Diagnostics (Basel) 2024; 14:1177. [PMID: 38893703 PMCID: PMC11172194 DOI: 10.3390/diagnostics14111177] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2024] [Revised: 05/30/2024] [Accepted: 05/31/2024] [Indexed: 06/21/2024] Open
Abstract
INTRODUCTION The scapholunate interosseous ligament is pivotal for wrist stability, and its impairment can result in instability and joint degeneration. This study explores the application of real-time MRI for dynamic assessment of the scapholunate joint during wrist motion with the objective of determining its diagnostic value in efficacy in contrast to static imaging modalities. MATERIALS AND METHODS Ten healthy participants underwent real-time MRI scans during wrist ab/adduction and fist-clenching maneuvers. Measurements were obtained at proximal, medial, and distal landmarks on both dynamic and static images with statistical analyses conducted to evaluate the reliability of measurements at each landmark and the concordance between dynamic measurements and established static images. Additionally, inter- and intraobserver variabilities were evaluated. RESULTS Measurements of the medial landmarks demonstrated the closest agreement with static images and exhibited the least scatter. Distal landmark measurements showed a similar level of agreement but with increased scatter. Proximal landmark measurements displayed substantial deviation, which was accompanied by an even greater degree of scatter. Although no significant differences were observed between the ab/adduction and fist-clenching maneuvers, both inter- and intraobserver variabilities were significant across all measurements. CONCLUSIONS This study highlights the potential of real-time MRI in the dynamic assessment of the scapholunate joint particularly at the medial landmark. Despite promising results, challenges such as measurement variability need to be addressed. Standardization and integration with advanced image processing methods could significantly enhance the accuracy and reliability of real-time MRI, paving the way for its clinical implementation in dynamic wrist imaging studies.

Abstract
Ulnar-sided wrist pain can be a diagnostic challenge for clinicians and radiologists. The ulnar wrist has complex morphology and is composed of many small bone and soft tissue structures. Within these structures, a wide variety of pathologic conditions can occur. To successfully diagnose and treat these pathologic conditions, clinicians and radiologists must have a strong understanding of the advanced imaging techniques available to them. In this review, the authors present a brief review of the normal ulnar wrist anatomy, discuss the differential diagnosis of ulnar-sided wrist pain, and examine the indications for different advanced imaging modalities.

Abstract
INTRODUCTION Ganglion cysts represent the most common benign soft-tissue masses of the hand and wrist, most are treated nonoperatively, with relatively few local recurrences. Few studies have identified risk factors for recurrence in the pediatric population. The aim of this study is to identify risks of cyst recurrence and to establish if ultrasonographic imaging aids in the prediction of recurrence. METHODS A single-center retrospective chart review was performed, identifying patients diagnosed with a ganglion cyst of the hand or wrist. Demographic information, cyst characteristics, and ultrasound examination reports were documented. Standard statistical and logistic regression analyses were performed. RESULTS A total of 132 cysts were identified in 126 patients and the average age was 8.5 years old. The most common location was the dorsal wrist (57/132, 43.2%). There were 14 recurrences [11/14, (79%) dorsal wrist, 3/14 (21%) volar wrist, 0/14 (0%) in nonwrist locations]. The risk of recurrence was significantly greater for dorsal wrist cysts than nonwrist locations (odds ratio=18.1; 95% confidence interval: 1.02, 316.65; P=0.048); there was no statistical difference in recurrence rates between dorsal and volar cysts (P=0.15). Recurrence was noted in older patients (12.2 vs. 8.1 y, P<0.001) and those patients with painful masses (P=0.02). Patients undergoing surgical excision had a higher risk of recurrence than those who did not undergo surgical excision (P<0.001). Cyst volume as measured by ultrasound was performed in 37 cysts, with repeat ultrasounds in 12 cases demonstrating a decreased volume of 0.85 cm at baseline to 0.35 cm with repeat examination (P=0.40). In patients that received at least 1 ultrasound, there were no differences in cyst volume between those that recurred and those that did not (P=0.40). CONCLUSIONS Risk factors for recurrence in pediatric patients with a ganglion cyst include older age, symptomatic masses, cysts located around the wrist, and those requiring surgical excision. Ultrasound examination of cyst volume did not predict recurrence. LEVEL OF EVIDENCE Level III-therapeutic.

Abstract
Many anatomical details and variants occur in the finger tendons and soft tissue structures. These may lead to misdiagnosis if the radiologist is not well aware of them. We discuss the midhand extensor tendons, dorsal hood, junctura tendinea, conjoint tendons, transverse retinacular ligament, triangular ligament as well as central and distal slip anatomy and ultrasound correlation. The dorsal hood is an important structure to center the tendons at the midportion of the MCP heads, and the sagittal bands are its main components. Two tendons are present at the second digit, and two or more at the fifth digit. The extensor mechanism is anatomically interrelated with the palmar lumbricals and interosseous tendons. At the palmar side, the flexor superficialis and profundus tendons show varying relationships along the finger. The flexor profundus passes through an opening in the flexor superficialis. We also discuss the chiasma crurale, ridges at the flexor superficialis insertions and bifid flexor profundus tendon. Although a typical distribution of annular pulleys can be observed, many variants may be present of which we address some. The volar plate is a midline fibro-cartilaginous meniscus attached proximally to the well-identifiable checkrein ligaments and distally to the base of the phalanges. Knowledge of these details and variations allows for better understanding of the finger and hand ultrasound.

Abstract
Ultrasonography is a commonly utilized tool in orthopedic surgery for the diagnosis and treatment of a variety of musculoskeletal conditions, including pathology about the wrist. Its value should not be underestimated when other diagnostic resources are unavailable - such as in a combat setting where ultrasounds, but not X-ray, are a standard equipment item. An active duty soldier presented to an orthopedic provider in an austere environment with chronic dorsal wrist pain due to a previous fall. Physical examination and dynamic ultrasound examination allowed the deployed provider to diagnose a scapholunate ligament injury. The patient was appropriately evacuated to a higher level of care without the need for X-ray or other advanced imaging modalities. Making this readily available resource a standard tool for providers deployed to a forward location could be beneficial for efficient and appropriate patient evacuation for musculoskeletal injuries. It can also rule out injuries that would otherwise have required unnecessary soldier movement through hostile territory for diagnostic tests such as X-rays. In addition, a simple technique and pearls for ultrasonography of the wrist are provided.

Abstract
Determining the etiology of ulnar-sided wrist pain is often challenging. The condition may be acute or chronic, and differential diagnoses include injuries to the ulnar carpal bones, ligament tears, tendinitis, vascular conditions, osteoarthritis and systemic arthritis, and ulnar nerve compression. An anatomically based, methodical physical examination coupled with provocative maneuvers, including piano key, ulnar impaction, shuck, foveal stress, and extensor carpi ulnaris synergy tests, further defines the differential diagnosis. Diagnostic imaging used in the evaluation of ulnar-sided wrist pain includes plain radiographs and MRI with or without arthrography. Wrist arthroscopy is becoming increasingly important in the diagnosis and management of ulnar-sided intra-articular wrist pathology.
