1/7. Glenoid dysplasia. A case report and review of the literature.Glenoid dysplasia is a rare congenital abnormality that may be associated with vague shoulder pain, limitation of motion, and weakness of the upper extremity. In many cases it is an incidental finding on chest roentgenogram, and high-level function is usually possible before the onset of symptoms or degenerative changes. The case of an 18-year-old collegiate football offensive lineman who developed symptoms secondary to previously undetected bilateral glenoid dysplasia is reported. Roentgenograms demonstrated dysplastic scapular necks, and arthrography showed a deformed, constricted shoulder capsule. Magnetic resonance imaging defined the extent of the cartilaginous anlage, and arthroscopy demonstrated progressive articular cartilage degeneration. Although treatment alleviated the shoulder symptoms at low-level activities, the patient was unable to successfully compete under the extreme demands of an American football lineman.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
2/7. humerus varus in a patient with pseudohypoparathyroidism.A 7-yr-old girl presented with progressive shortening of the right upper arm and limitation of shoulder motion. pseudohypoparathyroidism associated with Albright's hereditary osteodystrophy was diagnosed by biochemical, hormonal and radiographic studies. Her condition was complicated by severe humerus varus on the right side. Proximal humeral valgization osteotomy and concomitant humeral lengthening resulted in an improvement of the shoulder joint motion and activity in daily life.- - - - - - - - - - ranking = 2keywords = motion (Clic here for more details about this article) |
3/7. mitral valve prolapse in a patient with frontometaphyseal dysplasia.Frontometaphyseal dysplasia (FMD) was described by Gorlin and Cohen 1969. Since then, 20 cases have been reported. The common findings include a characteristic face with particularly prominent supraorbital ridges, defective vision, hearing and dentition, micrognathia, high arched palate, winged scapulae, limited joint motion, and poorly developed musculature. Despite the presence of a heart murmur described in several patients, a specific cardiac lesion has not been diagnosed. This report describes a patient with mitral valve prolapse (MVP) and FMD.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
4/7. Nonunited ossification center of the presphenoid bone: pseudomeningioma.Three patients are described; in two of them initial plain skull films at an outside institution were interpreted as demonstrating an anterior clinoid meningioma. Evaluation of these films along with further study of the skull base with complex motion tomography demonstrated a separate and well corticated bony structure posterior and superior to each anterior clinoid in all three cases. After review of the developmental anatomy of this region, it was concluded that these bone centers represent failure of the posterior accessory centers of the presphenoid to fuse with the orbitosphenoid. The features of these nonunited centers appear to be characteristic and should allow distinction of this developmental anomaly from a pathologic process.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
5/7. Rotational acetabular osteotomy for the dysplastic hip.A circumacetabular osteotomy of the acetabulum was initially done at the University of tokyo Hospital by one of us (H. T.) in 1968. This procedure, which rotates the acetabulum, was designed to correct a dysplastic acetabulum in adolescents and adults. The surgical exposure combines both an anterior and a posterior approach. Between 1974 and 1982 this operation was performed on 103 patients (120 hips) with acetabular dysplasia, some showing early degenerative arthritis. The forty-five hips (forty-one patients) that form the basis of this report were followed for three years to eight years and ten months (average, four years and six months). Thirty hips showed only acetabular dysplasia, and fifteen were in the early stage of degenerative arthritis. The ages of the patients at the time of operation ranged from eleven to forty-two years, the majority being in the second or third decade of life. All of the forty-five hips had a preoperative center-edge angle of 10 degrees or less, but most of them had a nearly normal value after surgery. In the majority of the hips either limp or pain with exertion, or both, had disappeared, and a satisfactory range of motion had been restored.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
6/7. A surgical technique of radioulnar osteoclasis to correct severe forearm rotation deformities.Twenty-six forearms in 23 patients with marked pronation or supination deformities were treated with osteoclasis. Etiologies included 12 radioulnar synostoses, five brachial plexus injuries, three hemiplegias, two hemimelias, and four other types of deformities. Drill-assisted osteotomy of both the radius and ulna was followed 10 days later by manipulation to the desired functional position. Dominant extremities were placed in 20 degrees pronation, and nondominant extremities in 20 degrees supination. Range of motion was not significantly changed, but the arc of motion occurred in a more functional hand position. Average correction for 15 pronation deformities was 81 degrees and 69 degrees for 11 supination deformities. Two nonunions healed after bone grafting and there were no instances of neuromuscular compromise. Functional improvement was obtained in 25 of 26 forearms.- - - - - - - - - - ranking = 2keywords = motion (Clic here for more details about this article) |
7/7. Congenital glenoid dysplasia: case report in two consecutive generations.Congenital glenoid dysplasia is a rare congenital condition of the shoulder. We report the case of a 6-year-old girl that was referred to our institution for restricted motion of both shoulders. Radiological examination revealed bilateral glenoid dysplasia. At the time of the child's examination, her mother also complained of shoulder stiffness; radiographs of her shoulders were taken and revealed that she too had glenoid dysplasia. Congenital glenoid dysplasia results from failure of development of the inferior ossification center of the glenoid fossa. Shoulder stiffness is the primary resultant disability, although it is variable. Our case is notable because we identified the dysplasia in two successive generations of the same family, although the mother was unaware she had the condition.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
