, trans-scaphoid, and trans-triquetral perilunate fracture dislocation is extremely rare. We describe a 20 year old male who suffered this injury after a fall from height while parkouring. He underwent open reduction and internal fixation with ligamentous repair and carpal tunnel decompression. After 3 months, he was noted to have a radiographic evidence of scapholunate dissociation and he returned to the operative room for definitive fixation...

BACKGROUND: Scaphoid fractures are less commonly reported in adults older than 50 years. The association between bone density and outcomes following scaphoid fractures has not been explored in this patient population. The second metacarpal cortical percentage (2MCP) has been shown to predict low bone density. The purpose of this study is to describe the epidemiology and radiographic characteristics associated with scaphoid fractures in adults older than 50 years, determine the prevalence of osteopenia defined by 2MCP, and evaluate the characteristics associated with scaphoid nonunion in this population...

BACKGROUND: The scaphoid is an important mechanical stabilizer for both the proximal and distal carpal columns. The precise estimation of the complete scaphoid bone based on partial bone geometric information is a crucial factor in the effective management of scaphoid nonunion. Statistical shape model (SSM) could be utilized to predict the complete scaphoid shape based on the defective scaphoid. However, traditional principal component analysis (PCA) based SSM is limited by its linearity and the inability to adjust the number of modes used for prediction...

Background: The most common types of wrist dislocation are trans-scaphoid lunate dislocation (TLD) and trans-scaphoid perilunate dislocation, in which the lunate and proximal scaphoid are dislocated through the midcarpal joint. There is another rare type of dislocation in which the proximal carpi are dislocated through the radiocarpal joint. The purpose of this study is to examine the clinical features of this type of dislocation. Methods: Six cases of the proximal carpal fracture dislocation via the radiocarpal joint were retrospectively reviewed...

BACKGROUND Scaphocapitate syndrome is a rare clinical entity consisting of a combined scaphoid and capitate fracture along with a 90- or 180-degrees rotation of the proximal capitate fragment. The syndrome is scarcely described in the literature, with proximal migration of the capitate fragment being reported only by Mudgal et al in 1995. Concurrent compression of the median nerve is a highly unfortunate event, suggesting a unique case presented here. CASE REPORT We present a unique case of scaphocapitate fracture-dislocation in a 25-year-old man with volar dislocation of the capitate's fragment deep to the median nerve...

The objective of this study was to assess the downsides of surgical treatment of scaphoid fracture nonunion in patients with minor preoperative symptoms. Patients were classified with minor symptoms based on the Patient-Rated Hand/Wrist Evaluation questionnaire. Of the 35 included patients, most patients encountered problems with patient-specific activities; 9% reported worse postoperative functional outcomes, 34% were not satisfied with the treatment and 9% were reoperated. The risk of a worse functional outcome after surgery with the need for further operations and the chance of developing wrist osteoarthritis, along with the possibility of poor patient satisfaction and ongoing daily functional impairment, should be considered during preoperative counselling...

In vivo high-resolution peripheral quantitative computed tomography (HR-pQCT) studies on bone characteristics are limited, partly due to the lack of standardized and objective techniques to describe motion artifacts responsible for lower-quality images. This study investigates the ability of such deep-learning techniques to assess image quality in HR-pQCT datasets of human scaphoids. In total, 1451 stacks of 482 scaphoid images from 53 patients, each with up to six follow-ups within one year, and each with one non-displaced fractured and one contralateral intact scaphoid, were independently graded by three observers using a visual grading scale for motion artifacts...

Background The medium-term outcomes of patients (six to 14 months post-injury) with non-specific wrist injuries managed as suspected scaphoid fractures are not clear from the current literature. These patients' wrists are immobilized in casts or splints, and some receive physiotherapy. They receive serial imaging and follow-up appointments as needed. Aims This study aims to describe the medium-term outcomes of patients with non-specific wrist injuries managed as suspected scaphoid fractures. Methods This is a single-centre retrospective cohort study...

BACKGROUND: The scaphoid is the most commonly fractured carpal bone in children. True scaphoid fractures have proven to be difficult to diagnose, as they may not be apparent on initial imaging. Children with clinical suspicion of a scaphoid fracture may be treated with continued immobilization, even in the absence of radiographic evidence of a fracture. The purpose of this study is to identify predictors of true scaphoid fractures in children to help guide management. METHODS: This study is a retrospective cohort study of children presenting to a tertiary pediatric hospital with hand or wrist injuries...

PURPOSE: Scaphoid fractures in patients and assessment of healing using PCD-CT have, as far as we know, not yet been studied. Therefore, the aim was to compare photon counting Detector CT (PCD-CT) with energy integrating detector CT (EID-CT) in terms of fracture visibility and evaluation of fracture healing. METHOD: Eight patients with scaphoid fracture were examined with EID-CT and PCD-CT within the first week post-trauma, and with additional scans at 4, 6 and 8 weeks...

We present an unusual case involving the simultaneous dislocation of the trans-scapho-retro-lunate in the right wrist and a posterolateral dislocation in the right elbow joint with a distal radius fracture in a 23-year-old male with no notable medical history. These injuries occurred when he fell from a height of around 12 meters onto his outstretched right hand. The patient presented to the hospital in a normal upper limb trauma position with no discomfort to critical functions. Predominant symptoms at the emergency department were discomfort in the right wrist, hand, and ipsilateral elbow, as well as the entire upper limb functional impairment...

To assess factors related to health-system and patient behavior in scaphoid fracture non-union, a retrospective analysis of 134 patients treated by scaphoid reconstruction was performed. Mean age at the accident was 26 years (range, 9-75 years), and the mean age at surgery was 28 years (range, 13-75 years). Mean time to first consultation was 233 days (range, 0-12,136 days), and time to surgery 740 days (range, 19-12,362 days). The physician was mainly a general practitioner (52.2%), or an orthopedist/traumatologist (17...
