1/143. Eighteen fractures in a man with profound mental retardation.A 39-year-old man with generalized tonic clonic epilepsy and profound mental retardation sustained 18 fractures (15 in appendicular and 3 in axial bones) during 19 years. Both femoral necks were fractured, requiring surgical repair. Although he had been on antiepileptic drugs for 35 years, he had no radiographic or biochemical sign of osteomalacia. He had a very low bone mineral density, suggesting osteoporosis. This case illustrates an important medical problem affecting people with developmental disability and a management challenge for their caretakers.- - - - - - - - - - ranking = 1keywords = fracture (Clic here for more details about this article) |
2/143. Femoral fracture at the proximal end of an intramedullary supracondylar nail: a case report.Retrograde intramedullary supracondylar nails have been added to the orthopedic armamentarium for treatment of distal femoral fractures. Major complications of this new technique have not been noted. We report a case of a femoral fracture at the proximal end of a retrograde intramedullary supracondylar nail. We hypothesize that this complication may be due to the proximal end of the nail acting as a stress riser, with the cortical holes drilled for the interlocking screws compounding this effect.- - - - - - - - - - ranking = 1keywords = fracture (Clic here for more details about this article) |
3/143. Unusual longitudinal stress fractures of the femoral diaphysis: report of five cases.We present five cases of a distinctive type of longitudinal stress fracture of the upper femoral shaft in which the fracture line is parallel to the outer surface of the bone, in contrast to the perpendicular orientation to the cortical surface in previously reported cases of diaphyseal stress fractures. In two cases the fracture recurred after 15 and 18 months, respectively.- - - - - - - - - - ranking = 1.3333333333333keywords = fracture (Clic here for more details about this article) |
4/143. ophthalmoplegic migraine and periodic migrainous neuralgia, migraine variants with ocular manifestations.The spectrum of migraine has been outlined with particular attention to two entities: ophthalmoplegic migraine and Periodic Migrainous neuralgia. Although quite different in many respects from classical migraine, the relationship of a periodic localized vascular phenomenon giving rise to headache and transient neurologic signs, classify PMN and OPGM as migraine variants. Supportive of this concept, the literature has been reviewed in both entities, and some observations are made on the validity of earlier reports. It is the author's opinion that Raeder's syndrome should be reserved for patients with a lesion localizing in the paratrigeminal area. This does not exclude migraine as an etiologic agent but also recognizes tumors, infections and fractures as being more common.- - - - - - - - - - ranking = 0.16666666666667keywords = fracture (Clic here for more details about this article) |
5/143. Polycystic bone disease: A new, autosomal dominant disorder.We describe a new heritable bone disease characterized radiographically by increasingly numerous and enlarging cyst-like lesions throughout the skeleton. Beginning in early childhood, a father, son, and daughter all suffered from progressively frequent pathological fractures involving such radiolucencies. Healing occurred uneventfully and with little residual pain or deformity. Biochemical parameters of mineral homeostasis and skeletal turnover were normal. Bone scanning showed increased radioisotope uptake primarily in fractures and in the largest collections of the lesions. The histopathology is uncertain, but may reflect a form of intraosseous lipomatosis. This unique condition, which we have provisionally named polycystic bone disease, is inherited as an autosomal dominant trait with a high degree of penetrance.- - - - - - - - - - ranking = 0.33333333333333keywords = fracture (Clic here for more details about this article) |
6/143. Differences between scar and dermal cultured fibroblasts derived from a patient with recurrent abdominal incision wound herniation.fibroblasts were derived from dermis and scar of a 47-year-old white man with a recurrent incisional hernia as a result of fractured ribs. The scar was thin and stretched, suggesting a defect in the maturation of granulation tissue. After surgical repair, biopsy specimens of discarded scar and skin were used to generate fibroblast cell lines. fibroblasts maintained in medium containing 10% fetal bovine serum and antibiotic were studied between their third and eighth passage. By phase contrast microscopy, no structural differences were obvious, but it was noted that to pass scar fibroblasts, a more aggressive trypsin regimen was required. Immunohistologic and Western blot analysis of patient scar fibroblasts showed (1) more a smooth muscle actin within stress fibers, (2) increased expression of the vitronectin integrin receptor alpha(v) (CD 51), and (3) reduced expression of the collagen integrin receptor alpha2 (CD 49b). The expression of vinculin from focal adhesions or a tubulin from microtubules was the same among cell lines. Contractions of scar and dermal fibroblast-populated collagen lattice were compared. At 24 hours, contractions were 69 percent with newborn fibroblasts (normal); 68 percent for patient dermal fibroblasts; and only 48 percent for patient scar fibroblasts. The retarded contraction of scar fibroblast-populated collagen lattice was significant (p > or = 0.002). Myosin ATPase activity, critical for lattice contraction, and cell migration were equivalent among all cell lines. A plausible mechanism for the retardation of scar lattice contraction is disruption of fibroblasts and collagen interactions, for which the attachment of cells to collagen is altered. It is proposed that either the decrease in the expression of collagen integrin receptor alpha2 (CD 49b), an increase in the expression of the vitronectin receptor alpha(v) (CD 51), or a combination of both is responsible for disruption of collagen fibroblast interactions.- - - - - - - - - - ranking = 0.16666666666667keywords = fracture (Clic here for more details about this article) |
7/143. An operative technique for recurrent shoulder dislocations in older patients.Recurrent anterior shoulder dislocation in the elderly is not as exceptional as it was once thought to be. That anterior shoulder dislocation in older patients is caused by a rotator cuff tear through the posterior mechanism is well accepted. However, in the subset of patients who have multiple recurrent or intractable dislocations develop, there may be combined pathologic conditions at work: large or massive rotator cuff tears together with anterior capsulolabral injuries such as a Bankart lesion or fracture of the glenoid rim. These patients have multiple recurrences because of disruption of both the anterior and the posterior stability mechanisms. We suggest a procedure that provides anterior stabilization with the capsular shift technique and that is supplemented by Bankart repair as necessary. The capsule transfer is performed superiorly and posteriorly to close the defect in the cuff. In this way a capsulodesis effect can be achieved that displaces the humeral head downward and produces active centering of the head in the course of abduction. Use of only the anterior capsule for the shift, and not the subscapularis tendon, does not compromise subscapularis function. Between 1990 and 1996, we used this technique to treat 16 patients older than 55 years of age with multiple recurrent anterior shoulder dislocation and massive rotator cuff tear. We report the results for the first 10 patients with a minimum follow-up of 2 years (range 2 to 7 years) and an average follow-up of 52 months. There were 7 excellent results, 2 good results, and 1 fair result according to the Rowe criteria. None of the patients had a recurrence of the dislocation. All the patients regained full or functional range of motion with stable shoulders, and most of them could perform activities of daily living without limitation. The average Constant score was 83%. This procedure appears to be successful in treating older patients with recurrent shoulder dislocation.- - - - - - - - - - ranking = 0.16666666666667keywords = fracture (Clic here for more details about this article) |
8/143. New techniques for surgical decompression of thyroid-related orbitopathy.Certain cases of thyroid-related orbitopathy may require surgical decompression of the orbit. The purpose of this paper is to highlight new techniques of orbital decompression in thyroid-related orbitopathy. We present two illustrative cases selected from our recent surgical experience. The techniques of combined-approach decompression, transcaruncular approach to the medial orbital wall, drilling reduction of the greater wing of sphenoid and lateral wall lag-screw fixation after lateralization by greenstick fracture are presented. The relative utility of each technique is examined. These techniques expand the surgical repertoire for this condition and allow individualization of treatment for a specific patient's needs.- - - - - - - - - - ranking = 0.16666666666667keywords = fracture (Clic here for more details about this article) |
9/143. Recurrent fracture of the humerus in a softball player.Fracture of a normal humerus can occur during the act of throwing an object. We present the case of a young woman who sustained a spiral fracture of the distal humeral shaft with concomitant radial nerve palsy while throwing a softball and who, after clinical and radiographic evidence of bony healing, suffered a repeat humerus fracture, also while throwing a softball.- - - - - - - - - - ranking = 1keywords = fracture (Clic here for more details about this article) |
10/143. Occult fractures of tibial plateau detected employing magnetic resonance imaging.We describe two cases of spontaneous fracture at the tibial metaphysis not diagnosed by standard X-ray. In both cases, only magnetic resonance imaging supplied a precise diagnosis and allowed us to follow the evolution of the pathology. Scintigraphy is equally sensitive but unspecific. osteoporosis was noted in all cases. Hypothetically, similar pathological situations could be present without being diagnosed since they are not always detected by standard x-rays.- - - - - - - - - - ranking = 0.83333333333333keywords = fracture (Clic here for more details about this article) |
