Specific acromesomelia with facial and renal anomalies: a new syndrome.

A facio-renal-acromesomelic syndrome is reported in a 15-year-old boy with normal intelligence. The main dysmorphic features are a large head and congenital ptosis with telecanthus. There is unilateral ureteral stenosis with hydronephrosis. Bone abnormalities consist of ulnar dysplasia and tibial hypoplasia, multiple synostoses of carpal and tarsal bones, proximal synostoses of metatarsals, and of brachydactyly. A similar case has not been published.

[Head posture in lateral roentgen image].

A cervico-cephalometric examination of 61 yet untreated orthodontic patients was performed in order to analyze differences in head posture between standardized cephalograms and lateral cephalograms taken in natural head position. Additional x-rays were taken in extreme flexion and extention of the head in 48 patients examining the mobility of the upper cervical spine. Finding partly large differences in cranio-vertical and cranio-cervical parameters between the two methods of registration it could be shown, that head posture on the average was more proclined in natural than in fixed standardized position. Subjects with class III malocclusion tended to a more extended head posture relatively to those with class I or class II malocclusion. Judging the atlas position with regard to the functional mobility of the upper cervical spine, a superior and inferior atlas position was not thought to be a pathologic fixed malposition.

[Craniocarpotarsal dystrophy (Freeman-Sheldon Syndrome)].

In the case of a woman with Freeman-Sheldon syndrome clinical, radiographic and CT data were used to demonstrate specific craniofacial and dental characteristics. Three-dimensional surface reconstruction of the cranial morphology obtained from axial CT scans was found to provide the most useful means for analyzing the characteristic craniofacial deformities in this syndrome. Apart from the dentofacial structures also orthopedic disorders were evaluated clinically and radiographically with particular consideration of the cervical spine morphology.

[3-D reconstruction for assessing the morphology of craniofacial structures].

The diagnostic value of 3-D reconstructions from axial CT scans in evaluating craniofacial structures was analyzed on the basis of a selected orthodontic patient group. The results showed that, for the first time, a three-dimensional analysis of the craniofacial relationships could be obtained which was not a mere spatial evaluation of the morphological structures. The specific application of this imaging procedure in detailed evaluations of complex dysmorphias and asymmetries seems to be justified.

[Roentgen morphologic study of arthrosis of the sternoclavicular joint].

X-rays of 102 sternoclavicular joints from post-mortem examination were interpreted systematically. In 89 cases we found an osteoarthrosis. We investigated the correlation between stage of osteoarthrosis and size and form of articular surface, age, sex and right or left preference. We also made a review about anatomy, embryology and pathology of the sternoclavicular joint. The differential diagnosis of sternoclavicular pain is discussed.

[Biometric analysis of the unstable shoulder].

An osteometry of instable glenohumeral-joints was done by computerized tomography. In comparison of type and direction of the instability, a marked retroversion of the glenoid was found in posterior luxation, not only in the instable, but also in the contralateral side. There seems no statistical prove of an influence by a changed radius or width of the humerus-head nor by a reduced retrotorsion of the humerus. Posttraumatic disorders like HILL-SACHS-lesions or BANKART-lesions are more easily detected by computerized tomography than by conventional radiography.

[The styloid syndrome. Differential diagnosis of degenerative diseases of the cervical vertebrae--case report with literature review].

Elongated Styloid Process Syndrome requires its consideration in differential diagnosis of degenerative disease of the cervical spine. Radiating pain on certain movements of the cervical spine is a symptom of an elongated styloid process as well. First basic anatomy and pathology, symptoms and differential diagnosis of the elongated styloid syndrome are discussed. A case history is presented together with X-rays of the cervical spine and images of three dimensional CT-reconstruction to show the full length of an elongated styloid process.
