Ischemic necrosis of the bones in systemic lupus erythematosus (SLE) usually appears when treatment with corticosteroids is initiated. The most frequent site is the hip, while the knee and shoulder are less frequently involved. A 21-year-old man was admitted because of bilateral shoulder pain 3 years after diagnosis of SLE. The skin, joints, brain, small intestine and kidneys were also involved and corticosteroid therapy was started. 1.5 years before his last admission, severe knee pain developed with limitation of range of movement but without effusion or soft tissue swelling. Bone scan confirmed the diagnosis of aseptic necrosis of the femur and tibia of both knees. He also developed bilateral shoulder pain accompanied by limitation of the range of internal and external rotation. X-ray of the shoulders demonstrated bilateral ischemic necrosis. Since synovitis is relatively rare in SLE treated with corticosteroids, aseptic necrosis of the bone should always be suspected when arthralgia develops in this condition.

Two cases of previously unreported steroid-induced osteonecrosis of the patella were investigated. The first case was a 46-year-old man who had been receiving steroid therapy for three years for treatment of bronchial asthma. The second was a 32-year-old woman who had been receiving steroid therapy for nine years as treatment of systemic lupus erythematosus. Both reported slight knee pain. The roentgenographic findings revealed increased radiodensity with radiolucency of the upper one-half of the patella. A trephine biopsy revealed focal areas of dead trabecular bone.

Magnetic resonance imaging (MRI) was performed on 19 patients with suspected or proven osteonecrosis of the knee. The results were compared to radionuclide and plain radiographic studies when possible. The patients were grouped into one of three categories: patients with disease predisposing them to osteonecrosis (e.g., systemic lupus erythematosus (SLE), steroid use, and renal transplants), older patients without risk factors with acute onset of symptoms,and patients with knee pain months or years following trauma. In six patients with symptoms and predisposing diseases, MRI was abnormal in four cases, all of whom had bilateral abnormalities. In the ten older patients with classical symptoms, MRI was abnormal in seven, and bilateral abnormalities were present in three patients. The three patients with a history of antecedent trauma had normal MRI studies. Two patients with history and scintigraphic evidence of osteonecrosis had negative MRI scans. MRI may be of value in patients with suspected or proven osteonecrosis of the knee by demonstrating bilateral disease in patients with unilateral symptoms, showing the extent of involvement, and establishing the presence or absence of bone marrow changes in patients with positive bone scans and negative plain films.

We surveyed general and family practitioners to evaluate their patterns of referring musculoskeletal disease patients to rheumatologists and orthopedists. Patients who had rheumatoid arthritis, systemic lupus erythematosus, and ankylosing spondylitis were most often referred to rheumatologists, whereas patients with osteoarthritis, persistent low back pain, and post-traumatic knee pain were most often referred to orthopedists. As conditions worsened in severity, referrals were more frequent. Patients with conditions that were difficult to diagnose, such as possible shoulder tendinitis that was unresponsive to initial nonsteroidal therapy, undiagnosed polyarthritis, and intermittent knee swelling with pain, were most often treated without referral and, when referred, were most often sent to orthopedists. Belief in the effectiveness of rheumatologists or orthopedists correlated strongly with reported referral behavior, yet most respondents considered themselves capable of managing the majority of patients with musculoskeletal diseases. Neither practice arrangement, board certification, nor educational background affected referral behavior. However, younger physicians were more likely (P = 0.002) to refer patients to rheumatologists. Multivariate analysis showed that the significant predictors of global referral behavior were belief in the effectiveness of subspecialists and a small number of musculoskeletal problems seen by the generalist. The predictors of referral to rheumatologists were belief in rheumatologist efficacy and young physician age.

Osteonecrosis of the knee should be differentiated into two main categories: (1) primary, spontaneous, or idiopathic osteonecrosis and (2) secondary osteonecrosis (e.g., secondary to factors such as steroid therapy, systemic lupus erythematosus, alcoholism, Caisson decompression sickness, Gaucher's disease, hemoglobinopathies, etc.). Spontaneous or primary osteonecrosis of the knee presents with an acute knee pain in elderly patients. It is three times more common in women than in men. Traumatic and vascular theories have been proposed as a causative factor of osteonecrosis of the knee, but the precise etiology still remains speculative. High index of clinical awareness and a good history and physical examination are essential to make an early, accurate diagnosis. Plain radiographs are often normal during the early course of the disease and, in such instances, radioisotope bone scan and magnetic resonance imaging may be helpful. In the early stage of the disease, nonoperative treatment is indicated and many patients, if diagnosed early, have a benign course with a satisfactory pain relief and a good knee function. In patients with advanced stage of the disease, treatment options include arthroscopic debridement, curettage or drilling of the lesion, bone grafting, high tibial osteotomy, use of osteochondral allograft, and unicompartmental or total knee arthroplasty. The choice of treatment should be based on factors such as age of the patient, severity of symptoms, activity level and functional demands on the knee, site and stage of the lesion, and extent of deformity and secondary osteoarthritis. The clinical features and treatment of steroid-induced osteonecrosis of the knee are briefly discussed. In recent years, "postmeniscectomy" osteonecrosis has been reported, but at present its prevalence and pathophysiology remain unknown. It is possible that this may be a preexisting condition that was not recognized at the time of initial consultation or osteonecrosis may develop after meniscectomy in occasional cases.

Atraumatic secondary osteonecrosis of the patella is a rare entity and has been reported in only several case reports. The purpose of this study was to define the clinical and radiographic characteristics and outcome of this disease. Osteonecrosis of the patella was found in 25 knees in 19 patients. The mean age was 42 years (range, 21-63 years). Eighteen (95%) patients had greater than 2 g of lifetime corticosteroid exposure, and six (32%) patients had systemic lupus erythematosus. Osteonecrosis was found in the superior pole of the patella in all 23 knees (17 patients) that had magnetic resonance imaging. Osteonecrosis was apparent on plain radiographs in five knees (20%) in four patients, and only one knee (4%) in one patient had collapse of the posterior articulating surface of the patella. One (4%) patient presented with anterior knee pain localized to the patella. At a mean followup of 4 years (range, 2-18 years), none of the patients had an intervention that focused on treating the patellar lesion. Patellar osteonecrosis is characterized by patients with coincident lesions of the distal femur and the proximal tibia and lesions localized to the superior pole of the patella. It is a nonprogressive disease that does not warrant surgical exploration.

Associating systemic lupus erythematosus (SLE) with an initial presentation of hemolytic uremic syndrome (HUS) is rare. We report on a 13-year-old boy admitted to our hospital with an initial complaint of bilateral knee pain and multiple petechiae on both lower extremities. Diagnosis of atypical HUS was established according to the clinical triad of HUS without a veriotoxin-producing organism in his stool and the pathological finding compatible to thrombotic microangiopathy. In addition, his symptoms fulfilled the 1982 revised criteria for the classification of SLE. After methylprednisolone and cyclophosphamide pulse therapies, his laboratory findings and general condition improved. No plasmapheresis or any plasma infusion was required.

Musculoskeletal complaints are the most common presenting symptoms in most of the patients with systemic lupus erythematosus (SLE). However, periosteal new bone formation is an extraordinarily rare condition in SLE. We report a case of periosteal reaction in SLE. A 31-year-old woman with SLE presented with both knee pain. Radiographs revealed periosteal reactions in both femur and tibia and around the metaphysis of the right distal tibia. Periosteal reaction can be caused by benign or malignant lesions and infection. We cannot find any other cause of periosteal reaction in our case after thorough evaluations. Periosteal reaction in SLE might be associated with inflammatory vascular changes. This is the first report of periosteal reaction in SLE after the 1990s description and the first report in Korea.

Osteonecrosis of bone is a major cause of morbidity in lupus patients, and is most common in the femoral head. It has been reported in wide range of patients (2-30%). In different studies presence of arthritis, Raynaud phenomenon, vasculitis, pleuritis, antiphospholipid and other factors were associated with this occurrence. Bone infarcts were also associated with these factors. We report a 21-year-old patient who was diagnosed as SLE about 3 years ago. When the patient was stable with hydroxychloroquine and prednisolone referred to rheumatologic clinic for mechanical knee pain, in evaluation she had bone infarct in distal femur. Two months later she came back with bilateral hip pain, and in evaluation she had bilateral osteonecrosis of femoral heads. There are many reports of femoral head osteonecrosis in lupus patients, and also one report of multiple bone infarct and pain in SLE, but we did not find any report of these two phenomena together in a patient whose disease was controlled and she took minimum of steroid and DMARD in the about 2-month follow-up, and this was very interesting for us.

Wilson's disease (WD) is a rare disease, defined as an autosomal recessive disorder characterised by release of free copper and dramatic accumulation of intracellular hepatic copper with subsequent hepatic and central nervous system abnormalities. Mutations of the ATP7B gene are responsible for the metabolic dysfunction. Small open studies have reported spinal radiological abnormalities including scoliosis, diffuse bone demineralisation, osteochondritis and occasionally fracture. Prevalence of osteoporosis in young adult patients is debated, ranging from 10%, with normal mean Z-score values, to 43% in adults. Past history of spinal or peripheral fractures might be present in 50% of patients. Articular disorders include arthralgias of large joints, such as knee pain, rare effusions, early onset of radiological features of osteoarthritis and associated osteochondritis of the knee joint. Radiological chondrocalcinosis, an unusual feature in young adults, has to be confirmed. Few patients may develop drug-induced lupus with arthralgias, positive anti-nuclear and anti-histone antibodies, secondary to D-penicillamine, the major copper chelator used in WD. In this orphan disease, small retrospective studies cannot allow ascertaining definite WD-related articular and bone manifestations. However, such clinical and radiological abnormalities are occasionally the first symptoms leading to diagnosis. Physicians should be aware that unexplained joint pain and effusion, or even radiological features of osteoarthritis, of the large joints in adolescents could suggest WD and lead to copper survey.
