OBJECTIVE To evaluate the presence of the anterolateral ligament (ALL) of the knee in magnetic resonance imaging (MRI) examinations. METHODS Thirty-three MRI examinations on patients' knees that were done because of indications unrelated to ligament instability or trauma were evaluated. T1-weighted images in the sagittal plane and T2-weighted images with fat saturation in the axial, sagittal ...

Background The traction bed is a noninvasive device for treating lower back pain caused by herniated intervertebral discs. In this study, we investigated the impact of the traction bed on the lower back as a means of increasing the disc height and creating a gap between facet joints. Methods Computed tomography (CT) images were obtained from a female volunteer and a three-dimensional (3D) mod...

CONTEXT There exists controversy on the ability of a single or double anterior cruciate ligament graft technique to restore anterior cruciate ligament function. This article examines the published experimental and clinical data supporting these surgical procedures in the ability to restore knee stability. EVIDENCE ACQUISITION An analysis of anterior cruciate ligament function and single- and ...

BACKGROUND The effect of elbow medial ulnar collateral ligament injury on posteromedial compartment contact is unknown. HYPOTHESIS Medial ulnar collateral ligament injury causes altered contact area and pressure in the posteromedial compartment of the elbow. STUDY DESIGN Controlled laboratory study. METHODS Seven elbow cadaveric specimens were tested in an apparatus that positioned the el...

The aim of the present study was to investigate the anatomical and morphological characteristics and the maximum elongation of the calcaneofibular ligament (CFL) in cadavers. In a sample of 72 cadaveric lower limbs the mean values of length, width, thickness, and angle with the sagittal plane were recorded for the CFL. The mean ligament's length was 31.8 mm, and the mean width and thickness wer...

We treated 43 acute tears of the calcaneofibular ligament by operation in 43 patients after subtalar arthrography. There were 22 men and 21 women with a mean age of 22.3 years (14 to 61). Anteroposterior (AP), lateral and oblique views were obtained with the foot in 45 degrees of internal rotation and the ankle in the neutral position. Any communication or leakage to the ankle, tendon sheaths, ...

Introduction Complete or partial ossification of the pterygospinous ligament that connects the posterior border of the lateral pterygoid plate to the spine of the sphenoid bone occurs in 1-31.2% of people [1,2]. The ossified pterygospinous ligament is detected on the lateral or medial side or crossing over the foramen ovale on the radiographs of the dry scull in the axial projection with the be...

STUDY DESIGN A biomechanical study using a cadaver model was conducted to define the function of the nuchal ligament in the restraint of flexion of the cervical spine. OBJECTIVE To test the hypothesis that surgical resection of the nuchal ligament significantly reduces the structural restraints to cervical flexion. SUMMARY OF BACKGROUND DATA Although previous studies have examined the role ...
