Based on our clinical experience, the H-reflex amplitude asymmetry might be an earlier sign of nerve root involvement than latency in patients with S1 radiculopathy. However, no data to support this assumption are available. The purpose of this study was to review and report the electrophysiological changes in H-reflex amplitude...

Cervical spondylosis is a common degenerative condition of the cervical spine. It is most likely caused by age-related changes in the intervertebral disks. Clinically, several syndromes, both overlapping and distinct, are seen. These include neck and shoulder pain, suboccipital pain and headache, radicular symptoms, and cervical spondylotic myelopathy (CSM). As...

Femoroacetabular impingement may occur in patients with so-called acetabular retroversion, which is seen as the crossover sign on standard radiographs. We noticed when a crossover sign was present the ischial spine commonly projected into the pelvic cavity on an anteroposterior pelvic radiograph. To confirm this finding, we reviewed the anteroposterior...

Although the ischial spine sign (ISS) has been advocated to detect acetabular retroversion, it is unknown whether the sign is valid on anteroposterior (AP) pelvic radiographs with tilted or rotated pelves. We therefore evaluated reliability of the ISS as a tool for diagnosing acetabular retroversion in the presence of considerable...

Results We evaluated this test in 20 patients clinically and by magnetic resonance imaging (MRI). All patients demonstrated a positive internal rotation lag sign. Twelve of them lag of internal rotation and evidence of anterior abductor tendon rupture on MRI, 8 with lag of internal rotation and no evidence of abductor...

The glenoid labrum is a triangular fibrocartilaginous structure that serves to deepen the glenoid. While tears of the anteroinferior labrum have long been known to be associated with significant shoulder pathology, injuries of the superior labrum have really only been appreciated as a potential pathological lesion since the advent of...

The Scottish Intercollegiate Guidelines Network (SIGN) was formed in 1993. Our objective is to improve the quality of health care for patients in Scotland by reducing variation in practice and outcome, through the development and dissemination of national clinical guidelines containing recommendations for effective practice based on current evidence.

The teardrop sign, which can be seen on the standard lateral radiograph of the ankle in the neutral position, is useful in diagnosing ankle effusions of 5 mL or larger.

The Surgical Implant Generation Network (SIGN) was established in January of 1999 as a humanitarian, nonprofit corporation in the State of Washington, USA. SIGN's goal is to provide for improved health-care and proper orthopaedic treatment of fractures at little or no cost to people in need throughout the world. Expert

Cervical spondylosis is a chronic degenerative condition of the cervical spine that affects the vertebral bodies and intervertebral disks of the neck (in the form of, for example, disk herniation and spur formation), as well as the contents of the spinal canal (nerve roots and/or spinal cord). Some authors also...

Conclusion The results support the hypothesis that gluteus medius tendon pathology is important in defining GTPS. In this series, trochanteric bursal distension was uncommon and did not occur in the absence of gluteus medius pathology. The physical findings suggest that Trendelenburg's sign is the most sensitive and specific physical sign for...

Soft tissue injuries of the knee are some of the most common and clinically challenging musculoskeletal disorders in patients presenting to the ED. Therefore, establishing clear-cut diagnostic and therapeutic objectives for these injuries is important. Knee pain and related symptoms may derive from damage to 1 or more of the soft...
