We can predict how an object would look if we were to see it from different viewpoints by imagining its rotation. This essential human ability, called mental rotation (MR), guides individuals' actions by constantly updating their environmental consequences. It is, however, still under debate whether the way in which our ...

Computed tomography (CT) was used to diagnose the cause of lameness in a radiated tortoise (Geochelone radiata) and to determine the extent of shell and skeletal trauma in two snapping turtles (Chelydra serpentina). The radiated tortoise's lameness was ultimately attributed to luxation of the right-shoulder joint that was not detected ...

Since partial-thickness tears of the rotator cuff were described well by Codman in 1934, they have been extensively discussed in all kinds of literatures. Partial-thickness tears of the rotator cuff are now considered to play a more significant role than previously in inducing patients' disability. Partial-thickness cuff tears deserve more ...

This research questioned the proposition that corporate familiarity is positively associated with firm reputation. Student images of familiar and unfamiliar Fortune 500 corporations were examined in 4 experiments. The results suggested that, consistent with behavioral decision theory and attitude theory, highly familiar corporations provide information that is more compatible with ...

OBJECTIVE: Partial thickness tears of the undersurface (articular surface) of the rotator cuff (RTC) have been recognized increasingly in recent years as a source of treatable shoulder pain in the athletic population. This study evaluated the efficacy of MR arthrography (MR-ARTH) in diagnosing these tears. DESIGN AND PATIENTS: The study ...

We present the results of a preliminary study on the use of 3-D software (Photomodeler) for identification purposes. Perpetrators may be photographed or filmed by surveillance systems. The police may wish to have these images compared to photographs of suspects. The surveillance imagery will often consist of many images of ...

Most studies of rotator cuff repairs report high success rates. However, the majority of these studies combine the results of surgical management of rotator cuff tears of various sizes; few published reports specifically evaluate the management of chronic massive tears. Chronic massive rotator cuff tears may be acute traumatic, chronic ...

Radiographs and CT scans of 25 patients evaluated predominantly for glenohumeral joint instability ...

Shoulder pain and immobility comprise a multifactorial disorder apparently affected by pain inhibiting joint motion. As the syndrome is very common, many patients do not undergo detailed imaging studies before treatment. This study compared a series of 7 patients in whom a neoplasm was the underlying cause for the stiff ...

BACKGROUND: Although several studies have described magnetic resonance imaging findings in shoulders of asymptomatic volunteers, no such investigation has been performed on asymptomatic dominant and nondominant shoulders of elite overhead athletes. HYPOTHESIS: Asymptomatic dominant shoulders of elite overhead athletes may have a higher incidence of magnetic resonance imaging abnormalities than ...

Background. There is constant increase in number of patients seeking medical help due to shoulder diseases. Imaging techniques may facilitate making the diagnosis and decide about the treatment modality, including decision on operative treatment. Magnetic resonance is widely accepted for imaging of soft tissue lesions of the shoulder. <br /> ...

Sacroiliac joint (SIJ) injection and arthrography have been described, yet no study has specifically categorized the morphological characteristics of SIJ arthrograms versus post arthrogram computerized tomography (CT).

We examined the intensity of the supraspinetus muscles of patients with a rotator cuff tear in Magnetic Resonance Imaging (MRI) findings. 109 shoulders in patients with rotator cuff tears were preoperatively scanned by MRIs. Using MRIs, the linear bands of the supraspinatus muscle were classified into three grades. Between each ...

BACKGROUND: Evaluation of the rotator cuff in a shoulder that has been persistently painful postoperatively could be challenging. Magnetic resonance imaging has been the preferred imaging method, but accuracy rates have been lower for those shoulders than for shoulders that have not been operated on; also, magnetic resonance imaging is ...

OBJECTIVE: To examine the accuracy of Grashey views obtained during shoulder arthrography in the diagnosis of clinically relevant superior labrum anterior-posterior (SLAP) lesions. DESIGN AND PATIENTS: Grashey views obtained during diagnostic arthrography (conventional and MR) were used to examine the superior labrum. Twenty-eight of 118 shoulder arthrograms obtained during a ...

When a rotator cuff tear occurs, forces compressing the humeral head toward the glenoid are disturbed, and the kinematics of the glenohumeral joint change. Therefore, stress distributions at the coracoacromial arch in cuff tear shoulders should differ from those in normal shoulders. To investigate this hypothesis, we studied stress distribution ...

Lesions leading to glenohumeral instability may result from acute trauma, atraumatic laxity, or repetitive microtrauma. Athletic activities, especially overhead throwing, may lead to a series of lesions involving the stabilizing structures of the shoulder. The resultant injuries and pathomechanics leading to shoulder symptoms can be classified as primary disease, primary ...

We studied magnetic resonance images of rotator cuff tears to determine whether it was possible to establish preoperatively the feasibility or infeasibility of primary repair. The study comprised 27 shoulders in 26 patients who underwent magnetic resonance imaging before surgery because of complete tears of the rotator cuff and who ...

Impingement pain and rotator cuff injury are common in athletes, particularly in overhead throwers. The cuff can be injured in these patients in the typical location in the anterior supraspinatus tendon and near the junction of the supraspinatus and infraspinatus tendons. The cuff tears in athletes are usually small, articular ...
