1/17. 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 = 1keywords = upper (Clic here for more details about this article) |
2/17. Broken Ender nails after fixation of concomitant ipsilateral fractures of the femoral neck and shaft.Concomitant ipsilateral fractures of the upper part and shaft of the femur are uncommon injuries. Because of the small number of cases reported and the diversity of devices used, no single type of internal fixation stands out as the best treatment for both of these fractures. This report describes a case of concomitant ipsilateral fractures of the femoral neck and shaft that is further distinguished by a rare complication: breakage of Ender nails after fixation.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
3/17. Plating of femoral shaft fractures. A review of 15 cases.The objective of this study was to define the role, indications and outcome of plating in femur shaft fractures. All femoral shaft fractures admitted and treated by the authors during a 2-year period were analysed. The authors personally treated a total of 135 femur fractures. Of these 135 fractures, 15 (11%) were treated with primary plating. The femoral fractures were classified as grade I (n = 4), grade III (n = 3), grade IV (n = 4), grade V (n = 3), and grade VII (n = 1) (OTA classification). Three patients sustained open fractures (one grade I and two grade II, Gustilo and Anderson classification). Pelvic (6) or ipsilateral lower extremity injuries (4) occurred in 10 of the 15 patients. A total of 23 body areas were injured, most commonly the chest (n = 10), abdomen (n = 5), head (n = 6) and blood vessels (n = 3). There were no infections reported. Two implant failures were noted. femur plating is a useful technique in polytrauma patients for specific indications where intramedullary nailing (IMN) may be contra-indicated or technically not feasible. Although the postoperative morbidity (ARDS, death) in our study seems to be lower after plating than after intramedullary nailing, the rate of complications of fracture healing (30%) is significantly greater with femur plating than with intramedullary nailing (12%).- - - - - - - - - - ranking = 1.1806825629662keywords = chest (Clic here for more details about this article) |
4/17. Long-term survival of a patient with malignant lymphoma of bone.Malignant lymphoma of bone is an uncommon tumour. A number of studies have outlined the clinicopathological findings and overall favourable prognosis in adults. We report on a woman whose tumour was originally diagnosed as a secondary carcinoma of the upper femur. Twenty-three years later following proximal femoral replacement, the original histology was reviewed using immunohistochemical techniques and revised to B-cell malignant lymphoma of bone.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
5/17. bone marrow sampling in pathologic fractures: intramedullary pediatric chest tube technique.The objective of this article is to report upon a simple technique of bone marrow specimen collection of intramedullary bone tumors using a pediatric chest tube. This technique is described along with two case reports which include a 60-year-old female with metastatic breast cancer to the proximal femur, and a 63-year-old male with multiple myeloma of the proximal humerus. Utilizing this technique, in our experience, over 50 mL of aspirate can be obtained and definitive histologic material for cytogenetic diagnosis and immunohistochemistry. This technique is not indicated for biopsy of suspected primary lesions of bone due to the possibility of medullary or hematologic seeding and inappropriate invasion of soft tissue compartments.- - - - - - - - - - ranking = 5.903412814831keywords = chest (Clic here for more details about this article) |
6/17. Early intrathoracic migration of Kirschner wires used for percutaneous osteosynthesis of a two-part humeral neck fracture: a case report.We present an unusual case of early migration of three Kirschner wires used for percutaneous osteosynthesis of a two-part humeral neck fracture, causing hemothorax. An 85-year-old woman was admitted to the emergency room after casual accident. She was found to have suffered a two-part fracture of the surgical neck of the right humerus. The humeral fracture was treated by closed reduction and percutaneous osteosynthesis with three threaded Kirschner wires, which were bent subcutaneously. Ten days after the accident the patient presented with dyspnea and laterocervical pain. Plain x-rays and complementary CT demonstrated intrathoracic migration of the three Kirschner wires with hemothorax. Two of the wires were seen under the right clavicle and adjacent to the C7 vertebra. The third wire reached the lateral chest wall. Immediate surgery was performed, with withdrawal of the wires and placement of a drainage tube. The patient had an uneventful recovery after surgery. The humeral fracture resulted in a nonunion, which was well tolerated by the patient and was left untreated. The use of Kirschner wires for osteosynthesis of proximal humeral fractures may cause significant thoracic morbidity, even if various prophylactic measures, including the use of threaded wires, subcutaneous bending, and close radiographic follow-up, are adopted. The use of Kirschner wires should anyway be restricted to carefully selected cases, in order to avoid major complications.- - - - - - - - - - ranking = 1.1806825629662keywords = chest (Clic here for more details about this article) |
7/17. Femoral and tibial fractures in a child with myelomeningocele.Femoral and tibial fractures can occur from accidents, child abuse or pathological causes. It is often very difficult to distinguish the cause among those cases. Radiological diagnosis may be needed for clinicians and medical examiners in order to assist determining the reason of fractures. In this report, we submit a case with femoral and tibial fractures associated with myelomeningocele. This patient was diagnosed as child abuse by clinicians. On review it was decided that her fractures were not because of non-accidental injury. The values of bone mineral density of the upper limb were low and illness caused her fractures.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
8/17. Obstructive sleep apnea uncovered after high spinal anesthesia: a case report.PURPOSE: To illustrate how a patient's previously undiagnosed obstructive sleep apnea was uncovered after administration of a spinal anesthetic with a high sensory blockade, and to discuss possible explanations for this occurrence and anesthetic implications. CLINICAL FEATURES: A 55-yr-old male presented for osteotomy and open reduction and internal fixation of his left femur secondary to malunion from a previous fracture. Past medical history consisted of hypertension, hypercholesterolemia, bipolar disorder, gastroesophageal reflux disease, and cluster headaches. A combined spinal-epidural technique was chosen. Isobaric bupivacaine 0.5% (15 mg), was provided for the spinal anesthetic, along with 1 mg iv midazolam for procedural sedation and 0.5 mg iv droperidol for mild nausea. Throughout the operation, many apneic events were noted, often with respiratory efforts. The patient was easily arousable during each event and would breathe normally until the next episode. vital signs remained stable throughout. Postoperative respirology consultation was requested, and a sleep study revealed severe obstructive sleep apnea. The patient was subsequently started on continuous positive airway pressure with marked improvement in symptoms, including the cluster headaches. CONCLUSION: Recent literature suggests that high spinal blockade can result in altered levels of arousal by producing a de-afferentation of peripheral proprioceptive and sensory stimuli necessary for maintaining an awake state. In patients predisposed to upper airway obstruction, decreasing the level of consciousness can result in airway obstruction as occurs during sleep in these patients. This serves to underline the importance of considering capnography for all cases utilizing a neuraxial anesthetic technique.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
9/17. bone marrow as a means of venous drainage for a microvascular osteocutaneous flap.Intraosseous infusion of fluid had been used in traumatology. Here we describe a clinical situation in which bone marrow is first used for drainage of venous blood in a free osteocutaneous flap. Two factors account for the survival of the large osteocutaneous flap in which venous anastomosis was impossible. (1) In the design of the arterial circuit and the major route of venous drainage, there were two ends of the peroneal artery of the osteocutaneous flap. Both its upper and lower ends were anastomosed to the anterior tibial artery of the recipient site to constitute an uninterrupted arterial circulation. This prevented stagnation of arterial flow and thrombosis of the arterial anastomosis. (2) The major route of venous drainage was through bone marrow. The initial congestion was finally overcome by the development of neovascularization. Bone scan showed good survival of bone with increased uptake of radioactivity. At 3 years follow-up, roentgenogram showed bone union, and the patient had no trouble walking. The continuity of the anterior tibial artery, which had been interrupted by trauma, was restored by this flap.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
10/17. Traumatic hip luxation associated with ipsilateral and contralateral femoral fracture in a child.In children, the association of traumatic luxation of the hip with homo- and heterolateral fracture of the upper extremity of both femurs, is extremely rare. In the case reported here, that association is present. hip luxation can easily pass unrecognized. Orthopedic reduction is always recommended. Regarding the fracture of the upper portion of the femur in children under 10 years, when alignment of the fragments is not well achieved, surgical treatment should be considered. In this case, valgus osteotomy had to be performed in order to correct a post-traumatic coxa vara. After 4 1/2 years of follow up, the only sequel was a 1 cm leg-length discrepancy.- - - - - - - - - - ranking = 2keywords = upper (Clic here for more details about this article) |
