The patient complains of snapping and locking of finger like a trigger as the gliding of the flexor tendon become harder through the thickened pulley during flexion and superadded development of nodule on the surface of the tendon proximal to pulley. In severe cases or failed conservative/steroid injection cases, real-time percutaneous release of pulley under ultrasound (US) guidance can be considered. The percutaneous pulley release is a minimally invasive procedure compared to open surgical release and more accurate than blind percutaneous release with overall minimal complications. The US-guided percutaneous A1 pulley release has been described in the literature and done by knife, straight needles, and acutely bent needles with variable results. We describe the curved needle technique of percutaneous pulley release. The curved needle technique for US-guided A1 pulley release is novel and has the advantage of easy maneuverability over acutely bent needle and minimal chances of complications. The cutting edge of the curved needle scores through the thickened pulley with effective release and easy maneuverability.","PeriodicalId":38088,"journal":{"name":"Journal of Arthroscopy and Joint Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48939650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MRI is a careful interplay between the temporal, spatial, and contrast resolution which forms the foundation for its improved diagnostic performance and value. There are a lot of aspects that improve the image quality and diagnostic performance, however, a higher magnet strength of 3-Tesla has the biggest impact within the current diagnostic range. However various advancements in the hardware and software parameters such as multichannel multi-phased array coils, advanced gradient systems and better post processing techniques have significantly improved image quality at 1.5T scanners as well. All the leading manufacturers offer MRI systems with a higher field strength of 3T which are increasingly being used in recent clinical settings. Scanning at 3T has the advantage of a better signal-to-noise ratio which translates into better spatial and temporal resolution with the added advantage of faster acquisition. Challenges of 3T scanning include higher magnetic susceptibility, chemical shift, and higher radiofrequency energy deposition. This is particularly important in the presence of orthopedic implants because of the two-fold increase in susceptibility artifacts resulting in significant periprosthetic signal loss, signal displacements with voids and pileups, and failed spectral fat suppression. Various modifications are needed to minimize the artifacts at 3T scanners to better utilize the improved spatial and contrast resolution achieved as a result of scanning at a higher field strength. This review discusses the technical features of scanning at 1.5 and 3T scanners along with their clinical implications and diagnostic usefulness in MSK imaging.","PeriodicalId":38088,"journal":{"name":"Journal of Arthroscopy and Joint Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46112048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different intraoperative modalities have applications in the diagnosis, treatment, and monitoring of patient affected by various medical or surgical conditions. Advances in technology, computer software, and integration of various radiological modalities have extended the applications of intraoperative imaging in health care. Intraoperative radiological imaging have evolved from the initial use of conventional fluoroscopy to current innovations of computed tomography (CT) such as three-dimensional cone-beam CT and magnetic resonance-based imaging. In fact, intraoperative imaging has become integral to most of trauma and orthopedic procedures. Apart from their role in diagnosis of a spectrum of orthopedic conditions like prosthetic joint infection, imaging systems assist orthopedic surgeons to perform minimally invasive procedures, improving patient safety and also enabling higher accuracy and lower revision rates. More importantly, advances in technologies are essential in safeguarding radiation safety regulations, thereby reducing the radiation dose to the patient and surgical team. Integration of various imaging technologies, improving quality of image acquisition, reduction of radiation dose, and seamless image transfer to allow decision-making process are crucial in the delivery of effective patient care.","PeriodicalId":38088,"journal":{"name":"Journal of Arthroscopy and Joint Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135357854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
