1/10. wood, an organic foreign body of bone. A case report.A case of an organic foreign body consisting of wood in bone is presented along with diagnosis and treatment. The unusual delay in noting the nature and extent of the injury was due to the radiolucence of the object and its lodging within the epiphyseal cartilage.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
2/10. An unusual metallic foreign body in the lateral tibiofemoral compartment.A child presented with pain and swelling of the knee caused by a fall on the snow. Medical imaging showed an unusual metallic foreign body in the lateral tibiofemoral compartment. arthroscopy revealed the nature of the foreign body; a metallic piece of stone had penetrated skin and cartilage and was fastened in the cartilage of the lateral femoral condyle where it caused damage to the cartilage and the anterior horn of the lateral meniscus. A partial meniscectomy was performed.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
3/10. Septic arthritis caused by erysipelothrix rhusiopathiae infection after arthroscopically assisted anterior cruciate ligament reconstruction.A case of septic arthritis caused by erysipelothrix rhusiopathiae, after an arthroscopically assisted anterior cruciate ligament (ACL) substitution in a non-immunosuppressed patient is described. An 18-year-old man underwent an ACL reconstruction with a quadruple hamstring graft. Eight days postoperatively, the patient developed fever, knee pain, and effusion without erythema or suppuration. He was readmitted to the hospital with the diagnosis of septic arthritis. The patient's erythrocyte sedimentation rate, c-reactive protein level, and white blood cell count were high. The joint was aspirated and the fluid was sent for cultures that revealed the presence of E rhusiopathiae. E rhusiopathiae is widespread in nature, it is transmitted by direct cutaneous laceration, and it causes septic arthritis, meningitis, endocarditis, and renal failure in immunosuppressed people with poor prognosis. In our case, the infection was treated with arthroscopic lavage and debridement, retention of the graft and hardware, and intravenous antibiotic administration for 6 weeks, followed by oral administration for 16 weeks.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
4/10. Proximal tibiofibular joint dysfunction and chronic knee and low back pain.This article reports a case of joint dysfunction of the proximal tibiofibular joint that produced knee, thigh and low back pain of 5 yr duration. An injury of a simple nature apparently caused the onset of symptoms. Manipulation of the proximal tibiofibular joint resulted in immediate and dramatic relief of symptoms. This case illustrates how a relatively minor incident can result in longstanding pain and disability. Examination and treatment procedures for the proximal tibiofibular joint dysfunction are described.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
5/10. Isolated anterolateral proximal fibular head dislocation.A 28-year-old woman fell and sustained an isolated anterolateral dislocation of the proximal fibula. This injury generally presents with a characteristic history and associated physical examination and radiographic findings, but the subtle nature of the salient findings contributes to a high degree of misdiagnosis. Emergency physicians should be familiar with this injury because early reduction reduces long-term morbidity.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
6/10. Bone stress injuries causing exercise-induced knee pain.BACKGROUND: No comprehensive studies of bone stress injuries in the knee based on magnetic resonance imaging findings have been published. PURPOSE: Assess the incidence, location, nature, and patterns of bone stress injuries in the knee in military conscripts with exercise-induced knee pain. STUDY DESIGN: Case series; Level of evidence, 4. methods: During a period of 70 months, 1330 patients with exercise-induced knee pain underwent magnetic resonance imaging of the knee. A total of 1577 knees were imaged; the images with bone stress injury findings were retrospectively reevaluated with respect to location and type of injury. The person-based incidence of bone stress injuries in the knee was calculated, based on the number of conscripts within the hospital's catchment area. RESULTS: Of the 1330 patients, 88 (7%) met the inclusion criteria, and 141 bone stress injuries were found in the 110 knees imaged. The incidence of bone stress injuries was 103 per 100 000 person-years. Of the patients, 25% had bilateral bone stress injuries; 28% had 2 solitary bone stress injuries in the same knee simultaneously, all situated in the femoral condyle and tibial plateau. The most common anatomical location for a bone stress injury was the medial tibial plateau (31%), which was also the most typical location for a more advanced injury. After the commencement of military service, a bone stress injury in the medial tibial plateau caused knee pain earlier than did a bone stress injury elsewhere in the knee (P = .014). CONCLUSION: The incidence of bone stress injuries in the knee with exercise-induced knee pain is relatively high in conscripts. Multiple and bilateral injuries can occur. For accurate diagnosis and to ensure appropriate treatment, magnetic resonance imaging is recommended as a routine imaging method when a physical activity can be regularly associated with the onset of symptoms.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
7/10. The use of computerized tomography in the study of the cruciate ligaments of the knee.Computerized tomography was used to investigate the knee joint, without the aid of a contrast medium, in 253 patients referred with a variety of diagnoses. The authors report in particular their experience in the visualization of the cruciate ligaments and assessment of the location, extent and nature of any relative lesions. Computerized tomography proved to be an extremely reliable means of investigating all the capsulo-ligamentous structures, both intra- and extra-articular. The diagnosis was accurate in 94% of cases with disorders of the cruciate ligaments.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
8/10. Wet cement: a poorly recognized cause of full-thickness skin burns.Cement is a rare cause of full-thickness burns. We have examined the aetiology, frequency and severity of these burns, and assessed public awareness of the potential of cement as a caustic agent. Of patients, 95 per cent were unaware of the potential of cement to cause burns, and none had seen precautionary warnings on cement bags or delivery dockets. Factors important in burn production appear to be alkalinity, duration of contact and the abrasive nature of the cement particles. It is concluded that doctors, especially casualty officers, should know of the potential of progressive full-thickness burns from wet cement. General public awareness should be increased. The cement manufacturers were asked to comment on the content of this paper.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
9/10. Supracondylar femur fracture above a mature knee fusion treated with a long locked intramedullary rod.Fracture around a mature knee fusion has been reported in the orthopedic literature, but little has been written regarding treatment options. Closed long anterograde rodding with interlocking screws offers distinct advantages over other methods of reduction and fixation. The closed nature of the procedure avoids excessive soft-tissue stripping. In comparison with a short unlocked rod or plate, the long locked rod imparts more stability and prevents shortening and rotation. We present a case of a supracondylar femur fracture above a mature knee fusion treated in this manner. The literature on this injury is also reviewed.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
10/10. popliteal artery thrombosis associated with trampoline injuries and anterior knee dislocations in children.Recent reports have emphasized the benign nature of trampoline-associated injuries. However, this study describes the limb-threatening problem of popliteal artery thrombosis occurring in association with anterior knee dislocation and trampoline injuries. Three children (ages 11, 13, and 17) were referred to the emergency room within the past 12 months with anterior dislocations of the knee, which occurred while jumping on trampolines. All patients had reduction of their dislocations at outside facilities and were referred within 6 to 12 hours after their injuries, with pulse, motor, and sensory deficits. All patients were taken directly to the operating room, where arteriography confirmed thrombosis of the popliteal artery below the knee. One patient had transection of the artery, whereas two patients had stretch injuries with intimal separation. Each patient required interposition grafting with reversed saphenous vein and underwent concomitant four-compartment fasciotomy. All patients had persistent sensory and motor deficits postoperatively, which were presumed to be a combination of ischemic injury and neuropraxia. All patients have functioning grafts with an average follow-up of 1 year (range, 9-15 months). One patient required a second interposition graft to treat an area of intimal hyperplasia, which developed at the proximal anastomosis, at 6 months postoperatively. Eighty per cent of trampoline injuries are associated with minor injuries with minimal long-term complications. However, dislocations of the knee may be associated with significant arterial injury and amputation rates of up to 30 per cent in many blunt trauma series. Based on our experience, physicians should recognize the possibility of significant arterial injuries occurring in children with anterior knee dislocations while jumping on trampolines.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
