摘 要：
Posterior shoulder instability refers to the symptoms and signs resulting from excessive posterior translation of the humerus. Magnetic resonance (MR) imaging is the radiological modality of choice in the diagnostic assessment of posterior instability. Computed tomography (CT) is useful in the evaluation of osseous abnormalities associated with posterior instability. A detailed description of the posterior osseous and labroligamentous abnormalities has evolved recently, and many variant lesions of the posteroinferior labrum and/or capsular structures have been described. As the recommended surgical management of lesions associated with posterior instability is a lesion-specific approach, awareness of the specific lesions that have been described in association with posterior instability helps in pre-surgical planning. The purpose of this article is to review the classification of, and injury mechanisms leading to, posterior shoulder instability and to describe imaging findings associated with posterior instability, with emphasis on MR imaging.

摘 要：
OBJECTIVE: The objective was to evaluate the piriformis muscles and their relationship to the sacral nerve roots on T1-weighted MRI in patients with no history or clinical suspicion of piriformis syndrome. PATIENTS AND METHODS: Axial oblique and sagittal T1-weighted images of the sacrum were obtained in 100 sequential patients (200 pairs of sacral roots) undergoing routine MRI examinations. The relationship of the sacral nerve roots to the piriformis muscles and piriformis muscle size were evaluated, as were clinical symptoms via a questionnaire. RESULTS: The S1 nerve roots were located above the piriformis muscle in 99.5% of cases (n=199). The S2 nerve roots were located above the piriformis muscle in 25% of cases (n=50), and traversed the muscle in 75% (n=150). The S3 nerve roots were located above the piriformis muscle in 0.5% of cases (n=1), below the muscle in 2.5% (n=5), and traversed the muscle in 97% (n=194). The S4 nerve roots were located below the muscle in 95% (n=190). The piriformis muscles ranged in size from 0.8-3.2 cm, with an average size of 1.9 cm. Nineteen percent of patients had greater than 3 mm of asymmetry in the size of the piriformis muscle, with a maximum asymmetry of 8 mm noted. CONCLUSION: The S1 nerve roots course above the piriformis muscle in more than 99% of patients. The S2 roots traverse the piriformis muscle in 75% of patients. The S3 nerve roots traverse the piriformis muscle in 97% of patients. Piriformis muscle size asymmetry is common, with muscle asymmetry of up to 8 mm identified.

摘 要：
INTRODUCTION: Resurfacing metal-on-metal hip arthroplasty is increasing in popularity, especially in younger patients. To date, studies indicate that the procedure is associated with a good outcome in the medium-term. Formation of a peri-articuar mass is a rarely reported complication. In this study we analyse the imaging findings in patients with resurfacing implants presenting to our institution with peri-articular masses identified on cross sectional imaging. MATERIALS AND METHODS: All patients with documented peri-articular masses following resurfacing arthroplasty were included. The available imaging related to the masses was reviewed and the findings documented along with the patient's demographics. RESULTS: There were 10 patients (13 joints). All patients were female. Patients presented with periprosthetic anterior or posterolateral solid and cystic masses. The anterior masses involved psoas muscle and were predominately solid. The posterolateral masses were predominately cystic. In the three cases with bilateral arthroplasties, masses were detected in both hips. Histology in six cases showed features compatible with a type IV hypersensitivity reaction. CONCLUSIONS: The preponderance of females, the bilateral nature of the masses and the histological features suggest that peri-articular masses following resurfacing arthroplasty is due to the metal hypersensitivity.

摘 要：
OBJECTIVE: The objective was to evaluate bone mineral density (BMD) changes around the proximal femur after implantation of two different anatomical stems. MATERIALS AND METHODS: Thirty-six patients (19 women and 17 men) who underwent total hip replacement were recruited. A Bihapro stem was implanted in 23 patients (with a mean age of 60.9 years) and a Citation stem in 13 patients (with a mean age of 59.7 years). All patients underwent serial radiography of the affected hip (follow-up time: 12 months). Baseline periprosthetic and overall BMD were measured with dual-energy X-ray absorptiometry (DEXA) 1 week and 12 months after hip replacement. Regions of interest (ROIs) were defined according to Gruen's system (ROIs 1-7). RESULTS: All stems were classified as radiographically stable. Bone ongrowth (spot welds) was present in zones 1 and 2 in all patients with the Bihapro stem. The distribution of baseline densities was very similar in the two groups of patients. In Bihapro implants a significant increment of mineralisation was present in ROI 1 after 1 year; ROIs 2 to 7 showed no density variation. The following observations were made regarding the Citation implants: no increment in density was shown in ROI 1; the differences in densities among the ROIs were significant after 1 year in the global evaluation (p = 0.004); the comparison between the single ROIs showed decalcification in ROIs 2 and 7 and a density increment in ROI 5. CONCLUSIONS: Bihapro stems appear to achieve adequate proximal fixation, avoiding the "stress shielding" phenomenon.

摘 要：
OBJECTIVE: The objective of this study was to describe and validate a simple method to quantitatively calculate the missing area of the anterior part of the glenoid in anterior glenohumeral instability. MATERIALS AND METHODS: The calculations were developed from three-dimensional (3D)-reconstructed computerized tomography en face images of the glenoid with "subtraction" of the humeral head in 13 consecutive cases with known anterior glenohumeral joint instability diagnosed by history and clinical examination. The inferior portion of the glenoid was approximated to a true circle whose center was determined by means of a femoral head gauge. The eroded anterior area was calculated as the ratio between the depth (a perpendicular line from the center of the circle to the eroded edge of the anterior glenoid) and the radius of the inferior glenoid circle. This data was then compared to the results obtained by two additional different methods: direct computerized measurements of the missing area and direct computerized measurement of the ratio between the radius and depth, on two dimensional computed tomography (CT) en face view reconstructions of the glenoid. RESULTS: We provide a function that correlates the ratio between depth and radius of the inferior glenoid circle and the area of the missing anterior glenoid. The results obtained by three different methods were comparable. Simple trigonometric calculations showed that a 5% area defect corresponds to 0.8 (12.5%) of the radius of the inferior glenoid, while a 20% area defect corresponds to 0.5 (50%) of the same radius (Table 1).

摘 要：
OBJECTIVE: The objective of this paper was to demonstrate the prevalence of shoulder magnetic resonance imaging (MRI) abnormalities, including abnormal bone marrow signal at the acromioclavicular (AC) joint in symptomatic and asymptomatic Ironman Triathletes. MATERIALS AND METHODS: The shoulders of 23 Ironman Triathletes, seven asymptomatic (group I) and 16 symptomatic (group II), were studied by MRI. A separate, non-triathlete group was evaluated specifically for AC joint marrow signal abnormalities to compare with the Ironman Triathletes. RESULTS: Partial thickness tears of the rotator cuff, rotator cuff tendinopathy, and AC joint arthrosis were common findings in both groups of triathletes. Tendinopathy was the only finding that was more prevalent in the symptomatic group, but this was not a statistically significant difference (p = 0.35). There were no tears of the glenoid labrum seen in group I or II subjects. Of note is that 71% (5/7) of group I subjects and 62% (10/16) of group II subjects had increased signal changes in the marrow of the AC joint (p = 0.68). The comparison group showed a lower prevalence (35%, p = 0.06) of this finding. CONCLUSIONS: No statistically significant difference was found among the findings for group 1, group 2, or the comparison group, although the difference between the comparison group and Ironman Triathletes approached statistical significance when evaluating for AC joint abnormal signal. Shoulder MRI of Ironman Triathletes should be interpreted with an appreciation of the commonly seen findings in asymptomatic subjects.

摘 要：
OBJECTIVE: The aim of this study was to differentiate septic from non-septic arthritis by measuring lactate concentration with (1)H magnetic resonance spectroscopy (HMRS) and by estimating total protein content with the assessment of T (2) values. MATERIALS AND METHODS: In 30 patients with acute arthritis, synovial fluid was aspirated. Lactate concentrations were analyzed with single voxel HMRS at 1.5 T. T (2) relaxation times were mapped with a multi-spin echo sequence. All samples underwent microbiological testing and routine laboratory analysis to quantify lactate concentration and total protein content. Values obtained in septic and non-septic arthritis were compared with a Mann-Whitney U test. RESULTS: Synovial fluid from patients with septic arthritis (n = 10) had higher concentrations of lactate (11.4 +/- 4.0 mmol/L) and higher total protein content (51.8 +/- 10.7 g/L) than fluid obtained in non-septic arthritis (n = 20; 5.2 +/- 1.1 mmol/L and 40.4 +/- 6.9 g/L, respectively, p < 0.001 and <0.01, respectively). Measured lactate concentrations and T (2) relaxation times (as an indicator of total protein content) were moderately correlated to laboratory-confirmed lactate concentration (r (2) = 0.71) and total protein content (r (2) = 0.73). Markedly increased lactate concentrations (>6 mmol/L) in combination with low T (2) values (<550 ms) identify septic arthritis with a sensitivity of 70% and a specificity of 89%. CONCLUSION: Spectroscopic measurements of lactate concentration in combination with the estimation of protein content using T (2) may be of value in the differentiation of septic from non-septic arthritis.

摘 要：
AIM: Clavicle is a unique bone for many reasons. There is no study discussing the differential diagnosis of clavicular lesions based on the site of occurrence or age at presentation. This study aims to determine whether the distribution of lesions affecting the clavicle and age at presentation aid in the differential diagnosis of focal clavicular lesions. MATERIALS AND METHODS: Clinical notes, imaging and histopathological reports of the clavicular lesions between Jan 1999 and Jan 2006 were reviewed. Virtually, all patients had been referred as suspected neoplasm. RESULTS: Fifty-nine patients were identified. Patients <20 years (n = 27) had non-neoplastic or benign lesions. Patients between 20-50 years (n = 14) had predominantly non-neoplastic lesions. Patients >50 years (n = 18) had predominantly malignant lesions. The lesions most commonly affected the medial third (n = 35) and were predominantly non-neoplastic or benign. The middle third was affected in 15 patients and showed both benign and malignant lesions. The lateral third was least affected with predominance of malignant lesions. CONCLUSIONS: The clavicle is not a primary common site for any particular tumour; hence, diagnosis of the lesions can be challenging. Our study has suggested that few factors like age and site of the lesions may be helpful in diagnosis.

摘 要：
Sarcoidosis is a systemic disease that histologically typically shows non-caseating granulomas. The most common radiologic finding is hilar and mediastinal adenopathy. Patients with widely disseminated disease may show involvement of the peripheral appendicular skeleton in 1-13% of such cases. A primary skeletal presentation without other manifestations typical of the disease is rare. We present a case of sarcoidosis in a middle-aged Caucasian man in whom the disease presented with widespread lytic lesions in the axial skeleton and long bones, mimicking metastatic disease. There was no involvement of the peripheral skeleton, skin or lungs.

摘 要：
We present the case of a 41-year-old man with known large cell lung cancer who had undergone left pneumonectomy 7 months prior and who presented with a large intramuscular mass involving the posterior left thigh and upper calf. This thigh mass was ultimately surgically explored, and specimens yielded both Escherichia coli organisms and cells reflecting a skeletal muscle metastasis from the patient's known lung cancer. The patient was also found to have a rectal metastasis from his lung cancer. Intramuscular abscesses produced by gastrointestinal tract flora are a well-known presentation of colon cancer. To our knowledge, this is the first case report of the simultaneous occurrence of a skeletal muscle metastasis and an E. coli abscess in the same anatomic location. We believe the patient's rectal metastasis may have been the intermediate step in this process.

摘 要：
Pseudomeningocele is an uncommon but well-known complication of lumbar spine operations. Although it is mostly asymptomatic and managed conservatively in most cases, it is claimed as a causative factor of failed back surgery syndrome and requires surgery in some cases. Usually, its diagnosis is confidently done with imaging modalities such as magnetic resonance imaging, computed tomography and myelography. In this report, we describe a case of pseudomeningocele that communicated with a facet joint. The diagnostic approach for this unusual lesion and its probable causes are discussed.

摘 要：
We report on the case of a 70-year-old woman presenting with right hip pain. Radiographs of the right hip demonstrated a well-defined large lytic lesion in the proximal right femur, with prominent trabeculae situated peripherally and extending into the lesion in a "spoke-wheel" pattern. Magnetic resonance imaging (MRI) demonstrated solid enhancing marrow-replacing lesion, with intervening linear nonenhancing areas of low T2 signal intensity. The MRI appearance resembled that of a small brain or "mini brain". Biopsy specimen demonstrated predominantly mature plasma cells, with occasional admixed immature forms. A diagnosis of plasmacytosis, consistent with myeloma, was made. This case illustrates a rare but seemingly characteristic "mini brain" appearance of plasmacytoma, which, to date, has only been reported in the spine and has not been observed in other bony lesions.
