1/133. Three cases of patella fracture in 1,320 anterior cruciate ligament reconstructions with bone-patellar tendon-bone autograft.Between September 1992 and December 1996 we reviewed three transverse displaced fractures of the patella occuring in 1,320 ACL reconstructions using bone-patellar tendon-bone autograft. All the patients suffered local injury to the donor knee between 8 and 12 weeks postoperatively. Immediate rigid fixation using single or double anterior tension band allowed early mobilization and full weight bearing. Between 6 and 9 months after fracture, the screws and the wire were removed and the grafts tested. Results of the pivot shift and Lachman test under anesthesia were negative and arthroscopic visualisation showed the graft to be intact. Postoperative assessment included the Lysholm and Tegner scales, the International Knee documentation Committee Evaluation form (IKDC), KT-1000 arthrometer, and isokinetic dynamometer strength testing. No significant differences in the final outcome were noted between reconstructions complicated by patellar fracture and normal ACL reconstructions.- - - - - - - - - - ranking = 1keywords = fracture (Clic here for more details about this article) |
2/133. Transient peroneal nerve palsies from injuries placed in traction splints.Two patients thought to have distal femur fractures presented to the emergency department (ED) of a level 1 trauma center with traction splints applied to their lower extremities. Both patients had varying degrees of peroneal nerve palsies. Neither patient sustained a fracture, but both had a lateral collateral ligament injury and one an associated anterior cruciate ligament tear. One patient had a sensory and motor block, while the other had loss of sensation on the dorsum of his foot. After removal of the traction splint both regained peroneal nerve function within 6 hours. Although assessment of ligamentous knee injuries are not a priority in the trauma setting, clinicians should be aware of this possible complication in a patient with a lateral soft tissue injury to the knee who is placed in a traction splint that is not indicated for immobilization of this type of injury.- - - - - - - - - - ranking = 0.28571428571429keywords = fracture (Clic here for more details about this article) |
3/133. Distal disinsertion of the patellar ligament combined with avulsion fractures at the medial and lateral margins of the patella. A case report and an experimental study.A 12-year-old boy presented with a proximally retracted patella 5 months after an injury to the left knee. The clinical and radiographic features and the findings at operation led to the conclusion that the original lesion had been a distal disinsertion of the patellar ligament combined with avulsion fractures at the medial and lateral margins of the patella, produced by the medial and lateral longitudinal patellar retinacula. Loading experiments on amputation and cadaver specimens showed that these retinacula, apart from being tendons for the vastus medialis and the vastus lateralis, respectively, constitute a direct fibrous connection of considerable strength between the patella and the tibia and thus are capable of producing avulsion fractures.- - - - - - - - - - ranking = 0.85714285714286keywords = fracture (Clic here for more details about this article) |
4/133. knee dislocation following anterior cruciate ligament disruption without any other ligament tears.We report a rare case of complete knee dislocation following anterior cruciate ligament (ACL) disruption without any other ligament tears. The pathology of the knee joint was torn ACL, intact other ligaments, osteochondral fractures and bone bruise of the lateral femoral condyle, and torn lateral meniscus. In this case, osteochondral fracture resulting from the anteriorly sublaxiation of the tibia following ACL disruption was considered to prevent from spontaneous reduction. This case suggests that anterolateral knee dislocation and spontaneous reduction may occur in ACL injuries.- - - - - - - - - - ranking = 0.28571428571429keywords = fracture (Clic here for more details about this article) |
5/133. Tibial tuberosity avulsion fracture combined with meniscal tear.Avulsion fractures of the tibial tuberosity are uncommon injuries. They usually occur during athletic activities in adolescents. The classification of these injuries has been divided into three types. Only two cases of avulsion fractures of tibial tuberosity have previously been reported with associated damages to menisci. We report a type III fracture of the tibial tuberosity associated with tear of the medial meniscus.- - - - - - - - - - ranking = 1keywords = fracture (Clic here for more details about this article) |
6/133. Clinics in diagnostic imaging (40). iliotibial band syndrome.A 51-year-old male cyclist presented with a mass over the lateral portion of his knee. MR scans showed a cystic collection deep to the iliotibial band (ITB). diagnosis of the ITB syndrome and its differentiation from other cause of painful lateral knee masses, such as meniscal cyst, lateral collateral ligament injury and Segond fracture, are discussed.- - - - - - - - - - ranking = 0.14285714285714keywords = fracture (Clic here for more details about this article) |
7/133. Frozen allogenic spongy bone grafts in filling the defects caused by fractures of proximal tibia.The authors present the way of using the allogenic, frozen, radio-sterilized, spongy bone grafts in operational filling of defects after infra-articular fracture of proximal tibia. Fifteen patients (11 men and 4 women) classified between 30 and 66 years old were evaluated. These patients were operated from 1996 to 1998. The operational treatment with using frozen spongy bone grafts was performed on patients with comminuted split fracture of lateral condyle and depression of tibial plateau. In each case after elevating depressed fragment of tibial plateau bone grafts and screws were used to create a stable joint surface. In the same time other injured structures of the joint (ligaments, meniscus) were being reconstructed. To evaluate the stage of grafts incorporation, radiological examinations were made in; 4 weeks, 8 weeks, 6 months, 1 year from the date of the operation. We observed the process of calcification and forming trabeculac in bone grafts. The mechanical abilities of the reconstructed joint were evaluated according to the IKDS and Lysholm score. In all cases the spongy bone grafts in the joint were reconstructed and rebuild successfully. Thirteen patients had good and very good results in further clinical examinations. We claim that frozen, allogenic grafts of the spongy bone are very useful in filing detects of that bone caused by complicated injuries. This method of treatment with its good results is recommended.- - - - - - - - - - ranking = 0.85714285714286keywords = fracture (Clic here for more details about this article) |
8/133. 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 = 0.71428571428571keywords = fracture (Clic here for more details about this article) |
9/133. Nonunion of a Hoffa fracture in a child.The authors report a case of a Hoffa fracture of the lateral femoral condyle that subsequently went on to nonunion in an eight-year-old child. The child presented with symptoms of knee pain and snapping five years after a motor vehicle accident. The nonunion fragment involved most of the lateral femoral condylar articular surface but spared the physis. After treatment by open reduction and limited internal fixation, the nonunion has healed, and the child has virtually full range of motion of the knee and no evidence of growth disturbance.- - - - - - - - - - ranking = 0.71428571428571keywords = fracture (Clic here for more details about this article) |
10/133. A case of intra-articular fracture of the knee joint with three layers within lipohemarthrosis by ultrasonography and computed tomography.We report a case of intra-articular fracture of the knee joint showing three layers within lipohemarthrosis. Sagittal ultrasonography showed three layers (double fluid-fluid level): a superior hyperechoic layer of fat, an intermediate anechoic layer of serum, and an inferior hypoechoic layer of red blood cells. Horizontal computed tomography imaging demonstrated the same three layers. This is the first case of lipohemarthrosis in which three layers of joint effusion were confirmed by both ultrasonography and computed tomography.- - - - - - - - - - ranking = 0.71428571428571keywords = fracture (Clic here for more details about this article) |
