摘 要：
Complications due to vertebroplasty may be divided into two categories whether or not they are related to polymethylmethacrylate (PMMA) cement leakage from the compressed vertebral body. PMMA leakage is a very frequent occurrence in vertebroplasty is also the main source of complications. Neurological complications are due to cement leakage into the spinal canal and less exceptionally into the intervertebral foramen. The transpedicular needle approach reduces the risk of cement leakage into the foramen. Pulmonary embolism of PMMA may occur when there is a failure to recognize venous migration of cement early during the procedure. Cortical destruction, presence of an epidural soft-tissue mass, highly vascularized lesions, and severe vertebral collapse are factors which increase the rate of complications, which is therefore much higher in metastatic than in osteoporotic vertebral collapse. Prevention of PMMA leakage-related complications is a multifactorial issue including procedure preparation, needle approach and placement, and cement application. The technical refinements which may help reduce the risk of PMMA leakage are reviewed in this article. Experimental data have shown that systemic reactions may occur during vertebroplasty in the absence of cement leakage. These reactions may be partly related to vascular embolism of bone marrow fat. Another controversial issue is a possible increase in the risk of vertebral collapse of adjacent vertebrae following vertebroplasty. Prospective randomized studies are needed to resolve this issue.

摘 要：
OBJECTIVE: To determine the demographics, imaging findings, clinical symptoms, and prognosis of primary vertebral Ewing's sarcoma (PVES). DESIGN: A retrospective review of medical records and radiological studies of patients diagnosed with PVES from 1936 through 2001 in our institution and Department of Pathology consultation files was undertaken. Metastatic and soft tissue Ewing's sarcoma cases were excluded. RESULTS: From a total of 1,277 cases of Ewing's sarcoma, 125 (9.8%) had a primary vertebral origin. There were 48 females and 76 males. Patient ages ranged from 4 to 54 (mean 19.3, standard deviation 10.7, median 16) years. Vertebral column distribution was four cervical (3.2%), 13 thoracic (10.5%), 31 lumbar (25%), and 67 sacrum (53.2%). More than one vertebral segment was involved in ten cases (8%). Satisfactory imaging studies were available in 51 patients: 49 radiographs, 27 computerized tomography (CT), and 23 magnetic resonance imaging (MRI) studies. The majority of tumors were lytic (93%). Three cases were mixed lytic and sclerotic (6%) and one sclerotic. In the nonsacral spine, the majority of lesions (12/20) involved the posterior elements with extension into the vertebral body. Five cases were centered in the vertebral body with extension into the posterior elements. Two cases were limited to the posterior elements, and one case solely involved the vertebral body. Ala was the most frequently affected site in the sacrum (18/26). Spinal canal invasion was frequent (91%). Detailed clinical information was available in 53 patients. Duration of symptoms ranged from 1 to 30 (mean 7) months. Local pain was the first symptom and seen in all cases. Neurological deficits were present in 21 (40%) cases. All patients received radiation in various dosages; 70% additionally received chemotherapy. Twenty-five patients had surgery, and two patients received bone marrow transplantation. Forty-five patients had follow-up; the five-year disease-free survival probability is 0.53. Disease-free survival probabilities are 0.60 for sacral tumors and 0.45 for nonsacral tumors. CONCLUSION: PVES is an uncommon tumor, usually seen in the second decade of life (mean age 19.3 years) with a male predilection (62%). An aggressive osteolytic lesion, particularly in the sacrum, should raise suspicion for this tumor in adolescents. Prognosis was similar in sacral and nonsacral tumors.

摘 要：
OBJECTIVE: To try to define an association between clinical history and the finding of isolated teres minor denervation on routine magnetic resonance (MR) examination of the shoulder. DESIGN: A retrospective review of all shoulder MR examinations performed at our institution over a 2-year period ( n=2,563) PATIENTS: All patients and MR examinations demonstrating isolated denervation of the teres minor muscle as determined by review of this subset of patients ( n=61) RESULTS: A 3% incidence of isolated teres minor denervation was found. No patient had a clinical history concerning the classic quadrilateral space syndrome, and no patient had a structural lesion in the quadrilateral space. CONCLUSIONS: Isolated teres minor denervation is not an uncommon finding on routine shoulder MR imaging and may be associated with pathology other than a structural lesion in and about the axillary neurovascular structures, such as rotator cuff injuries and traction injury on the axillary nerve sustained during a glenohumeral joint translational event.

摘 要：
To identify imaging criteria that determine the outcome of core decompression (CD) in femoral-head avascular necrosis (AVN). Radiographs and magnetic resonance imaging (MRI) of 65 hips with early stage AVN treated by core decompression between January 1990 and December 2000 for AVN were reviewed. All hips were categorized into two groups according to the result of CD using total hip arthroplasty (THA) as an end point. Hips that had no THA at follow-up were allocated to group I; those treated with a THA were allocated to group II. CD results were calculated for each group using THA as an end point. The parameters analyzed were the presence or absence of edema associated with the double-line sign on the preoperative MRI, the type of epiphyseal scar (ES) according to Jing, and the type of necrosis according to Mitchell. On follow-up, 45 hips had no THA (group I); 20 patients had a THA (group II). Patients with a radiographic crescent sign and those with edema associated with the double-line sign progressed to THA significantly more frequently. The extent of the necrosis had less discriminatory effect between the two groups. ES and necrotic tissue types had no prognostic value. In regard to the success of CD, it is important to differentiate on MRI between a double line sign plus bone marrow edema and a double-line sign only.

摘 要：
OBJECTIVE: Chordoma is a rare malignant bone tumor that arises from notochord remnants. This is the first trial to investigate the utility of (11)C-methionine (MET) positron emission tomography (PET) in the imaging of chordoma before and after carbon-ion radiotherapy (CIRT). DESIGN AND PATIENTS: Fifteen patients with chordoma were investigated with MET-PET before and after CIRT and the findings analyzed visually and quantitatively. Tumor MET uptake was evaluated by tumor-to-nontumor ratio (T/N ratio). RESULTS: In 12 (80%) patients chordoma was clearly visible in the baseline MET-PET study with a mean T/N ratio of 3.3+/-1.7. The MET uptake decreased significantly to 2.3+/-1.4 after CIRT ( P<0.05). A significant reduction in tumor MET uptake of 24% was observed after CIRT. Fourteen (93%) patients showed no local recurrence after CIRT with a median follow-up time of 20 months. CONCLUSION: This study has demonstrated that MET-PET is feasible for imaging of chordoma. MET-PET could provide important tumor metabolic information for the therapeutic monitoring of chordoma after CIRT.

摘 要：
We describe a recently noted association of congenital (infantile) pseudarthrosis of the lower leg with osteofibrous dysplasia. The patient was a 2-year-old boy who presented with a deformed left ankle joint and three cutaneous cafe-au-lait spots. Radiography demonstrated pseudarthrosis of the left distal fibula and a round lucent lesion adjacent to the proximal part of the pseudarthrosis. Histologically, the surgically removed fibula with pseudarthrosis showed a fibromatosis-like fibrovascular proliferation and nonspecific reparative changes. The focal lucent area demonstrated a fibro-osseous lesion, which was histologically identical to osteofibrous dysplasia. This case provides further evidence that osteofibrous dysplasia may be associated with congenital (infantile) pseudarthrosis of the lower leg.
