1/97. Shear syndrome: the worst case scenario of crush syndrome.Shear syndrome is described as a complication of crush syndrome. In addition to compression of and injury to the electrode, complete transection occurs. In this case, the free end migrated to the pulmonary artery with the potential for further complications.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
2/97. Ultrasonographic localization of a displaced screw in the carpal canal. A case report.We present a case of a 65-year-old patient with a surgically treated distal radius fracture. At 5-month follow-up, conventional radiography revealed breakage of the plate and a screw displaced into the volar soft tissue. Preoperative ultrasonography including dynamic assessment of the tendons showed the screw intratendinously as a hyperechogenic structure with repetitive echoes. This unusual localization was proven by surgery. Dynamic ultrasonography played an important diagnostic role in the localization of the loosened and displaced osteosynthetic material.- - - - - - - - - - ranking = 16.460835909097keywords = fracture (Clic here for more details about this article) |
3/97. Intrapulmonary artery and intrabronchial migration and extraction of a fragment of J-shaped atrial pacing catheter.A fragment of a fractured Telectronics Atrial Accufix 330-801 lead asymptomatically perforated the adjacent bronchus and was detected on routine chest X-ray. The metallic fragment was located by chest CT scan and bronchial fluoroscopy to lie between the right lobar bronchus and the pulmonary artery, confirming bronchial perforation. The foreign body was removed without complication by direct visualisation with rigid bronchoscopy.- - - - - - - - - - ranking = 16.460835909097keywords = fracture (Clic here for more details about this article) |
4/97. Catheter fracture and cardiac migration: a rare complication of totally implantable venous devices.Totally implantable venous device (TIVD) are widely used for the treatment of patients requiring long-term chemotherapy, total parenteral nutrition and fluid replacement. Until today, many kinds of complications have been reported in the literature. We report an unusual case of catheter fracture as a consequence of pinchoff syndrome, and discuss the potential methods to avoid this complication and its evolution.- - - - - - - - - - ranking = 82.304179545485keywords = fracture (Clic here for more details about this article) |
5/97. Cruciate paralysis, hypothesis for injury and recovery.STUDY DESIGN: Case report and review of the literature. OBJECTIVES: Discuss a case of cruciate paralysis, a review of the literature and the hypotheses regarding the pathogenesis and recovery in spinal cord injuries that cause disproportionate weakness of the upper extremities. SETTING: Thomas Jefferson University Hospital, philadelphia, PA, USA. methods: Case report. RESULTS: A case of cruciate paralysis is presented involving a 59-year-old female who experienced a gunshot wound to the face. Initial motor exams revealed mild lower limb weakness and absent upper limb function with an upper limb modified American Spinal Injury association motor score of 0/50 (a modified impairment scale using half point muscle grades). Spinal imaging revealed fractures of the C1 anterior ring and the odontoid process, both associated with multiple bullet fragments. No spinal surgery was performed and she was placed in halo fixation. By 3 weeks she had regained enough upper limb function to manipulate large objects with her left hand and move her right hand. At that time, her upper limb asia score was 16/50. By 5 weeks, her upper limb modified asia motor score had improved to 31.5/50 and she began manipulating feeding utensils, writing legibly, and brushing her teeth with her left hand. CONCLUSIONS: In this case report we present a patient's motor and functional recovery. We also discuss the hypothesis that the acute central cord syndrome and cruciate paralysis are a likely result of similar pathologic mechanisms and that good functional outcome resulted from an initially disabling trauma.- - - - - - - - - - ranking = 16.460835909097keywords = fracture (Clic here for more details about this article) |
6/97. Intrathoracic migration of Steinmann pins.The migration of surgical wires and pins placed for repair of orthopedic injury is well recognized. Such migration usually follows a retrograde path and the wires protrude near their entry point into the native bone. Occasionally, the migration occurs in an antegrade manner and produces injury. We describe a case where three Steinmann pins placed for fixation of a humeral neck fracture migrated, one slipping backwards towards the humeral entry point and two pins migrating into the thorax.- - - - - - - - - - ranking = 16.460835909097keywords = fracture (Clic here for more details about this article) |
7/97. Duromedics original prosthesis: what do we really know about diagnosis and mechanism of leaflet escape?The Edwards-Duromedics (ED) is a bileaflet pyrolitic carbon mechanical valve introduced by Hemex Scientific Inc in 1982, subsequently acquired by Baxter Healthcare Corp, withdrawn from the market in 1988, and modified and reintroduced in 1990. From 1982 to date, 46 cases of leaflet escape have been registered by the manufacturer of an estimated total of 20,000 valves implanted. Disc embolization 12 years after an ED mitral prosthesis implantation is reported in a 45-year-old man operated on when he was in cardiogenic shock because a preliminary transthoracic Doppler echocardiography did not show malfunction of the valve. A correct diagnosis was made four days after the onset of the symptoms by transesophageal echocardiography. During the operation, the posterior leaflet of the ED valve was not found, a 29 mm St Jude Medical bileaflet mechanical prosthesis was implanted and the patient died in the intensive care unit because of low cardiac output syndrome. Cavitation damage is generally considered the most frequent mechanism in cases of such fracture. Thus, any patient with a mechanical valve presenting with acute pulmonary edema must be immediately transferred to a surgical unit; cinefluoroscopy or transesophageal echocardiography may be performed rapidly to achieve successful management of patients with leaflet embolization.- - - - - - - - - - ranking = 16.460835909097keywords = fracture (Clic here for more details about this article) |
8/97. Localization of concealed norplant implants and implant fragments by a modified mammography technique.A modified mammography technique for localization of concealed Norplant implants and Norplant fragments was applied to four patients, ages 18, 35, 22, and 25. A dedicated mammography unit and mammography film screen system affording high resolution and high contrast was applied under the same conditions to each patient. 26 kilovoltage peak (KVp) was used, ranging from 60 to 150 milliamperes. Using both the automatic exposure control and manual techniques, specific milliampere range depended on the specific case. The technique proved successful, as concealed Norplant capsules were exquisitely visualized by films obtained with a Siemens Mammomat 3000. Applying the same modified technique, precise location of the Norplant implants was determined using a fenestrated compression plate with an alphanumeric grid in a manner similar to hookwire localization of breast lesions under mammographic guidance. The capsules were then safely retrieved. We conclude that this modified technique may provide practitioners with valuable assistance in the exact localization of the Norplant capsule(s) or fragments, thereby facilitating their removal.Application of a modified mammography technique reveals precise localization of concealed Norplant capsules facilitating their removal.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
9/97. Removal of an intrathoracic migrated fixation pin by thoracoscopy.Migration of orthopedic fixation pins into the thoracic cavity can result in perforation of pulmonary vasculature, aorta, bronchus, atrium, or ventricle. Prompt diagnosis and treatment is tantamount in preventing devastating consequences. A patient who had fixation of a right humeral fracture weeks later had intrathoracic migration of a fixation pin, found by routine postoperative radiographic examination. Because the patient was asymptomatic, we removed the pin with a thoracoscopic operation. The foreign body was retrieved successfully without intraoperative or postoperative complication.- - - - - - - - - - ranking = 16.460835909097keywords = fracture (Clic here for more details about this article) |
10/97. A rare complication of percutaneous iliosacral screw in a vertically unstable pelvic disruption in a child.The use of iliosacral screws in managing vertically unstable fractures in adults has been popularised and the early results are quite promising. However, the role and indication of this technique in paediatric patients are not clear. There has been a concern about its safety and risk of screw misplacement.- - - - - - - - - - ranking = 16.460835909097keywords = fracture (Clic here for more details about this article) |
