A study of 18 elbows in the cadaver allowed the medial fascia of the radial collateral ligament of the articular capsule to be clearly separated. Section of this ligament associated with that of the anterior fascia, without section of the ulnar collateral ligament always produces luxation of the elbow if it is in flexion. The integrity of the insertion(More)
PURPOSE To determine the magnetic resonance (MR) imaging features of subungual glomus tumors. MATERIALS AND METHODS Thirty-one patients with a clinical suspicion of glomus tumor and 10 control subjects underwent MR imaging at 1.5 T. MR images of normal glomus bodies of a cadaver finger were correlated with histologic slices. With a local surface gradient(More)
Ossifications in the caudal attachments of the ligamentum flavum were studied on 121 dried thoracic spines. Most of them were aged. Frequency increased in a caudal direction. At T12, frequency depended on the orientation of the zygapophyseal joints of T11-12 which determined the range of rotation. When they were of thoracic orientation, allowing large range(More)
BACKGROUND High-resolution magnetic resonance imaging (MRI) of subungual glomus tumors has been recently reported. OBJECTIVE Our purpose was to compare high-resolution MRI and standard MRI for the diagnosis of 44 glomus tumors of the toes and fingertips. METHODS Glomus tumors (11 cases) were first examined by MRI with a commercial surface coil (set 1).(More)
The piriform aperture or enter orifice of the nose may be too small, creating an obstacle for inspirated flow. The functional disturbance realised has been described as the "syndrome of aspiration of the nasal ala". The present study has been made on 100 skulls. We have measured the dimensions of the piriform aperture, calculated a "form index" and searched(More)
On the supposition that some "pseudocoxalgias" might be due to a neuralgia of the lateral rami leaving the subcostal and iliohypogastric nerves above the lateral edge of the iliac crest, the authors undertook an anatomic study of their pathways and pattern of distribution. These rami supplying the skin below the iliac crest, which they cross close together,(More)
Access to the cervicothoracic junction, whether by lower anterior cervical or transthoracic approach, is particularly difficult. The authors propose partial cervicosternotomy which allows the T3-T4 disk to be reached satisfactorily in 50% of cases and in the remaining 50% allows direct anterior control of the upper two thirds of T3. The advantage of this(More)
Manual compression of the vertebral artery is used in routine clinical practice for diagnosis of positional hemodynamic vertebro-basilar insufficiency (VBI). The supraclavicular and suboccipital areas were carefully dissected in 20 cadavers. Anatomical variations observed on dissection were compared to angiographic data from 150 patients and data from the(More)
The authors have injected the arteries and dissected 79 wrists. They propose a systematization of the vascular supply of the carpus, based on the major longitudinal and transverses axes; on the areas of arterial convergence and divergence, at the origin of 2 systems: the deep system (SAPRUC) is a vestige of the foetal morphology; it is periostal and(More)
High-resolution sagittal magnetic resonance images depict an oval area in the dermis beneath the nail matrix that gives a particular signal. This study defines the magnetic resonance imaging characteristics of this area and examines its correlation with the lunula. A high-resolution surface gradient coil specially designed for skin imagining was used on a(More)
