Use flex or head coil. It is an often-encountered injury and can lead to chronic pain and instability when diagnosed incorrectly. Our aim was to evaluate the utility of US in the acute setting.

The surgical findings of five Stener lesions and two complete ruptures of the UCL without a Stener lesion were correctly reviewed by both readers. Historically, routine radiography including stress views does not allow such diagnosis and is potentially detrimental to patient care. The Stener Lesion: Historical Perspective and Evolution of ... The close proximity of the APB tendon insertion with the RCL also can predispose an individual to the radial equivalent of a Stener lesion ( Fig 13 ). Injury to the ulnar collateral ligament (UCL) of the thumb requires imaging for diagnosis of surgically important entities such as the Stener lesion. At clinical examination there is inability of grasping activities between the thumb and the second digit and laxity with valgus stress.

US was performed by three experienced radiologists in 32 patients with a clinical suspicion of UCL injury. The initial imaging study to evaluate for a Stener lesion should be radiographs to assess for an osseous avulsion injury. This prospective case series compared the accuracy of ultrasound (US) to magnetic resonance imaging (MRI) in differentiating complete displaced (CD) thumb ulnar collateral ligament (UCL) tears from nondisplaced injuries in 10 patients with suspected traumatic thumb UCL injuries. surgeon Dr. Bertil Stener in 1962 •Yo-yo on a string appearance •Requires surgical repair to bring torn ligament back to proximal phalangeal base 41 year old women with thumb hyperextension injury.

MEDLINE, PubMed, Embase and Cochrane CENTRAL were searched for studies using ultrasound or MRI to detect Stener lesions following suspected thumb ulnar collateral ligament injuries. If with contrast, do non-fat-sat T1 post-contrast. Anatomy. 2015 Jan. 40 (1):90-5. . The interposition of the adductor pollicis aponeurosis between the retracted ulnar collateral ligament and the joint prevents healing unless surgical repair is performed. Author A Stener lesion has been described as having the appearance of a yoyo on a string on MRI. Further research is needed to elucidate the best imaging modality for accurate diagnosis of UCL lesions of the thumb. Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Collateral Ligament Injury, Fingers and Thumb 3) according to the consensus opinion. Xray - of D1 (thumb) - assess for fracture, avulsion of Ulnar collateral ligament. Both magnetic resonance imaging and ultrasonography (US) are cur- In a systematic review and meta-analysis, Qamhawi et al evaluated the diagnostic accuracy of US (nine studies; 315 thumbs) and MRI (six studies; 107 thumbs) for diagnosing Stener lesions of the thumb. The interposition of the adductor pollicis aponeurosis between the retracted ulnar collateral ligament and the joint prevents healing unless surgical repair is performed. 22 However, there are cadaveric studies reporting high sensitivity and specificity of MRI for the diagnosis of Stener lesions. Although knee Stener-like lesions have been previously de- DOI: 10.1007/s00256-012-1519-x Corpus ID: 206936665. evaluation for a Stener lesion requires MRI or high-frequency ultrasound these studies are usually performed after a diagnosis of gamekeeper's thumb has been made on a hand radiograph a Stener lesion is proximal retraction of the ligament fibers which looks like a small mass displaced superficial to the adductor aponeurosis; this gives the yo . Stener lesion of the thumb on MRI. There is approximately 7 mm of proximal retraction of the torn ligament with interposition of the adductor aponeurosis between the retracted ligament and the phalangeal attachment. Read rest of the answer. Acute injury to the ulnar collateral ligament of the metacarpophalangeal joint of the thumb is a condition frequently seen by hand surgeons. The ligament can displace superficially to the adductor pollicis aponeurosis, which is referred to as "Stener lesion" [ 16 ]. If hardware is present: Do STIR instead of fat-sat mid-TE. Abstract. Design. A Stener lesion is a complete tear of the ulnar collateral ligament (UCL) from the thumb proximal phalanx at the level of the metacarpophalangeal (MCP) joint that is displaced superficial to the adductor pollicis aponeurosis, leading to interposition of the aponeurosis between the UCL and the MCP joint. with the Stener lesion in 1 patient. Management: Patients with acute thumb pain, particularly after trauma, require prompt evaluation of structural integrity, thus avoiding long-term morbidity such as instability, chronic pain, and osteoarthritis. Magnetic resonance imaging. Magnetic resonance imaging may be used to optimally characterize soft tissues and bone marrow. The normal anatomy of this region and any potential UCL injury or Stener lesion can be seen reliably with either MR imaging or US (26,27). The aim of imaging is to define any fracture, determine if there is instability (joint space widening), and identify a Stener lesion. Six cadaver thumbs had ulnar collateral ligament (UCL) tears created surgically. The surgical findings of five Stener lesions and two complete ruptures of the UCL without a Stener lesion were correctly reviewed by both readers. Each radiologist reinterpreted the images after an interval of several days. Whether the injury is acute or chronic, a complete rupture of the ligament is usually managed with operative repair to restore thumb stability with pinch and grip, as well as to avoid arthritic changes. We have observed an analogous lesion in the knee where the anterior fibers of the superficial MCL were displaced over the pes anserinus tendons. The mechanism of the injury is abrupt radial stress to the UCL like a skier gripping a ski pole during a fall with the thumb in abduction. It is seen with a traumatic injury, called the "gamekeeper's thumb," in which there is a tear of the ulnar collateral ligament (UCL) at the level of the metacarpophalangeal joint. Design: MR examinations (2D STIR and 3D GRASS) were performed identically on all specimens both before displacement (non-Stener) and after displacement (Stener lesion) of the UCL.
