AIM The aim of this retrospective study was to report the scapular fractures in patients with blunt chest trauma and to present the type and the frequency of associated thoracic injuries. MATERIAL AND METHODS Nine patients with fractures of the scapula were included in the study. The mechanisms of the injury, the type of scapular fractures and associated thoracic injuries were analysed. RES...

BACKGROUND AND PURPOSE Scapular excursion and the wrist speed were studied before and after instruction and practice designed to achieve symmetrical scapular movement. SUBJECTS Subjects were 10 female and 6 male patients, aged 44 to 78 years (chi=60.3, SD=11.2), with diagnosed shoulder pathologies. METHODS Subjects were videotaped performing a reaching task. Pain status was monitored. The s...

Context: In vivo scapular kinematics during humeral movements are commonly assessed with electromagnetic tracking devices despite few published data related to reliability and precision of these measurements. Objective: To determine the intrasession reliability and precision of assessing scapular kinematics using an electromagnetic tracking device. Design: Scapular position and orientation were...

The scapula functions as a bridge between the shoulder complex and the cervical spine and plays a very important role in providing both mobility and stability of the neck/shoulder region. The association between abnormal scapular positions and motions and glenohumeral joint pathology has been well established in the literature, whereas studies investigating the relationship between neck pain an...

The purpose of this study is to determine if scapular stabilizer weakness and instability is a plausible explanation for excessive winging and/or tipping of the scapula in females who participate in overhead sports. Instability may be an early sign of weakness that can contribute to shoulder injury. Literature regarding causes of scapular winging and tipping pertaining to weak scapular stabiliz...

p i J a To the Editor: The transition from the QRS complex to the ST-segment on the 12-lead electrocardiogram (ECG) has been conventionally termed the ST junction (STj). Occasionally, the terminal portion of the QRS complex manifests a notch or slur when transiting into the ST-segment. This has been described as a normal variant in healthy individuals (1) in whom STj is very often elevated. The...

[Purpose] This study investigated the effect of the spacing of backpack shoulder straps on cervical muscle activity, acromion and scapular position, and upper trapezius (UT) pain. [Subjects] Fourteen males aged 20-32 years, were recruited. [Methods] We measured the MPS (midcervical paraspinal) activity, acromial angle, scapular distance, and UT pain after gait carrying a backpack with different...

[Purpose] This study investigated the changes in acromion and scapular position after short-term overhead work. [Subjects] Twelve males aged 20-27 years, were recruited. [Methods] We measured the acromial angle and scapular inferior distance using a palpation meter before and after overhead work. [Results] The acromion angle was significantly decreased after the overhead work compared to before...

One of the best-characterized lineage restrictions in developing vertebrates occurs between adjacent -rhombomeres of the hindbrain. It was recently shown that cells at the boundaries of zebrafish rhombomeres also differ from non-boundary cells in their migratory abilities, a difference driven by Notch signaling.

The increased incidence of high-frequency components (notching) in electrocardiographic (ECG) recordings previously has been related to coronary artery disease, primary myocardial disease, and biventricular enlargement. This study included 130 subjects on whom autopsy permission was obtained, who had one or more sets of high-frequency, orthogonal ECG (XYZ) leads and directwriting standard ECG l...
